For example, the coupling member 1220 may include a latch part, and the cooling tip 2000 may be mounted to the cooling device 1000 by hooking the latch part to a groove included in the cooling tip 2000 . In addition, when the latch portion of the coupling member 1220 is separated from the groove of the cooling tip 2000 in a state where the cooling tip 2000 is mounted on the cooling device 1000 , the cooling tip 2000 is separated from the cooling device 1000 . can be Here, for the operation of the coupling member 1220, the coupling module 1200 may further include an elastic body. For another example, the coupling member 1220 is fixed to the base 1210 together with the elastic body, and one end of the coupling member 1220 is applied with an external force due to a user input, etc. in a state in which the coupling member 1220 rotates in one direction. When the external force is removed, the coupling member 1220 may rotate to its original state by the elastic body. The operation of the coupling member 1220 will be described in detail later.

A plurality of coupling members 1220 may be implemented. For example, referring back to FIG. 5 , the base 1210 includes a first coupling member 1221 and a second coupling member 1222 , and includes the first coupling member 1221 and the second coupling member 1222 . The cooling tip 2000 may be mounted on or separated from the coupling module 1200 through the coupling module 1200 .

The coupling member 1220 may be fixed to the base 1210 through a coupling member fixing pin LP. For example, in a state in which the coupling member 1220 is disposed on the outer surface of the base 1210 , the coupling member fixing pin LP passes through the coupling member 1220 and is inserted into the base 1210 so that the coupling member 1220 is the base. 1210 may be fixed.

One end of the elastic member 1300 may be fixed to the base 1210 through the elastic member fixing pin SP. For example, in a state in which one end of the elastic member 1300 is disposed inside the base 1210, the elastic member fixing pin SP passes through one end of the elastic member 1300 and is inserted into the base 1210, whereby the elastic member ( One end of the 1300 may be fixed to the base 1210 .

On the other hand, it has been described that the coupling member 1220 and the elastic member 1300 are fixed to the base 1210 using the coupling member fixing pin LP and the elastic member fixing pin SP, respectively, but the technical idea of the present specification is not The present invention is not limited thereto, and the coupling member 1220 and the elastic member 1300 may be fixed or coupled to the base 1210 using a force fit, screw coupling, latch coupling, or magnetic coupling.

The mounting confirmation member (CCM) may detect whether the cooling tip 2000 is mounted on the coupling module 1200 . For example, as shown in FIG. 5, the mounting confirmation member (CCM) is disposed inside the coupling module 1200 to detect that the cooling tip 2000 is mounted to the coupling module 1200 and to the control module 1800. Information regarding the mounting of the cooling tip 2000 may be provided. The mounting confirmation member (CCM) may be composed of a switch, a pressure sensor, a touch sensor, or a combination thereof operated by an external force to detect whether the cooling tip 2000 is mounted. Meanwhile, the mounting confirmation member CCM may be attached to the cooling medium accommodating member 1120 .

As described above, the coupling module 1200 includes the coupling member 1220 so that the cooling tip 2000 can be detached and at the same time the cooling module 1100 is disposed in the cooling device 1000 to move the cooling module ( 1100) can be connected. As such, the coupling module 1200 performs various roles, thereby optimizing the arrangement of components in the cooling device 1000 , and furthermore, the assembling of the cooling device 1000 may be improved. In addition, such a coupling module 1200 allows a user to quickly and easily separate the cooling tip 2000 from the cooling device 1000, so that cooling of the target can be stopped immediately in an emergency.

6 is a view showing a cooling module 1100 according to an embodiment of the present specification.

Referring to FIG. 6 , the cooling module 1100 may include a cooling medium 1110 , a cooling medium accommodating member 1120 , a temperature control member 1130 , a heat dissipation member 1140 , and a tube.

The cooling medium 1110 may be thermally coupled to the temperature control member 1130 . For example, referring back to FIG. 6 , the cooling medium 1110 is a first surface S1 in contact with one surface of the first temperature control member 1131 and one surface of the second temperature control member 1132 in contact with A second surface S2 may be included. The cooling medium 1110 may receive cooling energy from the first and second temperature control members 1131 and 1132 through the first surface S1 and the second surface S2 .

Here, the cooling medium 1110 and the temperature control member 1130 may be implemented in a shape for efficiently exchanging cooling energy or thermal energy. For example, at least a portion of the cooling medium 1110 and the temperature control member 1130 may be implemented in a rectangular parallelepiped shape in order to be in surface contact. Meanwhile, the shapes of the cooling medium 1110 and the temperature control member 1130 are not limited to the above-described rectangular parallelepiped, and of course, may be implemented in various shapes for making surface contact.

The cooling medium accommodating member 1120 may accommodate the cooling medium 1110 . For example, at least a portion of the cooling medium 1110 may be inserted into the cooling medium accommodating member 1120 to pass through the cooling medium accommodating member 1120 . At this time, in order to minimize the moisture that forms when the cooling medium 1110 is cooled below the dew point, the cooling medium 1110 penetrates in close contact with the cooling medium accommodating member 1120 or the cooling medium 1110. A sealing member may be used in passing through the cooling medium accommodating member 1120 . In addition, a hydrophobic coating may be applied to the surface of the cooling medium 1110 to minimize moisture formation.

The cooling medium accommodating member 1120 may include a coupling hole for coupling with the heat dissipating member 1140 . For example, the cooling medium accommodating member 1120 may include at least one coupling hole corresponding to at least one screw hole formed in the heat dissipating member 1140 to be mechanically coupled to the heat dissipating member 1140 . have.

The temperature control member 1130 may be fixed in a state in which it is thermally coupled to the cooling medium 1110 and the heat dissipation member 1140 . For example, referring back to FIG. 6 , the first temperature control member 1131 is disposed between the cooling medium 1110 and the first heat dissipation member 1141 , and the second temperature control member 1132 is disposed between the cooling medium 1110 . ) and the second heat dissipation member 1142 in the state disposed between the first heat dissipation member 1141 and the second heat dissipation member 1142 are coupled to press the first and second temperature control members 1131 and 1132, The first temperature control member 1131 and the second temperature control member 1132 may be fixed in surface contact with the cooling medium 1110 .

Here, when the temperature control member 1130 includes one surface and the other surface that absorb or generate heat according to the direction of the applied current, one surface of the temperature control member 1130 is in contact with the cooling medium 1110 and the temperature control member 1130 The other surface of the may be in contact with the heat dissipation member 1140 . At this time, the temperature control member 1130 may transmit cooling energy to the cooling medium 1110 through one surface, and thermal energy generated as a supply opposite to the generation of cooling energy is transmitted to the heat dissipation member ( 1140).

As described above, according to the operation of the temperature control member 1130 , the cooling medium 1110 receives cooling energy, and the heat dissipation member 1140 receives the thermal energy corresponding to the cooling energy and discharges it to the outside of the cooling device 1000 . By doing so, the cooling efficiency of the cooling device 1000 may be increased and durability of the cooling device 1000 may be improved.

Meanwhile, when the temperature control member 1130 stops or stops the operation, the heat dissipation member 1140 may have different physical properties from the cooling medium 1110 in order to increase the lowered temperature of the cooling medium 1110 . For example, the heat dissipation member 1140 may have a heat capacity greater than that of the cooling medium 1110 (preferably, a heat capacity of at least twice the heat capacity of the cooling medium 1110 ). Specifically, the heat dissipation member 1140 may be made of the same material as the cooling medium 1110 but have a large mass. Alternatively, the heat dissipation member 1140 may be made of a material having a higher specific heat than the cooling medium 1110 . Accordingly, as will be described later, when the operation of the cooling device 1000 is stopped, heat transfer from the cooling medium 1110 to the heat dissipation member 1140 is accelerated to thermally couple the cooling medium 1110 and the cooling tip 2000 through the target. The surface temperature can rise quickly and safely.

The heat dissipation member 1140 may be connected to the cooling medium accommodating member 1120 . For example, referring back to FIG. 6 , the cooling medium accommodating member 1120 is disposed between the first heat dissipation member 1141 and the second heat dissipation member 1142 , and the first and second heat dissipation members 1141 and 1142 . ) and a coupling means such as a fixing pin or a screw is inserted into the coupling hole of the cooling medium accommodating member 1120 and the heat dissipating member 1140 and the cooling medium accommodating member 1120 may be coupled to each other.

The heat dissipation member 1140 may include a heat pipe and a plurality of heat dissipation fins to radiate the thermal energy provided from the temperature control member 1130 at a location spaced apart from the cooling medium 1110 by a predetermined distance.

As described above, the heat dissipation member 1140 may be divided into a coupling portion coupled to the cooling medium accommodating member 1120 , a heat pipe transferring the received thermal energy, and a heat dissipation portion including a plurality of heat dissipation fins. The heat dissipation member 1140 receives thermal energy from the coupling portion, moves the received thermal energy through the heat pipe, and radiates heat to the outside through the heat dissipation portion. Here, the coupling part, the heat pipe, and the heat dissipation part may be integrally formed that are not physically separated, or may be physically separated from each other to constitute the heat dissipation member 1140 by assembly.

The heat dissipation member 1140 may accommodate a tube to be described later. For example, when the first and second heat dissipation members 1141 and 1142 are coupled, the first heat dissipation member 1141 and the second heat dissipation member 1142 correspond to the inner tube, respectively, so that a hollow into which the tube is inserted is formed. It may include a groove to

The other end of the elastic member 1300 may be fixed to the heat dissipation member 1140 . For example, referring back to FIG. 6 , the first heat dissipation member 1141 and the second heat dissipation member 1142 may be coupled through a plurality of coupling pins or coupling screws, and a first elastic member may be attached to each coupling pin or coupling screw. The other end of the member 1310 and the other end of the second elastic member 1320 may be fixed. As a result, one end of the elastic member 1300 is connected to the main body and the other end of the elastic member 1300 is connected to the cooling module 1100. This position can be moved.

Meanwhile, the other end of the elastic member 1300 may be fixed to other components of the cooling module 1100 in addition to the heat dissipation member 1140 . However, when the other end of the elastic member 1300 is fixed to the cooling medium 1110 , cooling energy loss of the cooling medium 1110 may occur, and the other end of the elastic member 1300 is connected to the heat dissipation member 1140 to dissipate heat. It may be preferable to be connected to the heat dissipation member 1140 because it can assist.

The sensor module 1400 may be inserted into the cooling medium 1110 . For example, the sensor module 1400 may be inserted into the cooling medium 1110 along the central axis CA to acquire temperature information of the cooling medium 1110 in real time. Meanwhile, the sensor module 1400 may measure the temperature of the cooling medium 1110 by contacting or not in contact with the cooling medium 1110 without being inserted into the cooling medium 1110 .

The cooling module 1100 may include a tube. The tube may pass a power supply line or a sensor module 1400 necessary for generating cooling energy. For example, a wire for supplying power to the temperature control member 1130 or a temperature sensor for measuring the temperature of the cooling medium 1110 may be disposed to pass through the tube. Here, the tube may be made of a material having low thermal conductivity, such as plastic, for effective thermal insulation of the cooling medium 1110 .

On the other hand, in the above, the cooling module 1100 is implemented by being symmetrically coupled to the cooling medium 1110 with the plurality of temperature control members 1130 and the plurality of heat dissipation members 1140 based on the central axis CA. Although mainly described, the technical spirit of the present specification is not limited thereto. For example, the temperature control member 1130 and the heat dissipation member 1140 are sequentially disposed on one surface of the cooling medium 1110, and the above-described cooling medium 1110 is inserted into the cooling medium accommodating member 1120. The cooling module ( 1100 may be implemented in various structures that provide cooling energy to the cooling medium 1110 and discharge heat generated accordingly.

Also, in the cooling tip 2000 , the contact member 2100 may be mounted on the tip body 2200 or separated from the tip body 2200 . For example, the cooling tip 2000 may be mounted on the cooling device 1000 along the central axis CA. At this time, the cooling tip 2000 is mounted on the cooling device 1000 or separated from the cooling device 1000 in a state in which the contact member 2100 is fixed to the tip body 2200 by an intermediate fit or an interference fit. can

The cooling tip 2000 may be mounted on the cooling device 1000 to improve cooling energy transfer efficiency. For example, when the cooling tip 2000 is mounted on the cooling device 1000 , the cooling medium 1110 is in physical contact with the contact member 2100 , and the cooling medium receiving member 1120 is in contact with the tip body 2200 . can be connected through In other words, the cooling medium 1110 may provide cooling energy intensively to the contact member 2100 of the cooling tip 2000 .

8 is a view illustrating an aspect in which the cooling tip 2000 according to an embodiment of the present specification is mounted on the cooling module 1100 .

Referring to FIG. 8 , the tip body 2200 and the contact member 2100 may be detachably attached to the cooling medium accommodating member 1120 and the cooling medium 1110 along the central axis CA. As described above, in order to improve the cooling efficiency and durability of the cooling device 1000 , the cooling medium 1110 , the cooling medium receiving member 1120 , the contact member 2100 , and the tip body 2200 may have a shape corresponding to each other. can

The cooling medium 1110 may include an insertion part inserted into the cooling medium accommodating member 1120 and a protruding part protruding from the cooling medium accommodating member 1120 . Referring back to FIG. 9 , the cooling medium 1110 may include an insertion portion having a first length L1 and a protruding portion having a second length L2 and a first width W1 . Here, the insertion part may be implemented in a tapered shape in which a cross section of one end is a rectangle, a cross section of the other end is a circle, and the width is narrowed from one end to the other end. Here, the protruding portion may be implemented in a cylindrical shape.

The cooling medium accommodating member 1120 may include a receiving portion through which the insertion portion of the cooling medium 1110 passes. For example, the cooling medium accommodating member 1120 may include a accommodating portion having a third length L3 and a third width W3 and having a hollow therein. Here, the third length L3 corresponds to the first length L1 of the insertion portion of the cooling medium 1110 so that the protruding portion of the cooling medium 1110 may protrude from the cooling medium accommodating member 1120 by a predetermined length, and The hollow may have a shape corresponding to the shape of the insertion portion of the cooling medium 1110 .

The contact member 2100 may have a shape corresponding to the protruding portion of the cooling medium 1110 .

It may include an internal space of the shape. Here, as the second length L2 of the protruding portion of the cooling medium 1110 is greater than or equal to the fourth length L4 of the inner space of the contact member 2100 , as will be described later, the cooling medium 1110 is the contact member By pressing (2100) can be more firmly fixed to the tip body (2200). Also, here, the first width W1 of the protruding portion of the cooling medium 1110 is smaller than or equal to the second width W2 of the inner space of the contact member 2100, so that the cooling tip 2000 from the cooling device 1000 is It can be mounted and detached more easily, and damage to the cooling medium 1110 can be prevented during mounting and detachment. When the first width W1 of the protruding portion of the cooling medium 1110 is less than or equal to the second width W2 of the inner space of the contact member 2100, one surface of the contact member 2100 in contact with the target surface is in contact It may have a larger area than one surface of the protruding portion of the cooling medium 1110 in contact with the member 2100 .

The tip body 2200 may have a shape corresponding to the cooling medium accommodating member 1120 . For example, when the cooling medium accommodating member 1120 has a cylindrical shape having a third length L3 and a third width W3, the tip body 2200 has a fourth width equal to or greater than the third width W3. It may include an internal space having a fifth length L5 having a length W4 and shorter than the third length L3. Here, the third width W3 corresponds to the fourth width W4 , or the inner diameter of the opening of the tip body 2200 corresponds to the outer diameter of the cooling medium receiving member 1120 , so that the center of the cooling medium 1110 . In a state in which the shaft and the central axis of the contact member 2100 correspond, the cooling tip 2000 is mounted and separated in the cooling device 1000. As a result, the cooling medium 1110 can be prevented from being worn or damaged. In addition, the fifth length L5 may be configured such that the coupling force applied by the elastic member 1300 can be concentrated between the cooling medium 1110 and the contact member 2100 of the cooling tip 2000, and thus the cooling medium The efficiency of heat transfer between the contact member 2100 of the 1110 and the cooling tip 2000 may be increased.

On the other hand, in order to prevent damage to the cooling medium 1110 according to the mounting of the cooling tip 2000, the protruding part in contact with the contact member 2100 of the cooling tip 2000 of the cooling medium 1110 is coated with a wear-resistant material. can For example, it may be coated with a metal such as nickel or chromium. Alternatively, a coating member may be included between the cooling tip 2000 and the cooling medium 1110 . At this time, the coating member may be made of a material softer than the contact member 2100 of the cooling tip 2000 . Specifically, the coating member may have a hardness of 2.5 or less Mohs Hardness, and preferably may have a hardness of 2 or less Mohs Hardness.

In addition, the cooling medium 1110, the cooling medium receiving member 1120, the contact member 2100, and the tip body 2200 described above are not limited to the above-described shape or size, for example, the cooling medium 1110 Of course, the cross-section of the protruding part of ) and the cross-section of the contact member 2100 of the cooling tip 2000 may be implemented in various shapes, such as polygons.

9 is a view illustrating that the cooling tip 2000 according to an embodiment of the present specification is separated from the cooling device 1000 .

Referring to FIG. 9 , the cooling tip 2000 may be separated from the cooling device 1000 according to the operation of the coupling member 1220 while the cooling tip 2000 is mounted on the cooling device 1000 .

Hereinafter, for convenience of description, a case in which the coupling member 1220 includes a clasp portion and the cooling tip 2000 includes a groove corresponding to the clasp portion will be described, but the technical spirit of the present specification is not limited thereto.

Referring back to FIG. 9 , the cooling tip 2000 may be mounted to the cooling device 1000 by the coupling member 1220 . Specifically, the cooling tip 2000 by engaging the latch portion of the first coupling member 1221 and the second coupling member 1222 symmetrically arranged with respect to the central axis CA in the groove of the cooling tip 2000. It may be mounted on the cooling device 1000 .

When pressure is applied to one end of the coupling member 1220 , the cooling tip 2000 may be separated from the cooling device 1000 . For example, referring back to FIG. 9 , when one end of the first coupling member 1221 and the second coupling member 1222 is pressed by the user, respectively, the first coupling member 1221 and the second coupling member 1222 By rotating about the coupling member fixing pin (LP) as an axis, each latch portion is separated from the groove of the cooling tip 2000, the cooling tip 2000 can be separated from the cooling device (1000). Here, in order to separate the cooling tip 2000 from the cooling device 1000 , an elastic force by the elastic member 1300 may act in the direction of the central axis CA, as will be described later.

As such, since the cooling tip 2000 is easily separated from the cooling device 1000 by a simple operation, the user can immediately stop cooling in an emergency. At this time, so that the cooling tip remains attached to the target by ice adhesion and does not apply excessive force to the target due to gravity, the cooling tip 2000 may be configured lightly, and specifically may be configured to be 2 g or less. And, more specifically, it may be composed of 1 g or less.

10 is a view illustrating the operation of the elastic member 1300 as the cooling tip 2000 is mounted/detached to the cooling device 1000 according to an embodiment of the present specification. The cooling tip 2000 deforms the elastic member 1300 while being mounted on the cooling device 1000 , and the cooling tip 2000 is separated from the cooling device 1000 by the restoring force or elastic force of the deformed elastic member 1300 . can

Hereinafter, a case in which the elastic member 1300 is composed of a tension spring and is mounted symmetrically with respect to the central axis CA is mainly described, but the technical spirit of the present specification is not limited thereto, and a compression spring, torsion Of course, similarly applicable to a case in which at least one object capable of using a restoring force, such as a spring, is mounted.

The elastic member 1300 may be stretched or contracted as the cooling tip 2000 is mounted or detached from the cooling device 1000 .

For example, referring to FIG. 10 , when the cooling tip 2000 is mounted on the cooling device 1000 in the first direction along the central axis CA, the first elastic member 1310 and the second elastic member 1320 are can be stretched. Specifically, in a state in which one end of the first elastic member 1310 and the second elastic member 1320 is fixed to the coupling module 1200 with the elastic member fixing pin SP, the cooling tip 2000 is the cooling device 1000 . When mounted on the cooling module 1100 to which the other ends of the first and second elastic members 1310 and 1320 are fixed, the first elastic member 1310 and the second elastic member 1320 move in the first direction. ) may increase.

As another example, referring to FIGS. 9 and 10 , when the coupling member 1220 is separated from the cooling tip 2000 , the first elastic member 1310 and the second elastic member 1320 may contract. Specifically, in a state in which the first elastic member 1310 and the second elastic member 1320 are tensioned, the latch portion of the first coupling member 1221 and the second coupling member 1222 is separated from the groove of the cooling tip 2000 . When separated, the first elastic member 1310 and the second elastic member 1320 contract, and thereby the cooling module 1100 moves in the second direction, and the cooling tip 2000 may be separated from the cooling device 1000 . .

Here, the first direction means a proximal direction from the front end (F) of the cooling device 1000 toward the inside of the user or the cooling device 1000, and the second direction is the front end ( It may mean a distal direction toward F).

Meanwhile, the elastic member 1300 may provide an elastic force so that the cooling medium 1110 presses the contact member 2100 while the cooling tip 2000 is mounted on the cooling device 1000 . For example, as the cooling tip 2000 is mounted on the cooling device 1000, the elastic member 1300 is stretched as described above to provide an elastic force in the second direction and the cooling tip fixed by the coupling member 1220 ( 2000), the pressure due to the elastic force may be applied through the cooling medium 1110 in surface contact with the contact member 2100. At this time, as the cooling medium 1110 presses the contact member 2100 , interfacial thermal resistance or Kapitza resistance decreases, so that the cooling energy transfer efficiency from the cooling medium 1110 to the contact member 2100 is increased. can do. Here, the elastic force provided by the elastic member 1300 may be set to 0.1 MPa or more, 0.2 MPa or more, or 0.5 MPa or more depending on cooling efficiency.

On the other hand, in order to reduce the interfacial thermal resistance between the cooling medium 1110 and the contact member 2100 described above, a portion of the contact member 2100 in contact with the cooling medium 1110 is coated with a soft metal, such as a tin coating of 1 to 10 μm. may include

11 is a view illustrating the position movement of the cooling module 1200 as the cooling tip 2000 is mounted/removed from the cooling device 1000 according to an embodiment of the present specification.

The cooling module 1100 may move within the cooling device 1000 . For example, when the cooling tip 2000 is mounted on the cooling device 1000 in the first direction, the cooling module 1100 may also move in the first direction. Specifically, when the cooling tip 2000 is mounted on the cooling device 1000, the center, the center of gravity, or any point of the cooling module 1100 is constant in the first direction from the first position P1 on the central axis CA. It may move to a second location P2 separated by a distance. Here, all of the components of the cooling module 1100 such as the heat dissipation member 1140 including the heat dissipation fins and the heat pipe may be moved or only some may be moved. Also, here, the distance between the first position P1 and the second position P2 may be determined based on the degree of tension of the elastic member 1100 and the degree of protrusion of the cooling module 1100 from the cooling device 1000 . . For example, a distance between the first position P1 and the second position P2 may be determined within 1 to 5 mm.

On the other hand, one end connected to the coupling module 1200 among one end and the other end of the elastic member 1300 in order to move the cooling module 1100 as the cooling tip 2000 is mounted or detached from the cooling device 1000 is cooled. It may be located closer to the front end F of the cooling device 1000 than the other end fixed to the module 1100 . In other words, when the cooling tip 2000 is mounted on the cooling device 1000 in the first direction, the other end of the elastic member 1300 fixed to the cooling module 1100 capable of moving within the cooling device 1000 is cooled. One end of the elastic member 1300 fixed to the main body of the apparatus 1000 may be located at a predetermined distance in the first direction.

Also, the cooling module 1100 may include a plurality of ribs so that the cooling module 1100 can move within the cooling device 1000 . For example, a portion in contact with the temperature control member 1130 among the cooling medium 1110 , the cooling medium receiving member 1120 , the temperature control member 1130 , the tube and the heat dissipation member 1140 of the distal portion of the cooling module 1100 . The back is connected to and supported on the body part of the cooling device 1000 through the elastic member 1300, and the heat pipe and heat dissipation fins at the proximal part of the cooling module 1100 are attached to a plurality of ribs installed in the body part of the cooling device 1000. can be supported by

The cooling device 1000 may include an anti-collision area to prevent the cooling module 1100 from being damaged when the cooling module 1100 is moved within the cooling device 1000 .

Here, the collision avoidance region may mean a region between the rear end R of the cooling device 1000 and the cooling module 1100 in a state in which the cooling tip 2000 is separated from the cooling device 1000 . For example, referring back to FIG. 11 , the cooling device 1000 includes the output module 1700 at the rear end R, and the collision avoidance area is the area between the output module 1700 and the cooling module 1100 . can mean On the other hand, the collision avoidance area may be interpreted to mean the degree to which the cooling module 1100 is spaced apart from the rear end R of the cooling device 1000 . In addition, other components of the cooling device 1000 may not be disposed in the collision avoidance area.

The collision avoidance area may have a preset size. For example, when the cooling module 1100 moves from the first position P1 to the second position P2 as the cooling tip 2000 is mounted on the cooling device 1000, the central axis ( CA) direction length may be greater than or equal to the distance between the first location P1 and the second location P2. More specifically, when the cooling module 1100 is movable from the first position P1 to the second position P2, the heat pipe of the heat dissipation member 1140 is the output module (R) of the rear end of the cooling device 1000 ( The cooling module 1100 may be disposed in the cooling device 1000 to be spaced apart from the 1700 by a distance between the first location P1 and the second location P2 . At this time, when the cooling module 1100 moves by about 3 mm, the central axis CA direction length of the collision avoidance area may be greater than or equal to 3 mm.

Meanwhile, in order to protect the cooling module 1100 from external impact, the elastic member 1300 may provide elastic force in both directions. For example, the elastic member 1300 may include a compressible tension spring or a tensionable compression spring. Specifically, the elastic member 1300 may contract or stretch when an impact is applied to the cooling device 1000 in the central axis CA direction to alleviate the impact.

Hereinafter, the structure of the cooling tip 2000 will be described with reference to FIGS. 12 and 13 .

12 is a view showing the internal structure of the cooling tip 2000 and the cooling tip 2000 according to an embodiment of the present specification.

12 , the cooling tip 2000 may include a contact member 2100 and a tip body 2200 to which the contact member 2100 is mounted.

The contact member 2100 may include a locking portion 2110 for being mounted on the tip body 2200 . For example, the contact member 2100 is inserted into the opening 2210 of the tip body 2200, and the engaging portion 2110 of the contact member 2100 is in close contact with the engaging projection 2220 of the tip body 2200 to be described later. As the contact member 2100 and the tip body 2200 can be fixed by a press fit. At this time, the cooling medium 1110 presses the contact member 2100 by the elastic force of the elastic member 1300 so that the engaging portion 2110 of the contact member 2100 is on the engaging projection 2220 of the tip body 2200. could be more closely related.

The engaging portion 2110 of the contact member 2100 may be implemented in a shape to be mounted on the tip body 2200 . For example, the engaging portion 2110 of the contact member 2100 may have a tapered shape that becomes narrower in a direction in which the contact member 2100 is inserted into the tip body 2200 .

The tip body 2200 may include a groove 2230 for mounting in the cooling device 1000 and a locking protrusion 2220 for mounting the contact member 2100 . For example, referring back to FIG. 12 , a groove 2230 for engaging the coupling member 1220 of the cooling device 1000 is formed on the outside of the tip body 2200 , and the tip body 2200 is in contact with the inside. A locking jaw 2220 to which the locking portion 2110 of the member 2100 is in close contact may be formed.

The groove 2230 of the tip body 2200 will be omitted as described in detail above.

The locking jaw 2220 may be formed at a position spaced apart from one end of the tip body 2200 by a preset distance. For example, the locking jaw 2220 may be formed to be spaced apart from one end of the tip body 2200 by a distance shorter than the fourth length L4 of the contact member 2100 described above. At this time, the contact member 2100 is mounted to protrude from the tip body 2200, and may come into contact with the target surface before the tip body 2200 when cooling the target.

In the above, the case where the contact member 2100 is coupled, fixed, or mounted to the tip body 2200 in an interference fit manner has been mainly described, but the technical spirit of the present specification is not limited thereto, and the contact member 2100 and the tip It goes without saying that the body 2200 may be coupled by other mechanical methods such as adhesive bonding, magnetic bonding, or pin bonding.

At least a portion of the cooling module 1100 and the contact member 2100 may be inserted into the tip body 2200 . For example, referring back to FIG. 12 , the tip body 2200 includes a first internal space IS1 into which at least a portion of the cooling medium accommodating member 1120 is inserted, and a first inner space IS1 into which at least a portion of the contact member 2100 is inserted. 2 may include an internal space IS2.

Here, the first internal space IS1 may be implemented in a shape corresponding to the shape of the cooling medium accommodating member 1120 . For example, when the cooling medium accommodating member 1120 has a cylindrical shape having a third length L3 and a fourth width W4, the first internal space IS1 has a length shorter than the third length L3 and It may be implemented in a cylindrical shape having a width corresponding to the fourth width W4.

Here, the second inner space IS2 may be implemented in a shape corresponding to the shape of the contact member 2100 . For example, the second inner space IS2 may be implemented in a shape in which the width gradually increases in the direction in which the contact member 2100 protrudes based on the locking protrusion 2220 . At this time, since the side surface of the contact member 2100 does not come into contact with any portion other than the locking protrusion 2220 of the tip body 2200, cooling efficiency may be increased. In addition, an indentation mark formed on the surface of the target by the cooling tip 2000 may have a clear shape such as concentric circles.

Meanwhile, the first inner space IS1 and the second inner space IS2 may be divided based on the locking jaw 2220 , but the technical spirit of the present specification is not limited thereto.

13 is a view for explaining the shape of the cooling tip 2000 for marking the mark (indentation mark) (M) on the target surface according to an embodiment of the present specification.

Referring to FIG. 13 , at least a portion of the cooling tip 2000 may be implemented in a shape for forming a mark M on the surface of the target. Here, the mark M is displayed on the target surface by pressure as the cooling tip 2000 physically contacts the target surface, and may indicate the contact position of the cooling tip 2000 with respect to the target surface.

At least a portion of the tip body 2200 may include a protruding shape. For example, the tip body end 2240 may partially protrude to form a mark M on the target surface. Specifically, the tip body end 2240 may protrude in a ring shape or a dot shape to make a ring shape or a dot shape mark M on the surface of the target by pressure. The protruding shape of the tip body end 2240 may be variously implemented, such as a linear shape or a dotted line shape, in addition to the above-described ring shape or dot shape.

Tip body end 2240 may generally be configured as part of tip body 2200 . However, the tip body end 2240 may be configured to be separated from the tip body 2200 . In addition, the tip body end 2240 may be implemented with the same component or material as the tip body 2200 or may be implemented with a different component or material.

The tip body end 2240 for forming the mark M on the target surface may have a specific length. For example, as shown in FIG. 13 , the tip body end 2240 may extend by a sixth length L6 .

Here, the sixth length L6 may be set in consideration of the length of the contact member 2100 protruding from the tip body 2200 . For example, the sixth length L6 may be set such that the degree of protrusion when the contact member 2100 is inserted into the tip body 2200 is greater than or equal to that of the tip body end 2240 . In this case, when the cooling tip 2000 comes into contact with the target surface, the contact member 2100 contacts the target surface before or at the same time as the tip body end 2240, so that a mark M is formed on the target surface while maintaining cooling efficiency. can be For another example, the sixth length L6 may be set such that the protruding degree of the contact member 2100 from the tip body 2200 is smaller than the tip body end 2240.

Since the cooling tip 2000 has a specific shape, after cooling is performed on the target, a mark M is displayed on the surface of the target, so that the cooling area can be divided. In this way, by dividing a target or a region in which cooling is performed on the surface of the target, the portion where the next operation is to be performed may be clarified.

In the process of cooling the target using the cooling system 10 , there may be cases in which the treatment is performed in an unstable state or the target is damaged due to the characteristics of the target or the carelessness of the user. For example, if the cooling device 1000, which performs main cooling for a specific time by triggering, is driven before contacting the target surface through the cooling tip 2000, sufficient cooling of the target is not achieved, The operation may be performed while the target is not anesthetized. For another example, if the cooling device 1000 maintains contact with the target surface for an excessively long time, the target may be damaged by overcooling. As another example, since the cooling device 1000 does not contact the target with an appropriate pressure, sufficient cooling necessary for anesthesia may not be achieved, and also the target may be damaged by applying too strong pressure to the target.

According to an embodiment of the present specification, a safer and more detailed cooling control method may be provided to prevent the above-described problem from occurring in advance. For example, cooling including the process of determining whether the cooling performance conditions necessary for cooling the target are satisfied, such as whether the triggering or cooling device 1000 has made appropriate thermal contact with the target surface through the cooling tip 2000 A control method may be provided. For this cooling control method, it is possible to measure the time elapsed from the time when the thermal contact between the cooling tip 2000 and the target surface occurs, and through this, the cooling execution time for the target is limited to a specific time, and as a result, the target is supercooled. A cooling control method that excludes the case may be provided.

Hereinafter, a safe and detailed cooling control method using the cooling system 10 will be described with reference to FIGS. 14 to 17 .

14 is a diagram illustrating a temperature over time detected by the sensor module 1400 when a target is cooled by using the cooling control method according to an embodiment of the present specification.

Here, the temperature according to the time sensed by the sensor module 1400 may mean a temperature related to the target. For example, the temperature may mean the temperature of the cooling medium 1110 of the cooling module 1100 for cooling the target to a specific temperature. For another example, the temperature may mean the temperature of the contact member 2100 of the cooling tip 2000 . For another example, the temperature may mean a temperature at which the inside of the target or the surface of the target should be cooled. Hereinafter, for convenience of explanation, the case where the temperature measured by the sensor module 1400 over time is the temperature of the cooling medium 1110 is mainly described, but the technical spirit of the present specification is not limited thereto, and the sensor module 1400 ) may be similarly applied when the temperature measured at the contact member 2100 is the temperature of the contact member 2100 , the temperature inside the target, or the temperature of the target surface.

Referring to FIG. 14 , the cooling system 10 may control the temperature of the cooling medium 1110 during the first to fourth time periods T1 , T2 , T3 , and T4 . Hereinafter, each section will be described in detail.

In the first time period T1 , the cooling system 10 may prepare to cool the target. For example, the cooling device 1000 may control the temperature control member 1130 to allow the cooling medium 1110 of the first temperature C1 to reach the second temperature C2 .

Here, the first temperature C1 may mean the temperature of the cooling medium 1110 before the cooling system 10 operates. In this case, the length of the first time period T1 may be determined according to the first temperature C1 . For example, the first temperature C1 may be the same as room temperature, and in this case, power may not be supplied to the temperature control member 1130 . In another example, the first temperature C1 is lower than the room temperature, and the cooling system 10 controls the temperature control member 1130 to increase the temperature of the cooling medium 1110 before the first time period T1. It can be changed to temperature (C1). In this case, when the first temperature C1 is lower than the room temperature, the length of the first time period T1 may be shortened. On the other hand, the first temperature (C1) can be maintained higher than the dew point (Due point), thereby preventing moisture from forming on the cooling medium 1110, as a result, the length of the first time period (T1) is reduced, the user convenience can be increased. Specifically, when the temperature at room temperature is 25°C, when the first temperature C1 is set to 20°C, the length of the first time period T1 is reduced without moisture condensation in the cooling medium 1110, so that the user's waiting time This can be shortened.

Also, here, the second temperature C2 may refer to the ambient temperature before the cooling system 10 operates to perform cooling on the target. For example, the second temperature C2 may be set at 0°C to -20°C. Meanwhile, the difference between the first temperature C1 and the second temperature C2 may be greater than the difference between the second temperature C2 and a third temperature C3 to be described later.

The cooling system 10 controls the temperature of the cooling medium 1110 to the second temperature C2, which is the atmospheric temperature, in the first time period T1, so that the temperature of the cooling medium 1110 is adjusted according to the control of the cooling system 10. The time for changing to the target temperature for cooling, which will be described later, can be reduced, and on the other hand, compared to the target temperature, it is possible to reduce the discomfort experienced by the operator when contacting the target surface for cooling.

In the second time period T2 , the cooling system 10 may determine whether the cooling performance condition of the target is satisfied. For example, if the cooling system 10 maintains the temperature of the cooling medium 1110 at the second temperature C2 and the cooling performance condition for the target is satisfied, as will be described later, the target for the third time period T3. can be cooled.

The cooling performance condition may include a condition in which the cooling device 1000 receives a trigger signal. For example, the cooling performance condition may include a condition in which the cooling device 1000 receives a trigger signal from the input module 1600 . More specifically, when the control module 1800 of the cooling device 1000 receives a trigger signal by operating a trigger disposed outside the cooling device 1000 by the user, the control module 1800 determines that the cooling performance condition is satisfied. can do. Here, the trigger signal may mean a timer operation signal for instructing the user to operate the timer by pressing a trigger button configured as a switch mounted on the cooling device 1000 or by using a voice input or the like. Meanwhile, the timer may be used as a means for setting a cooling time to be described later, and may be used as a means for setting a specific new publication such as a waiting time and a trigger waiting time to be described in addition to that.

Alternatively, the cooling performance condition may include a condition in which the cooling tip 2000 contacts the target surface. For example, the control module 1800 obtains temperature information indicating the temperature of the cooling medium 1110 from the sensor module 1400, and based on the obtained temperature information, whether the cooling tip 2000 is in contact with the target surface It is determined whether the cooling tip 2000 is in contact with the target surface, it can be determined that the cooling performance condition is satisfied. As another example, the control module 1800 may obtain an electric signal related to the current or voltage of the cooling medium 1110 and determine whether a cooling performance condition is satisfied based on the obtained electric signal. As another example, the control module 1800 may determine whether a cooling performance condition is satisfied by using a touch sensor or a pressure sensor disposed adjacent to the cooling module 1100 . A method of determining whether the cooling tip 2000 or the cooling device 1000 equipped with the cooling tip 2000 in the cooling system 10 has contacted the target surface will be described in detail later.

Alternatively, the cooling performance condition may include a condition in which the cooling medium 1110 of the cooling device 1000 and the target are thermally coupled. For example, the control module 1800 obtains temperature information indicating the temperature of the cooling medium 1110 from the sensor module 1400, and based on the obtained temperature information, the cooling medium 1110 is connected to a target or a target surface and It may be determined whether or not thermally coupled, and if it is determined that the cooling medium 1110 is thermally coupled to the target or target surface, it may be determined that the cooling performance condition is satisfied.

On the other hand, the cooling performance condition may be configured by combining at least two or more of the above-described trigger signal reception condition, the cooling tip 2000, the contact condition of the target surface, and the thermal coupling condition. For example, the cooling performance condition may include a contact condition of the cooling tip 2000 and the target surface and a trigger signal reception condition. Specifically, when the contact condition is satisfied in the second time period T2 and the trigger signal reception condition is satisfied within a preset time, the cooling performance condition may be satisfied.

When the cooling performance conditions are a combination of different conditions, the second time period T2 may be divided into a plurality of time periods. For example, as shown in FIG. 15 , the second time period T2 may include a 2-1 time period T2-1 and a 2-2 time period T2-2. Specifically, the second time period T2 is a second-second period from the time when the temperature of the cooling medium 1110 reaches the second temperature C2 to the time when the contact condition of the cooling tip 2000 and the target surface is satisfied. It can be divided into one time period T2-1 and a second time period T2-2 from the time when the contact condition is satisfied to the time when the trigger signal reception condition is satisfied and all cooling performance conditions are satisfied. .

The temperature of the cooling medium 1110 may slightly change in the 2-1 time period T2-1 and the 2-2 time period T2-2. For example, when the cooling performance condition includes a contact condition or thermal coupling condition between the surface of the target and the cooling tip 2000 , the temperature of the cooling medium 1110 may increase as shown in FIG. 15 . The cooling device 1000 may determine whether a contact condition or a thermal coupling condition is satisfied through a temperature change of the cooling medium 1110 . The process of determining the cooling performance condition using the temperature change of the cooling medium 1110 will be described in detail later.

In the 2-1 time period T2-1 and the 2-2 time period T2-2, the cooling system 10 has a temperature control member ( 1130) can be controlled.

When there are a plurality of cooling performance conditions, the cooling system 10 may provide a notification to the user based on a time point when each cooling performance condition is satisfied. For example, as shown in FIG. 15 , the control module 1800 uses the output module 1700 to provide a second 'notification ( I2') can be provided. Specifically, when the control module 1800 detects that the cooling tip 2000 is in contact with the surface of the target as described later in the 2-1 time period T2-1, the cooling tip 2000 is the target to the user. It can provide a visual or audible notification indicating proper contact with the surface of the Here, when the cooling performance condition is satisfied in the second time period T2, each cooling execution condition is satisfied in the 2-1 time period T2-1 and the 2-2 time period T2-2 It may include cases where In other words, when the cooling performance condition is not satisfied in the second time section T2, when the cooling performance condition corresponding to the 2-1 time section T2-1 is not satisfied or the 2-1 time section ( It may include a case where the cooling performance condition corresponding to T2-1) is satisfied but the cooling performance condition corresponding to the 2-2 time period T2-2 is not satisfied.

On the other hand, if the above-described cooling performance condition is not satisfied in the second time period T2 , the cooling system 10 may stop or stop cooling the target. For example, the control module 1800 cools the cooling medium 1110 using the temperature control member 1130 when the cooling performance condition is not satisfied within the waiting time from the time when the temperature of the cooling medium 1110 reaches the second temperature C2. The temperature of the medium 1110 may be controlled to increase. As another example, when the cooling performance condition is not satisfied in the second time period T2 , the control module 1800 may turn off the power. As another example, when the cooling performance condition is not satisfied in the second time period T2 , the control module 1800 may not decrease the temperature of the cooling medium 1110 .

Here, the waiting time may be set within a preset safe time range to prevent damage to the target in advance. For example, the standby time may be set within 60 seconds to prevent overcooling of the target. Specifically, in a state in which the user brought the cooling tip 2000 into contact with the target surface, the cooling performance conditions such as receiving a trigger signal are not satisfied, so the contact between the cooling tip 2000 and the target surface continues, and accordingly damage to the target To prevent this from happening, the waiting time can be set to 5 seconds, 10 seconds, 20 seconds, 30 seconds, 45 seconds or 60 seconds, etc.

On the other hand, when there are a plurality of cooling performance conditions, if the cooling performance conditions are not satisfied in the 2-1 time period T2-1 or the 2-2 time period T2-2, the cooling system 10 is the target Cooling can be stopped or stopped. For example, the control module 1800 controls the temperature if the contact condition of the cooling tip 2000 and the target surface is not satisfied within the contact waiting time from the time when the temperature of the cooling medium 1110 reaches the second temperature C2. By using the member 1130, the temperature of the cooling medium 1110 may be controlled to increase or the power may be turned off. For another example, the control module 1800 uses the temperature control member 1130 to control the cooling medium if the trigger signal reception condition is not satisfied within the trigger waiting time from the time when the contact condition of the cooling tip 2000 and the target surface is satisfied. The temperature of 1110 may be controlled to increase or the power may be turned off.

Here, the contact waiting time may be set to a time suitable for the user to contact or thermally couple the cooling tip 2000 to the surface of the target. For example, the contact waiting time may be set within 60 seconds. More preferably, the contact waiting time may be set to 5 seconds, 7 seconds, 10 seconds, 15 seconds, 20 seconds, 30 seconds or 45 seconds. On the other hand, even if it is not determined that the contact condition is satisfied even though the cooling tip 2000 has contacted the surface of the target due to a failure or malfunction of the cooling system 10, the contact standby time is set to be short as described above, so that the target Overcooling can be prevented.

Also, here, the trigger waiting time may be set in the overcooling prevention time range to prevent the cooling tip 2000 from contacting or thermally coupled to the surface of the target for too long. For example, the trigger waiting time may be set within 30 seconds. More specifically, the trigger waiting time may be set to 5 seconds, 10 seconds, or 15 seconds. The trigger waiting time may be set shorter than the contact waiting time. By setting the trigger waiting time to be sufficiently short in this way, it is possible to limit the actual time that the target is cooled by the cooling tip 2000 , and as a result, it is possible to prevent the target from being excessively cooled by the cooling system 10 .

The safety time range or the overcooling prevention time range is not limited to the above-described ones and may be set variously. For example, the safe time range or the overcooling prevention time range may be set within a time limit for which reversible damage to the target occurs as cooling continues.

As described above, the cooling system 10 can more safely cool the target by determining whether the cooling performance condition is satisfied in the second time period T2, and the cooling performance condition is not limited to the above-described conditions, of course. to be.

In the third time period T3 , the cooling system 10 may perform main cooling of the target. For example, the cooling system 10 may change and maintain the temperature of the cooling medium 1110 to the third temperature C3 .

Here, the third temperature C3 may mean a target temperature for the target to become anesthetized or pain-free as cooling of the target is performed. For example, the third temperature C3 may be set at -60°C to -5°C. In this case, the third temperature C3 may be set equal to or smaller than the second temperature C2.

In the third time period T3 , the cooling system 10 may perform cooling of the target during the cooling time. Here, the length of the cooling time may be set in a range in which a cooling anesthetic effect on the target occurs. For example, the length of the cooling time may be set between 5 seconds and 20 seconds. In another example, when the cooling system 10 performs cooling for other purposes such as cooling treatment in addition to cooling anesthesia, the third time period T3 may be set to be longer than 20 seconds.

In the third time period T3 , the cooling system 10 may provide a notification to the user. For example, as shown in FIG. 14 , the control module 1800 may provide a third notification I3 indicating that the third time period T3 has started to the user through the output module 1700 . In addition, the control module 1800 may provide a fourth notification I4 indicating that it is in the middle of the third time period T3 to the user through the output module 1700 .

The cooling system 10 cools the target by controlling the temperature of the cooling medium 1110 to the target temperature during the cooling time in the third time period T3, whereby the target may be in an anesthetic state or an analgesic state.

In the fourth time period T4 , the cooling system 10 may control the temperature of the cooling medium 1110 to separate the cooling device 1000 from the target surface. For example, when the cooling device 1000 is separated from the target surface, the cooling system 10 may include a cooling medium ( The temperature of 1110 may be changed to the fourth temperature C4 .

Here, the fourth temperature (C4) may mean a safe temperature for preventing an ice adhering phenomenon between the cooling tip 2000 and the target. For example, the fourth temperature C4 may be set between -10°C and 10°C.

The cooling system 10 is cooled to the target by changing the temperature of the cooling medium 1110 to the fourth temperature C4 in the fourth time period T4, and the cooling tip 2000 or the cooling device 1000 from the target surface after cooling. can be safely separated. For example, the cooling system 10 may control the temperature adjusting member 1130 so that the temperature of the cooling medium 1110 becomes the fourth temperature C4 at a constant rate or a variable rate during the separation preparation time. At this time, the cooling system 10 indicates that the temperature of the cooling medium 1110 has reached the fourth temperature C4 or the fifth notification indicating that the cooling tip 2000 can be safely separated from the surface of the target. (I5) can be provided. Here, the fifth notification I5 may be provided even when the cooling system 10 stops cooling according to satisfaction of a specific condition in the cooling process for the target or the user stops cooling by manipulating the cooling device 1000 . . Specifically, when the user stops cooling due to an emergency situation while performing cooling on the target, when the temperature of the cooling medium 1110 reaches the fourth temperature C4, the cooling system 10 provides a fifth notification I5. can provide According to the provision of the fifth notification I5, the user can safely separate the cooling tip 2000 from the surface of the target.

The fourth time period T4 may be distinguished from the third time period T3 . For example, the cooling device 1000 may drive different timers in the third time period T3 and the fourth time period T4 . Specifically, the cooling device 1000 drives a timer set as a cooling time in the third time period T3 to control the temperature of the cooling medium 1110 to be maintained at a target temperature during the cooling time, and cools after the timer ends. It is possible to control the temperature of the medium 1110 to be changed to a safe temperature. In other words, the cooling device 1000 may not include a control for changing the temperature of the cooling medium 1110 to a safe temperature in the third time period T3, thereby ensuring sufficient time for cooling the target. can be

Meanwhile, in the above description, for convenience of explanation, the first to fourth temperatures (C1, C2, C3, C4) have been described as indicating a specific temperature selected within a specific range, but the technical spirit of the present specification is not limited thereto . For example, the first to fourth temperatures (C1, C2, C3, C4) may indicate within an error range (ex. ±5°C) based on a specific temperature selected within each of the above-described temperature ranges. . As another example, the first to fourth temperatures C1 , C2 , C3 , and C4 may indicate a temperature range selected within each of the above-described temperature ranges.

The aforementioned waiting time, contact waiting time, trigger waiting time, cooling time, and separation preparation time may be set within an appropriate range to prevent damage to the target due to cooling to the target. For example, in the second time period T2 and the third time period T3 , the cooling system 10 may provide cooling energy to the target during the standby time and the cooling time, so that the sum of the standby time and the cooling time is preset It can be set within a set time range. Specifically, the standby time and the cooling time may be set so that the sum thereof is within 60 seconds, and more preferably, it may be set within 15 seconds to 30 seconds.

Similarly, when there are a plurality of cooling performance conditions, the cooling system 10 may provide cooling energy to the target during the 2-2 time period T2-2 and the cooling time, so the sum of the trigger waiting time and the cooling time is It may be set within a preset time range. Specifically, the trigger standby time and the cooling time may be set so that the sum thereof is within 60 seconds, and more preferably, it may be set within 15 seconds to 30 seconds. Furthermore, the sum of the contact standby time, the trigger standby time, and the cooling time may be set to be within 60 seconds.

As another example, the total sum of the standby time, the cooling time, and the separation preparation time, which is the time required for cooling the target, may be set to be within 60 seconds.

As another example, when the cooling system 10 is used for the purpose of selectively destroying or treating a target other than cooling anesthesia, the sum of the waiting time and the cooling time may be set to 60 seconds or more.

Meanwhile, the cooling system 10 may provide a notification to inform the user of a start time, a progress time, or an end time of the first to fourth time periods T1 , T2 , T3 , and T4 . Alternatively, a notification may be provided to inform the user of the start time, progress time, or end time of the cooling system 10 , the 2-1 and 2-2 time sections T2-1 and T2-2. For example, referring back to FIG. 14 , the cooling device 1000 may provide the first to fifth notifications I1 , I2 , I3 , I4 , and I5 to the user using the output module 1700 . For another example, as shown in FIG. 15 , the cooling device 1000 adds a second 'reminder (I2') to the user in addition to the first to fifth notifications (I1, I2, I3, I4, I5). can provide The notification provided to the user during the cooling process will be described in detail later.

16 and 17 are views illustrating a cooling control method according to an embodiment of the present specification.

16 and 17 , the cooling control method includes the steps of providing a first notification I1 ( S1100 ), controlling the temperature of the cooling medium 1110 to be the standby temperature ( S1200 ), and cooling second notification Providing (I2) (S1300), maintaining the temperature of the cooling medium 1110 at the standby temperature during the standby time (S1400), determining whether the cooling performance condition is satisfied within the standby time (S1500), It may include stopping cooling (S1600) and performing main cooling (S2000).

Hereinafter, each step will be described in detail. However, portions overlapping with those described above with reference to FIG. 14 will be omitted.

The cooling system 10 may provide a first notification I1 to the user (S1100). Here, the first notification I1 may include a notification instructing the start of preliminary cooling. For example, when the user drives the cooling device 1000 such as by turning on the power of the cooling device 1000 or pressing a cooling start button, the control module 1800 performs the first operation through the output module 1700 . A notification I1 can be output. The user can recognize through the first notification I1 that the cooling module 1100 of the cooling device 1000 operates and the temperature control member 1130 controls the temperature of the cooling medium 1110 to be the standby temperature. .

The cooling control method may further include the step of checking whether the cooling tip 2000 is reused before, after, or simultaneously with the step of providing the first notification I1 to the user.

As an example, the cooling system 10 may inquire whether the cooling tip 2000 is reused before providing the first notification I1 to the user. Specifically, the cooling system 10 inquires whether the cooling tip 2000 mounted on the cooling device 1000 is reused to the user through a visual or audible notification, and based on the user's response, the cooling tip 2000 ) is not to be reused, the first notification I1 may be provided and steps described below may be performed. Here, the user's response may be made through a cooling start button input, a trigger button input, a voice input, etc. included in the cooling device 1000 .

As another example, the cooling system 10 may determine whether to reuse by acquiring information on whether to reuse or not from a storage box or capsule storing the cooling tip 2000 . Specifically, the cooling device 1000 determines whether the cooling tip 2000 is a new product by recognizing a barcode printed or attached to the sealing member sealing the cooling tip 2000, or at least of the cooling tip 2000. It is determined whether a part is damaged to determine whether the cooling tip 2000 is reused, and if it is determined that the cooling tip 2000 is not to be reused, a first notification I1 may be provided and the steps described below may be performed. .

The cooling system 10 may control the temperature of the cooling medium 1110 to be the atmospheric temperature (S1200). A description of the method in which the temperature of the cooling medium 1110 is changed to the ambient temperature is the same as that described in other parts of the present specification, and thus will be omitted.

The cooling system 10 may provide a second notification I2 to the user (S1300). Here, the second notification I2 may include a notification indicating that the temperature of the cooling medium 1110 reaches the atmospheric temperature. For example, the control module 1800 may provide the second notification I2 through the output module 1700 when the temperature information of the cooling medium 1110 obtained from the sensor module 1400 indicates the ambient temperature. have. The user may recognize that the cooling device 1000 is in a state capable of contacting the target surface through the second notification I2 and may bring the cooling device 1000 into contact with the target surface.

The cooling system 10 may maintain the temperature of the cooling medium 1110 at the ambient temperature (S1400). For example, the control module 1800 maintains the temperature of the cooling medium 1110 at the standby temperature for a preset standby time (eg, 20 seconds) from the time when the temperature of the cooling medium 1110 reaches the standby temperature. The temperature control member 1130 may be controlled so as to be possible. At this time, as will be described later, when the standby time elapses without any action from the user, the cooling function may be stopped or stopped, so the control module 1800 may provide an additional notification to the user before the elapse of the standby time.

The cooling system 10 may determine whether a cooling performance condition is satisfied within the standby time (S1500). A description of the cooling performance condition and the method for determining whether the cooling system 10 satisfies the cooling performance condition within the standby time is the same as described in other parts of the present specification, and thus will be omitted.

The cooling system 10 may stop cooling when the cooling performance condition is not satisfied within the standby time (S1600). For example, the control module 1800 may stop cooling the target when the cooling performance condition is not satisfied within the standby time after the temperature of the cooling medium 1110 becomes the standby temperature. Specifically, the control module 1800 may control the temperature control member 1130 to increase the temperature of the cooling medium 1110 or to turn off the power of the cooling device 1000 . When the cooling system 10 is not satisfied with the cooling performance condition within the standby time, damage to the target can be prevented by stopping the cooling of the target.

Meanwhile, the cooling system 10 may operate a timer for cooling the target according to the satisfaction of the cooling performance condition. For example, the control module 1800 operates a timer set to a specific time when receiving a trigger signal or the cooling tip 2000 comes into contact with the target surface, and the control module 1800 operates the timer set to the target when the timer expires. cooling can be stopped. Here, the specific time set by the timer may be a cooling time described in another part of this specification or may be set within a safe time range. By independently driving the timer according to the satisfaction of the cooling performance condition in the cooling system 10 , damage to the target due to overcooling can be prevented.

Here, when there are a plurality of conditions for performing cooling, one cooling condition may take precedence over another condition for performing cooling, and the cooling system 10 may operate at least one timer.

For example, when the cooling performance condition includes a trigger signal reception condition and a contact condition of the cooling tip 2000 and the target surface, the contact condition may take precedence over the trigger signal reception condition.

For example, the cooling performance condition may be satisfied only when the trigger signal reception condition is satisfied within a preset time or trigger waiting time after the contact condition is satisfied. Specifically, when the cooling tip 2000 contacts the target surface within the standby time in a state where the temperature of the cooling medium 1110 reaches the standby temperature, the timer operates for a preset time (eg, trigger standby time) and , when the control module 1800 receives a trigger signal before the timer ends, the temperature of the cooling medium 1110 is changed and maintained to the target temperature, and if the control module 1800 does not receive the trigger signal before the timer ends, the Cooling may be interrupted.

For another example, if the trigger signal reception condition is satisfied after the trigger waiting time elapses after the touch condition is satisfied, the control module 1800 operates the timer when the contact condition is satisfied and does not operate the timer newly or separately even if the trigger signal reception condition is satisfied The timer may not work. Alternatively, if the contact condition is satisfied after the trigger signal reception condition is satisfied, the control module 1800 operates a timer when the trigger signal reception condition is satisfied, and operates a new timer or operates a separate timer when the contact condition is satisfied to prevent the contact condition satisfaction. When the corresponding timer operation is completed, cooling of the target may be stopped.

As another example, in the above example, the trigger signal reception condition may partially take precedence over the contact condition. Specifically, when the trigger signal reception condition is satisfied after the touch condition is satisfied, the control module 1800 may operate a timer when the contact condition is satisfied and may operate a new timer or operate a separate timer when the trigger signal reception condition is satisfied. Alternatively, the control module 1800 may stop cooling the target when the contact condition within the waiting time is satisfied but the trigger signal reception condition is not satisfied.

Meanwhile, when there are a plurality of cooling conditions, the cooling control method may further include determining whether the cooling conditions are satisfied and additional notification steps. For example, referring to FIG. 17 , the cooling control method includes the step of determining whether the contact condition within the contact waiting time is satisfied (S1510) instead of the step of determining whether the cooling performance condition is satisfied within the waiting time (S1500) ), providing a second' notification I2' and determining whether a trigger signal reception condition is satisfied within the trigger waiting time (S1530) may be further included. Here, for convenience of explanation, it is mainly described that a case in which a plurality of cooling conditions are performed is a case in which the trigger signal reception condition is satisfied after the condition that the cooling tip 2000 contacts the target surface is satisfied. It is not limited.

The cooling system 10 determines whether the contact condition is satisfied within the contact waiting time (S1510), and when the contact condition is satisfied, provides a second 'notification (I2') (S1520), trigger signal reception condition within the trigger waiting time (S1520) It is determined whether or not it is satisfied (S1530), and when the trigger signal reception condition is satisfied, main cooling of the target may be performed as described below (S2000). Here, if the contact condition is not satisfied within the contact waiting time or the trigger signal reception condition is not satisfied within the trigger waiting time, the cooling system 10 may stop cooling ( S1600 ). When there are a plurality of conditions for performing cooling, the detailed description of the cooling control method will be omitted as described in other parts of the present specification. The cooling system 10 may perform main cooling of the target when the cooling performance condition is satisfied (S2000). Referring back to FIG. 18, the step (S2000) of the cooling system 10 performing main cooling on the target is the step of providing a third notification (I3) (S2100), the temperature of the cooling medium 1110 during the cooling time It may include changing and maintaining the temperature to the target temperature (S2200) and changing the temperature of the cooling medium 1110 to a safe temperature (S2300).

Hereinafter, each step of the main cooling performing step (S2000) will be described in detail.

The cooling system 10 may provide a third notification I3 to the user. Here, the third notification I3 may include a notification indicating that the cooling performance condition is satisfied within the waiting time or the trigger waiting time to perform the main cooling. For example, the control module 1800 receives a trigger signal within a standby time or a trigger standby time after the temperature of the cooling medium 1110 reaches the standby temperature, or receives temperature information or an electrical signal obtained from the sensor module 1400 . When it is determined that the cooling tip 2000 is in contact with the target surface based on it, a third notification I3 may be output through the output module 1700 . The user may recognize that the cooling tip 2000 is in contact with the target surface or the start of main cooling for the target through the third notification I3.

The cooling system 10 may change and maintain the temperature of the cooling medium 1110 to the target temperature during the cooling time ( S2200 ). For example, the control module 1800 may change and maintain the temperature of the cooling medium 1110 to a target temperature for a cooling time from a time when the cooling performance condition is satisfied. In this case, the control module 1800 may provide a fourth notification I4 indicating that the target is being cooled to the user according to the time during which the main cooling is performed. Specifically, the control module 1800 may provide a notification to the user when the cooling time has elapsed in half and when both the cooling time has elapsed. Alternatively, the control module 1800 may provide a notification to the user every predetermined time (eg, 5 seconds).

The cooling system 10 may change the temperature of the cooling medium 1110 to a safe temperature (S2300). For example, the control module 1800 may control the temperature adjusting member 1130 so that the temperature of the cooling medium 1110 becomes a safe temperature. In this case, when the temperature of the cooling medium 1110 reaches a safe temperature, the control module 1800 may provide a fifth notification I5 informing the user that the separation of the target and the cooling device 1000 is safe.

Meanwhile, the cooling control method may include a pause step. For example, the cooling system 10 may stop the cooling control method when a temporary stop condition is satisfied while at least one of the steps included in the above-described cooling control method is performed. Specifically, when the cooling device 1000 receives a control signal corresponding to a cooling start button or a trigger button or receives a specific user voice signal while the cooling control method is being performed, the power provided to the temperature control member 1130 is cut off Alternatively, the temperature of the cooling medium 1110 may be increased by using the temperature control member 1130 . At this time, when the temperature of the cooling medium 1110 reaches a safe temperature, the cooling device 1000 may provide a notification indicating that the cooling tip 2000 can be safely separated from the target surface to the user. Through such an instant pause function, the user can quickly detach or remove the cooling device 1000 or the cooling tip 2000 equipped with the cooling tip 2000 from the target surface, at this time the above-described coupling module 1200. Latch coupling of can be utilized.

The first to fifth notifications I1, I2, I2', I3, I4, and I5 may include various types of notifications. For example, the first to fifth notifications I1, I2, I2', I3, I4, and I5 are a visual notification such as LED blinking, a display output, etc., an audible notification such as a beep or voice output, respectively, and It may include at least one of tactile notifications such as micro vibrations. Also, the first to fifth notifications I1, I2, I2', I3, I4, and I5 may be implemented in the same or different manners. Also, the first to fifth notifications I1, I2, I2', I3, I4, I5 may be temporary or continuous for at least a portion of the corresponding time interval.

Hereinafter, a method for determining whether the cooling tip 2000 is in contact with the target surface will be described with reference to FIG. 19 .

19 is a view for explaining a method of determining whether the cooling tip 2000 is in contact with the target surface according to an embodiment of the present specification.

Referring to FIG. 19 , the cooling system 10 determines whether the cooling device 1000 equipped with the cooling tip 2000 is in contact with the target surface based on sensing information obtained from the sensor module 1400 . can do.

For example, whether the cooling tip 2000 and the target surface are in contact may be determined based on the change amount of the temperature of the cooling medium 1110 over time.

For example, if the instantaneous change amount (= dT/dt) of the temperature of the cooling medium 1110 obtained from the sensor module 1400 is equal to or greater than a preset value, the control module 1800 determines that the cooling tip 2000 has contacted the target surface. can judge Referring back to FIG. 19 , when the cooling tip 2000 does not contact the target surface, the instantaneous change in the temperature of the cooling medium 1110 does not exceed the reference value, and when the cooling tip 2000 comes into contact with the target surface, the body heat Accordingly, the temperature value of the cooling medium 1110 may increase instantaneously, and the instantaneous change amount of the temperature of the cooling medium 1110 may exceed the reference value.

Here, the control module 1800 may acquire the instantaneous change amount of the temperature of the cooling medium 1110 based on the temperature information of the cooling medium 1110 obtained from the sensor module 1400 at different time points. For example, the following equation (1) may be used.

Here, grad(i) refers to the instantaneous change amount of the temperature of the cooling medium 1110, data(i) refers to the temperature value of the cooling medium 1110 at an arbitrary first time point (time(i)), and data (i+1) may mean a temperature value of the cooling medium 1110 at a second time point (time(i+1)) after the first time point. The control module 1800 may further use the following equation in obtaining the instantaneous change amount of the temperature of the cooling medium 1110 .

Here, data (i-1) means the temperature value of the cooling medium 1110 at the third time point before the first time point, and w is selected from 0 to 1 as a weight to correct the temperature value of the cooling medium 1110 can do.

For another example, the control module 1800 controls the cooling tip 2000 when the temperature change amount, which is the difference in the temperature value of the cooling medium 1110 at any first time point and the second time point thereafter, is equal to or greater than a preset value, the cooling tip 2000 is the target surface It can be concluded that contact with

As another example, the control module 1800 may determine that the cooling tip 2000 has contacted the target surface when the instantaneous change amount or the temperature change amount of the temperature of the cooling medium 1110 in an arbitrary time interval is greater than or equal to a preset value. .

As another example, when the temperature of the cooling medium 1110 exceeds a preset value, the control module 1800 may determine that the cooling tip 2000 has contacted the target surface.

As another example, the control module 1800 determines that the cooling tip 2000 is the target surface when the value obtained by integrating the area of the function with respect to the time of the temperature change rate, that is, grad * time in FIG. 19, exceeds a preset value. It can be concluded that contact with

As another example, in order to more precisely determine whether a contact is made, a control with relatively high temperature precision may be used during a waiting time or a trigger waiting time to be described later. For example, the above-described PID control may be used. Specifically, the Cp, Ci, and Cd constant values may be different from other sections, and more specifically, the Cd value may be set relatively large. As another example, power having a constant value may be applied to the temperature control member 1130 during the standby time or the trigger standby time. Specifically, an average value of the power P(t) applied to the cooling medium 1110 through PID control for a predetermined time may be calculated, and the average value may be applied to the temperature control member 1130 for a standby time or a trigger standby time.

Meanwhile, whether the cooling tip 2000 and the target surface are in contact may be determined based on the temperature of each part of the cooling medium 1110 . Specifically, as long as the cooling medium 1110 has a certain volume, as the cooling tip 2000 contacts the target surface, the temperature of a portion relatively close to the target surface and a portion relatively far from the target surface of the cooling medium 1110 changes differently It can be done, and whether the cooling tip 2000 and the target surface are in contact can be determined by using the temperature change for each part of the cooling medium 1110 .

For example, whether to contact may be determined based on a temperature of a portion of the cooling medium 1110 that is close to the cooling tip 2000 and a temperature of a portion of the cooling medium 1110 that is close to the temperature control member 1130 . Specifically, a first temperature value obtained from a sensor disposed in a first area close to the cooling tip 2000 of the cooling medium 1110 and disposed in a second area close to the temperature control member 1130 of the cooling medium 1110 When the difference between the second temperature value obtained from the sensor meets a preset range, when the difference between the first instantaneous change amount of the first temperature value and the second instantaneous change amount of the second temperature value satisfies the preset range, Alternatively, when the value of the base area over time of the difference between the rate of change of the first temperature value and the rate of change of the second temperature value satisfies a preset range, it may be determined that the cooling tip 2000 and the target surface are in contact. Here, the above-described calculation process may be used in deriving the temperature value for each part of the cooling medium 1110 or the instantaneous change amount of the temperature value.

As described above, in order to determine whether the cooling tip 2000 and the target surface are in contact using the temperature of each part of the cooling medium 1110, the cooling device 1000 measures the temperature in different parts of the cooling medium 1110. It may include a plurality of temperature sensors. For example, the cooling device 1000 may include a first temperature sensor disposed at a preset distance from one end of the cooling medium 1110 and a first temperature sensor spaced apart from the first temperature sensor by a preset distance along the central axis of the cooling medium 1110 . A second temperature sensor may be included. For another example, the cooling device 1000 is disposed adjacent to the temperature control member 1130 to measure a temperature of at least a portion of the cooling medium 1110 and a third temperature sensor and a temperature control member (rather than the third temperature sensor) A fourth temperature sensor disposed far from 1130 to measure the temperature of at least a portion of the cooling medium 1110 may be included.

On the other hand, in the above, it is determined whether the cooling tip 2000 and the target surface are in contact based on the temperature of the cooling medium 1110, but the technical idea of the present specification is not limited thereto, and the temperature of the cooling tip 2000 or the target surface It may be determined whether the target surface and the cooling tip 2000 are in contact based on the temperature of

As another example, whether the cooling tip 2000 and the target surface are in contact may be determined based on a change in electrical properties of the cooling medium 1110 . Specifically, the control module 1800 or the sensor module 1400 includes a circuit electrically connected to the cooling medium 1110, and the control module 1800 operates the cooling medium 1110 at an arbitrary time point and before or after. ) or from the sensor module 1400 to obtain information such as the current, voltage, or power value of the cooling medium 1110, and when the amount of change in the current, voltage or power value of the cooling medium 1110 is greater than a certain value, the cooling tip (2000) ) can be determined to be in contact with the target surface.

As another example, in order to determine whether the cooling tip 2000 and the target surface are in contact, the sensor module 1400 includes a touch sensor, and the control module 1800 uses the touch sensor to determine whether the cooling tip 2000 and the target surface are in contact. It can be determined whether or not the Here, the touch sensor may include a capacitive touch sensor or a pressure-sensitive touch sensor that detects a change in capacitance.

As another example, whether the cooling tip 2000 and the target surface are in contact may be determined based on the pressure received by the cooling device 1000 . Specifically, the sensor module 1400 includes a pressure sensor, and the control module 1800 obtains pressure information indicating a pressure value applied to the cooling module 1100 from the sensor module 1400, and the pressure value is preset. If the set value is exceeded, it may be determined that the cooling tip 2000 has contacted the target surface. Furthermore, when the pressure value obtained from the pressure sensor is in a safe range in which the target is not damaged or exceeds a pressure value causing damage to the target, the cooling device 1000 may provide a safety notification or a danger notification, respectively, to the user. have.

The cooling system 10 may provide a notification to the user when the cooling tip 2000 and the target surface come into contact and may trigger a timer set to the cooling time. Alternatively, when a trigger signal is received within a preset trigger waiting time when the cooling tip 2000 and the target surface come into contact, the cooling device 1000 may provide a notification to the user and operate a timer set for the cooling time.

In the above, the case where the cooling tip 2000 contacts the target surface has been mainly described, but the technical spirit of the present specification is not limited thereto. For example, the above description may be similarly applied when the cooling medium 1110 is in contact with the target surface or when the cooling medium 1110 is thermally coupled to the target surface.

Meanwhile, in order to quickly and accurately determine whether the cooling tip 2000 and the target surface are in contact, sensing information of the sensor module 1400 must be accurately and quickly acquired. Hereinafter, an arrangement position of the sensor module 1400 for quickly and accurately acquiring sensing information will be described.

20 is a view for explaining a method in which the sensor module 1400 is disposed in the cooling device 1000 according to an embodiment of the present specification. Hereinafter, a case in which the sensor module 1400 is a temperature sensor inserted into the cooling medium 1110 is mainly described for convenience of description, but the technical spirit of the present specification is not limited thereto.

Referring to FIG. 20 , the sensor module 1400 may be inserted into the cooling medium 1110 and provide temperature information obtained by sensing the temperature of the cooling medium 1110 to the control module 1800 . For example, the sensor module 1400 is disposed in the cooling medium 1110 such that the distance between the sensing part for sensing the temperature of the sensor module 1400 and one end of the cooling medium 1110 becomes a preset separation distance D. can be

Here, the sensing part may refer to a part in which at least a part of the cooling medium 1110 is in contact or non-contact to obtain the temperature information of the cooling medium 1110 .

Here, the separation distance D may mean a distance from one end of the cooling medium 1110 to the center of the sensing part of the sensor module 1400 or one end of the sensing part.

The separation distance D may be set such that the sensing portion of the sensor module 1400 is sufficiently close to the target surface. For example, referring back to FIG. 20 , the separation distance D may be set equal to or shorter than the second length L2 of the protruding portion of the cooling medium 1110 . For another example, the separation distance (D) is set shorter than the fourth length (L4) of the contact member (2100) of the cooling tip (2000), or the tip body ( 2200) may be set to less than or equal to the fifth length L5. More specifically, the separation distance D may be set within 10 mm. In this case, in order to minimize the distance between the center of the sensing portion and the target surface, the thickness of the contact member 2100 in the separation distance D direction may be 1 mm or less.

The separation distance D may be set in consideration of the partial heat capacity of the cooling medium 1110 . For example, referring back to FIG. 20 , the separation distance D may be divided into a first part R1 and a second part R2 with the cooling medium 1110 as the center of the sensing part of the sensor module 1400 . In this case, the heat capacity of the first portion R1 may be set to be smaller than the heat capacity of the second portion R2 . Specifically, the separation distance D may be set such that the mass of the first part R1 is smaller than the mass of the second part R2 . Alternatively, the specific heat of the first portion R1 may be smaller than the specific heat of the second portion R2 . Here, with reference to the plane perpendicular to the central axis CA and including the center of the sensing part, the portion close to the target surface during the procedure among the cooling medium 1110 is the first portion R1, and the portion farther from the target surface is the second It may be interpreted as the part R2, but the technical spirit of the present specification is not limited thereto. On the other hand, the heat capacity of the contact member 2100 of the cooling tip 2000 may be set to be smaller than the heat capacity of the first portion (R1). Alternatively, the mass of the contact member 2100 of the cooling tip 2000 may be 1 g or less, and more specifically, may be set to 0.5 g or less.

As described above, as the separation distance D is set, the temperature of the cooling medium 1110 , which is one of the main elements of target cooling in the cooling system 10 , can be precisely controlled, and the temperature change of the cooling medium 1110 . It is possible to quickly and accurately determine whether the cooling tip 2000 and the target surface are in contact with each other by quickly detecting , thereby increasing the cooling efficiency and safety of the cooling system 10 .

In order to safely cool the target in the cooling system 10, the cooling tip 2000 is disposable and may be replaced for every procedure or treatment. At this time, when the user uses the cooling system 10 for a procedure or treatment, a plurality of cooling tips 2000 are safely stored and the user can easily mount the cooling tips 2000 to the cooling device 1000 . A tip holder 4000 is required.

Hereinafter, the tip storage box 4000 for storing the cooling tip 2000 described above with reference to FIGS. 21 and 22 will be described.

21 is a view showing a tip storage box 4000 according to an embodiment of the present specification. Referring to FIG. 21 , the tip storage box 4000 may include a case 4100 and a storage member 4200 .

A storage member 4200 may be disposed in the case 4100 .

The case 4100 may be implemented as portable, including a cover, and preferably has a rectangular parallelepiped shape, but the technical spirit of the present specification is not limited thereto, and may have various shapes.
