{COOL BAND USING COLDNESS-STORED MATERIAL}

[0001] The present invention relates to a cooling band using a cooling material, and more particularly, to a cooling band using a cooling material which can be wound around a body part requiring a cold feeling even when the cooling material is frozen, It is about the band.

Generally, ice scarves are used to prevent the occurrence of adverse effects due to deterioration of work efficiency and physiological change due to unpleasantness in case of hot phenomenon which can not cope with heat due to hot heat in a hot summer outdoor work or a workplace of various industrial sites It serves to cool the heat for a long time.

The conventional ice muffler adopts a method of forming a cold storage space in a muffler and putting a cold storage material therein to make it feel cool. However, depending on the structure of the freezing material, the shape of the freezing material changes when it is frozen.

According to Korean Utility Model Registration Application No. 20-1999-0013059, a method is employed in which a shaft-shaped cold storage space is formed in a scarf (a muffler is referred to as a scarf), and a liquid-state cold storage material is inserted as it is. In this case, since the liquid coolant is directly put into the muffler without protective device, the coolant liquid is leaked out and it is inconvenient to use. If it is frozen, the desired shape can not be maintained.

According to Korean Utility Model Registration Application No. 20-2007-0010171, water, phase change material (PCM), water absorbent polymer, 2-hydroxypropanol, However, in the case where the ice pack for accommodating the ice cream pack is made of a single mass, it is difficult to have a shape corresponding to the body part and to be frozen, and the ice cream is not easily folded or bent when it is frozen.

According to Korean Patent Application No. 10-2008-0099920, the axial coolant is stored in a plurality of compartments connected in series so that the axial coolant pack can be bent easily. However, in such a cold storage material pack, the capacity of the cold storage material is reduced and the time for maintaining the cold energy is reduced. Since the heat loss rates of the compartments in the portions not touching the body are different from each other and heat exchange between the compartments is not performed, The heat distribution of the cold pack becomes uneven and the use efficiency is lowered. In addition, there is a problem in that the heat-loss is caused in the outer portion other than the portion contacting the body, thereby shortening the time for holding the cold storage.

In the conventional ice pack, most of the cold air is supplied to the human body in order to be used in the early stage after the freezing of the freezing material. Therefore, it is necessary to avoid immediate use of the freezing material of the freezing material, There is a problem that it must endure. Meanwhile, as a solution to this problem, it is possible to propose a freezing material which can be frozen at a temperature suitable for use in a human body immediately after freezing of the freezing material. In this case, it can be pointed out that the freezing time of the ice pack is too short.

FIG. 1 is a perspective view of a cooling band using the present invention coolant, and FIG. 2 is a perspective view showing a step of manufacturing a coolant according to a cooling band using the present invention coolant.

As shown in the drawings, the cooling band using the present invention can be easily bent and includes a shaft cooling member 100 accommodated therein, and the shaft cooling member 100 is fixed to a body part of the user And a fixing member (200).

2 (a)) in which the axial coolant is accommodated, and the second tube 120 (see FIG. 2 (a)) in which the axial space is accommodated, A first tube 110 (see FIG. 2 (b)) having a large size and disposed on the outer side of the second tube 120 and containing a coolant having a melting point different from that of the second tube 120, And a heat insulating member 130 (Fig. 2 (b)) which surrounds the outer circumferential surface of the first tube 110 so as to form a substantially C-shaped cross section and forms an opening 131 in which the first tube 110 is exposed in the longitudinal direction, A third tube 140 (see FIG. 2 (d)) that surrounds the outer circumferential surface of the heat insulating member 130 to protect the heat insulating member 130, and a constriction member 100 (see FIG. (See Fig. 2 (e)) which are spaced apart from one another in a longitudinal direction of the shoaling member 100 so as to form a ring-shaped wrinkle portion 102 on the outer circumferential surface of the shoelike member 100 It is sex.

As described above, the shoaling member 100 has a plurality of wrinkles 102 whose outer diameter is reduced by the elastic bands 150 disposed in a large number of spaces, while the wrinkles 102 are arranged on the outer circumferential surface of the shoveling member 100 in the longitudinal direction. And a plurality of axial cold cells 101 are formed. The plurality of axial cold cells 101 communicate with the axial cold cells 101 adjacent to each other through the central region of the region where the corrugations 102 are formed.

In particular, the first tube 110 and the second tube 120 have a cylindrical cross-section to accommodate a relatively large amount of axial coolant compared to a tube having a conventional elliptical cross- So that it is possible to secure a relatively long accumulation holding time.

The axial coolant accommodated in the first tube 110 and the axial coolant accommodated in the second tube 120 are made of phase change materials (PCM) and are set to have different melting points. That is, in this embodiment, a structure of a composite axial coolant of a double structure will be described by way of example.

The wrinkle portion 102 formed by the elastic band 150 has a smaller radius of curvature as the spacing distance becomes narrower and a radius of curvature of the shaft member 100 as the spacing becomes wider Lt; / RTI > Therefore, the spacing of the elastic bands 150 can be adjusted by the radius of curvature required for the shaft member 100 according to the use environment.

The elasticity of the elastic band 150 is adjusted by the elasticity of the elastic band 150 so that the elasticity of the elastic band 150 can be adjusted according to the diameter of the first tube 110, Lt; / RTI >

The fixing member 200 is made of a heat insulating material such as neoprene and covers the outer side of the cooling member 100. The fixing member 200 includes an opening and closing part 202 such as a zipper so that the cooling member 100 can be easily drawn in and out, And a fixing portion 201 is formed at both ends of the fixing portion 201 so as to be fastened to each other by a velcro fastener and the opening portion 131 formed in the heat insulating member 130 of the hot- And a plurality of opening holes 203 are formed at corresponding positions.

Hereinafter, the operation of the first embodiment of the cooling band using the aforementioned axial coolant will be described.

4 is an enlarged view of a portion "A" of FIG. 4, FIG. 6 is a side sectional view of a cooling band using the present axial cold member, and FIG. 7 is a perspective view showing a state of use of a cooling band using the present invention coolant.

As shown in Figs. 4 and 5, the heat insulating member 130 is disposed outside the first tube 110 housing the axial coolant to prevent excessive heat loss of the cold energy stored in the axial coolant, And a third tube 140 is disposed on the outer side of the heat insulating member 130 to protect the heat insulating member 130.

In addition, a second tube 120 accommodating a separate axial coolant is disposed in the first tube 110. At this time, the axial coolant of the first tube 110 disposed outside the second tube 120 has a melting point lower than that of the axial coolant of the second tube 120, 2 tube 120 is set to have a higher melting point than the axial coolant of the first tube 110. [ Therefore, since the inner axial coolant (the axial coolant of the second tube) is first frozen and the outer axial coolant (the axial coolant of the first tube) is frozen, the cool energy accumulated in the axial coolant is increased more than the structure using the single axial coolant .

If the melting point of the inner axial coolant is set lower than that of the outer axial coolant and the outer axial coolant first freezes, the outer axial coolant is frozen before the inner axial coolant is frozen and the cold energy reaches the inner axial coolant by the solid freezing wall It takes a lot of time and energy to cool down the inner shaft coolant completely.

In other words, when the outside axial coolant is set to have a melting point lower than that of the inside axial coolant as in the present embodiment, the axial coolant disposed inside is surrounded by the outside axial coolant, and the cool energy can be maintained for a longer time , The cooling energy holding time of the shaft member (100) can be extended more than the shaft member (100) using the single shaft member.

A plurality of elastic bands 150 spaced apart from each other at a predetermined distance apart from the shoaling member 100 form a ring-shaped wrinkle portion 102 on the outer side of the shoveling member 100, The joint member 100 can be easily bent when the axial cold member is frozen. That is, since the diameter of the portion where the corrugated portion 102 is formed is smaller than the diameter of the adjacent axial cold cells 101, the portion where the corrugated portion 102 is formed is bent when the axial coolant 100 is bent.

Therefore, when the body member 100 is worn on the body part of the user, the body member 100 is bent by the plurality of corrugated parts 102 corresponding to the curved surface of the body part, It can be brought into close contact.

When a certain pressure is applied to the axial cold cells 101, the axial cold cells 101 accommodated in the axial cold cells 101 move to the adjacent axial cold cells 101 as well as the corrugated portions 102 formed by the elastic bands 150 The expansion member 100 can be prevented from being damaged by the external pressure.

In addition, a plurality of axial cold cells 101 separated by the corrugated part 102 are forced to have different cold energy loss rates depending on the amount of heat generated by the body parts in close contact with each other. Since the axial cold cells 101 of this embodiment are formed so that the axial cold cells 101 adjacent to each other communicate with each other through the central region of the region where the corrugations 102 are formed, Even if the heat loss in the cold cell 101 increases, the adjacent axial cold cells 101 and the axial coolant communicate with each other to perform heat exchange. Accordingly, the whole axial cold cells 101 of the constriction member 100 can cool the body part while maintaining a relatively uniform temperature.

6, the heat insulating member 130 disposed on the outer side of the first tube 110 to prevent excessive heat loss of the cold energy stored in the cold storage material has a longitudinal direction And the first tube 110 accommodating the axial coolant is exposed through the opening 131. The first tube 110 is exposed through the opening 131, Accordingly, the first tube 110 discharges the cool energy to the outside through the opening 131 of the heat insulating material, and the portion surrounded by the heat insulating material is blocked from performing heat exchange with the outside air.

The shaft member 100 is accommodated in the fixing member 200 through the opening and closing part 202 of the fixing member 200. When the opening 131 of the insulating member 130 is fitted to one side of the fixing member 200 Is inserted to correspond to the opening hole 203 formed. That is, the cold energy emitted from the sizing member 100 is supplied to the outside through the opening 131 of the heat insulating member 130 and the opening 203 of the fixing member 200, and the portion surrounded by the heat insulating material is heat- The emission of energy is blocked.

7, the user can attach the fixing parts 201 provided at both ends of the fixing member 200 to each other with the opening 203 of the fixing member 200 facing the body part, And the cooling unit 100 is wound around the body part to receive the cooling energy.

At this time, since the sizing member 100 can be easily bent through the corrugated portion 102 as described above, it is possible to freely adhere the sizing member 100 to the curved surface of the body part, Since the heat insulating member 130 is disposed at the portion facing the heat insulating member 130, the unnecessary loss of the cooling energy can be minimized.

In addition, since the fixing member 200 is made of a heat-expandable material such as neoprene and is prevented from absorbing moisture such as sweat on the surface of the fixing member 200, the fixing member 200 is excellent in wearing feeling, Part also provides the function of heat insulation, so that it is possible to prevent the cold energy from being unnecessarily lost through the outside part not in contact with the body part.

7 is a side cross-sectional view showing a modified example of the condenser according to the present invention.

In the above-described embodiment, the axial cooling member 100 is exemplified as having a double structure, that is, the first tube 110 and the second tube 120 are overlapped with each other and the axial coolant having different melting points are accommodated therein However, the present invention is not limited thereto, and it is also possible to use a single structure in which the axial coolant is accommodated in the first tube 110 as shown in FIG. 7 according to various requirements such as the manufacturing cost or the use environment.

Also in this case, since the first tube 110 has a cylindrical cross section and can accommodate a relatively large amount of axial coolant in comparison with a tube divided into a plurality of compartments by a tube or seam having a conventional elliptical cross section, It is possible to secure a long axial cooling holding time.

Next, the cooling band using the axial coolant according to the second embodiment of the present invention will be described.

8 is a perspective view showing a modification of the fixing member according to the present invention.

According to the second embodiment of the present invention, the fixing member 200 'is made of a functional fabric having quick-drying and stretching function, and the fixing portions 201 at both ends are fixed to each other by a knot, In the present embodiment is fixed by the elastic ring 204 made of the same material as rubber or silicon which binds at the same time with the fixing member 200 of the first embodiment. On the other hand, since the shaft member 100 accommodated in the fixing member 200 'has the same structure as that of the first embodiment, detailed description of the same structure will be omitted.

As shown in the figure, when the fixing portion 201 formed at both ends of the fixing member 200 'is fixed by the elastic ring 204, the position of the elastic ring 204 is moved in the direction of the arrow, ) Can be easily tightened or loosened to the body part. At this time, the elastic ring 204 is prevented from arbitrarily moving from the fixed portion 201 of the fixing member 200 'by surface friction.

In addition, since the fixing member 200 'is made of a functional fabric having quick-drying and stretching function, it quickly evaporates even if a staining liquid such as sweat of a user is deposited, thereby improving the wearing comfort and changing the user's body size and wearing area It is possible to prevent the shaft member 100 from moving arbitrarily from the wearing position as well as to be brought into close contact with the body.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
