Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic flow chart illustrating a process of a basic type cooling tube ring manufacturing method according to an embodiment of the present invention. FIG.

Referring to Fig. 1, there is shown, in accordance with an aspect of the present invention, the process of the simplest form of cooling tube ring manufacturing method (10). This includes a sheet preparation step 11, a thermal bonding step 13, and a phase change liquid 15 (Phase Change Materials (PCM) phase change materials at a predetermined temperature).

The sheet preparing step (11) is a step of lapping two sheets of elastic and thermoplastic polyurethane sheets. After two sheets are laminated, they can be pressed together by pressing them with a roller, for example, so that the air layer is minimized between them. Since the polyurethane sheet is a thermoplastic resin sheet, there is an advantage that a heat bonding operation can be easily performed by using an apparatus such as a high-frequency thermal fusing apparatus. Also, since the polyurethane sheet maintains elasticity even at a low temperature of minus zero, it is advantageous in that even when the phase change material is freezing, even when pulled out to widen the opening portion of the cooling tube ring, the tearing phenomenon does not occur. Further, the polyurethane sheet itself may contain color, or a printed pattern may be included on the polyurethane sheet.

When the laminated two-ply sheets are prepared as described above, the thermal bonding step 13 may be performed in which the laminated two-ply sheets are thermally bonded using, for example, a high-frequency fuser equipped with a mold corresponding to a predetermined annular thermal bonding line. As a result, a ring-shaped arc tube (or arc band) in which only the injection port for filling the phase change material between the two layers of sheets is opened and the space of the long and narrow tubular part is partially opened can be manufactured. The space in the arc tube thus produced constitutes a receiving portion for filling the phase change material.

When the receiving portion of the arc tube is formed by the thermal bonding step 13, the portion of the non-receiving sheet other than the receiving portion is removed, and the phase change material is filled and sealed through the injection port to complete the cooling tube ring having the desired annular shape (15).

The term "phase change material" as used herein is well known as PCM (phase change material). It refers to a substance other than water which causes a phase change at 0 ° C and can absorb or release a lot of heat as the state of the substance changes at a user-desired temperature, such as 5 ° C, 10 ° C, 15 ° C or 20 ° C And the like. This material mainly uses latent heat and is sometimes called a heat storage material. In general, PCMs can be classified into organic substances such as hydrocarbons such as tetradecane, octadecane, and nonadventane, inorganic substances such as calcium chloride in the form of hydrate, and vegetable substances obtainable from nature. According to NASA research, 100 ~ 200 PCMs are actually available. Originally PCM was developed to protect spacecraft and astronaut from external temperature changes, but recently it has been widely applied to general consumers such as air conditioning system using room temperature (5 ℃ storage) PCM.

According to the present invention, 'phase-change material' is a substance that causes phase change at a specific temperature selected from 5 to 20 ° C, and can be used without limitation as long as it is not volatile and has no alcohol component. If volatile, the volatile gas component permeates through the polyurethane sheet and diverges. Therefore, the use period may be limited, and if the alcohol component is contained, the alcohol component melts the polyurethane sheet, .

As described above, according to the manufacturing method of the cooling tube ring according to the present invention, the annular tube partially opened is made of a thermoplastic elastic resin sheet (for example, polyurethane) by using a high frequency welding machine, And then sealed with a high-frequency welder to complete a cooling tube ring product.

Such a finished cooling tube ring, in accordance with a preferred embodiment of the present invention, is filled with a phase change material that is liquid at room temperature in an annular tube made of a flexible and elastic polyurethane sheet, A tension sufficient to mechanically maintain the ring shape is provided. The flexible polyurethane sheet is also soft and elastic so that it can have a pleasant feel, for example, when touched by hand or contacted with the neck.

2 is an exemplary side view for explaining a state in which a polyurethane sheet is thermally adhered in the process of manufacturing a cooling tube ring according to an embodiment of the present invention.

Referring to FIG. 2, FIG. 2 (a) shows a state in which two polyurethane sheets 21 and 22 are laminated. 2 (b) shows a state in which the two sheets 21 and 22 shown in Fig. 2 (a) are thermally adhered in a predetermined pattern using, for example, a high-frequency fusion splicer, The housing portion 24 is formed. As shown in FIGS. 3 to 9, the receptacle 24 is an annular tube partially opened, and is a portion where the phase change material is filled through an injection port (not shown). On the other hand, FIG. 2 (c) shows a state in which the accommodating portion 24 is deformed in a two-dimensional planar shape by the phase change material PCM being charged in the process of injecting the phase change material PCM into the accommodating portion 24 Dimensional tube shape. When the filling is completed, the cross section of the accommodating portion 24 is in the form of a generally circular plump shape, as schematically indicated by a dotted circle. Accordingly, the shape of the accommodating portion 24 deformed into a three-dimensional tube shape is smaller than that in the two-dimensional flat state (state (b) of FIG. 2) 24 is increased, and the width in the horizontal direction is contracted. Accordingly, although the polyurethane sheet itself is flexible, it can not maintain a mechanical tension sufficient to maintain the overall shape. However, by filling the phase change material with the internal space of the accommodating portion, the tension necessary for maintaining the overall shape mechanically Can be provided sufficiently.

3 is a schematic top view showing morphological changes before and after injecting a phase change material into a cooling tube ring according to an embodiment of the present invention.

3 (a) schematically shows an arc band 30 before injecting a phase change material liquid, and Fig. 3 (b) Lt; RTI ID = 0.0 > 30 ' after < / RTI > The arcuate portion of the arc band 30 is open at both open ends of the open portion from the center M by an angle of a1. When the phase change material is injected into the arc portion, the elastic polyurethane sheet forming the arc portion is expanded by the injected phase change material. At this time, due to the force exerted by the phase change material on the polyurethane sheet, the length of the polyurethane sheet is increased, and as a result, the narrow open end is extended. Therefore, the opening width a2 between the open ends of the cooling tube ring 30 'becomes narrower than the opening width a1 of the arc bands 30 before injecting the phase change material liquid.

In an embodiment, the opening angle a1 of the opening of the arc band 30 may range from 0 to 180 degrees at the center M of the arc band. When the angle a1 is 0 degrees, the corresponding opening angle a2 after the injection of the phase change material is about -10 degrees, so that the open ends are partially overlapped. However, It is enough to hold both open ends and pull it on both sides to wear on the neck or to remove it. When the angle a1 is 180 degrees, the corresponding opening angle a2 after the injection of the phase change material is about 170 degrees, so that it is possible to maintain the shape of the anti-circular gauge to such an extent that it can not easily fall off when worn on the neck. In the case of the preferred embodiment, the width of the opening of the arc band 30, i.e. the distance between both open ends, is about 3-5 cm. In this case, the corresponding opening angle a2 after the injection of the phase change material is about 0 ° to 5 °, which makes it convenient and convenient to wear and detach.

FIG. 4 is a perspective view illustrating a cooling tube ring according to an embodiment of the present invention, and FIG. 5 shows a state where the cooling tube ring illustrated in FIG. 4 is worn on the neck.

Referring to Fig. 4, a hoofed cooling tube ring 40 according to the present invention is illustrated. The hoof-like annular shape is uniform in the thickness of the arcuate portion, and both open ends are substantially in contact with each other at the front of the neck. In this example, it can be seen that the burrs of the inner line and the outer line generated by the thermal bonding line remain when the arc portion is manufactured. In this case, depending on the person, the burr of the inner line touches the neck, .

When the cooling tube ring 40 of this example is worn on the neck as illustrated in Fig. 5, the vertebral artery passes through the back of the person's neck, and the carotid artery passes from the front side of the neck to both sides. The portion corresponding to the position of the blood vessels melts faster than the other portion. Therefore, this embodiment can be seen to melt faster at the back and side, and later to melt the phase change material of the front open end.

FIG. 6 is a perspective view illustrating a banana-type cooling tube ring to maximize cooling efficiency according to another embodiment of the present invention, and FIG. 7 is a perspective view illustrating a state where the banana-type cooling tube ring of FIG. 6 is worn on the neck.

Referring to Fig. 6, a banana-type cooling tube ring 60 according to the present invention is illustrated. The shape of the banana-shaped annulus is thicker at the back and thinner at the front, so that it has a banana-like shape. In this example, it can be seen that there is no inner line burr and only the outer line burr remains as a thermal junction line that occurs when the arc portion is manufactured. A manufacturing method of eliminating the burr of the inner line in contact with the human's neck will be described in more detail by the embodiments described below with reference to Figs. 10 to 24.

When the cooling tube ring 60 of this example is worn on the neck as illustrated in Figure 7, the portion corresponding to the back of the person's neck is thicker and thinner in the frontal direction, The phenomenon of depriving the heat is the same, but the phase change material of the entire rear part and the open end part of the front can be melted as a whole in approximately the same time.

8 is a schematic plan view illustrating a cooling tube ring for minimizing the contact area according to another embodiment of the present invention.

Referring to Fig. 8, there is shown a modified cooling tube ring 80 that minimizes the area of contact with a person's neck. In the illustrated embodiment, the inner surface of the arc portion of the cooling tube ring 80, that is, the surface that contacts the neck when worn, has a concave-convex structure. That is, convex portions. Since the convex portion forms a contact surface that makes direct contact with the neck, the contact surface area in this example is smaller than the entire inner surface area. In this case, the position of the contact surface (i.e., the convex portion) is arranged to correspond to an average position of the blood vessel passing through the human neck, that is, a position such as the back of the neck through which the vertebral artery passes and both side surfaces of the neck through which the carotid artery passes.

According to this embodiment, since the contact area with the neck is minimized, a product suitable for a sensitive person who feels an uncomfortable feeling when foreign substances come into contact with the skin can be provided.

Further, in order to improve the tactile feel of the surface of the cooling tube ring which is in contact with the neck according to the present invention, for example, by a micro-irregular structure generated by a matte treatment by matting the polyurethane sheet constituting the contact surface of the cooling tube ring The feel can be improved.

FIG. 9 is a schematic plan view illustrating a gold-plated cooling tube ring having a structure for ease of wear and tear down according to another embodiment of the present invention.

Referring to FIG. 9, the open end of the safeguard attachment cooling tube ring 90 has an outwardly rounded shape, thereby preventing a phenomenon in which both ends are interfered with the neck, rather than being inserted or removed from the neck, Can be provided. Such a cooling tube ring 90 is a shape suitable for a user having a sensitive nature who does not like the phenomenon that the neck and the open end interfere with each other because the open end is rounded like a Sono Ohgyo Kagi.

While various forms of cooling tube rings have been illustrated above, the present invention may also be made such that the receiving portion is not one, but has two receiving portions. For example, a partially open annular tube, that is, a cross section of the receiving space in which the phase change material is received, can be made up of two separate receptacles for receiving different materials. The two receptacles may be filled with air and a phase change material, respectively, or charged with two different phase change materials controlled to cause a phase change at different temperatures. These embodiments are further described below with reference to Figures 14 to 24. [

10 is a schematic flow diagram illustrating the process of a method of manufacturing a cooled tube ring with a burr removed of a contact surface according to another embodiment of the present invention.

Referring to FIG. 10, there is shown a process of a method 100 of manufacturing a cooling tube ring of the type in which the burrs are removed from the inner surface in contact with the neck, according to another aspect of the present invention. This includes a sheet preparation stage 101, an internal column junction stage 103, an inverting stage 105, an external column junction stage 107, and a phase change liquid charge stage 109.

The sheet preparing step 101 is a step of lapping two sheets of elastic and thermoplastic polyurethane sheets similar to the sheet preparing step 11 of Fig. After two sheets are laminated, they can be pressed together by pressing them with a roller, for example, so that the air layer is minimized between them.

When the stacked two-ply sheets (the first sheet and the second sheet) are prepared, a thermal bonding step of performing thermal bonding using a high-frequency fusion machine equipped with a mold corresponding to a predetermined annular thermal bonding line is performed do. According to this embodiment, unlike the thermal bonding step 13 which can be done with one mold illustrated in FIG. 1, the inner line thermal bonding step 105, the flip step 107 and the outer line thermal bonding step 107 ).

The inner line thermal bonding step 105 is a step of thermally bonding an inner line corresponding thermal bonding line located on the inner surface of the arc band to be in contact with the neck during wear, using a high frequency fusing device. In this case, the inner line is actually partially open-looped, but the inner line corresponding thermal bonding line that is thermally bonded in the inner line thermal bonding step 105 has a shape corresponding to the closed circle and corresponds to the closed circle by thermal bonding Is removed as an unnecessary portion, and consequently, a hole surrounded by the inner line corresponding thermal bonding line is formed.

Flipping step 107 inverts the first sheet or second sheet about the inner line corresponding thermal bonding line so that the bur formed by the inner line corresponding thermal bonding line is located between the first sheet and the second sheet.

Then, in the external line thermal bonding step 107, the external linear thermal bonding line of the arc tube is heated with a high frequency fusing device in a state where a bur formed by the inner line corresponding thermal bonding line between the first sheet and the second sheet is located .

As a result, a ring-shaped arc tube (or arc band) in which only the injection port for filling the phase change material is opened between the first sheet and the second sheet and the space of the long and narrow tube shape is partially opened can be manufactured, Is located inside the arc tube, that is, in the receiving portion for filling the phase change material.

For example, when the first accommodating portion is filled with air and the second accommodating portion is filled with the 5-phase change material, the total weight of the first accommodating portion and the second accommodating portion may be reduced Can be provided. On the other hand, the first accommodating portion and the second accommodating portion may be filled with different phase change materials that change phase at different temperatures. In this case, since the phase changes at different temperatures, it is possible to manufacture a product with a higher cooling efficiency depending on the case.
