[0020] Next, the terms used in this specification will be briefly explained, and the present invention will be specifically described.

[0021] The terms used in the present invention are selected as general terms currently widely used as much as possible while taking into consideration the functions in the present invention, but these may change according to the intentions of those skilled in the art, precedents, the emergence of new technologies, etc. Therefore, the terms used in the present invention are defined based on the meanings that the terms have and the overall content of the present invention, rather than simply the names of the terms.

[0022] Throughout the specification, when a part is said to "comprise" a certain element, this does not mean to exclude other elements, but means that it can further include other elements, unless specifically stated to the contrary.

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a semiconductor device according to an embodiment of the present invention;

[0024] The specific matters including the problems to be solved in the present invention, the means for solving the problems, and the effects of the invention are included in the embodiments and drawings described below. The advantages and features of the present invention, as well as the methods for achieving them, will be apparent from the embodiments described in detail below together with the accompanying drawings.

[0025] The invention will now be described in more detail with reference to the accompanying drawings.

[0026] Referring to Figures 1 and 2, a cooling pad for a hat according to a first preferred embodiment of the present invention includes a disk-shaped base part 100 formed by fusing a skin 101 and a subskin 102, and a foam part 200 protruding from the base part 100, and the foam part 200 is formed in multiple pieces and filled with different phase change materials.

[0027] The base part 100 is provided in a disk shape, and has a plurality of cutout parts 100-1 arranged radially from the center, which are formed into a corresponding fan shape when worn on the user's head. The base part 100 is manufactured into a rectangular flat plate shape as a whole by an air pressure high frequency fusion machine, and is integrally formed with the foam part 200 by a mold during fusion. That is, the base part 100 has a fusion line 130 formed in the remaining area excluding the foam part 200 when the epithelium 101 and the hypodermis 102 are fused, and the shape of the foam part 200 is changed along the fusion line 130.

[0028] As an example, the plurality of foam parts 200 may be formed in a semicircular or arc shape by chamfering the edges. That is, the plurality of foam parts 200 includes a plurality of semicircular foam parts 200-1 or arc foam parts 200-2, and are provided in a shape surrounding the user's head when provided inside the hat. The base part 100 plays a role of supporting the foam part 200 by being in close contact with the inner leather of the hat so that the foam part 200 does not move when in contact with the inner leather of the hat. At this time, the plurality of semicircular foam parts 200-1 or arc foam parts 200-2 are uniformly arranged all over the disk-shaped base part 100.

[0029] More specifically, the foam part 200 includes a plurality of first foams 201 formed in the center of the base part 100, a plurality of second foams 202 formed to surround the first foams 201, a plurality of third foams 203 radially arranged on the outside of the second foam 202 with respect to the center of the first foam 101, and a plurality of fourth foams 204 radially extending from the plurality of third foams 203. As an example, the plurality of first foams 201 may be provided in a semicircular shape with the fusion line 130 formed in the center, and the plurality of second foams 202, the third foam 203, and the fourth foam 204 may be formed in an arc shape.

[0030] In this case, the first foams 201, the second foams 202, the third foams 203, and the fourth foams 204 are each filled with a phase change material (PCM), and the phase change material filled in the first foams 201 and the second foams 202 changes phase at a lower temperature than the phase change material filled in the third foams 203 or the fourth foams 204.

[0031] More specifically, referring to Table 1 below, the first and second foams 201 and 202 are filled with a phase change material that undergoes a phase change at 18° C., and the third and fourth foams 203 and 204 are filled with a phase change material that undergoes a phase change at 22° C. or a phase change material that undergoes a phase change at 38° C. That is, the third and fourth foams 203 and 204 may be filled with a phase change material that undergoes a phase change at 22° C. The third and fourth foams 203 and 204 may be filled with a phase change material that undergoes a phase change at 22° C. The third and fourth foams 203 and 204 may be filled with a phase change material that undergoes a phase change at 22° C. The third and fourth foams 203 and 204 may be filled with a phase change material that undergoes a phase change at 28° C. The third and fourth foams 203 and 204 may be filled with a phase change material that undergoes a phase change at 28° C. In this way, the first and second foams 201 and 202 are filled with a phase change material that undergoes a phase change at a relatively low temperature, which is advantageous in improving the cooling performance for the top of the head where the most heat is distributed. Also, the third and fourth foams 203 and 204 are advantageous in increasing the time for which the first and second foams 201 and 202 can maintain their cooling performance.

[0032] [Table 1]

[0033] On the other hand, the foam part 200 is formed in a plurality of pieces and is formed to have different thicknesses. More specifically, the plurality of third foams 203 are formed to have a thickness smaller than the plurality of first foams 201, second foams 202, and fourth foams 204. That is, the plurality of first foams 201 and second foams 202 are formed thicker than the plurality of third foams 203, which is advantageous in that the amount of phase change material for cooling the top of the head can be maximized and the cooling performance can be maintained for a longer period of time. Also, the plurality of fourth foams 204 are formed to have a thickness larger than the plurality of third foams 203 and contact the outer circumferential surface of the bent head. In other words, the plurality of fourth foams 204 are formed to have a relatively maximum thickness, which is advantageous in that the gaps around the head can be covered by the difference in thickness and the gaps on the sides of the hat can be filled evenly, thereby improving the stable wearing comfort of the hat.

[0034] Hereinafter, a cooling band for a hat according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings. This embodiment is different from the first embodiment in that the fourth foam part 204 is formed to have a greater thickness than the first foam 201 and the second foam 202. The description of the first embodiment is used for the configuration overlapping with this embodiment.

[0035] 3 and 4, the plurality of fourth foams 204 are formed to have a thickness greater than the plurality of first foams 201 and the plurality of second foams 202. Furthermore, the plurality of fourth foams 204 are formed to have a thickness greater than the plurality of third foams 203 so as to contact the outer circumferential surface of the bent head. That is, the plurality of fourth foams 204 are formed to have a relatively maximum thickness, and have an advantage of being able to cover the gaps around the head with the difference in thickness and to evenly fill the gaps on the sides of the hat, thereby improving the stable wearing comfort of the hat. In addition, a relatively large amount of phase change material is filled, and therefore, there is an advantage of being able to further increase the maintenance time of the cooling performance of the plurality of first foams 201 and the second foams 202.

[0036] Meanwhile, the first forms 201 may be formed to have a thickness smaller than that of the second forms 202 so that a top button formed at the upper end of the hat can be accommodated therein, which has the advantage of improving the comfort of wearing the hat.

[0037] On the other hand, the plurality of first foams 201 may be formed to have a thickness greater than or equal to the plurality of second foams 201 and greater than or equal to the plurality of third foams 203. Also, the plurality of fourth foams 204 may be formed to have a thickness greater than or equal to the plurality of third foams 203 and greater than or equal to the plurality of first foams 201 and second foams 202. In this way, the thicknesses of the plurality of first foams 201, second foams 202, third foams 203, and fourth foams 204 may be different from each other, and the cooling performance of the cooling pad for hat of the present invention may be modified and applied as necessary.

[0038] Hereinafter, a cooling pad for a hat according to a third embodiment of the present invention will be described in detail with reference to the accompanying drawings. This embodiment is different from the first embodiment in that the base part 100 includes a lower base part 110 and an upper base part 120 laminated and fused to the lower base part 110, and the foam part 200 includes a lower foam part 210 formed to protrude downward from the lower base part 110 and an upper foam part 220 formed to protrude upward from the upper base part 120. The description of the first embodiment is used for the configuration overlapping with this embodiment.

[0039] 5 and 6, the base portion 100 includes a lower base portion 110 and an upper base portion 120 that is laminated and fused to the lower base portion 110, and the foam portion 200 includes a lower foam portion 210 that protrudes downward from the lower base portion 110, and an upper foam portion 220 that protrudes upward from the upper base portion 120.

[0040] More specifically, two of each of the skins 101 and underskins 102 are provided, and the skins 101 and underskins 102 provided on the upper side are primarily fused by a mold to form the upper base part 120 and the plurality of upper foam parts 220, and the skins 101 and underskins 102 provided on the lower side are secondarily fused by a mold to form the lower base part 110 and the plurality of lower foam parts 210. Here, the plurality of lower foam parts 210 and the upper foam part 220 each include the plurality of first foam parts 201, second foam parts 202, third foam parts 203, and fourth foam parts 204.

[0041] Also, the upper foam parts 220 and the lower foam parts 210 are filled with different phase change materials. The upper base part 120 and the lower base part 110 are tertiary fused and bonded to each other by a mold. That is, the upper base part 120 and the lower base part 110 are fused and provided in a flat plate shape, and the lower foam parts 210 and the upper foam parts 220 are provided symmetrically to each other. As an example, the primary fusion and secondary fusion are performed by using an air pressure high frequency fusion machine set to 5KW, and the tertiary fusion is performed by using an air pressure high frequency fusion machine set to 13KW to fuse four raw materials to prepare the base part 100.

[0042] Here, the plurality of lower foam parts 210 and the upper foam parts 220 are filled with phase change materials that undergo a phase change at different temperatures. Referring to Table 1, the plurality of lower foam parts 210 may be filled with a phase change material that undergoes a phase change at a lower temperature than the phase change material that is filled in the plurality of upper foam parts 220. For example, the plurality of lower foam parts 210 may be filled with a phase change material (PCM) that undergoes a phase change at 18°C ​​or less, and the plurality of upper foam parts 220 may be filled with a phase change material that undergoes a phase change at 28°C or more. Thus, when the user is exposed to a desired temperature of the plurality of lower foam parts 210 or the upper foam parts 220, the surface on which the foam part 200 is formed can be placed under the hat. In other words, the configuration is such that the user can selectively adjust or change the temperature as needed.

[0043] In addition, the lower foam sections 210, which undergo a phase change at 18°C ​​or less, are colder than the upper foam sections 220, which undergo a phase change at 28°C or more, but have a faster cooling rate, so the upper foam sections 220 play a role in assisting the cooling temperature and time of the lower foam sections 210.

[0044] For example, at a room temperature of 27° C., the plurality of upper foam parts 220 increases the time during which the plurality of lower foam parts 210 maintain their coolness. That is, the combination of the plurality of lower foam parts 210, which undergo a phase change at 18° C. or less, and the plurality of upper foam parts 220, which undergo a phase change at 28° C. or more, allows the cap to be cooled for a longer period of time. In other words, if only a single phase change material, which undergoes a phase change at 18° C. or less, is filled, the phase change material melts at a room temperature of 19° C., but in the present invention, the phase change material of the plurality of upper foam parts 220, which undergo a phase change at 28° C. or more, absorbs the external temperature to reduce the melting speed of the phase change material of the plurality of lower foam parts 210, which undergo a phase change at 18° C. or less, thereby providing an advantage that the cap can be maintained cool for a longer period of time. Furthermore, referring to Figures 7 to 10, it can be seen that sample 3 (200 g), which is filled with a larger amount of phase change material, maintains a lower temperature for a longer period of time than sample 1 (100 g), which is filled with a relatively smaller amount of phase change material.

[0045] As a result, the cooling pad for a hat of the present invention can be inserted inside the hat to cool the user's head, and has the advantage of improving cooling efficiency.

[0046] As described above, the technical configuration of the present invention can be embodied in other specific forms by a person skilled in the art to which the present invention pertains without changing the technical idea or gist of the present invention.

[0047] Therefore, the above-described embodiments are illustrative in all respects and are not limiting, and the scope of the present invention is defined by the claims described below rather than the above detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention. In addition, the above-described embodiments may be applied in combination. [Explanation of symbols]
