Description

[Technical field]

[0001] This invention relates to a cooling device that cools objects such as fabric products and electronic devices by using the heat of vaporization of water retained in a water-retaining layer (moisture-retaining layer), and also to clothing equipped with such a cooling device. [Background technology]

[0002] 2. Description of the Related Art When living or working in high temperatures on hot summer days, clothing called air-conditioned clothing is available on the market. The clothing has a fan attached to it to circulate air inside the clothing, thereby cooling the air inside the clothing.

[0003] Furthermore, in devices such as personal computers that use integrated circuits and require active heat dissipation, various means have been developed for simply and effectively cooling such devices.

[0004] Patent Document 1 describes an invention in which a water retention sheet 100 equipped with a fan 110 is attached and a jacket (not shown) is worn from the outside, as shown in FIG. 15(a). In the invention described in Patent Document 1, an air passage is formed between the water retention sheet and the jacket by the wind of the fan, and the body of the wearer is cooled. The water retention sheet 100 has variations shown in FIG. 11(b), (c), and (d) in order to improve the discomfort caused by the contact of the water retention sheet containing moisture with the wearer. In (b), a waterproof part 103 (e.g., a PVC sheet, etc.) that does not allow water to pass through is arranged on the skin side of the water retention part 105, and the upper ends of each are sewn. In (c), a waterproof part 103 (e.g., a PVC sheet, etc.) that does not allow water to pass through is layered on the back side of the water retention part 105 to form a single sheet. In (d), an isolation layer 108 (a coarse mesh sheet, etc.) is arranged on the skin side of the water retention part 105, and the upper ends of each are sewn. In the invention described in Patent Document 1, a water-retaining sheet is immersed in water and then lightly squeezed or sprayed with water to absorb the water.

[0005] In the invention described in Patent Document 1, the temperature inside the clothing is lowered by flowing air cooled by the heat of vaporization generated when the water stored in the water retention sheet evaporates through an air duct. Therefore, the temperature inside the clothing cannot be lowered after all the water stored in the water retention sheet has evaporated, and Patent Document 1 does not mention the idea of ​​continuing to supply water to the water retention sheet while the wearer is using it. Furthermore, in the invention described in Patent Document 1, because cooled air is flowed through an air duct, most of the air is released outside the clothing. Patent Document 1 does not mention the idea of ​​cooling the object to be cooled by circulating air around the moisture retention layer. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Utility model registration No. 3213394 Summary of the Invention [Problem to be solved by the invention]

[0009] (1) The problem is solved by a cooling device comprising a moisture retention layer that retains water, an isolation layer that isolates the water retained in the moisture retention layer from coming into direct contact with an object to be cooled, and a blower fan that generates an air flow toward the moisture retention layer, wherein the moisture retention layer and the isolation layer are both made of materials with excellent breathability, overlap with each other, and extend along and in close proximity to the object to be cooled, and the cooling device cools the object to be cooled by circulating cool air around the moisture retention layer around the moisture retention layer.

(4) The problem is solved by the cooling device described in (3), characterized in that the moisture-retaining layer is made of a mesh cloth made of 100% polyester and has 36 meshes per cm2. (5) The problem is solved by the cooling device described in (3), characterized in that the isolation layer is made of a mesh cloth having 5 meshes per cm2 and a thickness of 0.4 mm to 10.0 mm. (6) The problem is solved by the cooling device described in (1), characterized in that the water retained by the moisture retention layer seeps out from small holes drilled in pipes arranged along the surface of the moisture retention layer and diffuses into the moisture retention layer. (7) The problem is solved by the cooling device described in (1), characterized in that the water retained by the moisture retaining layer is water sprayed from the discharge hole of a spray mechanism. (8) The problem is solved by the cooling device described in (1), characterized in that the moisture retention layer and the isolation layer are both made of materials with excellent breathability, so that the air generated by the blower fan passes smoothly through the moisture retention layer and the isolation layer, and cool air circulates around the moisture retention layer. (9) The problem is solved by the cooling device described in (1), which is characterized in that a layer with high thermal conductivity is disposed between the cooling object. (10) A cooling device according to (1), characterized in that two objects to be cooled are arranged on either side of the cooling device, and the two objects to be cooled are cooled by one cooling device. (11) The problem is solved by clothing equipped with the cooling device described in (6), in which a tube arranged along the surface of the moisture retention layer is arranged at a position on the surface of the moisture retention layer that is located upward in the direction of gravity when the wearer is wearing the clothing. (12) A garment that cools a wearer by cooling the air inside the garment, the garment comprising a moisture retention layer made of cloth and retaining water, an isolation layer that isolates the water retained in the moisture retention layer from coming into direct contact with the garment, and a blower fan for generating an air flow toward the moisture retention layer, the moisture retention layer and the isolation layer both being made of highly breathable materials, overlapping and extending along and adjacent to the garment, and the problem is solved by a garment that cools the air inside the garment by circulating cool air around the moisture retention layer around the moisture retention layer. (13) A cooling device that cools an electronic device by cooling the air around the electronic device, comprising: a moisture retention layer made of cloth and retaining water; an isolation layer that isolates the electronic device so that the water retained in the moisture retention layer does not come into direct contact with the electronic device; and a blower fan for generating an air flow toward the moisture retention layer, wherein the moisture retention layer and the isolation layer are both made of a material with excellent breathability, overlap with each other, extend along and in close proximity to the electronic device, and the air around the electronic device is cooled by circulating cool air around the moisture retention layer around the moisture retention layer, and the problem is solved by a cooling device in which a layer with waterproof properties and high thermal conductivity properties is disposed between the electronic device and the moisture retention layer.

[0010] In the solution (1), the moisture retention layer and the isolation layer are made of a material having excellent breathability, and the layers overlap and extend along the cooling target, so that air around the moisture retention layer circulates well. The moisture retention layer may be made of cloth. The moisture retention layer may be made of a sponge that extends thinly like cloth. Air flowing toward each layer flows smoothly through each layer, and the evaporation of the moisture retention layer can be promoted. In the solution (1), the cool air around the moisture retention layer circulates around the moisture retention layer, so that the air is cooled every time the circulating air passes through the moisture retention layer. As a result, the cooling target can be effectively cooled. In the solution (1), a blower fan for generating an air flow toward the moisture retention layer is provided, so that the air flow is generated and fresh air from the outside is supplied to maintain the evaporation of the moisture retention layer. In addition to cloth products such as clothing, pillows, and cushions, electronic devices such as personal computers, servers, and mobile phones can also be used as cooling targets. By evaporating liquefied carbon dioxide, it is possible to cool the object to near zero degrees.

[0011] In the solution (2), the evaporation assistance layer promotes the evaporation of the water retained in the moisture retaining layer, and cooling is performed more effectively.

[0012] In the solution (3), since both the moisture retaining layer and the isolating layer are made of mesh cloth, excellent breathability of these layers can be easily obtained.

[0013] In solution (4), the moisture retaining layer uses a mesh with relatively small openings to retain moisture.

[0014] In the solution (5), the isolation layer uses a relatively thick mesh to isolate the moisture retaining layer from the object to be cooled.

[0015] In the sixth aspect, water can be continuously supplied through the tube by using water that seeps through small holes drilled in the tube arranged along the surface of the moisture retaining layer and diffuses into the moisture retaining layer. Also, the amount of water that diffuses can be adjusted by adjusting the size and number of the small holes.

[0016] In the seventh aspect of the present invention, the water can be continuously provided through the spray mechanism by using the water sprayed from the outlet hole of the spray mechanism. Also, by using the sprayed water, the water can be evaporated during the spraying, which helps to cool the surrounding air.

[0017] In the eighth aspect of the present invention, the cool air circulates around the moisture retention layer, and the object to be cooled that has been cooled by the cool air circulates, further cooling the air around the moisture retention layer. As a result, the object to be cooled can be cooled efficiently.

[0018] In the solution (9), by disposing a layer with high thermal conductivity, the cool air around the moisture retention layer can be transmitted to a wide area of ​​the object to be cooled in a short period of time.

[0019] In the solution (10), two or more objects can be cooled by effectively utilizing the cool air around the moisture retaining layer. For example, when the cooling device is attached to the clothing, the body of the person wearing the clothing inside the clothing and the outer surface of the clothing can be cooled. As a result, when the person wearing the clothing wants to cool his / her hands that are exposed outside the clothing on a hot summer day, he / she can cool his / her hands by touching the outer side of the clothing.

[0020] In the solution (11), water permeates the fabric from above to below due to gravity. Then, the water that flows downward rises in the fabric due to capillary action. This makes it possible to effectively obtain moisture retention in the moisture retention layer.

[0021] In the solution (12), the body of the person wearing the clothing can be effectively cooled.

[0022] In the solution (13), devices that use integrated circuits and require active heat dissipation, such as personal computers, can be cooled simply and inexpensively. The power required for cooling is only that used for the blower fan. [Brief description of the drawings]

[Figure 15] A conventional example is shown. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0024] The mechanism by which the cooling layer 1 according to the first embodiment lowers the temperature around the cooling layer 1 will be described with reference to FIGS.

[0025] The cooling layer 1 includes a moisture retention layer 5, a vaporization assistance layer 8, and an isolation layer 7. The moisture retention layer 5, the vaporization assistance layer 8, and the isolation layer 7 are all made of mesh cloth to ensure breathability.

[0026] The moisture retention layer retains water. The moisture retention layer 5 is provided with a tube 6 through which water passing through it seeps outward and supplies water to the moisture retention layer. The moisture retention layers (5a, 5b) are two layers sandwiching the tube 6. The moisture retention layers (5a, 5b) wrap the tube 6 from above and receive the liquid seeping out from the tube 6. The water rapidly diffuses throughout the moisture retention layer and is retained in the moisture retention layer. The moisture retention layers (5a, 5b) split into two parts from the tube 6 and hang down due to gravity in order to retain as much liquid seeping out from the tube 6 as possible. The moisture retention layer 5 hangs down due to gravity, and the water stored in the moisture retention layer 5 accumulates at the end of the moisture retention layer 5 due to gravity. The water accumulated at the end rises up the moisture retention layer 5 due to capillary action and re-wets the moisture retention layer.

[0027] The moisture retaining layers (5a, 5b) are made of chemical fibers with high water absorption and quick drying properties. For example, they are made of 100% polyester mesh cloth. For the moisture retaining layers, mesh cloth with a weave of 45 / inch, a course of 60 / inch, a thread count of 50 denier x 50 denier, and a basis weight of 103 g / m2 is used so that the surface area of ​​the fabric is large and moisture can be retained. In addition, to improve breathability, mesh with about 36 holes per cm2 is used.

[0028] The evaporation assistance layer 8 only needs to be disposed adjacent to the moisture retention layer 5, and may be exposed on the surface of the cooling layer on the opposite side of the cooling target 10 as shown in Fig. 1(a). Alternatively, the evaporation assistance layer 8 may be disposed between the moisture retention layer 5 and the isolation layer 7 as shown in Fig. 1(b).

[0029] The evaporation assist layer assists the evaporation of water in the moisture retention layer. The evaporation assist layer is made of the same highly absorbent and quick-drying chemical fiber as the moisture retention layer. For example, it is made of 100% polyester mesh cloth. To improve breathability, the evaporation assist layer uses a mesh with a relatively larger opening than the moisture retention layer. For example, a mesh cloth with a thread count of 32 wells / inch, a course of 58 / inch, a thread count of 50 denier x 50 denier, and a basis weight of 64 g / m2 is used. To further improve breathability, for example, a mesh with about 36 holes per cm2 is used.

[0030] The isolating layer 7 separates the moisture retention layer 5 from the object to be cooled 10 so that the object to be cooled does not come into contact with the moisture retention layer 5. For this reason, the isolating layer 7 is disposed on the side of the cooling layer 1 that is the object to be cooled. The isolating layer is made of polypropylene, polyester, or the like. When the cooling layer 1 is used for clothing, by orienting the isolating layer 7 toward the skin side of the human body, the wearer can be prevented from feeling sticky and uncomfortable due to water touching the skin.

[0031] The mesh cloth of the isolation layer 7 is thick enough to prevent moisture in the moisture retention layer from coming into contact with the cooling target 10. For example, a thickness of 0.4 mm to 10.0 mm and about 5 mesh holes per cm2 is used.

[0032] 2, the cooling layer 1 according to Example 1 has excellent air permeability, so that air flowing toward the cooling layer passes through the cooling layer 1, hits the object 10 to be cooled, changes direction, and flows toward the cooling layer 1. As a result, cooling by the cooling layer 1 is repeated.

[0033] The cooling layer 1 used in the clothing according to the embodiment 1 will be further described with reference to Figures 3 and 4. In Figure 3, the evaporation assistance layer 8 of the cooling layer 1 is omitted.

[0034] As shown in Fig. 3, the tube 6 is sandwiched between two moisture retention layers (5a, 5b) and the top and bottom of the tube 6 are sewn together to integrate the tube 6 with the two moisture retention layers (5a, 5b). Furthermore, an isolation layer 7 is placed in contact with the moisture retention layer 5a, and the moisture retention layers (5a, 5b) are sewn to the isolation layer 7. As shown in Fig. 3, an evaporation assistance layer 8 is placed on the side of the two moisture retention layers (5a, 5b) opposite to the side where the isolation layer 7 is present.

[0035] The tube 6 has many small holes on the side, and is made of silicone rubber with an inner diameter of 1 mm to 2 mm, an outer diameter of 2 mm to 4 mm, and a hardness of 45 to 55 degrees, for example. The diameter of the small holes is 0.1 mm to 0.3 mm, and when made of silicone rubber, the elasticity of the silicone rubber can be used to prevent the small holes from opening too much by adjusting the pressure of the water passing through the tube, and this makes it possible to make the amount of water seeping out from the small holes just right. The material of the tube is not limited to silicone rubber, and any tube that allows water to seep out from the small holes in the wall just right can be used. For example, vinyl, polyurethane, polyethylene, nylon, PTFE, PVDF, ETFE, and polypropylene are suitable. A hollow fiber membrane, which is widely used for filtration purposes, may be used as the tube 6.

[0036] The pipe 6 is provided with a mechanism for receiving a water supply, such as a tank that stores water and a pump that transports water from the tank to the pipe.

[0037] Figures 5 to 7 show a vest 20 using a cooling layer 1. As shown in Figures 5 and 7, an isolating layer 7a is arranged on the skin side of the wearer. In addition to the skin side of the wearer, an isolating layer 7b is also arranged on the outer surface of the vest at a position corresponding to the shoulders of the vest. As described later, when a jacket 30 is worn over the vest, the outer shoulders of the vest will be in contact with the inside of the jacket 30, so this is to prevent the inside of the jacket 30 from getting wet with water from the moisture retention layers (5a, 5b).

[0038] On the outer surface of the vest, the evaporation assistance layer 8 is placed over as large an area as possible, except for the area where the isolation layer is placed to prevent the inside of the jacket 30 from getting wet as described above. The isolation layers (7a, 7b) and the evaporation assistance layer 8 sandwich the moisture retention layers (5a, 5b).

[0039] 8 and 9 show the jacket 30 worn over the vest 20. The jacket 30 is equipped with a fan 35 for blowing outside air into the jacket 30. The fan 35 rotates using battery power. The battery is stored, for example, in a battery holder 36 so that power is always available when the jacket is worn. As shown in FIG. 8, the wind emitted from the fan 35 flows toward the cooling layer of the vest. The cooling layer of the vest allows air to pass through easily, and the heat of vaporization generated from the cooling layer cools the wearer's body.

[0040] In Example 1, a cooling layer is attached to a vest, and a jacket equipped with a fan is worn over the vest to blow air onto the cooling layer. Alternatively, a jacket equipped with a fan may be pre-attached to it in the same structure as the vest shown in Example 1 to form an integrated unit. EXAMPLES

[0041] Example 2 is an example relating to a means for supplying water to the moisture retention layer. In Example 2, as shown in Figures 10 and 11, water is supplied to the moisture retention layer by spraying water using a spray-like mechanism.

[0042] The jacket 30 is provided with an outlet hole 38. Water is sprayed from the outlet hole 38 toward the moisture retention layer 5 or the evaporation assistance layer 8 of the vest 30. The outlet hole 38 is equipped with a spray mechanism (not shown). Water is supplied to the spray mechanism via a hose (not shown). The water supplied to the spray mechanism is sprayed from the outlet hole 38.

[0043] When water is supplied to the moisture retaining layer by spraying using a spray-like mechanism, the water evaporates during spraying, further cooling the surrounding air. EXAMPLES

[0044] FIG. 12 shows a third embodiment. In the third embodiment, the cooling layer 1 cools the cooling target 10 and the cooling target 12 at the same time. The cooling target 10 and the cooling target 11 are arranged with the cooling layer 1 in between. A waterproof and highly heat-conductive layer 15 made of a highly heat-conductive material is arranged between the cooling layer 1 and the cooling target 11. By interposing a layer made of a highly heat-conductive material (e.g., a fabric containing aluminum or titanium), heat is conducted to the cooling target 11 over a wide area in a short time. For example, in a cooling garment, if the cooling target indicated by the reference numeral 10 is the wearer's body, the reference numeral 11 is the outer surface of the garment. The wearer of such a garment can feel the coolness of the body as well as the coolness of the cooling garment when touched from the outside.

[0045] The black arrows in Figure 12(a), (b), and (c) indicate the flow of air. The air flowing toward cooling layer 1 passes through it due to the excellent breathability of cooling layer 1, changes direction when it hits the object to be cooled 10, and flows toward cooling layer 1 again. The air toward cooling layer 1 passes through the cooling layer and hits highly thermally conductive layer 15. The area indicated by C in the figure is cooled by cooling layer 1. The temperature of highly thermally conductive layer 15 drops when the air that has passed through the cooling layer and been cooled, and the cooled air at the area indicated by C in the figure, come into contact with the highly thermally conductive layer and the cooling layer.

[0046] In (b), the cooling layer 1 is tilted by the air circulating inside the garment. In (c), the cooling layer 1 is fluttering and swaying due to the air circulating inside the garment. As the cooling layer 1 tilts and flutters in this way, it partially comes into contact with and separates from the high thermal conductivity layer. The temperature drops especially in the areas of the high thermal conductivity layer that the cooling layer 1 comes into contact with. In addition, water adheres to the areas of the high thermal conductivity layer that the cooling layer 1 comes into contact with. The water that adheres to the high thermal conductivity layer evaporates, further cooling the high thermal conductivity layer. EXAMPLES

[0047] Example 4 is an example related to a fan. By sending air to the cooling layer 1, the water held by the moisture retention layer 5 evaporates, and the surrounding air can be cooled. A fan is used to send air to the cooling layer. In (a) and (b) of FIG. 13, the cooling layer 1 and the cooled air indicated by C in the figure are sandwiched between the cooling target 10 and the waterproof and highly thermally conductive layer 15.

[0048] 13(a), one fan 33 is attached to the object to be cooled 10 and one to the waterproof, highly thermally conductive layer 15. As shown by the black arrows in the figure, the fan 33 blows air inward from the outside of the object to be cooled 10 and the outside of the waterproof, highly thermally conductive layer 15. The air blown inward from the outside flows toward the cooling layer 1.

[0049] In FIG. 13(b), a double-sided intake fan 34 is attached across the object to be cooled 10 and the waterproof, highly thermally conductive layer 15. As indicated by the black arrows in the figure, the double-sided intake fan 34 takes in air from both the outside of 10 and the outside of 15, and exhausts it inward. The double-sided intake fan 34 is a sirocco fan with these characteristics, and can supply and exhaust air more powerfully than when two fans are used as shown in (a). When a double-sided intake fan is used, weight and costs can be reduced because only one fan is required. EXAMPLES

[0050] In the fifth embodiment, the object to be cooled 12 is a device such as a personal computer that uses integrated circuits and requires active heat dissipation. The cooling layer 1 according to the present application can easily and effectively cool such an apparatus. However, it is strictly prohibited for such an apparatus to get wet. Therefore, the waterproof and highly thermally conductive layer 15 completely prevents water or water vapor from moving from the cooling layer 1 to the object to be cooled 12.

[0051] Example 5 is shown in Figure 14. As shown in Figure 14, a waterproof, highly thermally conductive layer 15 is provided between the object to be cooled 12 and the cooling layer 1. The waterproof, highly thermally conductive layer 15 is preferably in a bag-like form so that water or water vapor does not move to the object to be cooled. The bag-like waterproof, highly thermally conductive layer 15 has two holes 17, which serve as entrances and exits for the air around the cooling layer 1. [Explanation of symbols]
