Abstract
Description
Technical Field
[0001] This utility model belongs to the field of footwear technology, and specifically relates to a running shoe with heat dissipation effect. Background Technology
[0002] Running shoes are commonly used everyday sports wear. During long-distance running, the heel and forefoot of the feet easily generate a lot of heat due to friction and compression of the sole. The temperature range of the heat generated on the sole is between 42℃ and 45℃. As the running time goes on, the heat generated on the sole cannot be effectively dissipated, causing the temperature of the sole to continue to rise, which brings obvious discomfort to the user. In order to alleviate this problem, various shoes that can cool down and dissipate heat have appeared on the market.
[0003] Existing technologies can be broadly categorized into two types. One type involves altering the structure of the shoe cavity to allow for ventilation and air exchange. This technology is relatively simple but has low heat exchange efficiency and poor heat dissipation. The other type employs a vapor compression refrigeration system. These shoes typically require small devices such as condensers, evaporators, and piston rods to be installed in the sole. While this can provide some cooling, the shoes have a complex structure, high production costs, and these devices increase the shoe's weight, making running difficult and causing wear and tear on these devices during exercise. This results in frequent replacement of the small devices inside the sole, leading to high maintenance costs.
[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention
[0005] The purpose of this invention is to provide a running shoe with a simple structure, good heat dissipation effect, and good heat exchange effect.
[0006] To achieve the above objectives, this utility model adopts the following technical solution:
[0007] A running shoe with heat dissipation function, comprising:
[0008] The sole has a first fluid channel inside it that can absorb the heat generated by the sole.
[0009] The shoe upper is provided with a second fluid channel capable of dissipating heat, and the second fluid channel is connected to the first fluid channel;
[0010] A phase change fluid is filled in a first fluid channel. The phase change fluid is used to absorb heat from the sole of the shoe and vaporize to flow to a second fluid channel on the upper of the shoe, and then re-liquefy and flow back to the first fluid channel.
[0011] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:
[0012] This invention relates to a running shoe with heat dissipation capabilities. A phase change liquid (PCL) fills the first fluid channel in the sole. The PCL absorbs heat from the sole, vaporizes, and flows to a second fluid channel on the upper. It then liquefies and flows back to the first fluid channel. Since the PCL absorbs heat during vaporization, while the second fluid channel dissipates heat, when heat is generated in the sole, the PCL absorbs heat and vaporizes, effectively reducing the sole temperature. The vaporized gas flows to the second fluid channel on the upper, where it liquefies upon cooling and releases heat. The gas then reverts to a liquid within the second fluid channel, and the liquid returns to the first fluid channel in the sole via gravity or other mechanisms, forming a closed liquid-gas circulation system. In this way, the PCL effectively transfers heat generated in the sole to the upper for release, achieving continuous heat dissipation and temperature regulation. This invention features a simple structure and excellent heat exchange performance.
[0013] Furthermore, the boiling point of the phase change liquid is 30℃-50℃.
[0014] When the human body is running normally, the temperature range of the heat generated by the sole of the shoe is approximately 42℃-45℃. The boiling point of the phase change liquid is 30℃-50℃. This allows the phase change liquid in the first fluid channel to absorb the heat from the sole and vaporize, rising and flowing to the second fluid channel on the shoe surface. It then exchanges heat with the outside air, re-liquefies, and flows back. This continuous circulation during exercise dissipates heat from the sole, resulting in a good heat exchange effect.
[0015] Furthermore, the first fluid channel is configured as a first heat-conducting pipe, which is distributed at the heel and forefoot of the sole, extending from the heel to the forefoot; the second fluid channel is configured as a second heat-conducting pipe, which is distributed at the upper of the corresponding heel and the upper of the corresponding forefoot, and the second heat-conducting pipe is connected to the first heat-conducting pipe.
[0016] The first fluid channel is configured as a first heat-conducting pipe, which allows the first heat-conducting pipe to be pre-installed in the sole during the production of the shoe sole, making production simple and convenient; the second fluid channel is configured as a second heat-conducting pipe, which can be placed on the outside of the shoe upper to improve the heat dissipation effect.
[0017] Furthermore, the first heat-conducting pipes are evenly distributed, and the first heat-conducting pipes are distributed in a grid pattern.
[0018] The first heat conduction pipes are arranged in a grid pattern, that is, the first heat conduction pipes are arranged in an interlaced and interconnected manner, thereby increasing the heat absorption area and further improving the heat dissipation effect.
[0019] Furthermore, the second heat-conducting pipes are arranged alternately on the upper parts of the shoe at the corresponding heel and the corresponding forefoot.
[0020] The staggered arrangement of the second heat conduction pipes allows for a larger flow space for the vaporized phase change liquid, increasing the area for heat exchange between the vaporized phase change liquid and the air.
[0021] Furthermore, the portions of the first heat-conducting pipe located at the heel and forefoot of the shoe sole are both recessed in shape, with a lower center and higher edges.
[0022] The first heat conduction pipe, located at the heel and forefoot of the sole, has a recessed shape that is lower in the middle and higher around the edges. This effectively prevents the phase change liquid from being blocked at the connection between the first and second heat conduction pipes due to surface tension, thus preventing the vaporized phase change liquid from flowing into the outer second heat conduction pipe.
[0023] Furthermore, both the first and second heat-conducting pipes are made of corrosion-resistant materials.
[0024] Because phase change fluid is corrosive, both the first and second heat conduction pipes are made of corrosion-resistant materials, which can improve their service life.
[0025] Furthermore, it also includes a heat-concentrating sheet disposed in the sole of the shoe around the first heat-conducting pipe to concentrate and conduct heat from the sole to the first heat-conducting pipe.
[0026] The heat-concentrating sheet gathers the heat from the sole of the shoe and conducts it to the first heat-conducting pipe, thereby accelerating the absorption of heat from the sole.
[0027] Furthermore, the heat-absorbing sheet is configured as a thin copper foil film for heat absorption covering the outside of the first heat-conducting pipe.
[0028] A thin copper foil film is wrapped around the outside of the first heat pipe, which can accelerate the absorption of heat by the sole of the shoe.
[0029] Furthermore, the sole is provided with a side wall, and the second heat-conducting pipe extends from the upper to the side wall and communicates with the first heat-conducting pipe. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] like Figures 1 to 3 As shown, a running shoe with heat dissipation effect includes a sole 10 and an upper 20 located on the sole 10. The sole 10 includes a heel portion 30 corresponding to the heel and a forefoot portion 40 corresponding to the forefoot. The sole 10 has a first fluid channel that can absorb the heat generated by the sole 10, and the upper 20 has a second fluid channel that can dissipate heat. Specifically, the first fluid channel is configured as a first heat-conducting pipe, which is mainly distributed at the heel portion 30 and the forefoot portion 40 of the sole 10, extending from the heel portion 30 to the forefoot portion 40. The second fluid channel is configured as a second heat-conducting pipe, which is distributed at the upper 20 corresponding to the heel portion 30 and the upper 20 corresponding to the forefoot portion 40, and the second heat-conducting pipe is connected to the first heat-conducting pipe.
[0040] The first heat-conducting pipe 1 is laterally distributed within the sole 10. Specifically, in this embodiment, the portions of the first heat-conducting pipe 1 located at the heel 30 and forefoot 40 are arranged in a grid pattern, intersecting and interconnected. A second heat-conducting pipe 2 is fixedly provided on the outer side of the upper 20. The second heat-conducting pipe 2 includes rear conduits 21 located on both sides of the upper 20 at the heel 30 and front conduits 22 located on both sides of the upper 20 at the forefoot 40. Sidewalls are provided around the perimeter of the sole 10. The two sides of the first heat-conducting pipe 1, corresponding to the heel 30, protrude from the sole 10 and connect to the bottom of the rear conduit 21. The two sides of the first heat-conducting pipe 1, corresponding to the forefoot 40, protrude from the sole 10 and connect to the bottom of the front conduit 22. The first heat-conducting pipe 1 is filled with a phase change fluid for absorbing heat. The boiling point of the phase change fluid is 30℃-50℃. Specifically, in this utility model, the phase change fluid is the commercially available Opteon™ SF33 (chemical name: HFO-1336mzz-Z) fluid. Due to the special chemical properties of the phase change fluid, the boiling point of the phase change fluid is 30℃-50℃.
[0041] During normal running, the heel (30) and forefoot (40) of the foot easily generate a large amount of heat due to friction and compression of the shoe sole (10). The temperature range of the heat generated by the foot is approximately 42℃-45℃, which exceeds the minimum boiling point threshold of the phase change fluid. The heat from the foot is transferred to the shoe sole (10), causing the phase change fluid in the first heat conduction pipe (1) to absorb the heat from the foot and partially vaporize and rise. The partially vaporized phase change fluid is squeezed outward under the pressure of continuous foot movement, and simultaneously, propelled by the remaining unvaporized liquid, flows along both sides of the first heat conduction pipe (1) to the second heat conduction pipe (2), and rises to the top of the second heat conduction pipe (2). Specifically, the phase change fluid at the heel (30) liquefies and flows towards the rear conduit (21), while the phase change fluid at the forefoot (40) liquefies and flows towards the front conduit (22). The flow direction is as follows: since both the rear conduit 21 and the front conduit 22 are located on the outside of the shoe upper 20, that is, the second heat conduction pipe 2 is located on the outside of the shoe upper 20, the vaporized phase change liquid in the second heat conduction pipe 2 will exchange heat with the outside air when the human body moves, and continuously transfer heat to the outside air, so that the temperature of the vaporized phase change liquid in the second heat conduction pipe 2 gradually decreases. When the temperature of the vaporized phase change liquid is lower than its own maximum boiling point threshold, it will liquefy. The liquefied phase change liquid in the second heat conduction pipe 2 flows back to the first heat conduction pipe 1 of the shoe sole 10 due to its own weight, and can continuously circulate and dissipate heat from the shoe sole 10 during exercise. It should be noted that the phase change liquid of this utility model can also be other conventional phase change liquids that can be purchased on the market, as long as they can achieve the above effect.
[0042] Correspondingly, the first heat conduction pipe 1 is fixed inside the sole 10 in a conventional manner, such as by embedding, and the second heat conduction pipe 2 is fixed on the outside of the upper 20 in a conventional manner, such as by adhesion or embedding. The wall thickness of the first heat conduction pipe 1 is made as thin as possible while ensuring its strength, so as not to affect the heat absorption effect. The wall thickness of the second heat conduction pipe 2 is made as thin as possible while ensuring its strength, so as not to affect the heat dissipation effect.
[0043] Preferably, since the phase change fluid has certain corrosive properties, the first heat conduction pipe 1 and the second heat conduction pipe 2 of this invention are both made of conventional corrosion-resistant materials in the art, such as chloroprene rubber or polytetrafluoroethylene, which can extend the service life of the second heat conduction pipe 2 and the first heat conduction pipe 1.
[0044] Preferred, such as Figure 1 As shown, the outer side of the first heat conduction pipe 1 is covered with a heat-absorbing sheet. Preferably, in this embodiment, the heat-absorbing sheet is a copper foil film. The copper foil film has the function of absorbing heat. The heat of the shoe sole 10 is first absorbed by the copper foil film covering the first heat conduction pipe 1 and then transferred to the phase change liquid inside the first heat conduction pipe 1. This can accelerate the absorption of heat by the shoe sole 10.
[0045] Preferably, the rear conduit 21 is arranged vertically and extends upward to a position near the top of the shoe upper 20. The rear conduits 21 are arranged to intersect and are interconnected. The front conduits 22 are arranged vertically and extend upward to a position near the top of the shoe upper 20. The front conduits 22 are arranged to intersect and are interconnected. This arrangement can increase the contact area between the second heat conduction pipe 2 and the air, resulting in a better heat exchange effect. It can also allow for a larger flow space for the vaporized phase change liquid, increasing the area for heat exchange between the vaporized phase change liquid and the air.
[0046] It should be noted that, due to the surface tension of the phase change liquid, and the limitation of the sole 10 in this invention, the diameter of the first heat-conducting pipe 1 is relatively small. To prevent the phase change liquid from being blocked at the connection between the first heat-conducting pipe 1 and the second heat-conducting pipe 2 due to surface tension, thus preventing the vaporized phase change liquid from flowing into the outer second heat-conducting pipe 2; preferably, as Figure 1 and Figure 3As shown, the portion of the first heat-conducting pipe 1 located at the heel 30 has a recessed shape that is lower in the middle and higher around the edges, and the portion of the first heat-conducting pipe 1 located at the forefoot 40 also has a recessed shape that is lower in the middle and higher around the edges. This design ensures that the phase change fluid located at the heel 30 can always flow into the recessed area of the heel, and the phase change fluid located at the forefoot 40 can always flow into the recessed area of the forefoot. This effectively avoids blockage caused by the tension of the phase change fluid adhering to the connection between the first heat-conducting pipe 1 and the second heat-conducting pipe 2, which would prevent the vaporized phase change fluid from flowing into the outer second heat-conducting pipe 2.
[0047] This invention relates to a running shoe with heat dissipation capabilities. The first fluid channel of the sole 10 is filled with a phase change liquid. This phase change liquid absorbs heat from the sole 10, vaporizes, and flows to the second fluid channel of the upper 20. It then liquefies and flows back to the first fluid channel. Since the vaporization of the phase change liquid absorbs heat, while the second fluid channel dissipates heat, when the sole 10 generates heat, the phase change liquid absorbs heat and vaporizes, effectively reducing the temperature of the sole 10. The vaporized gas flows to the second fluid channel of the upper 20, where it liquefies upon cooling and releases heat. The gas then reverts to a liquid within the second fluid channel, and the liquid returns to the first fluid channel of the sole 10 via gravity or other mechanisms, forming a closed liquid-gas circulation system. In this way, the phase change liquid effectively transfers the heat generated by the sole 10 to the upper 20 for release, achieving continuous heat dissipation and temperature regulation of the sole 10. This invention features a simple structure and excellent heat exchange performance.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
