Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of parts for cooling and heating clothing, and more particularly to a constant temperature refrigeration device and cooling and heating clothing. [Background technology]
[0002] The refrigeration unit is the main component of the cooling suit. The cooling unit is attached to the cooling suit and is used to lower a person's body temperature and dissipate heat.
[0003] Current cooling and heating suits use a refrigeration system, which mainly uses phase-change materials to freeze the clothes in a refrigerator, storing the cold. After storing the cold, the clothes are put into the cooling and heating suit.
[0004] However, the refrigeration storage method has a short duration and consumes the cold source relatively quickly. To extend the duration, the only way is to increase the weight of the refrigeration device, which results in a large weight. Summary of the Invention [Problem to be solved by the invention]

[Means for solving the problem]

[0008] Preferably, a protective cover is provided on the axial flow fan and the fan grill, and the protective cover has a hollowed-out structure.

[Effects of the Invention]
[0016] This invention provides a constant-temperature refrigeration device and cooling / heating clothing that provides continuous cooling. The constant-temperature refrigeration device uses a Peltier element to provide continuous cooling, extending the cooling duration, increasing thermal effusivity, and improving energy utilization.

[0019] In order to clarify the technical problems to be solved, the technical contents adopted, and the technical effects achieved by the present invention, the present invention will be described in more detail below with reference to the drawings and examples. It will be understood that the specific examples described herein are merely for the purpose of illustrating the present invention and are not intended to limit the present invention. For ease of explanation, the drawings only show a portion of the contents related to the present invention, rather than all of the contents.
[0020] Example 1 As shown in FIGS. 1 to 3, the embodiment of the present invention provides a constant temperature refrigeration device that continuously cools, including a bag body 1, a cold conduction plate 2, a freezing sheet 3, heat dissipation fins 4, and an axial flow fan 5.
[0021] The bag 1 is made of a phase-change material. Phase-change materials (PCMs) absorb large amounts of heat when they change phase (from solid to liquid) within a temperature range close to the human body's comfort temperature (usually around 28-32°C). This property allows them to provide instant cooling when the body begins to heat up, making them suitable for clothing. The phase-change material realizes constant-temperature refrigeration, enhancing comfort on the body surface. In this embodiment, the phase-change material can be paraffin, fatty acid, or polyethylene glycol.
[0022] A cold conduction plate 2 is provided inside the bag 1 to conduct cold and fix the freezing sheet 3, and the cold conduction plate 2 can expand the freezing surface. The cold conduction plate 2 can be made of an aluminum alloy plate or a stainless steel plate.
[0023] The freezing sheet 3 is attached to one side of the bag 1 and is a Peltier freezing sheet with a freezing surface and a heat-dissipating surface. In this embodiment, the freezing surface of the freezing sheet 3 is in close contact with the cold-conducting plate 2, which is advantageous for cold conduction, increasing the thermal effusivity and energy utilization rate. The temperature of the bag 1 is reduced by the freezing sheet 3 and the cold-conducting plate 2. The heat-dissipating surface of the freezing sheet 3 is fitted with heat-dissipating fins 4, which are plate-shaped or irregularly shaped (e.g., sunflower-shaped as shown in Figure 1 ) and made of aluminum alloy or stainless steel, which is advantageous for dissipating heat from the heat-dissipating surface of the freezing sheet 3. This device uses a Peltier freezing sheet to provide continuous cooling, extend the freezing duration, increase the thermal effusivity, and improve energy utilization rate. Furthermore, the lightweight Peltier freezing sheet reduces the weight of the refrigeration device.
[0024] An axial fan 5 is installed on the heat dissipation fins 4. The axial fan 5 blows out heat from the heat dissipation surface of the freezing sheet 3, improving heat dissipation efficiency. The axial fan 5 can be a stage-adjustable fan, allowing the wind power to be adjusted as needed.
[0025] A fan grill 6 is attached to the circumferential outside of the axial fan 5, the fan grill 6 is fixedly connected to the heat dissipation fins 4, and a plurality of air outlets are provided in the circumferential direction of the fan grill 6. The fan grill 6 corresponds to a housing for the axial fan 5, and can blow out the air blown by the axial fan 5 in the circumferential direction, thereby enhancing the heat dissipation effect.
[0026] Based on the above solution, a protective cover 7 is provided on the axial fan 5 and the fan grille 6, and the protective cover 7 has a hollowed-out structure. Specifically, the protective cover 7 has uniformly distributed radial stop bars. The protective cover 7 not only prevents foreign objects from entering and affecting the operation of the axial fan 5, but also prevents heat dissipation.
[0027] The operating principle of the constant temperature refrigeration device of this invention is as follows: the freezing surface of the freezing sheet 3 provides a cold source, which is then transferred to the cold conduction plate 2, and the temperature is then lowered to the outside through the bag 1. This can be applied to clothing, and the bag 1 can come into contact with human skin. The heat dissipation surface of the freezing sheet 3 dissipates heat generated by the freezing sheet 3 through the axial fan 5 and fan grill 6, thereby achieving heat dissipation. When installed, the axial fan 5, fan grill 6, and protective cover 7 face outward to facilitate heat dissipation.
[0028] Example 2 As shown in Figure 4, the cooling and heating suit provided by the embodiment of the present invention includes a constant temperature refrigeration device 8 that provides continuous cooling according to any embodiment of the present invention, and the constant temperature refrigeration device 8 that provides continuous cooling is attached to the cooling and heating suit 9. The freezing side of the bag body 1 of the constant temperature refrigeration device 8 faces the human body and can come into contact with the human skin.
[0029] The cooling and heating suit 9 has a mesh opening at the position where the constant temperature refrigeration device 8 that continuously cools the body is attached, and the axial flow fan 5 faces the mesh opening. Specifically, the axial flow fan 5, fan grill 6, and protective cover 7 face the mesh opening to facilitate heat dissipation.
[0030] Based on the above solution, a power supply is provided individually for each constant temperature refrigeration device 8 that continues to cool, or a centralized power supply is provided in the cooling and heating suit 9, and each constant temperature refrigeration device 8 that continues to cool is electrically connected to the centralized power supply, and multiple constant temperature refrigeration devices 8 on the cooling and heating suit 9 are connected to the centralized power supply. The freezing sheet 3 and axial fan 5 of the constant temperature refrigeration device 8 are electrically connected to a power supply, and the power supply supplies power to the freezing sheet 3 and the axial fan 5.
[0031] Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and are not limiting, and although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that amending the technical solutions described in the above embodiments or replacing some or all of the components with equivalents will not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present invention.
