[0002] Currently, working in high-temperature environments requires air conditioning, fans, and other tools to cool the office environment. However, these methods are energy-intensive, require large spaces, and suffer significant energy loss, making them uneconomical. Some people install miniature fans in their clothing to cool themselves, but the drawback is that the air blown out is at the same temperature as the environment, resulting in poor cooling. Others incorporate ice water and pumps inside their clothing for circulation, but this is initially too cold, doesn't last long, and then heats up again, requiring the addition of ice and making it difficult to preserve. Still others use semiconductor cooling sheets for cooling, but this has the disadvantages of limited cooling area, high energy consumption, and short battery life. Utility Model Content

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 6 As shown in this embodiment, a wearable cooling system includes clothing 1, compressor 2, condenser 3, evaporator 4, and back cover 5. A support plate 6 is bent into shape in the middle of the back cover 5. The compressor 2 is fixed on the support plate 6. The condenser 3 is located below the compressor 2. A refrigerant capillary tube 7 is provided on one side of the condenser 3. The inlet end of the refrigerant capillary tube 7 is connected to the outlet end of the condenser 3, and the outlet end of the refrigerant capillary tube 7 is connected to the inlet end of the evaporator 4. An air suction pipe 8 is connected to the inlet end of the compressor 2, and the outlet end of the evaporator 4 is connected to the air suction pipe 8. An exhaust pipe 9 is connected between the outlet end of the compressor 2 and the inlet end of the condenser 3. An outer shell 10 is covered on the back cover 5. The outer shell 10 and the back cover 5 form a backpack. A cooling fan 11 is installed on the outer shell 10. The cooling fan 11 is located in front of the condenser 3. The evaporator 4 is distributed on the front and back sides of the clothing 1.

[0027] The back panel is made of aluminum alloy and has several ventilation holes 25 distributed vertically. The back panel fits against the back of the person and, combined with the heat absorption capacity of aluminum alloy, can carry away heat.

[0028] After the compressor 2 compresses the low-temperature liquid refrigerant to a high temperature and pressure, it dissipates heat through thermal interaction on the condenser 3. The cooling fan 11 blows air to carry the high temperature on the condenser 3 out of the backpack. The cooled refrigerant passes through the refrigerant capillary tube 7 and then becomes gaseous, achieving pressure and temperature reduction. It then comes into contact with the human body and cools down along the evaporator tube 4 close to the human body. The liquid refrigerant, after its temperature rises, re-enters the compressor 2, and the above cooling process is repeated. During this process, the controller 12 controls the operation of each part. The evaporator tube 4 is evenly distributed inside the clothing 1, resulting in a high degree of temperature reduction balance.

[0029] A controller 12 is installed on one side of the compressor 2. The controller 12 controls the operation of the compressor 2, condenser 3 and refrigerant capillary tube 7. A control board 13 is installed below the controller 12. The control board 13 is equipped with a power plug 14 and a control knob 15. In addition, a pocket 16 is provided on the front of the garment 1. A rechargeable battery 17 is placed in the pocket 16. The controller 12 is electrically connected to the rechargeable battery 17. After the user puts on the garment 1, he / she can control the cooling temperature and switch on and off from the control knob 15 on the side. The rechargeable battery 17 is installed in the pocket 16 so that the power and charging status can be seen at a glance. It can be charged through the power plug 14. Through the information transmission of the control board 13, the controller 12 controls the operation of various functional components. Moreover, the rechargeable battery 17 uses a 24V DC safe power supply. It can achieve 4 hours of use after charging for 2 hours at the lowest power. The rechargeable battery 17 can be easily replaced so that the use is uninterrupted.

[0030] During control, the controller 12 adjusts the speed of the compressor 2 and the cooling fan 11 by using the control knob 15, which has 4 positions and 3 settings: 0 - off, 1 - low power operation, 2 - medium power operation, and 3 - high power operation. When the control knob 15 is in the off position, both the compressor 2 and the cooling fan 11 are stationary. When the control knob 15 is in the 1, 2, or 3 position, the controller 12 adjusts the speed of the compressor 2 and the cooling fan 11 according to the different settings. Through power adjustment, the evaporation temperature is adjusted, thereby controlling the temperature of the evaporation tube 4 inside the garment 1.

[0031] The front and rear sides of the garment 1 are connected by straps 18, which are connected by buckles. The outer edge of the back shell 5 is provided with a zipper 19, which is fixed to the rear of the garment 1. The zipper 19 is connected to the outer shell 10 by teeth. The garment 1 is put on the body from top to bottom, and then the straps 18 on both sides are fastened by buckles. The cooling components on the back are all concentrated inside the backpack and can be installed, maintained and updated by opening the zipper 19.

[0032] The lower end of the compressor 2 is fixed with a body connecting plate 20. The body connecting plate 20 is locked to the support plate 6 with screws. The body connecting plate 20 is first welded to the compressor 2 so that the compressor 2 can be installed in different positions through the body connecting plate 20.

[0033] The inlet end of condenser 3 is bent inward along the horizontal direction, and the outlet end of condenser 3 is bent upward along the vertical direction. The inlet and outlet of condenser 3 are tucked inward by bending, so as not to affect the volume space of the backpack.

[0034] The lower end of the back shell 5 is bent into a base plate 21, which is located in the middle of the lower end of the condenser 3. The condenser 3 is locked to the base plate 21 by screws. Both the support plate 6 and the base plate 21 are directly bent from the back shell 5, without the need for additional modules, thus saving resources.

[0035] The condenser 3 has straight pipe structures 22 on both sides, which are hollow. The hollow part of the straight pipe structure 22 is connected to the outside in the vertical direction. Several condensing connecting plates 23 are distributed vertically between the two straight pipe structures 22. Heat dissipation fins 24 are arranged between the condensing connecting plates 23. The heat dissipation fins 24 are wavy. After the high temperature liquid refrigerant enters the straight pipe structure 22 on one side of the condenser 3, it flows to the other side along the horizontally distributed condensing connecting plates. Under the action of the heat dissipation fins 24 in the middle, it interacts with the outside heat. The wavy shape makes it easier to cool down.

[0036] Compressor 2 is used to pressurize and heat up the liquid refrigerant. It is located inside the backpack. During operation, the low-temperature and low-pressure gaseous refrigerant is drawn into compressor 2 and forcefully compressed into a high-temperature and high-pressure gas. The compression process causes the refrigerant molecules to move violently and the temperature to rise significantly. Its function is to create conditions for the refrigerant to release heat, and the high-temperature gas can more easily dissipate heat to the environment.

[0037] The condenser 3 is used for the exothermic liquefaction of gaseous refrigerant. It is located inside the backpack. During operation, the high-temperature and high-pressure gaseous refrigerant flows into the condenser 3. The cooling fan 11 blows air over the heat dissipation fins 24 of the condenser 3, carrying away the heat of the refrigerant. As the heat is released into the air, the high-temperature and high-pressure gaseous refrigerant cools and condenses into a medium-temperature and high-pressure liquid refrigerant. Its function is to release the heat absorbed from the human body and the heat generated by the compressor 2 into the environment.

[0038] The cooling fan 11 is used to cool the condenser 3. It is located inside the backpack. During operation, the cooling fan 11 blows air over the heat dissipation fins 24 of the condenser 3, carrying away the heat of the refrigerant. Its function is to create airflow conditions for the refrigerant in the condenser 3 to release heat.

[0039] The refrigerant capillary tube 7 is used to reduce the pressure and temperature of liquid refrigerant to turn it into gaseous refrigerant. Its position is inside the backpack. During operation, the medium-temperature and high-pressure liquid refrigerant flows through the slender refrigerant capillary tube 7, causing a huge pressure drop. This causes the refrigerant pressure to drop sharply. The effect is that through the adiabatic expansion process (sudden pressure drop and sudden volume increase), the temperature of the liquid refrigerant drops sharply, turning it into a low-temperature and low-pressure gas-liquid mixture (mostly liquid with a small amount of flash gas).

[0040] Evaporator tube 4 is used for heat absorption and vaporization. It is located inside the clothing 1. During operation, a low-temperature, low-pressure gas-liquid mixture of refrigerant enters the evaporator tube 4 of the clothing 1. The refrigerant absorbs the heat from the human body and evaporates (boils) from a liquid state into a low-temperature, low-pressure gaseous refrigerant. Its function is to absorb the heat from the human body to achieve the purpose of cooling. After absorbing heat, the refrigerant turns back into a low-temperature, low-pressure gas.

[0041] Back to the starting point:

[0042] The low-temperature, low-pressure gaseous refrigerant is drawn back into compressor 2 to begin the next cycle. When passing through the human body, it absorbs the body's heat, and the liquid refrigerant becomes a low-temperature, low-pressure gaseous refrigerant, which is then drawn back into compressor 2 to begin the next cycle.

[0043] It should be stated that the above specific embodiments are merely preferred embodiments of this utility model and the technical principles used therein. Within the scope of the technology disclosed in this utility model, any changes or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
