[0002] Most protective suits on the market only have a single cooling function, which cannot accommodate more application scenarios. They are equipped with only a single cooling pad and a single heat sink. However, in high-temperature environments, their cooling capacity is insufficient, resulting in a poor experience. In addition, the heat sink uses one-sided airflow, and the airflow speed weakens at the heat sink outlet, causing heat to accumulate and not dissipate in a timely and effective manner. Furthermore, most water-cooled protective suits on the market have a one-way circulating water system. During operation, the cooling / heating effect is often obvious in the first half near the water outlet, but there is no noticeable effect in the second half, resulting in an uneven body temperature and failing to provide a comfortable temperature for the wearer.

Detailed Implementation

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 This embodiment discloses a water circulation hot and cold switching device 1, which includes a water cooling head 11, a heat conduction device, a ventilation device, and a control device; The water cooling head 11 includes an inlet end, an outlet end, and several sets of temperature-conducting end faces. The inlet end and the outlet end are connected to form a water passage for the return of cold water or hot water. The heat transfer device includes several sets of cooling chips 12 and radiators 13. Each of the heat-conducting end faces is sequentially provided with a set of cooling chips 12 and a set of radiators 13 in heat-conducting contact. The cooling chips 12 are electrically connected to the control device to realize heat transfer. The ventilation device includes a blower mechanism 14 and an exhaust mechanism 15 respectively disposed on both sides of the heat conduction device. The blower mechanism 14 and the exhaust mechanism 15 are both disposed corresponding to the radiator 13 to form a heat dissipation path.

[0018] Specifically, users can switch between cooling and heating modes according to actual usage to suit different environments. Whether working or exercising outdoors in high or low temperatures, or in an indoor environment without air conditioning, the device can provide a comfortable temperature for the wearer. For example, in hot environments, it helps the body lower its temperature, removes heat from the body surface, and lowers the core temperature, keeping the wearer cool and comfortable and preventing heatstroke, heat exhaustion, and heat stress, allowing for continuous work in hot environments. Similarly, in cold environments, it helps the body maintain its temperature, retains heat from the body surface, and prevents the core temperature from dropping too low, thus preventing frostbite and cold stress, keeping the wearer warm and comfortable and allowing for continuous work in cold environments.

[0019] In this embodiment, the water cooling head 11 includes two sets of temperature-conducting end faces on its upper and lower surfaces. Each set of temperature-conducting end faces is sequentially and temperature-conductingly contacted with a set of cooling fins 12 and a set of radiators 13, so as to effectively increase the conduction of cold or heat on the water cooling head 11. The cooling capacity can reach up to 95W. Even in high-temperature environments, the cooling capacity is still sufficient to ensure the best experience. Furthermore, the air blowing mechanism 14 and the exhaust mechanism 15 are used to ensure that the airflow and air speed to the radiator 13 are constant and do not decrease, preventing heat from accumulating at the air outlet and improving heat dissipation efficiency.

[0020] Preferably, the ventilation device further includes several sets of air guide structures 16, each set of which includes several sets of air guide plates. The air guide plates are inclined from the blower mechanism 14 toward the radiator 13 or from the radiator 13 toward the exhaust mechanism 15 to guide the inflow or outflow of air. Specifically, when the blower mechanism 14 blows air to generate inflow, the inflow air is blown along the air guide plates to the radiator 13 to dissipate heat and cool it down. The outflow air carrying the heat of the radiator 13 is discharged along the air guide plates through the exhaust mechanism 15, thereby achieving continuous and efficient blowing and cooling of the radiator 13.

[0021] Furthermore, the heat dissipation area of ​​the radiator 13 is larger than the heat transfer area of ​​the cooling chip 12. The heat dissipation surface of the radiator 13 is in thermal contact with the heat transfer surface of the cooling chip 12, ensuring that the radiator 13 quickly absorbs the heat from the cooling chip 12 and greatly increases the heat dissipation area of ​​the radiator 13, effectively improving the heat dissipation efficiency and effect.

[0022] Furthermore, the radiator 13 is a finned radiator 13, which includes several sets of heat dissipation fins with gaps. Ventilation gaps are formed between adjacent heat dissipation fins. When the blower mechanism 14 blows air to generate inflow air, the inflow air enters the ventilation gap to efficiently remove the heat from the heat dissipation fins, further increasing the heat dissipation area and improving heat dissipation efficiency and effect.

[0023] Preferably, the control device includes an electrically connected PCBA 17 and an inverter. The cooling chip 12 is electrically connected to the PCBA 17. The inverter inverts the current, and the cooling chip 12 is switched between hot and cold by changing the direction of the current.

[0024] Furthermore, the control device also includes a control switch 18 electrically connected to the PCBA 17. The control switch 18 includes a cooling switch and a heating switch. By pressing the cooling switch or the heating switch, the cooling mode or the heating mode can be quickly switched.

[0025] This embodiment also discloses a water-circulating cooling and heating switching air-conditioning garment device, which includes the above-mentioned water-circulating cooling and heating switching device 1.

[0026] Preferably, the device includes a garment body, which includes a water circulation device 2 corresponding to a part of the human body. The water circulation device is connected to the inlet and outlet of the water cooling head 11. In this embodiment, the water cooling head 11 is connected to the water circulation device through the inlet and outlet to achieve reflux. The water circulation hot and cold switching device 1 can be installed on the garment body through a detachable device such as Velcro. It is designed to be lightweight, easy to carry and wear, and the wearer can put it on whenever needed without being restricted by fixed air conditioning equipment.

[0027] Furthermore, the device also includes a submersible pump 21, a first connecting water pipe 22, and a second connecting water pipe 23. The first connecting water pipe 22 and the second connecting water pipe 23 are respectively connected to the inlet and outlet of the water cooling head 11, and the submersible pump 21 is connected to the first connecting water pipe 22. The water circulation device includes an input main water passage 24 and an output main water passage 25. The input main water passage 24 and the output main water passage 25 are respectively connected to the first connecting water pipe 22 and the second connecting water pipe 23. The output main water passage 25 is connected to the input main water passage 24 through several sets of branch water passages 26 to realize the return of cold water or hot water. Under the pumping action of the submersible pump 21, water flows sequentially along the first connecting water pipe 22, the water cooling head 11, the second connecting water pipe 23, the main output water path 25, the branch water path 26, and the main input water path 24 to achieve the return of cold or hot water, thereby realizing continuous cooling or heating cycle.

[0028] Specifically, the branch water path 26 can be configured with multiple diversion paths and circulation loops according to the back and neck of the human body. In this embodiment, the branch water path 26 is configured to divert water from the neck to the left and right sides, and then flow to the back, waist and other parts, so that the cooling or heating effect is balanced and there will be no local overcooling or overheating. In addition, the branch water path 26 diffuses and circulates from the inside to the outside to ensure a balanced and comfortable core sensation.

[0029] The working principle of the water circulation heating and cooling switching device 1 and the air-conditioning garment device in this embodiment is as follows: (1) Working process of cooling mode: When the cooling switch is pressed, the inverter reverses the current and uses the change in current direction to cool the cooling chip 12. The heat sink 13 absorbs the heat from the cooling chip 12. At the same time, the blower mechanism 14 and the exhaust mechanism 15 work to generate a continuous airflow to remove the heat from the heat sink 13 and achieve heat dissipation and cooling. At this time, the cooling chip 12 conducts the cold energy to the water cooling head 11 to cool the water inside it. Under the pumping action of the submersible pump 21, the cooled water flows out from the water cooling head 11 and flows sequentially along the main output water channel 25, the branch water channel 26 and the main input water channel 24, and finally flows back to the water cooling head 11 to achieve adjustable cooling of the back and neck of the human body.

[0030] (2) Working process of heating mode: Pressing the heating switch inverts the current through the inverter, and by changing the direction of the current, the cooling chip 12 heats up. At this time, the cooling chip 12 conducts heat to the water cooling head 11 to heat up the water inside it. Under the pumping action of the submersible pump 21, the heated water flows out from the water cooling head 11 and flows sequentially along the main output water channel 25, the branch water channel 26 and the main input water channel 24, and finally flows back to the water cooling head 11 to achieve adjustable cooling of the back and neck of the human body.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
