Description

Technical Field

[0001] This invention belongs to the technical field of wearable high-temperature work cooling equipment, specifically a semiconductor refrigeration water circulation air-conditioning garment. Background Technology

[0002] Currently, most semiconductor-cooled air-conditioning clothing on the market adopts an air-cooled heat exchange structure, relying on air circulation within the interlayer to achieve cooling. This results in a low air heat exchange coefficient, poor heat exchange efficiency, and slow air circulation speed. It can only achieve localized short-term cooling of the human body and cannot evenly cover large areas of the body's core heat dissipation areas such as the chest and back.

[0003] Existing water-cooled clothing generally suffers from the following drawbacks: 1. The cooling unit is fixed to the garment as a single piece, making it impossible to quickly separate and wash the garment separately, resulting in low reuse rate of the cooling unit; 2. The hot and cold ends of the semiconductor cooling chip are simply tightened with screws, leading to gaps at the contact surface after long-term wear and vibration, significantly reducing thermal conductivity, increasing cooling power consumption, and shortening equipment lifespan; 3. The external connector of the cooling unit's water circuit is only compatible with a single garment body, lacking a universal expansion interface, making it incompatible with cooling products such as water-cooled cushions and blankets, thus limiting application scenarios; 4. The water circuit layout lacks a breathable structure, making low-temperature pipes prone to condensation, resulting in stuffy and uncomfortable wear; the cooling unit only supports a single installation method of being built into a sandwich layer, making it unsuitable for high-intensity outdoor work scenarios requiring frequent disassembly of the unit; 5. The heat dissipation shell lacks directional airflow, causing heat accumulation on the hot surface of the cooling chip, further weakening the overall cooling effect. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing air-cooled clothing, such as low heat exchange efficiency, inconvenient disassembly and cleaning of traditional water-cooled clothing, loose bonding of cooling elements, poor scene scalability, poor heat dissipation, and stuffiness caused by condensation when worn.

[0012] Preferably, the water pump has a pumping end and a water output end. The pumping end of the water pump is connected to a water storage box, and the water output end of the water pump is connected to the outlet pipe of the double water pipe connector male via a first water pipe.

A water inlet is opened on the water storage box, and the water storage box is respectively equipped with an inlet pipe and a delivery pipe.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] As shown in the figure, the semiconductor-cooled water-circulating air-conditioned garment of the present invention includes a garment body 1 and a cooling device 12, the cooling device 12 being located on the inner back side of the garment body. The cooling device 12 includes a housing, a water-cooling head assembly disposed within the housing, a water pump 20, a water storage box 19, and a heat dissipation assembly. The garment body 1 includes a front chest region 4, a front chest region 6, and a back region 10. The front chest region 4 has a circulating water channel 3 covering its area, the front chest region 6 has a circulating water channel 5 covering its area, and the back region 10 has a circulating water channel 9 and a circulating water channel 17 covering its area. Each circulating water channel in the front chest region 4, the front chest region 6, and the back region 10 is a multi-bend circulating water channel. The circulating water channels 17, 5, 3, and 9 are sequentially interconnected. Figure 1 , Figure 2 and Figure 11 This is a diagram showing the unfolded form of the vest of the present invention after the ties 18 are untied.

[0036] The refrigeration device 12 is equipped with a double water pipe connector 13. The inlet 15 of the circulating water path 17 and the outlet 16 of the circulating water path 9 are connected by a double water pipe connector 14.

[0037] The garment body 1 has a sandwich structure, consisting of a top layer 1B and a bottom layer 1C. The circulating water channel 3 is a sealed hollow water channel formed by hot pressing the sandwich layer of the chest area 4; the circulating water channel 5 is a sealed hollow water channel formed by hot pressing the sandwich layer of the chest area 6; and the circulating water channels 9 and 17 are sealed hollow water channels formed by hot pressing the sandwich layer of the back section area 10. Figure 1 The gray lines are hot-pressed lines 1A, and the hollow water channel enclosed by hot-pressed lines 1A is the circulating water channel.

[0038] A flexible hose 311 (plastic tube) is inserted into the circulating water channel 31 at the shoulder of the garment, a flexible hose 321 (plastic tube) is inserted into the circulating water channel 32 at the shoulder, a flexible hose 511 (plastic tube) is inserted into the circulating water channel 51 at the shoulder, and a flexible hose 521 (plastic tube) is inserted into the circulating water channel 52 at the shoulder, so that water can flow smoothly through the shoulder area without obstruction. Because the hollow water channel formed by heat pressing is easily compressed after bending in the transition area of ​​the shoulder, the flow channel becomes narrower or even blocked.

[0039] The hot pressing of the circulating water channel can also be replaced by ultrasonic integrated welding, and the garment body interlayer is formed into a sealed hollow water channel by ultrasonic integrated welding.

[0040] The circulating water path can also be made up of independent hoses sewn and fixed inside the garment's interlayer.

Then, the water flows into the water storage box 19 through the water outlet 232 of the water cooling head 23 from the water inlet pipe 192, forming an uninterrupted closed-loop cooling water circulation.

[0045] The housing includes an upper cover 121 and a bottom shell 127. The upper cover 121 has a side vent 124 and an upper vent 125 on its side and top, respectively.
