Embodiment 1

[0028] Example 1, a cooling suit with phase change material, such as figure 1 As shown, the clothing body 1 is included. The clothing body 1 is provided with a phase change material 107. The phase change material 107 can change its phase state within the phase change range, absorb and store a large amount of heat in the form of latent heat, and choose a phase change temperature close to The human body temperature phase change material 107 can effectively absorb the excess heat in the human body without causing a series of negative physiological reactions such as excessive cold exposure of the skin, vasoconstriction, and tissue soreness. The phase change material 107 may be one or more of a porous graphite-based energy storage material, an inorganic salt phase change composite material, a stearic acid and diatomite composite phase change energy storage material.

[0029] Such as figure 2 As shown, the garment body 1 includes an outer heat insulation layer 101 and an inner breathab...

Embodiment 2

[0032] Embodiment 2, a cooling suit with a phase change material, a pressure reducing valve 203 and a first pressure gauge 204 are arranged between the vortex tube 202 and the ventilation layer 104, the pressure reducing valve 203 can effectively adjust the cold air outlet of the vortex tube 202 The first pressure gauge 204 can monitor the pressure of the gas flowing out of the end 212 in real time.

[0033] The other structure of this embodiment is the same as 1.

Embodiment 3

[0034] Embodiment 3, a cooling suit with phase change material, a second pressure gauge 205 is arranged between the vortex tube 202 and the compressed air supply end, and the second pressure gauge 205 can monitor the compressed air supply end flowing through the vortex tube in real time 202 gas pressure.

[0035] The other structure of this embodiment is the same as 1 or 2.

Abstract

The invention discloses a cooling garment with a phase-change material. The garment comprise a garment body, and a phase change material is arranged in the garment body. The garment body comprises anouter heat insulation layer and an inner breathable close-fitting layer. A phase-change material filling layer filled with the phase-change material is arranged between the breathable close-fitting layer and the heat insulation layer, a ventilation layer is arranged between the phase-change material filling layer and the breathable close-fitting layer, the ventilation layer is provided with an airinlet and an air outlet, and the air inlet is connected with a vortex type refrigeration device. According to the garment, high-pressure air can be divided into cold air and hot air when passing through the vortex tube, the cold air is introduced into the garment body through the temperature control valve above the vortex tube to achieve the purpose of cold accumulation, and meanwhile, air in theventilation layer is subjected to forced convection through the speed regulation fan, so that the problems of local supercooling and the like are avoided. The garment is mainly characterized in thata power supply is not mainly used for refrigerating to provide a cold source, and the vortex tube is mainly used, so that the phase-change material in the garment body accumulates cold.

Description

Technical field [0001] The invention relates to the technical field of cooling clothing, in particular to a cooling clothing with phase change materials. Background technique [0002] At present, most of the mining depths of state-owned coal mines in my country have exceeded 800m. Since the increase rate of coal field temperature is generally 2~4℃ / 100m, with the continuous development of mining depth in the mine, the problem of high temperature in the mine has become more and more prominent, and the thermal damage in the mine has become a bottleneck restricting the development of the coal industry. Therefore, it is urgent to cool down the mine. When workers penetrate protective clothing with poor water permeability and work in a high-temperature working environment, the heat produced by the human body is difficult to dissipate and will be stored in the body. In this case, the body temperature will continue to rise. Under the condition of non-infectious pathological fever, the b...
