The present invention is based on the cardinal principle of the Wearable air-ventilating garments of bionical honeycomb:
Mini-refrigerator system mainly comprises micro-compressor, condenser, throttling arrangement, evaporimeter, control element etc., powers to whole mini-refrigerator system by Li-ion batteries piles.Directly enter condenser from micro-compressor high temperature and high pressure gaseous refrigerant out, heat outwardly distributes, condensation of refrigerant becomes highly pressurised liquid, then flow through throttling arrangement, become the gas-liquid mixture of low-temp low-pressure, then flow in evaporimeter, absorb the heat that refrigerating medium water distributes, be evaporated to low temperature low pressure gas, under the suction of compressor, enter compressor, restart new circulation.Refrigerating medium water is transported in plate type heat exchanger and carries out exchange heat by water pump from small-sized water storage box, and the temperature of water reduces, and then enters the honeycomb pipeline in clothes, and after absorbing the heat of human body, temperature raises, and returns in small-sized water storage box, iterative cycles like this.
Control system can regulate compressor rotary speed according to the change of the temperature of the microenvironment in clothes, and change refrigerant flow, make the temperature of microenvironment in clothes remain near design temperature, error is no more than 1.5 DEG C.Thus provide comfortable moist heat for people.
The present invention dresses the air-ventilating garments that assembly can make the patterns such as vest, long sleeve blouse, trousers according to demand.
The critical component of mini-refrigerator system of the present invention is micro-compressor, and micro-compressor adopts Minitype refrigeration compressor, the diameter 54mm of this micro-compressor, within high 69.3mm, weight is not more than 670g, adopts powered by direct current, voltage 12V or 24V, cold-producing medium is R134a; Compressor rotary speed scope is 1800 ~ 6500r/min, can provide the cold of about 300W.
The fin of parallel-flow heat exchanger of the present invention adopts serrated fin, greatly can improve the coefficient of heat transfer.Be equipped with a small-sized fans simultaneously, add the disturbance of strong convection body, obtain the larger coefficient of heat transfer, make fluid have larger degree of supercooling, improve cooling system amount.The manufactured materials of described parallel-flow heat exchanger adopts aluminium alloy, alleviates himself weight.
Throttling arrangement of the present invention adopts capillary, and the caliber of capillary is about 0.67mm, more much smaller than the caliber of evaporimeter.The advantage of capillary is that structure is simple, and movement-less part is cheap; Do not need installing reservoir liquid reservoir during use, refrigerant charge is few, and this is to the gross weight of mitigation system, improves portability helpful; And after compressor shuts down, the pressure in condenser and evaporimeter can reach balance quickly automatically, alleviates the startup load of motor.
The evaporimeter of inventive refrigeration system adopts plate type heat exchanger.Channel width inside plate type heat exchanger and flat, makes described plate type heat exchanger thickness very little, conveniently arranges.Cold-producing medium and refrigerating medium heat exchange in described plate type heat exchanger.
