Five, the specific embodiment
This invention is by being core with the semiconductor refrigerating, realizes goal of the invention in conjunction with the compound-refrigerating method of vapor compression refrigeration, as shown in Figure 1, it is by filter 10, air dryer 11, gas-liquid heat-exchange 12, water tank 1, one-stage steam compressing refrigeration system 6, water pump 7, rectifier power source 13, semiconductor cooler 14, insulating tube 21, nozzle 17 is formed.Nozzle 17 connects and is installed in the position that can implement cooling to the processing district by insulating tube 21 and semiconductor cooler 14.
One-stage steam compressing refrigeration system 6 mainly comprises compressor 2, condenser 3, and expansion valve 4, parts such as evaporimeter 5, wherein evaporimeter 5 places water tank 1, and it mainly plays the water in the cooling water tank 1 and makes it keep the effect of steady temperature.
The embodiment of 1 pair of this invention is made a detailed description with reference to the accompanying drawings:
One, one of cooling circuit: during 6 work of one-stage steam compressing refrigeration system, refrigerant gas is constantly by after the compressor 2 suction compressions, liquefaction in condenser 3, after expansion valve 4 throttling step-downs, enter evaporimeter 5, water in the evaporation heat absorption cooling water tank 1, become gas again and get back to compressor 2, thereby finish the closed cycle of refrigeration working medium.Introduced temperature controller in one-stage steam compressing refrigeration system 6, the temperature-sensing element of temperature controller places water tank 1, is used to measure water temperature, and when water temperature reached the temperature of setting, it is out of service that temperature controller is just controlled compressor 2; In case when water temperature was higher than design temperature, temperature controller just made compressor 2 start, and reduces water temperature.In water tank 1, set up a fluid space that temperature is low and stable like this, thereby realized semiconductor thermoelectric module 18 hot junctions are stablized and heat radiation effectively.
Two, two of cooling circuit: water pump 7 constantly is transported to gas-liquid heat-exchange 12 with the cold water of temperature constant in the water tank 1, in gas-liquid heat-exchange 12 after cold water and the compressed air heat exchange, enter the radiator 19 in the semiconductor cooler 14, strengthen semiconductor thermoelectric module 18 hot-side heat dissipations, and then improve semiconductor refrigerating efficient.
