Circulation, which leads to, is provided with blower fan, evaporator of refrigerator, cooler in the air channel area connect, air channel area, cooler passes through two-way pipeline
The liquid reserve tank for holding cooling fluid is connected with, is wherein provided with to be provided with liquid pump, the second road pipeline on first via pipeline and changes
Hot device.
As a preferred embodiment, cooler is using gilled radiator, plate fin type radiator or tubular type radiating
Any one in device.
As a preferred embodiment, being provided with valve on first via pipeline.
As a preferred embodiment, being provided with safety valve on liquid reserve tank.
As a preferred embodiment, the condenser common fan of heat exchanger and refrigeration machine.
As a preferred embodiment, the aperture of valve can be continuously adjusted.
Employ after above-mentioned technical proposal, the beneficial effects of the utility model are：When spin manifold temperature be less than environment temperature, according to
Refrigerating capacity is provided by refrigeration machine；When spin manifold temperature is higher than environment temperature, can jointly or respectively it be provided by refrigeration machine, cooler
Refrigerating capacity；When providing refrigerating capacity by cooler, cooling fluid is flowed successively through cooler, radiator, liquid storage by fluid pump operation
Case, valve, Returning fluid pump formation are circulated, and heat is distributed into environment, now fan operation；When spin manifold temperature is higher than cold
But during fluid boiling point, the fluid flowed out from cooler may be vaporized, volumetric expansion, pressure rise.Pressure is higher than safety valve
When discharging pressure, the fluid of vaporization discharges from safety valve；The high-low temperature test chamber of this fluid supplement heat rejecter improves cooling rate
And efficiency, and device structure is simplified, reduce cost.
