Automatic hot fluorine defrosting type unit

Abstract

The invention discloses an automatic hot fluorine defrosting type unit, which relates to the technical field of refrigerators. The automatic hot fluorine defrosting type unit comprises a fixing support, a refrigeration part, a water collecting and conveying part, a heat absorbing part and a heat releasing part which are connected are installed in the fixing support, the refrigeration part is used for refrigeration, and condensate water can be generated in the refrigeration process; the water collecting and conveying part is used for collecting and conveying condensate water generated by the refrigeration part. Heat on the outer side and the inner side of the heat dissipation device is fully absorbed through the multiple heat dissipation fins, meanwhile, due to the shape of the heat dissipation device, the density of the heat dissipation fins in the space on the inner side of the heat dissipation device is relatively high, the cooling speed of the inner side of the heat dissipation device is increased, the temperature of the compressor unit and the temperature of the periphery of the compressor unit are rapidly reduced, and through the structure, the internal cooling effect of the heat dissipation device is stronger than the cooling effect of the outer side of the heat dissipation device, the service life of the compressor is prolonged, and the working efficiency of a refrigeration part is guaranteed.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an automatic hot fluorine flushing frost type unit. Background technique [0002] Because the air cooler can force air supply and improve heat exchange efficiency; it has a water receiving tray, it is convenient to defrost, and can adapt to various working conditions; the cost is relatively cheap, and the initial investment is low; it has become the most commonly used evaporator in refrigeration systems. Although the blade spacing of the air cooler has been adjusted accordingly according to different application conditions, due to the forced air supply, the heat transfer temperature difference is increased, so the surface of the air cooler in the medium and low temperature refrigeration system frosts quickly. In medium-sized cold storage projects, parallel units are mostly used as cooling sources. In parallel refrigeration systems, after the liquid supply solenoid valve of ...

Problems solved by technology

[0002]The air cooler can force air supply and improve heat exchange efficiency; it is equipped with a water tray, it is convenient for defrosting, and can adapt to various working conditions; the cost is relatively cheap , Low initial investment; it has become the most commonly used evaporator in refrigeration systems. Although the distance between the cooling fans has been adjusted accordingly according to different application conditions, the forced air supply increases the heat transfer temperature difference, so medium and The surface of the air cooler in the low-temperature refrigeration system frosts quickly. In large and medium-sized cold storage projects, parallel units are often used as cold sources. In parallel refrigeration systems, after the liquid supply solenoid valve of the air cooler is stopped, because other air coolers are still When working, the compressor needs to continue to run, and the residual refrigerant in the air cooler that has stopped working will continue to evaporate, which further aggravates the frosting on the surface of the air cooler

[0003]Most of the existing automatic hot fluorine flushing frosting units use the compressor to work to make the condenser absorb heat and the evaporator to release heat to defrost. The temperature of the compressor and condenser is high, and the working life of the compressor and condenser working at high temperature for a long time will be reduced. At the same time, the condensed water produced by the existing automatic hot fluorine flushing frosting unit during normal operation has not been effectively treated. Utilization, and it takes a long time to shut down for maintenance, so this application provides an automatic hot fluorine flushing frosting unit to meet the demand
