Efficient defrosting device of air cooler

Abstract

The invention relates to an efficient defrosting device of an air cooler. The device comprises an air outlet side louver, an air outlet side louver connecting rod, an air outlet side connecting rod controller, an air return side louver, an air return side louver connecting rod and an air return side louver connecting rod controller. When the air cooler is in a refrigerating working condition, theair outlet side louver and an air inlet side louver are opened at the same time, and a cold air flow performs a refrigerating cycle on the air inlet side and the air outlet side. When the air cooler is in a defrosting working condition, the air outlet side louver and the air inlet side louver are closed at the same time to fence fins of the air cooler fully. At the moment, hot air for defrosting is limited between air outlet side louver and the air return side louver to flow, so that hot air for defrosting is prevented from overflowing. Thus, the defrosting efficiency of the air cooler is improved and temperature rise in a refrigerator is inhibited. Moreover, problems of frosting, condensation, water dropping and the like of a top surface of the refrigerator are also avoided. Meanwhile, the air outlet side louver in the closed state can be taken as a baffle plate to separate a motor of the air cooler from the fins of the air cooler so as to prevent defrosting water from flowing into the motor, so that the working environment of the motor is protected and the service life of the air cooler is prolonged.

Description

technical field [0001] The patent of the present invention relates to the thermal defrosting technology of the refrigeration system, specifically a high-efficiency air cooler defrosting device. Background technique [0002] The air cooler is an evaporator commonly used in the refrigeration system of the cold storage. Under low temperature conditions, the air cooler usually has frosting. If the frost layer is too thick, its heat transfer performance will be greatly reduced and the cooling effect of the air cooler will be deteriorated. This requires timely defrosting treatment. In the two main methods of air cooler defrosting (electric heating defrosting and hot fluorine defrosting), there will always be a phenomenon that the hot air used for defrosting overflows from the air outlet side and the return air side of the air cooler. The overflowing hot air not only reduces the defrosting efficiency, but also causes the temperature inside the cold storage to rise, resulting in fr...

AI Technical Summary

Problems solved by technology

The overflowing hot air not only reduces the defrosting efficiency, but also causes the temperature inside the cold storage to rise, resulting in frosting, condensation, and dripping on the ceiling of the cold storage.
