Energy-saving type air cooler

Abstract

The invention discloses an energy-saving type air cooler and aims at providing an air cooler which can prevent defrost heat from entering cold environment, ensure the evenness of temperature field of a refrigerator, avoid the influence of the frost thawing on the quality of goods in the refrigerator and meet the storage requirement of the refrigerator. Two ends of an air channel are provided with an air inlet and an air outlet respectively; the air inlet is provided with an air inlet wind baffle for sealing the air inlet after being closed; the air outlet is provided with an air outlet wind baffle for sealing the air outlet after being closed; the inside of the air channel is provided with a heat exchanger; and a draught fan is arranged between the heat exchanger and the air outlet. In the energy-saving type air cooler, the air outlet of the air cooler is provided with the wind baffle which prevents the heat dissipation during the defrosting. The air inlet is provided with the wind baffle; during the defrosting, the wind baffle can avoid the influence of the frost thawing on the quality of the goods in the refrigerator, does not pollute the goods in the refrigerator and does not generate large fluctuation on the temperature of the refrigerator so as to ensure convenient, rapid, safe and reliable frost thawing and meet the storage requirement of the refrigerator.

Description

technical field [0001] The invention relates to a cooling fan. Background technique [0002] For traditional cold storage air coolers, there are many defrosts in defrosting. First of all, in terms of food safety, when traditional cold storage evaporators use hot gas defrosting or electric defrosting, since the heat exchanger is not isolated from the cold space during defrosting, the melting of frost will not only make the items damp, but also Items stick together into blocks, and defrosting will have a certain impact on the temperature field in the storage room, resulting in large temperature fluctuations in the room, and the rise in storage temperature will damage the storage quality of food. Therefore, it generally takes a long time for the user to defrost once, resulting in a reduction in the cooling efficiency of the refrigeration system. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provi...

Problems solved by technology

First of all, in terms of food safety, when traditional cold storage evaporators use hot gas defrosting or electric defrosting, since the heat exchanger is not isolated from the cold space during defrosting, the melting of frost will not only make the items damp, but also Items stick together into blocks, and defrosting will have a certain impact on the temperature field in the storage room, resulting in large temperature fluctuations in the room, and the recovery of storage temperature will damage the storage quality of food

Therefore, it usually takes a long time for the user to defrost once, resulting in a decrease in the cooling efficiency of the refrigeration system.
