Refrigerator condensation heat dissipation system and control method thereof

Abstract

The invention discloses a refrigerator condensation heat dissipation system and a control method of the refrigerator condensation heat dissipation system, and relates to the technical field of refrigerators. The refrigerator condensation heat dissipation system comprises a refrigerator body, the bottom of the refrigerator body is divided into a refrigerator refrigeration heat dissipation compartment through a foaming plate, and a display control component, a compressor, a variable-frequency direct-current motor fan and a microchannel condenser are sequentially arranged in the refrigerator refrigeration heat dissipation compartment, an environment temperature sensor is mounted on the display control assembly, and the inlet end and the outlet end of the microchannel condenser are provided with an inlet end temperature sensor and an outlet end temperature sensor correspondingly. An air outlet and an air inlet are formed in a cabin ventilation cover, and a louver air inlet is arranged on asecond side plate, so that the air quantity entering the refrigerator refrigeration heat dissipation compartment from the air inlet and the louver air inlet forms an efficient heat dissipation condensation air channel, and finally flows to the outside from the air outlet, so that efficient heat dissipation of the micro-channel condenser and the compressor is realized, and the air inlet quantity and the air flowing smoothness of the refrigerator refrigeration heat dissipation compartment are improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to a condensation and heat dissipation system of a refrigerator and a control method thereof. Background technique [0002] Because of its excellent thermal performance, large cooling capacity per unit volume and low price, R290 refrigerant is a better environmental protection substitute suitable for use in large household freezers and commercial freezers. At present, the R290 compressor with a large cooling capacity needs to use fans for forced convection heat dissipation to meet the performance of the R290 compressor; [0003] In the field of R290 compressors, the maximum temperature that the winding coil of the compressor motor can withstand and the temperature of the compressor shell have a certain temperature range requirement, and the quality of the condensation cooling system directly affects the overall cooling performance and noise of the freezer; when the compression...
