Abstract

The invention discloses a heat exchanger which comprises a plurality of parallel heat exchange pipes and an axially-arranged fin perpendicular to the heat exchange pipes. The fin is provided with through holes through which the heat exchange pipes penetrate. The edges of the through holes extend in the axial direction of the heat exchange pipes to be provided with flanges which make tight contact with the outer surfaces of the heat exchange pipes. The invention further provides a refrigerator. According to the scheme, the fin carries out cold transfer with the heat exchange pipes through the flanges, the contact area between the fin and the heat exchange pipes is enlarged, and the cold transfer efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchanger and a refrigerator. Background technique [0002] Due to the high heat exchange efficiency of fin heat exchangers, fin heat exchangers are often used for refrigeration in existing refrigerators. The fin heat exchangers include heat exchange tubes and fins. Holes, where the fins are in contact with the heat exchange tubes by pressing to transfer the cold energy in the pipes to the fins, and then transfer the cold energy to the inside of the refrigerator through the exchange of air, because the fins only have the same cross section as the The heat exchange tubes are in contact, the contact area between the fins and the heat exchange tubes is small, and the cooling transfer efficiency is low. Contents of the invention [0003] The invention proposes a heat exchanger and a refrigerator, aiming at solving the technical problem of low cold transfer efficiency ...
