Condenser assembly for refrigerator, refrigerator refrigeration system and refrigerator

Abstract

The invention discloses a condenser assembly for a refrigerator, a refrigerator refrigeration system and the refrigerator, and belongs to the technical field of refrigerators. The condenser assembly for the refrigerator comprises a water receiving disc and a parallel flow condenser arranged on the water receiving disc. The parallel flow condenser comprises a first collecting main, a second collecting main and a plurality of flat tubes arranged between the first collecting main and the second collecting main in parallel. A partition plate is arranged in at least the first collecting main, a plurality of micro-channels are formed in each flat tube, and fins are arranged between the flat tubes. The condenser assembly for the refrigerator is high in heat exchange efficiency, the filling amount of refrigerants is small, occupied space is small, and the structure is more compact. Due to the fact that the refrigerator refrigeration system and the refrigerator comprise the condenser assembly for the refrigerator, the refrigerator refrigeration system and the refrigerator are smaller in size, more compact in structure and more convenient to mount.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a condenser assembly for a refrigerator, a refrigerator refrigeration system and a refrigerator. Background technique [0002] At present, the condensers in the condenser components used in air-cooled refrigerators are mostly rotary-fin and wire-tube condensers. Usually, these two condensers are placed in the mechanical room, occupy a large volume, and have average heat transfer efficiency. Costs cannot be effectively controlled. [0003] In order to improve the heat transfer performance, the traditional condenser mainly starts from the following two aspects: 1) Improve or adjust its internal structure, size, and number of tube rows; 2) Change the size of the air-side fin form and structural parameters. Although these measures have improved the heat transfer performance to a certain extent, they are only changed within a limited range. In particular, the effective way to i...

Problems solved by technology

Although these measures have improved the heat transfer performance to a certain extent, they are only changed within a limited range. In particular, the effective way to improve the heat transfer performance of finned condensers is to increase the heat transfer area, which undoubtedly needs to be increased. The volume of the condenser will occupy the effective volume of the refrigerator compartment accordingly.

[0004] On the other hand, in the traditional rotary-fin, wire-tube, and tube-sheet condensers, the channels through which the refrigerant flows are mostly single-flow, single-channel, and circular cross-section. The single-flow single-channel structure increases the The resistance increases the filling amount of the refrigerant; the circular cross-section structure reduces the heat transfer effect on the refrigerant side; overall, it is not good for the heat dissipation capacity and cooling performance of the entire box, and causes waste of pipes and auxiliary materials

[0005] On the other hand, the current condenser components used in air-cooled refrigerators are not compact in structure, occupy a large volume, and are not easy to install.
