Condenser and refrigeration equipment

Abstract

The invention provides a condenser and refrigeration equipment. The condenser comprises N collecting pipes and M groups of condenser pipes, wherein each group of condenser pipes are arranged between adjacent collecting pipes in parallel, and the condenser pipes are mounted on the collecting pipes; the two ends of each condenser pipe are respectively communicated with the corresponding adjacent collecting pipes, N is an integer greater than or equal to 3, and M is an integer greater than or equal to 2. Through the technical scheme, on one hand, the radiating performance of the condenser can be further improved, and on the other hand, the on-way resistance of a refrigerating fluid can be effectively reduced, so that the discharge pressure and power of a compressor are reduced, then the energy consumption of complete machine of the refrigeration equipment is reduced, and the charging amount of the refrigerating fluid is reduced.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a condenser and a refrigeration device. Background technique [0002] In the traditional refrigerator design, there are two kinds of natural convection condensers: one is to hang on the back of the refrigerator; the other is to use aluminum foil to stick galvanized steel pipe or Bondi tube to the inside of the side panel of the refrigerator, no matter what kind of natural convection For convective condensers, the pipeline flow path is a pipeline from the beginning to the end, and the interface of the pipeline does not change. figure 1 It is an ordinary Bondi tube or galvanized steel tube condenser, the outer diameter of the tube is generally 4mm, and the wall thickness is 0.5mm. As the refrigerant goes from the superheated region to the two-phase region and then to the supercooled region during the condensation process, its specific volume and flow rate grad...

AI Technical Summary

Problems solved by technology

As the refrigerant goes from the superheated region to the two-phase region and then to the supercooled region during the condensation process, its specific volume and flow rate gradually decrease, while the flow section of the ordinary condenser does not change along the process, although it can meet the heat dissipation requirements, but It will lead to an increase in the resistance along the process, which will lead to an increase in the discharge pressure and power of the compressor, thereby increasing the energy consumption of the refrigerator
