Condenser and refrigeration device

Abstract

The invention provides a condenser and a refrigeration device. The condenser comprises N collecting pipes and M sets of flat pipes, wherein each set of flat pipes are arranged between the adjacent collecting pipes in a parallel form; the flat pipes are mounted on the collecting pipes; the two ends of the flat pipes are respectively communicated with the adjacent collecting pipes; N is an integer more than or equal to 3; M is an integer more than or equal to 2. Through the technical scheme provided by the invention, on the one hand, the heat exchange area is increased, the heat exchange effect is enhanced, and the radiating property of the condenser is further improved; on the other hand, materials are effectively saved, and the pressure drop of a compressor and the on-way resistance of refrigerant are reduced, so that the overall power consumption is reduced and the charging quantity of the refrigerant 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 paste galvanized steel pipe or Bondi tube inside the side panel of the refrigerator. In the covering method, the contact between the pipe and the side plate is a line contact, and the heat dissipation effect mainly depends on the thermal conductivity of the pipe and the heat dissipation area of ​​the aluminum foil. Because the contact mode between the condenser and the side plate is line contact, the contact area is small, and the thermal conductivity of the steel pipe is small, which leads to poor heat exchange effect of the refrigerator. However, in the prior art, in order to enhance heat exchange, the method us...

[0003] On the other hand, since the refrigerant in the condensation process, from the superheated region to the two-phase region, and then to the subcooled region, its fluid specific volume and flow rate gradually decrease, but the flow section of the ordinary condenser does not change along the process. Although it can meet the requirements of heat dissipation, the material consumption is more, resulting in an increase in the pressure drop of the compressor and an increase in the resistance of the refrigerant along the way.
