Embodiment Construction

[0022] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0023] see figure 1 , 2 , the flat tubes 1 are bent into serpentine tubes, and heat sinks 2 are arranged between adjacent serpentine flat tubes. The upper and lower ends of the flat tubes 1 are respectively connected with a heat sink 2, and the side plates 8 are connected to the heat sink 2 connection to protect the heat sink. One end of the serpentine flat tube 1 is connected with the inlet tube assembly 3 , and the other end of the serpentine flat tube 1 is connected with the outlet tube assembly 4 .

[0024] Such as image 3 As shown, the inlet pipe assembly 3 and the outlet pipe assembly 4 are formed by copper-aluminum resistance welding of the copper pipe 6 and the special joint 5, and a radiation cross-linked heat shrinkable sleeve 7 is arranged at the welding place.

[0025] see Figure 4 ,...

Abstract

The invention relates to the technical field of refrigerating components, in particular to a coiled parallel flow condenser for a refrigerator, which is bent into a multi-layer coiled shape by using aluminum flat pipe at a certain radius of arc. The condenser comprises a flat pipe, fins, an inlet pipe assembly and an outlet pipe assembly, and is characterized in that the flat pipe in a coiled shape is formed by multiple bending arcs and straight lines; radiation sheets are equipped between adjacent coiled flat pipes; radiation sheets on outer side on both ends are equipped with side plates; inlet and outlet ends of the flat pipe are connected with the inlet pipe assembly and the outlet pipe assembly, respectively; the inside of the flat pipe is equipped with multiple micro-passages through which refrigerant passes. The condenser is compact in structure, high in heat exchange performance in unit volume, small in flow resistance, less in material consumption, less in cold medium filling quantity.

Description

technical field [0001] The invention relates to the technical field of refrigeration components, in particular to a serpentine parallel-flow condenser for refrigerators that uses aluminum flat tubes and bends them into a multi-layer serpentine shape according to a certain arc radius. Background technique [0002] The condenser is an important part of heat conversion in refrigerators or refrigeration equipment, and its structure directly affects the cooling effect. Parallel flow condensers have been widely used in automotive air conditioners, commercial air conditioners and other products. The existing refrigerator condensers, It is mainly made of circular metal tubes, and steel wires for increasing heat transfer are welded on the metal tubes, and the whole part needs to be treated with electrophoresis and antirust. In order to achieve the cooling effect of refrigerators, manufacturers need to increase the condensation of refrigerators. The heat exchange area of ​​the device ...
