Fin falling prevention type parallel flow condenser

Abstract

The invention relates to a fin falling prevention type parallel flow condenser, which comprises a plurality of flat pipes, wherein the flat pipes are communicated with a liquid inlet pipe and a liquid outlet pipe, a fin is arranged between the adjacent flat pipes, and the end surface, attaching with each flat pipe, of each fin is provided with bosses which are in limiting matching with an upper edge and a lower edge of the cross section of each flat pipe, or the end surface, attaching with each fin, of each flat pipe is provided with bosses which are in limiting matching with an upper edge and a lower edge of the cross section of each fin. Each flat pipe or each fin is limited by the bosses on the upper and lower edges of the cross section of each fin or each flat pipe, so the fin falling prevention function is realized during installation and use. The condenser has the advantages that the structure is simple, the manufacturing is convenient and rapid, the cost is low, the pressing and positioning are accurate, the matching of the fins and the flat pipes is stable and reliable, the liquid conveying and heat exchange are uniform, and the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to a condenser, in particular to a parallel flow condenser whose fins do not fall off. Background technique [0002] Parallel-flow condensers are mainly used in the automotive air-conditioning industry. The refrigerant flows in the horizontal direction, and the temperature and pressure are lowered during the flow to achieve the cooling effect. Most of the existing parallel flow condensers are composed of flat tubes and fins at intervals. The peaks and troughs of the fins are respectively attached to the sides of the flat tubes. Connection, there is offset during the welding process, and the brazing is easy to fall off during use, causing the fins to fall off. Its manufacturing, use, and maintenance costs are high, and it has a great impact on the heat exchange efficiency of flat tubes and fins. Condenser The heat transfer efficiency is greatly reduced. [0003] The existing patent application number is 201010298067.X, which disc...
