Problems solved by technology
The heat dissipation device of the existing parallel flow condenser is to weld the flat tubes one by one between the two collecting tubes, and the cooling fins generally adopt the curved cooling fins installed between the two flat tubes. This installation method is more troublesome, The heat dissipation effect is not good enough; and the existing condensers generally only have a condensation area, and a few have a supercooling area, but the heat transfer efficiency is low

The invention relates to automobile air conditioner condensers, in particular to a parallel flow condenser of an automobile air conditioner. The parallel flow condenser of the automobile air conditioner comprises a core body, a left flow collecting tube and a right flow collecting tube, and partition plates are mounted in the left flow collecting tube and the right flow collecting tube. The core body is composed of three divided areas which refer to a divided cooling area, a condensing area and an overcooling area from top to bottom. The left flow collecting tube and the right flow collecting tube are correspondingly composed of the divided cooling sections, the condensing sections and the overcooling sections from up to bottom. Each divided area comprises at least one set of porous flat tube cooling device, each set of cooling device comprises a porous flat tube and a plurality of cooling fins which are obliquely arranged on the porous flat tube at intervals in a sleeved mode. According to the parallel flow condenser of the automobile air conditioner, the cooling devices of the core body are mounted in a grouping mode, mounting is simple, time is saved, and mounting efficiency is improved. According to the parallel flow condenser of the automobile air conditioner, gas and liquid separation is conducted on coolants under the action of gravity, the two phases of the coolants are cooled primarily, and the cooling effect is improved. The two phases of the coolants are collected in a liquid storage dryer after primary cooling, then the coolants enter the overcooling area through an overcooling tube to be cooled again, and the cooling effect and the heat transfer efficiency are further improved.
Description
technical field [0001] The invention relates to a condenser for an automobile air conditioner, specifically a parallel flow condenser for an automobile air conditioner Background technique [0002] The structure of the automobile air conditioner condenser is a separate heat exchange core, and the refrigerant enters the condenser to exchange heat and then flows into the evaporator for refrigeration. At present, parallel flow condensers generally include a condenser core body and left and right headers arranged on both sides of the core body. Partition plates are installed in the left and right headers, and the partition plates separate the left and right current collectors. The tube is divided into several sections that are isolated from each other. Each section of the left and right headers and the core form a flow channel for the refrigerant to flow, so that the refrigerant continues to circulate between the left and right headers, and the heat of the refrigerant is taken a...
