Problems solved by technology

However, for the structure in which the maximum length of the flat tube 03 used in the passenger car air-conditioning microchannel heat exchanger can reach 2 meters, if it is only fixed by the bracket 02 of the header 01, not only is its strength and reliability difficult to guarantee, but also the Very high requirements for installation
The method of fixing only by the bracket 02 of the header 01 is likely to cause damage to the passenger car air conditioner under harsh and bumpy road conditions
Therefore, the deficiencies of the existing passenger car air-conditioning microchannel heat exchanger include: (1) the length of the flat tube 03 is generally longer, and there is no fixed point in the length direction of the side plate 04, and only the bracket 02 of the header pipe 01 in the width direction is used for fixing , its strength and reliability are poor
(2) Due to the structural characteristics of the side plate 04 of the micro-channel heat exchanger, it is difficult to increase the fixing point of the micro-channel heat exchanger by simply setting mounting holes directly on the side plate 04

Abstract

The invention discloses a microchannel heat exchanger for an air conditioner of a passenger car. The microchannel heat exchanger for the air conditioner of the passenger car comprises collecting pipes, an installation support, flat pipes and edge plates, wherein a fixing device is arranged on the edge plates, the fixing device is a rectangular box, one side of the rectangular box is open, the rectangular box comprises a bottom surface, an upper installation surface, lower installation surface, a left supporting edge plate and a right supporting edge plate, installation holes are formed in the middle of the upper installation surface and in the middle of the lower installation surface, and clamping grooves are formed in the upper end and lower end of the left supporting edge plate and the upper end and the lower end of the right supporting edge plate; edge plate installation holes are formed in the upper surface and the lower surface of each edge plate at intervals, and the edge plate installation holes and the installation holes are identical and are all round or oval; the upper surface and the lower surface of each edge plate are inserted into the corresponding upper clamping groove and the corresponding lower clamping groove of the fixing device, the installation holes in the upper surfaces and the lower surfaces of the edge plates are made to be in butt joint with the installation holes in the upper installation surface and the lower installation surfaces of the fixing device, and then fixation is achieved through bolts and nuts. According to the microchannel heat exchanger for the air conditioner of the passenger car, fixing points are arranged on the edge plates of the heat exchanger, fixation in the width direction of a collecting pipe support and fixation in the length direction of the edge plates of the microchannel heat exchanger are achieved, and the strength and the reliability of the microchannel heat exchanger for the air conditioner of the passenger car can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of automobile air conditioners, in particular to a microchannel heat exchanger for passenger car air conditioners. The passenger car air conditioners include automobile air conditioners suitable for medium and large passenger cars of 8 to 14 meters in length. Background technique [0002] Microchannel heat exchanger is a major component of passenger car air conditioning. At present, most microchannel heat exchangers are fixed by welding the mounting bracket 02 at the two headers 01 (such as figure 1 shown). Such an installation method is possible for the microchannel heat exchanger whose flat tube 03 is not long. However, for the structure in which the maximum length of the flat tube 03 used in the passenger car air-conditioning microchannel heat exchanger can reach 2 meters, if it is only fixed by the bracket 02 of the header 01, not only is its strength and reliability difficult...
