Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile heat exchanger, specifically relates to a combined heat exchanger side plate. BACKGROUND

[0002] The heat exchanger used in the vehicle, its typical structure is usually to configure multiple flat tubes and fins in the form of alternating layering, thereby constructing a core for heat exchange. The end of the flat tube is connected with the header, ensuring that the fluid can flow smoothly in the system. In order to enhance the stability of the overall structure, the side plate is arranged on the outside of the core as a reinforcing member. These components are combined together through precise brazing welding technology, forming a solid and efficient heat exchanger.

[0003] However, the commonly used side plate at present is mostly made of aluminum alloy sheet through simple stamping process, and this processing technology is convenient, but in some special cases, in order to meet the specific sealing or shock absorption demand, it is necessary to paste foam on the vertical surface of the side plate. In order to realize this function, the side plate needs to be designed into a L-shaped structure with flanging. However, this design brings new problems in the assembly process: the L-shaped side plate cannot be accurately positioned on the assembly machine due to its special shape, which brings challenges to the assembly work.

[0004] In addition, in the brazing process, the fixation of the clamp is also a big problem. Because the L-shaped side plate is protruding larger, after the core assembly is completed, the clamp is difficult to find a suitable fixing position, which not only affects the stability and efficiency of the brazing process, but also may adversely affect the overall quality of the heat exchanger.

[0005] More importantly, the L-shaped side plate is easily affected by thermal stress in the brazing process due to its large size and special shape, thereby affecting the effect of the brazing process. At the same time, the structure of the L-shaped side plate is relatively weak, which is prone to deformation and scratches during engineering or transportation, which undoubtedly increases the product rejection rate and maintenance cost. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a combined heat exchanger side plate, in the assembly process, the clamp can be easily and accurately positioned, which greatly improves the installation accuracy of the assembly machine and significantly improves the brazing yield.

[0013] In one embodiment, a clamping groove is formed between the first support, the L-shaped plate and the second support, and the opening distance of the clamping groove matches the thickness of the heat exchanger core.

[0014] In one embodiment, the opening distance of the clamping groove is the same as the width of the side plate.

[0015] In one embodiment, the first support and the second support are each provided with a mounting boss on the outer surface, and the fixing member passes through the through hole of the mounting boss.

[0016] In one embodiment, the through hole of the mounting boss corresponds to the upper position of the fin of the heat exchanger core.

[0020] The above technical scheme of the utility model has the advantages compared with the prior art:

[0021] 1. Since the fixing support is arranged, the side plate does not need to be turned into an L-shaped structure, so the clamp becomes more convenient and fast when positioning, thereby ensuring the installation precision of the assembled machine before the heat exchanger is welded.

[0022] 2. During welding, since the side plate of the L-shaped structure is not involved, the yield of brazing is greatly improved.
