Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0025] Such as figure 1 As shown, it is a structural schematic diagram of a multi-channel heat exchanger with an integral brazing structure without a head in this embodiment. The hot I-way inlet and outlet joint 1, the cold-way inlet and outlet joint 2, the heat II-way inlet and outlet joint 3 and the core body 4 are assembled to form a heat exchanger. In the exchanger, the head structure of the traditional liquid accumulation function is canceled, and the liquid accumulation function is designed inside the core body 4 .

[0026] Such as figure 2 , image 3 As shown, the outermost layer of the core body 4 is a cover plate 10, and the interior is composed of cold circuit fins 5, cold circuit seals 6, thermal circuit fins 7, thermal circuit seals 8, and partitions 9. The assembly structure of each layer is, from bottom to top, cold circuit fins 5 , cold cir...

Abstract

The invention belongs to the technical field of heat exchanger structure design, and relates to a multi-channel heat exchanger without a sealing head integral brazing structure. The multi-channel heatexchanger without the sealing head integral brazing structure is composed of a first heat path inlet and outlet joints (1), cold path inlet and outlet joints (2), a second heat path inlet and outletjoints (3) and a core body (4). The outermost layer of the core body (4) is a cover plate (10), the internal part is assembled by cold path fins (5), cold path sealing strips (6) and hot path fins (7), hot path sealing strips (8) and separation plates (9) in a laminating mode, and the assembly structure of each layer sequentially comprises the cold path fins (5), the cold path seals (6), one separation plate (9), the hot path fins (7), the hot path sealing strips (8), another separation plate (9) from bottom to top. According to the multi-channel heat exchanger, the end socket structure with the liquid accumulation function in a traditional heat exchanger is omitted, and the core body (4) is provided with the liquid accumulation function, so that the argon arc welding process is reduced, the possibility of brazing cracking caused by high-temperature argon arc welding is avoided, and the yield of the heat exchanger is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchanger structure design, in particular to a multi-channel heat exchanger with an integral brazing structure without a head. Background technique [0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet specified requirements. The traditional heat exchanger is mainly composed of a fluid joint, a head (cover), and a core. After the core is brazed, it is welded together with the head (cover) and the fluid joint by argon arc. The disadvantage of the above-mentioned heat exchanger is mainly that high-temperature argon arc welding is likely to cause cracking of the brazing seam of the core body, resulting in low product yield. Contents of the invention [0003] The object of the present invention is to provide a multi-channel heat exchanger with an integral brazing structure without a head to solve the technical problem that high temperature argon arc weldi...
