Embodiment Construction
[0037] The invention provides a process method for diffusion welding of a core body of a stainless steel heat exchanger. Through the process method combined with self-made welding tooling, the quality of welded joints can be well improved, welding defects can be reduced, and the rate of finished products can be increased. At the same time, the invention also has a unique design for the structure of the heat exchanger core. The heat exchanger prepared by using the heat exchanger core has high heat exchange efficiency and compactness, can serve under high temperature and high pressure, and is suitable for special occasions to use.
[0038] Before explaining the diffusion welding process, it is necessary to introduce the structure of the heat exchanger core and the self-made welding tool in detail.
[0039] Such as Figure 1-4 As shown, a compact and high-efficiency heat exchanger core includes an upper metal cover plate 1 , a lower metal cover plate 2 and several intermediate m...
