Description

Technical Field

[0002] The corrosion-resistant and crack-resistant heat exchange device is a device that can resist chlorine corrosion and extend its service life. The heat exchange device is a device that transfers heat from hot fluid to cold fluid. Heat exchange equipment is widely used in oil refining, chemical industry, light industry, pharmaceutical industry, machinery, food processing, power and atomic energy industry sectors.

[0003] For example, the Chinese utility model patent (CN 211147425 U) provides a heat exchange device. The heat exchange device is used to exchange heat with a heat exchange part. The heat exchange device includes: a heat-conducting structure, the heat-conducting structure has a mounting hole, and a flared portion is provided at the orifice of the mounting hole. The heat-conducting structure contacts the heat exchange part and exchanges heat with it; a heat exchange pipe, the heat exchange pipe is inserted into the mounting hole, and the heat exchange pipe is used to circulate a heat exchange medium. The heat exchange medium circulates in the heat exchange pipe and / or the mounting hole to exchange heat with the heat-conducting structure. The utility model effectively solves the problem that the heat exchange device in the prior art is prone to pipe cutting, which affects the normal use of the heat exchange device.

[0004] However, in the above patent, the temperature of the coolant will rise when cooling, generating steam, which is difficult to dissipate in a closed space, resulting in a decrease in the cooling effect of the coolant and the inability to reuse the steam. When new coolant is added, cracking will occur due to the large temperature difference. The coolant condensed by the steam can be added to the new coolant to neutralize the temperature. When there is a problem with the heat exchange tube or impurities in the liquid inside need to be cleaned, the equipment cannot be disassembled quickly. The disassembly steps are relatively cumbersome and take a lot of time. Therefore, a corrosion-resistant and crack-resistant heat exchange device is required. Utility Model Content
