Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger-separator integrated detachable plate heat exchange device. Background Technology

[0002] A heat exchanger is a device used to exchange heat between two or more fluids. Its basic function is to transfer heat from one fluid to another through heat transfer methods such as conduction, convection and radiation, thereby achieving the purpose of cooling or heating.

[0003] In the existing technology, there are devices that integrate vapor-liquid separators with plate heat exchangers. For example, a U-shaped vapor-liquid separator is fixed to the top of the plate heat exchanger through a "three-point support" structure, thereby reducing the floor space and eliminating the need for additional support.

[0004] However, this integrated welded or rigidly connected structure has a significant drawback: when the gas-liquid separator needs to be cleaned, inspected, or its accessories replaced, the disassembly and maintenance work is very cumbersome because it is firmly connected to the plate heat exchanger as a whole. It often requires the use of large tools or even cutting, resulting in long maintenance cycles, high costs, and affecting the maintainability of the equipment. Therefore, this utility model proposes an integrated detachable plate heat exchanger-separator device to solve the above problems. Utility Model Content
