Description

Technical Field

[0001] The utility model belongs to the field of plate heat exchangers, and particularly relates to a plate heat exchanger. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchange device, consisting of a series of stacked metal plates with a certain corrugated shape. Its working principle is to allow hot and cold fluids to exchange heat through the fluid channels between the plates. Plate heat exchangers have many advantages, such as high heat transfer efficiency, compact structure, small footprint, and light weight. They can achieve efficient heat transfer under small temperature differences and adapt to various working conditions. They are widely used in many fields such as HVAC, chemical industry, food, and energy. However, in actual applications, the problem of limited inlet and outlet pipe lengths of plate heat exchangers often causes many problems for users. First, due to the limited inlet and outlet pipe lengths, when it is necessary to connect to equipment at a distant location, The use of various additional components undoubtedly increases the complexity and cost of the system. The installation and disassembly process of these components is tedious and laborious, requiring a lot of manpower and time, and increasing the difficulty of maintenance and repair. Moreover, since the connection length of these components is inconvenient to adjust, it is difficult to accurately match the actual needs. During the installation process, if the connection length needs to be adjusted, it is often necessary to disassemble and reinstall the components. This process is not only troublesome, but may also cause damage to the components. In summary, the connection problem caused by the limited length of the inlet and outlet pipes of the plate heat exchanger seriously affects its effect and convenience in practical applications, so there is an urgent need to develop a plate heat exchanger to solve this problem.
