Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, and in particular to an anti-clogging structure for plate heat exchangers. Background Technology

[0002] Plate heat exchangers are a common type of heat exchange equipment, widely used in refrigeration, air conditioning, chemical, food processing and energy fields. Plate heat exchangers separate two fluids through multiple parallel metal plates, and heat exchange occurs as the fluids flow between the plates. Compared with traditional shell-side heat exchangers, plate heat exchangers have higher heat exchange efficiency and smaller volume.

[0003] In existing plate heat exchangers, hot and cold water are injected separately into the space between multiple metal plates through the inlet, allowing the hot and cold water to flow in different channels within the heat exchanger. The hot fluid releases heat, and the cold fluid absorbs heat. During the water injection process, because the liquid is not filtered, impurities in the liquid can easily flow into the plate heat exchanger through the inlet and accumulate between the metal plates, affecting the liquid flow within the heat exchanger. In view of this, this solution proposes an anti-clogging structure for plate heat exchangers to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging structure for plate heat exchangers to solve the problems mentioned in the background art.
