Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger which is easy to clean. Background Art

[0002] The plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of stacked metal sheets with a certain corrugated shape. It can be used for refrigerant-refrigeration liquid heat exchange and water-water heat exchange. The plate heat exchanger has a higher heat exchange efficiency, so the heat exchanger is more compact and lighter. It is widely used in air conditioners for new energy vehicles and battery and motor cooling subsystems. It can also be used in the chemical industry. The basic principle of the plate heat exchanger is to form mutually spaced flow channels between multiple heat exchange plates, and the two heat exchange media exchange heat through the heat exchange plates in the alternate flow channels.

[0003] At present, the heat exchange plates of plate heat exchangers become dirty after long-term use and need to be cleaned. When cleaning the heat exchange plates of existing plate heat exchangers, each heat exchange plate needs to be removed from the plate heat exchanger for flushing or ultrasonic cleaning. However, the movable splints and heat dissipation plates in the current plate heat exchangers usually have T-shaped grooves on the top, and the T-shaped grooves are inserted into the channel steel for movement and fixed placement. Therefore, it is more troublesome to disassemble and the heat dissipation plates are easily deformed. At the same time, the existing plate heat exchangers usually use a triangular structure support frame for stable support, which is prone to tilting and shaking during the disassembly process, and it is difficult to maintain good stability when the heat dissipation plates are disassembled.
