Description

Technical Field

[0001] The utility model relates to the technical field of plate coolers, in particular to a plate cooler. Background Art

[0002] The plate cooler is a high-efficiency cooler made of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate cooler is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube cooler, the footprint is one-third of the tube cooler, and the heat recovery rate can be as high as 90%. When assembling multiple cooling plates of traditional plate coolers, in order to improve the sealing, more complicated operations are required to pressurize and eliminate gaps between multiple cooling plates, which affects the installation efficiency; when the cooling plates that have been used for a long time need to be disassembled, cleaned and maintained, the disassembly operation is more cumbersome, which affects the disassembly and maintenance efficiency.

[0003] In the plate cooler disclosed in publication number CN209131463U, although multiple continuous S-shaped channels can increase the flow of the fluid in the high-efficiency plate cooler, it has a higher comprehensive flow and heat exchange performance, improves the cooling efficiency of the high-efficiency plate cooler, and under the same heat load requirements, the required heat exchange area is smaller, reducing the investment cost of the enterprise and saving the operating cost of the enterprise.

[0004] However, the plate cooler has the following disadvantages:

[0005] (1) When assembling multiple cooling plates, in order to improve the sealing performance, a relatively complicated operation is required to pressurize the gaps between the multiple cooling plates, which affects the installation efficiency;

[0006] (2) When it is necessary to disassemble, clean and maintain the cooling plate that has been used for a long time, the disassembly operation is relatively cumbersome, which affects the disassembly and maintenance efficiency. Utility Model Content
