Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a plate heat exchanger for heating. Background Art

[0002] The plate heat exchanger is a kind of high-efficiency heat exchanger made of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light 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 heat exchanger, and the footprint is one-third of that of the tube heat exchanger. The heat recovery rate can be as high as 90%. The climate in some areas is relatively dry and the water is more alkaline. After a period of use, scale will adhere to the inner wall of the heat exchanger. If it continues to be used, the scale will accumulate more and more, thereby affecting the heat exchange efficiency of the heat exchanger and even causing the heat exchanger to be blocked.

[0003] However, in the prior art, some plate heat exchangers for heating use ultrasonic sources to generate high-frequency vibrations on the liquid for cleaning. However, this cleaning method is costly and cannot reduce the amount of scale generated from the source. At the same time, cavitation also has a certain corrosive effect on the tube wall.
