[0002] A corrosion-resistant plate heat exchanger refers to a new type of high-efficiency heat exchanger, which is composed of a series of corrosion-resistant metal sheets with a certain corrugated shape stacked together. Thin rectangular channels are formed between these plates, and heat exchange is carried out through half plates. Compared with conventional shell-and-tube heat exchangers, the heat transfer coefficient of plate heat exchangers is much higher, and there is a trend to replace shell-and-tube heat exchangers within the applicable range. A ship refers to the general term for various vessels, which is an artificial means of transportation mainly operating in geographical waters. A corrosion-resistant plate heat exchanger is required on ships. During the use of the corrosion-resistant plate heat exchanger for ships, a noise reduction structure is needed to improve the use effect of the corrosion-resistant plate heat exchanger for ships.
