Chilled water heat exchanger is a kind of high efficiency heat exchanger which is composed of a certain number of corrugated metal plates.The plate heat exchanger transfers heat through the phe plates. The heat transfer forms of the plate heat exchangers are liquid heat transfer and liquid gasification heat transfer. It has the characteristics of high heat exchange rate, low heat loss, light structure, small size, convenient cleaning, multi-purpose and long life. The plate heat exchanger is used in various industries because of its compact structure, convenient cleaning, high heat exchange efficiency and higher cost and higher heat transfer efficiency compared with other heat exchangers. It’s main heat exchange equipment used in the process.For example:The chemical industry manufactures titanium oxide, alcohol fermentation, synthetic ammonia, resin synthesis, rubber production, cooling of phosphoric acid, cooling of formalin, alkali carbon industry and electrolysis of alkali.
