The plate heat exchanger has developed a glue-free gasket (LOG-IN system). The high-quality gasket is placed in the gasket groove. The gasket is fixed by a pressed lock. It has high pressure resistance and can be replaced quickly and easily. ; For the shell-and-tube heat exchanger, it is almost impossible to increase the area of ​​the original heat exchanger when the processing capacity needs to be increased. The plate heat exchanger can meet the change of process conditions, and the plates increase and decrease accordingly, which eliminates the requirement of expensive reinvestment; in the plate heat exchanger, the small liquid volume is the reason for the light weight of the equipment.

At the same time, it can drive and stop faster than conventional heat exchangers; due to its compact structure and high heat transfer efficiency, for the same heat load, the heat transfer area required by the plate heat exchanger is only that of the shell-and-tube heat exchanger. About 1/3; In the cooling system in the metallurgical process, due to the crystallization of salt in the well water and the deposition of particles such as soil and sand, the growth of organic matter in the seawater is prone to fouling. The fluid flowing between the plates is in a highly turbulent flow, which keeps the solids suspended and makes the rate of fouling formation much smaller than in the shell and tube type.

Plate heat exchangers began to be used in the food industry. Due to the superiority of titanium performance, it is favored by many industries, and many different products are used in many places. At present, the titanium plate heat exchanger has been widely used in petroleum, chemical, electric power, metallurgy, machinery, energy and other industrial fields, and has become a very competitive variety in the heat exchanger family.

Our country began to produce plate heat exchangers in the 1960s. So far, titanium plate heat exchangers have been widely used in many fields in my country. Titanium and titanium alloys are a new kind of corrosion-resistant metal materials. The heat exchanger made of titanium has good corrosion resistance, high heat transfer efficiency, smooth surface without scaling layer, small specific gravity, high strength, small equipment volume and quality, etc. Features, widely used in aviation, space development, ocean engineering, petroleum, chemical industry, metallurgy, electronics, medicine and health, food processing, instrumentation and other fields.
