Plate Heat exchanger is a new type of high efficiency heat exchanger which is stacked by a series of metal pieces with certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through half slices.
The type of plate heat exchanger mainly has frame type (detachable type) and brazing type two categories, the plate form mainly has the glyph corrugated plate, the horizontal straight corrugated plate and the tumor-shaped plate three kinds.
The following aspects should be considered in the manufacture of plate heat exchangers:
First, heat transfer area: is the heat change effect to meet the requirements. Second, the cost aspect: in general, we use the spiral plate heat exchanger because the manufacturing process is more complex than the plate, so in the site is small, heat exchange efficiency requirements are high place to use. And most of the use of stainless steel materials.
Third, anti-corrosion performance: Like you said oil and water, if the water contains more chloride ions, then the corrosion is very strong, so you use galvanized plate, it is also appropriate. Note that when used in the future, it is best to clean some of the water treatment.
This allows the heat exchanger to last a bit longer. Iv. strength: According to the use of pressure to determine, in general, there is no problem.
