Cooling Plate Heat Exchangers, Titanium Alloy, Honest Business Practices, Genuine Materials. The plate-type cooler is a new type of heat exchanger composed of a series of metal plates with a certain corrugated shape stacked together. The thin rectangular channels between various plates are formed for heat exchange through semi-plates. Compared to the conventional tube-and-shell heat exchangers, it has a much higher heat transfer coefficient under the same flow resistance and pump power consumption, showing a trend to replace the tube-and-shell heat exchangers within its applicable range. The main types of plate heat exchangers are frame-type (detachable) and brazed-type, with three main plate shapes: V-shaped corrugated plates, horizontal straight corrugated plates, and nodular plates.
