Welded Plate Heat Exchanger belongs to Recuperative Heat Exchanger, and is fully welded between every two plates to form channels through which the fluids with different temperature can flow and exchange heat. The high temperature fluid transfers heat to the low temperature fluid through the plates, thereby realize heat exchanging. The flow velocity of each fluid can be controlled by plates distance, so as to meet the working condition perfectly. In addition, there is also the semi-welded type plate heat exchange.
Welded Plate Heat Exchanger is mainly for vapor condensing and liquid to liquid heat exchanging, to meet with various requirements from industries like power sector, petrochemical, petroleum coking, pharmacy, metallurgy, refrigeration, paper processing etc. Optimal arrangement of various channels also make sure of high heat transfer efficiency and minimal pressure loss. Besides, its frame is detachable, and therefore it is convenient to have either mechanical cleaning or chemical cleaning as per actual situations.
