Brazed plate heat exchanger has the advantages of no gasket, no leakage, light weight, small size, low price, easy disassembly and installation, and high heat transfer efficiency. The structure is suitable for steam, water or process fluids and can be used with minimal temperature difference between the two fluids.

How to prevent uneven stress of brazed plate heat exchanger tube bundle?
Brazed plate heat exchangers are made of a number of stamped corrugated sheets arranged at corresponding intervals, which are sealed with washers and superimposed with frame and pressing screws. The four corner holes of the plate and the gasket form a fluid distribution tube and a collection tube, and the hot and cold fluids are reasonably separated in the flow channels on both sides of each plate to flow through the plate for heat exchange.

First, position the lifting lug of the brazed plate heat exchanger so that the slide of the heat exchanger is in the stress position (and vertical direction), withstand the gravity of the heat exchanger, avoid direct stress on the tube bundle, and avoid the baffle scratch the shell. Secondly, in the process of lifting the plate and shell heat exchanger, the levelness of the positioning ear should be maintained at the same time, so that the tube bundle is not vertically compressed. In brazed plate heat exchangers, there are two main heat transfer modes: conduction and convection. The hot fluid transfers heat to one side of the tube wall through convection, and then transfers heat from one side to the other side through conduction, and the other side of the tube wall transfers heat to the cold fluid through convection, thus completing the heat transfer process of the heat exchanger.
