Impingement plates are installed on the tube side of a bundle. It is between the tubes and the inlet nozzle and serves to slow down and/or disperse the liquid as it enters the exchanger. This prolongs the life of the tubes in this area which, in turn, extends the life of the bundle.

Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
Function of heat exchanger?
There are actually many types of plate heat exchangers, and the YOJO brand has introduced brazed plate heat exchangers and gasket plate heat exchangers. Today is the home of brazed heat exchangers.Brazed plate heat exchangers have no headers, tie rods or sealing gaskets, and the plates are brazed at a temperature of 1100 ° C. During the assembly stage, a piece of brazing material (usually copper, and nickel) is placed between the two plates, the package is compressed, and then baked for several hour.BPHE is more compact and lighter, and the brazing material has the functions of both washer and frame. The intersection between the corrugations of the two coupling plates forms a dense network of contact points, which impart pressure tightness and generate vortex flow, thereby improving heat exchange. In this way, even at low nominal input speeds, the turbulence of the fluid is high, and for low flow rates, the fluid flows from laminar to turbulent.
What does a heat exchanger fan do?
Dissipates the heat produced by the heat exchanger through convection and creates static and velocity pressure to distribute the hot air throughout the duct system.
What is the assumption to design heat exchanger?
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.
What is a furnace with a horizontal heat exchanger called?
air handler
