PLATE HEAT EXCHANGER PORT INSERT AND A METHOD FOR ALLEVIATING VIBRATIONS IN A HEAT EXCHANGER

摘要

An insert is provided in a flow path adjacent to the input and/or output port ofa plate heat exchanger to shield heat transfer elements adjacent to the port fromhigh velocity flow. By deflecting and redirecting the high velocity flow fromthe port, vibration induced stress to the heat transfer elements can be minimized.The insert is provided with a converging nozzle that directs the flow into a narrowedbody. The outlet of the insert can be formed as an open end of the body or as a contouredopening in the side wall of the body. Flow can also be more uniformly distributedto the flow channels defined between the heat transfer elements.
