  • PLATE HEAT EXCHANGER PORT INSERT AND A METHOD FOR ALLEVIATING VIBRATIONS IN A HEAT EXCHANGER
    Publication number: 20120273178
    Abstract: An insert is provided in a flow path adjacent to the input and/or output port of a plate heat exchanger to shield heat transfer elements adjacent to the port from high velocity flow. By deflecting and redirecting the high velocity flow from the 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 narrowed body. The outlet of the insert can be formed as an open end of the body or as a contoured opening in the side wall of the body. Flow can also be more uniformly distributed to the flow channels defined between the heat transfer elements.
