Plate heat exchanger inlet flow uniformization and efficiency improvement device

Abstract

The utility model discloses a kind of plate heat exchanger inlet flow uniformity efficiency improving device, in plate heat exchanger fluid inlet and sheet core package between along fluid flow direction, first distribution header, flow uniformity device, secondary distribution header are sequentially arranged respectively;Secondary distribution header and the sheet flow passage inlet formed between each sheet form straight-through, fluid is directly passed through the flow passage inlet from secondary distribution header into the flow passage between sheet formed in sheet core package;Along fluid flow direction, at heat exchanger fluid inlet to fluid enters heat exchanger sheet core package interface position, install pressure, temperature, flow monitoring detection device, monitor and detect operating condition.The utility model carries out uniform redistribution to the fluid of heat exchanger inlet, and more evenly distributed on core package and sheet, can consider the temperature change of inlet fluid and the anti-impact of equipment.
