Plate heat exchanger and method for distributing flow evenly

Abstract

The application discloses a plate heat exchanger and a flow uniform distribution method thereof, and mainly relates to the field of radiators. The plate heat exchanger comprises a plurality of heat exchange plates arranged in layers and a plurality of fins arranged between adjacent heat exchange plates, a heat exchange layer is formed between the adjacent heat exchange plates, the heat exchange layer comprises an oil liquid heat exchange layer and a cooling liquid heat exchange layer, and the plate heat exchanger further comprises a flow guide module arranged between the adjacent heat exchange plates and in limiting cooperation with the fins, which is used for positioning and supporting the heat exchange plates and the fins. The flow guide module is provided with a flow guide structure in communication with the heat exchange layer where the flow guide module is arranged, and the flow guide structure is used for changing the local flow state of the heat exchange layer. The plate heat exchanger has the beneficial effects that the standardized flow guide module with the functions of positioning and supporting and flow regulation is arranged in the heat exchange layer, and the number, arrangement position and flow guide parameters of the flow guide module are configured according to the deviation between the initial flow and the target flow of each heat exchange layer.
