Abstract

The invention relates to the technical field of heat exchangers, and provides a plate heat exchanger. The plate heat exchanger comprises a spiral structural part and multiple layers of heat exchange plates arranged in a stacked mode, through holes are formed in the heat exchange plates, the through holes of the multiple layers of heat exchange plates communicate with one another to form an inlet channel, inlets of fluid channels among the multiple layers of heat exchange plates communicate with the inlet channel, and the spiral structural part is arranged in the inlet channel. The spiral structural part is arranged in the inlet channel, vertical flowing of fluid in the inlet channel is converted into spiral flowing, the included angle between the flowing speed direction of the fluid and the heat exchange plates is reduced, and centrifugal force is generated; and the fluid enters each layer of fluid channel under the action of centrifugal force, so that the inlet resistance of the fluidentering the fluid channels is reduced, the problem of non-uniform flow of the fluid entering each layer of fluid channels is solved, and the heat exchange performance of the plate heat exchanger isimproved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a plate heat exchanger. Background technique [0002] Plate heat exchangers are widely used because of their high heat transfer efficiency, small heat loss, compact and lightweight structure, and small footprint. The plate heat exchanger is composed of a series of stacked heat exchange plates with a certain corrugated shape, and a fluid channel for the circulation of cold fluid and hot fluid is formed between each layer of heat exchange plates, and the cold and hot fluids pass through the heat exchange plates heat exchange. [0003] Each heat exchange plate of the plate heat exchanger is provided with two through holes at the corresponding positions. After stacking multiple heat exchange plates, two inlet channels of the plate heat exchanger are formed. After the hot fluid and the cold fluid are passed into different inlet channels respectively, they enter the fluid cha...
