The embodiment of the invention relates to the technical field of heat exchangers and provides a heat exchanger for a printed circuit board. The heat exchanger for the printed circuit board comprisesa spiral structural part and multiple layers of heat exchange plate sheets arranged in a stacked manner. The heat exchange plate sheets are provided with through holes, the through holes of the heat exchange plate sheets communicate to form an inlet channel, an inlet of a fluid channel between the heat exchange plate sheets communicates with the inlet channel, and the spiral structural part is arranged in the inlet channel. By arranging the spiral structural part in the inlet channel, vertical flow of the fluid in the inlet channel is converted into spiral flow, so that the included angle between the flowing speed direction of the fluid and the heat exchange plate sheet is reduced and a centrifugal force is generated. Under the action of the centrifugal force, the fluid enters the fluid channels of all layers, so that the inlet resistance of the fluid entering the fluid channel is reduced, the problem that the fluid flow of the fluid channel of each layer is not uniform is solved and the heat exchange performance of the heat exchanger for the printed circuit board is improved.
Description
technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a printed circuit board heat exchanger. Background technique [0002] The printed circuit board heat exchanger is made by stacking and welding the heat exchange plates engraved with fine channels by diffusion welding technology. It has the characteristics of compact structure and strong pressure bearing capacity. Broad application prospects. [0003] Each heat exchange plate of the printed circuit board 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 channels between the heat exchange plates of each layer from the inlet channels. However, since the velocity direction of the fluid at the inlet end of the inlet channel is ...
