Abstract

The manifold micro-column array flat plate heat exchanger is sequentially provided with a fluid inlet and outlet layer, a manifold flow dividing layer and a micro-column array layer from top to bottom, the fluid inlet and outlet layer comprises an upper face and a lower face, a fluid inlet and a fluid outlet are formed in the upper face, and a fluid inlet runner and a fluid outlet runner are arranged on the lower face. The fluid inlet is communicated with the fluid inlet runner, the fluid outlet is communicated with the fluid outlet runner, the fluid inlet runner is arranged at the first end of the lower surface and extends along the first end in the first direction, and the fluid outlet runner is arranged in the middle of the lower surface and extends in the direction perpendicular to the fluid inlet runner. According to the flat plate heat exchanger, microminiaturization can be achieved, the number of the inlet manifold inflow channels is two, the number of the inlet manifold inflow channels is two, then the fluid impacts in the inlet manifold, impact of the fluid on the microcolumn array layer can be strengthened, and the overall heat dissipation performance is improved.

Description

technical field [0001] The invention relates to a heat exchanger technology, in particular to a flat plate heat exchanger, which belongs to the heat pipe field of F28d15 / 02. Background technique [0002] A heat exchanger is a device that exchanges heat between hot and cold fluids, also known as a heat exchanger. Heat exchangers are widely used in many fields. In fields such as electronics, petrochemicals, communications, aerospace and other fields, due to their special working scenarios, there are special requirements for the size and weight of the heat exchanger, and it is required to have a stronger heat exchange capacity. [0003] In 1981, some scholars proposed the use of microchannels for heat dissipation, which can not only reduce the volume of the heat exchanger, but also greatly increase its heat transfer capacity by using the higher specific surface area of ​​the microchannels. However, although its heat exchange capacity is strong, the overall pressure loss of th...
