Abstract

The invention relates to a micro-channel heat exchanger and a flow heat exchange experiment device. The micro-channel heat exchanger is characterized in that the heat exchanger at least comprises an upper cover plate and a lower cover plate; three flow channels, namely, a first flow channel, a second flow channel and a third flow channel, and the inlets and outlets of the three flow channels are machined on the upper cover plate and the lower cover plate respectively; the first flow channel, the second flow channel and the third flow channel are each composed of two Y-shaped flow channels; the first flow channel and the third flow channel are formed by connecting the bifurcate ends of two Y flow channels, and the second flow channel is formed by connecting the non-bifurcate ends of two Y flow channels; and when fluid flows in the first flow channel, the second flow channel and the third flow channel, the flow direction at the inlets and the flow direction at the outlets are perpendicular to each other. The heat dissipation performance is good. Electronic equipment of high heat flux density can be kept at uniform temperature.

Description

technical field [0001] The invention relates to the fields of microchannel heat dissipation and liquid metal heat dissipation, in particular to a microchannel heat exchanger and a flow heat exchange experimental device. Background technique [0002] With the rapid development of technologies such as micro-electro-mechanical systems and ultra-large-scale integrated circuits, the volume of electronic equipment is getting smaller and smaller, while the power and integration are greatly improved. The generation of high heat flux has become an irresistible trend. If If the heat cannot be taken away quickly, the electronic devices will not work normally due to high temperature, or even burn out. In addition to ensuring the temperature of the electronic products is low, the heat dissipation effect also needs to reduce the temperature difference between the components of the electronic products. Traditional heat dissipation methods can no longer meet the heat dissipation requirement...
