Abstract

The invention relates to the field of application of microchannel heat exchangers, and particularly discloses a microchannel heat exchanger system. The microchannel heat exchanger system comprises a closed flowing channel located between a cold source and a heat source and a magnet outside the channel. Two or multiple phases of non-wetting fluid are closed in the channel. The flowing state of the multiple phases of fluid is bubble flow or slug flow. At least one phase of fluid in the multiple phases of fluid is magnetic fluid. Microchannel fluid drives the multiple phases of fluid to cyclically flow in the channel through the thermomagnetic effect of the magnetic fluid or with extra electromagnetic field force as drive force. The microchannel heat exchanger system is simple in structure; mixing and separating of multiple phases of fluid at an inlet and an outlet in conventional design are avoided; no rotary component is arranged in the system, and high reliability is achieved; and the system fully utilizes the heat transfer enhancement mechanism of heat convection of the multiple phases of non-wetting fluid in a microchannel, and the heat exchange efficiency of a microchannel heat exchanger is greatly improved.

Description

technical field [0001] The invention relates to the application field of microchannel heat exchangers, in particular to a microchannel heat exchanger system of non-wetting multiphase flow. Background technique [0002] With the wide application of micro-electro-mechanical and nano-devices in electronic biology and other fields, thermal design and thermal control of highly integrated micro-electronic devices and VLSI systems have become key issues for technological development and breakthroughs. Microchannel heat exchangers have application characteristics such as compact structure, large specific surface area, and high heat exchange efficiency. They have good application prospects in the above-mentioned chip and conventional air conditioning, refrigeration and other industries. [0003] Under micro-scale conditions, the fluid is basically in a laminar flow, and the radial mixing of the fluid only depends on molecular diffusion. For liquid fluids, this molecular diffusion is ...
