Separation type microchannel capillary siphon type heat exchanger

Abstract

The invention discloses a separation type microchannel capillary siphon type heat exchanger. The separation type microchannel capillary siphon type heat exchanger comprises a housing, a separation type heat dissipation module and a draught fan device, wherein the separation type heat dissipation module comprises two single circuits which are respectively a self-driving circulation circuit and a pump-driven circulation circuit, the self-driving circulation circuit comprises a self-circulation condensation heat release unit, a self-circulation evaporation heat absorption unit, a self-circulationreturn pipe and a self-circulation ascension pipe, and the pump-driven circulation circuit comprises a pump-driven condensation heat release unit, a pump-driven evaporation heat absorption unit, a pump-driven ascension pipe, a drive pump return pipe and a drive pump arranged on the drive pump return pipe. The separation type microchannel capillary siphon type heat exchanger uses the dual circuitseparation type heat dissipation module which combines a driving mode and a driven mode together as the core, has the advantages of being strong in heat exchange ability, guaranteed in circulation driving force and good in isothermal effect, can efficiently discharge heat in a sealed equipment cabinet to the environment, and has good application prospects.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a separated microchannel capillary siphon heat exchanger. Background technique [0002] With the development of micro-electro-mechanical technology, electronic components present a development trend of high integration, small size, and high power consumption, which greatly improves the requirements of electronic systems on the heat dissipation capability of heat dissipation modules. For high-power communication cabinets that work outdoors and in factories, due to the harsh working environment, measures are usually taken to place the communication electronic system in a closed cabinet to prevent adverse environmental factors such as dust, humid air, and corrosive gases in the environment. To ensure the safe and stable operation of the communication electronic system. However, the heat dissipation environment in the airtight cabinet is harsh, and it is prone to the problem that the temperature ...

[0005] However, the existing heat pipe heat exchangers usually only use passive heat pipe cores. Under harsh working conditions such as extreme high temperature conditions, due to the high outdoor ambient temperature, the heat transfer temperature difference is too small and the heat dissipation effect is not good.
