Problems solved by technology

[0003] At present, the cooling of the heating surface with ultra-high heat flux is generally treated with low-temperature refrigerant water, and the heat exchanger adopts a conventional heat exchanger. The refrigerant water only performs sensible heat exchange in the heat exchanger, and no phase change occurs. Lowering the temperature requires a large heat exchange area, and the cooling effect of the heating unit with ultra-high heat flux is limited. Failure to cool down well will reduce the service life of the equipment and pose a safety hazard

Embodiment Construction

[0012] As shown in the figure, a two-phase flow high-efficiency refrigeration device includes a circulating fluorine pump 1, a filter 2, an air-cooled condenser 3, a flow meter 4, a solenoid valve 5, a microchannel cooler 6, and a liquid reservoir 7 in sequence The refrigeration circuit formed by connecting the ends in series, the refrigerant is HF7100 with a freezing point of 60°C. The channel width of the microchannel cooler is 100-400μm, the channel height is 250-800μm, and the flow rate of the refrigerant entering the microchannel is 45m / s-55m / s. Under this condition, the heat flux density of the cooler reaches 400W / cm2.

[0013] The cooling principle of this refrigeration device is: the fluorinated liquid is transported to the filter 2 by the circulating fluorine pump 1 for filtration, then enters the air-cooled condenser 3 for heat exchange, cools the fluorinated liquid to a supercooled state, and passes through the flow meter 4 Monitor the flow rate of the fluorinated l...

Abstract

The invention relates to a two-phase flow efficient refrigeration device. The two-phase flow efficient refrigeration device comprises a refrigeration circuit which is formed through sequential end-to-end connection of a circulation fluoride pump, a filter, a condenser, a flowmeter, an electromagnetic valve, an evaporator and a liquid accumulator in series. The condenser is an air-cooled condenser,and the evaporator is a mirco-channel cooler.

Description

technical field [0001] The invention relates to the field of refrigeration devices, in particular to a two-phase flow high-efficiency refrigeration device. Background technique [0002] The two-phase flow high-efficiency refrigeration device refers to the equipment that can perform cooling operation under the requirements of the set working conditions, fully meet the temperature regulation of the ultra-high heat flux heating unit in terms of process requirements, and the heat flux density of the heat exchange surface reaches more than 400W / cm2 device. [0003] At present, the cooling of the heating surface with ultra-high heat flux is generally treated with low-temperature refrigerant water, and the heat exchanger adopts a conventional heat exchanger. The refrigerant water only performs sensible heat exchange in the heat exchanger, and no phase change occurs. The cooling of the temperature requires a large heat exchange area, and the cooling effect of the heating unit with ...
