Abstract

The utility model relates to a machine cabinet grade liquid cooling device, which comprises a cabinet body. The liquid cooling device is characterized in that a liquid cooling unit is arranged in the cabinet body, an airflow orifice passage is arranged between the cabinet body and a machine cabinet, a fan is arranged in the airflow orifice passage, a gas to liquid heat exchanging core is arranged in the liquid cooling unit, the airflow orifice passage threads through the heat exchanging core, the heat exchanging core comprises a heat exchanging core pipe of flowing liquid cooling medium, and the heat exchanging core pipe is provided with an interface which is connected with a water-cooling device. The cooling ability of the machine cabinet can be intensified and the load on an indoor air conditioner is reduced.

Description

Rack level liquid cooling apparatus
(1) technical field
The utility model relates to the cooling device of the rack of communication equipment or supercomputer.
(2) background technology:
Along with improving constantly of communication equipment or supercomputer operation transmission speed, what follow is the hear rate that constantly promotes.As coolant, the fan by being installed in subrack bottom or top is as the power of Forced Air Convection with surrounding air for existing rack.By air the heat that electric elements in the subrack produce is discharged rack.Its shortcoming is:
1. cooling capacity is little, and for cooling machine cabinet, existing forced convertion cooling hear rate almost reaches capacity.
2. the caloric requirement in the rack diffuses in the room, has increased the burden of room air conditioning system.When center machine room air conditioner refrigerating arrives greatest limit, need increase equipment or, can can't satisfy the equipment dilatation because the system radiating ability is low, and then the system that influences moves normally existing equipment (rack) dilatation.
3. the noise height of fan generation can't satisfy the relevant criterion requirement.
(3) summary of the invention
The utility model will solve that existing rack cooling device heat-sinking capability is poor, heat diffuses to indoor shortcoming, and the rack level liquid cooling apparatus that a kind of heat-sinking capability is strong, heat diffuses to outdoor communication equipment, computer is provided.
Rack level liquid cooling apparatus described in the utility model, comprise cabinet, it is characterized in that the cabinet built-in is provided with liquid cooling unit, be provided with vent cap between cabinet and the rack, be provided with fan in the vent cap, be provided with the gas/liquid heat exchanger core in the described liquid cooling unit, described vent cap is by described heat exchanger core, described heat exchanger core comprise the working fluid refrigerant the heat exchanger core pipe, described heat exchanger core pipe has the interface that is connected with water cooling plant.
Further, set up a plurality of liquid cooling units on the described cabinet, be provided with dividing plate between the liquid cooling unit.
Further, the control circuit board of described fan is provided with thermistor, and described thermistor is arranged in the rack.
Operation principle of the present utility model: the hot-air that the equipment in the rack produces is extracted in the liquid cooling unit housing by fan by vent cap, heat exchange takes place in hot-air at gas/liquid heat exchanger core place, by heat exchange, the heat of hot-air is become cold air by Liquid Absorption and go out to discharge by wind deflector from the liquid cooling unit side plate openings and to enter the rack bottom.And raise because of absorbing the heat temperature by the cold liquid of heat exchange, the hot liquid that temperature raises is cooled in the water-cooling system of machine room by water pipe, and the liquid of cooling enters liquid cooling unit heat of cooling air again.
Technological merit of the present utility model:
1. cooling power is big, and the Single Cabinet cooling power reaches 25KW, and is bigger than traditional air cooling way.
2. the heat of rack directly is sent to outdoorly, has alleviated the burden of room conditioning.Even if the central machine room air conditioner refrigerating arrives greatest limit, still can increase equipment or to existing equipment (rack) dilatation, can adopt new equipment that the utility model cooling increases or by the equipment of dilatation, take to outside the machine room new equipment or by the heat of the equipment of dilatation by liquid cooling system, thus the normal operation of equipment in the assurance machine room.
3. according to concrete rack power consumption, can pass through the exchange capability of heat of the speed governing strategy adjustment heat exchanger of fan, save the fan power consumption, reduce noise.

Fig. 2 is the structural representation of the utility model when comprising a plurality of liquid cooling unit
Fig. 3 is the structural representation of heat exchanger core
(5) embodiment
With reference to accompanying drawing 1-3:
Rack level liquid cooling apparatus described in the utility model, comprise cabinet 1, be provided with some liquid cooling units in the cabinet 1, be provided with vent cap between the liquid cooling unit 3 in rack 11 and the cabinet 1, be provided with fan 5 in the vent cap, be provided with the finned gas/liquid heat exchanger core 4 of heat pipe in the described liquid cooling unit 3, described vent cap is by described heat exchanger core 4, described heat exchanger core 4 comprise the working fluid refrigerant heat exchanger core pipe 8 and corrugated fin, the water pipe groove, described heat exchanger core pipe 8 has the interface that is connected with water cooling plant, i.e. water inlet 9 and delivery port 10.
Look concrete rack power consumption, can be provided with a plurality of liquid cooling units 3, be provided with dividing plate 7 between the liquid cooling unit 3 at described cabinet built-in.The subrack 2 of described rack is outside equipped with wind deflector 6.
The control circuit board of described fan 5 is provided with thermistor, and described thermistor is arranged in the rack.Like this, can regulate the rotating speed of fan according to the temperature in the rack.
Fan 5 also can adopt aerofoil fan to be installed in exchange core bottom, adopts the blowing form to carry out heat exchange.
Operation principle of the present utility model: the Hot air quilt fan that subrack produced in the rack is extracted in the liquid cooling unit housing, heat exchange takes place in hot-air at gas/liquid heat exchanger core place, by heat exchange, the heat of hot-air is become cold air by Liquid Absorption and goes out to discharge the bottom that enters the subrack in the rack by wind deflector from the liquid cooling unit side plate openings.And raise because of absorbing the heat temperature by the cold liquid of heat exchange, the hot liquid that temperature raises is cooled in the water-cooling system of machine room by water pipe, and the liquid of cooling enters liquid cooling unit heat of cooling air again.
