Referring to Fig. 2 and 3, in embodiment, the upper end of heat dump 1 is provided with upper header 13 and lower end is provided with lower header 14,
The upper end of the radiator 2 is provided with upper collecting pipe 21 and lower end is provided with lower collecting pipe 22, the upper header 13 and upper collecting pipe
It is connected between 21 by some gaseous working medium tube channels 3, by some between the lower header 14 and lower collecting pipe 22
Bar liquid refrigerant tube channel 4 is connected, filled with meeting by thermal evaporation heat-transfer working medium in the heat dump 1.When in communications equipment room
After air stream is by heat dump 1, heat transfer to heat-transfer working medium and is allowed to gasify by heat dump 1, and the heat-transfer working medium of gasification is through gaseous state
Working medium passage pipe 3 enters radiator 2, and after outer cold air takes away the heat in radiator 2, heat-transfer working medium liquefies and made by gravity
With backflow, it is flow to through liquid refrigerant tube channel 4 in lower header 14, according to this reciprocation cycle, heat exchange efficiency is high, and radiating is more efficient,
Arrow show air flow in accompanying drawing.
Specifically, heat dump 1 includes some heat absorption micro-channel tubes 11 and is entrained between heat absorption micro-channel tubes 11
Heat absorbing fins 12, be specifically, heat absorption micro-channel tubes 11 length direction at a certain distance along upper and lower header arranged radially,
And in the compartment hole that the termination insertion for the micro-channel tubes 11 that absorb heat is arranged on upper and lower header 14 respectively, while inhaling
Sandwich heat absorbing fins 12 between hot micro-channel tubes 11, and through tie up it is fixed-type after soldering shape, to form the heat absorption of heat dump 1
Core body, the heat-transfer working medium are arranged in heat absorption micro-channel tubes 11, and heat-transfer working medium is also filled with lower header 14, so hot
Transmission effect is more preferable.
Meanwhile the radiating fin that radiator 2 includes some radiating micro-channel tubes and is entrained between radiating micro-channel tubes
Piece, radiator 2 is similar to the preparation method of heat dump 1, forms the radiating core of radiator 2, and the tool of radiator 2 is not shown in accompanying drawing
Body structure, radiating fin are made using aluminium, and radiating effect is notable.
In embodiment, the both ends of gaseous working medium tube channel 3 are welded with upper header 13 and upper collecting pipe 21 respectively, liquid work
Welded respectively with lower header 14 and lower collecting pipe 22 at the both ends of matter tube channel 4.Wherein, the making of gaseous working medium tube channel 3
Cheng Shi, on the radial direction tube wall of upper header 13 and upper collecting pipe 21, along the individual straight of the quantity such as the opposite symmetrical machining of a certain angle
Footpath is R circular hole, and the pipe of certain length is respectively welded at circular hole, and the fixed length pipe is the gaseous working medium of heat-transfer working medium
Tube channel 3.Liquid refrigerant tube channel 4 is similar to the production method of gaseous working medium tube channel 3.Welded in liquid refrigerant tube channel 4
After the completion of, the circular hole of the minor diameter of Drilling operation one in a certain bar liquid refrigerant tube channel 4, while a minor diameter is welded here
Fixed length copper pipe and while heat dump 1 and radiator 2 are vacuumized by the copper pipe, inject a certain amount of heat-transfer working medium, so
Fixed length copper pipe is pressed from both sides into flat welded seal afterwards, so completes the encapsulation of heat-transfer working medium.
In order to effectively improve heat transfer effect, seal isolation plate 5 is set between heat dump 1 and radiator 2, and is consequently formed
Relatively independent, sealing heat sink region and heat dissipation region；Heat sink region where heat dump 1 forms circulate in the wind road, radiator 2
Place heat dissipation region forms outer circulating air duct, and first cooling fan 6 is located in circulate in the wind road, second cooling fan
7 in outer circulating air duct.
When temperature is too high in communications equipment room, the first cooling fan 6 and the intervention work of the second cooling fan, the first cooling wind
After hot-air in the suction communications equipment room of fan 6, heat absorbing fins 12, which absorb heat and are conducted to heat absorption micro-channel tubes 11, to be caused in its cavity
Heat-transfer working medium gasification, heat-transfer working medium after gasification passes through the upper collecting pipe 21 that gaseous working medium tube channel 3 enters radiator 2；So
Radiating micro-channel tubes and the radiating fin heat being conducted to afterwards on radiator 2, now the second cooling on radiator 2
Fan 7 sucks the Cryogenic air outside rack, by cooling down radiating fin and radiating micro-channel tubes, causes the microchannel tube chamber that radiates
Internal heat-transfer working medium gas cools and is allowed to condense, and condensed liquid enters liquid refrigerant tube channel along radiating micro-channel tubes
4 and conflux with lower header 14；The heat-transfer working medium in the presence of the heat, cold air stream of heat dump 1 and radiator 2, constantly with
The reciprocal natural circulation mode of liquid-gas-liquid, air is constantly cooled in such communications equipment room cavity, reaches the effect that cools.
During installation, the blowing direction of the first above-mentioned cooling fan 6 is perpendicular to the plane where heat dump 1, the second cooling
The blowing direction of fan 7 perpendicular to the plane where radiator 2, i.e., fan blade rotary shaft respectively with heat dump 1 and radiator 2
Core body plane it is vertical, therefore enhance the efficiency of heat exchange.First cooling fan 6 and the second cooling fan 7 can design peace
In the space among heat dump 1 and radiator 2, when fan is when breaking down, it can take out in space, carry out
Safeguard or change.In addition, setting standby battery in computer room, when there is power supply trouble, switching battery cools down to first
The cooling fan 7 of fan 6 and second is powered, and the stabilization of communications equipment room operating temperature is effectively ensured.
It is described above, simply presently preferred embodiments of the present invention, the invention is not limited in above-mentioned embodiment, as long as
It reaches the technique effect of the present invention with identical means, should all belong to protection scope of the present invention.
