Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, is expanded on further the present invention.
Referring to Fig. 1, a kind of self-cold and hot pipe heat radiation power cabinet air duct automatic switching device of the invention, including cabinet 5, upper strata
Heat-pipe radiator 2, lower floor's heat-pipe radiator 3, blower fan 12.Cabinet 5 include foreboard, back plate 5-2 and positioned at foreboard and back plate 5-2 it
Between intermediate plate；Foreboard includes upper foreboard 5-1-1 and lower foreboard 5-1-2, wind deflector 6 before lower foreboard 5-1-2 top is connected with；
Intermediate plate includes upper mid plate 5-3-1 and lower intermediate plate 5-3-2, and lower intermediate plate 5-3-2 top is connected with rear wind deflector 7；Before
Wind deflector 7 is (to ensure that preceding wind deflector 6, rear wind deflector 7 surround bearing 11 after wind deflector 6 is connected by front and rear wind deflector connecting rod 10
It is equidistant mobile).Upper strata heat-pipe radiator 2 is located at the first area between upper foreboard 5-1-1 and upper mid plate 5-3-1, lower floor's heat
Tube radiator 3 is located at the second area between lower foreboard 5-1-2 and lower intermediate plate 5-3-2；Blower fan 12 is located at lower floor's heat pipe heat radiation
The lower section of device 3.
In the present embodiment, levels respectively place three sets of heat-pipe radiators, levels heat in self-cold and hot pipe heat radiation power cabinet
Tube radiator is designed as independent ventiduct, the air inlet of air duct of upper strata heat-pipe radiator 2 middle part, lower floor's heat pipe heat radiation on front side of cabinet
The air inlet of air duct of device 3 is in cabinet lower front.
From under cold state, upper strata heat-pipe radiator 2 is entered by the middle part advance air port 9 on front side of cabinet and cabinet top air outlet 1
Row heat exchange；Air outlet 8 enters behind the middle part on rear side of bottom of cabinet air inlet 4 and cabinet that lower floor's heat-pipe radiator 3 passes through cabinet bottom
Row heat exchange.
The preceding lower end of wind deflector 6 is arranged on lower intermediate plate 5-3-2 by the good bearing 11 of lubricant effect, because of deadweight when self cooling
Fall by vertically through air channel separate as independent ventiduct, levels heat-pipe radiator carries out independent heat exchange with extraneous, not by
Affect one another.
When self-cold and hot pipe heat radiation power cabinet standby Thermal protection is acted, i.e., under air-cooled state, in the work of big flow blower fan 12
Under, preceding wind deflector 6 is blown afloat lifting, the wind deflector made using high thermal resistance material (from cold state when, lower air duct is warm in blockings
Exchange), it is ensured that wind deflector 6 can be raised to vertical position before when air-cooled.
Preceding wind deflector 6, rear wind deflector 7 are coupled by the front and rear wind deflector connecting rod 10 in the middle part of wind deflector, rotation section
Position is installed using the good bearing 11 of lubricant effect, is driven when current wind deflector 6 is blown lifting by front and rear wind deflector connecting rod 10
Wind deflector 7 is rotated from the front to the back afterwards, is ultimately at erectility.Now up and down independent ventiduct be changed into vertically through air channel, by
Cold air outside cabinet is pumped into cabinet by blower fan 12 from cabinet bottom air inlet, and hot-air is overflowed outside cabinet from cabinet top air outlet 1 in cabinet, is reached
To the effect that levels heat-pipe radiator is simultaneously air-cooled.
Present invention optimizes the air channel switched design under self cooling and air-cooled two operating modes of heat pipe heat radiation power cabinet, improve certainly
The electric current of exerting oneself of hot and cold tube heat radiation power cabinet, reduces IGCT because overheat causes the probability of thermal breakdown.
Referring to Fig. 2, preceding wind deflector 6, rear wind deflector 7 are designed arc-shaped appearance, and its curvature is 1/R, and radian is a, and arc is a width of
2Rsin α/2, the width is more than lower foreboard 5-1-2 tops and upper mid plate 5-3-1 lower ends catercorner length, it is ensured that preceding wind deflector 6
Independent ventiduct above and below lower air duct formation can completely cut off under cold state.Preceding wind deflector 6, rear wind deflector 7 are designed as having one
Determine radian, windage can be reduced, self-cold radiating is more beneficial for.From cold state when, preceding wind deflector 6, rear wind deflector 7 its own weight
In the presence of power, preceding wind deflector 6 and rear wind deflector 7 are fulcrum to rotating after cabinet with bearing 11, until above and below preceding wind deflector 6 covers
The interface channel in air channel, forms air outlet 8 behind middle part advance air port 9 and middle part, and upper strata heat-pipe radiator 2 passes through middle part advancing air
Mouth 9 and cabinet top air outlet 1 carry out heat exchange, and lower floor's heat-pipe radiator 3 is carried out by air outlet 8 behind bottom of cabinet air inlet 4 and middle part
Heat exchange.So levels heat-pipe radiator can possess separate air channel, and the temperature rise of upper strata heat-pipe radiator 2 is no longer by lower floor
The influence of the temperature rise of heat-pipe radiator 3.
Referring to Fig. 3, wind-force suffered by preceding wind deflector 6 can (K be air resistance coefficient, and S is front face area, and V is by formula F=K*S*V
Wind speed).When vertical position is fully achieved in current wind deflector 6, its front face area S is minimum, if now wind-force F suffered by preceding wind deflector 6min
Wind deflector deadweight G before and after ＞, you can wind deflector is after the startup of blower fan 12 before and after ensureing, the air-flow that can be raised is blown to vertical position,
So that upper lower air duct connection, radiates by forced air cooling to levels heat-pipe radiator.Now air inlet of air duct enters for bottom of cabinet
Air port 4, air outlet is cabinet top air outlet 1.Larger wind-force is obtained for wind deflector 6 before making, in addition to using big flow blower fan, wind-guiding
Plate is designed as curvature for 1/R, and radian is a arc, so as to obtain preferable front face area.Wind deflector and cabinet connecting portion
And front and rear wind deflector is connected with the connecting portion of front and rear wind deflector connecting rod 10 by lubricating preferable bearing 11, with prevent due to
The bite of rotating mechanism causes wind deflector action not in place.When blower fan 12 is switched to stop by operation, preceding wind deflector 6, rear wind-guiding
The design that plate 7 has radian can make it in the presence of self gravitation, fall naturally, again independent ventiduct above and below formation.
The present invention realizes levels IGCT component when heat pipe heat radiation power cabinet is in self-cold radiating state and possesses independence
The function of heat dissipation channel, improves the capacity under heat pipe heat radiation power cabinet self-cold radiating state.When heat pipe heat radiation power cabinet
Need open standby blower fan auxiliary heat dissipation when levels independence heat dissipation wind channel can be switched to again levels vertically through wind
Road, it is ensured that levels IGCT component is simultaneously air-cooled.
