In order to make it easy to understand, the invention will be further described with reference to the accompanying drawing.
Referring to FIG. 1 to FIG. 5, Fig. 1 is a kind of facing for power supply heat sinking device for vehicle provided in an embodiment of the present invention
Figure, Fig. 2 are the top views of power supply heat sinking device provided in an embodiment of the present invention, and Fig. 3 is that power supply provided in an embodiment of the present invention dissipates
The rearview of thermal, Fig. 4 are A-A cross-sectional views in Fig. 2, and Fig. 5 is B-B cross-sectional view in Fig. 2.
Power supply heat sinking device provided in an embodiment of the present invention for vehicle includes cabinet 1, is provided in cabinet 1 for pacifying
The partition of power module 3 is filled, partition is horizontal to divide cabinet 1 for upper and lower part in cabinet 1, and power module 3 is located at cabinet 1
Multiple equidistant cooling fins 8 side by side on top, power module 3 are reached straight down in the heat dissipation wind channel of 1 lower part of cabinet, are radiated
The radiating surface of piece 8 and the front-rear direction of vehicle are parallel, and two sides of the heat dissipation wind channel on vehicle front-rear direction offer heat exchange mouth 4,
And be provided at the heat exchange mouth 4 of at least side can positive and negative rotation fan 5.
Since the heat exchange mouth 4 of heat dissipation wind channel is located at the two sides on vehicle front-rear direction of cabinet 1, so in vehicle driving
The traveling wind that can be generated in real time using vehicle movement in the process achievees the effect that strengthen power supply heat sinking.Meanwhile at least side
Heat exchange mouth 4 at be provided with fan 5, and fan 5 can positive and negative rotation, so when controlling the power supply heat sinking device, Ke Yitong
The flabellum rotation for crossing control fan 5, makes the inlet side of fan 5 towards the side of vehicle windward side, this makes it possible to avoid wind
The problem of 5 outlet air are obstructed is fanned, achievees the effect that strengthen power supply heat sinking by the forced convertion heat dissipation of fan 5.
As shown in Figure 2 and Figure 5, in the present embodiment, there are two power modules 3 in cabinet 1, and each power module 3 is below
It is corresponding with one group of cooling fin 8, each cooling fin 8 is parallel to each other, arranges at an equal pitch, looks over from the visual angle of Fig. 5, heat dissipation
Piece 8 is just as the tooth of comb.
Cooling fin 8 is located in heat dissipation wind channel, and wind is flowed through from heat dissipation wind channel, and heat is taken away.In specific practical application, heat dissipation
Spacing of the distance generally between two neighboring cooling fin 8 of the lower edge of piece 8 to the bottom surface of heat dissipation wind channel is equal.
After power module 3 is installed on the partition of cabinet 1, between cooling fin 8 and the side of heat dissipation wind channel and two groups dissipate
Between backing 8 there are space it is usually wider much than the space between two neighboring cooling fin 8, in order to make each space as far as possible
Wind speed it is consistent, to guarantee 3 Homogeneouslly-radiating of power module, can use guide plate for wide space and block a part.Such as Fig. 4 and figure
Shown in 5, it is both provided with flipper guide 6 between every group of cooling fin 8 and the side of heat dissipation wind channel, is provided between two groups of cooling fins 8
Guide plate 7, flipper guide 6 and centering guide 7 are parallel with cooling fin 8, and the top edge of flipper guide 6 and centering guide 7 is fixedly connected with partition,
And the lower edge of flipper guide 6 and centering guide 7 is dissipated to the distance of the bottom surface of heat dissipation wind channel, flipper guide 6 and centering guide 7 with outermost
The distance between the side of the distance between backing 8 and flipper guide 6 and heat dissipation wind channel be equal to two neighboring cooling fin 8 it
Between spacing.
In order to protect the cooling fin 8 and fan 5 in heat dissipation wind channel, it generally is provided with shutter 2 at heat exchange mouth 4, such as Fig. 1
It is shown.It should be noted that the two sides of heat dissipation wind channel are provided with shutter 2, but Fig. 3 is in order to show heat exchange mouth 4 not by blinds
Window 2 is drawn.
Based on power supply heat sinking device of the invention, the present invention also provides a kind of controls of power supply heat sinking device for vehicle
Method processed, the control method include: that when the vehicle is running, the flabellum rotation of control fan 5 makes the inlet side fan 5 of fan 5
Towards the side of vehicle windward side.
For rail vehicle, usually all can with two way, due to fan 5 can positive and negative rotation, so wind
The inlet side of fan 5 can change, and in above-mentioned control method, the inlet side of fan 5 is set according to the driving direction of vehicle,
That is the inlet side of fan 5 is always side of the fan 5 towards vehicle windward side, conduct when " vehicle windward side " refers to vehicle driving
The side of front end.
Since the inlet side of fan 5 is always side of the fan 5 towards vehicle windward side, so can make full use of vehicle
The traveling wind generated when driving improves the heat dissipation air quantity of power module 3, heat dissipation effect is made to get a promotion.
In stationary vehicle but in the case where not flame-out, power module 3 still has the demand of heat dissipation, therefore, above-mentioned control method
It can also include: that when the vehicle is still, the flabellum rotation of control fan 5 makes the inlet side fan 5 of fan 5 towards in cabinet 1
The side in portion.
