The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
It refer to a kind of vehicle-mounted distribution box for improving heat dispersion in Fig. 1-Fig. 3, the present embodiment, including casing 2 and case lid
1, the case lid 1 is connected by sealing ring with the casing 2；It is not provided with connecting between heat emission hole, and case lid 1 and casing 2 on casing 2
Place is provided with sealing ring, it is ensured that the overall sealing of distribution box, it is to avoid the trickle material such as extraneous dust enters influence in casing 2
The performance of part.
The inner chamber of casing 2 is provided with rectification module 261, high voltage power distribution module 251, modular converter 262 and heat-dissipation spacer 24；
The inner chamber of the casing 2 is separated into thermal source chamber 26 and nonrefractory chamber 25 by the heat-dissipation spacer 24, and the nonrefractory chamber 25 is located at
The top of the thermal source chamber 26；The rectification module 261 and the modular converter 262 are in the thermal source chamber 26, the height
Power entry module 251 is pressed in the nonrefractory chamber 25.
Modules in existing distribution box are all coupled, this arrangement, various pieces can be made mutual
Influence, and if there is part to be damaged, multiple functions can be impacted.In the present invention, rectification module 261, height in distribution box
Press Power entry module 251 and modular converter 262 separate, be damaged even if some module and also do not interfere with other modules.
Simultaneously as rectification module 261 and modular converter 262 can all produce substantial amounts of heat when in use, but constitute high
The element for pressing Power entry module 251 is generally nonrefractory material, therefore is separated the inner chamber of the casing 2 by the heat-dissipation spacer 24
Into thermal source chamber 26 and nonrefractory chamber 25, effectively heat source module and nonrefractory module can be isolated, it is to avoid influence each other.
Because hot-air is usually the layer shell temperature of distribution box if thermal source chamber 26 is located at into upper strata toward rising
Degree is just very high, and thermal source chamber 26 is located at into lower floor, and the conduction of heat of intermediate radiator dividing plate 24, first on casing 2 dissipate in addition
The thermolysis of backing and the second fin 222, is conducive to dispersing for the temperature of casing 2.
One of described 2 four sides of casing are provided with some wiring ports 23, and the distribution port is used to connect described
The input-output line of rectification module 261, the high voltage power distribution module 251 and the modular converter 262, each module passes through with line end
Mouth 23 is connected with external equipment.
Wherein other three face in 2 four sides of casing is equipped with the first radiating group 21, and the bottom surface of casing 2 is provided with second
Radiating group 22.
The first radiating group 21 includes some first fin, length, width and the height point of first fin
Wei not 180mm, 6mm and 10mm；The plane perpendicular of the length direction of first fin and the casing 2, and described first
The short transverse of fin is vertical with the side of the casing 2 at place；It is two neighboring in each first radiating group 21
The spacing of first fin is 15mm.
222 groups of second fin includes some heat-sink units 221, and the length direction of the heat-sink unit 221 is vertical
The side of the distribution port is provided with the casing 2；The spacing of the two neighboring heat-sink unit 221 is 15mm；It is described to dissipate
Hot cell 221 includes some second fin 222, the length of second fin 222, width and height be respectively 20mm,
6mm and 10mm；The side institute of the length direction of second fin 222 and the casing 2 provided with the distribution port is into folder
Angle number is 40 ° -50 °, and the short transverse of second fin 222 is vertical with the side of the casing 2 at place；Each institute
The spacing for stating two neighboring second fin 222 in heat-sink unit 221 is 15mm.
Traditional distribution box is radiated by heat emission hole, and the present invention is not set on the sealing for ensureing distribution box, casing 2
There is heat emission hole, but radiated by setting fin on casing 2.In order to verify that the radiating effect of distribution box is good,
We verify the heat dispersion of distribution box of the present invention by software emulation.The second fin 222 wherein on bottom surface have laterally,
Longitudinal direction, oblique three kinds of arrangement modes, in emulation experiment, can be found by simulation result, when the second fin 222 on bottom surface is oblique
To during arrangement, preferably, simulation result figure is as Figure 4-Figure 6 for radiating effect.
In the present embodiment, the heat-dissipation spacer 24 is rectangle, and the corner of the bottom surface of heat-dissipation spacer 24 is respectively by vertical
Post 241 is connected with the bottom surface of the inner chamber of casing 2, and described 24 4 sides of heat-dissipation spacer are supported with the intracavity sidewall of casing 2
Connect；The thickness of the heat-dissipation spacer 24 is 7mm-9mm, and the heat-dissipation spacer 24 and the bottom surface distance of the inner chamber of casing 2 are institute
State the 3/5 of the depth of casing 2.
In this implementation, heat-dissipation spacer 24 is dismountable, is connected by four columns 241 come the bottom surface with the inner chamber of casing 2,
The ratio of thermal source chamber 26 and nonrefractory chamber 25 can be changed by adjusting the length of column 241.Four sides of heat-dissipation spacer 24
Abutted with the intracavity sidewall of casing 2, can prevent the heat in thermal source chamber 26 from entering nonrefractory chamber 25, make the isolation of heat-dissipation spacer 24
Effect is more preferable, while also making the heat of heat-dissipation spacer 24 preferably be delivered on the first fin of the side of casing 2.Heat-dissipation spacer
24 will have certain thickness, it is to avoid when the heat of thermal source chamber 26 is too high, heat can be delivered to nonrefractory chamber by heat-dissipation spacer 24
25, through emulation testing, when the thickness of the heat-dissipation spacer 24 is 7mm-9mm, effect of heat insulation is best.Heat-dissipation spacer 24 and casing 2
The bottom surface distance of inner chamber is moderate；Distance is too small to influence radiating, the distance too conference influence volume of casing 2, while heat-dissipation spacer
24 presence can also make to form thermal convection current in thermal source chamber 26, the radiating of distribution box be further speeded up, by multiple actual test
And software emulation, radiating effect when heat-dissipation spacer 24 and the bottom surface distance of the inner chamber of casing 2 are the 3/5 of the depth of casing 2
It is best.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements done etc. should be included within the scope of protection of the invention.
