The external cold air is absorbed by the blower, and the heat radiation aluminum strips which are internally embedded in the shell are subjected to forced cooling heat radiation through the heat radiation air channels on the inner side of the shell, so that the problems of incapability of dissipating heat from the shell in time due to temperature rise in a natural heat radiation way and incapability of isolating internal and external environments in the conventional air cooling heat radiation way are solved, and good waterproof and moistureproof functions are realized.
Description
Technical field
The housing with heat sinking function of the controller that the present invention relates to use in a kind of electric motor car.
Background technology
Existing market electric vehicle middle low power controller adopts housing natural heat dissipation mode mostly, this mode because can not be in time, heat radiation fully, very easily cause the interior high temperature of controller, cause controller line board component degradation, the lost of life.The high-power controller of part then adopts traditional wind-cooling heat dissipating mode; It is directly to controller line board component blowing heat radiation through outside blower fan; Because internal and external environment can't be isolated, and causes the controller line board component very easily to receive contamination by dust and premature damage, and can't realize waterproof and dampproof.
Summary of the invention
The purpose of this invention is to provide a kind of perfect heat-dissipating, and have the controller for electric vehicle housing of good closure.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
A kind of controller for electric vehicle housing; Its main body is an aluminum enclosure, and aluminum enclosure is the cylindrical shell that cross section is square, and the two ends of aluminum enclosure are divided in addition by front apron, backboard sealing; Blower fan is installed on the backboard; Wiring board is fixedly connected on the inwall of aluminum enclosure, it is characterized in that: the sidewall upper edge aluminum enclosure length direction in aluminum enclosure has heat dissipation wind channel, and heat dissipation wind channel runs through the aluminum enclosure sidewall; Have in aluminum enclosure on the medial surface of sidewall of heat dissipation wind channel and be connected with the heat radiation aluminum strip, the CMOS power tube is connected on the heat radiation aluminum strip.
Above-mentioned a kind of controller for electric vehicle housing is characterized in that: heat dissipation wind channel is vertically disposed a plurality of passage, and each passage all is level and is parallel to each other.
Above-mentioned a kind of controller for electric vehicle housing; It is characterized in that: distinguished and admirable steering structure spare is installed between backboard and aluminum enclosure, and distinguished and admirable steering structure spare one side is caved in, and in the part of caving in blower fan is installed; Distinguished and admirable steering structure spare opposite side has exhaust vent; The exhaust vent position is corresponding with heat dissipation wind channel, and exhaust vent is from high to low skewed to the distinguished and admirable steering structure spare base plate between the motor, and the distinguished and admirable steering structure spare base plate of inclination and backboard constitute the blower fan air channel; Have the wind hole with the position of corresponding blower fan on the baffle plate that distinguished and admirable steering structure spare connects.
Above-mentioned a kind of controller for electric vehicle housing, it is characterized in that: the medial surface that has the sidewall of heat dissipation wind channel in aluminum enclosure has groove, and the heat radiation aluminum strip is fixed in the groove.
Above-mentioned a kind of controller for electric vehicle housing is characterized in that: blower fan adopts centrifugal blower.
Cold wind is discharged via wind hole, blower fan air channel, exhaust vent, heat dissipation wind channel under the effect of blower fan; Gas stream is taken away heat through heat dissipation wind channel; The design of array heat dissipation wind channel adds that the heat radiation aluminum strip is embedded in and has all increased heat exchange area in the aluminum enclosure, has improved radiating effect.
The present invention in the heat radiation of electric vehicle controller, adopts wind-tunnel wind tunnel theory application the array air channel to carry out the air blast cooling heat radiation.It draws cool exterior air through embedded blower fan, and the heat radiation aluminum strip of adorning in to housing through the inboard heat dissipation wind channel of housing carries out the air blast cooling heat radiation.Promptly solved the too high and difficulty that can't in time dispel the heat of temperature rise in the housing natural heat dissipation mode; Solve the problem that traditional wind-cooling heat dissipating mode internal and external environment can't isolate again and realized the excellent waterproof moisture-proof function, reasonably in the ratio of performance to price electric vehicle controller radiating efficiency has been improved 6～8 times.
The present invention adopts full aluminum enclosure, highly integrated air blast cooling heat radiation and waterproof and dampproof two big functions; Compact conformation is reasonable; The blower fan control chip is selected special DSP for use, realizes the accurate control to blower fan; Possess extremely strong on-line monitoring and fail safe.
Product of the present invention is through function and performance test (outer characteristic, efficient distribution map), environmental suitability test (high temperature and high-temperature circulation test, the experiment of temperature cycles operation test water proof and dust proof, anti-vibration test), reliability test (bad working environments under accelerated life test and high and low temperature impact test); And pass through to contrast with the actual radiating effect of other electric vehicle controller; Through checking; This controller heat dissipation design technical scheme is rational in infrastructure, heat radiation is good; High temperature resistance, waterproof, anti-moist ability are strong, satisfy the requirement of long-term stable operation.
