Abstract
The invention relates to a motor controller, which belongs to the technical field of new energy automobile electronic control, and mainly solves the fixing and radiating problems of a non-inductive absorbing capacitor inside the existing motor controller, and the problem that cooling liquid is low in radiating efficiency when flowing through a smooth water channel under a liquid cooling radiating mode. The motor controller is mainly characterized by comprising a shell, and a shielding iron plate and an IGBT driving module, a driving circuit board, a control circuit board, a film capacitor, a current sensor, a non-inductive absorbing capacitor, a bus bar support and a bus bar which are arranged in the shell, the housing of the shell beside the bus bar support is provided with a groove matched with the non-inductive absorbing capacitor in shape, the non-inductive absorbing capacitor is positioned in the groove, and a baffle for covering the non-inductive absorbing capacitor is arranged on the bus bar support. The motor controller has the characteristics of improving anti-vibration performance and radiating efficiency of the product, and is mainly applied to pure electric motors.
Description
Technical field
The invention belongs to new-energy automobile electron controls technology field.Be specifically related to a kind of pure electric motor controller-E30L electric machine controller.
Background technology
As one of pure electric automobile three large core components, the designing technique of electric machine controller plays decisive role to whole electric motor car runnability.Existing electric machine controller is generally made up of shell and the shielding iron plate, busbar, IGBT driver module, driver circuit plate, control circuit board, thin-film capacitor, current sensor and the noninductive Absorption Capacitance that are loaded in shell, wherein noninductive Absorption Capacitance is generally fixed on bus busbar top, be suspended in midair, be not easy to fixing and heat radiation, fragile under vibration and worst hot case.Fluid-cooled electrical machine controller adopts the scheme that designs level and smooth water channel at housing bottom conventionally in addition, when cooling fluid is flowed through water channel, easily on waterway wall, produces moisture film, impact heat radiation.
Summary of the invention
The object of the invention is exactly the pure electric motor controller of Based Intelligent Control electronics device-E30L that a kind of drive motors running is provided for above-mentioned weak point.
Technical solution of the present invention is: a kind of electric machine controller, comprise shell and be loaded on shielding iron plate, IGBT driver module and driver circuit plate, control circuit board, thin-film capacitor, current sensor and noninductive Absorption Capacitance, busbar support and the busbar in shell, it is characterized in that: the described other case body of busbar support is provided with the groove with noninductive Absorption Capacitance form fit, noninductive Absorption Capacitance is positioned at this groove, and busbar support is provided with the baffle plate that covers noninductive Absorption Capacitance.
Outer casing bottom described in technical solution of the present invention is provided with water channel, and these water channel two ends are respectively equipped with water inlet and delivery port, are provided with protruding turbulence columns in water channel.
The center line setting that a turbulence columns part described in technical solution of the present invention flows to along water channel, another part is arranged on the sidewall of water channel.
The present invention is owing to being fixed on the basis on busbar top at existing noninductive Absorption Capacitance, changed in the housing groove being fixed on below busbar, and use baffle plate to cover groove top, the noninductive Absorption Capacitance that is positioned at groove is reliably fixed, can stop it to shake up and down, and capacitive surface contacts with housing, can improve the thermal diffusivity of electric capacity, effectively avoid the damage of electric capacity because causing under vibration and worst hot case.The present invention is due at housing bottom water channel, and in water channel, increases turbulence columns, while making cooling fluid flow through turbulence columns, forms turbulent flow, breaks through the moisture film on waterway wall, guarantees that cooling fluid fully contacts water channel surface, improves the radiating efficiency of housing.The present invention has the advantages that to improve product shock resistance and radiating efficiency.The present invention is mainly used in pure electric motor controller.

Embodiment
As shown in Figure 1.Motor controller structure of the present invention comprises shell 1 and is loaded on shielding iron plate 2, IGBT driver module and driver circuit plate 3, control circuit board 4, thin-film capacitor 5, current sensor 6 and noninductive Absorption Capacitance 7 in shell 1, busbar support 8, busbar 9 etc.Busbar support 8 other shell 1 housings are provided with the groove with noninductive Absorption Capacitance 7 form fit, and noninductive Absorption Capacitance 7 is positioned at this groove, and busbar support 8 is provided with the baffle plate that covers noninductive Absorption Capacitance.Busbar support 8 adopts plastic stent.Noninductive Absorption Capacitance 7 is fixed in the bottom groove of shell 1, the baffle plate of busbar support 8 covers above it, this structure can guarantee that noninductive Absorption Capacitance 7 is fixed in enclosure slot by firm, can stop it to shake up and down, and Surface Contact housing, guarantees its heat radiation, and it is effectively fixed, can effectively solve the problem of heat radiation deficiency and vibration damage.
As shown in Figure 2.Electric machine controller bottom radiating structure comprises shell 1, water channel 10, water inlet 11, delivery port 12 and turbulence columns 13.Water channel 10 is positioned at outer casing bottom, and water inlet 11 and delivery port 12 are located at respectively the two ends of water channel 10, and the turbulence columns 13 of projection is located in water channel 10.The center line setting that part turbulence columns 13 flows to along water channel 10, another part turbulence columns 13 is arranged on the sidewall of water channel 10.
Cooling procedure is: cooling fluid enters water channel 10 by water inlet 11, flows out finally by delivery port 12, takes away the heat of shell 1 housing.In the time that cooling fluid is flowed through turbulence columns 13, under the stopping of turbulence columns 13, formation turbulent flow, to 10 liang of side impact of water channel, can be broken through the moisture film on water channel 10 walls, makes cooling fluid fully contact housing inner lead surface, takes away the heat of housing, thereby improves radiating efficiency.
