Abstract
The utility model discloses a kind of controller for electric vehicle of excellent radiation performance, it comprises housing and is installed on the circuit board assembly in housing; Housing one sidewall is provided with air inlet, and another relative sidewall is provided with exhaust outlet; Air inlet is connected with air inducing flexible pipe, and the other end of air inducing flexible pipe is then connected with funnelform wind gathering head; The sidewall of housing has buckled a cloth wind box inside air inlet, and the wall of cloth wind box is provided with wind distributing hole; Exhaust outlet is connected with discharge hose, and the tail end of discharge hose is connected with rainhat.When car body advances, air-flow enters in housing through air inducing flexible pipe, then discharge through discharge hose, thus play the object taking away the heat that circuit board assembly produces, make to keep relatively low temperature in housing, ensure that the element in circuit board assembly normally works, extend the useful life that electric motor car controls; It omits the cooling mechanisms such as the fin of outside, and make controller for electric vehicle be more prone to processing and manufacturing, cost is cheaper.
Description
Technical field
The utility model relates to a kind of electronic control device, particularly relates to a kind of controller for electric vehicle of excellent radiation performance.
Background technology
Controller for electric vehicle, be used for controlling the startup, operation, advance and retreat, speed, stopping etc. of electric vehicle motor, simultaneously for other electronic device of electric motor car provides control, it is one of most important core component in electric motor car, and the quality of its performance will directly affect fail safe and the stability of electric motor car.Current controller for electric vehicle is generally primarily of circuit board assembly, housing is formed, multiple electronic component is integrated with in circuit board assembly, produce more heat in the course of the work, and in order to improve the water proofing property of controller for electric vehicle, housing adopts closed design usually, air in housing cannot carry out convection current, the heat that circuit board assembly is produced can not Quick diffusing, even if be provided with the fin for dispelling the heat at the outer wall of housing, but radiating effect is unsatisfactory, when circuit board assembly temperature is too high, break-off is even burnt, and circuit board assembly heat can not distribute in time and shortens its working life.In addition, although add at housing exterior walls the radiating efficiency that fin improves controller for electric vehicle to a certain extent, improve cost of manufacture and the difficulty of processing of housing, resultant effect is unsatisfactory.
Utility model content
For overcoming above-mentioned technical problem, it is simple that the utility model provides a kind of structure, perfect heat-dissipating, is conducive to reducing processing cart originally, increases the service life, and the controller for electric vehicle of the excellent radiation performance easily implemented.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of controller for electric vehicle of excellent radiation performance, comprises housing and is installed on the circuit board assembly in housing; The downside of its middle shell is provided with mounting flange, and upside is provided with the cover plate be bolted; The lead-in wire that described circuit board assembly is connected extends to outside through housing; Described housing one sidewall is provided with air inlet, and another relative sidewall is provided with exhaust outlet; Described air inlet is connected with air inducing flexible pipe, and the other end of described air inducing flexible pipe is then connected with funnelform wind gathering head; The sidewall of described housing has buckled a cloth wind box inside air inlet, and the wall of described cloth wind box is provided with the wind distributing hole flowing into housing cavity for uniform stream; Described exhaust outlet is connected with discharge hose, and the tail end of described discharge hose is connected with rainhat.
The utility model has following beneficial effect: during installation, wind gathering head is fixed on car body upwind position, and makes horn mouth forward, is vertically installed by rainhat, and wind gathering head and rainhat all should be in suitable height, avoids danger of flooding occurs.When car body advances, the air-flow that car body relative atmospheric produces enters in housing through air inducing flexible pipe, then discharge through discharge hose, thus play the object taking away the heat that circuit board assembly produces, make to keep relatively low temperature in housing, ensure that the element in circuit board assembly normally works, extend the useful life that electric motor car controls.Directly enter enclosure interior carry out heat loss through convection owing to which employs air-flow, thus can omit the cooling mechanisms such as the fin of outside, make controller for electric vehicle be more prone to processing and manufacturing, cost is cheaper.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1, mounting flange, 2, cloth wind box, 3, air inlet, 4, air inducing flexible pipe, 5, cover plate, 6, wind gathering head, 7, circuit board assembly, 8, bolt, 9, lead-in wire, 10, rainhat, 11, discharge hose, 12, exhaust outlet, 13, housing.
Embodiment
Shown in Fig. 1, a kind of controller for electric vehicle of excellent radiation performance disclosed in the utility model, it comprises housing 13 and is installed on the circuit board assembly 7 in housing 13; The downside of its middle shell 13 is provided with mounting flange 1, and upside is provided with by the fixing cover plate 5 of bolt 8; The lead-in wire 9 that described circuit board assembly 7 is connected extends to outside through housing 13; Described housing 13 1 sidewall is provided with air inlet 3, and another relative sidewall is provided with exhaust outlet 12; Described air inlet 3 is connected with air inducing flexible pipe 4, and the other end of described air inducing flexible pipe 4 is then connected with funnelform wind gathering 6, during installation, wind gathering 6 is fixed on the car body upwind position of electric motor car, and makes horn mouth forward; The sidewall of described housing 13 has buckled a cloth wind box 2 inside air inlet 3, and the wall of described cloth wind box 2 is provided with the wind distributing hole flowing into housing 13 inner chamber for uniform stream; Described exhaust outlet 12 is connected with discharge hose 11, and the tail end of described discharge hose 11 is connected with rainhat 10, and during installation, rainhat 10 is vertically installed, and prevents rainwater from falling in discharge hose 11; Described wind gathering 6 and rainhat 10 all should be in suitable height, avoid danger of flooding occurs.
When the car body of electric motor car advances, the air-flow that car body relative atmospheric produces enters in housing 13 through air inducing flexible pipe 4, then discharge through discharge hose 12, thus play the object taking away the heat that circuit board assembly 7 produces, make to keep relatively low temperature in housing 13, ensure that the element in circuit board assembly 7 normally works, extend the useful life that electric motor car controls.Directly enter housing 13 inside carry out heat loss through convection owing to which employs air-flow, thus can omit the cooling mechanisms such as the fin of housing 13 outside, make controller for electric vehicle be more prone to processing and manufacturing, cost is cheaper.
