Abstract
The utility model discloses a cooling structure of a controller. The cooling structure comprises a main radiator and power devices located on the main radiator and is characterized in that a soft insulated heat sink with high thermal conductivity is arranged between the power devices and the main radiator, and the power device is sequentially pressed on the heat sink and the main radiator by a fixing part. The fixing part includes a screw, which passes through a housing to press a depression bar on the upper surfaces of the power devices. The cooling structure comprises more than two power devices and the heat sink is in an integrated structure. According to the utility model, the power devices have good cooling effect when running under the condition of higher frequency and larger current due to the adoption of the heat sink made of soft insulated silicone rubber material with high thermal conductivity, thereby improving the operation reliability of the controller.
Description
Technical field
The utility model relates to a kind of radiator structure.
Background technology
In recent years, more and more important role is played the part of in electric motor car in daily life, in the circuit of controller for electric vehicle, some power devices that can generate heat when operation is arranged, and these power devices mostly are installed on the same main radiator.Because between the power device, all be to need isolation between power device and the main radiator, namely master's radiator can not be charged when operation for power device, so the insulating material of buffer action must have been arranged between power device and main radiator.When under upper frequency and larger current condition, moving, the power device temperature rise is fast and high, this radiator structure is because contacting between power device and the radiator is rigid contact, effectively contact area is little, heat-conducting area namely is little, because the insulating material between power device and the main radiator has certain thermal resistance, shows inefficient shortcoming again, heat radiation to power device has very adverse influence, and power device is often because of bad damage of dispelling the heat.
The utility model content
The purpose of this utility model provides a kind of controller radiator structure of perfect heat-dissipating.
To achieve these goals, by the following technical solutions: a kind of controller radiator structure, comprise main radiator and the power device that is positioned on the main radiator, it is characterized in that: also be provided with soft, fin insulation and that have high thermal conductivity coefficient between described power device and the main radiator, the power device fixture presses successively on fin and main radiator.
Described fixture comprises screw, and screw passes shell press strip is pressed upper surface in power device.
Described power device is more than two, and fin is the integral type structure.
The utility model is by the application of fin soft, that silastic material insulation, high thermal conductivity coefficient is made, when power device is moved under higher frequency and larger current condition, have good radiating effect, thereby improved the controller reliability of operation.
Description of drawings
Fig. 1 structural representation of the present utility model.
Among the figure, 1 is that main radiator, 2 is that fin, 3 is that power device, 4 is that press strip, 5 is that screw, 6 is wiring board.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, between the power device 3 and main radiator 1 of needs heat radiation, install corresponding fin 2 additional, the insulating surfaces of power device installs press strip 4 additional, uses screw 5 assemblings to compress.That fin 2 adopts is soft, silastic material insulation, high thermal conductivity coefficient is made, that directly installation is close in contact between power device 3 and this fin 2, need not other material isolation between the two, also be directly to contact to be close to installation between fin 2 and the main radiator 1, also need not other material isolation between the two, fin between each power device does not need mutual partition yet, is the fin of an integral body.
Its good effect of this radiator structure is: have fin soft, that silastic material insulation, high thermal conductivity coefficient is made, because the soft speciality of this fin, between power device and the fin, can obtain maximum effective contact area between fin and the main radiator, namely obtain maximum heat-conducting area.Because the speciality of this fin insulation, between power device 3 and the fin 2, do not need other material to isolate between fin and the main radiator, fin 2 is the structure of an integral body, and it is very convenient to install, and has obtained minimum thermal resistance.The heat that power device produces because this fin has the speciality of high thermal conductivity coefficient, itself has certain hot melt quantity again, so can conduct rapidly to main radiator 1 by this fin when operation.When this just makes power device move under upper frequency and larger current condition, can not damage because heat radiation is bad, thereby improve the controller reliability of operation.
This kind controller radiator structure except applicable controller for electric vehicle, also is applicable to the controller heat radiation of other motor vehicle with constructed requirement or ship.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.
