Abstract
The utility model relates to the technical field of electric vehicle fittings, and especially relates to a heat dissipation device of an electric vehicle controller in elastic fixation. The heat dissipation base of the heat dissipation device is equipped with a long elastic strip. The fixed edge of the long elastic strip is fixed on the upper top surface of the hollow cavity through connection pieces. An outer side of an elastic pressing edge is pressed elastically on power switch tubes in a row. That the power switch tubes are pressed on the installation plate of the hollow inner cavity is achieved. No installation of aluminum strips and no installation of power switch tubes one by one are needed. The heat dissipation device has characteristics of convenient and fast installation, simplified production technology and reduction of production cost. No bolts are needed to go through power switch tubes, and the problem that a heat dissipation base of a traditional heat dissipation device cannot meet high-voltage-resistant insulation resistance requirements because of the short creep distance between bolts and power switch tubes is solved. The heat dissipation path is shorter than that of a traditional heat dissipation base, heat can be dissipated fast, the overheating damage rate is reduced greatly, and the service life is prolonged.
Description
Technical field
The utility model relates to electric accessory motor technical field, refers in particular to a kind of resiliently mounted controller for electric vehicle heat abstractor.
Background technology
China was once bicycle big country, along with the raising of people's living standard, and the promotion of clean energy resource and the enhancing of environmental consciousness, electric motor car more and more welcomed by the people, electric motor car industry, during several years of Chinese market, has obtained development at full speed.Controller for electric vehicle is as one of electric motor car four large parts, and the assurance of its quality parameter plays an important role to the development of electric motor car.
In controller for electric vehicle, power switch pipe (metal-oxide-semiconductor) has small volume, and caloric value is large, the feature that heat generation density is high, most controllers are all provided with heat abstractor and distribute with the high heat that its work is produced, and make it not affect controller until the normal operation of car load because crossing cause thermal damage.
Heat abstractor includes a radiating seat, radiating seat arranges cavity conventionally, cavity inner bottom surface arranges PCB circuit board, one sidewall is arranged side by side some power switch pipes, described power switch pipe connection PCB circuit board, in the radiating seat of existing controller, is fixed on some power switch pipes separately on one aluminum strip by bolt, form power switch pipe in a row, and then aluminum strip is close on a madial wall of radiating seat cavity and carries out heat loss through conduction.Therefore in installation process, power switch pipe need be arranged on aluminum strip in turn, and then aluminum strip is connected and carries out heat loss through conduction with the sidewall of radiating seat.Therefore there is following drawback: bolt that need to be identical with power switch pipe quantity when 1, power switch pipe is locked on aluminum strip, and controller is managed even more according to different 6 pipes, 9 pipes, 12 pipes, 15 pipes, 18 of dividing of the quantity of power switch pipe, too much bolt is installed not only spended time, install not convenient, and the corresponding manufacturing cost that increased; 2, the bolt that power switch pipe connects will be by the thermal component of power switch pipe, and between bolt and power switch pipe, creepage distance is limited, can not meet the requirement of high pressure resistant insulation resistance; 3, heat dissipation path is power switch pipe---aluminum strip---mount pad, cause its heat dissipation path longer, thermal resistance strengthens, the heat that power switch pipe work produces can not distribute faster, in the time that the higher operating mode of ambient temperature is comparatively severe, power switch pipe can, because of the cause thermal damage of can not dispelling the heat in time, cause car load normally not move.
Utility model content
The utility model is the deficiency existing for current electric motor car heat abstractor, and provides the one overcoming the above problems resiliently mounted controller for electric vehicle heat abstractor.
For achieving the above object, the utility model adopts following technical scheme:
A kind of resiliently mounted controller for electric vehicle heat abstractor, described heat abstractor comprises that one arranges the radiating seat of cavity, the top of the inner bottom surface of described cavity arranges PCB circuit board, and a sidewall is arranged side by side some power switch pipes, and described power switch pipe is by pin connection PCB circuit board; In described cavity, arrange on the sidewall of power switch pipe mounting plane is set, power switch pipe is arranged side by side on mounting plane, the rectangular shell fragment of one " factory " font is set in the cavity of described radiating seat, rectangular shell fragment arranges a fixed edge, fixed edge is fixed on the upper end face of cavity by connector, fixed edge connects a downward limit of suppressing, described in suppress limit outer elastic and overlay on power switch pipe in a row.
Preferably, the periphery of described radiating seat arranges fin.
Preferably, described connector is the above bolts of two of arranged outside that are arranged on the upper end face of cavity, the be spirally connected fixed edge of rectangular shell fragment of described bolt.
Preferably, the retainer plate that the end setting of described fixed edge is bent to form, arranges arc holddown groove in described upper end face, and described retainer plate is plugged in arc holddown groove.
Preferably, described in suppress edge tail and some openings are set form and suppress bar, described in suppress bar and overlay on power switch pipe.
Preferably, the end that suppresses limit described in arranges overlaying of arc and bends position.
Preferably, between described mounting plane and power switch pipe, heat insulating lamella is set.
The beneficial effects of the utility model are, resiliently mounted controller for electric vehicle heat abstractor of the present utility model, the rectangular shell fragment of one " factory " font is set in the cavity of its radiating seat, rectangular shell fragment arranges a fixed edge, fixed edge is fixed on the upper end face of cavity by connector, connect close and firm, difficult drop-off, safeguard work performance; Fixed edge connects a downward limit of suppressing, suppressing limit outer elastic overlays on power switch pipe in a row, thereby realize on the mounting plane that power switch pipe rides over hollow cavity, realize power switch pipe and ride over the object on radiating seat, only need fixed edge be fixed on by connector to the upper end face of cavity by connector, and without aluminum strip and installation power switching tube are in turn installed, have quick and easy for installation, simplify production technology, reduced the feature of production cost; In addition, when constant power switching tube, the limit of suppressing by rectangular shell fragment is realized power switch pipe and is overlayed the inwall at radiating seat, by power switch pipe, avoid the radiating seat of traditional heat-dissipating device because creepage distance between bolt and power switch pipe is very near, can not meet the problem generation that high pressure resistant insulation resistance requires completely without bolt; Again, power switch pipe rides over radiating seat and directly dispels the heat and save this heat dissipation path of aluminum strip than existing controller, and the radiating seat that heat dissipation path is more traditional is shorter, and heat can be distributed faster, greatly reduces its overheated spoilage, strengthens its useful life.
