SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a MOS fixing device for controller production usefulness, the fixed mode that the fastening screw was joined in marriage to the aluminium bar is adopted mostly to the fixed mode of MOS pipe on solving traditional electric vehicle controller that proposes in the above-mentioned background art makes the MOS pipe fix on the lateral wall of controller shell, this just leads to reserving a connection piece when producing the MOS pipe and is used for the installation, production cost has increased in the intangible, simultaneously in the use, the connection piece if warp can lead to the MOS pipe can not laminate completely on control shell's lateral wall, influence radiating problem.

In order to achieve the above object, the utility model provides a following technical scheme: a MOS fixing device for controller production comprises a fixing plate and two mounting plates, wherein a first blind groove is uniformly and vertically formed in the top of the front surface of the fixing plate, the length of the first blind groove is smaller than the width of the fixing plate, a second blind groove is uniformly and vertically formed in the bottom of the front surface of the fixing plate, the width of the second blind groove is the same as that of the first blind groove, the second blind groove corresponds to the first blind groove, the depth of the first blind groove is larger than that of the second blind groove, first radiating fins are uniformly arranged at the bottom of an inner cavity of the first blind groove, second radiating fins are uniformly arranged on the rear side wall of the inner cavity of the first blind groove, heat-conducting silica gel sheets are symmetrically arranged on the left side wall and the right side wall of the inner cavity of the first blind groove, third radiating fins are uniformly arranged on the rear side wall of the fixing plate, the two mounting plates are respectively welded, two the mounting panel body has all seted up the screw.

Preferably, the fixing plate is an aluminum fixing plate.

Preferably, a gap between two adjacent fins of the first heat dissipation fin corresponds to a gap between two adjacent fins of the second heat dissipation fin.

Compared with the prior art, the beneficial effects of the utility model are that: this scheme is through with the MOS intraductal first blind groove and the blind inslot of second that inlays on the fixed plate, fixes the fixed plate on controller shell lateral wall through the screw to replace traditional mounting means, effectively reduce the manufacturing cost of MOS pipe, the while can not appear because the connection piece warp and lead to the condition emergence that the MOS pipe can not laminate controller shell lateral wall, guarantees the radiating efficiency.
