[ technical field ] A method for producing a semiconductor device
The utility model relates to an electric automobile's technical field, concretely relates to on-vehicle DC/DC converter.
[ background of the invention ]
The vehicle-mounted DC/DC converter is a power converter for converting high voltage electricity of an electric vehicle power battery into low voltage electricity of 12V, and generally has the ranges of 48V-90VDC, 90VDC-180VDC, 200VDC-450VDC and the like according to the voltage of different electric vehicle power batteries; in order to maximize the driving mileage of the electric vehicle, the DC/DC converter is required to have high conversion efficiency, small size, light weight and less heat generation.
[ Utility model ] content
In order to solve the above problems, an object of the present invention is to provide an on-vehicle DC/DC converter with light volume, good heat dissipation and high conversion efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a vehicle-mounted DC/DC converter comprises a shell and a substrate arranged in the shell, wherein the shell is provided with an output port and an input port; a power device is arranged on the substrate; the shell comprises a shell body with an opening on the side surface, a side plate and two end plates, wherein the shell body, the side plate and the end plates enclose a closed chamber; the base plate is arranged on the side wall of the shell, a gap exists between the base plate and the shell, the power device comprises a planar transformer, and an aluminum block is arranged in the gap between the bottom of a magnetic core of the planar transformer and the shell.
The utility model provides an on-vehicle DC/DC converter further sets up to: and the bottoms of the two end plates are provided with bent supporting legs.
The utility model provides an on-vehicle DC/DC converter further sets up to: and a plurality of heat dissipation strips are arranged on the outer surface of the shell.
The utility model provides an on-vehicle DC/DC converter further sets up to: the output port is arranged on one of the end plates, and the input port is arranged on the other end plate.
The utility model provides an on-vehicle DC/DC converter further sets up to: the material of the shell is AL 6063-T5.
Compared with the prior art, the utility model discloses following beneficial effect has: according to the vehicle-mounted DC/DC converter, the shell material is AL6063-T5, the heat conductivity coefficient is 201W/DEG C, and compared with ADC12 and 96W/DEG C materials of a heat conduction system adopted by most DC/DC converters on the market, the heat dissipation performance is doubled; the planar transformer is adopted, so that the size is small, the weight is light, and the conversion efficiency is high; an aluminum block is added between the bottom of the magnetic core of the planar transformer and the shell, so that the heat transmission distance between the planar transformer and the shell is greatly shortened, the heat dissipation is faster, and the temperature is lower; the whole body is installed in a side-standing mode, and the occupied area is smaller. The intelligent electric sightseeing bus can be applied to the fields of electric sightseeing buses, electric sweeping buses, unmanned patrol buses and the like of scenic spots.
