Description

Heat sink device
Technical Field
The present invention relates to a heat dissipation device, and more particularly, to a simple heat dissipation device suitable for dissipating heat from a thyristor.
Background
At present, in an electric control and power distribution system, a thyristor switch (regulator) is generally used for controlling the on-off of loads such as a capacitor and the like, because the thyristor switch has large power consumption and high temperature, a radiator and a fan are required to be adopted for air cooling, at present, two heat dissipation devices are adopted for air cooling, one is a heat dissipation mode of only carrying out air cooling on a feather of the radiator, the heat dissipation device can not realize effective air cooling on a heat sink with the highest temperature, and the defect of low cooling speed exists; the other is a heat sink of the radiator in an air cooling heat dissipation mode, the fan is fixed on the radiator by a metal plate, and the defects of complex fan installation and high cost exist.
Disclosure of Invention
The utility model aims to solve the problems and realize a heat dissipation device with low cost and high heat dissipation speed.
The purpose of the utility model is achieved by the following technical scheme:
a heat dissipation device comprises a heat radiator and a fan, wherein the front side of a heat sink of the heat radiator is used for installing a thyristor, the fan is used for blowing air to the back side of the heat sink, the heat radiator comprises an installation feather used for installing and fixing (namely fixing an assembly consisting of the heat radiator, the fan and the thyristor), a fan feather used for fixing the fan and a plurality of sub-feathers, and the fan is used for air cooling the sub-feathers and the heat sink.
The installation vane and the fan vane are L-shaped.
A heat dissipation device, the height of the sub-feather is lower than that of the fan feather.
A heat dissipating device, the height of the sub-vane is lower than that of the installation vane.
The installation feather, the fan feather and the sub-feather are positioned on the reverse side of the heat sink.
The installation surface of the installation vane is higher than the height of the sub vane.
The mounting surface of the mounting feather is higher than an air channel formed by the fan for the sub-feather and the heat sink.
The fan fixing device has the advantages of reasonable design, simple fan fixing, low cost and good heat dissipation effect.
