Description
Technical field
The present invention relates to the working medium cooling system by contact of a kind of high-power electrical devices, belong to large power, electrically
Power device cooling system field.
Background technology
The many fingers of high-power electrical devices compound voltage driven type power semiconductor, as IGBT, IGCT,
IEGT, this kind of device drive power is little and saturation pressure reduces, and has input resistance height, switching speed fast, logical
State voltage is low, blocking voltage is high, bear the features such as electric current is big, it has also become current power electronic device development
Main flow, be widely applied to various alternating current generator, converter, Switching Power Supply, lighting circuit, traction pass
In the field power electronic circuit such as dynamic.
But when high power device works, the heat of generation can make chip temperature raise, if heat radiation is slowly,
So being possible to make chip temperature increase above allowed maximum junction temperature, the performance of device will be notable
Decline, and can not steady operation, thus cause device performance degradation or inefficacy, and study and show, greatly
Power device crash rate and its junction temperature index have direct relation, and its performance raises with junction temperature and reduces.Research
Data show, IGBT device operating temperature often raises 10 DEG C of crash rates increases by 1 times, draws additionally, overheated
Chip can be caused irreversible permanent damage by " electron transfer " phenomenon risen, and affects the chip life-span.With
Time along with the continuous increase of high power device capacity, heat dissipation is proposed the highest requirement.So
The basic task of high power device heat dissipation design is, according to thermodynamics ultimate principle, designs a low thermal resistance
Hot-fluid transmission channel, the heat making device send the most quickly and uniformly is transferred to radiating end, thus
Ensure when device runs, within its internal temperature remains at the junction temperature of permission.
Owing to power device needs insulation protection, current cooling technology many employings metal fin heat exchanger is strong
Make air-cooled, or cooling medium is dispelled the heat by intermediate structure mediate contact, by power with needing heat radiation power device
Device is fixed on heat dissipation cold plate surface, and heat transmission need by after heat-conducting silicone grease, conduction oil again
It is transferred to the flowing coolant within cold drawing, this traditional cooling dress through heat dissipation cold plate wall
Putting, because adding above-mentioned intermediary, thermal resistance increases and heat transfer efficiency is reduced, it is impossible in time will
Heat sheds, then be easier to cause high power heat build-up, makes electronic device junction temperature raise.
