Forced air cooling high -voltage board

The utility model discloses a forced air cooling high -voltage board, include: the high -voltage board casing, be provided with first fan composite set and second fan composite set in the high -voltage board casing, first fan composite set sets up the upper portion in the high -voltage board casing, second fan composite set sets up the lower part in the high -voltage board casing, first fan composite set and second fan composite set include the fan of two rows of continuous settings respectively, the air outlet of fan points to the below respectively. In this way, forced air cooling high -voltage board, the down -run of first fan composite set, the outside cold air of direct entry is lowered the temperature to the component, and the down -run of second fan composite set, it flows to form the air, takes away the inside heat of high -voltage board casing for every transformer all has gaseous high -speed mobilely on every side, reduces the mobile dead angle of air, carries high heat dissipation efficiency, and t
