High efficiency heat dissipation display card

The utility model discloses a high efficiency heat dissipation display card, comprising a fixed frame, the inside bottom of fixed frame is equipped with the cooling sap cavity, the top of fixed frameis equipped with the recess, the fixed frame inside of recess bottom is equipped with 2 radiating grooves, the internally mounted of radiating groove has first heat dissipation fan. This device is convenient for dismantle the change to the display card, high durability and convenient use, and carry out heat conduction through the radiating block with display card bottom contact, dispel the heat tothe radiating block at by freezing liquid, first heat dissipation is simultaneously gone into the outside air between radiating block and the cooling coil from L type piping, it moves to carry upperair current, and the radiating effect, and air admission L type when pipe coolant liquid certain degree has reduced the temperature of air, thereby the radiating efficiency has been improved greatly,and a plurality of heat abso
