Therefore, when the thermometer displays that the surface temperature of the main board 19 is too high, in order to further avoid the temperature rise of the display card to cause the temperature rise in the case 1 to affect the work of other parts (especially, when the temperature of the CPU is too high, the frequency reduction is caused), the mounting rack 24 can be driven to drive the display card to move outwards, and meanwhile, the mounting rack 24 pushes the telescopic rod 2 and the movable plate 3 to extend out. In the process, due to the sliding of the mounting frame 24, the rotating plate 25 is driven to rotate towards the movable plate 3 continuously, so that the movable plate tends to be in a horizontal state, and the radiator can blow and fan heat to the display card. Like this, just can generate heat serious back again, release quick-witted case 1 with the display card, then carry out solitary heat dissipation to the display card through independent radiator to upwards blow out quick-witted case 1 with the heat, increase the fan heat effect, reduce the influence of display card to other parts.
