7. The bitmap processing apparatus of claim 1, wherein the stepper motor is configured to control the opening and closing of the air holes.

8. A method of dissipating heat, the method comprising: monitoring whether current calorific capacity of device that generates heat exceeds predetermined heat dissipation capacity, if, then apply through the subsides in the capillary radiating piece absorption of device that generates heat by the heat that the device that generates heat distributed, wherein, capillary radiating piece absorbs the radiating liquid from the liquid storage tank that it connects, works as the radiating liquid flows through during the capillary radiating piece the gaseous state is converted into by liquid under the thermal effect, carries thermal gaseous radiating liquid by passing to the gas conduit of capillary radiating piece top, through the gas conduit will gaseous radiating liquid conduction to with the communicating gas pocket of exterior space, carry thermal gaseous radiating liquid by the gas pocket to exterior space gives off.

9. The method for dissipating heat according to claim 8, wherein the remaining amount of the heat dissipating fluid is monitored by a hydraulic sensor disposed at a bottom of the reservoir, and the heat dissipating fluid is replenished when opened and prevented from running off when closed by a rear cover disposed at a top of the reservoir.

10. The method for dissipating heat according to claim 8, wherein the opening and closing of the air hole is controlled by a stepping motor connected to the air hole.
