Lid closes liquid outlet 31；The quantity of water distributor is two in the present embodiment, and two water distributors are symmetrically arranged at the two of liquor box 3
Side；That is two sealing covers 42 are combined to seal liquid outlet 31.The shape of sealing cover 42 can be according to liquid outlet 31
Shape adjusts, if liquid outlet 31 is rectangular, the shape of sealing cover 42 is preferably also cuboid；And if liquid outlet 31 is circle
Shape, then sealing cover 42 is preferably shaped to semicylinder.One end of aqueduct 5 can be connected with liquid outlet 31, aqueduct 5 it is another
One end is extended to outside babinet 1.As shown in Fig. 2, aqueduct 5 is preferably shaped to coil pipe, the surface of mainboard 6 is wrapped in, can be improved
To the cooling efficiency of mainboard 6.
Step 2, liquid feeding：A concentration of 95% hydrogen peroxide is filled it up with into liquor box 3.
Step 3, it is primary to radiate：While mainboard 6 is powered, start radiator fan 11, at this point, mechanism for opening/closing utilization is double
The oxygen that oxygen water decomposition generates automatically opens thermovent 10.Detailed process is：When mainboard 6 is run so that the temperature in babinet 1
Degree raising, 11 automatic running of radiator fan, operation method is directly using the prior art, and details are not described herein again；In babinet 1
Temperature increase the decomposing hydrogen dioxide solution so that in liquor box 3, generate water and oxygen, and in this process, the liquid in liquor box 3
Body volume is gradually reduced.Oxygen enters in balloon 2, and balloon 2 is heaved, and the right end of fixed link 20 is swung up, and connecting rod 21 is put
Dynamic, open and close door 22 rotates counterclockwise, so as to open thermovent 10；Radiator fan 11 sheds the heat in babinet 1.And thermovent
How much 10 size can do corresponding variation according to the heat in babinet 1, i.e., when heat is more, decomposing hydrogen dioxide solution compared with
Soon, oxygen generates rate and yield is also more, and 2 air-blowing higher of balloon, fixed link 20 is swung up bigger, correspondingly, opening and closing
Door 22 is also swung up bigger, and thermovent 10 opens amplitude bigger, radiating efficiency higher.
Step 4, secondary cooling：The water export that water distributor automatically generates decomposing hydrogen dioxide solution cools down mainboard 6.
Detailed process is：With the decomposition of hydrogen peroxide, the liquid volume in liquor box 3 is gradually reduced, and air bag 32 gradually moves down, magnet one
33 and then move down, until magnet 1 attracts the magnet 24 at both ends；Magnet 24 slides, and oscillating rod 40 is driven to swing, sliding bar
41 slide in and out, and sealing cover 42 slides in and out, and liquid outlet 31 is opened, and water in liquor box 3 is flowed into aqueduct 5, to mainboard 6 into
Row secondary cooling, better heat-radiation effect, water are finally expelled to outside babinet 1.The present embodiment is suitable for large-scale host heat dissipation, effect
Fruit is more preferable.
After water discharge, the oxygen in balloon 2 is fallen back in liquor box 3, and fixed link 20 resets under tension spring effect.In next time
When use, hydrogen peroxide need to be only added in from liquid-feeding tube 30 to liquor box 3 is filled, at this point, air bag 32 floats so that magnet 1
It is detached with magnet 24, magnet 1 and air bag 32 set back, you can convenient that mainboard 6 is radiated and cooled down next time.
