Body 1 is rotatablely connected.Do not use host when, thermovent 10 be open and close door 22 closing, reach dust-proof effect.
The top of liquor box 3 is equipped with filling opening, and filling opening is connected to a liquid-feeding tube 30, and liquid-feeding tube 30 is L-shaped, and liquid-feeding tube 30
Upper end extend to outside cabinet 1.The bottom of liquor box 3 is equipped with liquid outlet 31, is placed with air bag 32 in liquor box 3, air bag 32
There are a distance in the two sides of both ends to bath foam case 3, and the top of air bag 32 is bonded with magnet 1, the center of magnet 1 with it is molten
It is fixedly connected with telescopic rod 34 between the top of liquid case 3, helps to make air bag 32 more stable with the location free procedure of hydrogen peroxide,
It is not that air bag 32 is allowed arbitrarily to shake on liquid level.
Water distributor includes magnet 24, oscillating rod 40, sliding bar 41, sealing cover 42 and aqueduct 5.Magnet 24 and solution
Case 3 is slidably connected, then concrete mode can allow magnet 24 and the sliding rail to connect a sliding rail between liquor box 3 and cabinet 1
It is slidably connected；And the right end of magnet 24 and liquor box 3 are tightly connected.Distance and liquor box 3 of the magnet 24 to 3 top of liquor box
Height ratio be 2/5, be suitable in this way decomposing hydrogen dioxide solution be water volume change, i.e., when the hydrogen peroxide in liquor box 3 all
After being decomposed into water, magnet 24 can be attracted by magnet 1, and be connected with return unit, this reality between magnet 24 and cabinet 1
Applying example is tension spring.In order to make the adsorption effect between magnet 1 and magnet 24 more preferable, it is preferred that allow the longest of telescopic rod 34
Length being equidistant to 3 top of liquor box with magnet 24；In this way, after magnet 1 attracts magnet 24, it will not be because of gas
The gravity of capsule 32 and magnet 1 and be separated from each other.The upper end of oscillating rod 40 and magnet 24 are hinged, the lower end of oscillating rod 40 and cunning
Lever 41 is hinged, and the middle part of oscillating rod 40 and cabinet 1 are rotatablely connected, to form lever；Sliding bar 41 and the sliding of cabinet 1 connect
It connects, and the right end of sliding bar 41 and sealing cover 42 weld, the top of sealing cover 42 is connect with the basal sliding of liquor box 3, and energy
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 be it 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 to liquid outlet 31, aqueduct 5 it is another
One end extends to outside cabinet 1.As shown in Fig. 2, aqueduct 5 is preferably shaped to coil pipe, it is wrapped in the surface of mainboard 6, can be improved
To the cooling efficiency of mainboard 6.
Liquid feeding: step 2 fills it up with the hydrogen peroxide that dense upper degree is 95% into liquor box 3.
Step 3, it is primary to radiate: while mainboard 6 is powered, to start radiator fan 11, at this point, mechanism for opening/closing is using double
The oxygen that oxygen water decomposition generates automatically opens thermovent 10.There is detailed process are as follows: when mainboard 6 is run, so that in cabinet 1
Temperature increases, and 11 automatic running of radiator fan, operation method directlys adopt the prior art, and details are not described herein again；Cabinet 1
Interior temperature increases the decomposing hydrogen dioxide solution so that in liquor box 3, water and oxygen is generated, and in this process, in liquor box 3
Liquid 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, connecting rod 21
It swings, open and close door 22 is rotated against gesture hour hands, to open thermovent 10, radiator fan 11 sheds the heat in cabinet 1.And it dissipates
How much the size of hot mouth 10 can do corresponding variation according to the heat in cabinet 1, i.e., when heat is more, dioxygen moisture
Solution is very fast, and oxygen generates rate and yield is also more, and 2 air-blowing of balloon is higher, and fixed link 20 is swung up more greatly, correspondingly,
Open and close door 22 is also swung up more greatly, and the opening amplitude of thermovent 10 is bigger, and radiating efficiency is higher.
Step 4, secondary cooling: water distributor automatically cools down the water export that decomposing hydrogen dioxide solution generates to mainboard 6.
There is detailed process are as follows: 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, and until magnet 1 attracts the magnet 24 at both ends, magnet 24 is slided, and drives oscillating rod 40 to swing, sliding
Bar 41 slides in and out, and sealing cover 42 slides in and out, and liquid outlet 31 is opened, and the water in liquor box 3 flows into aqueduct 5, to mainboard 6
Secondary cooling, better heat-radiation effect are carried out, water is finally expelled to outside cabinet 1.The present embodiment suitable for large-scale host heat dissipation,
Effect 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 only be added from liquid-feeding tube 30 to liquor box 3 is filled, at this point, air bag 32 floats, so that magnet 1
It is separated with magnet 24, magnet 1 and air bag 32 set back, and can conveniently mainboard 6 be radiated and be cooled down next time.
Embodiment 2
The present embodiment the difference from embodiment 1 is that:
In step 1: the volume of liquor box 3 is 10L；As shown in figure 3, the quantity of mechanism for opening/closing is two, and two opening and closings
