Lower end is hinged, and the middle part of fixed link 20 and cabinet 1 are rotatablely connected, and elastic component is connected between fixed link 20 and liquor box 3, this
Embodiment is tension spring；The upper end of connecting rod 21 and the left end of open and close door 22 are hinged；The middle part of open and close door 22 and the rotation of cabinet 1 connect
It connects.
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 liquor box 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 implementation between magnet 24 and cabinet 1
Example is tension spring.In order to make the adsorption effect between magnet 1 and magnet 24 more preferable, it is preferred that make the longest of telescopic rod 34 long
Spend 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 air bag
32 and magnet 1 gravity 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 sliding
Bar 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.
Do not use host when, thermovent 10 be open and close door 22 closing, reach dust-proof effect.When mainboard 6 is run, so that cabinet
Temperature in 1 increases, and 11 automatic running of radiator fan, operation method directlys adopt the prior art, and details are not described herein again；
Temperature in cabinet 1 increases the decomposing hydrogen dioxide solution so that in liquor box 3, generates water and oxygen, and in this process, liquor box
Liquid volume in 3 is gradually reduced.Oxygen enters in balloon 2, and balloon 2 is heaved, and the right end of fixed link 20 is swung up, connection
Bar 21 is swung, and open and close door 22 also follows counter-clockwise swing, to open thermovent 10；Radiator fan 11 is by the heat in cabinet 1
It sheds.And how much the size of thermovent 10 can do corresponding variation according to the heat in cabinet 1, i.e., when heat is more
It waits, decomposing hydrogen dioxide 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, the opening amplitude of thermovent 10 is bigger, and radiating efficiency is higher.
Meanwhile 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 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 the heat dissipation and cooling to mainboard 6 can be realized.
