Embodiment
As shown in Figure 1, cooling pad of notebook computer of the present utility model mainly comprises main pad 11, secondary pad 13 and connecting conduit when implementing, place notebook computer on master's pad 11 during use, places computer mouse on the secondary pad 13, and promptly secondary pad 13 can be used as computer mouse mat.Described connecting conduit is divided into feed liquor conduit 12a and goes out two conduits of fluid catheter 12b.Connecting conduit 12 connects main pad 11 and secondary pad 13, constitutes fluid loop.Main pad 11 usefulness heat conductive rubbers make, and its upper surface has protruding pattern.The inside concrete structure of main pad 11 as shown in Figure 2, main pad 11 inner chambers are the return flow line shape, go into a retaining valve 21 and retaining valve 22 are respectively arranged respectively at the entrance and exit of return flow line and since the import and export setting retaining valve 21,22 arranged, so definite flow direction is arranged at the main liquid that fills up in 11.In addition, in main pad 11, also be provided with elastic bag 23.When the fluid pressure rising, air bag 23 is compressed, and when fluid pressure decline, air bag 23 expands.The structure of secondary pad 3 as shown in Figure 3 and Figure 4, secondary pad 13 is made by heat conductive rubber, liquid enters elasticity water pocket 33 by inlet 31, when elasticity water pocket 33 is extruded, then liquid flows out from exporting 32, when external force is removed, elasticity water pocket 33 restores to the original state automatically, and liquid is from 31 suctions that enter the mouth.Feed liquor conduit 12a one end connects retaining valve 21 other ends and connects outlet 32; Go out fluid catheter 12b one end and connect retaining valve 22, the other end connects inlet 31.
During making, the inner chamber full of liquid of main pad 11, secondary pad 13 and connecting conduit 12a, 12b.During use, then main pad 11 is placed under the notebook computer as the cooling pad of notebook computer, can certainly when making, will lead the part that pad 11 itself is made the notebook computer bottom enclosure.In the process of using, when the computer user is used pair pad 13 as mouse pad, palm can push elasticity water pocket 33, and the fluid pressure in elasticity water pocket 33 raises, by feed liquor conduit 12a conducting retaining valve 21, liquid comes out from elasticity water pocket 33, through feed liquor conduit 12a, enter main pad 11 inside, main pad 11 internal liquid pressure raise, elastic bag 23 pressurizeds shrink, and retaining valve 22 ends.During elasticity water pocket 33 stressed removing, elasticity water pocket 33 recovers its shape, and fluid pressure descends in the elasticity water pocket 33, and retaining valve 21 ends, retaining valve 22 conductings, and liquid flows to secondary pad 13 by retaining valve 22 through going out fluid catheter 12b in the main pad 11, and elastic bag 23 recovers shape.In above process, the liquid in the secondary pad 13 is owing to heated by notebook computer in main pad 11, and so its temperature is higher than environment temperature, liquid fills up 13 and dispels the heat to environment by secondary in pair pad 13.
During use, pair pad 13 can be placed on than main pad 11 eminences.When main pad 11 is heated by notebook computer, fluid temperature raises, volume increases, pressure rises, density lightens, retaining valve 22 conductings, liquid passes through retaining valve 22 from main pad 11, going out fluid catheter 12b flows in the secondary pad 13, liquid is by pair pad 13 heat that leaves, and temperature descends, and density rises, retaining valve 21 conductings, liquid in pair pad 13 is back in the main pad 11 by feed liquor conduit 12a, and device of the present utility model like this need not consumed power, and can to promote liquid circulation flow moving, circulates the purpose that reaches heat radiation thereby the heat energy that has promptly utilized the notebook that needs cooling to produce dexterously promotes heat eliminating medium.Make secondary pad 13 interior heat radiation water cavity bottom thickness fill up the thickness of 11 intracavity bottoms greater than the master during making, when using like this, also can play above-mentioned effect when being placed into desktop simultaneously,, use more convenient even the time spent generally need not painstakingly be placed on pair pad 13 than main pad 11 eminences.
During use, can also in main pad 11, secondary pad 13 and connecting conduit 12a, 12b, be full of and include Fe (NO
