Embodiment

See also Fig. 1, be the schematic diagram of heat abstractor in an embodiment of the present invention 1.This heat abstractor 1 can be used for being high temp objects, carries out radiating treatment as computer main board, CPU etc.This heat abstractor 1 comprises a loop assembly 10 and a Power Component 20, and this loop assembly 10 comprises a heat conduction case 101 and a return 102, and this heat conduction case 101 fully contacts with the high temp objects that needs heat radiation.This return 102 and this heat conduction case 101 are formed the loop of a closure, are filled with the liquid substance (not shown) in this loop, be used for and with high temp objects that heat conduction case 101 contact between carry out heat and conduct.In the present embodiment, this return 102 is arranged to helical form, thereby has increased area of dissipation in the volume that reduces heat abstractor 1, and this return 102 can be arranged to other shapes in other embodiments.This Power Component 20 is used to heat abstractor 1 that power is provided, and makes the liquid flow that is in the loop.Under the effect of this Power Component 20, this liquid substance that constantly absorbs the high temp objects heat circulates in the loop, and the heat that drives the liquid absorption distributes, thereby high temp objects is dispelled the heat.In the present embodiment, the liquid substance of filling in this loop is water, the contact surface that this heat conduction case 101 contacts with high temp objects arranges greatly as far as possible and contacts with the surface of high temp objects maximum, with the heat transfer area between liquid and the high temp objects in the expansion heat conduction case 101.For example, high temp objects is a strip object, and then the surface, place, long limit with this high temp objects contacts with the contact surface of heat conduction case 101, makes that heat transfer area is maximum.

See also Fig. 2 and Fig. 3.This heat conduction case 101 is provided with port one 011 and port one 012, liquid substance can flow into from a port of heat conduction case 101, flow out from another port, for example liquid substance self-loop pipeline 102 flows into heat conduction case 101 by port one 011, thereby and from port one 012 outflow heat conduction case 101 inflow returns 102.Inside at this heat conduction case 101 can also arrange the conduction trough (not shown), so that liquid substance flows according to the flow direction of conduction trough, thereby the liquid substance after the conduction of transference high temperature substrate body heat can flow out heat conduction case 101 as soon as possible, improve heat transfer efficiency, in the present embodiment, this thermal trough is " it " type structure.

This return 102 comprises pipeline 103 on, once pipeline 104 and a connecting tube 105, and should go up pipeline 103, pipeline 104 and connecting tube 105 comprise two ports respectively, inflow and outflow for liquid respectively down.The port of this heat conduction case 101, time pipeline 104, connecting tube 105 and last pipeline 103 joins end to end successively, constitutes an enclosed construction, and liquid does not circulate in this enclosed construction intermittently.

As shown in Figure 2, in the present embodiment, pipeline 103 port one 031 links to each other with the port one 011 of heat conduction case 101 by a downward interface conduit 1033 on this, and another port 1032 directly links to each other with a port one 052 of connecting tube 105.A port one 042 of this time pipeline 104 links to each other with the another port 1012 of heat conduction case 101, and another port 1041 links to each other with the another port 1051 of connecting tube 105.Should go up pipeline 103, following pipeline 104, connecting tube 105 and heat conduction case 101 and form the loop of a closure together, this liquid substance can flow in this loop.
