Directional thermal siphon type heat column

Abstract

A directional thermal siphon type heat column comprises: a column body which is a sealed hollow cavity formed by a lid and a base and contains a liquid; and at least one partition element, being a hood plate fixed into the column body and extended obliquely towards the base and having a first channel formed on a side of the partition element opposite to the base and a second channel formed on one side of the partition element opposite to the lid, so as to avoid an opposite flushing occurred while the liquid inside the heat column is having a liquid/vapor phase change and prevent affecting the heat dissipation and circulation operation efficiency.

1 . A directional thermal siphon type heat column, comprising:
 a column body, being a sealed hollow cavity formed by a lid and a base, and provided for containing a liquid therein; and   a partition element, being a hood plate obliquely extended towards the partition element, and fixed into the column body, and the partition element comprising a first channel formed on a side of the partition element opposite to the base, and a second channel formed on another side of the partition element opposite to the lid.   
     
     
         2 . The directional thermal siphon type heat column according to  claim 1 , wherein the internal wall of the column body or the inner side of the lid has a capillary structure comprised of a metal crystal, a metal powder sintered lump, a copper mesh, a groove tube, or a mesh tube. 
     
     
         3 . The directional thermal siphon type heat column according to  claim 1 , further comprising an insulation gasket installed between the bottom periphery of the column body and the base for preventing a heat source from passing through the base or increasing the temperature of the column body. 
     
     
         4 . The directional thermal siphon type heat column according to  claim 1 , wherein the partition element further includes a through hole formed thereon for passing a middle tube. 
     
     
         5 . The directional thermal siphon type heat column according to  claim 4 , wherein the column body further includes a guide element fixed into the column body and disposed between the partition element and the base, and the guide element includes a top plate installed at an end of the guide element opposite to the lid for passing the middle tube, and the top plate includes a plurality of through holes, such that the guide element becomes a penetrating guide space. 
     
     
         6 . The directional thermal siphon type heat column according to  claim 5 , wherein the guide element includes an expanding circular portion and a guided ascending portion, both disposed opposite to the base. 
     
     
         7 . The directional thermal siphon type heat column according to  claim 6 , wherein the expanding circular portion is a circular plate extended obliquely towards the base, and the expanding circular portion has a bottom with a width slightly smaller than the internal diameter of the column body, and the expanding circular portion includes a plurality of separately protruded positioning plates and installed at the bottom periphery of the expanding circular portion, and the positioning plate is fixed onto the internal wall of the column body. 
     
     
         8 . The directional thermal siphon type heat column according to  claim 1 , wherein the partition element has a bottom with a width slightly smaller than the internal diameter of the column body, and the partition element includes a plurality of separately protruded positioning plates installed at the bottom periphery of the partition element, and fixed onto the internal wall of the column body. 
     
     
         9 . The directional thermal siphon type heat column according to  claim 5 , further comprising a circulation space defined between the middle tube an end and the lid, and another end of the middle tube being disposed at a bottom position inside the guided ascending portion, so that an appropriate distance from both ends of the middle tube to the base and lid respectively is maintained. 
     
     
         10 . The directional thermal siphon type heat column according to  claim 1 , wherein the column body includes an accessory heat sink installed on an external side of the column body, and the accessory heat sink includes a plurality of heat dissipating fins for dissipating heat from an external wall of the column body. 
     
     
         11 . The directional thermal siphon type heat column according to  claim 4 , wherein the middle tube is abutted and positioned between the base and the lid, and the middle tube includes a plurality of penetrating holes formed thereon. 
     
     
         12 . The directional thermal siphon type heat column according to  claim 11 , wherein the middle tube includes a heat dissipating element installed thereon, and the heat dissipating element includes a plurality of heat dissipating fins disposed around the heat dissipating element. 
     
     
         13 . The directional thermal siphon type heat column according to  claim 4 , wherein an appropriate distance from both ends of the middle tube to the base and the lid respectively is maintained, and the middle tube includes a plurality of heat dissipating fins installed under the partition element, and abutted against the internal wall of the column body for supporting the partition element to be fixed into the column body.
