Working solution in second housing separate chamber 111b is stopped because the heat in surperficial second district 202 of pyrotoxin 20 makes hydraulic fluid vaporization in it to move and by the carry heat in surperficial for pyrotoxin 20 second district 202 toward the first heat pipe chamber 123 toward the first heat pipe chamber 123 of the first heat pipe 12, hydraulic fluid after vaporization reverts back to liquid after blind end 121 place's condensation of the first heat pipe 12, then flows back to independently in housing cavity 111b along the capillary structure in the first heat pipe chamber 123.
Hydraulic fluid in 3rd housing separate chamber 111c is because the heat in the 3rd district 203, pyrotoxin 20 surface makes the vaporization of hydraulic fluid in it to move and by the carry heat in the 3rd district 203, pyrotoxin 20 surface toward the first heat pipe chamber 123 toward the first heat pipe chamber 123 of the first heat pipe 12, hydraulic fluid after vaporization reverts back to liquid after blind end 121 place's condensation of the first heat pipe 12, then flows back to independently in housing cavity 111c along the capillary structure in the first heat pipe chamber 123.
Hydraulic fluid in 4th housing separate chamber 111d is because the heat in the 4th district 204, pyrotoxin 20 surface makes the vaporization of hydraulic fluid in it to move and by the carry heat in the 4th district 201, pyrotoxin 20 surface toward the first heat pipe chamber 123 toward the first heat pipe chamber 123 of the first heat pipe 12, hydraulic fluid after vaporization reverts back to liquid after blind end 121 place's condensation of the first heat pipe 12, then flows back to independently in housing cavity 111d along the capillary structure in the first heat pipe chamber 123.
Four independently housing cavity 111a ~ 111d produce four independently steam-condensate circulating and heat trnasfer respectively, and do not interfere with each other each other, and the thermal temperature of each independently housing cavity 111a ~ 111d contact is different, the steam-condensate circulating of generation is different from the performance of heat trnasfer.
Above-mentionedly contact a pyrotoxin 20 as an example with housing 11, but in another is specifically implemented, on the position that pyrotoxin is intensive, housing 11 can be made to contact multiple pyrotoxin, wherein each separate chamber corresponds to a pyrotoxin, each separate chamber can also be played like this and produce independently steam-condensate circulating and heat trnasfer, and not disturb each other.
Be noted that especially, represent that above this housing cavity 111a ~ 111d is four and the volume of each housing cavity 111a ~ 111d is identical, but be not limited to this, as shown in Figs. 7-9, can be located in housing 11' according to use and radiating requirements and two independently housing cavity 311,312 or three independently housing cavity 411,412,413 or five independently housing cavity 511,512,513,514,515 are set, and volume can be identical or different.Moreover can according to the volume of each independently housing cavity, adjustment connects the quantity of heat pipe or the length of heat pipe, and what the volume of such as housing cavity was larger can connect two heat pipes; Or housing cavity connects two heat pipes and connects a heat pipe with a housing cavity, the heat pipe length now connecting two heat pipes is shorter compared to the length of a connection heat pipe.
In sum, the thermal diffusion of each separate chamber of the present invention with temperature-uniforming plate and the far-end heat transmission function of heat pipe, and produce multiple independently steam-condensate circulating and heat transfer processes after heated, the pyrotoxin for heat skewness provides best radiating effect.Structure of the present invention promotes cavity volume simultaneously, to increase the capacity holding hydraulic fluid, makes the maximum heat biography amount (QmaX) of heat pipe increase.
