Description
[technical field]
The present invention is about heat abstractor, especially in regard to a kind of heat-pipe radiating apparatus that is applied in the electronic radiation device.
[background technology]
Electronic technology develops rapidly in recent years, the high frequency of electronic component, high speed and integrated circuit intensive and microminiaturized, make unit volume electronic component caloric value increase severely, therefore on electronic component, attach a heat abstractor, the heat that is produced when electronic component is worked conducts in the air, can steady running to guarantee electronic component.
The existing relevant heat abstractor structure that is used for assisting the electronic component distribute heat can be with reference to No. the 4th, 884,331, the United States Patent (USP) of bulletin on December 5th, 1989.This heat abstractor is convexly equipped with some radiating fins on base top surface, during work, this pedestal is attached to electronical elements surface heat is derived, and through radiating fin heat is shed again.But pedestal is a metal derby, even the strong metal materials of the capacity of heat transmission such as copper or aluminium also are difficult to satisfy the heat radiation requirement of present high frequency, high-speed electronic component gradually, therefore, heat conduction, the radiating efficiency of heat abstractor have much room for improvement.
In addition, on July 26th, 2000, the Chinese patent of bulletin disclosed a kind of heat abstractor that adopts heat pipe for thermal conductivity No. 99243628, see also Fig. 1, this heat abstractor 1 comprises a heat pipe 10, a plurality of radiating fins 11 and heat-conducting block 12, radiating fin 11 and heat-conducting block 12 are engaged in the two ends of heat pipe 10 respectively with sintering processing, the three engages and is one.During work, heat-conducting block 12 is attached on the electronic component (figure does not indicate), and the heat that electronic component distributes is given heat pipe 10 by heat-conducting block 12 conduction, and gives radiating fin 11 through superheater tube 10 conduction, is distributed in the air by radiating fin 11 again.The heat transfer efficiency of heat pipe 10 is than high hundreds of times of metallic copper, thereby can improve the radiating efficiency of this heat abstractor 1.
Also have in the prior art and adopt methods such as improving heat pipe work fluid to improve heat pipe for thermal conductivity efficient, shown in No. the 03146805.5th, Chinese patent, it adopts nanometer working fluid heat conduction nano particles such as (be in the conventional operation fluids such as pure water, ammoniacal liquor, methyl alcohol, acetone or heptane) suspended nano carbon balls to improve heat pipe for thermal conductivity efficient, adopts the heat pipe of this nanometer working fluid to be applied to heat-pipe radiating apparatus and will further improve the radiating efficiency of heat-pipe radiating apparatus.
But, normal sintering (as described in above-mentioned Chinese No. 99243628 patent), the welding methods such as (as described in No. 98202990 patents of China) of adopting in the prior art, combine heat pipe and radiating fin are permanent, though solve the compact problem of heat pipe and radiating fin to a certain extent, but because well-known heat pipe is aging easily, even adopt the heat pipe of nanometer working fluid, also can lose efficacy because nano-fluid the phenomenon of nano particle aggregate and precipitate occurs under long-time running, the general heat pipe life-span has only 1～2 year.Behind the heat pipe ageing failure, the radiating efficiency of heat-pipe radiating apparatus reduces greatly, in addition the entire heat dissipation device with scrap, thereby cause the serious wasting of resources.
Therefore, design that another heat pipe and radiating fin had not only combined closely but also easy-to-dismount heat-pipe radiating apparatus is very necessary.
[summary of the invention]
Below, will illustrate that a kind of heat pipe and radiating fin had not only combined closely but also easy-to-dismount heat-pipe radiating apparatus with a plurality of embodiment.
