Description
Technical field
The present invention relates to heat abstractor, espespecially a kind of heat abstractor saved manufacturing cost and reduce thermal resistance.
Background technology
Heat pipe is current a kind of termal conductor module be used in a large number on electronic equipment and electronic building brick, generally speaking, inside heat pipe is filled with good fluidity, heat of vaporization is high, boiling point is lower and the heat-conduction medium of stable chemical nature, such as water, ethanol and acetone etc., and the internal face of heat pipe is formed with most capillary structure in burr shape projection usually.
When reality uses, wherein one end of heat pipe is connected with the heat pipe seat be installed on electronic building brick as evaporation section, the other end of heat pipe is then supply most radiating fin installings as condensation segment, like this, when the evaporation section of heat pipe is heated, heat-conduction medium in heat pipe evaporator section will be vaporized and be absorbed a large amount of heat of vaporization, the temperature of heat pipe seat is reduced, then when this heat-conduction medium diffuses to heat pipe condenser section with steam state, this heat-conduction medium just can be attached on capillary structure and to be condensed into liquid state and to reflux towards heat pipe evaporator section, simultaneously also by waiting radiating fin to be distributed by a large amount of heat of liquefaction.
See Fig. 1, it is the three-dimensional exploded view of prior art heat abstractor, the radiator 31 that described existing heat abstractor 3 is made up of a multiple fin of tool and a pedestal 32 formed with at least one heat pipe 33, described radiator 31 has a heated parts 311 and a radiating part 312, this heated parts 311 is sticked with this pedestal 32, described heat pipe 33 one end is arranged between this heated parts 311 and this pedestal 32, and this heat pipe 33 other end is arranged in this radiating part 312, this heat abstractor 3 be through this pedestal 32 contact with a thermal source 4 and adsorb thermal source 4 produce and dislike heat, described heat conducts to radiator 31 and heat pipe 33 by this pedestal 32, and accelerate heat dissipation by the radiating part 312 that heat pipe 33 conducts to radiator 31.
In prior art, the purposes of the pedestal 32 of heat abstractor 3 is: one is be this radiator 31 of secure bond, and the radiating part 312 heat being directly conducted to radiator 31 fin outwards dispels the heat; Two is because this heat pipe 33 is that a cylindrical body cannot directly contact with thermal source 4, so pedestal 32 need be arranged and offer at least one groove 321 in this pedestal 32 side corresponding accommodating and combine with this radiator 31 for this heat pipe 33, afterwards again through this pedestal 32 with thermal source 4 Contact-sorption and heat conduction gives this radiator 31 and heat pipe 33.
When radiating subassembly and radiating subassembly combine owing to there being gap, so will thermal chocking be produced, therefore can solder bonds reduce, but too much its radiating efficiency is poor relatively in radiating subassembly combination, and when through many group radiating subassemblies in conjunction with common conductive heat time, radiating subassembly to each other need through assembly program then will expend comparatively farm labourer time, thus cause cost to improve.
In addition, pedestal and the volume of heat dissipation device combination military order heat abstractor own increase, and comparatively heavy, carrying and mobile in real be inconvenience, and due to volume comparatively greatly then when need be used in heat-dissipating space limited local time then cannot use; So prior art has its own shortcomings:
1. cost is higher;
2. expend and assemble man-hour;
3. heat-dissipating space smaller part is inapplicable;
4. heat pass and radiating efficiency low.
Summary of the invention
