Description
[technical field]
The utility model relates to a kind of heat abstractor, is meant a kind of effectively heat-pipe radiating apparatus of cooling electronic components especially.
[background technology]
Along with electronic industry constantly develops, electronic component (particularly central processing unit) speed of service and overall performance are in continuous lifting.Yet its caloric value also increases thereupon, and volume is more and more littler on the other hand, and heating is also just more concentrated, makes industry use the heat abstractor of metal solid heat transfer can't satisfy the radiating requirements of high-end electronic component merely.
For this reason, industry is brought into use the heat abstractor that has heat pipe.Heat pipe is mainly to be made up of capillary structure that is provided with on vacuum-packed tubular shell, its inwall (as powder sintered thing, groove structure, screen net structure etc.) and interior hydraulic fluid of packing in right amount (as water, alcohol, fluorine Lyons, acetone etc.) thereof.Heat pipe be carry out after being heated by hydraulic fluid that liquid vapour two phase change absorb, release heat to be to reach the heat transfer purpose, owing to the Heat Transfer of Heat Pipe on Heat Pipe non-directional and heat transfer distances is long is used widely.
The TaiWan, China patent has disclosed a kind of heat abstractor that uses heat pipe for M245465 number, it comprises that one is provided with pedestal, several " L " font heat pipes and some radiating fins that equidistantly piles up of several grooves, wherein the horizontal component of this each heat pipe is incorporated on this pedestal, and its upwardly extending vertical component passes radiating fin.This pedestal by heat pipe with the heat transferred that absorbed to these some radiating fins, and the heat on the radiating fin distributes in surrounding air by its surface.But, the parallel groove on the pedestal that only depends on of several heat pipe horizontal components of above-mentioned heat abstractor fixes, these horizontal components bearing of trend on pedestal is single, vacillate now to the left, now to the right easily distortion or get loose of heat abstractor when producing vibrations by fan or other reason, make to engage badly between heat pipe and pedestal, the radiating fin, influence the radiating effect of heat abstractor; In addition, the some radiating fins of vertical component socket of several heat pipes are equivalent to by heat pipe these radiating fins with constant weight be hung aloft, and the heat pipe support load is too big, and easy opposite heat tube causes damage when producing vibrations; Also have, because the restriction of machining, heat pipe is difficult to vertical bending usually, its bending part generally is rounding top and bottom pattern, so some radiating fins of above-mentioned heat abstractor can't overlap the bending part of receiving its circular arc when being sheathed on this " L " font heat pipe, thereby have a spacing not utilize between radiating fin and the pedestal.
[summary of the invention]
The purpose of this utility model is to provide a kind of radiating efficiency height and the more firm heat-pipe radiating apparatus of structure.
The purpose of this utility model is achieved through the following technical solutions:
Heat-pipe radiating apparatus of the present utility model comprises a pedestal, at least one first heat pipe and at least one second heat pipe, this two heat pipe all has the evaporation part that is connected with pedestal and reaches by the evaporation part end to the condensation part of extending away from the pedestal direction, some first stacked radiating fins mutually are arranged in the condensation part of this two heat pipe, the evaporation part of this first heat pipe and second heat pipe is arranged in a crossed manner on pedestal, and pedestal is provided with most second radiating fins towards the surface of first radiating fin.
The utility model is compared with prior art has following advantage: because first heat pipe and second heat pipe of heat abstractor are arranged in a crossed manner, prevent that effectively heat abstractor from producing wiggly possibility, makes the structure of heat abstractor firm; In addition, first heat pipe and second heat pipe are arranged in a crossed manner mutually, its each condensation part can be transmitted heat by pedestal to radiating fin from different directions, make heat can be sent to each position of radiating fin uniformly, and pedestal is provided with most second radiating fins and strengthens heat radiation to the first radiating fin surface, effectively utilizes the spacing between the pedestal and first radiating fin.
The further improvement of heat-pipe radiating apparatus of the present utility model is, the said base bottom surface also is provided with a base, this base top surface is provided with for establishing the groove of the first heat pipe evaporation part with the common folder of pedestal, and wherein at least one first heat pipe evaporation part is located between this pedestal and the base.Because the condensation part that pedestal and base pinch are established first heat pipe makes the fixing more firm of the heat pipe of winning, and helps improving the structure steadiness of entire heat dissipation device.
The further improvement of heat-pipe radiating apparatus of the present utility model is that above-mentioned first radiating fin and second radiating fin lean mutually.Because these some first radiating fins lean on second radiating fin, further alleviate the load that heat pipe supports these some first radiating fins, make heat pipe more stable with contacting of pedestal, radiating fin, and ensure not sensitive for damages of heat pipe.
With reference to the accompanying drawings, the utility model will be further described in conjunction with the embodiments.
