Description

Heat abstractor is airtight to run through structure

【Technical field】

A kind of heat abstractor is airtight to run through structure, espespecially a kind of to run through through the hollow cylinder with flanged structure with gas The heat abstractor of close chamber is simultaneously combined by the hollow cylinder and its flanged structure with the heat abstractor, and then provides a kind of radiating Device is airtight to run through structure.

【Background technology】

Existing electronic equipment improves with efficiency, wherein as processing signal and computing electronic component it is relative also compared with Preceding electronic component produces higher heat, and the general heat dissipation element being most often used includes heat pipe, radiator, temperature-uniforming plate etc. Element, and through heat dissipation is further increased after the electronic component contact of direct participant heating, prevent electronic component temperature mistake It is high and the facts such as burn.

Temperature-uniforming plate is a kind of face in a big way and the heat transfer application in face, and it is different from the point-to-point heat transfer side of heat pipe Formula, and used suitable for the more narrow part in space.

It is known that temperature-uniforming plate and a substrate are used in combination and passed through the heat that temperature-uniforming plate conducts the heater element on the substrate, Known technology mainly avoids the position of the chamber in temperature-uniforming plate, i.e., at the samming plate closing four outer couplings respectively formed with perforation simultaneously Wearing one has the copper post of internal screw thread, and substrate sets the position of copper post to open up an at least hole, then through one with respect to the temperature-uniforming plate The temperature-uniforming plate is fixed on the substrate by screw lock element by wearing the copper post and hole simultaneously in a manner of screw lock, but this fixation Mode is distant with the heater element because copper post is arranged at four couplings of the temperature-uniforming plate, and the temperature-uniforming plate is first with heating after fixing Part can not be brought into close contact, and then produce thermal chocking；To improve the foregoing problem that can not be brought into close contact, then dealer is straight by copper post The adjacent place for being correspondingly arranged in the position that the temperature-uniforming plate is sticked with heater element is connect, therefore the copper post directly has through temperature-uniforming plate The position of chamber, though tight ness rating prevents thermal chocking from producing when can increase assembling, the chamber of the temperature-uniforming plate is run through by the copper post Air-tightness is lost after destruction, its chamber interior no longer has vacuum state, and destroys the chamber because copper post runs through, then in it The flow path of the working fluid in portion is possible therefore interrupted, causes hot transfer efficiency to reduce, or even seriously also there may be let out Leakage, and then make the temperature-uniforming plate lose heat and pass effectiveness.

Furthermore U.S. Patent number 7066240 and 6302192 and a kind of equalizing plate structure 5 of 7,100,680 3 cases announcement, one Body 51 has the first flat board 511 and the second flat board 512 being separated from each other, and is provided with an outer protuberance 513 in the body periphery, So that the outer protuberance 513 is connected and forms a closed chamber 514；One groove 5111 is located on the first flat board 511 and remote The outer protuberance 513, and be connected with second flat board 512；One opening 52 penetrate first flat board 511 groove 5111 and Second flat board 512, and the groove 5111 includes an outer annular surface 5112, and with corresponding ring one of on the second flat board 512 Shape edge surface 5121 is connected so that the opening 52 is independently isolated from outside the body 51；The extension of one spacer portion 53 is contacted with the Between one flat board 511, the second flat board 512；One capillary fiber structure 54 is located at the closed chamber 514, though this structure by The design of groove 5111 and with supporting construction and with airtight effect, but because the setting of groove is made inside the temperature-uniforming plate The cavity space of steam-condensate circulating is greatly reduced, and the relative setting because of groove causes the contact area of temperature-uniforming plate and thermal source to diminish, Therefore not only hot transfer efficiency reduces contact area and also greatly reduced, and such a it is through structure and the position that can not confirm to run through It is no to keep airtight really.

Therefore known have the disadvantage that：

1. it is also easy to produce thermal chocking；

2. heat transfer area is reduced；

3. hot transfer efficiency reduces.

【The content of the invention】

Therefore, it is the shortcoming that solves above-mentioned known technology, the main purpose of the present invention, there is provided run through known to a kind of solution The heat abstractor for causing vacuum tight to leak with air-tight chamber runs through airtight construction.

For up to above-mentioned purpose, the present invention provides a kind of heat abstractor and runs through airtight construction, comprising：One first plate body, one Second plate body；

First plate body has one first side and one second side and one first hole, first hole through this first First and second side of plate body；Second plate body has one the 3rd side and one the 4th side and one second hole, the 3rd side with Foregoing first side is corresponding to be covered, and first and second plate body defines an airtight chamber jointly, second hole through this second Third and fourth side of plate body；Free end is in the hollow cylinder both ends and has one first flange and one second flange respectively, and The hollow cylinder wears first and second hole, and first and second flange be sticked respectively with second, four side and seal this First, the periphery of two holes.

First plate body has one first side and one second side and one first hole, first hole through this first First and second side of plate body；Second plate body has one the 3rd side and one the 4th side and a hollow cylinder, the 3rd side with Foregoing first side is corresponding to be covered, and first and second plate body defines an airtight chamber jointly, and the hollow cylinder is by the 3rd side Integrally extend to first plate body, and correspondingly wear foregoing first hole, the hollow cylinder is through one end of first hole Free end, and have one first flange, first flange, which is sticked, second side and seals the periphery of first hole.

It is can ensure that through the airtight structure that runs through of heat abstractor of the present invention when heat abstractor is carried out through the setting of structure The air-tightness of heat sink interior airtight chamber can still be possessed really.
