Description

Thin plate type low-pressure thermosyphon plate driving by pressure gradient
Technical field
A thin plate type low-pressure thermosyphon plate driving by pressure gradient, espespecially a kind of capillary structure that can not must arrange can conduct heat, and has more the thin plate type low-pressure thermosyphon plate driving by pressure gradient of hot transfer efficiency.
Background technology
In recent years along with the progress of flourish, the process technique of electronic semi-conductor's industry, and under the trend of the market demand, electronic equipment gradually move towards compact kenel, but in the diminishing process of overall dimensions, function and operational capability are but growing on and on.The picture mobile computer that the output value is the highest in information industry and desktop PC are when actual operation; just there is multinomial electronic component to produce heat; the heat wherein being produced with central processor CPU (Central Processing Unit) is again maximum; now fin coordinates the radiator that fan formed to provide heat sinking function to play the part of the key player who protects CPU; make CPU maintain normal working temperature with the performance function that should have, therefore cpu heat is important spare part in information industry now.
So Water Cooling Technology starts to be used on personal computer widely in recent years, although water
Figure BSA00000207606900011
technology seems has saved bulky fin, but be that the heat of system endogenous pyrogen was collected in hydraulic fluid in fact, and then do the action of heat exchange by heat exchanger is unified with air, because length of pipe can change voluntarily, so the position of heat exchanger is elasticity comparatively also, also allows the design of heat exchanger (radiating fin) can not be subject to the restriction on space, a liquid flow but pumping of water-cooling system needs pushes the work forward, but also need a storage tank, so whole system still has pumping reliability issues, pipeline leakage problem ... etc., but because the heat of the heat generating component in personal computer constantly increases, so although water cooled heat radiating technology is not all roses, remain the optimal selection of heat management and control in the market, but, this is because the volume of personal computer is huger, and outside is also without limiting on space, but just different at mobile computer, mobile computer is at present more and more compact, just cannot make water at all
Figure BSA00000207606900012
heat dissipation technology, so remain at present, with heat pipe, do heat and shift, and then use radiating fin to do the action of heat exchange, in addition, also can only reduce the power consumption of CPU as far as possible.In view of this, industry is actively found the heat dissipation technology that heat flux is higher invariably, with in response to following one by one huge radiating requirements.
Known techniques also sees through heat pipe in addition, the radiating subassemblies such as temperature-uniforming plate are used as heat conducting component, and system manages wall moulding one sintered body in the inner thoroughly while manufacturing heat pipe and temperature-uniforming plate, as capillary structure, use, its main processing procedure system is first filled in metal (copper) or a powder in this inwall, again by its copper particle or powder densification compacting, finally send into and in sintering furnace, impose sintering processing, make this copper particle or powder form the capillary structure of porous character, make it to obtain capillary force by this sintered body, but because making the volume of this heat pipe and temperature-uniforming plate, this sintered body exists certain thickness also, and effectively slimming, described in another person, VC (Vapor chamber) is used the structures such as the core of sintering or grid or groove, and then generation capillary force phenomenon drives the steam/water circulating in heat pipe or VC (Vapor chamber), but the application manufacture in this structure is quite complicated, increase manufacturing cost, therefore very inappropriate.
Moreover the selection of steam core is a knowledge, select suitable steam core system quite important, this steam core need keep the flow velocity of condensate liquid and keep enough capillary pressure to overcome the impact of gravity.
Therefore the heat pipe of known techniques or VC (Vapor chamber) have following shortcoming:
1. processing inconvenience;
2. cannot realize slimming;
3. cost is higher;
4. expend man-hour.
Summary of the invention
For effectively solving above-mentioned problem, the main purpose of this creation, is to provide not need any capillary structure can drive working fluid transferring heat, and significantly reduces the thin plate type low-pressure thermosyphon plate driving by pressure gradient of manufacturing cost.
This creates another object, and being provides a kind of thin plate type low-pressure thermosyphon plate driving by pressure gradient with high-efficiency thermal transfer efficiency.
For reaching above-mentioned object, this creation system provides a kind of thin plate type low-pressure thermosyphon plate driving by pressure gradient, system comprises: a body, one plate body, this plate body correspondence covers aforementioned body, this body is provided with a heat affected zone near centre, these both sides, heat affected zone have a pressure accumulation district and a first flow group, Bing Gai pressure accumulation district connects a free zone, this free zone more connects one first condensing zone and one second condensing zone, this pressure accumulation district more connects one the 3rd condensing zone and one the 4th condensing zone, described first, between three condensing zones, there is one second runner group and be communicated with this first, three condensing zones, described second, four condensing zones there is one the 3rd runner group and be communicated with this second, four condensing zones, by suitable decompression design, produce low-pressure end, forming the required barometric gradient of steam/water circulating in the poor driving thermal siphon of driving pressure plate does not need any capillary structure can drive working fluid transferring heat, and significantly reduces manufacturing cost person.
