Description
Technical field:
The utility model relates to a kind of pressure-driven loop-type thermal siphon device, refers to a kind of vapour-liquid circulation that does not need any capillary structure can increase loop-type thermal siphon structure especially, and the barometric gradient that reduces thermal resistance drives loop-type thermal siphon device.
Background technology:
In recent years along with the progress of the flourish and process technique of electronic semi-conductor's industry, and under the trend of the market demand, electronic equipment moves towards compact form gradually, but in the diminishing process of appearance and size, function and operational capability but are growing on and on.For example at family expenses or business computer and communication cabinet and family expenses or industrial heat exchanger/device during in actual operation; its inside just has multinomial electronic component to produce heat; wherein again to carry out the heat maximum that electron crystal or assembly were produced of computing; the radiator that this moment, fin cooperated fan to form provides heat sinking function promptly to play the part of the key player who protects electronic building brick, makes electronic building brick can maintain normal working temperature to bring into play due function.
And Water Cooling Technology its only begin to be used in widely on the personal computer, but by with and other are such as communication and family expenses or industrial heat exchanger/device, though seeming, Water Cooling Technology saves bulky fin, but be that hot piece with system's endogenous pyrogen focuses in the working fluid in fact, do the action of heat exchange then at and air unified by heat exchanger, because pipeline length can change voluntarily, so the position of heat exchanger is elasticity comparatively also, also allow the design of heat exchanger (radiating fin) can not be subjected to restriction on the space; The flowing of fluid but pump of water-cooling system needs pushes the work forward, but also need a storage tank, so whole system still has pump reliability issues, pipeline leakage problem etc., but because the evaporative component heat dissipation capacity in the personal computer constantly increases, so though the water-cooled heat dissipation technology is not all roses, remain one of optimal selection of heat management and control in the market, but, this is because the volume of personal computer is huger, and the outside restriction of also not having on the space; But it is just different on communication cabinet and family expenses or industrial heat exchanger/device, above-mentioned this device is at present all towards compact characteristic development, the limited heat dissipation technology that at all just can't use water-cooled of its overall space, use heat pipe or directly do transfer so remain at present with small-sized radiator, can't re-use radiating fin then and do the heat exchange action, in view of this, industry is actively sought the higher heat dissipation technology of heat flux invariably, to tackle following one by one huge radiating requirements.
In addition; conventional art also can see through heat pipe; radiating subassemblies such as temperature-uniforming plate use as hot transmitting assembly; and be by using as capillary structure in its inwall moulding one sintered body when making heat pipe and temperature-uniforming plate; its main processing procedure is earlier copper particle or powder to be filled in this inwall; again with its metal (copper) particle or powder densification compacting; send at last and impose sintering processing in the sintering furnace; make this copper particle or powder form the capillary structure of porous character; making it can be by the capillary force of this sintered body; but, make the volume of heat pipe and temperature-uniforming plate have certain thickness and effectively slimming also because of this sintered body.In addition, vaporium (Vapor Chamber) is to use the core or the structures such as network or groove of sintering, and then produces the carbonated drink circulation in capillary force phenomenon driving heat pipe or the vaporium (Vapor Chanber), but the manufacture of this structure quite bothers, increase manufacturing cost, so very improper.
Also can use traditional loop-type thermal siphon device to use in addition as heat conducting component, though should can reach heat biography effect by tradition loop-type thermal siphon device, but owing to mainly use capillary and weight-driven vapour, liquid circulation, because be vulnerable to the restriction of weight-driven, in addition the overall thermal resistance of loop-type thermal siphon device higher outside, the side tilt angle restriction of loop-type thermal siphon device is also higher, and restriction increased when design was used.
Therefore, all in the market personal computers and communication module all use the heat-pipe radiator solution, but radiating tube has heat load restriction, must use many and then cause the higher shortcoming of cost, and this heat radiation thermal resistance also not necessarily can reach the CPU thermal resistance requirement of dispelling the heat simultaneously.
Moreover, select suitable radiating core quite important, this radiating core must keep the flow velocity of condensate liquid and keep enough capillary pressure to overcome the influence of gravity.
In sum, there are following shortcoming in the heat pipe of conventional art or vaporium: (1) processing inconvenience; (2) can't realize slimming; (3) cost is higher; (4) expend man-hour.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of pressure-driven loop-type thermal siphon structure is provided that it can increase the vapour-liquid circulation of loop-type heat pipe, reduces the pressure-driven of thermal resistance; In addition, it need not to use the processing procedure of sintering capillary, can reduce production costs.
