Description
Technical field
The present invention relates to a kind of pick-up unit, be meant a kind of heat pipe performance inspection device especially.
Background technology
The essential structure of heat pipe is in the porous matter capillary structure layer of airtight pipe material inner wall lining with easy absorption working fluid, its central space then is empty state, and in the airtight tubing that vacuumizes, inject the working fluid that is equivalent to capillary structure layer pore total measurement (volume), can be divided into evaporator section, condensation segment and adiabatic section therebetween according to the relevant position that absorbs with the heat that sheds.
The principle of work of heat pipe is to make the liquid phase working fluid evaporation of containing in capillary structure layer when evaporator section absorbs heat, and vapour pressure is raise, and rapidly with the high enthalpy vapor stream that produces along the low condensation segment of passage migration pressure of the central authorities heat that sheds, condensation water then borrows the capillary force of capillary structure layer to return evaporator section absorption heat once again, so again and again by the circulation of absorption in the working fluid phase change process with a large amount of latent heat that shed, carry out successional Rapid Thermal transmission, and because liquid phase and the vapour phase of working fluid in said process coexist, thus heat pipe can under the situation that temperature almost remains unchanged, play the part of quick transmission heat the superconductor role and widely various field use.
Because the performance test of heat pipe mainly focuses on maximum heat biography amount (Qmax) and by evaporator section two parameters of temperature difference (Δ T) to condensation segment, therefore under a given heat delivered situation, can know its thermal resistance value by this temperature difference, and then the performance of assessment heat pipe; When given heat surpassed the maximum heat biography amount of heat pipe, owing to former normal hot biography mechanism is destroyed thermal resistance value is increased suddenly, so that the temperature of evaporator section also rose sharply thereupon.
A kind of properties of hot pipe detection method of the prior art is called immersion method, be that heat pipe evaporator section is inserted in the heated weighing apparatus geothermal liquid, after treating that heat pipe temperature is stable, for example thermopair, resistance temperature sensor (RTD) etc.s measure temperature difference between weighing apparatus geothermal liquid and the heat pipe condensation end to assess the performance of heat pipe by temperature sensor; Yet, above-mentioned prior art can't effective dose be measured the maximum heat biography amount and the thermal resistance of heat pipe, can only be according to this roughly fast a collection of heat pipe of verification of synchronization be confined to thermal response time (thermal response) under the set water bath condition, or preliminary screening goes out whether to have some heat pipe heat transmission function poor because of excessive temperature differentials showed in these heat pipes, it is how good or how poor to judge according to this that but wherein any Heat Transfer of Heat Pipe on Heat Pipe function has on earth, and therefore above-mentioned immersion method is difficult to accurately reflect the heat energy power of moving of heat pipe; In fact, no matter the yield quality of volume production heat pipe, common above-mentioned prior art only is used for the process that screens out (screening process) before the full detection of volume production, phase can be from the full heat pipe that detects of huge number needs, earlier dead pipe that will be commonly called as with immersion method fast or slow-witted pipe (for example: because of fluid injection undesired, seal impaired, vacuum tightness is undesired, reasons such as capillary structure oxidation, cause the heat pipe obviously can't normal operation person) screen out in advance, need subsequently to carry out the full amount detection of heat transfer property energy consuming time and that take a lot of work again in order to reduction, reach and reduce the purpose that detects cost at heat pipe by immersion method.
Another kind of the prior art heat pipe performance inspection device as shown in Figure 1, be to be the evaporator section 2a surface that thermal source is wrapped in heat pipe 2 with heating wire 1, be the heat sink condensation segment 2b surface that is sheathed on cooling jacket 3 simultaneously, adding all voltage and electric currents in heating wire 1 by modulation can provide heat pipe 2 one specified heating power, and remove this heating power by flow and the inlet water temperature of modulating cooling jacket 3 simultaneously, and so as to control heat pipe 2 in the stable operation temperature of adiabatic section 2c, the maximum heat biography amount of heat pipe 2 and then can learn to the mean temperature difference (MTD) of condensation segment 2b by each temperature sensor 4 of being located at heat pipe 2 surfaces by evaporator section 2a.
Yet the following many shortcomings of above-mentioned Fig. 1 and other existing heat pipe performance inspection device ubiquity all are unfavorable for the performance of accurate assessment heat pipe; Comprise:
(1) will reach the wall temperature that heat pipe and thermal source and heat sink driving fit thermo-contact also accurately measure simultaneously heat pipe evaporator section and condensation segment, present pick-up unit is difficult to take into account;
The more difficult effective control of above-mentioned requirements when (2) volume production is used many pick-up units;
The difficult accurately control of the effective length of evaporator section and condensation segment is to cause to assess another key factor that properties of hot pipe makes a variation when (3) examining entirely fast;
(4) measurement that reaches temperature of scattering and disappearing of heat all is vulnerable to the influence of external environment and produces variation;
(5) installation and removal are very loaded down with trivial details takes a lot of work, and makes known heat pipe performance inspection device be only applicable to laboratory scale a small amount of heat pipe test, fully can't be in response to the required detection requirement of volume production processing procedure;
(6) lack the elasticity that the heat transfer property in response to multi-form heat pipe can detect, consequently significantly increase the device and the human cost of volume production detection, even the delay in delivery phase.
With the complicated volume production process technique of present heat pipe, and need keep high-quality hot biography ability (high Q and low Δ T) and good fiduciary level, customer requirement is done steady state thermal transfer performance detection (the full detection) with total volume production heat pipe and has been belonged to normality; Heat pipe pick-up unit of the present invention promptly is to detect for the volume production properties of hot pipe is complete to design, and main operation requires to comprise: 1.) evaporator section at every heat pipe continues the evenly input one fixedly heat Qop less than Qmax on the surface area of an effective heated length of setting; 2.) continue the above-mentioned heat that is transmitted by evaporator section evenly to be left on the surface area of the efficiently radiates heat length of another setting with heating radiator at this heat pipe condenser section; 3.) keep a fixing operating temperature Top (the heat pipe Top of information industry is made as 60 ℃ usually) at the center surface of this heat pipe adiabatic section; 4.) under the heat pipe operating conditions of above-mentioned stable state, carry out the measurement of Δ T, and with Δ T whether 1 ℃ with interior as judge tested heat pipe by or the standard of eliminating; By above-mentioned typical detecting operation standard method, the requirement that can understand the full pick-up unit of volume production properties of hot pipe is very strict, and aforementioned by no means immersion method or prior art as shown in Figure 1 can reach; Except that the measurement of above-mentioned Δ T, heat pipe performance inspection device of the present invention also can accurately measure Qmax, thereby is applicable to that the volume production properties of hot pipe detects and be used to measure the demand of maximum heat biography amount entirely.
Be to cooperate the detection requirement of heat pipe volume production processing procedure, must be huge to quantity and heat pipe various informativeization carry out strict quality and check on; Promptly need to use simultaneously a large amount of detection boards owing to detect the volume production heat pipe of same form, and these detect the repeated use that board need be long-term and frequent; Therefore, except the measurement accuracy of board itself, more necessary assembling variation and operation variation to big amount detection machine platform gives strict keyholed back plate; Based on the good corrupt yield and the cost that will directly influence production of pick-up unit, the accuracy the when dealer certainly will face a large amount of detection, convenience, rapidity, consistance, reappearance, with multiple challenges such as reliability; In view of this, be necessary present heat pipe pick-up unit is done significantly to improve, thereby will assemble, operate and the modular design of assembly manufacturing is included in the lump, to meet the detection demand of heat pipe volume production processing procedure.
