Description
[technical field]
The present invention relates to a kind of measuring equipment, especially relate to a kind of heat-pipe measuring device.
[background technology]
In recent years, electronic technology develops rapidly, and the high frequency of electronic component, high speed and integrated circuit intensive and microminiaturized makes unit volume electronic component thermal value increase severely.Characteristics such as hot pipe technique is efficient with it, compactness and flexibility and reliability are fit to solve the heat dissipation problem that current electronic component is derived because of performance boost, become the main flow radiating mode of current electronic component gradually.
Heat pipe is a hollow sealing body, generally include shell, near the capillary wick (capillary structure) of inner wall of tube shell and be sealed in working fluid in the shell, the one end is evaporation ends (heating end), the other end is condensation end (colling end), can between evaporation ends and condensation end insulating segment be set according to application need.During work, heat pipe absorbs heat at evaporation ends by inner heat pipe phase change, and by steam flow heat is transported to the condensation end in stow away from heat district rapidly, reaches the purpose of a large amount of heat energy of quick transmission.Condensed liquid working fluid is transferred back evaporation ends by the capillary action of capillary wick.And then the repetition said process, thereby reach the heat sinking function of heat pipe.
Operate as normal when guaranteeing the heat pipe operation and give full play to its heat transfer property is tested at the performance parameter of heat pipe before using and is just become most important.The performance parameter of heat pipe comprises the heat pipe two ends temperature difference, heat pipe maximal heat transfer amount and heat pipe internal thermal resistance etc.Wherein, the maximum heat biography amount of heat pipe is to weigh one of adopting heat pipes for heat transfer performance parameter comparatively commonly used, and its influence factor comprises the selection of working fluid, the structure of capillary structure and the case material of heat pipe etc.The maximum heat biography amount of heat pipe is determining the maximum heat load that heat pipe can bear, and directly influence the occasion that this heat pipe can be suitable for, maximum heat load on affacting heat pipe is during greater than the maximum heat biography amount of heat pipe, will cause the working fluid excessive vaporization in the heat pipe, cause heat pipe to be in abnormal duty, cause reducing heat pipe serviceable life even it is damaged.Therefore, accurately measure the maximum heat biography amount of heat pipe and select suitable heat pipe in view of the above, be the heat pipe operate as normal and guarantee one of important prerequisite condition of the normal heat radiation of electronic package.
At present, comparatively Chang Yong a kind of device of measuring heat pipe maximum heat biography amount comprises a cooling device that is used to heat the heating arrangement of heat pipe and is used for the condensation heat pipe, wherein the heating arrangement end opposite heat tube that is located at heat pipe heats, and being located at the other end opposite heat tube of heat pipe, cools off cooling device, thereby make heat pipe be in normal running status, all evaporate by heat to the working fluid in the heat pipe that adds that improves heating arrangement then, this moment heating arrangement add the maximum heat biography amount that heat is heat pipe.
Above-mentioned heating arrangement (condensing unit) upper end is established a heat pipe and is inserted through hole and a plurality of duct in order to installation thermometer (or thermopair) that mouth, is used to insert heating rod (or feeding circulating cooling liquid body), these a plurality of ducts are linear, equidistant symmetric offset spread and insert mouthful both sides at heat pipe, wherein, insert mouthful both sides at this heat pipe and be provided with a plurality of grooves, thereby form a plurality of rubber-like thin-walleds.The heat pipe insertion mouth of this heating arrangement (condensing unit) to clamp heat pipe, requires the heat pipe caliber size strictness to match with an above-mentioned heat pipe insertion mouthful internal diameter by above-mentioned thin-walled elastic deformation.The heat pipe caliber is thick excessively, then cause inserting in addition insertion process in damage heat pipe, the heat pipe caliber is meticulous, then cause the heat pipe of heat pipe and heating arrangement (condensing unit) to insert between mouthful inwall and have too much air, bad, the thermal resistance increase of contact between said two devices, the heat of heating arrangement (heat pipe) can't be delivered on the heat pipe (cooling device) in time, rapidly, directly influences accuracy and reliability that the opposite heat tube heat transfer property measures.
In view of this, provide a kind of and have the heat-pipe measuring device of pin-point accuracy and reliability in fact for necessary.
[summary of the invention]
Below, will a kind of heat-pipe measuring device with pin-point accuracy and reliability be described with embodiment.
A kind of heat-pipe measuring device comprises a upper clip, lower clamping piece and a thermal interfacial material relative with this upper clip.Wherein, described upper clip has one first groove, described lower clamping piece has and second groove of described first groove fit with clamping one heat pipe to be measured, described upper clip or lower clamping piece are provided with at least one through hole that is used to insert heating rod or feeds cooling fluid, and described thermal interfacial material is positioned at described first groove and/or the second groove inside surface.
Compared with prior art, described heat-pipe measuring device is designed to two clamped-in style structures, need not the requirement that the heat pipe external diameter must insert the strict coupling of mouthful internal diameter with the heat pipe of heating arrangement (condensing unit) in the prior art, no matter heat pipe external diameter to be measured is bigger than normal or less than normal, can fill up slight void between described first groove and the second groove inwall and heat pipe contact interface to be measured by thermal interfacial material, thereby the thermal resistance between the contact interface of reduction heat-pipe measuring device and heat pipe, make heat-pipe measuring device have height-measuring accuracy and reliability, make this heat-pipe measuring device measure more practicability.And when described heat-pipe measuring device used, thermopair directly contacts to survey its temperature with heat pipe to be measured end, and was in order to the duct of a plurality of thermometers (or thermopair) to be installed, simple in structure in the omission prior art, is convenient to measure.
