1261104 九、發明說明： 【發明所屬之技術領域】 本發明涉及一種熱管測試方法，尤其涉及一種可以準 確快速地測試熱管導熱性能的熱管測試方法。 【先前技術】 隨著積體電路朝密集化、複雜化方向發展，其電子元 器件在工作時產生的熱量也隨之劇增，使元器件溫度升高 ，對元器件的正常工作產生影響。因此，必須安裝散熱裝 置以確保中央處理器或其他高溫晶片等發熱元器件在適當 的溫度下正常工作。 現有的散熱裝置已有利用熱管技術提高散熱能力，熱 管内部設有一密閉的中空腔體，該腔體内壁設有毛細組 織，該腔體是經過抽真空處理並灌注有少量工作流體（如 純水、酒精等）。熱管工作時工作流體在熱管的第一端吸 熱，在低壓下工作流體只需較低溫度（如攝氏50度）即可 沸騰成氣體，氣體運動到熱管的第二端放出熱量變為液 體，再在毛細組織的毛細力作用下回到第一端，其可將中 央處理器產生的熱量高效迅速地由熱管的第一端傳送到熱 管第二端的散熱鰭片上並散發到周圍的大氣中，使中央處 理器能正常工作。然而熱管在製造及運輸過程中的碰撞都 很容易產生肉眼難見的裂痕，導致腔體内的真空度下降而 大大降低其導熱能力，而這些裂痕難以用外觀觀察法來檢 測，因此只能逐一對熱管的導熱性能進行檢測從而確定其 是否合格。 而一般的熱管導熱性能的測試方法，是用手持熱管的 5 1261104 % -端’將其另-端浸人熱水内，過—段時間後憑手對 手胸的溫度感覺來判斷熱管的導熱性能是否能滿足要求 ，這種測試方法一次只能測試一根熱管，效 其主要憑藉人的主觀感覺來進行判斷，沒化指 果非常不準確。 知’ ^ ^ τ㈠八另激上述缺失之可改善，乃特潛心研 究亚配合學理之運用，終於提出—種設計合就有致改盖 上述缺失之本發明。 °1261104 IX. Description of the Invention: [Technical Field] The present invention relates to a heat pipe test method, and more particularly to a heat pipe test method capable of accurately and quickly testing the heat transfer performance of a heat pipe. [Prior Art] As the integrated circuit develops toward the intensive and complicated direction, the heat generated by the electronic components during operation also increases sharply, causing the temperature of the components to rise and affecting the normal operation of the components. Therefore, heat sinks must be installed to ensure that the heat-generating components such as the central processing unit or other high-temperature wafers are operating properly at the proper temperature. The existing heat dissipating device has been improved by heat pipe technology. The heat pipe has a closed hollow cavity inside, and the inner wall of the cavity is provided with capillary structure, and the cavity is vacuumed and filled with a small amount of working fluid (such as pure water). , alcohol, etc.). When the heat pipe is working, the working fluid absorbs heat at the first end of the heat pipe. At a low pressure, the working fluid only needs to be at a lower temperature (for example, 50 degrees Celsius) to boil into a gas, and the gas moves to the second end of the heat pipe to release heat into a liquid, and then Returning to the first end under the capillary force of the capillary structure, the heat generated by the central processing unit can be efficiently and quickly transferred from the first end of the heat pipe to the heat dissipation fin of the second end of the heat pipe and distributed to the surrounding atmosphere, so that The central processor works fine. However, the collision of heat pipes during manufacturing and transportation is prone to cracks that are difficult to see by the naked eye, resulting in a decrease in the degree of vacuum in the cavity and greatly reducing its thermal conductivity. These cracks are difficult to detect by visual observation, so they can only be used one by one. The thermal conductivity of the heat pipe is tested to determine if it is acceptable. The general test method for the thermal conductivity of the heat pipe is to use the 5 1261104%-end of the hand-held heat pipe to dip its other end into the hot water. After a period of time, the thermal conductivity of the heat pipe is judged by the temperature feeling of the hand chest. Whether it can meet the requirements, this test method can only test one heat pipe at a time, and the effect is mainly judged by the subjective feeling of the person, and the lack of indication is very inaccurate. Knowing that ' ^ ^ τ (1) eight can stimulate the above-mentioned lack of improvement, and is particularly interested in researching the application of sub-association theory, and finally proposed that the design has the invention of the above-mentioned missing. °

The screw 46 can be screwed in or out a certain distance to adjust the height of the pressure block 48. The wrench 50 is pulled downward to move the pressing rod 42 downward, and the pressing block 48 is pressed against the upper fixing plate 22 to fasten the heat pipe 7 between the upper and lower fixing plates (22, 24) to the fixing groove. 37 inside. The wrench 50 is pushed upward, and the pressing rod 42 can be pulled up to separate the lower fixing plate 24 by the elastic force of the upper fixing plate 22, so that the heat pipe 7 can be taken out from the fixing groove 37. @场 just tester 6 is a multi-channel temperature collector (such as nuac instrument) 'There are several temperature measuring terminals (not shown), these temperature measurement = sub- and the wire connected to the tester 6 62 passes through the small hole 34 and enters the fixing groove to be attached to the temperature measuring end 72 of the heat official 7. As described above, after the heat is conducted from the heating end 74 to the temperature measuring end 72 sandwiched between the upper and lower fixing plates (22, 24), the temperature of the temperature measuring end 72 rises after a period of time of 1 1261104. The temperature measuring end 72 of each heat pipe 7 of different serial number will be heated to a temperature, at which time the tester 6 transports the collected data to a computer (not shown) and displays it on a computer display (not shown). These materials also have a serial number corresponding to the serial number of the heat pipe 7. By using the serial number data, it can be known whether the thermal conductivity of the heat pipe 7 corresponding to a certain serial number meets the technical standard requirement, thereby judging whether a heat pipe 7 is a good product. When testing, please refer to the fourth figure. First, the lower fixing plate 24 is rotated upward to the first rotating position as shown in the second figure, and the heat pipes 7 are correspondingly installed into the card slots 36 of the lower fixing plate 24. Then, the wrench 50 of the centering device 40 is pulled downward to press the pressing rod 42 downward to press on the upper fixing plate 22, so that the upper and lower fixing plates (22, 24) clamp the heat pipe 7 therein. The temperature measuring terminals of the tester 6 will be closely attached to the temperature measuring end 72 of the heat pipe 7, and the heating ends 74 of the heat pipes 7 are suspended above the water surface of the hot water; then the lower fixing plate is rotated downward 24 to the second rotational position as shown in the first figure, so that the heating end 74 of the heat pipe 7 is immersed in the hot water of the constant temperature water tank 1 and starts timing; the heat pipes 7 are immersed in hot water for 30 seconds, and then passed the test. The temperature measuring terminal of the meter 6 measures the temperature data of the temperature measuring end 72 of the heat pipe 7 at this time, and sends the temperature data to the computer and displays it on the computer display.
