Description
本發明係涉及一種熱管構造及其製法;特別是指一種能夠控制毛細組織燒結位置且兼具擴增蒸氣流道空間、更利於管壁曲變加工、更易於製造成型及增進工作液汽化效率等諸多實用進步性之創新設計者。The invention relates to a heat pipe structure and a preparation method thereof; in particular to a method capable of controlling the sintering position of the capillary structure and having the space of augmenting the vapor flow path, facilitating the bending process of the pipe wall, making it easier to manufacture and improving the vaporization efficiency of the working fluid, etc. Many practical and progressive innovative designers.
按,習知熱管結構設計上,為達到較佳的熱傳導效率,係導入複合毛細組織結構型態,然而,習知複合毛細組織雖確實能夠增益熱管之熱傳導效率,但隨著熱管空間型態的不同,仍舊存在著一些問題點有待改善突破。According to the conventional heat pipe structure design, in order to achieve better heat transfer efficiency, a composite capillary structure type is introduced. However, the conventional composite capillary structure can certainly benefit the heat transfer efficiency of the heat pipe, but with the heat pipe space type Different, there are still some problems that need to be improved.
為因應目前電腦、電子設備的輕薄短小化設計發展趨勢,熱管結構相對必須隨之扁薄化與小型化,惟如此一來,原本設置於熱管內部空間中的複合毛細組織,就會因此而產生一些問題,蓋因,習知熱管中的複合毛細組織就製程面而言,其粉末燒結體的部份通常須採用一芯棒先插入熱管空間中作為一治具,然後於該芯棒與熱管管壁的間隙中填入金屬粉末再加以燒結定型,然此種習知結構型態於實際製造經驗中發現,其金屬粉末並無法達到薄型化的狀態要求,因填粉過程中若間隙過小將難以達成,且隨著熱管長度越長,亦有粉末緊實困難的問題存在,而粉末燒結體的厚度一旦過厚,就會相對造成蒸氣流道空間不足的問題,而此一問題在熱管的截面積足夠的條件下並不致突顯出來,但隨著熱管的截面積扁薄小型化至一定程度時,由 於粉末燒結體所佔截面積比例相對過大,所述蒸氣流道空間不足的問題即突顯而出,且難以改善克服。In order to cope with the current trend of thin and light design of computers and electronic devices, the heat pipe structure must be thinned and miniaturized. However, the composite capillary structure originally installed in the inner space of the heat pipe will be generated. Some problems, Gayne, the composite capillary structure in the conventional heat pipe, in terms of the process surface, the part of the powder sintered body usually needs to be inserted into the heat pipe space as a fixture by a mandrel, and then the mandrel and the heat pipe are used. The gap between the wall of the pipe is filled with metal powder and then sintered and shaped. However, this kind of conventional structural form has found that the metal powder cannot meet the requirements of thinning state, because the gap is too small during the filling process. It is difficult to achieve, and as the length of the heat pipe is longer, there is also a problem that the powder is difficult to be compacted, and once the thickness of the powder sintered body is too thick, the problem of insufficient vapor flow space is caused, and this problem is in the heat pipe. When the cross-sectional area is sufficient, it does not stand out, but as the cross-sectional area of the heat pipe is reduced to a certain extent, The ratio of the cross-sectional area occupied by the powder sintered body is relatively large, and the problem that the vapor flow path space is insufficient is highlighted, and it is difficult to improve the overcoming.
習知熱管複合毛細組織的另一個問題,則是其粉末燒結體與網體一旦被燒結固定於熱管空間後,其可撓曲性就會幾近喪失,如此當熱管須因應需求壓製成扁管或彎管型態時,其管壁曲變部位所對應的複合毛細組織往往難以產生一致性的曲變狀態,造成複合毛細組織與熱管管壁之間相互脫離的現象,而此一現象會同時導致蒸氣流道空間被阻塞、阻斷的情況,進而嚴重影響工作液汽化狀態的流動順暢性,令熱管的散熱效能大打折扣。Another problem with the conventional heat pipe composite capillary structure is that once the powder sintered body and the mesh body are sintered and fixed in the heat pipe space, the flexibility is almost lost, so that when the heat pipe is required to be pressed into a flat pipe according to the demand. In the case of a curved pipe type, the composite capillary structure corresponding to the tortuous portion of the pipe wall is often difficult to produce a consistently curved state, causing the phenomenon that the composite capillary structure and the heat pipe wall are separated from each other, and this phenomenon will simultaneously The situation that the steam flow channel space is blocked and blocked, thereby seriously affecting the flow smoothness of the vaporization state of the working fluid, and the heat dissipation performance of the heat pipe is greatly reduced.
另一方面,習知熱管結構設計上所存在的另一個問題點,則是在於內部毛細組織燒結時位置控制困難不易的問題點,因為習知熱管製程上,無論其內部毛細組織為金屬粉末或網體,其於熱管中欲進行燒結時,所在位置往往不易精準控制而有嚴重偏移、誤差的問題存在,造成配置上通常僅能作全區段型態的設置,若欲針對局部區段作限定式的設置,則有技術上的瓶頸與困難尚待突破,此實為相關業界需再思索突破之重要課題。On the other hand, another problem in the design of the conventional heat pipe structure is that it is difficult to control the position of the internal capillary structure during sintering because the internal capillary structure is metal powder or The net body, when it is intended to be sintered in the heat pipe, is often difficult to accurately control and has serious problems of offset and error, so that the configuration can only be set for the full segment type, if it is intended for the local segment. As a limited setting, there are technical bottlenecks and difficulties that still need to be broken. This is an important issue for the relevant industry to think about again.
是以,針對上述習知熱管構造及製法應用上所存在之問題點,如何研發出一種能夠更具理想實用性之創新構造及製法,實有待相關業界再加以思索突破之目標及方向者。Therefore, in view of the problems in the above-mentioned conventional heat pipe structure and the application of the method, how to develop an innovative structure and method that can be more ideal and practical, and the relevant industry should further consider the goal and direction of breakthrough.

The structural design of the sintered capillary structure in the evaporation section is set to a circular distribution pattern, and the 俾 can amplify the dispersed area when the working fluid is refluxed to the evaporation section. In order to improve the heat vaporization efficiency of the working fluid in the evaporation section of the heat pipe, the practical progress of further improving the heat dissipation effect of the heat pipe is achieved.
4、藉由該粉末限位網體形成金屬粉末填粉製程中限位構件之結構設計,當業界所需熱管成品長度規格較長時,俾可藉由所述粉末限位網體的設置,令金屬粉末燒結的分佈位置能夠臨近熱管開口端(指半成品狀態),藉此而能增進熱管粉末燒結製程的良率與便利性。4. The structural design of the limiting member in the metal powder filling process is formed by the powder limiting net body. When the length of the heat pipe finished product required by the industry is long, the setting of the powder limit net body can be The distribution position of the metal powder sintering can be adjacent to the open end of the heat pipe (referring to the semi-finished state), thereby improving the yield and convenience of the heat pipe powder sintering process.
