該作動液51,本實施例以純水為例,注入於該蒸發腔11,被該毛細材13所吸附,並存在於迴路熱管10的部分位置。The working fluid 51, in this embodiment, pure water is taken as an example, injected into the evaporation chamber 11, absorbed by the capillary material 13, and exists in a part of the loop heat pipe 10.
以上說明了本第一實施例的架構,接下來說明本第一實施例的使用狀態。The structure of the first embodiment has been described above, and the use state of the first embodiment is described next.
藉由上述結構,於實際的操作過程中,將一發熱源(如電子裝置)置放於該蒸發腔11上,當該發熱源(圖未示)運作一段時間後會產生熱,該發熱源以熱傳導的方式將熱傳遞至該蒸發腔11,並且將熱導向該毛細材13,作動液51大部份以液態形式儲存於該毛細材13中,當熱導入該毛細材13時,該毛細材13的溫度上升,使儲存於毛細材13內液態作動液吸收足夠的熱量後,逐漸蒸發形成汽態作動液,汽態作動液由該毛細材13其複數個通道131之每一個通道口132往該蒸發空間125移動並匯集,之後,再進入該汽流管31、並往該冷凝件21的方向繼續前進,由該汽接端212進入該冷凝件21內。藉由該冷凝件21外部設置的散熱單元100,使通過該冷凝件21之汽態作動液將熱散到空氣中,汽態作動液因為冷卻而凝結成水滴狀的液態作動液,且附著於該冷凝件21的管壁。而,隨著冷凝的液態作動液愈來愈多,水滴狀的液態作動液即愈來愈大,且因該冷凝件21的液接端213口徑較小,水滴狀的液態作動液可以比較快的佔滿液接端213、並且進入該液流管41形成佔滿該液流管41截面的液彈511。更藉由該液流管41的口徑較小,在沒有毛細力的情況下可以藉由汽流管31與液流管41內的壓力差來推動液彈511,使液彈511可以在液流管41內流動的更為容易與快速,再加上汽態作動液不斷的由該汽流管31進入至該冷凝件21,會形成一股推動液彈511前進的力量,最後再流回該蒸發腔11內被該毛細材13所吸附。如此循環作用,即可不斷的將發熱源的熱能導出,達到良好的散熱效果。With the above structure, a heating source (such as an electronic device) is placed on the evaporation chamber 11 during actual operation. When the heating source (not shown) is operated for a period of time, heat is generated. The heating source The heat is transferred to the evaporation chamber 11 by heat conduction, and the heat is directed to the capillary material 13. Most of the working fluid 51 is stored in the capillary material 13 in a liquid form. When heat is introduced into the capillary material 13, the capillary The temperature of the material 13 rises, so that the liquid working fluid stored in the capillary material 13 absorbs enough heat, and then gradually evaporates to form a gaseous working fluid. The gaseous working fluid is passed from the capillary 13 to each of the channel openings 132 of the plurality of channels 131. Move to the evaporation space 125 and collect, and then enter the steam flow pipe 31 and continue to advance in the direction of the condensing element 21, and enter the condensing element 21 from the steam connection end 212. With the heat dissipating unit 100 provided outside the condensing member 21, the vapor-phase operating fluid passing through the condensing member 21 dissipates heat into the air, and the vapor-phase operating fluid condenses into a droplet-like liquid operating fluid due to cooling, and is attached to The tube wall of the condensing element 21. However, as more and more condensed liquid actuating fluids are formed, the liquid actuating fluids in the shape of water droplets are becoming larger and larger, and because the liquid end 213 of the condensing member 21 is smaller, the liquid actuating fluids in the shape of water droplets may be faster. The liquid filling terminal 213 fills the liquid flow tube 41 and forms a liquid bomb 511 that fills the cross section of the liquid flow tube 41. Furthermore, the diameter of the liquid flow tube 41 is small. In the case of no capillary force, the liquid bomb 511 can be pushed by the pressure difference between the vapor flow tube 31 and the liquid flow tube 41, so that the liquid bomb 511 can flow in the liquid flow. The flow in the tube 41 is easier and faster. In addition, the gaseous actuating fluid continuously enters the condensing member 21 from the vapor flow tube 31, which will form a force that propels the liquid bomb 511 forward, and finally flows back to the evaporation. The inside of the cavity 11 is adsorbed by the capillary material 13. In this way, the thermal energy of the heating source can be continuously exported to achieve a good heat dissipation effect.
由上可知,本發明將液流管41設呈管徑較小於汽流管31,且連接該汽流管31與該液流管41的冷凝件21亦設呈液接端213的孔徑較小於該汽接端212,因此可以在截面積較小的該液流管41內形成液彈511(如第3圖所示),並且在沒有毛細力的情況下可以藉由汽流管31與液流管41內的壓力差來推動液彈511,進而使得液態作動液回流至該蒸發腔11更為順暢與快速。As can be seen from the above, in the present invention, the liquid flow pipe 41 is set to have a smaller diameter than the steam flow pipe 31, and the condensation piece 21 connecting the steam flow pipe 31 and the liquid flow pipe 41 is also set to have a smaller diameter than the liquid connection end 213. It is smaller than the steam connection end 212, so a liquid bomb 511 can be formed in the liquid flow tube 41 with a small cross-sectional area (as shown in FIG. 3), and the steam flow tube 31 can be used without capillary force. The pressure difference with the liquid flow tube 41 pushes the liquid bomb 511, so that the liquid operating liquid returns to the evaporation chamber 11 more smoothly and quickly.

The type with a smaller pore diameter at the liquid junction 213 "and a larger pore diameter at the vapor junction 212" can form the liquid working fluid with the effect of a liquid bomb 511 ", and without the capillary force by the steam The pressure difference between the flow tube 31 "and the liquid flow tube 41" promotes the liquid bomb 511 ", so that the liquid bomb 511" can flow more smoothly in the liquid flow tube 41 "(as shown in Fig. 8). The liquid operating fluid can be returned to the evaporation chamber 11 "more smoothly and quickly, and the heat dissipation efficiency of the loop heat pipe of the present invention can be improved.
前述第三較佳實施例中之該第一孔123”與該第二孔124”位於該容置盒122”的同一側,則該汽流管31”與該液流管41”組設於該容置盒122”的同一側,該冷凝件21”的汽接端212”與液接端213”的設置能配合供該汽流管31”與該液流管41” 插組並得與該流通通道211”連通即可;又,亦可以使該第一孔123”與該第二孔124”位於該容置盒122”的不同側,該汽流管31”與該液流管41”組設於該容置盒122”的不同側,該冷凝件21”其流通通道211”的二端貫通矩形塊體的二側,該流通通道211”二端的汽接端212”與液接端213”同樣設為對應可供該汽流管31”與該液流管41” 插組的結構,如第二實施例所示的型態,同樣可達提高本發明迴路熱管散熱效率的功效,於本說明書中不另外再以圖式表示。In the third preferred embodiment, the first hole 123 "and the second hole 124" are located on the same side of the containing box 122 ", and the steam flow tube 31" and the liquid flow tube 41 "are arranged in On the same side of the accommodating box 122 ", the arrangement of the steam connection end 212" and the liquid connection end 213 "of the condensing member 21" can be adapted for the steam flow tube 31 "and the liquid flow tube 41" to be inserted and combined with each other. The circulation channel 211 "may be communicated with each other; the first hole 123" and the second hole 124 "may be located on different sides of the containing box 122", and the steam flow pipe 31 "and the liquid flow pipe 41 "The two ends of the condensing member 21" whose flow channel 211 "penetrates the two sides of the rectangular block, and the steam connection ends 212 of the two ends of the flow channel 211" are connected to the liquid connection. The end 213 "is also set to correspond to the structure that can be used to insert the steam flow tube 31" and the liquid flow tube 41 ". The type shown in the second embodiment can also improve the heat dissipation efficiency of the loop heat pipe of the present invention. In this specification, it will not be represented by a diagram.
