可選的，前述熱傳導元件20及第一熱傳導元件20a與第二熱傳導元件20b在另一實施如第5E圖所示為一平板式熱管，具有一外殼61係為平板狀並界定有一腔室63，該腔室63內設有一毛細結構64及一工作流體65。該外殼61具有一上側611及一下側612，該上側611及該下側612其中任一側作為一吸熱側，另一則作為散熱側，在本實施係表示該上側611作為散熱側202、202a、202b，該下側612作為吸熱側201、201a、201b。該毛細結構64係可形成在該腔室63內提供毛細力令該工作流體65回流，並支撐在該外殼61的上側611及下側612之間作為支撐使用。毛細結構64係以燒結粉末體做說明，但並不侷限於此，該毛細結構64亦可選擇為金屬網或纖維體或螺旋編織體。該工作流體65例如純水、無機化合物、醇類、酮類、液態金屬、冷煤或有機化合物，透過工作流體65在腔室63內汽液循環的作用以令下側612的熱量傳遞到上側611散熱。 Optionally, the heat conduction element 20 and the first heat conduction element 20a and the second heat conduction element 20b are shown in another embodiment as shown in FIG. 5E as a flat heat pipe, and the outer casing 61 has a flat shape and defines a chamber 63. A capillary structure 64 and a working fluid 65 are disposed in the chamber 63. The outer casing 61 has an upper side 611 and a lower side 612. One of the upper side 611 and the lower side 612 serves as a heat absorbing side, and the other side serves as a heat dissipating side. In the present embodiment, the upper side 611 is shown as a heat dissipating side 202, 202a. 202b, the lower side 612 serves as the heat absorption side 201, 201a, 201b. The capillary structure 64 is formed to provide a capillary force in the chamber 63 to recirculate the working fluid 65 and is supported between the upper side 611 and the lower side 612 of the outer casing 61 for use as a support. The capillary structure 64 is described as a sintered powder body, but is not limited thereto, and the capillary structure 64 may also be selected as a metal mesh or a fibrous body or a spiral braid. The working fluid 65, such as pure water, inorganic compounds, alcohols, ketones, liquid metals, cold coal or organic compounds, is vaporized by the working fluid 65 in the chamber 63 to transfer heat to the lower side 612 to the upper side. 611 heat dissipation.
所以透過本發明在電路板115的第一側1151及/或第二側1152設置熱傳導元件20、20a、20b，得有效大幅增加穿戴式主機裝置之散熱效能，以降低主體11內產生積熱的問題，進而還有效讓使用者穿戴時能獲得較佳的舒適感的效果。 Therefore, by providing the heat conduction elements 20, 20a, and 20b on the first side 1151 and/or the second side 1152 of the circuit board 115, the heat dissipation performance of the wearable host device can be greatly increased to reduce the heat generation in the main body 11. The problem is further effective in allowing the user to obtain a better comfort when wearing.
惟以上所述者，僅係本發明之較佳可行之實施例而已，舉凡利用本發明上述之方法、形狀、構造、裝置所為之變化，皆應包含於本案之權利範圍內。 It is to be understood that the above-described methods, shapes, configurations, and devices of the present invention are intended to be included within the scope of the present invention.
