摘要: 
本論文實驗探討P4(Pentium4)RHE 散熱模組之熱管結合散熱鰭
片的散熱性能分析。在設定熱管熱傳導率,熱管相關尺寸,風扇性能
曲線,鰭片相關尺寸(如長度、間距、厚度)及片數、材質等條件下
分析散熱鰭片形狀參數,以期獲得RHE 較佳散熱效果。
本文所欲探討的散熱鰭片形狀共有A、B、C、D、E 組的形狀,其
中A 組為RHE 散熱鰭片43 片規則外形,B 組為RHE 新形散熱鰭片43
片,C 組為RHE 新形散熱鰭片31 片,D 組為RHE 新形散熱鰭片20 片,
E 組為RHE 新形散熱鰭片10 片。
在散熱設計中,不論是利用自然對流或是強制對流,一般最終透

熱過程中,散熱鰭片與空氣間之熱傳效果,常是最具關鍵之設計所
在。故在五種不同外形散熱鰭片下尋找最佳散熱效果。
實驗分析發現,因改變外型下鰭片沒有足夠的熱擴散面積,間接

度約上升2~4.6℃,散熱效率下降16.7~28.6%。

The experiment of this thesis explores the cooling
capability of the heat pipe of P4 (Pentium4) RHE thermal module
in combination with cooling fins. Under the conditions of
established heat pipe thermal conductivity rate, heat
pipe-related size, fan capability curve, fin-related size
(such as length, spacing, thickness, number of fins and
material, We analyzed the cooling fin shape parameters, to
achieve bester RHE cooling effect.
The cooling fin shapes explored in this thesis have shapes
of A, B, C, D, and E. Of which are 43 regularly shaped A RHE
cooling fins, 43 new model B RHE cooling fins, 31 new model C
RHE cooling fins, 20 new model D RHE cooling fins, and 10 new model E RHE cooling fins.

Cooling designs, regardless of free convection or forced
convection, generally employ cooling fins to dissipate CPU heat
to the air. The key in the design is usually the convection
effect between cooling fins and the air. Therefore, the best
cooling effect is sought among the five cooling fins with different shapes.
Research analysis finds that a modified fin without
sufficient thermal diffusion surface will indirectly lower the
cooling efficiency of RHE. In the modified RHE thermal module
fin shape, the temperature of the RHE thermal module increased
between 2 to 4.6℃, the cooling efficiency decreased between
16.7 to 28.6%.
