Apart from the working limitations resulting from its structural property, the flat plate heat pipe carries out heat dissipation through the evaporation and condensation of the working fluid. Thus, if the working angle of the fluid is adverse to its backflow, the heat pipe will fail easily. Furthermore, not the orientations of all the heat sources are favorable to the functioning of the heat pipe. To compensate for this drawback, this research focuses primarily on the development of a composite structure which will reduce the effect of gravity on the working fluid. Generally speaking, the heat pipe is divided into three main categories: the groove type, sintered metal type and mesh screen type, as shown in Table 2. As far as capillary force is concerned, the sintered metal type and mesh screen type show better performance. As mentioned in R.

平板式热管除了因其结构特性而产生的工作极限之外，由于其作用乃是透过工作流体的蒸发及凝结进行散热，故若是其工作角度不利于液体之回流，便容易使热管失效，且并非所有之发热源都是位于有利于热管工作之位置，因此本研究之主要目的为设计一可减少重力对工作流体影响之复合式结构；一般而言，热管之结构大致可分为沟槽、烧结及网格三种(如表2所示)，其中烧结及网格结构有较佳之毛细力，在 R。
