unit 20 is arranged in theaccommodation space 13 of the sealingenvelope 10 and divides theaccommodation space 13 into aretaining region 131 and twoempty regions 132. Theretaining region 131 is functioned to accommodate the heat-guidingunit 20 and the heat-guidingunit 20 comprises awick structure 21 and a workingfluid 22 attached to thewick structure 21. Thewick structure 21 could be one of unwoven cloth, metal mesh, sintered metal or other porous material. The workingfluid 22 could be liquid with low boiling point such as water, methyl alcohol, acetone, ammonia, coolant or the mixture of above liquids. Moreover, the heat-guidingunit 20 could be extended to the empty regions 132 (not shown). - To assemble the heat dissipating apparatus of the present invention, the heat-guiding
unit 20 is placed in theretaining region 131 and then a radio frequency heating machine is used to seal the peripheral of thesealing envelope 10.
