Abstract:
1. A heat dissipating device comprising: a container body defining an inner space therein and having opposite heating and cooling ends, a fluid passage disposed between said heating and cooling ends, and opposite upper and lower walls extending from said heating end to said cooling end; a working fluid received in said inner space in said container body; a wick structure mounted in said inner space in said container body and extending from said heating end to said cooling end of said container body to permit liquid flow from said cooling end to said heating end of said container body by virtue of capillary mechanism when a vapor flow resulting from heating of said working fluid at said heating end flows to said cooling end of said container body; and a sealing material that seals said fluid passage of said container body; wherein one of said upper and lower walls has a wall portion that is disposed adjacent to said fluid passage and that is depressed to form a first depression indented inwardly of said inner space in such a manner that said depressed wall portion of said one of said upper and lower walls cooperates with the other of said upper and lower walls to form a sealing mechanism that functions to isolate said fluid passage from said inner space.
