Abstract
A plate type heat pipe comprises: a plate type container which includes a heat absorbing side and a heat dissipating side to form a hermetically sealed hollow portion; at least one heat transfer block which is thermally connected to each of inner walls of the heat absorbing side and the heat dissipating side; a wick which is placed along a side wall of the heat transfer block through the inner wall of the heat dissipating side; and a working fluid enclosed in the hollow portion. A securing member to secure the wick and the heat transfer block in close contact may be further included.
Claims5
A method of manufacturing a plate type heat pipe comprising:
- preparing a container including a hollow portion by a plate member as a heat dissipating side and a worked plate member as a heat absorbing side including at least one protruding portion;
- preparing a heat transfer block having a prescribed size and a netlike wick having a prescribed size;
- arranging a securing member and said heat transfer block in at least one protruding portion within said hollow portion of said container;
- placing said netlike wick along from a side wall of said heat transfer block through an inner wall of said heat dissipating side;
- arranging said netlike wick so as for a tip of said netlike wick to be pinched between said side wall of said heat transfer block and said inner wall of said protruding portion;
- securing an upper surface and a lower surface of said heat transfer block in close contact to said inner wall of said heat dissipating side and said inner wall of said heat absorbing side, respectively, while said heat transfer block is pushed against said inner wall of said protruding portion by said securing member to secure in close contact said netlike wick and said heat transfer block;
- and
- reducing a pressure within said hollow portion and enclosing a prescribed amount of working fluid.
