Patent ID: 7502228

Claim:
A heat transfer mechanism for dissipating heat from a heat generating body to a heat dissipating part, the heat generating body being directly coupled, at its bottom surface, to a common board, comprising: a film-shaped heat conductor for transferring heat from a top surface of the heat generating body to the heat dissipating part; and an elastic member directly coupled, on one hand, with said heat dissipating part and, on the other hand, with said film-shaped heat conductor, the length of which is shorter than the length of the top surface of said heat generating body, for imparting elasticity to the film-shaped heat conductor, said film-shaped heat conductor being formed from a metal foil-type flexible heat pipe, wherein said film-shaped heat conductor has a double bent shape of two parallel legs connected by a middle portion that offsets the two parallel legs with obtuse angles and transfers heat from the top surface of the heat generating body to the heat dissipating part along the double bent heat conductor by sandwiching the lower portion of said double bent heat conductor between said heat generating body and said elastic member so that said lower portion of said double bent heat conductor makes direct contact with substantially an entire top surface of said heat generating body, and coupling the upper portion of said double bent heat conductor directly to said heat dissipating part by extending said upper portion of said double bent heat conductor beyond an end portion of said heat generating body.
