HEAT RADIATING DEVICE AND MANUFACTURING METHOD OF HEAT RADIATING DEVICE
First Claim
1. A heat radiating device for radiating heat of a circuit, comprising:
- a first heat pipe which has a first end portion a first straight portion connected to the first end portion, a curved portion connected to the first straight portion, a second straight portion connected to the curved portion and parallel with the first straight portion, and a second end portion connected to the second straight portion;
a first base which is in contact with the circuit and is joined at a first surface thereof opposite to a surface thereof facing the circuit, to the first straight portion;
a plurality of first fins which are provided on the first surface, have flat surfaces perpendicular to the first straight portion, and cross the second straight portion;
a second base which has a second surface perpendicular to the first base and the first straight portion and is joined to the first heat pipe; and
a plurality of second fins which are provided on the second surface and extend to a direction perpendicular to the second surface.

11. A manufacturing method of a heat radiating device for radiating heat of a circuit, comprising:
-
joining a first straight portion of the first heat pipe which has a first end portion, the first straight portion connected to the first end portion, a curved portion connected to the first straight portion, a second straight portion connected to the curved portion and parallel with the first straight portion, and a second end portion connected to the second straight portion, to a first surface of a first base for contacting the circuit, the first surface being opposite to a surface of the first base which faces the circuit; mounting, on the first surface, a plurality of first fins which are provided on the first surface and have flat surfaces perpendicular to the first straight portion; joining the plurality of first fins and the second straight portion so as to cross each other; and joining, to the first heat pipe, a second base which has a second surface perpendicular to the first base and the first straight portion and on the second surface of which a plurality of second fins are provided so as to be perpendicular to the second surface. - View Dependent Claims (12)
