Document Type and Number:
WIPO Patent Application WO/2023/228438
Kind Code:
A1
Abstract:
In the present invention, a plate-shaped heat dissipation fin installed on the main surface of a base plate comprises: a fin root part which extends from one end to the other end of the plate-shaped heat dissipation fin in the width direction along the main surface of the base plate, connected to the main surface of the base plate; and a twisted part that is provided continuously from the fin root part in the height direction of the plate-shaped heat dissipation fin, and is inclined toward the main surface of the base plate. The twisted part has a planar region defined by a twist start part that is lengthened in a linear state from the fin root part along the height direction of the plate-shaped heat dissipation fin, one end part which is at least a portion of one end facing the twist start part, and that is inclined by angle θ1 to the main surface direction of the base plate with respect to the twist start part, and a fin tip part which is at least a portion of the fin tip facing the fin root part, and that is inclined by angle θ2 along the extension direction of the main surface of the base plate facing the one end part from the twist start part.
