Title:
HEATSINK STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/244628
Kind Code:
A1
Abstract:
[Problem] To provide a heatsink structure that, even when a flow path area is limited, achieves improvement in cooling performance while minimizing pressure loss in cooling fluid. [Solution] A heatsink structure 1 comprising: a corrugated fin 2 of metal formed in a wavy cross sectional shape and having a plate surface 20 with openings of a plurality of through-holes 21…; a heat-absorbing portion 3, 4 for absorbing heat of an object to be cooled and transmitting the heat to the corrugated fin 2; and a fluid flow path 5 for supplying a cooling fluid toward the plate surface 20 of the corrugated fin 2 and thereby causing the fluid to flow along the through-holes 21…. The heat transmitted from the heat-absorbing portion 3, 4 to the corrugated fin 2 is dissipated into the fluid flowing through the through-holes 21….
