Document Type and Number:
WIPO Patent Application WO/2021/132171
Kind Code:
A1
Abstract:
A cooling structure (50) is provided with: a body (10) including a base (11) and heat-dissipating fins (13) and a protrusion (13T) which protrude from a heat-dissipating surface (12); a lid member (20) disposed so as to cover the protrusion (13T) and the heat-dissipating fins (13) and forming a flow path (18); and a fan mechanism (30). The fan mechanism (30) includes a blade (31b), a driver (31a) for rotating the blade, and a wire (31c) for supplying electric power to the driver. The protrusion (13T) has a first through-hole (13h). The base (11) has a second through-hole (11h) in communication with the first through-hole (13h). The wire (31c) is connected to the driver and includes a first portion (31d) disposed between the lid member (20) and the body (10), and a second portion (31e) continuous with the first portion (31d) and passed through the first through-hole (13h) and the second through-hole (11h). With the cooling structure, it is possible to improve heat-dissipating performance and sealing performance.
