HEAT-DISSIPATION DEVICE AND POWER GENERATION DEVICE

摘要

The present invention addresses the problem of providing a heat-dissipation device which is resistant to damage when exposed to vibrations, and which has good heat-dissipation properties. The heat-dissipation device (1) is provided with a base portion (2), a fin portion (3), and an airflow passageway (4). The fin portion (3) is provided with a plurality of fins (5) which protrude from the base portion 2 in a first direction (D1) and which are arranged in a second direction (D2) crossing the first direction (D1), and a reinforcement portion 6 connected to adjacent two fins (5) of the plurality of fins (5). The airflow passageway (4) is surrounded by the plurality of fins (5) and the reinforcement portion (6) in the fin portion (3), and is open in the first direction (D1).
