Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208384
Kind Code:
A1
Abstract:
The inside of a housing of a power conversion device (1) is partitioned by partitioning walls, and the power conversion device (1) is configured from an open section (10), into which external air flows, a first airtight section (20), which is adjacent to the open section (10), and into which external air does not flow, and a second airtight section (30), which is adjacent to the first airtight section (20), and into which external air does not flow. At least two ventilation holes (22) are formed in a partition wall (21) between the first airtight section (20) and the second airtight section (30). A circulation fan (25) is provided to at least one of the ventilation holes (22). The outer surface of the first airtight section (20) is provided with a heat sink (23) that dissipates heat transferred from an electronic component housed in the first airtight section (20), said heat sink being exposed to the open section (10).
