摘要

The cabinet has mounting plates (6) arranged parallel to walls (5) of the cabinet, and electrical components arranged on the plates. Heat developed in internal space is released by the walls. A circulating unit circulates the air present in the space around the components for cooling. The upper and lower openable air way is formed in the walls at the rear side of the mounting plates, and the circulating air flows via the air way.
