Cooling apparatus of liquid-cooling type

摘要

A cooling apparatus comprises an outlet port through which cooling air is applied in a radial direction, a plurality of heat radiating fins which are arranged at intervals and which surround the outlet port, and first to third paths in which liquid coolant flows. The first path extends in the direction the heat radiating fins are arranged and is thermally connected to a second edge of each heat radiating fin. The second path extends in the direction the heat radiating fins are arranged and is thermally connected to a first edge of each heat radiating fin. The third path which connects a downstream end of the first path and an upstream end of the second path.
