Description

  The present invention relates to a cooling device, and more particularly to an electric reel motor cooling device for cooling a motor held by a holding member fixed to a reel body of an electric reel that feeds fishing line forward.

  In an electric reel that rotates a spool in a yarn winding direction with a motor, a cooling fin is provided on a holding member that holds the motor in order to cool the motor. With only the radiating fins, particularly when the motor is enlarged, the radiating efficiency may not be sufficient. Therefore, a motor cooling device for an electric reel using a heat pipe for escaping heat generated from a motor or a motor driving unit that drives the motor to the outside is known (for example, see Patent Document 1). In a conventional motor cooling device, a heat transfer part provided in a motor or a motor driving part and a heat radiating part provided in an upper part of a reel body are connected by a heat pipe. And the heat which generate | occur | produces in a motor or a motor drive part is released to the upper part of a reel main body via a heat pipe. The heat dissipating part is fixed to the lower surface of a plate-like connecting part provided for providing a counter in the reel body.
