Motor with cooled rotor

摘要

A fan includes an air movement implement including a blade and a motor that drives the air movement implement. The motor includes a rotor that includes an internal diameter heat exchanger and a heat pipe having a first end and a second end, the first end in thermal contact with the internal diameter heat exchanger and the second end in thermal contact with the blade.

主权项

1. A system comprising:
an air intake; a first heat exchanger coupled to the air intake; an air output coupled to the first heat exchanger; and a fan disposed within the air output that causes air to be drawn in the air intake, through the heat exchanger and expelled through the air output, the fan including:
an air movement implement including a blade; anda motor that drives the air movement implement and includes:
a rotor that includes an internal diameter heat exchanger; a heat pipe having a first end and a second end, the first end extending from and in thermal contact with the internal diameter heat exchanger and the second end in thermal contact with the blade, the heat pipe having an inner diameter that defines an internal passageway fluidly coupled to receive air from the internal diameter heat exchanger; a cooling duct coupled between the air intake and the motor that provides air that has not passed through the first heat exchanger to the motor, wherein the passageway is fluidly coupled to the cooling duct.
