Definitions

  • the present invention relates to a motor fan attached to a heat exchanger such as a radiator or a condenser of an automobile, and more particularly to a motor fan that can efficiently cool a controller that controls driving of an electric motor.
  • a large amount of air is forcibly passed through a core by a motor fan.
  • the motor fan guides the air flow toward the heat exchanger by covering the space between the periphery of the motor fan and the heat exchanger with a shroud so that the air taken in by the motor fan does not escape sideways.
  • the motor fan that makes the rotation speed variable includes a controller that controls driving of the electric motor.
  • a PWM (Pulse Width Modulation) unit is used.
  • a power element when the drive of the electric motor is controlled, a built-in power semiconductor switching element generates heat.
  • the motor fan that makes the rotation speed variable has a configuration for cooling a controller that includes a power element that serves as a heating element.
  • Patent Document 1 proposes to install a controller inside the shroud and to form a rib that guides air around the controller to the motor fan side.
  • the proposal of patent document 1 is that the excessive temperature rise of a heat generating body can be suppressed by forming a rib and preventing air from stagnating around a controller.
  • Patent Document 2 presupposes that the PWM unit is disposed facing the fan opening so that the air flow generated by the fan is applied to the PWM unit for forced cooling, and the PWM unit occupies the fan opening. Means capable of changing the area are provided. In Patent Document 2, for example, when the flow rate of the air flow is required to be large so that the PWM unit does not hinder the air flow, the occupied area is reduced.

However, even if the occupied area of the PWM unit in the fan opening can be changed to be small, it cannot be denied that the air flow interferes with the PWM unit and hinders the air flow. Therefore, Patent Document 2 inevitably generates noise in addition to a decrease in the air flow rate.
