Abstract
A fan for ventilating electrical and electronic equipment includes a fan housing adapted to be plugged in a printed circuit board and having a duct for allowing air to flow. The fan housing is positioned substantially upright with respect to the printed circuit board. The duct has a fan wheel of a fan arranged therewithin. An electric motor is coupled to the fan housing for driving the fan wheel. At least three fasteners are coupled to at least part of the fan housing for fixing the fan on the printed circuit board. A power supply adapter, which is coupled to at least part of the fan housing, includes connectors that provide electrical connection to the printed circuit board for supplying power to the electric motor.
Claims31
A fan for ventilating electrical and electronic equipment, comprising:
- a fan housing adapted to be plugged in a printed circuit board and having a duct for allowing air to flow, longer edges of the fan housing being positioned parallel with respect to the printed circuit board;
- a fan having a fan wheel arranged in the duct;
- an electric motor coupled to the fan housing for driving the fan wheel;
- at least three fasteners coupled to at least part of the fan housing for securing the fan on the printed circuit board;
- and
- a power supply adapter coupled to at least part of the fan housing, the power supply adapter having connectors for providing electrical connection to the printed circuit board for supplying power to the electric motor.
A ventilation fan, comprising:
- a fan housing connected with a printed circuit board and having a duct through which air flows;
- a fan wheel disposed in the duct for providing the air flow therewithin;
- an electric motor coupled to the fan housing for driving the fan wheel;
- a plurality of fasteners coupled to at least part of the fan housing for connecting the fan housing with the printed circuit board;
- and
- a power supply adapter connected with the fan housing with the printed circuit board, the adapter supplying power to the electric motor.
A fan that ventilates electronic equipment, comprising:
- a cylindrical tubular fan housing removeably and replaceably secured to a printed circuit board and having a duct for allowing air to flow, where the duct has a flange formed on a surface thereof;
- a fan wheel disposed in the duct, an inner diameter of the fan housing adapted to the radius of the fan wheel;
- an electric motor coupled to the fan housing for driving the fan wheel;
- a plurality of columnar fasteners coupled to the flange and to the fan housing, where the fasteners connect the fan housing with the printed circuit board;
- and
- a power supply adapter connected with the flange and in pluggable connection with the printed circuit board, the adapter supplying power to the electric motor, where associated electronic components of the electric motor are integrated in the power supply adapter.
