ASFN90391

DC fans are components used to move air or other gases in an enclosure to provide cooling or to exhaust harmful gases. They are used to cool hot components in a system and to provide cooling to CPUs, chipsets and other heat-dissipating components. There are two main types of DC fans – axial and centrifugal – that use different methods to move air or gases.

Axial fans use an impeller and blades to create a low-pressure region inside the housing. The air around the housing then moves into the low-pressure region, thereby providing airflow to the components. On the other hand, centrifugal fans use an impeller mounted inside a housing which is connected to a motor. The motor spins the impeller at high speeds and forces air into the housing, creating an air stream that is ejected from the rear of the fan.

ASFN90391 is a DC fan that utilizes axial-flow fan technology to provide cooling. It has a fan motor that is rated for 7.2 VDC and 0.25 A of current and the impeller blades are made from die-cast aluminum alloy. The fan is capable of operating at a maximum speed of 4325 rpm and a maximum air flow rate of 4 m3/min. It also has a noise rating of 32 dBA.

In terms of application, the ASFN90391 DC fan is suitable for cooling of components in electronic systems and can also be used in ventilation systems. It can be used to cool CPUs, chipsets, graphic cards, power supplies, heatsinks, inverters and various other heat-dissipating components. It is also suitable for use in commercial and industrial applications where fast and efficient cooling is required.

The working principle of the ASFN90391 DC fan is very simple. When the fan motor is activated, it rotates the impeller at high speeds, producing a low-pressure zone inside the housing. The air surrounding the fan housing then moves in, and is forced out of the fan housing with greater velocity due to the design of the blades. This creates an airflow which is directed towards the components requiring cooling.

To summarize, the ASFN90391 DC fan is a reliable cooling solution for devices that require fast and efficient cooling. It utilizes axial-flow fan technology to force air through the housing, directing it towards the components that require cooling. The fan motor is rated for 7.2VDC and 0.25A of current, with a maximum speed of 4325rpm and a maximum air flow rate of 4m3/min. It is suitable for cooling CPUs, chipsets, graphic cards, power supplies, heatsinks, inverters and various other heat-dissipating components.
