 Design and Construction

1. Blade Design and Material

The blades of the 12038 DC axial fan are carefully crafted to ensure optimal air flow. They are typically made from high - quality materials that offer a combination of strength, durability, and lightweight properties. Engineering plastics such as polycarbonate or acrylonitrile - butadiene - styrene (ABS) are commonly used. These materials are able to withstand the mechanical forces during rotation without adding excessive weight to the fan. The shape of the blades is based on advanced aerodynamic principles. They usually have a curved or airfoil - like profile. This design allows the blades to effectively capture and accelerate the air molecules as they rotate. The blade pitch, which is the angle of the blades relative to the axis of rotation, is precisely engineered. For the 12038 fan, the blade pitch is set to maximize the air volume and pressure within the design constraints. A proper blade pitch ensures that the fan can generate the desired air flow characteristics, whether it's for high - volume but low - pressure applications or vice versa.

2. DC Motor Design

The 12 - volt DC motor of the 12038 axial fan is a crucial part of its operation. DC motors can be either brushed or brushless. In the case of brushed motors, they consist of a commutator and carbon brushes. The commutator and brushes work together to supply current to the rotor windings, enabling the motor to rotate. The quality of the brushes and commutator is of high importance as they affect the motor's lifespan and performance. For brushless motors, which are becoming more popular due to their advantages, electronic commutation is used. This eliminates the need for brushes, reducing wear and tear and maintenance requirements. Brushless motors also tend to be more energy - efficient and can provide better speed control. The motor in the 12038 fan is designed to operate optimally at 12 volts. It is sized and engineered to provide the necessary torque to rotate the fan blades at the desired speed. The motor's winding and magnetic circuit are carefully designed to ensure efficient conversion of electrical energy into mechanical energy.

3. Housing Design and Material

 Working Principle

The 12038 DC axial fan operates based on the principle of axial flow. When the 12 - volt DC motor rotates the blades, the blades exert a force on the air molecules in the axial direction. This creates a pressure difference between the inlet and the outlet of the fan. As a result, air is drawn in from the inlet and is pushed out along the axis of rotation at the outlet. The speed of the motor directly affects the volume of air moved and the pressure generated. By varying the voltage within a certain range around the 12 - volt nominal value, the speed of the fan can be adjusted. This allows for control of the air flow rate and pressure according to the specific requirements of the application. For example, in a cooling system, the fan speed can be increased during periods of high heat load to provide more cooling air.
