II. Core Products and Applications
As a deep player in the field of heat dissipation, we focus on our core business of cooling fans (heat dissipation fans). Structurally, our products cover three major categories: axial flow cooling fans, centrifugal fans, and DC blowers, with a complete range of sizes and specifications, meeting the adaptation needs of over 90% of equipment in the industrial field. (This data comes from the market equipment analysis and statistics of Dongxingyue R&D department)
(1) Product size
1. Axial flow cooling fan: 30mm–280mm (usually referring to length and width dimensions)
2. Centrifugal fan: 100mm–310mm (usually referring to diameter)
3. DC blower: 40mm–120mm (usually referring to length and width dimensions)
(II) Working principle
1. Axial-flow cooling fan: When the fan operates, the fan blades rotate, driving airflow. This airflow moves along the axial direction of the fan's impeller, hence the term "axial-flow fan"
2. Centrifugal fan: When the fan operates, the impeller rotates, drawing in airflow axially and expelling it radially under the influence of centrifugal force. The airflow expelled is referred to as a centrifugal fan
3. DC Blower: When the fan operates, the impeller rotates, drawing in airflow axially and expelling it radially due to centrifugal force. The airflow is then guided by the housing to a single outlet, resembling a snail shell structure. Dongxingyue Blower only has a DC power supply series, hence it is called a DC blower.
(III) Power supply voltage
1. Axial-flow cooling fan: The power supply voltage for axial-flow fans can be either direct current (DC) or alternating current (AC to DC). DC voltages mainly include 5V/12V/24V/48V, while AC voltages mainly include 110V/220V. Therefore, axial-flow fans, combining their cooling function and voltage parameters, are also referred to as DC cooling fans, AC cooling fans, 5V cooling fans, 12V cooling fans, 24V cooling fans, 48V cooling fans, 110V cooling fans, and 220V cooling fans.
2. Centrifugal fan: DC 12V/24V/48V; EC 110V/220V
3. DC Blower: DC5V/12V/24V/48V (with slight variations depending on size)
(IV) Core functions
1. PWM pulse speed regulation: With a frequency range of 100Hz–30KHz, it supports precise speed adjustment
2. FG speed feedback: Monitor and output fan speed signals in real time
3. RD operation alarm: Automatically output warning signals in case of locked-rotor or abnormal conditions
4. TC temperature control and speed regulation: Equipped with a built-in sensor, it automatically adjusts the speed according to the ambient temperature
5. Soft Start (SS): Reduce starting current to protect fan components and the power supply system
6. Locked-rotor protection/automatic restart: Power-off protection in case of abnormalities, with automatic retry startup after a 5-second interval
7. Waterproof and dustproof: IPX5–IPX8/IP65–IP68 levels are optional, using vacuum coating/potting processes
8. Large-size enhancement function: Fans ≥120mm support current limiting, resistance speed regulation, constant speed, and reverse polarity protection
(V) Supporting accessories
We provide supporting products such as protective net covers, dustproof net covers, and shutters to meet the equipment's needs for anti-collision, dustproof, and waterproof protection.
(VI) Application Fields
