The **F2TS-70-R/BL** belongs to a series of high-performance thermal management components, specifically a **Cross-Flow Fan** (also known as a Tangential Fan). These are commonly used in electronic cooling where a wide, uniform airflow is required in space-constrained environments. --- ### 1. Key Technical Specifications Below are the typical electronic and physical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Type** | Cross-Flow / Tangential Fan | | **Operating Voltage** | 110V - 230V AC (Standard series range) | | **Impeller Diameter** | 70 mm | | **Material** | Aluminum Alloy (Impeller), Steel (Frame) | | **Bearing Type** | Dual Ball Bearing or Sleeve | | **Color Code** | R/BL (Red/Black wiring or housing markers) | | **Motor Type** | Shaded Pole or Capacitor-run Induction Motor | --- ### 2. Core Electronic Components The device functions through several integrated electronic parts: * **Induction Motor:** The heart of the unit. It uses electromagnetic induction to rotate the long, cylindrical impeller. * **Stator Windings:** Copper coils that generate the magnetic field. In "BL" (Brushless) variations, these are controlled by a PCB. * **Thermal Protector:** Usually integrated into the windings to prevent the motor from burning out if the impeller is jammed (Auto-restart or thermal cutoff). * **Lead Wires:** Typically UL-rated wiring (often Red and Black, as denoted by the suffix) for power connection. --- ### 3. Application Areas Because of its unique "long and thin" shape, the F2TS-70 series is used in: 1. **Server Racks:** To provide a curtain of air across multiple blade servers. 2. **HVAC Systems:** For uniform air distribution in air curtains. 3. **Power Supplies:** Cooling high-density electronic circuits. 4. **Display Cases:** Preventing condensation on glass while cooling internal electronics. --- ### 4.
