The **CTPH-55-R/Q** is a high-performance, precision-engineered thermal component, specifically a **Heat Pipe** assembly often utilized in industrial cooling and power electronics. These parts are critical for thermal management in systems where heat needs to be moved away from sensitive electronic components rapidly. --- ### 1. Key Technical Specifications While specific data can vary by manufacturer (often associated with brands like Wakefield-Vette or specialized thermal vendors), the "55" typically refers to the physical length or a specific thermal capacity rating. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Heat Pipe (Phase-change cooling device) | | **Material** | Oxygen-free High Thermal Conductivity Copper (OFHC) | | **Working Fluid** | De-ionized Water (typically under vacuum) | | **Wick Structure** | Sintered Powder or Grooved (for orientation flexibility) | | **Suffix R/Q** | Often denotes "RoHS Compliant" and "Quality/Standard Grade" | --- ### 2. Operating Mechanism The electronic functionality of the CTPH-55-R/Q relies on the physics of **Phase Change**: 1. **Evaporation:** Heat from an electronic component (like a CPU, IGBT, or MOSFET) enters the "Evaporator" section. The internal fluid turns to vapor. 2. **Transportation:** The vapor travels through the hollow core to the "Condenser" section (usually attached to a finned heat sink). 3. **Condensation:** The vapor loses heat, turns back into liquid, and is wicked back to the heat source via capillary action. --- ### 3. Application in Electronics These parts are integrated into electronic systems to prevent **Thermal Throttling** and component failure. * **Power Converters:** Used to cool high-voltage inverters and converters. * **Telecommunications:** Cooling for base station transceivers where airflow is limited. * **Embedded Computing:** Providing slim-profile cooling for ruggedized industrial PCs. --- ### 4. Selection Criteria When integrating the CTPH-55-R/Q into a circuit design, engineers look at the following: * **Q-Max:** The maximum power (in Watts) the heat pipe can transfer before reaching "dry out." * **Thermal Resistance ($R_{th}$):** Measured in °C/W; lower values indicate better efficiency. * **Bending Radius:** The physical limits of how much the pipe can be shaped without collapsing the internal wick structure. ---
