  2. Thermal management (electronics) - Wikipedia

    en.wikipedia.org/wiki/Thermal_management...

    According to Telcordia GR-3028, Thermal Management in Telecommunications Central Offices, the most common way of cooling modern telecommunications equipment internally is by utilizing multiple high-speed fans to create forced convection cooling. Although direct and indirect liquid cooling may be introduced in the future, the current design of ...

  3. Active cooling - Wikipedia

    en.wikipedia.org/wiki/Active_cooling

    Active cooling is a heat-reducing mechanism that is typically implemented in electronic devices and indoor buildings to ensure proper heat transfer and circulation from within. Unlike its counterpart passive cooling, active cooling is entirely dependent on energy consumption in order to operate. It uses various mechanical systems that consume ...

  4. External Active Thermal Control System - Wikipedia

    en.wikipedia.org/wiki/External_Active_Thermal...

    The EATCS is capable of rejecting up to 70 kW, and provides a substantial upgrade in heat rejection capacity from the 14 kW capability of the Early External Active Thermal Control System (EEATCS) via the Early Ammonia Servicer (EAS), which was launched on STS-105 and installed onto the P6 Truss.

  5. Spacecraft thermal control - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_thermal_control

    The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).

  6. Passive daytime radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_daytime_radiative...

    The polyacrylate hydrogel film [70] from the 2022 study has broader applications, including potential uses in building construction and large-scale thermal management systems. This research focused on a film developed for hybrid passive cooling.

  7. Heat sink - Wikipedia

    en.wikipedia.org/wiki/Heat_sink

    The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:

  8. Concentrated photovoltaic thermal system - Wikipedia

    en.wikipedia.org/wiki/Concentrated_photovoltaic...

    Two major procedures of ventilation of solar collectors are active ventilation and passive ventilation. With passive ventilation, the heat generated in the surface of the collector is transmitted to the air by heat sink. With active ventilation, the heat can be used for cooling or heating purposes. So, active ventilation converts a CPV system ...

  9. Computer cooling - Wikipedia

    en.wikipedia.org/wiki/Computer_cooling

    Passive heatsink cooling involves attaching a block of machined or extruded metal to the part that needs cooling. A thermal adhesive may be used. More commonly for a personal computer CPU, a clamp holds the heatsink directly over the chip, with a thermal grease or thermal pad spread between. This block has fins and ridges to increase its ...
