  2. Deep water source cooling - Wikipedia

    en.wikipedia.org/wiki/Deep_water_source_cooling

    Deep water source cooling (DWSC) or deep water air cooling is a form of air cooling for process and comfort space cooling which uses a large body of naturally cold water as a heat sink. It uses water at 4 to 10 degrees Celsius drawn from deep areas within lakes, oceans, aquifers or rivers, which is pumped through the one side of a heat exchanger .

  3. 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:

  4. Passive cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_cooling

    Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]

  5. Heat spreader - Wikipedia

    en.wikipedia.org/wiki/Heat_spreader

    A heat spreader transfers energy as heat from a hotter source to a colder heat sink or heat exchanger. There are two thermodynamic types, passive and active. The most common sort of passive heat spreader is a plate or block of material having high thermal conductivity, such as copper, aluminum, or diamond. An active heat spreader speeds up heat ...

    "Kids' bodies produce heat faster than adults and they can't get rid of that heat as quickly," she explains. As a result, children can get sick in extreme heat, and do so faster than many adults ...

  7. Refrigeration - Wikipedia

    A heat sink then absorbs the heat released by the refrigerant due to its loss of entropy. Thermal contact with the heat sink is then broken so that the system is insulated, and the magnetic field is switched off. This increases the heat capacity of the refrigerant, thus decreasing its temperature below the temperature of the heat sink.

  8. How can you protect yourself and kids from the extreme heat?

    Heat waves like the one the U.S. is experiencing this week can dramatically increase death rates and drive up hospital visits and heat illness cases. Heat is also unhealthy. Heat and humidity's ...

  9. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    Heating water directly is inherently more efficient than heating it indirectly via heat exchangers, but such systems offer very limited freeze protection (if any), can easily heat water to temperatures unsafe for domestic use, and ICS systems suffer from severe heat loss on cold nights and cold, cloudy days.
