The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have input powers as low as 2–3 W. Large systems, such as those used for cooling the superconducting magnets in particle accelerators are more often called cryogenic refrigerators. Their input powers can be as high as 1 MW.
For cooling these devices, the solid state nature of the Peltier plates outweighs their poor efficiency. Thermoelectric junctions are typically around 10% as efficient as the ideal Carnot cycle refrigerator, compared with 40% achieved by conventional compression cycle systems.
This is generally known as Thermal Throttling in the case of reduction of clock speeds, or Thermal Shutdown in the case of a complete shutdown of the device or system. Cooling may be designed to reduce the ambient temperature within the case of a computer, such as by exhausting hot air, or to cool a single component or small area (spot cooling).
Active cooling systems are usually better in terms of decreasing temperature than passive cooling systems. Passive cooling doesn't utilize much energy for its operation but instead takes advantage of natural cooling, which takes longer to cool over a long period of time. Most people prefer the use of active cooling systems in hot or tropical ...
It is intended to reduce rapidly the person's temperature to below 34 °C (93 °F) while targeting the brain as the first area of cooling. Research into the device has shown cooling rates of 2.6 °C (4.7 °F) per hour in the brain (measured through infrared tympanic measurement) and 1.6 °C (2.9 °F) per hour for core body temperature reduction.
The Arctic Sun has adhesive gel pads which stick to a patient's body, and cover only a portion of a patient's body to leave most of the body free for augmenting medical procedures. The device operates under negative pressure and circulates water through the adhesive pads at a temperature between 4–42 °C (39–108 °F).
