  2. Thermoelectric cooling - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_cooling

    Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

  3. Furuno - Wikipedia

    en.wikipedia.org/wiki/Furuno

    Furuno Electric Shokai was founded in Nagasaki, Japan in 1948. The same year, Furuno commercialized the world's first practical fish finder.Manufacturing continued to ramp up as the decade came to a close, and by the mid-1950s, Furuno was producing various Marine supplements, such as early examples of commercial Marine radars.

    The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.

    In contrast, the beam of a PESA radar can rapidly be changed to point in a different direction, simply by electrically adjusting the phase differences between different elements of the passive electronically scanned array (PESA). In 1959, DARPA developed an experimental phased array radar called Electronically Steered Array Radar (ESAR). It was ...

  7. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    Cold-side heat removal with air: In air-cooled thermoelectric applications, such as when harvesting thermal energy from a motor vehicle's crankcase, the large amount of thermal energy that must be dissipated into ambient air presents a significant challenge. As a thermoelectric generator's cool side temperature rises, the device's differential ...

  8. Heat wave or heat dome? Yes, there's a difference - AOL

    The term 'heat dome' has gained prominence recently as climate change, El Niño and other variables have warmed global temperatures and shifted weather patterns.

  9. Heat pump and refrigeration cycle - Wikipedia

    en.wikipedia.org/wiki/Heat_pump_and...

    Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
