A heater core is a radiator -like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air. Fins attached to the core tubes serve to increase surface area for heat transfer to air that is forced past them by a fan, thereby ...
Thermosiphon. Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces ...
The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
Croatia's main tourism resort, the southern Adriatic Sea town of Dubrovnik, recorded 28 degrees Celsius (82.4 Fahrenheit) at dawn, signalling there won't be relief when the sun goes down.
A Surprising Part of a Kitchen That Can Be the "Star of the Show" "When you find the right backsplash, you can work around that," Hall tells Parade. That's why looking at backsplash was one of the ...
Certain residential buildings must now have at least one air conditioned common area for cooling when the heat index exceeds 80 degrees (26.6 C) and cooling is unavailable in individual units.
In most vehicles, at least one car outlet is present. Some vehicles may have more power outlets: usually one for the front passengers, one for the rear passengers and one for the luggage trunk. The voltage of the power outlet is usually near 12 V DC , and may be elevated between 13.5 V to 15 V while the engine is running.
Crookes tubes are cold cathode tubes, meaning that they do not have a heated filament in them that releases electrons as the later electronic vacuum tubes usually do. Instead, electrons are generated by the ionization of the residual air by a high DC voltage (from a few kilovolts to about 100 kilovolts) applied between the cathode and anode ...
