heat transfer resistance
11Thermal resistance in electronics — Thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time. It is the reciprocal of thermal conductance. The SI units of thermal resistance are kelvins per watt, or the equivalent… …
12Concentric tube heat exchanger — Concentric Tube (or Pipe) Heat Exchangers are used in a variety of industries for purposes such as material processing, food preparation and air conditioning.[1] They create a temperature driving force by passing fluid streams of different… …
13Plate heat exchanger — A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the… …
14Loop heat pipe — A loop heat pipe (LHP) is a two phase heat transfer device that uses capillary action to remove heat from a source and passively move it to a condenser or radiator. LHPs are similar to heat pipes but have the advantage of being able provide… …
15Refractories heat-up — After building of a new refractory lined industrial furnace or equipment, or refractory maintenance or relining of existing equipment, a necessary step is the start up of the operation, which usually involves heating up the unit in a controllable …
16Maximum power transfer theorem — In electrical engineering, the maximum power transfer theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must be equal to the resistance of the source as viewed from… …
17Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …

19СОПРОТИВЛЕНИЕ ТЕРМИЧЕСКОЕ — [heat transfer resistance; thermal resistance] отношение разности температур поверхности слоя к плотности теплового потока через него …
20Lumped capacitance model — A lumped capacitance model, also called lumped system analysis,[1] reduces a thermal system to a number of discrete “lumps” and assumes that the temperature difference inside each lump is negligible. This approximation is useful to simplify… …
