Be derived from the thermally conductive heat of hot gas, this conduction heat be experience electric energy-conversion-radiant heat-conversion-air heat-
Conversion-aluminium liquid heat.The first law of thermodynamics illustrates that the energy of multi-form can be changed, but in transformation process
Middle preservation of energy.The second law of thermodynamics then point out energy except the amount of having number in addition to also have grade height,
The energy conversion of different grades is that the ability of work(is different.The mistake of three conversions that heat is experienced from electric energy to aluminium liquid
Journey, reality is all the low-grade conversion of high-grade energy, and the acquisition amount of available power is very few.A lot
Electric energy due to switch acceptor aluminium liquid heat inefficient, miss in transformator with transmission line of electricity.Therefore,
For saves energy, need electric heating element can place be a lower temperature in the environment of work it is also desirable to
