Internal Energy and Heat. A thermal system has internal energy (also called thermal energy), which is the sum of the mechanical energies of its molecules.A system''s internal energy is proportional to its temperature. As we saw earlier in this chapter, if two objects at different temperatures are brought into contact with each other, energy is transferred from the hotter to
Managing the Heat Produced by X-ray Tubes
Thus, a 50W X-ray tube will produce roughly 49.8W of energy in the form of heat just through the conversion process. Add to this the thermal energy produced by the helical tungsten filament and one can readily see that heat dissipation is a major factor. Inadequate cooling of an X-ray tube can cause it to fail in two ways.
Thermal Dissipation: The Ultimate Cooling Guide
Thermal dissipation is the process of dispersing heat away from a heat source to prevent overheating, typically through conduction, convection, or radiation.
