Mechanical Definitions |
Heat Distribution Point : The temperature at which a
standard test bar (ASTM test) deflects 0.010 inch (0.254 millimeter)
under a load of either 66 or 264 psi (4.55 x 105 or 18.20 x
105 newtons per square meter) as specified. |
Heat Engine : It is a machine which derives heat energy
from the combustion of fuel and converts the energy into mechanical
energy. |
Heat Exchanger : It is a device which transfers heat
from one build to another or to heating chamber. The part of
an injection mold in which cold plastic feed is changed into
a hot melt. |
Heating Surface : The surface of the absorption and transfer
of heat from one medium to another is called Heating Surface.
|
Heat-loss flowmeter : Any of various instruments which
determine gas velocities or mass flows from the cooling effect
of the flow on an electrical sensor such as thermistor or resistor.
The second sensor is used for compensating the temperature of
the fluid. It can be also termed as thermal-loss meter. |
Heat Pipe : It is a heat transfer device which consists
of a sealed metal tube with an inner lining, wick like capillary
material and a small amount of fluid in a partial vacuum. Heat
is absorbed at one end by vaporization of the fluid and released
by the condensation of the vapor at the other end. |
Heat Pump : It is a machine or device which moves heat
from one location(cooler reservoir) to another(hotter one).
It expands mechanical energy in the process especially when
the main purpose is to heat the hot reservoir rather than refrigerate
the cold one. |
Heat Rate : It is a ratio of the conversion efficiency
of a thermal power plant or engine as heat input per unit of
work output. It is expressed as BTU/kWh |
Heat Seal : It is a union between two thermoplastic surfaces
by application of heat and pressure to the joint. |
Heatsink Cooling : It is a process of cooling a body
or system by allowing heat to be absorbed from it by another
body. |
