Heat print that page

171879main_LimbFlareJan12_lg

In physics and thermodynamics , heat is energy transferred from one body, region, or thermodynamic system to another due to thermal contact when the systems are at different temperatures. It is also often described as one of the fundamental processes of energy transfer between physical

Heat transfer print that page

Hot_metalwork

Heat conduction, also called diffusion, is the direct microscopic exchange of kinetic energy of particles through the stationary boundary between two systems. Heat conduction occurs between stationary masses where there is no movement to carry heat away. Heat transfer through the stationary

Heat index print that page

The heat index ( HI ) is an index that combines air temperature and relative humidity in an attempt to determine the human-perceived equivalent temperature — how hot it feels, termed the felt air temperature . The human body normally cools itself by perspiration , or sweating , which

Canned Heat print that page

Canned_Heat_at_Woodstock_Reunion_1979

The music and attitude of Canned Heat afforded them a large following and established the band as one of the popular acts of the hippie era. Canned Heat appeared at most major musical events at the end of the 1960s and they were able to deliver on stage electrifying performances of blues standards

Heat pump print that page

Heat_Pump

A heat pump is a machine or device that diverts heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature using mechanical work or a high-temperature heat source. [ 1 ] A heat pump can be used to provide heating

Heat sink print that page

AMD_heatsink_and_fan

A heat sink is a term for a component or assembly that transfers heat generated within a solid material to a fluid medium, such as air or a liquid. Examples of heat sinks are the heat exchangers used in refrigeration and air conditioning systems and the radiator (also a heat exchanger) in

Heat exchanger print that page

PHE_Trieste_013

A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact. [ 1 ] They are widely used in space heating , refrigeration , air conditioning , power

Heat engine print that page

In thermodynamics , a heat engine is a system that performs the conversion of heat or thermal energy to mechanical work . [ 1 ] [ 2 ] It does this by bringing a working substance from a high temperature state to a lower temperature state. A heat "source" generates thermal energy that brings

Heat pipe print that page

Laptop_Heat_Pipe

A heat pipe or heat pin is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two solid interfaces . At the hot interface within a heat pipe, which is typically at a very low pressure
