1. Electronics
Every electronic device operates efficiently at a certain temperature called the optimum
temperature of the operation. Major part of electronics is based on semi-conductors and
temperature control for these devices are very important.
1.1Why Electronics components need temperature control [1]
Every electronic component shows some resistance accompanied by heat
generation, continued miniaturization of electronic systems has resulted in a
dramatic increase in the amount of heat generated per unit volume, failure rate of
electronic equipment increases exponentially with temperature, so to avoid failure
temperature control is required.

In order to control the heating heat sinks are
used in computers for cooling of processors
and on main IC’s.[1]
Temporary heat sinks were sometimes used
while soldering circuit boards, preventing
excessive heat from damaging sensitive nearby
electronics[3]

Large server rooms works 24/7 to provide backup, their temperature control is the most
important point to keep it running continuously.
Voltage Regulator IC and FET are provided with their separate heat sinks because of their
high heat production.[1]

Cell Phones are the most compact form of computers they also have the proper heat
dissipation path to avoid thermal throttling of devices.
Battery lives gets prolonged at a slightly lower temperature than room temperature.[3]
Rectifier Circuit and power supply units require temperature control for its working.[4]

Heat sinks for cooling.[5]

Industrial machines which are composed of electronic components require different
temperature ranges for their functions.
Industries running PLC units have their own cooling system to maintain temperatures.
