A Peltier junction is the same as a thermocouple junction, except instead of using heat to generate electric current an electric current is forced through it to move heat. Thus in a heatsink unit one junction (on the hot IC) gets cold removing heat and the other junction (on the heatsink fins) gets very hot. Thus it acts like a electric refrigeration system for the IC.
It has no moving parts (except maybe a fan) like the compressor and coolant in mechanical refrigerators. It is even reversible to make a heater by just reversing the electric current. Portable electric food cooler/heater units are available, these typically plug into a car cigarette lighter outlet.
What else can I help you with?
What is the name of a heat sink carrying an electrical charge that causes it to act as an electrical thermal transfer device?
a peltier
The peltier's top surface can be as cool as?
The Peltier's top surface can reach temperatures close to the ambient temperature of the heat sink it is attached to. The cooling capacity of the Peltier device depends on factors like the input power, efficiency, and thermal resistance of the system.
What is a popular alternative to the heat sink?
Either a cold plate, used with Peltier, or TEC (Thermo Electric Cooling) or a water block used with water cooling systems.
What is a Peltier diode?
answer by engr ZOHAIB MUSHTAQ WHEN EMF APPLY AT TWO DIFFERENT ENDS OF METALLIC PLATE HAVING COMBINE JUNCTION HERE ONE END IS HOT AND OTHER END IS COLD THIS EFFECT IS PELTIER EFFECT
How does a Peltier fan work to regulate temperature in electronic devices?
A Peltier fan uses the Peltier effect to regulate temperature in electronic devices. When an electric current flows through the Peltier device, it creates a temperature difference between its two sides. One side absorbs heat, while the other side releases it, helping to cool the device.
What is the function of a processor heat sink?
To sink the heat.
How does a heat sink work in the power supply?
A heat sink works on the principle of thermal transfer. The heat sink transfers heat from the chip to the air, wicking heat away.
Is water a type of heat sink?
Yes! Water is a heat sink.
Why is it called a heat sink?
Probably because it draws/absorbs the heat making the heat "sink" into it
How does a thermoelectric refrigerator work?
According to Wikipedia:"Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other side against the temperature gradient (from cold to hot), with consumption of electrical energy. Such an instrument is also called a Peltier device, Peltier diode, cooling diode, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). Because heating can be achieved more easily and economically by many other methods, Peltier devices are mostly used for cooling. However, when a single device is to be used for both heating and cooling, a Peltier device may be desirable. Simply connecting it to a DC voltage will cause one side to cool, while the other side warms. The effectiveness of the pump at moving the heat away from the cold side is dependent upon the amount of current provided and how well the heat can be removed from the hot side."A peltier cooler is not a thermopile nor a thermocouple and it does not rely on the seebeck effect.
