Peltier Thermoelectric Cooler Multi Stage TEC Module Best Cooling
Thermoelectric technology is an active thermal management technique
based on the Peltier effect. It was discovered by J.C.A Peltier in
1834, this phenomenon involves the heating or cooling of the
junction of two thermoelectric materials(bismuth and telluride) by
passing current through the junction. During operation, direct
current flows through the TEC module causing heat to be transfered
from one side to the other. Creating a cold and hot side. If the
direction of the current is reversed, the cold and hot sides are
changed. Its cooling power also can be adjusted by changing its
operating current. A typical single stage cooler (Figure. 1)
consists of two ceramic plates with p and n-type semiconductor
material (bismuth ,telluride) between the ceramic plates. The
elements of semiconductor material are connected electrically in
series and thermally in parallel.
Thermoelectric cooling module,Peltier device,TEC modules can be considered as a type of solid-state thermal
energy pump, and due to its actual weight, size and the rate of
reaction, it is very suitable to be used as part of the inbuilt
cooling systems (due to limitation of space). With advantages such
as quiet operation, shatter proof, shock resistance, longer useful
life and easy maintenance, modern thermoelectric cooling
module,peltier device,TEC modules have a wide range application in
the fields of military equipments, aviation, aerospace, medical
treatment, epidemic prevention, experimental apparatus, consumer
products (water cooler, car cooler, hotel refrigerator, wine
cooler, personal mini cooler, cool & heat sleep pad, etc).
Today, because of its low weight, small size or capacity and low
cost, thermoelectric cooling is widely used in medical,
pharmaceutical equiment, aviation, aerospace, military, spectrocopy
systems, and commercial products(such as hot& cold water dispenser,
portable refrigerators, carcooler and so on)
