Semiconductor Condenser Peltier Thermoelectric Dehumidifier 5
What is the thermoelectric cooling?
Thermoelectric cooling is a way to pump heat from one side of a
device to the other by applying voltage between two electrodes
connected to a sample of semiconductor material. The temperature
differential that appears, which is known as the Peltier Effect,
can be used for cooling, heating and precise temperature control
for various applications.
How do the thermoelectric cooler work?
Thermoelectric coolers, are solid-state heat pumps that require DC
voltage to dissipate heat using the Peltier effect. A
Thermoelectric cooler consists of an array of p-and n-type
semiconductor materials that are soldered between two ceramic
plates. During operation, electric current flows through the module
to create heat transfer and a temperature differential across the
ceramic plates resulting in one cold and one hot side of the
What are the advantages of using thermoelectric cooler instead of
Thermoelectric coolers are highly reliable because they have a
solid-state construction with no moving parts. They are also known
for having a high mean time between failures (MTBFs). It is
difficult to estimate the lifetime of a thermoelectric cooler, due
to the variables in application conditions such as changes to heat
load, on/off cycling, heat or cooling, drive circuit and system
design with protection against condensation. All variables can
influence the product’s lifetime.
However, for demanding applications such as modern diagnostic,
which require high rates of thermal cycling, thermoelectric coolers
have been tested to withstand over 1,000,000 thermal cycles without
degradation in performance.
