Solid state cooling systems are solid state heat pumps that operate utilizing the Peltier
effect. When a cooling solution is required, the choices are conventional refrigeration
techniques and solid state cooling (also known as thermoelectric cooling.)
Conventional refrigeration uses a compressor, condenser, evaporator, and refrigerants
to accomplish the task of cooling. These systems have mechanical components, and can
be noisy and cause vibration. Anyone who has heard their own refrigerator or air
conditioning unit knows the associated circumstances. The main advantage is that
conventional refrigeration can be use for large-scale cooling applications.
Solid state cooling systems use a thermoelectric device, consisting of a semiconductor
based bi-metal junction, a heat sink, and DC power. A typical solid state cooling
system is a semiconductor–based component, soldered between two ceramic plates, with a
sandwich-type structure filled with bismuth telluride particles and doped to obtain N-P
junctions. When current is passed through the junction of the two different conductors,
a temperature change is achieved. There are no moving parts and no refrigerants. A
solid state cooling systems is very good for smaller, quiet applications.
Advantages of Solid State Cooling Systems
Solid state cooling systems have no moving parts. For that reason, they offer high
reliability and low maintenance over other types of cooling or heating devices. Solid
state cooling systems offer low noise performance and are ideal for use in medical
offices, laboratories and all other places where noise reduction is a factor. Solid state
cooling systems are ecologically clean - no CFC, HCFC or even HFC types of refrigerants
are involved in the process.
In addition, a solid state cooling system is ideal for temperature control, allowing the
system to maintain temperature accuracy of +/- 0.1 degrees Celsius. Another advantage of
using a solid state cooling system is the easy to switch from cooling to heating by just
reversing polarity of flowing DC current. In many applications this is extremely useful.
