CERAMIC
MATERIAL
The
ceramic material used in the construction of the thermoelectric cooler
can be chosen to optimize the performance of the cooler design. The
ceramic materials exhibit unique attributes that may be beneficial in
some applications and not in others. The thermoelectric coolers are
typically constructed of three types of ceramic materials; Alumina,
Beryllia, and Aluminum Nitride. A thermoelectric cooler need not be
constructed out of the same ceramic material for both the top and base.
For instance, you may chose to use Beryllia on the top for better heat
spreading and Alumina on the base for a better thermal match to your
package. Although these materials have demonstrated reliable performance
in thermoelectric applications, other materials may be available to meet
your specific needs. Contact
Marlow engineering to determine your material options, or simply fill
out the applications
questionnaire, and you will receive detailed results of the
thermoelectric cooler configuration that matches your requirements.
The table below
compares some of the ceramic material attributes.
