Q. How can you tell which is the hot and which is the cold side of a module?

A. Visit our technical reference page, how to fit a thermoelectric module guide for information

Q. How do I mount a thermoelectric module into a system?

A. Visit our technical reference page for information about how to do this.

Q. What is the difference between a peltier cooler module and a peltier generator module?
A. Both types of module use the thermoelectric effect. This effect is reversible so that both module types can act as a cooler or a generator; if a voltage is applied to a module, it will pump heat, but if a temperature difference is applied across a module a voltage will be produced.

Q. What is the difference between heat spreading and heat removal?
A. Heat spreading is normally used to prevent hot spots and increase the surface area available for transfer, this is an important thermal management technique in hand held devices, e.g. mobile phones or tablets. Heat removal involves the transfer of heat energy from a source e.g. a micro-processor into a transfer medium, typically a fluid.
