Abstract:

A thermoelectric heat pump cascade and a method of manufacturing such are disclosed herein. In some embodiments, a thermoelectric heat pump cascade includes a first stage plurality of thermoelectric devices attached to a first stage circuit board and a first stage thermal interface material between the thermoelectric devices and the heat spreading lid over the thermoelectric devices. The thermoelectric heat pump cascade component also includes a second stage plurality of thermoelectric devices attached to a second stage circuit board where the second stage plurality of thermoelectric devices has a greater heat pumping capacity than the first stage plurality of thermoelectric devices, and a second stage thermal interface material between the second stage plurality of thermoelectric devices and the first stage plurality of thermoelectric devices. In this way, a greater temperature difference can be achieved while allowing for protection of the thermoelectric devices, simplifying design, and improving reliability of the product.
