ABSTRACT:
Disclosed is a two-stage thermoelectric heat pumping apparatus for heating/cooling an I.C. chip. The first stage is a primary thermoelectric module sandwiched between a base made of a high thermal conductivity material and functioning as a heat source/sink and a heat conductive pad. The second stage is a secondary thermoelectric module sandwiched between the pad and a heat conductive block designed to receive a slotted I.C. chip socket at the top portion thereof and provided with a contact surface such that, upon insertion into the socket, the chip is in direct contact with said contact surface. By passing suitable currents through all the thermoelectric modules heat is pumped, in the heating mode, from the base (source) to the chip and, in the cooling mode, from the chip to the base (sink).
