Cpu cooling circuit having thermoelectric element

Abstract

A CPU cooling circuit for a CPU includes a thermoelectric element and a current source circuit. The thermoelectric element includes a first thermoelectric substrate attached to the CPU, a second thermoelectric substrate opposite to the first thermoelectric substrate, a plurality of n-type semiconductor units and p-type semiconductor units alternately sandwiched between the first and the second thermoelectric substrates and electrically connected in series between a positive power supply input and a negative power supply input. The current source circuit is configured for providing driving current to flow through the n-type semiconductor units and the p-type semiconductor units of the thermoelectric element according to a temperature of the CPU.
