Abstract: With the fast development of the electronic technology, the flux of electronic products becomes higher and higher. And the effect of high temperature on normal work of the electronic equipment is becoming more and more serious. Higher requirements for cooling technology for the electronic equipment are necessary due to high heat flux. This paper introduces in detail the operation principle and applications of some high performance cooling measures such as forced air cooling, heat pipe and micro channel cooling. Combined with the related literature, this paper also briefly introduces the application of new cooling methods such as the gas jet cooling, spray cooling and thermoelectric refrigeration to electronic equipment with high heat flux.
