A micro heat pipe’s (MHP) performance is largely determined by its capillary limit. Based on comprehensive analyses of lower backflow resistance of working fluid in trapezium-grooved-wick MHP and greater capillary suction in a sintered-wick MHP, this paper established the mathematical model of capillary limit for a MHP with the compound structure of a sintered wick on trapezium-grooved substrate. The analyses show that a MHP with such compound structure has a higher capillary limit than that a MHP with a simplex sintered- or trapezium-grooved wick structure.
