The invention discloses a shape memory alloy driven self-adjusting runner cold plate and a self-adjusting method, comprising an upper cover plate, a lower cover plate and a runner plate positioned between the upper cover plate and the lower cover plate, further comprising a runner with a double-layer structure formed on the upper and lower surfaces of the runner plate, wherein a plurality of mounting grooves for mounting a runner adjustment assembly are arranged on the upper runner; The runner adjusting assembly includes a push rod, a shape memory alloy spring and a spring on the push rod, anda movable runner wall fixed on the push rod. The inner surface of the upper cover plate is provided with a heat conduction mechanism which is in contact with the mounting groove; A liquid work mediumis filled in that mount groove; The heat conduction mechanism of shape memory alloy spring and the liquid working fluid heat transfer make the elastic force change, and then drive the push rod to push the movable flow channel
