Abstract
A safety radiator cap for radiator providing a safety plate or wire made of shape memory alloy. The safety plate or wire bends downward under ambient temperature. High temperature water in the radiator causes the safety plate to extend out due to the memory characteristic of the alloy, and the safety plate thus presses against the neck of the filling hole.
