PURPOSE:To enable leakage water to be exactly detected, by arranging a detector chamber into which the leakage water of a cooler and the water of condensation flow, and a tank having an orifice for the outflow of the condensation at the lower section of the detector chamber. CONSTITUTION:The lower section of a detector 4 is provided with an orifice 5, and a small quantity of water like condensation water is not stored in a water leakage detector chamber 3 and is designed to be dripped to a lower section through the orifice 5. A large quantity of water like leaked water in comparison with the quantity of water passing the orifice 5 and not to be dripped to the lower section is stored in the water leakage detector chamber 3, and when the water rises to a specified level, then current is conducted to the detector 4, and alarm or trip signal is generated. As a result, only on the leakage of water, the detector can be exactly operated.
