The utility model discloses a cooling water alarm device, relating to the improved technology of cooling equipment. It comprises a cooling water pipeline, a thermocouple, a temperature controller and an alarm; the thermocouple is mounted on the cooling water pipeline, connected to the temperature controller via a wire, and the temperature controller is connected to the alarm. The utility model can promptly detect whether the cooling water temperature of a hollow blow molding machine is within the process range. The core control device of the utility model is a temperature controller: the thermocouple detects the outlet water temperature of the chiller and feeds it back to the temperature controller; the temperature controller compares the feedback temperature with the set value, and sends a signal to control the alarm if the temperature exceeds the set range.
