Abstract

PURPOSE: To make easier the setting of device which gives alarm for stop or decrease of coolant flow, by setting a temperature detection device at close place of heat source placed in the flow path of coolant.
CONSTITUTION: Cooled device 14, thermister type temperature detection device 111 and electric heater 112 which has a low resistance, are set in the air flow tube 1. The device 14 is cooled by cold air sent by fun 15 in the tube. An alarm is released by the alarm device 12 when the temperature detector 11 detected a temperature being more than the fixed value, and also when the detector 111 detected a temperature being more than the alarm temperature, which is caused by decreasing coolant flow due to some troubles of fun.
