<p>The present invention reliably extinguishes fires in devices that have exceeded the guaranteed temperature without the use of a sensor. An in-vehicle fire extinguisher (100) extinguishes fires using an air conditioner for heating or cooling the interior of a vehicle compartment. A coolant discharged from a compressor (101) is pumped into the compressor (101) through a circulation path (106) via a condenser (102), an expansion valve (103) and an evaporator (105). A fire extinguishing unit (104) is provided to the circulation path (106) between the expansion valve (103) and the compressor (101). When a device mounted in a vehicle exceeds the guaranteed temperature, the fire extinguishing unit (104) melts so that coolant pumped from the circulation path (106) is discharged to the exterior and extinguishes the device fire.</p> |
