<p>[Problem] To provide a leak detecting structure capable of detecting a leak at an early stage when a small amount of flammable refrigerant gas has leaked from a temperature regulating device that uses flammable refrigerant and that comprises a circulation route. [Solution] A leak detecting structure (10) comprises a leak detecting space (12) into which a mixed gas of flammable refrigerant gas, which is gas leaked from a circulation route, and a temperature regulating gas flows, and a leak detecting sensor (13) that detects leaks of the flammable refrigerant gas. The leak detecting space (12) is provided with an inlet port (14) by which the mixed gas flows into the leak detecting space and an outlet port (15) from which the temperature regulating gas, which is separated from the mixed gas, flows. The inlet port (14) is disposed in a position that is lower than the outlet port (15), and the leak detecting sensor (13) is disposed below the inlet port (14) in the leak detecting space (12).</p> |
