Pumped cooling system in gas detector

Abstract:

Embodiments relate to systems and methods for dissipating heat within a gas detector. A gas detector may comprise an airflow generator configured to generate a sample gas flow through the gas detector; a sample gas flow line configured to direct the sample gas flow within a housing of the gas detector from an inlet of the gas detector toward an outlet of the gas detector; a sensor, in fluid communication with the airflow generator via the sample gas flow line, configured to detect one or more potentially hazardous gases within the sample gas flow; and a heat sink, in fluid communication with the airflow generator and positioned after the sensor along the sample gas flow line, configured to transfer heat from an interior of the housing to the sample gas flow, wherein the sample gas flow is directed out of the housing via the outlet of the gas detector.
