Abstract
A cooling element for use within a cooling device of a closed-circuit respirator, includes an element housing, which has a liquid-tight cap and is filled with a coolant, which has a melting point below 50° C., especially below 45° C., preferably below 40° C. A sensor element is arranged in contact with the coolant within the element housing such that the sensor element can be moved in a direction of the gravity acting on the sensor element in the liquid state of the coolant during the use of the closed-circuit respirator by a user of the closed-circuit respirator.
