Cooling device for a protective respiratory apparatus

A protective respiratory apparatus for the respiration of a person, the protective respiratory apparatus comprising:

• a respiratory-air circuit;
• an air reservoir connected to the respiratory-air circuit;
• a respiratory-air regenerator is arranged in the respiratory-air circuit;
• and
• at least one cooling device arranged downstream of the respiratory-air regenerator in the respiratory circuit the at least one cooling device comprising:
• a housing;
• a respiratory bag arranged in the housing with an inlet for respiratory air and an outlet for cooled respiratory air;
• a spring plate with a spring device to apply a spring force to the respiratory bag;
• a cooling channel formed between the housing and at least one section of an outer side of the respiratory bag, wherein the cooling channel is connected to the ambient air outside the housing in a fluid-communicating manner;
• and
• a blower arranged for the generation of a flow of the ambient air into or through or both into and through the cooling channel.
