AIR DECONTAMINATING HEAT EXCHANGER AND HEATER Russian patent published in 2021 - IPC F24H3/00 A61L9/00 F24F3/16 

FIELD: power engineering.

SUBSTANCE: heater includes a casing, a fan, a burner and a heat exchanger with a body, installed relative to the casing with a gap for air passage, the heat exchanger is made with at least one channel inside the body of the heat exchanger body for the passage, heating and decontamination of air, and the elements of the channel direct the air flow to the channel wall heated by the burner. The channel inside the body of the heat exchanger for the passage, heating and decontamination of air is made zigzag-shaped, wherein each previous elbow of the channel directs the air flow to the wall of the next elbow, heated by the burner. The heater includes a cylindrical casing and a fan, a burner and a heat exchanger with a cylindrical body with an axisymmetrical hole in the end wall for the burner located inside the body and holes for entrance of the air into the channels, and with holes for output of the heated and decontaminated air on the periphery of the opposite end wall of the body, all located in the casing consequently and axisymmetrically, wherein the throughput capacity of the channels inside the body of the heat exchanger exceeds the throughput capacity of the gap between the casing and the body of the heat exchanger by more than 10 times.

EFFECT: invention allows heating microdrops in the process of passage of the air flow through the heat exchanger to a temperature exceeding the temperature of denaturation of proteins and nucleotides of pathogenic microbes.
