  • Patent number: 6772829
    Abstract: An improved heat exchange apparatus for insertion in a housing comprises heat exchange tubes extending substantially parallel to a direction of fluid flow through the housing and a plurality of spaced and circumferential fins formed along the heat exchange tubes and extending substantially perpendicular to the direction of fluid flow through the housing. Preferably the housing is fit with a fluid mover for driving the fluid over the tubes. The improved heat exchanger can be applied in a method for extermination of pests comprising providing a minimal envelope, heating ambient air within the envelope using the improved heat exchanger and discharging the heated air into the envelope so that the temperature of air in the envelope is sufficiently high to kill pests. Moving air across steam filled tubes enables use of the system in explosion classified areas and without damage to goods or equipment.
