FIELD: construction, particularly special arrangements or devices in connection with roof coverings, namely building ventilation systems to prevent ice and icicle formation on roof edges.
SUBSTANCE: device has heat pipes having evaporation sections arranged in exhaust air vent channel (airway) and condensation sections secured under grain pipes and gutters of building roof. Heat pipes have flexible sections connecting condensation and evaporation sections and provided with inner flexible wicks. Flexible heat pipe section is fastened to condensation and evaporation sections by means of plug-type connectors built in condensation and evaporation sections. Evaporation zone of heat pipe comprises filling pipe with shutoff valve.
EFFECT: increased heat pipe assemblage convenience and prevention of attic room and passageway obstruction.
