HEATER FOR VEHICLE AND HEATING SYSTEM

摘要

FIELD: transport engineering; heating systems. ^ SUBSTANCE: proposed heater contains burner 42a, and heat exchanger 16a to transfer heat of combustion formed in burner 42a to heated medium. Heat exchanger 16a has first heat-exchange section 56a and second heat-exchange section 70a to transfer heat of combustion to heat gaseous and liquid media, accordingly. Heat exchanger 16 has heat-exchange body 40a with guide chamber for gaseous combustion products fitted inside. First heat-exchange section 56a has great number of heat transfer ribs 62a arranged on heat-exchange body 40a and forming heat transfer surfaces 64a. Second heat exchange section 70a is provided with device to pass flow of second heated medium. Said flow passing device contains at least one guide pipeline passing in zone of heat-transfer ribs 62a for medium. At least one guide pipeline for medium passes at least through part of heat-transfer ribs 62a. ^ EFFECT: provision of compact heater meeting requirements of vehicle heating. ^ 10 cl, 5 dwg
