HEATING DEVICE OF VEHICLE Russian patent published in 2019 - IPC B60H1/22 

FIELD: heating.

SUBSTANCE: invention relates to heating devices for a vehicle. Vehicle heating device includes housing (46) of heating device, which limits air flow space (47) for heated air and has inlet area (49) for air inlet into space (47) intended for air flow and area (51) for air outlet from air space (47) intended for air flow. In housing (46) of the heating device there is structural unit (30) of the combustion chamber, which is supplied with air required for combustion, and fuel. Besides, it includes heat exchanger area (11) with housing elongated in direction of longitudinal axis L and streamlined on outer side (24) passing in air space intended for air flow (47) by heat exchanger housing. On outer side (24) of housing (12) of heat exchanger are provided ribs (26) for heat transfer. Housing (46) of the heating device has circumferential wall (56) of the housing and area (58) of output of the end wall adjoining circumferential wall (56). Heat transfer ribs (26) have longitudinal edge (64) extending along circumferential wall (56) of housing and extending radial edge (66) extending along end wall outlet area (58). At one rib (26) for heat transfer by sections the distance of radial edge (66) from area (58) of end wall outlet from radially outside to radially inside is increased, preferably increases.

EFFECT: improved heat transfer capacity.
