FLOW CONTROL INSERT, FASTENING ELEMENT, FLOW CONTROL SYSTEM AND HEATING DEVICE Russian patent published in 2023 - IPC F23D3/40 

FIELD: mobile heating devices.

SUBSTANCE: flow control insert (130, 131, 132, 133, 134, 135, 136) for a evaporative burner heating device, where the evaporative burner includes a blower chamber or combustion air prechamber, an evaporator seat, and a combustion chamber. The evaporator housing has a bottom wall and a peripheral wall with at least two combustion air through holes for directing combustion air from the blower chamber or combustion air prechamber generally along the outside of the evaporator housing through the combustion air through holes. for peripheral wall burning into the combustion chamber. The flow control insert (130, 131, 132, 133, 134, 135, 136) includes at least one first area (28a, 130a, 131a, 132a, 133a, 134a, 135a, 136a) overlapping at least one of through holes for combustion air, and a second area for mounting in the blower chamber or combustion air prechamber of the evaporative burner, the first area having the shape of a tongue. The second area for fastening to the evaporator socket is located in the region of the lower wall of the evaporator socket, or the second area includes support elements for support on the supercharger housing. The first area (130a, 131a, 132a, 133a, 134a, 135a, 136a) includes a protrusion or convexity (130c, 131c, 132c, 133c, 134c, 135c, 136c) located in the area of the occluded through holes for combustion air or in the direction flow after the blocked through holes for combustion air to create support relative to the peripheral wall.

EFFECT: optimized noise spectrum of a heating device at a late stage of development.
