AIR BLOWER UNIT Russian patent published in 2015 - IPC F24F13/06 

FIELD: heating.

SUBSTANCE: this invention relates to air blower units that can supply a uniform air flow. An air blower unit includes an equalising device that is located on the way of the flow and converts it to a uniform air flow intended to be supplied to the next side of the equalising device in the flow direction; front and rear direction, direction as to width and vertical direction; an air-permeable front surface formed on the next side of the equalising device in the flow direction and having the first ventilation holes distributed in the direction as to width and in vertical direction, and side surfaces passing to the previous side in the flow direction from side edges of the air-permeable front surface, which are located in the corresponding side parts of the air-permeable front surface in the direction as to width and which pass in vertical direction; with that, the second ventilation holes are distributed at least on one of the side surfaces opposite to each other in direction as to width; with that, the second ventilation holes have a possibility of blowing out some part of the air that passed through the equalising device outwards in the direction as to width. The air blower unit includes many devices equalised in the direction as to width, and the second ventilation holes have a possibility of blowing out some part of the air that passed through the equalising device towards the side surfaces of the adjacent device out of the specified variety of devices. This allows at equalisation of air blower units relative to each other in horizontal and/or vertical direction supplying a uniform air flow or a non-uniform flow of fresh air between the corresponding devices and to the next side in the flow direction.

EFFECT: supply of a uniform air flow.
