Abstract
The invention relates to a blower (99), in particular for an engine cooling blower in a motor vehicle, comprising a housing (10) having a cooling air guide device (200), wherein the housing (10) is designed for mounting a drive unit (102, 103) and the cooling air guide device (200) in the motor vehicle, and for guiding a cooling air flow (20, 30, 31, 32) to the drive unit (102, 103), wherein the cooling air guide device (200) is designed as one piece with the housing (10).
Claims13
A fan unit (99) for an engine cooling fan, the fan unit comprising a housing (10;
- 90) with a cooling air flow device (200;
- 201), wherein the housing (10;
- 90) is designed to secure a drive unit (102;
- 103) and the cooling air flow device (200;
- 201) and to direct a cooling air flow (20, 30, 31, 32) at the drive unit (102, 103), characterized in that the cooling air flow device (200;
- 201) is integral with the housing (10;
- 90) and comprises at least one cooling fin (2) and a deflecting mechanism (3), wherein the cooling fin (2) is designed to determine a longitudinal direction of the cooling air flow (20, 30, 31, 32), and the deflecting mechanism (3) is designed to determine a transverse, radially inwardly direction of the cooling air flow (20, 30, 31, 32), wherein the cooling fin (2) is integral with the deflecting mechanism (3), wherein the cooling fin (2) includes a horizontal cooling fin section (21) disposed along a top surface (91) of the housing (10), and a vertical cooling fin section (40) that extends radially outwardly from the housing (10), and wherein the deflecting mechanism (3) deflects and redirects the cooling air flow (20, 30, 31, 32) so as to cause the air flow (20, 30, 31, 32) to move in the transverse direction.
A fan unit (99) for an engine cooling fan, the fan unit comprising a housing (10;
- 90) with a cooling air flow device (200;
- 201), wherein the housing (10;
- 90) is designed to secure a drive unit (102;
- 103) and the cooling air flow device (200;
- 201) and to direct a cooling air flow (20, 30, 31, 32) at the drive unit (102, 103), characterized in that the cooling air flow device (200;
- 201) is integral with the housing (10;
- 90) and comprises at least one cooling fin (2) and a deflecting mechanism (3), wherein the cooling fin (2) is designed to determine a longitudinal direction of the cooling air flow (20, 30, 31, 32), and the deflecting mechanism (3) is designed to determine a transverse direction of the cooling air flow (20, 30, 31, 32), wherein the cooling fin (2) is non-planar, and is integral with the deflecting mechanism (3), characterized in that the cooling fin (2) comprises a horizontal cooling fin section (21) disposed along a top surface (91) of the housing (10), and a vertical cooling fin section (40) that extends radially outwardly from the housing (10), wherein the cooling fin (2) provides the cooling air flow (20, 30, 31, 32) with a swirl effect as the cooling air passes radially inwardly.
