Abstract

The present invention relates to a fan frame for a plurality of fan modules, particularly for a radiator of a motor vehicle, comprising a first fan holder having a first outflow region, at least one further fan holder having a further outflow region, and an intermediate region that connects adjoining edge regions of the first and the further fan holders to each other. The fan frame is characterised in that a shielding device, which separates the first and a further outflow region from each other, is provided in the intermediate region. The present invention further relates to a fan module, particularly having such a fan frame.

First claim

The invention claimed is:

1. A fan frame for a plurality of fan modules,
comprising a first fan bracket, which has a first outflow region,
comprising at least one additional fan bracket, which has an additional outflow region,
comprising an intermediate region, which continually interconnects adjacent edge regions of the first and the additional fan brackets,
wherein a shielding device is provided in the intermediate region and separates the first outflow region and the additional outflow region from each other, wherein the shielding device is designed as a partition portion which is integrally formed with the fan frame and arranged between two attachment struts of the first or additional fan bracket, wherein the partition portion extends up to 70% to 100% of an axial height of the attachment struts, and wherein the partition portion extends around at least one of the first and additional fan brackets in the intermediate region over an angular segment from 10°-135°.

2. The fan frame of claim 1 , wherein
the partition portion has a profiled upper edge.

3. The fan frame of claim 1 , wherein
the partition portion extends around at least one of the fan brackets in the intermediate region over an angular segment of 30° to 60°.

4. The fan frame of claim 1 , wherein
the partition portion extends over a circumference of at least one of the brackets over an arc segment in the range of from 5 cm to 20 cm or in the range of from 8 cm to 15 cm or in the range of from 10 cm to 12 cm.

5. The fan frame of claim 1 , wherein
the partition portion extends over at least 50% of an axial height of the attachment struts.

6. The fan frame of claim 1 , wherein
the fan frame is designed as a plastics injection-moulded part.

7. The fan frame of claim 1 , wherein the fan frame is designed to be used for a radiator of a motor vehicle.

8. A fan module for a radiator of a motor vehicle,
comprising a fan frame comprising a first fan bracket, at least one additional fan bracket, and an intermediate region of the fan frame, which continually separates the first fan bracket from the at least one additional fan bracket,
comprising a first fan which is mounted in the fan frame and is designed to generate a first air flow,
comprising at least one additional fan which is mounted in the fan frame, is designed to generate an additional air flow and is arranged and mounted in the fan frame beside the first fan,
wherein a shielding device is provided in the intermediate region of the fan frame between the first and the additional fan in respective outflow regions of at least one of the first and the additional fan in order to separate the first air flow from the additional air flow, wherein the shielding device is designed as a partition portion which is integrally formed with the fan frame and arranged between two attachment struts of the first or additional fan bracket, wherein the partition portion extends up to 70% to 100% of an axial height of the attachment struts, and wherein the partition portion extends around at least one of the first and additional fan brackets in the intermediate region over an angular segment from 10°-135°.

9. The fan module of claim 8 , wherein
the first fan bracket has a first outflow region;
the least one additional fan bracket having the respective additional outflow region; and
the intermediate region interconnects adjacent edge regions of the first and the additional fan brackets,
wherein the shielding device is provided in the intermediate region and separates the first outflow region and the respective additional outflow region from each other.

10. The fan module of claim 8 , wherein
the partition portion extends in the outflow direction of the first or the additional air flow.

11. The fan module of claim 8 , wherein
the first fan has a greater diameter than the additional fan.

12. The fan module of claim 8 , wherein
the first fan has at least one of a higher driving power and a higher air output than the additional fan.

13. The fan module of claim 8 , wherein the fan module is designed as a double fan module.
