Abstract
An assembly having an intake connector with an air entrance for an air-conditioning system and a filter element having a concertina bellows having peripheral troughs and peripheral peaks, wherein the filter element has a water-repellent filter medium and wherein the filter element at least partially covers the air entrance, suitable for discharging snow and water, in particular snowmelt, to avoid flow into the air-conditioning system of a motor vehicle and to minimize damage to a filter element, wherein the concertina bellows is disposed so as to be inclined at an angle of 5° to 90°, preferably at an angle of 15° to 85°, in relation to the horizontal, wherein the filter element has an outflow unit for a water outflow from the peripheral troughs.
Claims20
An assembly, comprising:
- an intake connector including an air entrance for an air-conditioning system;
- a filter element including a concertina bellows, wherein the concertina bellows includes peripheral troughs at a bottom of the bellows and peripheral peaks at a top of the bellows with fold edges running on each side of the bellows so as to follow a zigzag line or an undulated line, the top and bottom of the concertina bellows being inclined at an angle of 5° to 90°, in relation to the horizontal,
- an edge strip disposed over the fold edges on at least one side of the concertina bellows such that water can flow out from at least one of the peripheral troughs,
- wherein the filter element includes a water-repellent filter medium,
- wherein the filter element at least partially covers the air entrance,
- and
- wherein the filter element includes an outflow unit configured for a water outflow from the at least one peripheral trough.
A supply air filter of an air-conditioning system, comprising:
- a filter element including a concertina bellows including peripheral troughs and peripheral peaks,
- wherein the filter element includes a water-repellent filter medium,
- wherein the filter element includes an outflow unit for a water outflow from the peripheral troughs,
- wherein fold edges run in each case on one side of the concertina bellows so as to follow a zigzag line or an undulated line,
- wherein the fold edges on at least one side of the concertina bellows are bordered by an edge strip,
- wherein the edge strip is disposed or configured on the fold edges such that water can flow out from at least one peripheral trough,
- wherein a channel, which is not closed off by the edge strip, is configured on a base of at least one peripheral trough, and
- wherein the outflow unit is configured as V-shaped openings.
A method filtering supply air of an air-conditioning system, the method comprising:
- contacting the supply air with a filter element, the filter element including
- a concertina bellows including peripheral troughs and peripheral peaks,
- a water-repellent filter medium, and
- an outflow unit for a water outflow from the peripheral troughs,
- wherein fold edges run in each case on one side of the concertina bellows so as to follow a zigzag line or an undulated line,
- wherein the fold edges on at least one side of the concertina bellows are bordered by an edge strip,
- wherein the edge strip is disposed or configured on the fold edges such that water can flow out from at least one peripheral trough,
- wherein a channel, which is not closed off by the edge strip, is configured on a base of at least one peripheral trough, and
- wherein the outflow unit is configured as V-shaped openings.
