Arrangement comprising sealing element and heat exchanger, in air channel

Abstract

Arrangement comprising a sealing element (12, 13, 14) and a heat exchanger (1), in an air channel (4), wherein the heat exchanger (1) has a plurality of pipes (2) which carry a first fluid and are defined in their end regions by collection vessels (3) and can have a second fluid flowing around them. The arrangement is characterised in that the air channel (4) has a first guide groove (6) on an inner surface (5), which guide groove is formed by a first web (7, 8) and a second web (8, 7), and a second guide groove (9) which is formed by a third web (10, 11) and a fourth web (11, 10), the third web (10, 11) and the fourth web (11, 10) being disposed between the first web (7, 8) and the second web (8, 7) and the sealing element (12, 13, 14) enveloping the heat exchanger (1) along the collecting vessels (3) and its short sides.

Description

technical field [0001] The invention relates to a device in an air channel comprising a sealing element and a heat exchanger, wherein the heat exchanger has a plurality of tubes leading a first fluid, which tubes are delimited in their end regions by a collecting tank and Can be bypassed by a second fluid. Furthermore, the invention relates to a device located in the air duct of an air conditioning system. Background technique [0002] Heat exchangers, such as evaporators or heaters in air-conditioning systems used in motor vehicles, are usually arranged in the air duct of the air-conditioning system. Inside them, they are flowed through by a cooling medium. Air is usually used as the medium for the flow around the heat exchanger from the outside. [0003] When as much air as possible flows through the mesh made of tubes and corrugated fins, and only as little air as possible is outside from next to the heat exchanger, especially between the inner surface of the air chann...

Problems solved by technology

[0004] The disadvantage of using foam, especially macrocellular foam, is the potential for odor, which may be caused by dirt and bacteria clinging to the foam

[0005] In particular, the disadvantages of using rigid plastic parts are the high degree of complexity brought about by the precise dimensional construction of the sealing elements, and the possibility of creating acoustic bridges between the heat exchanger and the air channel due to direct contact, causing disturbances in the transmission of noise
