Heat exchanger device

Abstract

The invention relates to a heat exchanger arrangement having at least one first heat exchanger and having a second heat exchanger, the first heat exchanger having a first heat exchanger matrix with a first air inlet surface and a first air outlet surface, and the second heat exchanger having a second heat exchanger matrix with a second air outlet surface, the first heat exchanger is provided with a first air inlet face and a second air outlet face, the first heat exchanger and the second heat exchanger are adjacently arranged, so that the first air outlet face and the second air inlet face are oppositely arranged, and the two heat exchangers are continuously arranged in the main air flowing direction; at least one sealing strip is arranged on at least one side region of the two heat exchangers or on the two side regions of the heat exchangers, the sealing strip produces a lateral sealing effect between the first heat exchanger and the second heat exchanger, and the sealing strip is an injection-molded sealing strip having an injection-molded hard component. And a soft component is injection-molded on the hard component.

Description

technical field [0001] The invention relates to a heat exchanger arrangement, in particular for a motor vehicle. Background technique [0002] Heat exchangers are used in a variety of ways in motor vehicles. In this connection, a heat exchanger arrangement is also known having a plurality of heat exchangers which are arranged in series in the front of the motor vehicle. The heat exchangers arranged in this way are successively passed through by the air flow to the motor vehicle at higher driving speeds, so that a heat transfer takes place between the air and the fluid flowing through the corresponding heat exchanger. Due to the high air flow at high driving speeds, possible side leakage air flows between the heat exchangers are only slightly damaging, although this means that only a small air flow is available for the rear mounted heat exchanger used. If, on the other hand, the ventilator is switched on at low driving speeds or when the motor vehicle is parked, the ventil...

AI Technical Summary

Problems solved by technology

If, on the other hand, the ventilator is switched on at low driving speeds or when the motor vehicle is parked, the ventilator draws in an air flow through the heat exchanger, wherein possible side leakage air flows past the heat exchanger flow is considered disruptive as this results in adverse effects on cooling with reduced air flow

[0003] The use of known foam strips for sealing between heat exchangers has the disadvantage that these foam strips deteriorate very quickly and can no longer perform their function, and that they only perform an insufficient seal
