Evaporator, in Particular for an Air-Conditioning System of a Motor Vehicle

Abstract

The invention relates to an evaporator (1), in particular for an air-conditioning system of a motor vehicle, comprising flow channels for a coolant and ribs which can be impinged upon by air and which are arranged on the outside of the flow channels. According to the invention, at least one cooling element (5) which can be cross-flown by a coolant (5) is connected in a thermally conductive manner to the evaporator (1) and is connected to a secondary circuit (6) which acts as a cooler for the consumers, in particular electronic components (8).

Embodiment Construction

[0044]For the purposes of promoting an understanding of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications in the illustrated device and its use, and such further applications of the principles of the disclosure as illustrated therein being contemplated as would normally occur to one skilled in the art to which the disclosure relates.

[0045]FIG. 1 shows a double-row flat tube evaporator 1, which is connected on the refrigerant side to a refrigerant circuit 2 of a not-shown motor vehicle air-conditioning system. In addition to the evaporator 1, there is a condenser 3 and a compressor in the refrigerant circuit. The evaporator 1 corresponds in its construction essentially to the state of the art mentioned above (DE 198 26 881 A1 by the applicant...
