ABSTRACT:
An air-conditioning system for a motor vehicle contains a heat exchanger with a heat-exchanger tube that features a profiled central channel and outer channels grouped around the central channel. This heat-exchanger tube is suitable for the construction of counterflow heat exchangers. For this purpose, the heat-exchanger tube is to be cut to corresponding lengths and provided with corresponding end pieces. Such heat exchangers have proven to be light, pressure resistant, and effective.
