Heat exchanger

Abstract

Abstract The invention relates to a heat exchanger with heat exchanger pipes (3) which run between two chambers (2,4) and which are flowed through by a fluid (F1) and flowed against by another fluid (F2), and with an overflow pipe (5) through which a changeable partial flow of the fluid (F1) can be guided to avoid the heat exchange. The overflow pipe (5) is provided with a valve arrangement for the modification of its flow cross-section. This valve arrangement comprises a valve disc (6), which closes the overflow pipe (5) in one end position of the valve arrangement, and a valve ring (8) which is flowed through by the fluid (F1) leaving the overflow pipe (5) and, in the other end position of the valve arrangement, closes an outlet opening (9) for the fluid (F1) issuing from the heat exchanger pipes (3). In order to guarantee a low-loss and intensive mixing of the partial flows of the fluid (F1) with greatly reduced space requirement for the mixing section, the outlet opening (9) is formed in a collecting cone (10) which interacts with the valve ring (8). The valve ring (8) is provided with a conical outlet area (8a) which is provided with a great number of penetration openings (8b) and the inclination of which to the longitudinal axis of the heat exchanger corresponds approximately to the inclination of the collecting cone (10). <IMAGE>
