Abstract: A tube plate for a heat exchanger has a base body in which at least two apertures are formed for receiving respectively a tube body. In addition, the tube plate includes a groove, likewise formed in the base body, with which the two apertures are connected with one another.

Abstract: A stacked-plate heat exchanger may include a high-temperature (HT) coolant circuit, a low-temperature (NT) coolant circuit, heat exchanger plates stacked upon one another and through which two coolants and a medium to be cooled may flow, and an obstruction configured to force a deflection of one of the coolants in the low-temperature coolant circuit. The two coolants may have different temperature levels in the high-temperature and low-temperature coolant circuits. The heat exchanger plates may include a partition wall separating the high-temperature and low-temperature coolant circuits from each other. The high-temperature and low-temperature coolant circuits may include a central HT coolant inlet and a central NT coolant outlet, respectively, adjacent to the partition wall and together forming a teardrop shape separated by the partition wall. The HT coolant inlet may have a part-circle-like shape and the NT coolant outlet may have a triangular shape, each having one side formed by the partition wall.

Abstract: A stacked-plate heat exchanger may include a high temperature coolant circuit having a first coolant flow therethrough, and a low-temperature coolant circuit having a second coolant flow therethrough, the first and second coolants having different temperature levels. The heat exchanger may also have heat exchanger plates stacked one on another, the first and second coolants flowing through the heat exchanger plates on one side, and a medium to be cooled flowing through the heat exchanger plates on another side. The heat exchanger plates may have an embossed partition separating the high-temperature coolant circuit and the low-temperature coolant circuit.

Abstract: In a system which comprises at least two log files L, data A,B,C,D is stored electively either in no log file, in a single log file or in both log files. By using parallel storage of selected data in a plurality of log files it is a simple matter to correlate the data in these log files with one another. It is possible to generate a plurality of different log files which fully satisfy different requirements on the contents of the log file in each case.
