Abstract
A converter cabinet includes walls within which a converter that includes a plurality of semiconductor switches and energy stores, a DC-link busbar system, a first heat sink for dissipating heat from the semiconductor switches, and a second heat sink for dissipating heat from the energy stores is arranged, wherein the first and the second heat sink are mechanically connected to one another, where the first and the second heat sinks are offset with respect to one another in a build direction of the converter, and computer program product include commands which, when executed by a computer, cause the computer to simulate an operating behavior of the converter in which a release of heat occurs.

-16. (canceled)
A converter, comprising:
- a plurality of semiconductor switches;
- at least one energy storage device;
- a DC-link busbar system;
- a first heat sink for dissipating heat from the plurality of semiconductor switches;
- and
- a second heat sink for dissipating heat from the at least one energy storage device;
- wherein at least one of the first and second heat sinks are liquid-cooled;
- wherein the first and second heat sinks are arranged offset from one another in a direction of assembly of the converter for dissipating heat from ambient air in an environment of the converter;
- wherein at least one of (i) the direction of assembly corresponds to the direction in which at least one semiconductor switch is mounted on the first heat sink and (ii) the at least one energy storage device is mounted on the second heat sink;
- and
- wherein the first heat sink is connected to the second heat sink via cooling fins.
A method for simulating an operating behavior of a converter comprising a plurality of semiconductor switches, at least one energy storage device, a DC-link busbar system, a first heat sink for dissipating heat from the plurality of semiconductor switches, and a second heat sink for dissipating heat from the at least one energy storage device, the method comprising:
- a) providing a dataset which is usable to simulate operation of at least part of the converter to be simulated;
- b) specifying at least one operating condition which characterizes the operating behavior to be simulated;
- c) executing a computer program product which is configured to simulate the operating behavior of the converter based on the data set and the at least one operating condition and to determine at least one operating parameter;
- and
- d) outputting the at least one operating parameter to at least one of a user and a data interface;
- wherein the at least one of the first and second heat sinks are liquid-cooled;
- wherein the first and second heat sinks are arranged offset from one another in a direction of assembly of the converter for dissipating heat from ambient air in an environment of the converter;
- wherein at least one of (i) the direction of assembly corresponds to the direction in which at least one semiconductor switch is mounted on the first heat sink and (ii) the at least one energy storage device is mounted on the second heat sink;
- and
- wherein the first heat sink is connected to the second heat sink via cooling fins.
The computer program product as claimed in claim 15, wherein the computer program product comprises a data interface which is configured to connect the computer program product to a sensor which is assigned to a corresponding physical converter.
