Abstract: A method for operating a cooling unit that contains a slightly inflammable refrigerant is provided. The method is used with refrigerant circuit containing the slightly inflammable refrigerant and at least two shut-off devices that can be controlled by a computer, in which the computer closes the at least two shut-off devices thus dividing the refrigerant circuit into at least two separate segments when the cooling unit is switched off.

Abstract: A stacked disc heat exchanger for a thermal management module may include a plurality of stacked discs arranged following one another in a stacking direction. Each stacked disc of the plurality of stacked discs may include a bottom extending transversely to the stacking direction. An outermost disc of the plurality of stacked discs in the stacking direction defining a cover disc. The cover disc may include at least one convexity formed in the stacking direction towards an outside. The at least one convexity may extend transversely to the stacking direction and may form a channel for a flow path extending through the stacked disc heat exchanger of a fluid. The cover disc may further include at least one opening that is open in the stacking direction towards the outside for fluidic connection with the thermal management module.

Abstract: A method for manufacturing a distributor for refrigerant in components in a thermal management module is provided, distributor has distributor openings for the refrigerant on an upper surface and/or a lower surface that faces away from the upper surface. Greater reliability, reduced installation space, and greater variability in the shape of the distributor are obtained in that the distributor is produced in a casting process, in which channel sections of channels passing through the distributor are obtained with a removable core in a mold. A method for manufacturing a thermal management module that contains such a distributor, as well as a distributor produced in this manner, and a thermal management module is provided.

Abstract: A thermal management module for a thermal management system is disclosed. The thermal management module includes a first heat exchanger for flowing through by a refrigerant and by a working medium fluidically separately with respect to the refrigerant. A second heat exchanger is provided including at least a first fluid path and at least a second fluid path, separate from the first fluid path, respectively for flowing through by the refrigerant. A connecting arrangement is arranged between the first heat exchanger and the second heat exchanger. The connecting arrangement connects the first heat exchanger and the second heat exchanger to one another mechanically and fluidically, so that the refrigerant can flow between the first heat exchanger and the second heat exchanger.
