Embodiment Construction

[0019] exist figure 1 The cooling system schematically shown in the present invention for ensuring the optimal operating temperature of a plurality of components 13, 14, 15 of an electric vehicle comprises a first cooling circuit 5, a second cooling circuit 6 and a bypass circuit 7, Their coolant flow can be switched on and off via the valve arrangement 4 . The valve arrangement 4 includes three valves 1 , 2 , 3 , each of which is assigned to a cooling or bypass line. It is thus possible to switch the cooling line on or off depending on the switching state of the valves 1 , 2 , 3 of the valve arrangement 4 . The bypass line 7 enables a bypass of the cooling device 8 arranged in the first cooling line 5 , so that a warmer coolant flow than the coolant flow of the first cooling line 5 can be connected via the bypass line 7 . In order to optionally additionally heat the coolant, the heating element 10 can also be arranged in the bypass line 7 . In order to feed the connected c...

Abstract

The invention relates to a thermal management module for the demand-oriented distribution of a coolant flow in an electric vehicle with a valve arrangement (4) comprising a plurality of valves (1, 2, 3). According to the invention there are provided a first valve (1) for switching the first cooling line (5), a second valve (2) for switching the second cooling line (6) and a third valve for switching the bypass line (7). A valve (3), wherein the bypass line (7) enables a bypass of the cooling device (8) arranged in the first cooling line (5). Furthermore, the invention relates to a cooling system for an electric vehicle with such a thermal management module.

Description

technical field [0001] The invention relates to a thermal management module for demand-oriented distribution of a coolant flow in an electric vehicle with a valve arrangement comprising a plurality of valves. Furthermore, the invention relates to a cooling system for an electric vehicle with a thermal management module for a demand-oriented distribution of a coolant flow to a plurality of connected components. Background technique [0002] Different electric vehicles are currently in development. They include components such as, for example, battery modules, power electronics and / or electric motors, which must be brought to and / or kept at operating temperature in order to ensure optimum function. In this case, different components can have different optimum operating temperatures. In order to meet these requirements, electric vehicles therefore usually have several independent cooling systems or a central cooling system, wherein, but in the last-mentioned case, the expecte...
