1. A cooling device for cooling components (101), the cooling device comprising:
a baseplate (2) which can be connected in a heat-conducting manner to a component (101) to be cooled,
a deflection region (3) including a first plate (3a) and a second plate (3b),
an intermediate region (4) between the baseplate (2) and the deflection region (3), and
a cooling element (5), which has a meandering configuration and has a plurality of central segments (51) and a plurality of deflection segments (52),
wherein the central segments (51) each extend from the baseplate (2) to the deflection region (3),
wherein the deflection segments (52) each create a reversal of direction within the baseplate (2) and within the deflection region (3) and connect two respective central segments (51) to one another,
wherein the central segments (51) extend through the second plate (3b),
wherein the first plate (3a) includes a groove in fluid communication with the central segments (51),
wherein the groove of the first plate (3a) is configured as a deflection channel (56) and is configured to connect two adjacent channels of the central channels (51),
wherein the cooling element (5) is filled with a working medium which is present simultaneously in a gaseous and a liquid state in the cooling element (5), and
wherein the central segments (51) have a multiplicity of channels (53),
wherein the first plate (3a) and the second plate (3b) are brazed to the central segments (51).
