Abstract: The present invention relates to a cooling fin arrangement (1) of a cooler, through which fluid can flow, for cooling power electronics (200). The cooling fin arrangement (1) comprises at least one cooling fin (10), which is formed from a wave profile that periodically repeats in a direction of repetition (501), the direction of repetition (501) being perpendicular to a flow direction (500). The invention also relates to a cooler, through which fluid can flow, for cooling power electronics (200), the cooler comprising a cooling fin arrangement (1) of this type, and to a power electronic assembly (1000), comprising power electronics (200) and a cooler (100) of this type, through which fluid can flow.

Abstract: A power module, for power electronics of a vehicle, having two DC busbars and three phase busbars which are disposed between the two DC busbars, and a plurality of power semiconductors, each of which is disposed between one of the DC busbars and one of the phase busbars, and power electronics having at least one such power module, and a vehicle having such power electronics. The DC busbars and the phase busbars are electrically insulated from one another and in each case have at least one cooling duct through which a dielectric fluid flows, at both open ends each of the DC busbars and the phase busbars having at least one plug-in electrical contact connection and at least one plug-in fluid connection that in each case form a combined plug-in connection, so that multiple power modules are connectable to each other in fluid-tight fashion using plug connections.

Abstract: The invention relates to a cooling device (1) for cooling components (101), comprising a baseplate (2) which can be heat-conductively connected to a component (101) to be cooled, a deflection region (3), an intermediate region (4) between the baseplate (2) and the deflection region (3), and a cooling element (5), which is formed in a meandering shape and has multiple central segments (51) and multiple 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 change of direction within the baseplate (2) and within the deflection region (3) and connect two respective central segments (51) to one another, wherein the cooling element (5) is filled with a working material, which is simultaneously gaseous and liquid in the cooling element (5), and wherein the central segments (51) have a plurality of channels (53).

Abstract: An absorption chiller may include an absorbent circuit in which a liquid absorbent circulates and a working medium circuit in which a liquid working medium circulates. The absorbent circuit may include an absorber and a desorber. The working medium circuit may include an evaporator and a condenser. The absorption chiller may also include a low pressure membrane arrangement and a high pressure membrane arrangement each being permeable to a working medium vapour, impermeable to the liquid working medium and the liquid absorbent, and arranged between the evaporator and the absorber such that it is in contact with the working medium and the absorbent. At least one of the low pressure membrane arrangement and the high pressure membrane arrangement may include a working medium membrane and an absorbent membrane.

Abstract: In a data processing system and an operating method therefor, a medical text is automatically read into an evaluation unit of the data processing system, medical terms (in particular in abbreviated form) are automatically searched for in the medical text using a rule set stored in the data processing system, a term identified by means of the rule set is compared with Latin terms stored in a first databank, the identified term is compared with terms classified according to diagnosis criteria and stored in a second databank, and after evaluation of both databanks, the technical term is replaced by a corrected (completed) term.
