The invention relates to a device for pressing a cooler against a battery, said cooler having at least one cooling surface for absorbing or dissipating thermal energy, and the battery having at least one contact surface for the cooling surface of the cooler to rest on. The device comprises a pressure part having at least one spring-elastic pressure element for transmitting a contact pressure onto a section of the surface of the cooler facing away from the battery. The device further comprises at least one suspension unit for suspending the pressure part on the battery, said suspension unit being designed such as to generate a suspension force which is counter to the contact force when the cooler is arranged on the battery and the suspension unit is suspended on the battery.

The invention relates to a cooler arrangement for a drive train (21) in a motor vehicle (23). Said cooler arrangement comprises a first coolant circuit (3) with a first coolant cooler (7) as well as a second coolant circuit (5) with a second coolant cooler (9). The invention is characterized in that there is a connection between the first coolant circuit (3) and the second coolant circuit (5).
摘要:
The invention relates to a plate-shaped heat exchanger for a cooling device comprising at least one heat exchanger package, in particular for a motor vehicle, consisting of a plurality of openings for accommodating a pipe conducting a coolant, wherein each opening is surrounded by an passage and a plurality of projections are distributed between the passages for the heat exchange with the medium to be cooled. In order to allow a high performance increase of a cooling device, yet a low increase in pressure loss of the charge air, a plurality of projections are arranged around an passage, wherein the projections have a shape that assures deliberate heat conduction from the projections to the passage.

The invention relates to a heat exchanger (or a motor vehicle, comprising a first flow path (1) with a number of flow conduits (6) for conducting a fluid to be cooled, a deflection region (13), situated downstream of the first flow path (1) and a second flow path (2), situated downstream ol the deflection region (13). According to the invention, the flow conduits (6) of the first flow path (1) continue in the deflection region (13) and the second (low path (2) as continuous separate flow conduits (6). The invention also relates to a flow conduit (41, 41′, 61, 61′, 71, 71′, 81, 81′, 91, 91′) for a heat exchanger (30,40) for exchanging heat between a first fluid (31) and a second fluid (33). The aim of the invention is to guarantee an improved transfer of heat with a simultaneous acceptable pressure drop, whilst reducing the blocking risk.
