    • To improve coolant sealing or reduce the risks in the event of leakage for an electronic unit, e.g. an engine control unit, containing electric and/or electronic components which are disposed on an upper side of a thermally conductive electronic base plate and thermally coupled to the base plate, the base plate in turn being thermally coupled to a coolant passage, there is provided a particular configuration and arrangement of the components delimiting a coolant passage. Advantageously, the underside of the base plate can come into direct contact with a coolant (“direct cooling”). By making a ridge running in an annularly closed manner and being formed in one-piece with the base plate, coolant escaping from the coolant passage is prevented from passing directly to the underside of the base plate. Accordingly, the coolant passage may be sealed by a “double sealing arrangement” on the underside of the base plate.
    • 改善冷却剂密封或降低电子单元泄漏时的风险,例如, 发动机控制单元,其包含设置在导热电子基板的上侧并且热耦合到所述基板的电和/或电子部件,所述基板依次与所述冷却剂通道热耦合, 限定冷却剂通道的部件的特定配置和布置。 有利地,底板的下侧可以与冷却剂(“直接冷却”)直接接触。 通过以环形关闭的方式制造脊并与基板成一体地形成,从冷却剂通道排出的冷却剂被防止直接通过到底板的下侧。 因此,冷却剂通道可以通过底板下侧的“双重密封装置”来密封。

    • The invention relates to a rotary/push-button controller having a controller ring (18) which can be rotated about a rotation axis (7) and is arranged such that it can rotate on a holding cylinder (6) which is arranged coaxially within the control ring (18). In this case, the holding cylinder (6) is provided at its end with an input and/or display field (14), and the control ring (18) and the holding cylinder (6) can be moved axially with respect to the rotation axis (7) against a spring force from a neutral position to a switch position which operates a switching element. The input and/or display field (14) is mounted so that it can rotate about the rotation axis (7). A rotary transmitter ring is arranged coaxially on the control ring (18) and is arranged coaxially alongside a rotary transmitter (17) which is firmly connected to the holding cylinder (6) with the relative rotation position of the rotary transmitter ring with the respect to the rotary transmitter (17) being recordable.
    • 本发明涉及一种旋转/按钮控制器,其具有可围绕旋转轴线(7)旋转的控制器环(18),并且被布置成使其能够在保持筒(6)上旋转,保持筒(6)同轴地布置在 控制环(18)。 在这种情况下,保持筒(6)在其端部设置有输入和/或显示区域(14),并且控制环(18)和保持筒(6)能够相对于旋转轴线 轴(7)抵抗从中性位置到操作开关元件的开关位置的弹簧力。 输入和/或显示区域(14)被安装成使得其可绕旋转轴线(7)旋转。 旋转发射器环同轴地布置在控制环(18)上并与旋转发射器(17)同轴地布置,旋转发射器(17)与旋转发射器环的相对旋转位置牢固地连接到保持筒(6),相对于 旋转发射器(17)可记录。
