    • A cabinet for electric and electronic systems, in particular a switchboard cabinet, has a functional chamber closed in a dust- and water-tight manner and at least one door that closes the chamber in a dust- and water-tight manner. The switchboard cabinet is characterised in that a structure composed of several shells is provided around the functional chamber (1). This structure consists of baffles (11), the wall (2) of the functional chamber and an outer casing (5). An inner, channel-shaped space (6) extends between the baffles (11) and the wall (2) of the functional chamber. An outer, channel-shaped space (6') extends between the wall (2) of the functional chamber and the outer wall (5). Controllable, load-dependable mass flows may be independently applied to the two channel-shaped spaces (6, 6'). The mass flows may be adjusted in a range from 0 to a maximum value. The maximum value is determined on the one hand by the hydraulic resistance of the elements (12, 7, 6') and the characteristic curve of the ventilator (8') and on the other hand by the hydraulic resistance of the equipment in the functional chamber and of the inner channel-shaped space (6), and by the characteristic curve of the ventilator (8). Heat transport from the functional chamber (1) to the environment or from the environment to the functional chamber (1) may thus be intensified and/or limited. This cabinet has in particular good cooling properties and offers with simple technical means an improved thermal protection of the functional chamber depending on the conditions of use.

    • 用于电气和电子系统,特别是配电柜的机柜具有以防尘和防水方式关闭的功能室和至少一个以灰尘和水密方式关闭室的门。 配电盘柜的特征在于,在功能室(1)的周围设有由多个壳体构成的结构。 该结构由挡板(11),功能室的壁(2)和外壳(5)组成。 内部的通道形空间(6)在挡板(11)和功能室的壁(2)之间延伸。 外部的通道形空间(6')在功能室的壁(2)和外壁(5)之间延伸。 可控的负载可靠的质量流量可以独立地应用于两个通道形空间(6,6')。 质量流量可以在从0到最大值的范围内调整。 最大值一方面由元件(12,7,6')的液压阻力和通风器(8')的特性曲线确定,另一方面由设备在功能上的液压阻力 腔室和内部通道形空间(6)以及通风机(8)的特性曲线。 因此可以加强从功能室(1)到环境或从环境到功能室(1)的热量传输和/或限制。 该机柜特别具有良好的冷却性能,并且具有简单的技术手段,根据使用条件改善了功能腔的热保护。
