  • Patent number: 10969835
    Abstract: The invention relates to a cooling arrangement, in particular for a computer system, including at least one fan for generating a cooling air stream. The cooling arrangement further includes at least one first element to be cooled arranged in a first region and at least one second element to be cooled arranged in a second region. Furthermore, the cooling arrangement includes an air guide element formed with an internal isolation channel. The air guide element is formed in such a way as to divide the cooling air stream into a first air stream through the first region and a second air stream through the second region and to at least partially isolate the first air stream from the second air stream by the air guide element. Furthermore, the invention relates to an air guide shroud which is suitable for such a cooling arrangement.

  • Patent number: 9916870
    Abstract: The invention relates to an assembly for securing a slide-in unit in a mounting cage of a computer system. The mounting cage has a first side panel and a second side panel opposite the first side panel. The first side panel has at least one engagement element for engaging into a lateral fastening opening of the slide-in unit. The first side panel and the second side panel are arranged at a distance to one another such that the slide-in unit can be inserted into the mounting cage past the engagement element. After the insertion, a fastening element secured to the second side panel cooperates with the slide-in unit in such a way that the slide-in unit is pushed in the direction of the first side panel and the engagement element engages in the respective lateral fastening opening of the slide-in unit.
