  • the invention relates to a method and a device for dissipating heat in computer workstations according to the features of patent claims 1 and 3.
  • Computer workstations such as e.g. Stock exchanges typically include multiple computers and screens.

  • Heat load of several computers of a stock exchange workstation to prevent the environment or the space in which the computer workstation is located. This is achieved by keeping the air at least partially in a closed circuit to cool the load at the workplace. Another advantage is the low noise emission compared to conventional solutions.
