ABSTRACT:
The present invention relates to a cooling device for an electronic apparatus comprising: a cooling element to be connected to an electronic component for receiving the heat load generated by the electronic component, an inlet port, an outlet port and a fan for bringing air to flow from the inlet port via the cooling element to the outlet port to cool the cooling element by means of the air flow. In order to achieve a simple device improving the reliability the cooling device comprises at least one return channel, through which some of the air flowing from the cooling element towards the outlet port is conducted to an electronic space to cool the electronic space, and that a forepart of the return channel is arranged in a place where the air flow from the cooling element towards the outlet port is colder than the air flowing from the cooling element on average. The invention also relates to a cooling method.
