Abstract:
1. An electronics compartment comprising: a component space which is sealed off from a surrounding environment by walls of the electronics compartment; an internal panel arranged in the component space along a wall of the electronics compartment for delimiting an internal channel between the wall and the internal panel; a first inlet in a vicinity of a first end of the internal channel for allowing air to enter the internal channel from a space located on an opposite side of the internal panel in relation to the internal channel; a first outlet in a vicinity of a second end of the internal channel for allowing air to exit from the internal channel to the space located on the opposite side of the internal panel in relation to the internal channel; an external panel arranged along the same wall of the electronics compartment as the internal panel, but outside of the component space, for delimiting an external channel between the wall and the external panel, the wall being air-tight, at least between the external channel and the internal channel, for separating the external channel from the internal channel by preventing airflow between these channels; a second inlet in a vicinity of a first end of the external channel for allowing air to enter the external channel from the surrounding environment of the electronics compartment; a second outlet in a vicinity of a second end of the external channel for allowing air to exit from the external channel to the surrounding environment of the electronics compartment; and wherein the wall between the internal channel and the external channel is provided with protrusions and recesses for increasing the surface area of the wall to improve transfer of heat from the internal channel to the external channel.
