The present invention relates to a cooling element of an electronic device, comprising: an inlet opening, and outlet opening, and a flow channel. To achieve efficient cooling with as low costs as possible, the flow channel is designed to cause a pressure difference between the forward end and tail end of the flow channel. At the higher-pressure forward end, an inlet opening is arranged for a secondary cycle. At the lower-pressure tail end of the cooling element flow channel, an outlet opening is arranged for said secondary cycle.
