Abstract:
1. A cooling element of an electronic device, comprising: an inlet opening for receiving cooling fluid, an outlet opening for discharging cooling fluid from the cooling element, and a flow channel for directing cooling fluid from the cooling element inlet opening to the outlet opening, wherein the flow channel comprises a section with a smaller cross-section as compared to the cross-section of other parts of the flow channel in order to generate a pressure difference between a forward end and a tail end of the flow channel, at the higher-pressure forward end of the cooling element flow channel and before said section with a smaller cross-section in the direction of flow, an inlet opening is arranged for a secondary cycle, from which cooling fluid is directed to a secondary cycle that is external to the cooling element, and at the lower-pressure tail end of the cooling element flow channel and after said section with a smaller cross-section in the direction of flow, an outlet opening is arranged for said secondary cycle, from which cooling fluid returning from the secondary cycle is directed to the flow channel of the cooling element.
