    摘要： A cooling element (1; 10; 100), comprising a body (2) having a first surface (21) adapted to receive a heat source and a second surface (22) provided with protrusions (3; 30) for forwarding a heat load received from the heat source via the first surface (21), and a gap (4; 40) arranged between the protrusions (3; 30). The protrusion (3; 30) at least partially narrows in the direction towards the body (2), wherein the gap (4; 40) at least partially narrows in the direction away from the body (2).

    摘要： The present invention relates to a system (10) for monitoring a switchgear, the system comprising:
    - at least one temperature sensor (20);
    - a processing unit (30); and
    - an output unit (40).
    The at least one temperature sensor is configured to acquire temperature data for each location of at least one location of a switchgear (50) at n time points. The at least one temperature sensor is configured to provide the temperature data to the processing unit. The processing unit is configured to determine n-1 rates of change of temperature for one or more locations of the at least one location with respect to the n temperature data for the one or more locations at the n time points. The processing unit is configured to determine a state of the switchgear, wherein the determination of the state of the switchgear comprises utilization of the n-1 rates of change of temperature for the one or more locations and at least n-1 of the n temperature data for the one or more locations. The output unit is configured to output the determined state of the switchgear when the determined state of the switchgear is determined not to be normal or not to be healthy.
