Fixing and protecting arrangement for a capacitor
View Patent ↗A fixing and protecting arrangement for a capacitor may include a cooling element, one or more recesses arranged in the cooling element, and a capacitor intended to be fixed into each recess. The capacitor may be arranged in the recess in such a way that a lower surface of the capacitor is in contact with the cooling element for transferring heat from the capacitor to the cooling element.
1. A fixing and protecting arrangement for a capacitor, comprising:
a capacitor, the capacitor including a lower surface, an upper surface and a longitudinal axis;
a cooling element;
a fixing member configured to fix the capacitor to the cooling element; and
at least one recess arranged in the cooling element, into which recess the capacitor is configured to be arranged in such a way that the lower surface of the capacitor is in contact with the cooling element to transfer heat from the capacitor to the cooling element;
wherein an adapter collar is arranged between the capacitor and the cooling element.
2. A fixing and protecting arrangement for a capacitor according to claim 1 , wherein the recess includes:
a deeper portion closer to an outer periphery thereof, to which a lower portion of the adapter collar is mountable, and an inner portion, to which the lower surface of the capacitor is mountable.
3. A fixing and protecting arrangement for a capacitor according to claim 1 , wherein the upper portion of the adapter collar is arranged to protrude to support the capacitor in a direction perpendicular to the longitudinal axis of the capacitor.
4. A fixing and protecting arrangement for a capacitor according to claim 1 , wherein the fixing member comprises a fixing plate that is arranged against the upper surface of the capacitor to direct forces at the capacitor in a direction of the longitudinal axis.
5. A fixing and protecting arrangement for a capacitor according to claim 4 , wherein the fixing plate comprises fixing members configured to fix the fixing plate to the cooling element.
6. A fixing and protecting arrangement for a capacitor according to claim 4 , wherein the fixing plate includes openings through which the capacitor is connectable.
7. A fixing and protecting arrangement for a capacitor according to claim 4 , wherein the fixing plate includes at least one fixing member configured to forces at a capacitor in the direction perpendicular to the longitudinal axis of the capacitor.
8. A fixing and protecting arrangement for a capacitor according to claim 1 , wherein an insulating film is arranged between the capacitor and the cooling element.
9. A fixing and protecting arrangement according to claim 1 , wherein heat-conducting paste is arranged between the capacitor and the cooling element.
10. A cooling element for receiving a capacitor, comprising:
at least one recess arranged in the cooling element, into which recess the capacitor is configured to be arranged in such a way that a lower surface of the capacitor is in contact with the cooling element to transfer heat from the capacitor to the cooling element;
wherein the recess includes:
a deeper portion closer to an outer periphery thereof, to which a lower portion of an adapter collar is mountable,
and an inner portion, to which the lower surface of the capacitor is mountable.
