Abstract
A device for administering medical liquid, in particular an infusion pump, and a system that includes the device and a holding device. The device includes a housing and a component that generates heat during use of the device. The component is arranged inside the housing. A passive heat sink is attached to an outer side of the housing and is connected thermally, in particular in a heat-conducting manner, to the component. The heat sink has cooling fins.
Claims14
A device for administering medical fluid, the device comprising:
- a housing;
- a component which is heat-generating at least when the device is in use and which is arranged inside the housing;
- and
- a heat sink that is passive, the heat sink being mounted on an outer side of the housing and connected to the component, the heat sink comprising:
- cooling ribs extending in a vertical direction, and
- a coupling portion comprising:
- a planar contact surface extending in the vertical direction, at a location in a lateral direction between at least two of the cooling ribs, and
- a rail extending perpendicularly away from the planar contact surface along a top of the planar contact surface in the vertical direction and along opposite lateral sides of the planar contact surface in a lateral direction, to define an inverted U-shaped wall.
