Abstract
A heat exchanger for a spacecraft utilizes a droplet radiator, whereby the droplet collector has the shape of a rotation symmetrical ring body that is rotatable about a central rotational axis. Preferably, the rotation symmetric ring body has the shape of a wheel, whereby the droplet generator is arranged near the rotational axis of symmetry and the collector forms a wheel rim. The return flow of the coolant takes place either through the spokes of the wheel which connect the droplet collector wheel rim to the hub or through a separate suction conduit. A secondary coolant flow circuit may be integrated into the droplet collector.
