Beschreibung
Zusammenfassung:	A housing device for a traction battery with fluid-based cooling in a vehicle. The traction battery has a plurality of a battery cells. The housing device includes a housing body, which forms an enclosed interior with a plurality of receiving positions for receiving the plurality of battery cells and a bottom region of which is designed to receive liquid fluid. An evaporation device is included for evaporating the liquid fluid. The evaporation device has a plurality of microchannel structures for forming microchannels. The microchannel structures extend in a vertical direction in the assembled state and have, in their lower region with respect to the vertical direction, at least one inlet opening for receiving liquid fluid from the bottom region of the housing body. During operation, liquid fluid enters the microchannels through the at least one inlet opening and heat is transferred from the battery cells to the liquid fluid in the microchannels. The liquid fluid evaporates in the evaporation device. A traction battery for a vehicle with fluid-based cooling includes a housing device as described above.
