Abstract
A cooling device for cooling a traction battery of a vehicle by means of a fluid. The device includes an evaporation device for installing in a housing body of the traction body, at least one condensation device for installing on the vehicle outside of the housing body of the traction battery, and connection lines which conduct fluid evaporated in the evaporation device to the at least one condensation device and condensed fluid from the at least one condensation device back to the evaporation device. The evaporation device, the at least one condensation device, and the connection lines form a first cooling circuit. The first cooling circuit is designed in the form of a natural circulation. The circulation of the fluid through the first cooling circuit includes the process of transporting gaseous fluid from the evaporation device to the at least one condensation device and liquid fluid from the at least one condensation device back to the evaporation device, and during operation the circulation is carried out on the basis of a difference in the density of the fluid evaporated in the evaporation device and the fluid condensed in the at least one condensation device and on the basis of a difference in the height of the at least one condensation device and the evaporation device.
