The invention relates to a device for controlling the temperature of objects, in particular for drying coated vehicle bodies or body parts, the device having a housing and a temperature controlling tunnel accommodated into the housing. A temperature controlling device for controlling the temperature of the objects using a temperature-controlled gaseous fluid comprises fluid nozzles, through each of which a jet of fluid can be dispensed onto the objects. A tunnel atmosphere can be suctioned through at least one suction opening using a suction system, whereby a base current is generated in the direction of the at least one suction opening in the temperature controlling tunnel. A convection device is provided, by means of which a convection current can be generated in addition to the base current, said convection current supporting the base current.
