This ensures in any case that can be pushed forward by the pushing of a carriage 200 in the inlet region of a cooling bath 110 or 120 by means of the impact cylinder 600, 601 or 602, 603 a carriage 200 in the region of the exit of the cooling bath 110 or 120. If fewer cars are provided, the shock cylinders would have to be made longer accordingly.
  • the impact cylinders, the lift and the impact plates preferably comprise one or more hydraulic cylinders, but other drive means such as a pneumatic cylinder, a rack gear or the like may be provided.
  • the transfer carriages 320, 420 each comprise a drive. This can be designed as a cable, electric motor, hydraulic or pneumatic cylinder or in any other known to the expert manner.
  • any other locking systems can be provided.
  • two L-shaped opposite holding elements could each engage behind a strip of the frame 220.
  • the cooling device described here can not be used only for the cooling of green anodes. Rather, this device can be used for almost any body to be cooled, wherein the device of the size of the body to be cooled is adjusted accordingly. In particular, the size of the device can be easily, without departing from the idea underlying the invention, doubled, tripled, etc., but also be halved, divided in third, etc.
  • the apparatus can also be used for cooling, dyeing, cleaning, chemical treatment of parts such as a car body of a car and the like.
  • a device and a method are provided by means of which hot moldings can be cooled in a particularly efficient and economical manner.
