  • a particular closed fluid guide for guiding the tempering in the device and between the device and a consumer.
  • thermostats serve, for example, to heat a consumer, for example a reactor in a chemical operation, to a certain temperature, to hold it for a predetermined time at this temperature and to cool it again after this time. It is not only important to comply with the specified temperatures exactly, but also to achieve these quickly and to cool down again quickly.
  • the best known devices can cover a temperature range of -120 ° C to + 400 ° C. In these devices, the circulating in the fluid guide temperature control fluid is heated with the heater or cooled with the cooling device and fed to a connected to the fluid guide consumers and then returned from this to the device.
  • the schematic in Fig. 6 shown known temperature control device 1 has a helical heater 3 and a first evaporator 5 of a refrigeration cycle 7.

  • the temperature control fluid guided through the fluid guide 21 by means of the impeller 15 thus flows through the evaporator 5, where it is cooled when the evaporator 5 is operated, and the heating device 3, where it is heated when the heating device 3 is operated.
  • the sleeve and the shaft 17 have a certain length outside of the cylinder 13. In addition, they are as thin as possible in order to conduct as little heat in the direction of the drive 19.
  • a seal located between the sleeve and the shaft 17 is a seal (not shown).
  • the bulkhead 27 is disposed at a smooth rotated position of the sleeve, so that a good heat transfer between the sleeve and the bulkhead 27 results.

  • the first evaporator 5 is formed as a heat exchanger.
  • the second evaporator 11 is a so-called suction gas cooler. Through this flows out of the compressor 9 exiting cold refrigerant. Warm refrigerant returned from the first evaporator 5 to the compressor 9 flows around the second evaporator 11 and is thereby cooled.
  • the second evaporator 11 therefore acts as a heat exchanger between the cold refrigerant and the hot refrigerant, so that the compressor 9 is already supplied pre-cooled refrigerant.
  • the known temperature control device 1 requires a relatively large amount of space.
  • the US 2005/0269067 A1 discloses a device according to the preamble of claim 1.

  • the heating device and the cooling device can be arranged nested in one another in a particularly compact manner.
  • a circulation device is arranged in the fluid guide.
  • the circulation device is an impeller which is rotatably arranged in the fluid guide, so that by a rotational movement of the Impeller, the tempering fluid can be circulated in the fluid guide.
  • the circulation device is designed so that it sets the tempering fluid in the container in rotation, and means are provided, through which the rotating tempering in the winding direction between the turns of the container arranged in the heating and / or cooling device ,
  • the rotational movement of the tempering fluid caused by the circulation device is therefore utilized to guide the tempering fluid between the turns of the heating and / or cooling device, so that the turns are particularly well, in particular laminar, flowing around the rotating fluid, whereby the tempering fluid is particularly effective is heated or cooled.
  • the circulation device is likewise arranged in the common container for the heating device and the cooling device. This saves additional space.
  • the tempering fluid flows in the vertical direction in the region of the heating device and the cooling device. This allows gravity to be used for the circulation. In addition, a venting of the fluid guide is facilitated.
  • the container may be formed as a cylinder with vertical cylinder axis in use. This results in good flow conditions, in particular in conjunction with a pump with a vertical axis of rotation.
  • the container has a first, outer tube of a container insert.

  • the outer tube may be formed as an overflow tube and the tempering fluid can be supplied via a flow to one of the two annular spaces and reach by overflow into the other annulus. In a simple way, such a flow through both annular spaces can be realized one after the other.
  • the inner tube rests on the bottom of the container and has the outer tube to the container bottom at a distance. Furthermore, the inner annular space is closed by a plate down and the outer annular space at the lower end has a connection to the return line of the fluid line.
  • a clever fluid management is realized in a simple manner. The fluid returning via the return from a consumer connected to the device thus initially reaches the outer annular space at the lower end, preferably flowing upwards in the position of use of the device, and then flowing in the upper region of the device Outer annulus to flow into the inner annulus and sink there.
  • an intermediate bottom is inserted at the lower end in the inner tube, which has a particular centrally arranged passage opening. Further, in the space between the intermediate bottom and the container bottom, an impeller is used and this space is connected via an opening in the inner tube with the outer annular space.

  • an ascending ramp may be provided which extends from the opening of the inner tube into the outer annulus and preferably between the turns of the heating or cooling means in the outer annulus. Due to the rising ramp, the fluid is directed obliquely upwards and directly between the turns. Due to the ramp, the speed of the tempering fluid receives a vertical component, which is advantageous for a helical flow through the outer annular space.
  • the inner annular space is connected via a preferably oval opening in the wall of the inner tube with a flow line of the fluid guide.
  • the flow line is guided away tangentially in the direction of rotation of the impeller from the inner tube, so that the tempering fluid can flow into the supply line according to its rotation direction of the impeller corresponding rotation direction.

  • the return line of the fluid guide is guided in the interior of the inner tube.
  • the return line can in particular open into a collector for returning tempering fluid, which is preferably arranged in the center of the container.

  • the heat carrier plate preferably has cooling fins, so that the heat is released from the plate well to the environment. Together with the long shaft, a strong temperature reduction up to the seal in the area of the drive can be achieved. As a result, advantageously no high-temperature seal for the seal between the shaft and the sleeve must be used.

Nevertheless, for example, water may be present in the tempering fluid due to introduction and evaporate out in the fluid line, in particular if the fluid is heated above 100 ° C. The water content reaches the expansion vessel, which is at about room temperature, where the water condenses.
