DETAILED DESCRIPTION OF THE EMBODIMENTS As seen from FIG. 1, the heated gas flows from the core 1 through a hot gas channel 2 into the loop 3. Between the hot gas channel 2 and the loop 3 an apertured plate 4 is arranged, which diverts the hot gas by 90.degree.. In the lower area of the loop 3 a mixing means 5 is arranged according to the invention comprising a plurality of tubes 6, 7, 8, 9 traversing the apertured plate 4 and having their distributor heads 10, 11, 12, 13 above the apertured plate 4. Over the apertured plate 4, the cold gas coming from the mixing device is intermixed with the hot gas. The mixed gas subsequently flows through a heat absorbing component 14, wherefrom it is suctioned by a blower 15 and conducted back through a cold gas line 16 into the core 1. In this embodiment, the gap between the heat absorbing component 14 and the loop 3 is chosen as the cold gas conduit 16. When the valve 17 is opened, the cold gas flows through the mixing device. The flow of the gas is represented by arrows. FIG. 2 shows a mixing means 5 arranged in a loop 3. The valves 18, 19, 20, 21 of the mixing means 5 are arranged in the partition 22 and connected by means of rods 23, 24, 25, 26 with the regulator 27. The tubes 6, 7, 8, 9 are secured in a gas tight manner in the partition 28 and are passing through the apertured plate 4, whereby the distributor heads 10, 11, 12, 13 are arranged above the apertured plate 4. The mixing of the gases takes place above the apertured plate 4. FIG. 3 shows a mixing means 5 with its tubes arranged under the apertured plate 4 and in the hot gas channel 2. The cold gas flows from a mixing means 5 in a direction opposite to the flow direction of the hot gas. The valve 17 is arranged outside the loop 3, thereby establishing a connection between the cold gas line 16 and the valve 17, through the line 16a. FIG. 4 shows a mixing means 5 with its distributor heads arranged above the apertured plate 4 and placed orthogonally to the direction of flow of the hot gas. The mixing of the cold gas with the hot gas takes place under the apertured plate 4. In FIG. 5, a part of the tube 29 is shown with a distributor head 30. The distributor head 30 has several orifices 31, 32 arranged with their principal axes vertically to the surface 35.
