[0088] Figure 7 shows the heating assembly of the heating system located in the heating space 16 of the heat storage device described above. 20 is shown alone. At its bottom, the heating assembly 20 forms a carrier structure.

Each nicam forms a channel that extends vertically, and each is a square It has an outlet. Furthermore, each mounting element 33 is a precise fitting receiver for the heating device 34. This means that a bottom plate 35 and two side walls 36 are formed to divide the receiving space for the purpose. It has a substantially U-shaped cross-section. On the lower side, the bottom plate 35 of the mounting element 33 is Each has a recess 37 in the region of the horizontal edge, and the recess 37 has a rectangular cross-section, below The upper side of the corresponding side wall 36 of the mounting element 33 engages with the recess 37 when stacked. Therefore, the precise positioning of the upper mounting element 33 is ensured. The rib engages with the recess 37 in the lower layer of the heating unit 28.

[0090] In the modified example shown in Figure 9, the side wall 36 and bottom plate 35 of the mounting element 33 are made integrally. In the modified example shown in Figure 8, the side walls 36 are each inserted into the bottom plate. They are separate components. Furthermore, adjacent mounting elements each share a side wall. Therefore, this side wall spans the adjacent bottom plate 35.

[0092] The heating device 34 of the heating unit 28 is substantially structurally the same, and the inlet base surface is Each has, in this case the inflow base surface is the side wall 36 of the two consecutive mounting elements 33 It corresponds to the surface in between. When installed, the heating device 34 is connected to these two mounting elements 33 It is placed on the bottom plate 35. In particular, as shown in Figures 9-11, the heating device 34 is placed on the bottom plate 35. Each of these consists of six heating plate units connected in series: 39A, 39B, 39C, 39D. Includes 39E and 39F. For this purpose, heating plate units 39A and 39B, Heating plate units 39B and 39C, heating plate units 39C and 39D, heating plate The heating units 39D and 39E, and the heating plate units 39E and 39F are, in each case They are connected to each other via contact sheets 40 located on the corresponding front surfaces of the heating device 34. In each case, an electrical insulating material is placed between adjacent heating plate units, for example A partition 41 made of ceramic material is arranged, and each adjacent contact To ensure electrical insulation between the plates 40. Furthermore, the heating device 34 has two corresponding Includes a side wall 42 that touches or abuts against the corresponding side wall 36 of the mounting element 33. To establish proper contact, the heating device 34 has a first connector 43 and a second connector 44. Connectors 43 and 44 are located on the corresponding front surfaces of the heating device 34, respectively. It is made of a contact plate 40 and plate parts that are aligned in a straight line. The connector 43 is The connector 44 is electrically connected to the front of the heating plate 39A, and the heating plate unit It is electrically connected to the front of the 39F.

[0093] Each individual heating plate unit 39A, 39B, 39C, 39D, 39E, 39F is Each includes multiple heating plate strips 45, 46.

[0094] In the embodiment shown in Figure 11, a corrugated heating plate strip 45 and a flat heating plate The strips 46 are arranged alternately and continuously in the stacking direction, and the wave heating The plate strip 45 is placed on the adjacent flat heating plate strip 46, and those waves It is supported by the top of the shape. The outer corrugated heating plate strip 45 corresponds It is also supported by the partition 41 or the corresponding side wall 42.

[0095] In those end regions, the heating plate strips 45, 46 are parallel to each other, They are connected to each other via the pacer structure 47, and the corresponding connectors 43 and 44 The contact between the heat plate stack and / or the corresponding contact plate 40 is also established. The structure 47 is positioned between the parallel end regions of adjacent heating plate strips and is mutual Lining plate 48, which is realized as a space element, is welded or soldered to the surface. Includes. Each lining plate 48 is a wave of a corrugated heating plate strip 45. It has a thickness that corresponds to the amplitude of its shape.

[0096] The waveform of the heating plate strip 45 is large for the gas flow that flows through the heating device 34. A honeycomb structure is formed that provides a large inflow surface.

[0097] In an alternative embodiment, some lining plates are adjacent to each other in a heating plate st The spacer structure may be placed between the lips. It is also conceivable that this could be implemented as a comb structure into which the elements are inserted.

[0098] Furthermore, in the modified examples shown in Figures 9-12, a corrugated heating plate is used on the heating plate stack. Only heating strips are provided, and these corrugated heating plate strips are light Through a conductive spacer structure consisting of a cutting plate, etc., their two end regions interact with each other. The description refers to the configuration in which each of them is connected to the others.

[0099] The heating device of the heating unit has different structures in different layers 27 of the heating assembly 20. It is generally conceivable that the honeycomb channel shape may have different heights and / or shapes. In this embodiment, the heating device 34 for layer 27 of the heating assembly 20 is via a contact plate 49. They are then connected in series. It is certainly conceivable that the heating devices 34 could also be switched to a parallel configuration. Furthermore, in the present embodiment, the consecutive layers are connected in pairs in parallel via the contact strip 50. The heating device 34 is connected. Generally, the heating device 34 can be wired in any way as needed.

[0100] The temperature of the gas flow heated by the heating assembly 20 can be determined. To achieve this, the heat element 51 is positioned in the cover 29 in the transverse bore of the molded brick 30. .

[0101] Figures 13-17 show a heat storage device 60 that largely corresponds to the heat storage devices in Figures 1-3. However, the heating space 16 that forms the heating channel is equipped with the above-described type of stacked heater. They differ in that they do not. In fact, the resistive heating element 61 is engaged with the heating space 16. The heating element 61 is made from a heating coil and the like, and power grids are connected via the connection region 62. It is connected to the dot.
