[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The embodiment of the present invention provides a simple heat storage body, and a plurality of simple heat storage bodies can be spliced ​​to form a heat storage overall structure. Figure 1 The present invention provides a simple heat storage body.

[0030] Specifically, Figure 1 As shown, in this embodiment, the simple heat storage body 1 includes two end faces 11 and four side faces 12 (the four side faces 12 of the simple heat storage body 1 enclose the peripheral side faces of the simple heat storage body 1); the two end faces 11 are spaced apart and opposite to each other in the first direction; the four side faces 12 are connected between the two end faces 11 and are connected in sequence; each side face 12 is formed with a groove 13 passing through the two end faces 11 and a convex portion 14 adjacent to the groove 13, and the shape of the convex portion 14 is adapted to the shape of the groove 13, and is used for splicing multiple simple heat storage bodies 1 with each other through the convex portion 14 and the groove. The groove 13 may be formed on the side surface 12 by protruding a plurality of protrusions arranged in parallel and spaced apart on the side surface 12, where the protrusions are convex portions 14, and a groove 13 is formed between two adjacent protrusions; or the groove 13 may be directly formed on the side surface 12, for example, when N (N is an integer greater than or equal to 1) grooves 13 are formed on any one side surface 12, N+1 convex portions 14 may be formed on the any one side surface 12, for example, Figure 1 As shown, in this embodiment, a groove 13 is formed on each side surface 12 to form two protrusions 14 on each side surface 12 .

[0031] The same concave-convex structure is formed on each side surface 12 of the simple heat storage body 1 provided in the embodiment of the present invention, and a plurality of simple heat storage bodies 1 are spliced ​​together through the concave-convex structure. The structure of such a simple heat storage body 1 is relatively simple, the processing difficulty and cost are relatively low, and the simple heat storage body 1 can be ensured to have sufficient structural strength; and Figure 2As shown, when the simple heat storage bodies 1 are spliced ​​to form the heat storage overall structure 100, any two side surfaces 12 of the two simple heat storage bodies 1 can be spliced ​​along the extension direction or the groove depth direction of the groove 13, and the splicing direction is not restricted, which is more convenient to use.

[0032] The material of the simple heat storage body 1 is preferably a high temperature refractory material such as a magnesia brick, and the simple heat storage body 1 is a rectangular or cube-shaped arrangement. The simple heat storage body 1 is a symmetrical structure that is not only easy to process but also has good strength. For example, Figure 1 As shown, in this embodiment, the simple heat storage body 1 is a cubic structure with grooves 13 provided on four side surfaces 12. At the same time, in this embodiment, the grooves 13 on two side surfaces 12 that are spaced apart and opposite to each other in a direction perpendicular to the first direction among the four side surfaces 12 are opposite to each other in the spacing direction of the two side surfaces 12, so that the multiple grooves 13 on the simple heat storage body 1 also have a symmetrical relationship.

[0033] The shape of the convex portion 14 matches that of the concave portion 13. The concave portion 13 may be a linear groove extending along a straight line or a non-linear groove, and the convex portion 14 may also be a linear or non-linear groove. For example, in this embodiment, the concave portion 13 and the convex portion 14 are extended along the first direction, which can reduce the difficulty of the processing of the concave portion 13 and the convex portion 14. In addition, in this embodiment, the concave portion 13 is a square groove.

[0034] Usually, the convex portion 14 and the concave portion 13 are arranged with equal width, and the width of the convex portion 14 is the dimension of the convex portion 14 in the groove width direction of the concave portion 13. The concave portion 13 divides any side surface 12 equally in the groove width direction. For example, when one concave portion 13 and two convex portions 14 are formed on one side surface 12, the concave portion 13 divides the side surface 12 into three equal parts, and the widths of the concave portion 13 and the convex portion 14 are both 1 / 3 of the dimension of the side surface 12 in the groove width direction; for another example, when n (n is an integer greater than 1) parallel concave portions 13 and n+1 convex portions 14 are formed on each side surface 12, the concave portion 13 divides the side surface 12 into 2n+1 equal parts, and the widths of the concave portion 13 and the convex portion 14 are both 1 / (2n+1) of the dimension of the side surface 12 in the groove width direction.

[0035] As described above, one or more grooves 13 may be formed on one side surface 12 . Usually, the same number of grooves 13 are formed on four side surfaces 12 .

[0036] like Figure 1As shown, in this embodiment, the simple heat storage body 1 is provided with a through hole 15 that passes through the two end faces 11. The provision of the through hole 15 increases the internal heat exchange area of ​​the simple heat storage body 1, and can also play a role in reducing the resistance of the simple heat storage body 1 to the gas flow. Among them, the through hole 15 is provided in the shape of a circular hole, a square hole or a diamond hole. The through hole 15 can be a linear hole extending along a straight line or a non-linear hole. For example, in this embodiment, the through hole 15 is a circular hole extending along the first direction, which can reduce the difficulty of the processing technology of the through hole 15.

[0037] The through holes 15 are usually arranged in a plurality at intervals. The plurality of through holes 15 may be arranged along the boundaries of a circle, a square, a triangle or the like. Figure 1 As shown, in this embodiment, nine through holes 15 are provided, and the nine through holes 15 are arranged in three rows and three columns with equal spacing. This can not only increase the internal heat exchange area of ​​the simple heat storage body 1, but also enhance the heat exchange uniformity of the simple heat storage body 1.

[0038] The embodiment of the present invention also provides a heat storage integral structure, such as Figure 2 As shown, the heat storage overall structure 100 includes a preset number of simple heat storage bodies 1 as described above, and the preset number of simple heat storage bodies 1 are staggered and spliced ​​through grooves 13 and convex parts 14, so as to enclose and form an air guide channel 2 between the adjacent multiple simple heat storage bodies 1. Two simple heat storage bodies 1 can be staggered and snapped in any direction of front and back, left and right, or up and down through the grooves 13 and the convex parts 14, so that an air guide channel 2 will be enclosed and formed between the adjacent multiple simple heat storage bodies 1. For example, when the simple heat storage body 1 is a cubic structure, an air guide channel 2 with a square cross-section and extending along the first direction will be enclosed and formed between the four adjacent simple heat storage bodies 1. The air guide channel 2 is used for air to exchange heat outside the simple heat storage body 1, and the air can also exchange heat in the through hole 15 of the simple heat storage body 1. The combination of the two internal and external heat exchange channels improves the heat exchange efficiency and makes the temperature distribution of the simple heat storage body 1 more uniform.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
