[0021] Referring to Figures 1-3 , a novel tube sleeve type energy storage heater proposed by the present utility model includes: a housing 1 and a heating plate 4, wherein:

[0022] The housing 1 has a main channel 2 that linearly extends and penetrates at both ends, and a plurality of sub-channels 3 that are circumferentially distributed on the outer periphery of the main channel 2 and extend in the same direction as the main channel 2. At least one end of each sub-channel 3 is a through end. This structural design of the housing 1 is convenient to mold, and the structure is stable and firm. A plurality of heating plates 4 are provided and are respectively installed in each sub-channel 3. The installation method is: the heating plate 4 is inserted from the through end of the sub-channel 3 to complete the installation. This structural design is not only convenient for installation and replacement, but also beneficial to extending the service life of the heating plate 4.

[0023] In this embodiment, a plurality of rib plates 5 are circumferentially distributed on the peripheral wall inside the main channel 2, so as to divide the main pipeline into several flow regions through the rib plates 5, improve the heating efficiency of the medium flowing through the main channel 2, and at the same time, transfer the heat to the central part of the main channel 2 by using the rib plates 5, thereby increasing the uniformity of the medium heated in the main channel 2.

[0024] Further, wing plates 6 extending to both sides are provided at the end of the rib plate 5 near the central part of the main channel 2 and on the side walls on both sides thereof, and a gap is reserved between the wing plates 6 provided on the side walls and the wing plates 6 provided at the end. The wing plates 6 are used to divide the main channel 2 into more small flow areas, further increasing the contact area between the main channel 2 and the medium, thereby further improving the heating efficiency and further enhancing the heating uniformity.

[0025] Further, auxiliary plates 7 formed on the inner wall are provided inside the main channel 2 and between any two adjacent rib plates 5, and there is a gap between the end of the auxiliary plate 7 and the wing plate 6 provided on the upper side wall of the rib plate 5. The design of the auxiliary plate 7 can make up for the deficiency of the large gap at the bottom of the rib plate 5, thereby further enhancing the heating uniformity between the central part and the periphery of the medium flow.

[0026] In addition, in this embodiment, the cross-sectional shape of the auxiliary channel 3 is flat, and the flat structural design facilitates the insertion of the heating plate 4.

[0027] Further, the housing 1 is a regular polygon tubular structural member, and the auxiliary channels 3 are sequentially distributed on each surface of the housing 1. The polygonal structural design facilitates the formation of the flat auxiliary channels 3.

[0028] Further, grooves 11 are provided on the peripheral wall of the housing 1 between any two adjacent auxiliary channels 3. The design of the grooves 11 can form a channel for air flow between two heating areas, avoiding damage due to excessive heat concentration when the heater works.

[0029] In this embodiment, a heat preservation sleeve 8 is sleeved outside the housing 1. The heat preservation sleeve 8 can not only prevent heat dissipation and enhance the effective utilization rate of heat, but also protect the housing 1.

[0030] Connection discs 9 are respectively provided at both ends of the main channel 2 of the housing 1. A neck tube part 10 connecting the two is provided between the connection disc 9 and the housing 1. A sealing groove for preventing a gasket is provided on the outer periphery of the connection disc 9. Through the connection disc 9, it can be quickly connected to the corresponding pipeline and a sealing structure is provided on the connection surface.

[0031] As can be seen from the above, in the present utility model, the main channel 2 and several auxiliary channels 3 are directly formed inside the housing 1 by an integral molding method, and all the auxiliary channels 3 are circumferentially distributed on the outer periphery of the main channel 2, and the heating plate 4 is directly inserted into each auxiliary channel 3. This structural design greatly facilitates the installation and replacement of the heating plate, and the housing is convenient to form and has a firm and reliable structure.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
