[0013] Furthermore, longitudinally arranged radiating ridges are arranged at intervals along the width direction on the upper side surface of the upper cover.

[0014] Furthermore, a hanging slot is provided on the back side of the lower cover shell along the length direction.

[0027] In this embodiment, the inner sides of the two side plates of the lower cover are longitudinally provided with connecting pieces 4 along the length direction, and the two side plates of the lower cover and the upper cover are slidably connected with the corresponding connecting pieces. Specifically, the two side plates of the lower cover and the upper cover are longitudinally provided with longitudinal guide rails 13 and 21 along the length direction, and the upper and lower parts of the connecting pieces are longitudinal guide grooves 41, which cooperate with the longitudinal guide rails corresponding to the lower cover and the upper cover, so as to realize the connection between the upper cover and the lower cover, and help to provide a deformation gap for the thermal deformation and expansion of the upper cover and the lower cover.

[0028] In this embodiment, the longitudinal guide rail is in a horizontal fold shape (inverted L shape) and is arranged on the inner side of the free end of the side panel of the corresponding lower cover shell and upper cover, and the longitudinal guide rail is integrally formed with the corresponding side panel of the lower cover shell and upper cover; the longitudinal guide groove is in a vertical fold shape (inverted L shape), and a horizontal partition 42 is arranged between the two longitudinal guide grooves.

[0029] In this embodiment, the inner side of the connector is provided with longitudinal slots 43 along the length direction, and a heat insulation board 5 arranged along the length direction is installed between the two longitudinal slots, and the heat insulation board is a galvanized board. A chamber is formed between the heat insulation board and the upper cover, which helps to reduce the heat flow into the lower cover, reduce heat loss, and help to radiate heat outward through the upper surface of the upper cover.

[0030] In this embodiment, a sealing plate 22 is fixedly installed at the other end of the upper cover by screws to form a thermal deformation expansion and contraction interval with the other end plate, and a shielding plate 14 is transversely installed in the lower cover and located at the lower side of the sealing plate, one end of the shielding plate is in contact with the other end plate, and the longitudinal length of the shielding plate is greater than the thermal deformation expansion and contraction interval. Thus, the lower cover and the upper cover are both closed, reducing the heat loss from the lower cover to the outside and improving the aesthetic effect.

[0031] In this embodiment, the two ends of the heat insulation plate can be respectively abutted against the sealing plate and an end plate, which helps to reduce the heat entering the lower cover shell.

[0032] In this embodiment, longitudinal slots 15 are provided on the inner walls of the two side plates of the lower housing along the length direction, and both ends of the shield plate extend into the longitudinal slots, and a limit baffle 16 is installed in the lower housing to abut against the other end of the shield plate.

[0033] In this embodiment, a longitudinal installation groove 23 composed of a pair of arc-shaped plates is arranged in the upper cover along the length direction, the number of the longitudinal installation grooves can be two or more, and the arc-shaped plates are integrally formed with the upper cover. The heating pipe is embedded in the longitudinal installation groove.

[0034] In this embodiment, in order to better radiate heat, the upper side surface of the upper cover is provided with longitudinally arranged radiation ridges 26 at intervals along the width direction; the back side of the lower cover is provided with hanging slots 17 along the length direction, so as to facilitate the hanging installation of the heater.

Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0037] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0038] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.
