As shown in fig. 1 to 3, the case of the LED display device of the present embodiment includes: a back plate 10 and a shroud 20. The enclosing plate 20 is arranged around the edge of the back plate 10 and is positioned at the front side of the back plate 10, and the enclosing plate 20 comprises a first side plate 21 and a second side plate 22 which are oppositely arranged. In the present embodiment, the rear surface of the rear plate 10 is provided with a plurality of first heat dissipation grooves 13 at intervals between the first side plate 21 and the middle portion of the rear plate 10, and the rear surface of the rear plate 10 is provided with a plurality of second heat dissipation grooves 14 at intervals between the second side plate 22 and the middle portion of the rear plate 10. In the present embodiment, the first distance between two adjacent first heat dissipation grooves 13 of the plurality of first heat dissipation grooves 13 becomes gradually larger from the middle of the rear plate 10 to the first side plate 21. A second interval between adjacent two second heat dissipation grooves 14 of the plurality of second heat dissipation grooves 14 becomes gradually larger from the middle of the rear plate 10 to the second side plate 22.

With the technical solution of the present embodiment, compared to the case in the related art in which the back surface of the back plate 10 is a plane, in the present embodiment, a first distance between two adjacent first heat dissipation grooves 13 in the plurality of first heat dissipation grooves 13 is gradually increased from the middle of the back plate 10 to the first side plate 21; the second distance between two adjacent second heat dissipation grooves 14 in the plurality of second heat dissipation grooves 14 is gradually increased from the middle of the rear plate 10 to the second side plate 22, so that the heat dissipation temperature field of the rear plate 10 is more uniform, and the heat dissipation effect of the box body of the LED display device is effectively improved. Therefore, the technical scheme of the embodiment can solve the problem that the back surface of the rear plate of the box body in the related art is a plane, so that the heat dissipation effect of the box body is poor.

It should be noted that a plurality of first pitches are formed in the plurality of first heat dissipation grooves 13, and for two adjacent first pitches in the plurality of first pitches, the first pitch near the middle of the rear plate 10 is smaller than the pitch far from the middle of the rear plate 10. A plurality of second heat dissipation grooves 14 are formed therein, and for adjacent two of the plurality of second pitches, the second pitch near the middle of the rear plate 10 is smaller than the pitch far from the middle of the rear plate 10. The first pitch is a pitch between center lines of the groove bottoms of two adjacent first heat dissipation grooves 13, and the second pitch is a pitch between center lines of the groove bottoms of two adjacent second heat dissipation grooves 14.

The size of the first distance gradually increases from 2.89mm to 10.53mm from the middle of the rear plate 10 to the first side plate 21. The size of the second space gradually increases from 2.89mm to 10.53mm from the middle of the rear plate 10 to the second side plate 22.

As shown in fig. 2 and 3, a third distance between the side walls of two adjacent first heat dissipation grooves 13 of the plurality of first heat dissipation grooves 13 becomes gradually larger from the middle of the rear plate 10 to the first side plate 21, and a fourth distance between the side walls of two adjacent first heat dissipation grooves 13 of the plurality of second heat dissipation grooves 14 becomes gradually larger from the middle of the rear plate 10 to the second side plate 22.

The size of the third space gradually decreases from 6.71mm to 14.84mm in the direction from the middle of the rear plate 10 to the first side plate 21. The size of the fourth space gradually decreases from 6.71mm to 14.84mm from the middle of the rear plate 10 to the second side plate 22.

As shown in fig. 2 and 3, the groove depth of each first heat dissipation groove 13 gradually decreases from the middle of the rear plate 10 to the first side plate 21, and the groove depth of each second heat dissipation groove 14 gradually decreases from the middle of the rear plate 10 to the second side plate 22. Thus, the first distance and the depth of the corresponding first heat dissipation groove 13 are proportionally changed from the middle of the back plate 10 to the direction of the first side plate 21, and the second distance and the depth of the corresponding second heat dissipation groove 14 are proportionally changed from the middle of the back plate 10 to the direction of the second side plate 22, so that the heat dissipation temperature field of the back plate 10 is more uniform, and the heat dissipation effect is better. Meanwhile, the reflecting surface on the back surface of the back plate 10 is changed in proportion, and finally the gradual change effect of light rays from the middle of the back plate 10 to the two sides of the back plate 10 is achieved, so that the appearance is more attractive.

The groove depth of each of the first heat dissipation grooves 13 is gradually reduced from 3.68mm to 1.83mm from the middle of the rear plate 10 to the first side plate 21. The groove depth of each second heat dissipation groove 14 gradually decreases from 3.68mm to 1.83mm from the middle of the rear plate 10 to the second side plate 22.

As shown in fig. 2 and 3, in order to dissipate heat from the rear plate 10 as quickly as possible, the first heat dissipation grooves 13 have an arc-shaped cross-sectional shape. The cross-sectional shape of the second heat dissipation groove 14 is an arc shape. Of course, in the embodiment not shown in the drawings, the cross-sectional shape of the first heat dissipation groove is rectangular. The cross section of the second heat dissipation groove is rectangular.

In order to dissipate the heat on the rear plate 10 as quickly as possible, the first end of each first heat dissipation groove 13 extends to the surface of the third side plate 23, the second end of each first heat dissipation groove 13 extends to the surface of the fourth side plate 24, the first end of each second heat dissipation groove 14 extends to the surface of the third side plate 23, and the second end of each second heat dissipation groove 14 extends to the surface of the fourth side plate 24. Thus, the shape of the first heat dissipation groove 13 facilitates heat conduction, and the shape of the second heat dissipation groove 14 facilitates heat conduction.

As shown in fig. 1 and 2, in order to make the rear plate 10 have a good heat dissipation effect and a high structural strength, the length of the third side plate 23 is greater than that of the first side plate 21. Thus, the length of each first heat dissipation groove 13 on the rear plate 10 is smaller than the length of the third side plate 23, and the length of each second heat dissipation groove 14 on the rear plate 10 is smaller than the length of the third side plate 23.

As shown in fig. 1 and 2, the plurality of first heat dissipation grooves 13 form a first heat dissipation structure, and the plurality of second heat dissipation grooves 14 form a second heat dissipation structure, the first heat dissipation structure and the second heat dissipation structure being symmetrically disposed with respect to a center line L of the middle portion of the rear plate 10. Therefore, the light rays from the middle of the rear plate 10 to the two sides of the rear plate 10 are more obviously changed from deep to shallow, and the appearance is further improved.

As shown in fig. 1 and 2, in order to facilitate the processing and the molding, the plurality of first heat dissipation grooves 13 are provided in parallel, and the plurality of second heat dissipation grooves 14 are provided in parallel.

As shown in fig. 2 and 3, each first heat dissipation groove 13 is a linear groove for further convenience of processing, ease of molding, and good heat dissipation effect. Each second heat dissipation groove 14 is a straight groove. Of course, in the embodiment not shown in the drawings, each of the first heat dissipation grooves is a bent groove. Each second heat dissipation groove is a bent groove.
