The advantage of this design is that if the stress points on the upper surface of the housing 100 are on both sides, the support strength on both sides is improved and the stability is improved by welding the square tube 101 to the left and right side walls of the housing 100.

[0035] Preferably, the second surface 103 of the housing 100 is provided with a plurality of square tubes 101, and the two ends of the square tubes 101 on the second surface 103 are connected to the square tubes 101 on the first surface 102 of the housing 100.

[0036] The second surface 103 of the housing 100 is the upper surface inside the housing 100. A square tube 101 is installed on the surface of the second surface 103. The two ends of the square tube 101 of the second surface 103 are fixedly connected to the outer surface of the square tube of the first surface 102 to form a frame. While increasing the strength of the second surface 103, it can also form a load-bearing point and disperse stress.

[0037] Example 2

[0038] Reference Figures 1-8 In the second embodiment of this utility model, the protective shell includes a plurality of square tubes 101 arrayed on the second surface 103 of the shell 100. Both ends of the square tubes 101 on the second surface 103 are connected to the first surface 102 of the shell 100. The first surface 102 of the shell 100 also has a plurality of square tubes 101 arrayed on it. One end of each square tube 101 on the first surface 102 is connected to the inner wall of the shell 100, and the other end is connected to the square tube 101 on the second surface 103.

[0039] The second surface 103 is welded with the square tube 101, and the square tube 101 of the first surface 102 is welded at the lower surface of the square tube 101 of the second surface 103 and the lower surface of the shell 100, and the square tube 101 of the first surface 102 plays a supporting role, and the square tube 101 of the second surface 103 strengthens the material of the upper surface of the shell 100, and the load capacity of the upper surface is dispersed to the square tube 101 of the first surface 103, thereby forming a supporting role.

[0040] The shell 100 is provided with a switch groove 104.

[0041] As shown in the drawings, the switch groove 104 is arranged on the front and rear surfaces of the shell 100, and the main function is to facilitate the centralized storage of some large cables, and the cables are connected to the inside from the switch groove 104; if the large cable is not needed, a switch door can also be made to facilitate observation or maintenance of the inside. Figures 1-8

[0042] The square tube 101 is arranged around the switch groove 104.

[0043] In order to ensure the strength of the surface of the switch groove 104, the square tube 101 is welded around the switch groove 104, and the square tubes 101 are fixedly connected with each other, so as to ensure the strength of the panel.

[0044] The shell 100 is provided with a hole.

[0045] According to actual conditions, different other structures can be connected to the outer wall of the shell 100, and the positioning holes, mounting holes and the like required for cable routing or bolt mounting can be provided.

[0046] Embodiment 3

[0047] Referring to Figures 1-8 , the third embodiment of the utility model further optimizes the structure of the heat dissipation shell, and comprises a box body 200 arranged on the outer wall of the shell 100, and the box body 200 is in communication with the inside of the shell 100.

[0048] The box body 200 is fixedly installed on the upper part of the shell 100, and when heat is generated in the inside of the shell 100, hot air will enter the inside of the box body 200 due to the upward movement of the hot air, and then the hot air will contact the inner wall of the box body 200, the box body 200 increases the contact surface of the internal heat and the external heat conduction, and improves the heat dissipation efficiency.

[0049] The outer wall of the box body 200 is arranged with the heat dissipation fins 201, and the heat dissipation fins 201 extend to the inside of the box body 200

[0050] ​The fins 201 are half inside the box 200 and half outside the box 200, and the fins 201 are provided in plurality, which functions to further increase the area of the inside in contact with air, and at the same time, increase the contact area of the outside surface with air. When the hot air moves upward, heat is transferred through the inner wall of the box 200 and the surface of the fins 201, and then the heat is transferred to the outside air through the outer surface of the box 200 and the outside fins 201, so as to take away the heat inside the box 200, thereby achieving cooling.

[0051] In summary, the heat generated by the equipment installed inside the shell 100 moves upward, and then exchanges heat with the outside air through the box 200, thereby achieving cooling. The advantage of this design is that the shell 100 can be sealed to ensure that the internal equipment is not affected by the external environment, and at the same time, the internal air temperature can be ensured not to be too high. At the same time, the advantage of the shell 100 using the square tube 101 to strengthen can better ensure the sealing performance.
