[0034] In an embodiment of the utility model, an inner chamber is formed in the shell 1, and a heat dissipation hole 2 and a mounting hole 3 connected to the inner chamber are arranged outside the shell 1. The mounting hole 3 is located at the back plate of the shell 1 and is used to install a heat dissipation fan 4 to dissipate heat from the inner chamber of the shell 1.

[0035] In the embodiment of the utility model, a plurality of support plates 5 are suspended in the inner chamber (such as Figure 2As shown, the present embodiment takes three support plates 5 as an example, that is, the three support plates 5 from top to bottom are divided into a first layer of support plates, a second layer of support plates and a third layer of support plates), so that a heat dissipation channel can be formed between the shell 1 and the support plates 5, and between two adjacent support plates 5, and the heat dissipation channel is connected with the heat dissipation hole 2 to achieve zoned heat dissipation; in addition, the arrangement of the support plates 5 can improve the space utilization rate of the inner chamber and avoid stacking of various equipment, which is not only convenient for early installation and later maintenance, but also can improve the air flow of each heat dissipation channel and accelerate heat dissipation.

[0036] In the embodiment of the utility model, a movable part 6 is arranged in any heat dissipation channel (the position and number of the movable part 6 are determined according to the actual situation and are not limited here too much), and the movable part 6 has an extended state and a contracted state (hereinafter, the movable part 6 arranged on the third support plate is used as an example for explanation), when the movable part 6 is in the extended state, the upper end of the movable part 6 gradually extends in the direction of the second support plate until it abuts against the second support plate, so as to provide an upward support force to the second support plate, thereby improving the overall structural strength of the structure, and when installing, heavier equipment can be placed on the second support plate, without stacking it at the bottom of the shell 1, and partitioning and classification installation can provide a good heat dissipation environment for the inside of the equipment; on the contrary, when the movable part 6 is in the contracted state, the movable part 6 can separate the heat dissipation channel at that place, and is used to limit and fix the equipment at that place. In this way, the extended state and contracted state of the movable part 6 depend on the size and / or weight of the equipment, and a reasonable layout is made in the shell 1 to avoid the large-volume and heavy equipment being concentratedly stacked at the bottom of the shell 1, resulting in slow heat dissipation in the internal environment of the shell 1. It is understandable that the movable member 6 can be switched to various states according to installation requirements to enhance the versatility of the present structure.

[0037] The utility model improves the overall heat dissipation capacity of the heat dissipation structure through the cooperation of multiple support plates 5 and multiple movable parts 6, and provides a good heat dissipation environment for the equipment after optimizing its structural layout.

[0038] like Figure 3 , Figure 4As shown, in one embodiment, the movable part 6 includes a lower box body 601, an upper box body 602 and a driving part; the lower box body 601 is arranged on the shell 1 and / or the support plate 5; the upper box body 602 is detachably arranged on the lower box body 601; the driving part is arranged between the lower box body 601 and the upper box body 602, and is used to drive the upper box body 602 to approach or move away from the lower box body 601, and switch the movable part 6 between the extended state and the contracted state.

[0039] Further, in one embodiment, the driving part is a fork-shaped lifting frame 603, and the upper and lower ends of the fork-shaped lifting frame 603 are respectively movably connected to the upper box body 602 and the lower box body 601.

[0042] Preferably, one end of the threaded rod 604 protrudes from the lower box body 601 and is provided with a rotating handle 605 , and the surface of the rotating handle 605 is provided with anti-slip grooves to increase the friction on the palm.

[0043] like Figure 2 As shown, in one embodiment, a group of opposite end faces of the support plate 5 are provided with connecting ears 7 for connecting to the housing 1, and the other group of opposite end faces thereof are spaced apart from the housing 1. Specifically, in order to suspend and fix the support plate 5 in the inner chamber, the present embodiment provides connecting ears 7 at opposite ends of the support plate 5, and the connecting ears 7 are provided with threaded holes for screwing in screws. In the present structure, bolt connection is uniformly adopted, the installation tool is single, and the installation and manufacturing operation is simple. On the other hand, the other group of opposite end faces of the support plate 5 are spaced apart from the interior of the housing 1, so that the heat dissipation channel formed is connected with the heat dissipation hole 2.
