[0021] As shown in Figures 1-6 FIG. 1 is an embodiment one of the modular power distribution switchgear structure of the present application.

[0023] Among them: by switching the air and liquid cooling heat dissipation structure of the heat exchange assembly 7, and / or respectively controlling the working state of the bottom-mounted flow guide pump 4 and the multiple top-mounted flow guide pumps 5, the inside of each cabinet is separately or simultaneously guided and cooled.

[0024] In specific implementation, the switchgear body in the embodiment is provided as three groups, the structure of each group of switchgear bodies is the same, and each group of switchgear bodies is the combination of the cable cabinet 1, the first assembly cabinet 2 and the second assembly cabinet 3, and the three groups of switchgear bodies are horizontally assembled into one body. The following takes the structure of one group of switchgear bodies as an example to describe how each cabinet is guided and cooled.

[0025] Each cable cabinet 1, first assembly cabinet 2 and second assembly cabinet 3 is provided with a heat exchange assembly 7, and the heat exchange assembly 7 is an air and liquid cooling switchable heat dissipation structure; each cable cabinet 1, first assembly cabinet 2 and second assembly cabinet 3 is provided with a top-mounted flow guide pump 5, and the top-mounted flow guide pump 5 and the heat exchange assembly 7 in each cabinet are connected through a pipeline to the same bottom-mounted flow guide pump 4 arranged on the outside of the bottom of the cable cabinet 1.

[0026] The heat exchange assembly 7 is a heat dissipation structure that can switch between air cooling and liquid cooling, which means that the heat exchange assembly 7 has an independent liquid cooling heat dissipation structure and can be connected to a liquid cooling heat dissipation pipeline composed of the bottom-mounted flow guide pump 4 and the top-mounted flow guide pump 5. The bottom-mounted flow guide pump 4 can receive control instructions to independently perform air cooling heat dissipation for each cabinet, or can be connected to the top-mounted flow guide pump 5 to drive the circulation of the heat exchange liquid inside the heat exchange assembly 7, thereby enhancing the heat exchange effect.

[0027] Preferably, the top of each of the three sets of switch cabinet bodies is provided with a top heat exchange groove 8, and the inner bottom surface of the top heat exchange groove 8 is respectively provided with a heat dissipation air cover 9 and a heat dissipation liquid pipe 10 connected to the heat exchange assembly 7.

[0028] Further, the bottom-mounted flow guide pump 4 is arranged on the outside of the bottom of the cable cabinet 1, which functions to realize bottom air extraction and provide a power source for air cooling heat dissipation. In addition, the bottom-mounted flow guide pump 4 can also drive the top-mounted flow guide pump 5. When air is introduced into the interior of the heat exchange assembly 7 through the top-mounted flow guide pump 5, the hot air absorbs heat from the heat exchange liquid in the upper liquid flow channel of the heat exchange assembly 7, thereby enhancing the heat dissipation effect.

[0029] Through the one-to-one correspondence of the structure of the bottom-mounted flow guide pump 4, the multiple top-mounted flow guide pumps 5, and the multiple heat exchange assemblies 7, a single driving unit of the bottom-mounted flow guide pump 4 can control all the heat dissipation mechanisms at different positions, greatly reducing the cost and heat dissipation amount. The transmission mode of the multiple top-mounted flow guide pumps 5 can be adjusted as needed, greatly improving the applicability of the installation position. At the same time, since the top-mounted flow guide pump 5 is arranged at the internal corner position, the space utilization is further improved.

In implementation, the driving motor 43 controls the rotation of the centrifugal wind blades 53 through the second magnetic control linkage 45, the gear transmission set and the third magnetic control linkage 54, so that the air drawn in through the opening at the lower end of the heat exchange assembly 7 is guided upward into the inside of the heat dissipation air duct 9 and discharged.

[0034] In implementation, the first magnetic control linkage 44, the second magnetic control linkage 45 and the third magnetic control linkage 54 are all composed of an assembly shaft, an adjusting shaft sleeve slidably assembled on the assembly shaft, an adjusting electromagnet and an adjusting spring used to control the adjusting shaft sleeve, a split gear fixed on the adjusting shaft sleeve and a linkage gear axially fixed on the other side of the assembly shaft.

[0035] In addition, the bottom-mounted flow guide pump 4 and the plurality of top-mounted flow guide pumps 5 can realize one-to-many transmission, which is realized by the lateral transmission and angle adjustment structure of the bottom-mounted flow guide pump 4. In implementation, in order to cooperate with the angle adjustment, a lateral overturning groove 55 is formed on the outer side of the second drive cover 51, and a overturning adjusting seat 56 used to install the gear transmission set is movably assembled inside the lateral overturning groove 55.

[0037] The elastic telescopic transmission shaft 11 comprises a lateral transmission shaft axially fixed with the movable adjusting gear 14 and an internal telescopic shaft inserted into the transmission end of the lateral transmission shaft through the extrusion spring, and the internal telescopic shaft is controlled to be telescopic adjusted through the opening on the outer side of the lateral transmission shaft, so as to facilitate separation and adjustment.

[0038] In order to cooperate with the limiting and synchronous transmission, two transmission limiting through holes 15 are formed on the inner side of the lateral overturning groove 55, and a synchronous shaft hole 16 is formed inside the limiting gear 12 corresponding to the position of the transmission limiting through hole 15.
