[0014] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0015] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0016] See attached document Figure 1 6. This utility model provides an installation assembly for a rail transit air conditioning frequency converter 5, comprising: The carriage assembly 1, located on the top of the carriage, includes: a bottom plate 11, a top plate 12, side plates 13, side plates 14, and a back plate 15. The side plates 13 and side plates 14 are respectively connected to the top sides of the bottom plate 11, the top plate 12 is connected to the top of the side plates 13 and side plates 14, and the back plate 15 connects the bottom plate 11, the top plate 12, the side plates 13, and the side plates 14 to form an installation cavity.

[0017] The insulating component 2 includes an insulating plate 21 and a heat dissipation duct 22 sealed and connected to the insulating plate 21. The insulating plate 21 is connected to the side opposite to the back plate 15 to seal the mounting cavity. An opening is formed on the insulating plate 21 for sealing the end of the heat dissipation duct 22. The insulating plate 21 is fitted with the edge plate by bending sheet metal around its perimeter. The heat dissipation duct 22 is formed by a ring-shaped metal plate and has an air inlet and an air outlet. The air inlet is on the side closer to the vehicle compartment, and the air outlet is on the side closer to the inverter 5. The inverter 5 has an approximately cubic structure. The side wall of the inverter 5 has an array of heat dissipation holes near the bottom. The air outlet on the inner side of the heat dissipation duct 22 corresponds to the heat dissipation holes of the inverter 5, improving the heat dissipation efficiency of the inverter 5. At the same time, the main wiring of the radiator is isolated, which can prevent water from entering the main body and causing damage to the wiring.

[0018] Preferably, the system also includes a mounting bracket 3 and a clearance connector 4. The mounting bracket 3 is used to connect to one bottom side of the inverter 5, and the clearance connector 4 is connected to the other bottom side of the inverter 5 and connects to the heat dissipation duct 22. The mounting bracket 3 is a metal bracket connected to the bottom of the inverter 5. The structure of the mounting bracket 3 can be a triangular frame. Since it is located on both sides of the top of the vehicle body, it serves to elevate and balance the installation angle. The clearance connector 4 is used to connect to the bottom corner of the inverter 5 and also avoids obstruction in the heat dissipation duct 22. This ensures heat dissipation efficiency while preventing the airflow from being too low and affecting the air volume.

[0019] Preferably, the inverter 5 extends at least partially into the heat dissipation duct 22 on the side closest to it. The avoidance connector 4 includes an L-shaped connecting plate 41, a first corner plate 42, and a second corner plate 43. The L-shaped connecting plate 41 has a supporting surface for supporting one side of the bottom of the inverter 5 and a connecting portion. The L-shaped connecting plate 41 is connected to the first corner plate 42 through the connecting portion. The first corner plate 42 is connected to the inner side of the heat dissipation duct 22 through a second connecting portion. The L-shaped connecting plate 41 has an L-shaped edge, which can support the frame of the inverter 5 while avoiding occupying a large area in the heat dissipation duct 22 and affecting the airflow. During installation, the L-shaped connector leaves ample installation space in the upper heat dissipation duct 22 for easy installation.

[0020] Preferably, the first corner plate 42 and the second corner plate 43 each include three mutually perpendicular and intersecting vertical surfaces. The two planes of the first corner plate 42 and the second corner plate 43 are arranged side by side and connected. The L-shaped connector connects the first corner plate 42 through the second corner plate 43 and connects the heat dissipation duct 22 through the first corner plate 42. The first corner plate 42 and the second corner plate 43 are both metal plates. During assembly, the bottom of the first corner plate 42 is sequentially secured to the inner bottom of the heat dissipation duct 22 using rivets or screws. Then, the sidewall of the second corner plate 43 is riveted to the L-shaped connector. Finally, the two corner plates are manually brought close together and fixed with bolts. If necessary, the bottom of the inverter 5 can be connected to the bottom of the L-shaped connector with screws. This indirect connection method facilitates the installation of complex structures within a limited space.

[0021] Preferably, the inner edge of the heat dissipation duct 22 is further connected to a sealing element 6. The sealing element 6 surrounds the inner edge of the heat dissipation duct 22 and is used to seal the connection to the side wall of the inverter 5, so that the airflow in the duct flows to the heat dissipation channel of the inverter 5 for heat dissipation. The sealing element 6 can be made of foam sponge or silicone, and is not limited to one of them. Under the action of the sealing element 6, all the airflow in the heat dissipation duct 22 can be stably delivered to the inverter 5 for heat dissipation, providing stable heat dissipation support.

[0022] Preferably, the isolation plate 21 also has a wire passage hole, and the inner side of the hole wall is filled with a sealing ring 7. The wire passage hole serves as a through-hole for the wiring harness of the frequency converter 5, and in cooperation with the sealing ring 7, it can maintain good sealing within the enclosure.

[0023] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
