Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
As shown in fig. 1-8, a cabinet top structure of power distribution cabinet, this cabinet top structure install in the top of the major structure of power distribution cabinet, and with the major structure sealing connection of power distribution cabinet. Comprises a framework 1, a heat conducting plate 2 covered on the top surface of the framework 1 and side plates 4 covered on the peripheral side surfaces of the framework 1. The framework 1 comprises a bottom frame and a connecting frame arranged on the bottom frame, wherein the bottom frame 11 and the connecting frame 12 are both formed by welding steel structural members. The bottom frame 11 is welded or bolted with the main body framework of the power distribution cabinet. The heat conducting plate 2 covers the top of the connecting frame 12, and the side plate 4 covers the side of the connecting frame 12. The heat conducting plate 2, the side plate 4 and the framework 1 are mutually matched to form a cavity structure with a closed cavity inside. The bottom of the cavity structure is provided with an opening. The main structure of the power distribution cabinet is communicated with the inside of the cavity structure through the opening.
The heat conducting plate 2 and the radiating fins 4 are made of aluminum alloy materials. The above-mentioned heat-conducting plate 2 comprises a first portion 21 and a second portion 22 connected to one or both sides of the first portion 21. The first portion 21 is formed with a plurality of ventilation holes 211. The top surface of the heat conducting plate 2 is provided with a radiating fin group. The radiating fin group comprises a plurality of radiating fins 4 which are arranged in parallel. The heat-dissipating fins 4 are arranged perpendicularly to the heat-conducting plate 2. The heat dissipating fin 4 has a first end extending to the first portion 21 and a second end extending to the second portion 22. Channels are formed between adjacent heat dissipation fins 4. The channel spans the first portion 21 and the second portion 22. A first radiator fan 5 is installed in the passage on the second portion 22. The first heat dissipation fan 5 is fixedly connected with the heat dissipation fins 4 through a bracket. The first heat dissipation fan 5 has an air outlet end arranged towards the second end direction, so that the airflow generated by the first heat dissipation fan 5 flows from the first portion 21 to the second portion 22. In order to meet the use requirement, the heat radiating fin groups can be distributed and installed on the heat conducting plate 2. Through the above structural design, heat is conducted to the heat conducting plate 2 and the heat radiating fins 4, and a part of air flow generated by the operation of the first heat radiating fan 5 flows in the above channels, so that the heat conducted to the heat conducting plate 2 and the heat radiating fins 4 can be guided and exhausted.
Wherein, the specific shape of the heat conducting plate 2 is: the first portion 21 is arranged horizontally and the second portion 22 is arranged obliquely downward. Since the second portion 22 is obliquely arranged downward, dust attached to the heat conductive plate 2 and the radiating fins 4 can be well blown away by the first radiating fan 5.
To increase the packing density of the radiator fins 4 and to facilitate the installation of the first radiator fan 5, the first radiator fan 5 is arranged across at least one passage. Specifically, notches are processed on N (N is greater than or equal to 2) continuous radiating fins 4, the first radiating fan 5 is installed in the notches, and the width dimension of the first radiating fan 5 is not less than the width dimension formed by the N radiating fins 4.
As shown in fig. 6, a connecting bracket 6 is installed below the heat-conducting plate 2. A plurality of second heat dissipation fans 61 are installed on the connection bracket 6 corresponding to the ventilation holes 211. The second heat dissipation fan 61 has an air outlet end facing the air vent 221. When the second cooling fan 61 works, the air flow inside the power distribution cabinet can be guided from bottom to top and exhausted through the vent holes 211.
Wherein, on the major structure of switch board is installed to the cabinet top structure of this embodiment for being convenient for, framework 1 goes up the distribution and installs a plurality of rings 7. The hanging ring 7 is welded or in threaded connection with the framework 1, and the height of a ring body of the hanging ring 7 is higher than that of the radiating fins 4. Through this rings 7, can lift the cabinet top structure of this embodiment by crane the major structure of switch board.
As shown in fig. 1 and 2, in order to meet the outdoor work or protection requirement of the power distribution cabinet, the cabinet top structure of the embodiment includes a covering plate 8. The cover plate 8 has a large area that covers the entire position of the heat-conducting plate 2. The cover plate 8 is installed above the heat-conducting plate 2, a space is formed between the cover plate 8 and the heat-conducting plate 2, and the heat-radiating fins 4 are installed in the space. The cover plate 8 is connected with the framework 1 through a connecting piece.
When the switch board is in operation, a part of heat that the switch board inside produced conducts to on heat-conducting plate 2 and radiating fin 4 to be guided to the outside of switch board. In addition, the hot air flow inside the distribution cabinet is guided by the second cooling fan 61 and discharged to the outside of the distribution cabinet via the ventilation holes 211. The air flow generated by the first heat dissipation fan 5 during operation guides the hot air flow discharged from the vent hole 221 to flow in a direction away from the vent hole 221, so as to disperse the discharged hot air flow. Meanwhile, the heat conducting plate 2 and the heat radiating fins 4 are cooled by the airflow generated by the first heat radiating fan 5. The combined use of the above mode improves the heat dissipation capacity of the power distribution cabinet, the inside and outside air exchange rate of the power distribution cabinet is high, the heat dissipation effect of the power distribution cabinet is good, and the heat dissipation requirement of the power distribution cabinet is effectively met.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
