Technical Field

[0001] This utility model relates to the field of auxiliary heat dissipation devices for busbar trunking, and particularly to an auxiliary heat dissipation device for busbar trunking. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Existing busbar trunking has mounting brackets for fixing conductive copper busbars inside. Because the brackets are firmly attached to the conductive copper busbars, the heat generated by the conductive copper busbars during operation is not easily dissipated and tends to accumulate.

[0004] Therefore, it is necessary to propose an auxiliary heat dissipation device for busbar trunking to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary heat dissipation device for busbar trunking, in order to solve the problem that existing busbar trunking has a bracket for installing and fixing conductive copper busbars. Because the bracket is firmly attached to the conductive copper busbars, the heat generated by the conductive copper busbars is not easily dissipated in the attachment area, and the heat is prone to accumulate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary heat dissipation device for a busbar trunking, comprising a trunking body and a shielding cover installed on the top of the trunking body. Grooves are provided on both sides of the interior of the trunking body, and a plug-in groove is provided between the two grooves. The plug-in groove is located at the bottom of the interior of the trunking body and penetrates through the bottom of the trunking body. A heat dissipation mechanism is plugged into the plug-in groove.

[0007] The heat dissipation mechanism includes a U-shaped card with its U-shaped opening facing downwards. Multiple bases are located at the bottom of the U-shaped card and are connected side-by-side along the length of the U-shaped card. Top seats are telescopically mounted on the tops of the multiple bases. Conductor grooves are provided on opposite sides of the bases and top seats, and heat dissipation holes are provided in the conductor grooves. Insert blocks are connected to the bottoms of the multiple bases, and through slots are provided at the bottoms of the insert blocks. The interiors of the top seats, bases, and through slots are sequentially connected.

[0008] Preferably, the top seat and the base are respectively provided with a first cavity and a second cavity, the bottom of the base is fixed with a square tube, the top of the base is provided with a slot for inserting the square tube, the first cavity and the heat dissipation hole are connected, and the first cavity, the inside of the square tube, the second cavity and the inside of the through slot are connected in sequence.

[0009] Preferably, the insert block is inserted into the inside of the insertion slot, and a spring telescopic rod is fixed between the top of the top seat and the top of the inside of the U-shaped card. Multiple top seats are provided, and the multiple top seats are connected side by side. The top seats are lifted and lowered inside the U-shaped card.

[0010] Preferably, the two ends of the U-shaped card are respectively engaged inside the corresponding grooves.

[0011] Preferably, both ends of the groove and the shielding cover on opposite sides are provided with through holes, and a fixing bolt is provided between the two corresponding through holes.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In the actual operation of this utility model, the conductive copper busbar can be installed between the corresponding top seat and base. The top seat and base can clamp and fix the individual conductive copper busbar and isolate it. At the same time, the heat generated by the conductive copper busbar can enter the heat dissipation hole and finally be discharged from the through groove to the outside of the groove, reducing the accumulation of heat and improving the heat dissipation efficiency.

[0014] 2. Furthermore, the top mount can slide up and down on the top of the base via a square tube, thereby changing the distance between the top mount and the base to accommodate conductive copper busbars of different heights. At the same time, since a spring telescopic rod is provided between the top mount and the U-shaped clip, the top mount can always be in contact with the top of the conductive copper busbar to complete the fixation.

[0015] 3. In addition, adding a U-shaped clip can increase the structural strength between the two sides inside the slot, protect the heat dissipation mechanism, and improve the installation stability of the heat dissipation mechanism through its cooperation with the groove.
