Abstract
Description
Technical Field
[0001] This utility model relates to the field of busbar cooling technology, specifically a fire-resistant busbar with strong heat dissipation. Background Technology
[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute a large amount of power to various components of a distributed system. In traditional technology, in order to reduce the heat generated by the busbar trunking during operation and to prevent damage caused by excessive temperature, heat dissipation fins are installed on the outer shell of the busbar trunking to dissipate the heat generated by the busbars.
[0003] However, dust easily accumulates at the heat dissipation fins. If dust is not cleaned effectively or not at all, the heat dissipation efficiency of the fins can be reduced, increasing the risk of damage to the busbar trunking. Existing busbar trunking systems are not conducive to cleaning dust from the copper busbars, thus affecting the heat dissipation performance. To address this, we propose a fire-resistant busbar trunking with strong heat dissipation properties. Utility Model Content
[0004] The purpose of this invention is to provide a fire-resistant busbar trunking with strong heat dissipation to solve the problem of poor heat dissipation of existing busbar trunking mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire-resistant busbar trunking with strong heat dissipation, comprising a horizontal cover plate and a vertical side plate, wherein the vertical side plate and the horizontal cover plate are connected by screws, and a copper busbar is arranged inside the space formed by adjacent horizontal cover plates and adjacent vertical side plates. A fixing strip is fixedly installed on the horizontal cover plate, and the copper busbar is snapped onto the fixing strip. Heat dissipation fin groups two are arranged at intervals on both sides of the fixing strip, and heat dissipation fin groups one are arranged at intervals on the outer side of adjacent heat dissipation fin groups two. Heat dissipation plates are fixedly installed on the outer side of heat dissipation fin groups one and two, and heat dissipation fin groups one and two are fixed to the corresponding heat dissipation plates. The heat dissipation plates are embedded in the horizontal cover plate, and the heat dissipation plates and the horizontal cover plate are connected by screws.
[0006] Both the first heat dissipation fin group and the second heat dissipation fin group consist of multiple heat dissipation fins of different lengths, and the multiple heat dissipation fins are arranged in an equidistant manner from the outside to the inside.
[0007] Preferably, the first heat dissipation fin group and the second heat dissipation fin group are arranged back to back, and the first heat dissipation fin group and the second heat dissipation fin group are parallel to each other.
[0008] Preferably, ventilation mesh two and ventilation mesh one are provided on the outer side of the vertical side plate.
[0009] Preferably, the second ventilation mesh and the first ventilation mesh are located on the outer side of the corresponding second heat dissipation fin group and the first heat dissipation fin group.
[0010] Preferably, the heat sinks of the first heat sink assembly and the heat sinks of the second heat sink assembly are respectively disposed on the front and rear sides of the corresponding copper busbar.
[0011] Preferably, the horizontal cover plate has a "T"-shaped groove for inserting the heat sink, and the lower end of the "T"-shaped groove is flush with the inner side of the horizontal cover plate.
[0012] Preferably, the heat sinks of both heat sink fin group one and heat sink fin group two are attached to the copper busbar.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This type of fire-resistant busbar trunking with strong heat dissipation features heat dissipation fin group one and heat dissipation fin group two arranged inside the space formed by adjacent horizontal cover plates and adjacent vertical side plates. Each heat dissipation fin group one and heat dissipation fin group two consists of multiple heat dissipation fins of different lengths, which are arranged at equal intervals from the outside to the inside. This arrangement guides the incoming airflow, facilitating airflow between adjacent copper busbars and carrying away the heat from the copper busbars. At the same time, heat dissipation fin group one and heat dissipation fin group two are fixed to corresponding heat dissipation plates, which are in direct contact with the air. During use, some of the heat generated by heat dissipation fin group one and heat dissipation fin group two can be transferred to the heat dissipation plates, thereby further improving the heat dissipation efficiency of heat dissipation fin group one and heat dissipation fin group two.
[0015] 2. This type of fire-resistant busbar trunking with strong heat dissipation features heat dissipation fin group one and heat dissipation fin group two fixed to the corresponding heat dissipation plate. By removing the corresponding heat dissipation plate, heat dissipation fin group one or heat dissipation fin group two can be taken out to clean the dust on heat dissipation fin group one and heat dissipation fin group two, further ensuring the heat dissipation effect of heat dissipation fin group one and heat dissipation fin group two.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Please refer to Figure 1-6 This utility model provides a technical solution: a fire-resistant busbar trunking with strong heat dissipation, comprising a horizontal cover plate 1 and a vertical side plate 2, the vertical side plate 2 and the horizontal cover plate 1 being connected by screws, wherein both the horizontal cover plate 1 and the vertical side plate 2 have a "U" shaped cross-section, and the vertical side plate 2 is disposed between adjacent horizontal cover plates 1. A copper busbar 4 is disposed inside the space formed by adjacent horizontal cover plates 1 and adjacent vertical side plates 2, and a fixing strip 9 is fixedly installed on the horizontal cover plate 1, the copper busbar 4 being snapped onto the fixing strip 9, the fixing strip 9 serving to assist in fixing the copper busbar 4.
[0025] Please see Figure 3 The busbar trunking has two sets of heat dissipation fins 8 spaced apart on both sides of the fixing strip 9. A set of heat dissipation fins 6 is spaced apart on the outer side of each set of two heat dissipation fins 8. A heat dissipation plate 3 is fixedly installed on the outer side of the sets of two heat dissipation fins 8 and 6. The heat dissipation plate 3 is embedded in the horizontal cover plate 1, and the heat dissipation plate 3 and the horizontal cover plate 1 are connected by screws. The sets of two heat dissipation fins 6 and 8 are fixed to the corresponding heat dissipation plates 3. Ventilation mesh 5 and ventilation mesh 7 are provided on the outer side of the vertical side plate 2. The ventilation mesh 5 and ventilation mesh 7 ensure ventilation of the busbar trunking while further reducing the amount of dust entering the busbar trunking. The ventilation mesh 5 and ventilation mesh 7 are located on the outer side of the corresponding sets of two heat dissipation fins 8 and 6. The heat sink 3 is installed on the adjacent horizontal cover plate 1, and it can contact the air. After the heat from the heat sink fin group 1 6 and the heat sink fin group 2 8 is transferred to the heat sink 3, the heat sink 3 can contact the air, which can quickly reduce the temperature of the heat sink fins, thereby further improving the heat dissipation effect of the bus trunking.
[0026] It is worth noting that the heat sink 3 is fixedly installed on the horizontal cover plate 1 with screws. After a certain period of use, dust easily accumulates on the heat sink fin group 1 6 and heat sink fin group 2 8 inside the busbar trunking. At this time, by removing the corresponding heat sink 3, the corresponding heat sink fin group 1 6 or heat sink fin group 2 8 can be taken out and the dust on the heat sink fin group 1 6 and heat sink fin group 2 8 can be cleaned, further ensuring the heat dissipation effect of the heat sink fin group 1 6 and heat sink fin group 2 8.
[0027] Please see Figure 4-6 In this embodiment, both heat dissipation fin group one 6 and heat dissipation fin group two 8 are composed of multiple heat dissipation fins of varying lengths, and these fins are arranged in an equidistant manner from the outside in. Heat dissipation fin group one 6 and heat dissipation fin group two 8 are arranged back-to-back and are parallel to each other. Since heat dissipation fin group one 6 and heat dissipation fin group two 8 are spaced apart, after airflow from the outside, it enters the busbar groove through ventilation mesh two 5 and ventilation mesh one 7, carrying away heat from heat dissipation fin group one 6 and heat dissipation fin group two 8, thereby achieving the effect of heat dissipation for heat dissipation fin group one 6 and heat dissipation fin group two 8.
[0028] Furthermore, the heat sinks of heat sink fin group 1 6 and heat sink fin group 2 8 are respectively disposed on the front and rear sides of the corresponding copper busbar 4, and both heat sinks of heat sink fin group 1 6 and heat sink fin group 2 8 are in contact with the copper busbar 4. By setting heat sinks on both sides of the copper busbar 4, the heat generated during the use of the copper busbar 4 can be transferred to the heat sinks, thereby reducing the temperature of the copper busbar 4 and further ensuring the stability of the busbar trunking during use.
[0029] It is worth noting that in this embodiment, the horizontal cover plate 1 is provided with a "T"-shaped groove for inserting the heat sink 3, and the lower end of the "T"-shaped groove is flush with the inner side of the horizontal cover plate 1.
[0030] Working Principle: In this type of fire-resistant busbar trunking with strong heat dissipation, the copper busbars 4 generate heat during use, which can affect the performance of the busbar trunking. At this time, the ventilation mesh 2 5 and ventilation mesh 1 7 allow airflow from the outside into the busbar trunking. The heat dissipation fins, which grow upwards at equal intervals from the outside to the inside, guide the incoming airflow, allowing it to enter between adjacent copper busbars 4 and accelerating the heat dissipation of the copper busbars 4. Furthermore, by fixing the heat dissipation fin group 1 6 and heat dissipation fin group 2 8 to the heat dissipation plate 3, and by setting the heat dissipation plate 3 on the adjacent horizontal cover plate 1, it can contact the air. After the heat from the heat dissipation fin group 1 6 and heat dissipation fin group 2 8 is transferred to the heat dissipation plate 3, the contact between the heat dissipation plate 3 and the air can quickly reduce the temperature of the heat dissipation fins, thereby effectively ensuring the performance of the busbar trunking.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
