Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and more specifically, to a heat-conducting bus duct. Background Art

[0002] Bus ducts are widely used in power transmission and supply of industrial plants and high-rise buildings. Due to the high current and high heat generated by the bus duct itself, coupled with the high working environment temperature, especially in manufacturing enterprises such as steel mills, the working temperature is above 180 degrees. In addition, the bus duct works for a long time, and heat accumulation will cause damage to the bus duct. Therefore, the heat resistance of the bus duct is particularly important. However, the heat resistance of the bus ducts currently on the market is relatively low and it is difficult to meet the demand.

[0003] For example, the heat-conducting bus duct disclosed in application publication number CN 103594990 A includes a shell and a multi-phase conductive bar installed in the shell. At least one phase of the conductive bar is composed of two parallel half-pieces, and a heat-conducting plate is clamped and fixed between the two half-pieces. The two side edges of the heat-conducting plate are close to the wall panel of the shell. By arranging a two-piece conductive bar, a larger surface area can be obtained under the same cross-sectional area.

[0004] In the above, since the shell and the heat conducting plate have no specific heat conducting structure and no corresponding discharge path, the hot air generated by the conductive row is difficult to discharge, resulting in poor heat dissipation capacity of the shell and the heat conducting plate. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a heat-conducting bus duct with strong heat dissipation capability.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A heat-conducting bus duct comprises a shell and a plurality of conductive bars arranged in the shell, a heat-conducting plate is arranged between adjacent conductive bars, a transmission channel is arranged on the heat-conducting plate, one end of the transmission channel is connected to the conductive bar, and the other end is communicated with the shell, a gas dispersion port is arranged on the shell, a plurality of accommodating shells are arranged in the shell, the accommodating shell has a cavity, a column is arranged in the cavity, an external thread is arranged on the outer wall of the column, a convex end face of the external thread abuts against the inner wall of the cavity, a rotating channel for hot gas to circulate is formed between the concave end face of the external thread and the shell, one end of the rotating channel is communicated with the transmission channel, and the other end thereof is communicated with the gas dispersion port.

[0008] The utility model is further configured as follows: the transmission channel includes an air inlet, a first connecting groove, a second connecting groove, an air outlet 1 and an air outlet 2, the air inlet is connected to the conductive bar, the air outlet 1 and the air outlet 2 are both connected to the rotating channel, the first connecting groove is respectively connected to the air inlet and the air outlet 1, and the second connecting groove is respectively connected to the air inlet and the air outlet 2.

[0009] The utility model is further configured as follows: a plurality of storage grooves are opened on the shell, the accommodating shell is placed in the storage grooves, and the outer wall of the accommodating shell is connected to the inner wall of the storage grooves.

[0010] The utility model is further configured as follows: the column is made of aluminum.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The hot air generated by the conductive row enters from the air inlet on the heat conducting plate, and a part of the hot air is transmitted from the air outlet one to the air outlet one through the first connecting groove, and the other part of the hot air is transmitted from the air outlet to the air outlet two through the second connecting groove. The hot air can be dispersed through the two parts, and the hot air placed at the air outlet one enters the rotating channel and spirally rotates with the hot air to achieve the heat dissipation effect, and finally the hot air flows out from the air dispersion port. Similarly, the hot air placed at the air outlet two enters the rotating channel for rotational heat dissipation, and finally flows out from the air dispersion port. Since heat conducting plates are installed between adjacent conductive rows, and two accommodating shells are installed in the shell and are placed on both sides of the heat conducting plates, the generated hot air is dissipated through the heat dissipation route, thereby having a strong heat dissipation capacity.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0018] like Figure 1 to Figure 2 As shown, the heat-conducting bus duct includes a shell 1 and a plurality of conductive bars 2 placed in the shell 1, a heat-conducting plate 3 is installed between adjacent conductive bars 2, a transmission channel is opened on the heat-conducting plate 3, one end of the transmission channel is connected to the conductive bar 2, and the other end is connected to the shell 1.

[0019] The transmission channel includes an air inlet 9, a first connecting groove 10, a second connecting groove 11, an air outlet 12 and an air outlet 2 13. The air inlet 9 is connected to the conductive bar 2, and the air outlet 12 and the air outlet 2 13 are both connected to the shell 1. The first connecting groove 10 is respectively connected to the air inlet 9 and the air outlet 1 12, and the second connecting groove 11 is respectively connected to the air inlet 9 and the air outlet 2 13.

[0020] The shell 1 is provided with an air diffusion port 4 and a plurality of storage grooves, in which a receiving shell 5 is installed. The receiving shell 5 is placed in the storage groove so that the outer wall of the receiving shell 5 and the inner wall of the storage groove are fixed.

[0021] The accommodating shell 5 has a cavity, in which a column 6 is installed. The column 6 is made of aluminum because aluminum can dissipate heat better. An external thread 7 is installed on the outer wall of the column 6. The convex end face of the external thread 7 is in conflict with the inner wall of the cavity. A rotating channel 8 for hot air to circulate is formed between the concave end face of the external thread 7 and the outer shell. One end of the rotating channel 8 is respectively connected to the air outlet 12 and the air outlet 2 13, and the other end is connected to the air dispersion port 4.

[0022] Working principle: The hot air generated by the conductive bar 2 enters from the air inlet 9 on the heat conducting plate 3, a part of the hot air is transmitted from the air outlet 1 to the air outlet 1 through the first connecting groove 10, and the other part of the hot air is transmitted from the air outlet to the air outlet 2 13 through the second connecting groove 11. The hot air can be dispersed through the two parts.

[0023] The hot air at the first air outlet 12 enters the rotating channel 8 and spirally rotates with the hot air to achieve a heat dissipation effect, and finally the hot air flows out from the air dispersion port 4. Similarly, the hot air at the second air outlet 13 enters the rotating channel 8 for rotational heat dissipation, and finally flows out from the air dispersion port 4. Since heat conducting plates 3 are installed between adjacent conductive bars 2, and two accommodating shells 5 are installed in the shell 1 and are located on both sides of the heat conducting plates 3, the generated hot air is dissipated through the heat dissipation route, thereby having a strong heat dissipation capacity.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
