Abstract

The utility model discloses a heat radiation type bus ducts. The forming of steel bending or the simple aluminium profiles is generally adopted for the shell of the prior bus ducts. The bus ducts of the shell made by these two forms have poor heat-sinking capacity. In order not to exceed the standard of the temperature increasing of products, the cross-section area of a conductor has to be increased. In the circumstances of large current, two copper bars are required to use for each phase. The product size is too large, thereby the users need provide additional space to install and the installation is extremely inconvenient. In the utility model, because the shell is provided with the heat sink strips protruding outward and with the surface in wave shape, the radiation area is expanded and the radiation performance is enhanced. Therefore, the unit area flow rate of the conductor is correspondingly improved. Even under the rated current of 5000A, only one copper bar is required for each phase. The size of the product is small, thereby the installation area is reduced and the installation is very convenient. The utility model is widely applicable for the power installation projects in various high-rise buildings.

Description

The heat radiating type bus duct

Technical field

The utility model relates to a kind of bus duct, particularly a kind of heat radiating type bus duct.

Background technology

The shell of bus duct in the past generally adopts steel plate to bend moulding or adopts simple aluminium alloy extrusions, poor with the bus duct heat dispersion that these two kinds of forms are made shell, for the product temperature rise is not exceeded standard, it is long-pending to strengthen cross-sectional area of conductor, every under the situation of big electric current mutually need be with two copper bars, small product size is excessive, and the user need provide extra installing space, installs extremely inconvenient.Particularly, can increase building developer's cost undoubtedly, thereby also increase user's financial burden indirectly skyscraper.

Summary of the invention

The purpose of this utility model is to provide a kind of heat radiating type bus duct of easy for installation, rapid heat dissipation.

The utility model is to realize its purpose like this:

The heat radiating type bus duct, by the dielectric film insulation, the two sides of copper bar are by insulated support and side plate insulation between the copper bar, and dielectric film is equipped with shell outward, and shell is fixed by screw and side plate, the heat sink strip of oriented outer lug on shell and/or the side plate.

The utility model is owing to the heat sink strip of oriented outer lug on shell and/or the side plate, area of dissipation enlarges, heat dispersion is improved, thereby make the unit are flow of conductor obtain corresponding raising, even under the rated current up to 5000A, every phase also only needs a copper bar, and the volume of product is little, shared installing space is also little, and it is very convenient to install.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is the enlarged drawing of C part among Fig. 1.

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated:

As shown in Figure 1, the heat radiating type bus duct is insulated by dielectric film 4 between the copper bar 3, the two sides of copper bar 3 are by insulated support 5 and side plate 7 insulation, the dielectric film 4 outer shells 2 that are equipped with, shell 2 is fixing with side plate 7 by screw 6, the heat sink strip 1 of oriented outer lug on shell 2 and/or the side plate 7.Because the heat sink strip of oriented outer lug on shell and/or the side plate, area of dissipation enlarges, heat dispersion has improved a lot, thereby make the unit are flow of conductor obtain corresponding raising, even under the rated current up to 5000A, every phase also only needs a copper bar, and the volume of product is little, shared installing space reduces, and it is very convenient to install.

For the quality that guarantees product better with reach better radiating effect, best scheme is, as Fig. 1, shown in Figure 2,1 of heat sink strip is distributed on the shell 2, and the surface 9 of heat sink strip 1 is designed to corrugated or other roughness, the surface 9 of corrugated or other roughness enlarges the area of dissipation of entire product greatly, whole like this bus duct is just sealed with side plate 7 fully by the very large shell 2 of external surface area, and area of dissipation has increased a lot, the inner heat that produces owing to the effect of big electric current of product can promptly distribute by shell 2, thereby the quality of product is guaranteed.

As shown in Figure 2, of the present utility model surperficial 9 are corrugated, and such design not only can enlarge area of dissipation, strengthen radiating effect, and appearance is very attractive in appearance again.

Claims (3)

1, heat radiating type bus duct, insulate by dielectric film (4) between the copper bar (3), the two sides of copper bar (3) are by insulated support (5) and side plate (7) insulation, the outer shell (2) that is equipped with of dielectric film (4), shell (2) is fixing by screw (6) and side plate (7), it is characterized in that the upward heat sink strip (1) of oriented outer lug of shell (2) and/or side plate (7).

2, heat radiation bus duct according to claim 1 is characterized in that described heat sink strip (1) is distributed on the shell (2).

3, heat radiation bus duct according to claim 2 is characterized in that the surface (9) of described heat sink strip (1) is corrugated.
