The case where resistance.
Further, it is attached between the copper pedestal and the copper bar by screw threads for fastening structure.Screw threads for fastening
Structure installation and removal are convenient, convenient for setting.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the embodiment 1 of the copper bar bridging arrangement of the utility model；
Fig. 2 is the top view of Fig. 1；
In figure: 1- copper bar, 2- pedestal, 3- cooling fin, 4- fastening bolt.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment 1 of the copper bar bridging arrangement of the utility model:
As shown in Figure 1 and 2, copper bar bridging arrangement includes mutual overlapped two copper bars 1, and copper bar is taken in other embodiments
Binding structure also may include three or more mutually overlapped copper bars.Copper bar bridging arrangement further includes being separately mounted to corresponding copper bar 1
Two copper bar radiators of lateral surface, copper bar radiator include pedestal 2, and pedestal 2 is plate in the present embodiment, in other embodiments
The other shapes such as middle pedestal 2 or semi-cylindrical, hemisphere.The side of pedestal 2 is formed for fitting with 1 surface of copper bar
Binding face, the other side of pedestal 2 is provided with multiple cooling fins 3, and multiple 3 parallel intervals of cooling fin are fixed on the side of pedestal 2
On.It is attached between copper bar 1 and copper bar radiator by screw threads for fastening structure.
In the present embodiment, the making material of pedestal 2 and cooling fin 3 is copper product in copper bar radiator, avoids copper bar
Due to there is the case where potential difference using different materials between radiator and copper bar 1, copper bar will lead in the presence of potential difference
Micro-cell corrosion effect is generated between radiator and copper bar 1, so that the contact surface of copper bar 1 and copper bar radiator showing of occurring corroding
As, and then will lead to contact resistance between copper bar 1 and copper bar radiator and increase, it is unfavorable for the heat dissipation of copper bar 1.By the way that copper bar is dissipated
Hot device eliminates the hidden danger of potential difference using material identical with copper bar 1, saves electric energy to a certain extent, improves electric energy
Transformation efficiency.It should be noted that in other embodiments, cooling fin 3 can also be using good materials of other thermal conductivity such as aluminums
Material.
Each cooling fin 3 is wedge shape in the present embodiment, and the wedge-shaped biggish side in cooling fin cross section is connected with pedestal 2
It connects, designs by using this structure, so that the loss law of the radiating of cooling fin 3 and heat is adapted, due to more leaning on
1 heat of nearly copper bar is more, and the cooling fin area of section close to 1 side of copper bar is larger also with better heat dissipation effect.
Screw threads for fastening structure includes fastening bolt 4 and the bolt mounting holes that cooperate with fastening bolt 4, two in the present embodiment
