Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1 and Figure 2, the present invention includes the mounting panel 1 that is fixed in the box body (not shown), be fixed with a plurality of flow guide bars 2 on mounting panel 1, various triangular springs are installed on flow guide bar 2, comprise strap clamp triangular spring 3, wire clamp triangular spring 4 and pipe clamp triangular spring 5.Strap clamp triangular spring 3 is installed on the front end of each flow guide bar 2, and wire clamp triangular spring 4 is installed on the tail end of outermost two flow guide bars 2, and pipe clamp triangular spring 5 is installed on the middle part of each flow guide bar 2.Diode 6 is installed between the pipe clamp triangular spring 5 of adjacent two flow guide bars 2.
In Fig. 1, embodiment shown in Figure 2, needing the quantity of the diode 6 of installing is 3, and the quantity of corresponding flow guide bar 2 is 4.All only have the installation site of a pipe clamp triangular spring on outermost left and right two flow guide bars 2 on mounting panel 1,1 pipe clamp triangular spring 5 has been installed on it; Have the installation site of two pipe clamp triangular springs on two flow guide bars 2 in the middle of on mounting panel 1,2 pipe clamp triangular springs 5 that stagger mutually in position have been installed on it.Although the shape of flow guide bar 2 is different, after fixing on mounting panel 1, between adjacent flow guide bar 2, the position of two pipe clamp triangular springs 5 close to each other is corresponding, form one group, yet staggers mutually again in the position of every group when flow guide bar 2.Accordingly, also stagger mutually in the installation site that is arranged on every group of diode 6 on pipe clamp triangular spring 5, is positioned on different straight lines, and for example in Fig. 2,3 diodes 6 are isosceles triangle and distribute.By that analogy, when the quantity of the diode 6 of installing when needs increases (but the sum of diode can only be odd number), only need a corresponding increase have the logarithm of the intermediate form flow guide bar 2 of two pipe clamp triangular spring installation sites to get final product.
As shown in Figure 1, because the pin bite of diode 6 is heat centrostigmas of flow guide bar 6, therefore two flow guide bars 2 of centre are designed to enclosure shape structure, make like this 2 paths of pin of two diodes 6 that connect on same flow guide bar longer, dispel the heat more abundant.
As shown in Figure 2, the pin of each diode 6 is all by pipe clamp triangular spring 5 clampings of both sides.But the pin of a middle diode 6 is except by 5 clampings of pipe clamp triangular spring, and the horizontal component of its pin also contacts with the top of flow guide bar 2, with flow guide bar 2, forms and is connected.By that analogy, when the quantity of the diode 6 of installing when needs increases, there is part diode 6 also can form and so contact with flow guide bar 2.
Fig. 3 shows the structure embodiment of mounting panel.The one side of mounting panel 1 is the installed surface of flow guide bar 2, comprises a plurality of installation units side by side on it, can install for a flow guide bar 2 on each installation unit.Have 1 grab 1a on outermost left and right two installation units, have 2 symmetrical grab 1a on each middle installation unit.
Fig. 4 shows the structure embodiment of flow guide bar.Corresponding with Fig. 3, be on mounting panel 1 outermost two flow guide bar 2-1,2-4 and have 1 draw-in groove 2a, have 2 draw-in groove 2a on middle flow guide bar 2-2,2-3.In conjunction with Fig. 2, when flow guide bar 2 assembled with mounting panel 1, each grab 1a inserted in corresponding draw-in groove 2a.
As shown in Figure 2, Figure 4 shows, the centre of each installation unit on mounting panel 1 is provided with a boss 1b, has the gap that Gong prizes between boss 1b and strap clamp triangular spring 3 or pipe clamp triangular spring 5., as fulcrum, can conveniently prize strap clamp triangular spring 3 and pipe clamp triangular spring 5 by boss 1b.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, within all should thinking and being included in protection scope of the present invention.
