Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, the converter module mounting bracket includes a converter mounting base 1, a radiator mounting base 2, and a radiator base plate mounting portion 3. The converter mounting base 1 and the radiator mounting bracket 2 are oppositely arranged on two sides of the radiator substrate mounting part 3.

As shown in fig. 2, the current transformer module with a high power heat sink includes a current transformer 10, a heat dissipation substrate 30 and a heat sink 20. The heat sink 20 is large in size, and a heat sink protective cover 25 is provided outside the heat sink 20. The shape of the heat sink protective cover 25 is similar to that of the heat sink 20. The heat sink protective cover 25 has a frame slightly larger than the outer edge of the heat sink 20 and covers three side walls and the bottom surface of the heat sink 20.

The heat sink mounting base 2 includes a first top plate 21 and a first base 22. The first top plate 21 is a flat plate structure. And a plurality of radiating holes for radiating are formed in the first top plate 21, so that the working efficiency of the radiator is ensured.

The converter mount 1 includes a second top plate 11 and a second base 12. The second top plate 11 and the second base 12 have the same shape and are both square plate-like structures. The second top plate 11 serves to protect the current transformer 10. The second base 12 has a certain rigidity for carrying the current transformer 10. And the length and the width of the second base 12 are both greater than the length and the width of the current transformer 10, so that the current transformer 10 can be more conveniently installed.

The heat sink substrate mounting portion 3 has a rectangular frame structure having a through hole at the center. The current transformer 10 can enter the current transformer mounting base 1 through the through hole. The square frame structure is enclosed to close by four rigidity rectangular and forms, including two vertical frames and two horizontal frames, specifically includes: a left vertical frame 32, a right vertical frame 33, an upper horizontal frame 34, and a lower horizontal frame 35.

The second top plate 11 is perpendicular to the upper horizontal frame 34 and is connected to one side of the upper horizontal frame 34. The first top plate 21 is also perpendicular to the upper horizontal frame 34, and is provided on the other surface of the upper horizontal frame 34 opposite to the second top plate 11. And the upper surfaces of the second and first top plates 11 and 21 are flush. This is beneficial to the stability of the overall structure of the mounting bracket. The bottom plate 12 is perpendicular to the lower horizontal frame 35 and is connected to one side of the lower horizontal frame 35. The second base 12 and the first base 22 are disposed on two sides of the lower horizontal frame 35, and the upper surfaces of the second base 12 and the first base 22 are flush. This ensures that the heat sink 20 and the current transformer 10 are placed on the same plane, and the installation is more stable.

The left vertical frame 32 and the right vertical frame 33 are provided with fixing holes 31. The heat dissipating substrate 30 is fixedly connected to the heat sink substrate mounting portion 3 through the fixing hole 31, and the position of the heat sink substrate 30 is fixed.

The first top plate 21 is provided between the radiator support mounting portion 30 and the fixing frame 5. The fixed frame 5 is generally located at the bottom of the vehicle body and includes an upper frame 51 and a lower frame 52. Specifically, the first top board 21 is connected to the upper frame 51 and the upper horizontal rim 34. The first top plate 21 is further provided with an upper mounting hole 23.

Both ends of the guide rail are connected to the lower horizontal frame 35 and the lower frame 52, respectively. The bottom of the radiator guard 25 can slide on the guide rails. The converter 10 enters the converter mounting base 1 through sliding, so that manpower for mounting and overhauling can be saved, and the operation is more convenient. The top of the radiator protection cover 25 is also provided with a cover mounting hole 26. The cover mounting hole 26 is used to connect with the first top plate 21 to fix the heat sink protecting cover 25 and thus the position of the heat sink 20, so that the installation is more secure.

The two rail lengths W of the first base 22 are equal. The distance L between the two guide rails is equal to the length L' of the radiator housing 25, i.e., L ═ L. The width of the radiator cover 25 is W ', and the length W of the two guide rails is more than or equal to 1/2W'. This ensures that the center of gravity of the heat sink is positioned on the first base 22. The first base 22 is fixedly connected to the lower frame 52, and the lower frame 52 carries the main weight of the heat sink 20. Meanwhile, at least half of the volume of the radiator 20 is arranged in the mounting frame, so that the safety and the stability of the installation of the radiator 20 are ensured.
