As shown in Figure 1 The electric reactor is placed in the electric reactor shell, the heat-conducting silica gel is poured into the electric reactor shell, and the heat-conducting paste is coated between the electric reactor shell and the radiator contact surface. The electric reactor support plate and the radiator base plate are connected by bolts, and the heat-conducting paste between the electric reactor and the radiator contact surface is flattened. The heat generated by the electric reactor is transferred to the electric reactor shell through the heat-conducting silica gel, the electric reactor shell transfers to the heat-conducting paste, and then the heat-conducting paste transfers to the radiator base plate, and the heat is taken away.

[0007] Further, the top of the radiator is provided with a radiator base plate, and the installation slot is opened in the radiator base plate.

[0008] Further, the electric reactor fixing shell and the radiator base plate are fixed by welding or formed by casting.

[0009] Furthermore, the reactor fixing shell includes a first end plate, a second end plate, and a third end plate, a fourth end plate that are relatively arranged.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail with reference to the following embodiments.

[0025] Figure 2 FIG. 1 is an exploded view of the structure of a reactor device according to an embodiment of the present invention; FIG. Figure 2 As shown, the reactor device according to an embodiment of the present invention includes a reactor module 1, a heat sink 2 and a reactor fixing shell 34, wherein the top of the heat sink 2 is provided with a mounting slot, the reactor fixing shell 34 is installed in the mounting slot, the reactor module 1 is installed in the inner cavity of the reactor fixing shell 34, and is encapsulated by pouring a thermal conductive material; wherein the bottom of the reactor shell is an open structure, and the bottom of the reactor module 1 is in contact with the heat sink 2 through the thermal conductive material.

[0026] Based on this embodiment, by opening a mounting slot on the radiator 2, the reactor fixing shell 34 without a bottom support is inserted into the mounting slot, the reactor is directly installed in the shell, and fixed by a thermally conductive material, so that the reactor is in contact with the surface of the radiator 2 through the thermally conductive material. In this way, the heat of the reactor can be directly transferred to the radiator 2 through the thermally conductive material.

[0027] In one implementation, the reactor fixing case 34 is made of aluminum.

[0030] Specifically, the heat sink 2 includes a housing, within which a fan and cooling fins are mounted. A base plate is mounted on the top of the housing using fasteners such as bolts. This base plate has a certain thickness, allowing for mounting slots. This structure is low-cost and easy to install. Furthermore, it utilizes the structural processing of the heat sink 2 to secure the reactor mounting housing 34, simplifying the connection structure and shortening the contact path between the heat sink 2 and the reactor.

[0031] Based on the above implementation, in another implementation, the reactor fixing shell 34 is fixed to the radiator substrate 11 by welding or casting. Through this embodiment, the reactor fixing shell 34 is fixed without the need for additional fasteners such as bolts, which simplifies installation.

Specifically, the second reinforcing ribs are L-shaped, adapted to the space between the first and second end plates 11, 12, and the windings. These second reinforcing ribs are inserted into the sockets on the first and second end plates 11, 12 and then secured with a thermally conductive material. The provision of the first reinforcing ribs 31 can enhance the strength of the first and second end plates 11, 12.

[0037] Based on the above structure, in another implementation, six terminal block placement slots 21 are adaptively opened on the third end plate 13 or the fourth end plate 14 to place the terminal blocks 61 of the six reactor modules 1 .

[0038] According to another implementation of the present invention, the reactor module 1 is installed in a motor speed regulator.
