[0009] Preferably, a sealing ring is provided on the bottom surface of the box cover, and the sealing ring is arranged along the top surface of the positioning block, and the sealing ring is located on the side of the positioning seat facing the inside of the box body.

[0010] By adopting the above technical solution, the sealing ring and the positioning block are in close contact with each other, thereby improving the sealing effect between the box cover and the box body. The positioning block provides a close contact space for the sealing ring, effectively ensuring the fitting space of the sealing ring, and fully sealing the gap between the box body and the box cover.

[0011] Preferably, a through hole for the heat sink to pass through is opened at the bottom of the box, a fixing block is arranged on the top surface of the heat sink along the outer wall of the heat sink, and the bottom surface of the fixing block is in close contact with the inner bottom surface of the box.

[0013] To sum up, the sealing ring improves the sealing between the box cover and the box body. The stepped shape of the box body facilitates the installation of the heat sink, while increasing the contact area between the heat sink and the box body, thereby improving the heat dissipation effect of the heat sink on the box body. The sealing ring effectively improves the sealing effect between the box body and the box cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0020] The present application embodiment discloses an electric control box. Figure 1 and Figure 2, including a box body 1, the top surface of the box body 1 is open, so that the installer can install various components in the box body 1. A box cover 2 is installed on the top surface of the box body 1, and the box cover 2 is used to improve the overall sealing effect of the box body 1. The bottom surface of the box body 1 is arranged in a stepped shape, so an escape space 3 is formed at the bottom of the box body 1, and a heat sink 4 located in the escape space 3 is installed at the bottom of the box body 1. The heat sink 4 is installed in the escape space 3, which can improve the space utilization efficiency on the one hand, and better heat dissipation in the box body 1 on the other hand.

[0021] Reference Figure 3 and Figure 4 In order to improve the sealing effect between the box cover 2 and the box body 1, a positioning block 5 is fixedly arranged along the outer periphery of the top surface of the box body 1, and the positioning block 5 facilitates the fixing of the box cover 2 and the box body 1. A positioning seat 6 is fixed on the top surface of the positioning block 5, and a hole for bolt positioning is provided on the top surface of the positioning seat 6. A positioning hole 7 connected to the hole of the positioning seat 6 is provided on the top surface of the box cover 2, which is convenient for tightening the bolts and fixing the box cover 2 and the box body 1. In order to further improve the sealing effect between the box cover 2 and the box body 1, a sealing ring 8 is arranged around the bottom surface of the box cover 2, and the sealing ring 8 is located in the inner range surrounded by the positioning seat 6. The sealing ring 8 is surrounded along the top surface of the positioning block 5 and is tightly attached to the top surface of the positioning block 5. When the bolts are tightened, the sealing ring 8 is squeezed and deformed by force to seal the gap between the box cover 2 and the box body 1.

[0022] Reference Figure 3 and Figure 4 The bottom of the box 1 is provided with a through hole 9 for the heat sink 4 to pass through. To facilitate the heat sink 4 to dissipate heat inside the box 1, a fixing block 10 is provided on the top surface of the heat sink 4 along the outer wall of the heat sink 4, and the bottom surface of the fixing block 10 is in close contact with the inner bottom surface of the box 1. On the one hand, the fixing block 10 seals the connection between the heat sink 4 and the box 1, and on the other hand, the fixing block 10 facilitates the installation of the heat sink 4 on the box 1, thereby improving the stability of the heat sink 4 on the box 1.

[0023] The embodiment of the present application provides an electric control box, the bottom of the box 1 is stepped, which increases the contact area between the heat sink 4 and the box 1 on the one hand, and effectively saves the installation space of the heat sink 4 on the other hand, making it easier to install the electric control box. The sealing ring 8 effectively improves the sealing effect between the box 1 and the box cover 2. The sealing ring 8 is installed on the side of the positioning seat 6 facing the inside of the box 1, reducing the influence of the positioning seat 6 on the sealing ring 8, and improving the sealing effect between the box cover 2 and the box 1. The electric control box of the present application effectively improves the heat dissipation effect and sealing effect of the internal components of the box 1.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
