[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 5 The waterproof electrical control box for cold storage shown includes a control box body 1. A sealing cover 2 is rotatably connected to the front side of the control box body 1. A sealing protrusion 14 is fixedly connected to the front edge of the control box body 1. A sealing groove 24 is opened at the rear edge of the sealing cover 2. The sealing protrusion 14 is inserted into the interior of the sealing groove 24. A sealing strip is fixedly connected to the inner wall of the sealing groove 24. Two sets of wiring holes 18 are opened on the lower surface of the sealing cover 2. A sealing assembly is provided inside the wiring hole 18. The sealing assembly includes a waterproof connector 4, a first locking block 41, a first sealing ring 43, a second sealing ring 44, and a second locking block 45. The interior of the waterproof connector 4 is filled with sealant. The waterproof connector 4 is inserted into the interior of the wiring hole 18. A wire 42 is inserted into the interior of the waterproof connector 4. The first locking block 41 is fixedly connected to the lower end of the waterproof connector 4. The second locking block 45 is threadedly connected to the upper end of the waterproof connector 4. The first sealing ring 43 and the second sealing ring 44 are both sleeved on the outside of the waterproof connector 4.

[0033] When the sealing cover 2 is closed with the electrical control box body 1, the sealing protrusion 14 is inserted into the sealing groove 24 and squeezes the sealing strip inside the sealing groove 24, causing the sealing strip to extend to both sides and make close contact with the side wall of the sealing groove 24 and the surface of the sealing protrusion 14, effectively improving the sealing performance at the connection between the sealing cover 2 and the electrical control box body 1.

[0034] Meanwhile, when the wire 42 is routed into the interior of the electrical control box body 1, the wire 42 is first inserted into the interior of the waterproof connector 4 from the lower end of the waterproof connector 4. After leaving a certain length of wire 42, the interior of the waterproof connector 4 is filled with sealant to seal the connection between the wire 42 and the waterproof connector 4. Then, the first sealing ring 43 is fitted onto the surface of the waterproof connector 4. Next, the upper end of the wire 42 and the waterproof connector 4 are inserted into the interior of the wiring hole 18. At this time, the first sealing ring 43 is in contact with the bottom wall of the electrical control box body 1. Then, the second sealing ring 44 is fitted onto the upper end of the waterproof connector 4. At this time, the second sealing ring 44 is in contact with the inner bottom wall of the electrical control box body 1. Next, the second locking block 45 is threadedly connected to the upper end of the waterproof connector 4. At the same time, the first locking block 41 and the second locking block 45 rotate in opposite directions to tightly fix the waterproof connector 4 and the second locking block 45, thereby compressing and sealing the first sealing ring 43 and the second sealing ring 44 and improving the sealing performance at the wiring hole 18.

[0035] See Figure 3 and Figure 4 A first connecting plate 13 is fixedly connected to the left side surface of the electrical control box body 1, and two sets of second connecting plates 23 are fixedly connected to the left side surface of the sealing cover plate 2. The first connecting plate 13 and the second connecting plate 23 are rotatably connected. A first connecting block 11 is fixedly connected to each of the four corners of the electrical control box body 1. A threaded hole 12 is opened inside the first connecting block 11. A second connecting block 21 is fixedly connected to each of the four corners of the sealing cover plate 2. A connecting hole 22 is opened inside the second connecting block 21. A fixing screw 25 is inserted into the connecting hole 22. One end of the fixing screw 25 is threadedly connected to the threaded hole 12.

[0036] In addition, during the process of connecting the sealing cover 2 to the electrical control box body 1, the sealing cover 2 will be rotated to the front side of the electrical control box body 1 through the cooperation of the first connecting plate 13 and the second connecting plate 23. Then, the fixing screw 25 will be threaded through the connecting hole 22 and the threaded hole 12 to lock and fix the sealing cover 2 to the electrical control box body 1, thereby improving the firmness of the connection.

[0037] See Figure 2 and Figure 4 An installation plate 15 is fixedly connected to the rear inner wall of the electrical control box body 1. Multiple sets of heat conduction plates 16 are fixedly connected to the inner walls of the left and right sides of the electrical control box body 1. Multiple sets of heat dissipation fins 17 are fixedly connected to the sides of the heat conduction plates 16. An exhaust duct 3 is fixedly connected to the upper end of the electrical control box body 1. Exhaust ports are opened at both ends of the exhaust duct 3. An air inlet duct 31 is fixedly connected to the middle of the exhaust duct 3.

[0038] It should be added that the heat-conducting plate 16 is made of copper, which has strong thermal conductivity. In actual use, when the internal equipment generates heat, the heat-conducting plate 16 conducts the heat generated by the internal components to the surface of the heat dissipation fins 17. At this time, the fan inside the air inlet duct 31 delivers airflow to the inside of the exhaust duct 3, and then sprays it out from the exhaust ports at both ends, accelerating the airflow speed on the surface of the heat dissipation fins 17 and quickly dissipating the heat. This ensures the internal sealing of the electrical control box body 1 while effectively improving its internal heat dissipation, and the manufacturing cost is low.

[0039] The working principle of this utility model is as follows: The sealing ridge 14 is inserted into the sealing groove 24 to seal the connection between the sealing cover plate 2 and the electrical control box body 1. At the same time, the first locking block 41 and the second locking block 45 work together with two sets of sealing rings to press and seal the upper and lower sides of the cable hole 18. The interior of the waterproof connector 4 is filled with sealant to effectively seal the cable hole 18, thereby improving the equipment's sealing performance, preventing moisture from entering the interior of the electrical control box body 1, and improving the safety of the internal components. At the same time, the heat-conducting plate 16 and the heat dissipation fins 17 effectively dissipate heat from the interior of the electrical control box body 1.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
