Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical control box technology, specifically to an outdoor waterproof and dustproof water pump electrical control box. Background Technology
[0002] The primary method for cooling electrical control boxes is through the proper design of heat sinks and vents, utilizing natural convection to expel heat from the box. This method requires no additional energy consumption, but its cooling effect is limited and it is suitable for environments with minimal temperature fluctuations. Alternatively, fans or air duct systems can be used to introduce outside air into the distribution box to accelerate heat dissipation. While fans offer improved operational stability and lifespan, proper maintenance and replacement are still necessary.
[0003] For electrical control boxes installed in the field, waterproof and dustproof design is required. However, after the electrical control box is designed to be waterproof and dustproof, it cannot have air convection with the outside, resulting in the inability to dissipate heat inside the electrical control box. Utility Model Content
[0004] In order to solve the technical problems in the existing technology, such as the inability to allow air convection between the waterproof and dustproof design of the electrical control box and the inability to dissipate heat inside the electrical control box, this utility model provides an outdoor waterproof and dustproof water pump electrical control box.

[0006] An outdoor waterproof and dustproof water pump control box includes a box body with a sealed cavity structure. The sealed cavity of the box body includes two independent receiving chambers, namely a device mounting chamber and a heat dissipation chamber. The device mounting chamber is equipped with a first heat exchange pipe, and the heat dissipation chamber is equipped with a second heat exchange pipe, a water pump, and a water tank. One end of the first heat exchange pipe is inserted into the heat dissipation chamber from the device mounting chamber and connected to one end of the second heat exchange pipe. The other end of the second heat exchange pipe is connected to the water inlet of the water pump. The water outlet of the water pump is connected to the water tank. The other end of the first heat exchange pipe is inserted into the heat dissipation chamber from the device mounting chamber and connected to the water tank. An air inlet and an air outlet communicating with the heat dissipation chamber are opened on the box body. A blower device is fixedly connected to the box body at the air inlet.
[0007] The beneficial effects of this utility model are as follows: By setting two independent sealed spaces inside the electrical control box, namely the device mounting chamber and the heat dissipation chamber, after the electrical control device is installed in one of the sealed spaces, namely the device mounting chamber, the heat in the device mounting chamber can be transferred to the second heat exchange pipe in the heat dissipation chamber through the flowing cooling water of the first heat exchange pipe. Heat exchange takes place in the heat dissipation chamber through the second heat exchange pipe, thereby reducing the heat in the device mounting chamber.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, both the first heat exchange tube and the second heat exchange tube are serpentine copper tubes.
[0010] The beneficial effect of adopting the above-mentioned further solution is that by setting the first heat exchange tube and the second heat exchange tube as serpentine copper tubes, the contact area between the copper tubes and the air is increased, thereby improving the heat exchange efficiency.
[0011] Furthermore, both the first heat exchange tube and the second heat exchange tube are provided in multiples, with each of the multiple first heat exchange tubes corresponding to one of the multiple second heat exchange tubes.
[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting multiple first heat exchange tubes and multiple second heat exchange tubes, the heat dissipation efficiency is improved.
[0013] Furthermore, the device mounting compartment is also equipped with a device mounting rack, which is fixedly connected to the housing.

[0016] The advantage of adopting the above-mentioned further solution is that by opening multiple device mounting slots on the device mounting rack, it is convenient to install the electrical control device on the device mounting rack by inserting screws through the device mounting slots.
[0017] Furthermore, the first heat exchange tube is fitted with a waterproof ring, which is embedded in the housing.
[0018] The advantage of adopting the above-mentioned further solution is that by providing a waterproof ring on the outer sleeve of the first heat exchange tube, it is possible to prevent water vapor in the heat dissipation chamber from flowing into the device mounting chamber from the first heat exchange tube.
[0019] Furthermore, the heat dissipation chamber is equipped with a self-regulating valve. One end of the self-regulating valve is connected to the device mounting chamber through a pipe, and the other end of the self-regulating valve is connected to the heat dissipation chamber.
[0020] The beneficial effect of adopting the above-mentioned further solution is that by setting a self-regulating valve, the air pressure in the device installation chamber can be automatically adjusted to prevent the air pressure difference between the device installation chamber and the outside from being too large, which could lead to deformation or damage to the chamber.

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0033] like Figure 1 As shown, this utility model embodiment provides an outdoor waterproof and dustproof water pump electrical control box, including a box body 1 with an internal sealed cavity structure. The internal sealed cavity of the box body 1 includes two independent receiving cavities, namely a device mounting chamber 3 and a heat dissipation chamber 6. The device mounting chamber 3 is provided with a first heat exchange pipe 4, and the heat dissipation chamber 6 is provided with a second heat exchange pipe 7, a water pump 10, and a water tank 11. One end of the first heat exchange pipe 4 is inserted into the heat dissipation chamber 6 from the device mounting chamber 3 and connected to one end of the second heat exchange pipe 7. The other end of the second heat exchange pipe 7 is connected to the water inlet of the water pump 10. The water outlet of the water pump 10 is connected to the water tank 11. The other end of the first heat exchange pipe 4 is inserted into the heat dissipation chamber 6 from the device mounting chamber 3 and connected to the water tank 11. An air inlet 8 and an air outlet 14 communicating with the heat dissipation chamber 6 are opened on the box body 1. A blower 9 fixedly connected to the box body 1 is provided at the air inlet 8. A maintenance window 2 is provided on the enclosure 1, which is connected to the component mounting compartment 3. A door 12 is installed at the maintenance window 2, and one side of the door 12 is hinged to the enclosure 1. A waterproof and dustproof seal is installed on the window of the maintenance window 2 or on the door 12. The component mounting compartment 3 and the heat dissipation compartment 6 are divided into the internal cavity of the enclosure 1 by a partition. Cooling water stored in the water tank 11 flows sequentially through the first heat exchange pipe 4 and the second heat exchange pipe 7 under the negative pressure of the water pump 10, then flows back to the water tank 11. Ventilation holes or slots are provided on the water tank 11 to facilitate communication between the cooling water inside and the atmosphere. In practice, the water pump 10 can be fixed to the water tank 11 with screws, and the water tank 11 can be fixed inside the enclosure 1.
[0034] By setting two independent sealed spaces inside the electrical control box, namely the device mounting chamber 3 and the heat dissipation chamber 6, after the electrical control device is installed in one of the sealed spaces, namely the device mounting chamber 3, the heat in the device mounting chamber 3 can be transferred to the second heat exchange pipe 7 in the heat dissipation chamber 6 through the flowing cooling water of the first heat exchange pipe 4. Heat exchange takes place in the heat dissipation chamber 6 through the second heat exchange pipe 7, so that the heat in the sealed device mounting chamber 3 can be dissipated in the heat dissipation chamber 6 through the cooling water, thereby reducing the heat in the device mounting chamber 3.
[0035] In some embodiments, both the first heat exchange tube 4 and the second heat exchange tube 7 are serpentine copper tubes. Multiple first heat exchange tubes 4 and multiple second heat exchange tubes 7 are provided, with each multiple first heat exchange tube 4 corresponding to one of the multiple second heat exchange tubes 7. One end of the first heat exchange tube 4 passes through a partition and connects to one end of the second heat exchange tube 7; the other end of the first heat exchange tube 4 passes through the partition and connects to the water tank 11.
[0036] By setting the first heat exchange tube 4 and the second heat exchange tube 7 as serpentine copper tubes, the contact area between the copper tubes and the air is increased, thereby improving the heat exchange efficiency; by setting multiple first heat exchange tubes 4 and multiple second heat exchange tubes 7, the heat dissipation efficiency is improved.
[0037] In some embodiments, the device mounting compartment 3 is further provided with a device mounting rack 5, which is fixedly connected to the housing 1. The device mounting rack 5 is an arc-shaped support. By providing the device mounting rack 5, it is convenient to install electrical control devices on the device mounting rack 5.
[0038] like Figure 2 As shown, in some embodiments, the device mounting bracket 5 has multiple device mounting slots 13. All device mounting slots 13 are located on the arched back of the bow-shaped structure of the device mounting bracket 5, and all slots 13 penetrate the arched back of the device mounting bracket 5. By having multiple device mounting slots 13 on the device mounting bracket 5, it is convenient to install the electronic control device on the device mounting bracket 5 by inserting screws or bolts through the slots 13. Simultaneously, multiple first heat exchange pipes 4 are respectively arranged on both sides of the device mounting bracket 5 to prevent the first heat exchange pipes 4 from obstructing the installation of the electronic control device.
[0039] The first heat exchange tube 4 is fitted with a waterproof ring 20. A tube hole 19 is opened on the partition plate, and the waterproof ring 20 is set at the tube hole 19 and embedded in the partition plate. Both ends of the first heat exchange tube 4 pass through the tube hole 19 through the waterproof ring 20. By fitting the first heat exchange tube 4 with a waterproof ring 20, it is possible to prevent water vapor in the heat dissipation chamber 6 from flowing into the device mounting chamber 3 from the first heat exchange tube 4.
[0040] In some embodiments, the heat dissipation chamber 6 is equipped with a self-regulating valve 18. One end of the self-regulating valve 18 is connected to the device mounting chamber 3 via a pipe, and the other end of the self-regulating valve 18 is connected to the heat dissipation chamber 6. By setting the self-regulating valve 18, the air pressure inside the device mounting chamber 3 can be automatically adjusted to prevent the air pressure difference between the device mounting chamber 3 and the outside from being too large, which could cause deformation or damage to the housing 1.
[0041] like Figure 3 As shown, in some embodiments, a water supply valve 17 is connected to the water tank 11. One end of the water supply valve 17 is connected to the water tank 11 via a water supply pipe 16, and the other end of the water supply valve 17 is connected to a tap water pipe. By setting the water supply valve 17, tap water can be added to the water tank when the water level is low. An exhaust dustproof net 15 is provided at the air outlet 14, and the exhaust dustproof net 15 is fixedly connected to the housing 1. The air outlet 14 is arranged opposite to the air inlet 8.
[0042] like Figure 4 As shown, in some embodiments, the air blowing device 9 sequentially includes a fan fixing block 906, a cooling fan 905, and a dustproof mesh mounting block 901. The fan fixing block 906 is fixedly connected to the housing 1. A second ventilation hole 907 is opened on the fan fixing block 906. The second ventilation hole 907 is a through hole and communicates with the air inlet 8. The cooling fan 905 is disposed at the second ventilation hole 907 and is fixed to the fan. The dustproof net mounting block 901 is fixedly connected to the dustproof net mounting block 906. A first ventilation hole 902 is opened on the dustproof net mounting block 901. The first ventilation hole 902 is a through hole. The dustproof net mounting block 901 is fixedly connected to the cooling fan 905. The dustproof net mounting block 901 is provided with an air inlet dustproof net 904. The dustproof net mounting block is provided with a dustproof net mounting groove 903. The dustproof net mounting groove 903 is connected to the first ventilation hole 902. The air inlet dustproof net 904 is inserted and matched with the dustproof net mounting groove 903. Specifically, a first ventilation hole 902 is opened on one end face of the dustproof net mounting block 901, and the other end of the dustproof net mounting block 901 is fixed to the cooling fan 905. The first ventilation hole 902 is connected to the air inlet of the cooling fan 905. The dustproof net mounting groove 903 is located on the side of the dustproof net mounting block 901 and is perpendicular to the first ventilation hole 902. After the air inlet dustproof net 904 is inserted into the dustproof net mounting groove 903, the air inlet dustproof net 904 just blocks the first ventilation hole 902, so that the air can be filtered by the air inlet dustproof net 904 after entering from the first ventilation hole 902.
