It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an explosion-proof electrical control cabinet, including a control cabinet body 1, a support frame 2 is fixedly connected to the bottom of the inner wall of the control cabinet body 1, a water tank 3 is fixedly installed between the inner walls of the support frame 2, a heat sink 4 is fixedly connected to the bottom of the water tank 3, a connecting pipe 5 is fixedly connected to the output end of the water tank 3, a water pump 6 is fixedly connected to the output end of the water pump 6, a cooling pipe 7 is fixedly connected to the input end of the water tank 3 and the output end of the cooling pipe 7, a heat dissipation hole 8 is opened at the bottom of the control cabinet body 1, a first heat dissipation fan 9 is fixedly inserted into the inner wall of the heat dissipation hole 8, a partition 10 is fixedly installed on the inner wall of the control cabinet body 1, a heat conducting plate 11 is fixedly connected to one side of the outer wall of the control cabinet body 1, and two exhaust holes 12 are opened at the top of the control cabinet body 1, and second heat dissipation fans 13 are fixedly inserted into the inner walls of the two exhaust holes 12.

[0024] The effect achieved by the entire embodiment 1 is that, during the use of the control cabinet, firstly, a proper amount of coolant is injected into the water tank 3, and then the water pump 6 is started. After the water pump 6 is started, the coolant in the water tank 3 is extracted and pressurized to make it flow in the curved cooling pipe 7. At this time, the heat of the control cabinet body 1 is transferred to the cooling pipe 7 through the heat conducting plate 11. Since the cooling pipe 7 is fixedly connected to one side of the outer wall of the heat conducting plate 11, the coolant absorbs the heat when flowing inside the cooling pipe 7, thereby reducing the temperature of the control cabinet body 1, and the heat conducting plate 11 is fixedly installed on the back of the control cabinet body 1, which effectively dissipates the temperature of the side where the electrical components are installed, thereby ensuring the normal operation of the electrical components. Operation and extended service life, the coolant after absorbing heat then flows back to the water tank 3, at this time start the first cooling fan 9, and dissipate heat through the heat sink 4 at the bottom of the water tank 3, the wind flow generated after the first cooling fan 9 is started forces the heat sink 4 to cool the coolant, thereby further reducing the temperature of the coolant, and through the continuous circulation of the water pump 6, the coolant continuously circulates between the cooling pipe 7 and the water tank 3, thereby achieving continuous heat dissipation of the control cabinet body 1, in addition, after starting the second cooling fan 13, it uses the heat exchange principle to assist in heat dissipation, and acts together with the coolant heat dissipation on the control cabinet body 1, further improving the heat dissipation effect and ensuring the stable operation of the control cabinet.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, two dust cover plates 14 are fixedly installed on the top of the control cabinet body 1, a group of ventilation holes 15 are opened on one side of the outer wall of the control cabinet body 1, a protective cover 16 is fixedly installed on one side of the outer wall of the control cabinet body 1, a first clamping plate 17 is fixedly installed on one side of the outer wall of the control cabinet body 1, and a filter screen 18 is movably inserted into the inner surface wall of the first clamping plate 17, two mounting plates 19 are fixedly installed on one side of the outer wall of the control cabinet body 1, a slide groove 20 is opened on one side of the outer wall of the two mounting plates 19, a spring 21 is fixedly connected to the bottom of the inner wall of the two slide grooves 20, a slider 22 is slidably embedded in the inner surface wall of the two slide grooves 20, a second clamping plate 23 is fixedly connected between one side of the outer wall of the two sliders 22, and a pull block 24 is fixedly installed on one side of the outer wall of the second clamping plate 23.

[0026] The effect achieved by the entire embodiment 2 is that a protective cover 16 is fixedly installed on one side of the outer wall of the control cabinet body 1, and the protective cover 16 can prevent some dust from entering the control cabinet body 1 through the ventilation holes 15, thereby ensuring the cleanliness of the internal environment of the controller, and a filter screen 18 is arranged on the other side of the outer wall of the control cabinet body 1. The main function of the filter screen 18 is to block and capture dust particles in the air, thereby maintaining the cleanliness of the air inside the control cabinet. When the filter screen 18 is full of dust due to long-term use and needs to be cleaned or replaced, first pull the pull block 24 to move it downward, and this action will prompt the second clamping plate 23 to move downward and squeeze the two The filter 18 is released by the spring 21 as the second card plate 23 moves downward, and the filter 18 originally inserted in the first card plate 17 is released. At this time, the filter 18 can be easily taken out. After the filter 18 is thoroughly cleaned and dried, one end of it is reinserted into the first card plate 17. Then, the pull block 24 is released, and the two springs 21 will push the second card plate 23 upward under their own elastic force, and re-fix the filter 18 between the first card plate 17 and the second card plate 23, thereby completing the reinstallation and fixation of the filter 18. This process ensures the stability and filtering effect of the filter 18, and also facilitates the maintenance and operation of the user.

[0027] Working principle: After the equipment is powered on, first inject an appropriate amount of coolant into the water tank 3. Then, the staff starts the water pump 6 and the first cooling fan 9 through the control system. After the water pump 6 is started, the motor drives the impeller to rotate to generate centrifugal force, thereby extracting the coolant inside the water tank 3, and the impeller inside the pump body rotates to generate pressure to pressurize the coolant. The pressurized coolant then flows inside the curved cooling pipe 7. The cooling pipe 7 is in close contact with the control cabinet body 1 through its built-in heat conduction plate 11, thereby effectively absorbing the heat generated by the control cabinet body 1. The coolant in the cooling pipe 7 When flowing, the heat on the heat conducting plate 11 is taken away by the heat exchange principle to realize the cooling of the control cabinet body 1. The cooling pipe 7 is made of copper alloy. This material has excellent thermal conductivity and can quickly and effectively transfer heat. The coolant after absorbing heat flows back to the water tank 3 through the return path of the cooling pipe 7, ready for the next round of circulation. At this time, the first cooling fan 9 generates airflow after starting, and performs forced convection heat dissipation through the heat sink 4 at the bottom of the water tank 3. At the same time, the airflow generated by the first cooling fan 9 blows directly to the heat sink 4, accelerating the heat dissipation of the heat on the heat sink 4 to the surrounding environment In order to further reduce the temperature of the coolant, at the same time, the control system starts the second heat dissipation fan 13, and the second heat dissipation fan 13 extracts the hot air inside the control cabinet body 1 through the heat exchange principle, and exchanges heat with the low-temperature air of the external environment to reduce the internal temperature of the control cabinet body 1. This heat dissipation method cooperates with the coolant heat dissipation to achieve efficient heat dissipation of the control cabinet, and the water tank 3 and the control cabinet body 1 shell are made of stainless steel with good thermal conductivity, so that the water tank 3 and the control cabinet body 1 shell have good thermal conductivity, and the filter 18 is used to The filter 18 is used to filter impurities in the air and prevent them from entering the control cabinet body 1. When the filter 18 needs to be replaced or cleaned, the pull block 24 only needs to be pulled downward to move the second clamping plate 23 downward and squeeze the two springs 21. The downward movement of the second clamping plate 23 will release the fixation of the filter 18, thereby allowing the filter 18 to be taken out. After cleaning the filter 18, one end of it is reinserted into the first clamping plate 17, and the pull block 24 is released. Under the elastic force of the two springs 21, the second clamping plate 23 will fix the filter 18 again, completing the replacement or cleaning process of the filter 18.
