[0021] The bottom of the air guide pipe 45 is fixedly connected with the inner wall of the air guide shell 46, the bottom of the liquid storage shell 41 is fixedly connected with the top of the electrical cabinet body 1, the top of the electrical cabinet body 1 is fixedly connected with the bottom of the fan assembly 44, the end of the water return pipe 42 away from the cooling pipe 47 is fixedly connected with the inner wall of the liquid storage shell 41, the inner wall of the fan assembly 44 is fixedly connected with the output end of the double-head motor 2 away from the water pump 5 through a rotating shaft, and the top of the air guide shell 46 is fixedly connected with the bottom of the electrical cabinet body 1. Since the cooling pipe 47 is arranged near the key area of the electrical cabinet body 1 that needs to be cooled, the cooling liquid emits low-temperature air through the cooling fins during the flow process, and then flows back to the liquid storage shell 41 through the water return pipe 42. When the cooling liquid rises in temperature during the movement process, the cooling liquid in the water return pipe 42 is cooled through the cooling fins on the water return pipe 42, thereby forming a water cooling cycle and taking away part of the heat in the electrical cabinet body 1.

[0023] Working principle:

[0024] The electrical cabinet body with the double heat dissipation function mainly comprises an electrical cabinet body 1, a double-head motor 2, a filter assembly 3, a cooling assembly 4 and a water pump 5, and each part cooperates with each other, so as to realize temperature regulation of the inside of the electrical cabinet body 1 and ensure that various electrical elements in the electrical cabinet can work stably in a suitable temperature environment.

[0025] The electrical cabinet body 1 is a basic structure of the whole cabinet body, is used for accommodating various electrical elements, provides physical protection and installation space for the electrical elements, the top of the electrical cabinet body 1 is fixedly connected with the double-head motor 2 through a rack, and also provides a stable installation basis for the cooling assembly 4 and the filter assembly 3 and other related components, so that loosening and displacement of each component during the working process is avoided, and normal operation of the whole heat dissipation system is ensured.

[0026] The double-head motor 2 is installed on the top of the electrical cabinet body 1, and has two output ends, one of which is fixedly connected with the water pump 5, and the other is connected with the fan assembly 44, playing a key role in providing power for the entire heat dissipation system. The double-head motor 2 can simultaneously drive the water pump 5 and the fan assembly 44 to operate, so that the two heat dissipation modes of water cooling and air cooling can work together, thereby meeting the heat dissipation requirements of the electrical cabinet body 1 under different working conditions, and ensuring that the heat in the cabinet body can be dissipated.

[0027] The filtering assembly 3 is located outside the cooling assembly 4 and is fixedly connected with the cooling assembly 4. The main function of the filtering assembly 3 is to prevent foreign matters from entering the electrical cabinet body 1, so as to avoid affecting the performance of electrical elements and the heat dissipation effect due to the accumulation of foreign matters. The fixed shell 31 serves as the main structure of the filtering assembly 3, and the inner wall thereof is fixedly connected with the outer wall of the air guide square tube 32. The air guide square tube 32 plays a role in guiding the flow direction of air. The fixed cover 33 is fixedly connected to the top of the air guide square tube 32. The baffle 34 is fixedly connected to the inner wall of the fixed cover 33. The baffle 34 can block and guide the air to a certain extent. The filter plate 35 is fixedly installed on the top of the baffle 34. The filter plate 35 can filter out dust, impurities and other small particles in the air. When external air enters the electrical cabinet under the suction of the fan assembly 44, the air will first pass through the filtering assembly 3, be filtered by the filter plate 35, and then be blocked and guided by the baffle 34, so that the air entering the electrical cabinet body 1 is relatively clean, creating a good environment for the subsequent heat dissipation process.

[0028] The cooling assembly 4 is installed on the top of the electrical cabinet body 1, and undertakes the important task of reducing the temperature in the electrical cabinet body 1 by combining water cooling and air cooling. The liquid storage shell 41 is a key part of the cooling assembly 4, and stores cooling liquid therein. The inner wall of the liquid storage shell 41 is fixedly connected with the water outlet end of the cooling pipe 47 through the water return pipe 42. The water inlet end of the cooling pipe 47 is fixedly connected with the water outlet pipe 43. When the water pump 5 is working, the cooling liquid in the liquid storage shell 41 is transported to the water pump 5 through the connecting pipe, and then pumped to the water outlet pipe 43 by the water pump 5. The water outlet pipe 43 is transported to the cooling pipe 47. The cooling liquid circulates in the cooling pipe 47. Since the cooling pipe 47 is laid near the key area of the electrical cabinet body 1 that needs to be cooled, the cooling liquid emits low-temperature air through the cooling fins during the flow process. The cooling liquid is returned to the liquid storage shell 41 through the water return pipe 42. During the movement of the cooling liquid, the temperature rises, and when it flows back through the water return pipe 42, the cooling fins on the water return pipe 42 cool the cooling liquid in the water return pipe 42, thereby forming a water cooling cycle and taking away part of the heat in the electrical cabinet body 1.

[0029] At the same time, the outer wall of the cooling pipe 47 is fixedly connected with the air guide shell 46, the inner wall of the air guide shell 46 is fixedly connected with the fan assembly 44 through the air guide pipe 45, when the double-head motor 2 drives the fan assembly 44 to rotate, the fan assembly 44 will generate suction, so that the air filtered by the filtering assembly 3 through the air guide square pipe 32 enters the air guide shell 46, under the guidance of the air guide shell 46, the air flows along the outer wall of the cooling pipe 47, on the one hand, the cooling liquid in the cooling pipe 47 can be further cooled, and the heat dissipation of the cooling liquid is accelerated, on the other hand, when the air flows through the inside of the electrical cabinet body 1, the heat emitted by the electrical elements in the cabinet space is also taken away, then the hot air is discharged from the electrical cabinet body 1 under the action of the fan assembly 44, forming a wind cooling heat dissipation process, the wind cooling and the water cooling cooperate with each other to reduce the temperature inside the electrical cabinet body 1, ensure that the inside of the cabinet is in a suitable temperature range, and ensure the normal operation of the electrical elements.

[0030] In the whole working process of the electrical cabinet body, the filtering assembly 3 filters the air outside, then the cooling assembly 4 is driven by the double-head motor 2 and cooperated with the water pump 5, the inside of the electrical cabinet body 1 is cooled by the double heat dissipation modes of water cooling and wind cooling, each assembly is closely matched according to the above working principle, and the stable play of the heat dissipation function of the electrical cabinet body is guaranteed, and the requirements of the electrical elements on the temperature environment under different working conditions are met.

[0031] Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled in the art and related fields without creative labor should belong to the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model, if no special description and limitation, are implemented according to the conventional means in the art.
