[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a constant temperature power distribution cabinet. Background Art

[0002] Constant temperature distribution cabinet is an advanced distribution equipment that has emerged with the development of electrical equipment and automation systems. When the ambient temperature of traditional distribution cabinets fluctuates greatly, the internal electrical components are easily damaged or the performance becomes unstable. In order to improve the reliability and service life of electrical equipment, heaters, fans, temperature sensors and other devices are installed to automatically adjust the temperature inside the distribution cabinet, so that the working environment inside the distribution cabinet is maintained at a stable level, providing a strong guarantee for the stable operation of electrical equipment.

[0003] Chinese patent publication number CN214506287U discloses an automatic constant temperature distribution cabinet, which starts the fan to move hot air to the cold water tank, and then the cold water tank exchanges heat with the hot air to cool the hot air to form cold air. The cold air is then blown to various electronic components in the cabinet through the air blowing pipe and branch pipe assembly. At the same time, when the servo motor drives the screw to rotate, the slider moves, and the air blowing branch pipe moves back and forth to achieve uniform heat dissipation of the electronic components inside the cabinet. The inventor found that in actual use, there are not only various electronic components but also connecting wires in the cabinet. The air blowing pipe and branch pipe assembly are arranged in the cabinet, occupying the space of the cabinet, and the air blowing branch pipe is easy to touch the connecting wires between the electronic components when moving, causing a safety accident. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present invention provides a constant temperature power distribution cabinet, which solves the problem in the prior art that a cooling device is set inside the cabinet, which occupies the internal space of the cabinet and easily has an adverse effect on the electronic components inside the cabinet.

[0005] According to an embodiment of the present utility model, a constant temperature power distribution cabinet includes a cabinet body, an infusion pipe and a shielding assembly. One side of the cabinet body is open, and a closed door is hingedly provided at the opening. The outer cover of the cabinet body is provided with an outer shell. A hollow chamber is formed between the outer shell and the cabinet body. A plurality of middle partitions are provided at equal intervals in the hollow chamber. The middle partitions divide the hollow chamber into a plurality of channels. The channels include a first channel and a second channel. The first channel and the second channel are arranged at intervals. The infusion pipe is arranged in the first channel. A box is provided on the outer wall of the outer shell. Liquid medium is contained in the box. A delivery pump is provided in the box. One end of the infusion pipe is connected to the output end of the delivery pump, and the other end of the infusion pipe is connected to the box.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1—4, an embodiment of the present utility model proposes a constant temperature power distribution cabinet, comprising a cabinet body 1, an infusion pipe 5 and a shielding assembly. One side of the cabinet body 1 is open, and a closed door 2 is hingedly provided at the opening. The outer cover of the cabinet body 1 is provided with an outer shell 3, and a hollow chamber is formed between the outer shell 3 and the cabinet body 1. A plurality of middle partitions 4 are evenly spaced in the hollow chamber, and the middle partitions 4 divide the hollow chamber into a plurality of channels. The channels include a first channel and a second channel, and the first channel and the second channel are arranged at intervals. The infusion pipe 5 is arranged in the first channel, and a box body 6 is provided on the outer wall of the outer shell 3. The box body 6 is filled with a liquid medium, and a delivery pump is provided in the box body 6. One end of the infusion pipe 5 is connected to the output end of the delivery pump, and the other end of the infusion pipe 5 is connected to the box body 6. The shielding assembly is arranged on the top of the cabinet body 1, and the shielding assembly covers the cabinet body 1. The shielding assembly protects the entire cabinet body 1. Various electronic components are installed in the cabinet body 1. The infusion tubes 5 located in the multiple first channels can be connected to the box body 6 individually or in series. When the weather is hot in summer, the delivery pump is started. It is preferred that a temperature sensor is set in the cabinet body 1, and a controller connected to the temperature sensor electrical signal is configured to control the start of the delivery pump. The delivery pump delivers the liquid medium through the infusion tube 5. The material of the infusion tube 5 can be selected from the existing technology. The material with good thermal conductivity can be made. Through heat transfer, the liquid medium in the infusion tube 5 transfers the heat of the cabinet body 1 The liquid medium is taken away in large quantities, and eventually flows back into the box 6. The same operation is performed in the cold winter. In this embodiment, a refrigerator can be set in the box 6 to cool the liquid medium or a heater can be set to heat the liquid medium to improve the efficiency of heat transfer of the liquid medium in the infusion tube 5 and adapt to different temperature environments. In this device, the infusion tube 5 is set in the first channel and transfers the low temperature or high temperature in the cabinet by heat transfer, which will not take up space in the cabinet, can make the cabinet design more compact, and will not affect the electronic components in the cabinet, making the operation of the electronic components more stable.

[0024] like Figure 1 As shown in FIG. 2 , the cabinet further includes a fan 7, which is mounted on the housing 3. The output end of the fan 7 is connected to the second channel. An air outlet 8 connected to the second channel is provided on a side of the housing 3 away from the fan 7. The second channel is provided with a plurality of heat dissipation fins 9. During operation, the fan 7 is started and blows cold air or hot air into the second channel (the cold air or hot air is generated in conjunction with a corresponding heating device or refrigeration device as needed). When the air passes through the second channel, it transfers heat with the cabinet body 1, thereby increasing or decreasing the temperature of the cabinet body 1. When cooling is required, the heat dissipation fins 9 can accelerate the cooling efficiency.

[0025] like Figure 3As shown in FIG. 4 , a plurality of through holes 10 are further provided on one side of the second channel near the cabinet body 1. The through holes 10 connect the interior of the cabinet body 1 with the second channel, allowing air blown by the fan 7 to enter the interior of the cabinet body 1 and directly transfer heat to the electronic components inside the cabinet body 1.

[0026] like Figure 2 and 4 As shown, the shielding assembly further includes: a plurality of support columns 11, each of which is fixedly mounted on the top of the housing 3, and a shielding plate 12 mounted on the top of the support columns 11. The shielding plate 12 is mounted on the top of the housing 3 through the support columns 11 to protect the cabinet body 1 and prevent damage to the housing 3 caused by extreme weather such as hail, which may cause deformation or damage to the housing 3.

[0027] like Figure 1 As shown in FIG. 3 , further, the shielding plate 12 is in a herringbone shape. The herringbone-shaped shielding plate 12 makes it difficult for debris to accumulate on its top.

[0028] like Figure 5 As shown, further, a mounting groove is provided at the top of each support column 11, and a sliding column 13 is slidably provided in each mounting groove. The end of each sliding column 13 away from the support column 11 is fixedly connected to the shielding plate 12. A spring 14 is also provided between each support column 11 and the sliding column 13. In this embodiment, the spring 14 is provided in the mounting groove, one end of the spring 14 is fixedly connected to the bottom of the mounting groove, and the other end of the spring 14 is fixedly connected to the sliding column 13. When the shielding plate 12 is hit by a large hailstorm, the spring 14 can act as a buffer, reducing the maximum force transmitted to the cabinet body 1. When too much snow accumulates on the shielding plate 12, the staff can push the shielding plate 12 upward and then release it, allowing the snow to slide off the shielding plate 12.

[0029] like Figure 2 As shown, further, a receiving cavity is provided between the shielding plate 12 and the top of the housing 3, and the box body 6 is provided on the top of the housing 3. The box body 6 is provided on the top of the housing 3, which not only looks more beautiful but also allows the box body 6 to be protected by the shielding plate 12.

[0030] like Figure 1 As shown in FIG. 3 , an isolation frame 15 is further provided at the opening of the cabinet body 1. After the closed door 2 closes the opening of the cabinet body 1, a certain gap exists between the closed door 2 and the cabinet body 1. By providing the isolation frame 15, the isolation frame 15 closes the gap between the closed door 2 and the cabinet body 1, thereby preventing the external temperature from being transferred into the cabinet body 1 during hot seasons.

[0031] like Figure 6As shown, further, the tops of the cabinet body 1 and the outer shell 3 are each provided with a mounting slot, within which an exhaust fan 16 is disposed. In this embodiment, the provision of the exhaust fan 16 accelerates the exchange of air between the cabinet body 1 and the outside, thereby maintaining a good ventilation environment within the cabinet body 1. It should be noted that in this embodiment, the box body 6 cannot be disposed on the top of the outer shell 3 to avoid obstructing the exhaust fan 16.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
