[0001] The invention relates to the technical field of control cabinets, in particular to an electrical automation control box for a logistics cold storage. Background Art

[0002] The electrical control box of the logistics cold storage is a professional control device for cold storage, which can detect and adjust the environmental parameters in the cold storage, and its structure is very complex. At present, although the existing electrical control boxes of logistics cold storage meet the needs of logistics cold storage environmental control to a certain extent, there are still some major defects.

[0003] First, the sealing performance is poor. Due to the harsh working environment, if the sealing performance of the electric control box is not good, it is easy for water or dust to enter, causing damage to the internal electrical components or short circuits.

[0004] Secondly, it is susceptible to environmental influences. Environmental factors such as temperature and humidity have a significant impact on the working state and service life of the electric control box. If the ambient temperature is too high or the humidity is too high, it will damage the electric control box. In order to ensure freshness, logistics cold storage often works continuously throughout the year, and the electrical automation control box of the logistics cold storage also works at high load for a long time. The long-term accumulation of environmental influences can easily increase the failure rate of the control box.

[0005] Therefore, there is an urgent need for a new type of electrical automation control box for logistics cold storage to provide an effective solution to the defects of the existing technology. Summary of the invention

[0006] The purpose of the present invention is to provide an electrical automation control box for a logistics cold storage to solve the problems raised in the above background technology.

[0035] A start-stop valve 25 is provided in the air intake pipe 16 . The start-stop valve 25 includes a retaining ring provided on the inner wall of the circumference of the air intake pipe 16 , and a sealing cover 26 is rotatably connected above the retaining ring.

[0036] The left side of the heat conducting fin 20 is arranged horizontally, and the right side of the heat conducting fin 20 is provided with an inclined piece 21 extending toward the air inlet 17 . All the inclined pieces 21 are distributed in a fan shape on the left side of the air inlet 17 , and the ends of all the inclined pieces 21 form an arc-shaped uniform air outlet 19 .

[0037] An air outlet dustproof net 24 is installed on the air outlet 23 , and an air inlet dustproof net 18 is detachably installed on the air inlet 17 .

[0038] A concave door groove 7 is provided on the front end of the box body 1, and a door 10 is rotatably installed in the door groove 7. A sealing ring groove is provided in the door groove 7, and a sealing ring 8 is installed in the sealing ring groove. After the door 10 is closed, the internal space of the box body 1 is isolated from the external space.

[0039] A threading hole 4 is provided on the bottom side wall of the box body 1 , and the wires connected to the electrical control element 2 pass through the threading hole 4 , and a sealing plug 5 with a cylindrical structure is clamped between the threading hole 4 and the wires.

[0040] A concave cover groove 9 is provided on the front side of the door groove 7 , and a transparent cover 13 is rotatably mounted in the cover groove 9 .

[0041] A heat-conducting silicone cloth insulating sheet is bonded between the outer surface of the rear side wall of the box body 1 and the heat-conducting fins 20 .

[0042] The outer surfaces of the pipe joint 15 and the air intake pipe 16 are coated with a heat-insulating layer.

[0043] Working principle of this embodiment:

[0044] The electrical control elements 2 in the control box are connected in order through the harness trough 3, which are responsible for detecting environmental parameters such as temperature and humidity in the cold storage, and automatically adjusting the operating state of the cold storage according to preset conditions. These operations can be manually monitored and adjusted through the control buttons 12 and the instrument panel 11 on the door 10. Under normal circumstances, the door 10 is closed, so that the box body 1 forms a sealed space, which is not easily affected by the external environment. Although the box body 1 is a sealed space after the door 10 is closed, the physical control room 14 is used to absorb the heat generated by the internal components of the box body 1 to reduce the direct impact of the external environment on the electrical control elements 2. When the temperature inside the box body 1 rises, the heat-conducting fins 20 in the physical control room 14 can absorb part of the heat. Under the negative pressure formed by the temperature difference, the cold air sucked from the inside of the cold storage through the air inlet pipe 16 flows through the heat-conducting fins 20 relative to the air with a lower temperature inside the box, takes away the heat, and discharges it through the air outlet 23, which helps to reduce the temperature inside the box body 1 and keep the electrical control elements 2 in a suitable working environment.

[0045] This embodiment effectively prevents the entry of water and dust through the reasonable design of the box body 1 and the sealing structure of the box door 10, protects the internal electrical control components 2 from damage, and prolongs the service life of the control box. The physical control chamber 14 enables the control box to dissipate heat from the box body 1 in a physical way without energy consumption and the action of additional components, effectively reducing the impact of environmental factors on the electrical control components 2 and reducing the failure rate. The difference in area between the air inlet 17 and the air outlet 23 and the dense distribution of the heat-conducting fins 20 make the heat exchange process in the physical control chamber 14 more efficient. This helps to quickly adjust the temperature inside the control box and keep it in the best working condition.

[0046] This embodiment effectively solves the problems existing in the prior art and improves the sealing performance, environmental adaptability and heat dissipation performance of the control box without adding additional electrical components.

[0047] The start-stop valve 25 is composed of a retaining ring and a sealing cover 26, and is installed in the air intake pipe 16. When the heat generation of the box body 1 is small, a small negative pressure is generated in the air intake pipe 16 due to the weakening of the air flow. At this time, the sealing cover 26 naturally sags under the action of gravity, and cooperates with the retaining ring to close the channel of the air intake pipe 16, thereby preventing the cold air in the cold storage from flowing out through the air intake pipe 16 and causing energy waste. On the contrary, when the heat generation of the box body 1 increases and the negative pressure in the air intake pipe 16 increases, the air flow will push the sealing cover 26 to open, allowing more cold air to enter the physical control room 14 for heat exchange. By automatically adjusting the opening and closing of the air intake pipe 16, the unnecessary loss of cold air in the cold storage is reduced, and the energy utilization efficiency is improved.

[0048] The inclined plate 21 is arranged on the right side of the heat-conducting fin 20 and extends toward the air inlet 17 to form a fan-shaped distribution. When the cold air enters the physical control chamber 14 through the air inlet 17, the inclined plate 21 can guide the airflow to be evenly distributed and further dispersed through the uniform air outlet 19 to ensure that the airflow can fully contact the heat-conducting fin 20 and improve the heat exchange efficiency. The inclined plate 21 and the uniform air outlet 19 allow the cold air to flow through the heat-conducting fin 20 more evenly, improving the uniformity and efficiency of the heat exchange.

[0049] The air outlet dust screen 24 and the air inlet dust screen 18 are respectively installed on the air outlet 23 and the air inlet 17 to prevent dust and impurities from entering the physical control room 14 and the interior of the box 1. The dust screen effectively prevents dust and impurities from contaminating the heat conducting fins 20.

[0050] The sealing ring 8 is installed in the sealing ring groove of the box door groove 7. When the box door 10 is closed, the sealing ring 8 is in close contact with the box door 10 to form a seal. At the same time, the sealing plug 5 is clamped between the threading hole 4 and the wire to prevent external air and moisture from entering the box body 1 through the threading hole 4. The sealing ring 8 and the sealing plug 5 ensure the sealing of the inside of the box body 1 and prevent interference from the external environment. The protection ability of the electrical control component 2 against external factors such as moisture and dust is improved.

[0051] The transparent cover 13 is rotatably mounted in the cover slot 9, and is used to protect the instrument panel 11 and the control buttons 12 from interference from the external environment, while allowing the operator to monitor and operate through the transparent cover 13. The transparent cover 13 enables the operator to clearly see the status of the instrument panel 11 and the control buttons 12, and prevents the instrument panel 11 and the control buttons 12 from being damaged by external factors such as dust and moisture.

[0052] The heat-conducting silicone cloth insulation sheet is bonded between the outer surface of the rear side wall of the box body 1 and the heat-conducting fins 20 to provide electrical insulation and heat conduction functions. The electrical insulation between the box body 1 and the heat-conducting fins 20 is ensured, and safety hazards such as electrical short circuits are prevented. The heat conduction efficiency from the box body 1 to the heat-conducting fins 20 is improved, which is conducive to heat dissipation.

[0053] The insulation layer is coated on the outer surface of the pipe joint 15 and the air inlet pipe 16 to reduce the heat loss of the cold air during the transmission process. The insulation layer effectively reduces the heat loss of the cold air during the transmission process and improves the heat exchange efficiency. By reducing the heat loss, the operating cost of the cold storage is reduced.
