Description

Technical Field

[0001] The utility model relates to the technical field of intelligent control cabinets, in particular to an intelligent control cabinet for oil and gas wells. Background Art

[0002] The intelligent control cabinet is a closed metal cabinet that integrates a variety of electrical components, instruments, control systems and other equipment. It has the characteristics of intelligence, automation, and high efficiency. It can collect, process and control various electrical signals, thereby improving production efficiency and equipment operation reliability. However, the internal components of the intelligent control cabinet will generate a lot of heat during operation, making its temperature too high, which can easily lead to its failure or scrapping.

[0003] In response to the above problems, a patent document with authorization announcement number CN209001442U discloses a heat dissipation control cabinet, which is provided with a leakage net on the rear door, and the leakage net is covered with a fan cover, and a plurality of fans are provided on the fan cover, and downward-opening shutters are provided on both sides of the rear door to discharge hot air; at the same time, a plurality of long first ventilation holes are provided on the top of the cabinet, which are arranged at right angles on the edges of the cabinet, and the right angles are arranged above and below the shutters, and a plurality of second ventilation holes are provided on the right angles, and the first ventilation holes and the second ventilation holes are used to further expand the dissipation channel of the hot air in the cabinet to reduce the temperature in the cabinet.

[0004] It can be seen that the control cabinet can quickly dissipate the hot air in the cabinet by setting the shutters, the first ventilation holes and the second ventilation holes to ensure the appropriate temperature in the control cabinet. However, the control cabinet has too many openings on the cabinet, and dust in the air can easily enter the cabinet through the openings. Dust accumulates on the components inside the cabinet, which will hinder the dissipation of heat, causing the components to overheat and affect the stable operation of the control cabinet. In addition, overheating of components may also cause short circuits between wires and relays, thereby causing power outages and fire risks. Utility Model Content

[0005] The utility model provides an intelligent control cabinet for oil and gas wells, so as to solve the technical problem in the prior art that too many heat dissipation openings of the control cabinet cause dust to easily enter the cabinet through the heat dissipation openings and accumulate on components, thereby hindering heat dissipation.

[0006] In order to solve the above problems, the oil and gas well intelligent control cabinet provided by the utility model adopts the following technical solutions:

[0011] There are two filters, which are respectively arranged at the air inlet and the air outlet to prevent dust in the external air from entering the cabinet.

[0012] The beneficial effects of the intelligent control cabinet for oil and gas wells provided by the utility model are as follows: 1) by installing a heat spreader around the components, the heat emitted by the components is distributed on the heat spreader, and the heat spreader achieves uniform distribution and efficient heat transfer through the phase change and circulation of the liquid inside the heat spreader, so as to achieve the purpose of heat dissipation and temperature balance for the components, and ensure the heat dissipation effect for the components; 2) the external air enters the cabinet from the air inlet, and the cooling fan promotes the flow of the external air in the cabinet to the air outlet, and takes away the heat emitted by the heat spreader during the flow process, so as to achieve the cooling of the heat spreader and components, and further ensure the heat dissipation of the components; 3) the filter screens arranged at the air inlet and the air outlet can prevent dust in the external air from entering the cabinet, thereby avoiding the accumulation of dust on the components in the cabinet, which affects the heat dissipation of the components. Through the above-mentioned arrangement, the utility model reduces the number of heat dissipation ports opened on the cabinet while ensuring the heat dissipation of the components inside the cabinet, and effectively solves the technical problem in the prior art that the control cabinet has too many heat dissipation ports, which causes dust to easily enter the cabinet from the heat dissipation ports and accumulate on the components, thereby hindering the heat dissipation.
