Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to an electric control cabinet with an air drying mechanism. Background Art

[0002] The electric control cabinet is a control cabinet that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment.

[0003] The common electric control cabinet has a relatively simple structure and cannot effectively remove water vapor from the air during ventilation and heat dissipation. It is easy for the internal electrical components to short-circuit due to excessive air humidity, thereby reducing the service life and greatly increasing the maintenance frequency. The practicality is insufficient. Therefore, we propose an electric control cabinet with an air drying mechanism. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings existing in the prior art. The common electric control cabinet has a relatively simple structure and cannot effectively extract water vapor in the air during ventilation and heat dissipation.

[0036] Example 2

[0037] like Figure 1-4As shown, cabinet doors 101 are installed on the front of the cabinet 1 near the installation compartment 2 and the control compartment 3 respectively. The cabinet door 101 is rotatably connected to the cabinet 1 through a rotating shaft. Through the rotation connection between the cabinet door 101 and the cabinet 1, the cabinet door 101 can be quickly opened and closed, which is convenient for maintenance and installation work. A coolant circulation system 301 is provided near the bottom of the control compartment 3, and a controller 302 is provided near the top of the control compartment 3. The fan 405 and the coolant circulation system 301 are electrically connected to the controller 302. The fan 405 and the coolant circulation system 301 can be controlled by the controller 302 to improve the convenience of use. 02 is connected to the slide 201 by sliding, the placement box 203 is fixedly connected to the slider 202, and a calcium chloride desiccant 2031 is provided inside the placement box 203. The calcium chloride desiccant 2031 can keep the inside of the installation chamber 2 dry, thereby improving the service life of the electronic components. The placement box 203 can be quickly removed or installed by sliding the slider 202 and the slide 201, so that the calcium chloride desiccant 2031 that is saturated with moisture absorption can be replaced. The heat exchange coil 401 is fixed to the dehumidification chamber 4 by bolts, and the heat exchange coil 401 is connected to the coolant circulation system 301. The connection of the liquid circulation system 301 can make the cooling liquid circulation system 301 circulate and transport cooling liquid to the inside of the heat exchange coil 401, so that the moisture in the external air condenses when it contacts the heat exchange coil 401, thereby achieving a dehumidification effect. The extraction box 402 and the dehumidification chamber 4 are of a pull-out structure, and the metal mesh 403 is fixedly connected to the extraction box 402. A silica gel desiccant 4021 is provided inside the extraction box 402, and the silica gel desiccant 4021 can further absorb moisture from the condensed air to improve the dehumidification effect. The extraction box 402 and the dehumidification chamber 4 have a pull-out structure, and the extraction box 402 can be quickly disassembled and assembled for easy installation. The silica gel desiccant 4021 that is saturated with moisture absorption is replaced to improve ease of use. A filter is provided inside the vent 404. The fan 405 is fixed to the dehumidification chamber 4 by bolts. The bolt fixation between the fan 405 and the dehumidification chamber 4 can make the fan 405 more secure and improve the stability of use. The installation chamber 2, the air outlet 204, the dehumidification chamber 4, the vent 404 and the air inlet 407 are connected. Under the action of the fan 405, the external air enters the dehumidification chamber 4 through the air inlet 204. After dehumidification, it enters the installation chamber 2 through the vent 404 for heat dissipation and ventilation, and is finally discharged through the air outlet 407.

[0038] The working process of the present utility model is as follows: when dehumidifying the air in the heat dissipation process of an electrical control cabinet with an air drying mechanism, first, driven by the fan 405, the external air enters the dehumidification chamber 4 through the air inlet 407, and the coolant is injected into the heat exchange coil 401 through the coolant circulation system 301. When the air contacts the heat exchange coil 401, the moisture inside it will condense into water droplets and drip into the dehumidification chamber 4, and be discharged through the drain pipe 406 to achieve the dehumidification effect. The air that has undergone the condensation operation passes upward through the extraction box 402. During the process, the silica gel desiccant 4021 will absorb the residual moisture inside it to achieve the purpose of secondary dehumidification. The dehumidified air flows through the vent 404 into the installation chamber 2 for heat dissipation. The calcium chloride desiccant 2031 can continuously ensure that the interior of the installation chamber 2 is dry, and prevent short circuit of components caused by excessive moisture, thereby effectively improving service life and practicality. Finally, the air is discharged from the air outlet 204 to complete the entire working process.
