Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, and particularly relates to an energy-saving device for a rectifier control cabinet. Background Art

[0002] All new rectifier control cabinets in the current market are equipped with independent air conditioners, one air conditioner for one cabinet. The purpose of the equipment manufacturer to design the air conditioner is to cool the inside of the control cabinet, but the disadvantages after actual on-site installation are not considered:

[0003] ① Space limitation: The external and internal spaces of the control cabinet are limited. Installing an air conditioner may make the internal space more crowded, affecting the installation or maintenance of other equipment.

[0004] ② Heat dissipation problem: The air conditioner itself generates heat during operation. If the ventilation inside the control cabinet is poor or the heat dissipation conditions are insufficient, the temperature may rise, affecting the performance and lifespan of the equipment inside the control cabinet.

[0005] ③ Humidity management: The air conditioner may also increase the humidity inside the control cabinet while cooling, which may cause corrosion problems, especially more prominent in coastal or humid environments.

[0006] ④ Maintenance difficulty: The maintenance of the air conditioning system may be more complex than that of simple ventilation fans or heat sinks. It requires professional personnel to regularly check and clean the filter, replace the refrigerant, etc.

[0007] ⑤ Cost increase: Compared with traditional heat dissipation solutions, such as fans or heat sinks, the installation and operation costs of the air conditioning system are higher, including purchase costs, energy consumption, and possible maintenance costs.

[0008] Reliability risk: As an additional electronic device, the air conditioner increases the risk points of system failures. If the air conditioning system fails, it may affect the temperature regulation of the entire control cabinet, and further affect the stability and reliability of the control system.

[0009] Based on the above situation, the utility model proposes an energy-saving device for a rectifier control cabinet, which can effectively solve the above problems. Content of the Utility Model

[0010] The purpose of the utility model is to provide an energy-saving device for a rectifier control cabinet. The energy-saving device for the rectifier control cabinet of the utility model has a simple structure and is convenient to use. By setting a central air-conditioning fresh air duct and a hollow cone wind deflector, the original air conditioner is replaced, saving costs and improving space utilization rate.

[0011] The utility model is realized through the following technical solutions:

[0012] An energy-saving device for a rectifier control cabinet, comprising a fresh air duct of a central air conditioner and a rectifier control cabinet. The fresh air duct of the central air conditioner and the rectifier control cabinet are connected through a duct. A hollow cone wind guard is sleeved on the duct located in the fresh air duct of the central air conditioner. The hollow cone wind guard includes a hollow frustum. A conical hole is opened on the hollow frustum. A fan surface is annularly arranged outside the hollow frustum. The conical hole is embedded at the connection of the duct and the fresh air duct of the central air conditioner.

[0013] The purpose of the present utility model is to provide an energy-saving device for a rectifier control cabinet. The energy-saving device for the rectifier control cabinet of the present utility model has a simple structure and is convenient to use. By setting the fresh air duct of the central air conditioner and the hollow cone wind guard, the original air conditioner is replaced, the cost is saved, and the space utilization rate is improved.

[0014] Preferably, a cabinet door is provided on the rectifier control cabinet. An opening is provided on the cabinet door. A stainless steel mesh covering the opening is fixedly provided on the cabinet door.

[0015] Preferably, a non-woven fabric is fixedly provided outside the stainless steel mesh.

[0016] Preferably, the duct includes a first straight pipe, a bent pipe and a second straight pipe connected in sequence. The hollow frustum is sleeved on the first straight pipe.

[0017] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0018] 1. Cost saving: Not installing an air conditioner in the control cabinet can directly reduce the initial investment cost, because the air conditioning system and its installation usually involve significant expenses.

[0019] 2. Simplified maintenance: Removing the air conditioning system can reduce the maintenance work, because the air conditioning equipment itself also requires regular cleaning, maintenance and possible repair.

[0020] 3. Energy consumption reduction: The air conditioning system consumes electricity during operation. Not installing an air conditioner can avoid this part of energy consumption and contribute to energy conservation and emission reduction.

[0021] 4. Space utilization rate improvement: Not installing an air conditioner in the control cabinet can release space, making the control cabinet able to accommodate more equipment and the passageway wider.

[0022] 5. Fault point reduction: The addition of the air conditioning system will bring additional fault points to the control cabinet. Not installing an air conditioner can reduce the risk of system failure.

[0023] 6. Wastewater discharge: Since the rectifier control cabinets are all installed on-site with the equipment, the wastewater generated during the operation of the air conditioner needs to be manually treated. If the wastewater is not treated in time and overflows the container, it will cause potential safety hazards. Description of the Drawings

[0029] Embodiment 1:

[0030] As Figures 1 to 4 shown, the present utility model provides an energy-saving device for a rectifier control cabinet, including a central air-conditioning fresh air duct 1 and a rectifier control cabinet 2. The central air-conditioning fresh air duct 1 and the rectifier control cabinet 2 are connected through a pipeline. A hollow cone wind protector 3 is sleeved on the pipeline located in the central air-conditioning fresh air duct 1. The hollow cone wind protector 3 includes a hollow frustum 31. A conical hole 32 is formed in the hollow frustum 31. A fan surface 33 is annularly arranged outside the hollow frustum 31. The conical hole 32 is embedded at the connection of the pipeline and the central air-conditioning fresh air duct 1.

[0031] Embodiment 2:

[0032] As Figures 1 to 4 shown, the present utility model provides an energy-saving device for a rectifier control cabinet, including a central air-conditioning fresh air duct 1 and a rectifier control cabinet 2. The central air-conditioning fresh air duct 1 and the rectifier control cabinet 2 are connected through a pipeline. A hollow cone wind protector 3 is sleeved on the pipeline located in the central air-conditioning fresh air duct 1. The hollow cone wind protector 3 includes a hollow frustum 31. A conical hole 32 is formed in the hollow frustum 31. A fan surface 33 is annularly arranged outside the hollow frustum 31. The conical hole 32 is embedded at the connection of the pipeline and the central air-conditioning fresh air duct 1.

[0033] Setting up the hollow cone wind protector 3 can prevent wind from leaking out at the connection between the pipeline and the fresh air pipeline 1 of the central air conditioner, and increase the internal wind pressure of the fresh air pipeline 1 of the central air conditioner.

[0036] Furthermore, in another embodiment, a non-woven fabric 43 is fixedly arranged on the outer side of the stainless steel mesh 42.

[0037] Furthermore, in another embodiment, the pipeline includes a first straight pipe 51, a bent pipe 52, and a second straight pipe 53 connected in sequence, and the hollow frustum 31 is sleeved on the first straight pipe 51.

[0038] With the above structure, the greater the turning angle between the first straight pipe 51 and the second straight pipe 53, the smaller the wind resistance, and the greater the air volume at the air outlet in the rectification control cabinet 2.

[0039] The working principle of an embodiment of the present utility model is as follows:

[0040] For an energy-saving device of a rectification control cabinet, the internal wind pressure of the fresh air pipeline of the central air conditioner is greater than the external atmospheric pressure, and the wind will blow into the rectification control cabinet through the pipeline to replace the air conditioner.
