Power distribution cabinet closed mutual-transmission type laminated cooling fin component in high-heat area

Abstract

The invention discloses a power distribution cabinet closed mutual-transmission type laminated cooling fin component in a high-heat area and belongs to the electromechanical power distribution cabinetequipment field. The component comprises a power distribution cabinet body. A heat exchange hole is arranged in an upper end of the power distribution cabinet body. The cooling fin component is installed in the heat exchange hole. The cooling fin component comprises a plurality of mutual transmission cooling units which are stacked up and down. Each mutual transmission cooling unit comprises a wavy cooling fin and a breathing type sealing piece. The two adjacent upper and lower wavy cooling fins are connected in a sealed mode through the breathing type sealing piece. A plurality of uniformlydistributed heat exchange condensation rods are embedded in lower ends of the wavy cooling fins. A condensing agent and a plurality of accelerated heat exchange balls are filled in each mutual transmission cooling unit. Heat in a power distribution cabinet can be transferred to the outside world through a closed stacking mode in a multi-time mutual transmission manner, the lossless condensing agent is used as a medium for heat exchange, the heat is concentrated in the cooling fin component and then is transferred to the outside world, and an internal portion of the power distribution cabinet is kept within a proper temperature range all the time.

Description

technical field [0001] The invention relates to the field of electromechanical power distribution cabinet equipment, more specifically, to a closed and mutual transmission type laminated heat sink assembly for power distribution cabinets in high heat regions. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall prov...

Problems solved by technology

[0004] Under normal circumstances, exhaust fans are installed on the power distribution cabinet to achieve cooling. Fans with axial fans are commonly used, but when the fan is working, external dust, oil and harmful gases will also enter the power distribution cabinet. It is electrostatically adsorbed on the surface of the circuit board, and accumulates over time, which will corrode the components and circuits to a certain extent, and affect its heat dissipation. The accumulated dust will also cause a short circuit in the high-voltage part of the circuit board after being damp.

The longer the working time of the power distribution cabinet, the more prominent the above problems will be. When it accumulates to a certain extent, it will cause a sudden failure of the control part; and the heat exchanger or conventional heat sink has limited heat dissipation performance, and it is difficult to meet the requirements of the power distribution cabinet in high-heat areas. Heat dissipation requirements, as well as the temperature control method of installing the air conditioner in the power distribution cabinet, on the one hand, the installation and operation costs are high and occupy a large internal space, on the other hand, the continuous operation of the air conditioner in a high-heat environment is prone to failure, requiring technical personnel Regular maintenance is difficult to achieve under special circumstances
