Electrical cabinet heat radiation arrangement unit and control method thereof

Abstract

The invention discloses an electrical cabinet heat radiation arrangement unit comprising two adjacent electrical cabinets. Each electrical cabinet is separated into multiple independent power distribution rooms. Each power distribution room is provided with an air inlet and a temperature probe. A heat radiation device is arranged between the two electrical cabinets. The heat radiation device is formed by an air exhausting device arranged in the middle and air exhausting frames arranged at the two sides. The air exhausting device comprises a base, an air cavity and a cover plate. Each air exhausting frame comprises a baseplate, a stand column, a rectangular frame, a counterweight block and an air cover. A gap is reserved between the base and the baseplate. The gaps are reserved between the cover plate, the air exhausting frames and the adjacent electrical cabinets. The temperature probe signals in all the power distribution rooms are inputted to a controller which controls the motor of the fan to work. The beneficial effects of the electrical cabinet heat radiation arrangement unit are that the gap is reserved between the two adjacent electrical cabinets so that the heat radiation area can be increased, the heat radiation device can be used for radiating heat, and the influence of vibration of the fan on the electrical cabinets can be reduced. The invention also discloses an electrical cabinet heat radiation arrangement control method.

Description

technical field [0001] The invention relates to an electric cabinet, in particular to a heat dissipation arrangement unit and a control method of the electric cabinet. Background technique [0002] Electrical cabinets are commonly used electrical equipment, which are used to install electrical components and are usually placed in power distribution rooms. The existing electrical cabinet has the following technical problems: [0003] First, due to the difference in operating current and power, the heat generation of various electrical components is not the same. These electrical components are placed in the same working environment, and the components with large heat generation are easy to affect the components with small heat generation. Therefore, advanced ones The electrical cabinet usually divides the electrical cabinet into multiple spaces, so that the ones with high heat generation are together, and the ones with small heat generation are together to avoid mutual inter...

Problems solved by technology

[0004] Second, when the electrical cabinets are arranged in the power distribution room, they are usually arranged in one or more rows. Two adjacent electrical cabinets are close together, which reduces the area for heat dissipation. In addition, some cabinets have high temperature. Some have a low temperature, and they are easy to interact with each other when they are close together;

[0005] Third, in the existing electrical cabinets, fans are usually installed on the outer wall of the cabinet or on the cabinet door, or on the top. The problem is that it is easy to generate vibration during use. The fan with higher power will vibrate more. Especially after long-term use, the fan will vibrate greatly when dust accumulates inside the fan. Once these tiny vibrations are transmitted to electrical components, it is easy to produce three The problem is that one is that the terminals of the electrical components are easy to go off-line, resulting in failures, and the other is that the internal components of the electrical components, such as resistors and capacitors on the circuit board, are easy to loosen, which affects the service life of the electrical components. Easy to cause misoperation due to vibration
