Problems solved by technology
[0006] In order to solve the above technical problems, the present invention provides a circulating ventilation device for power distribution cabinets that avoids heat accumulation, to solve the problem that the existing power distribution cabinets need to install electrical switches and other original components on the back panel, so the vents are opened on the side panels. On the surface, natural wind is blown into the interior of the distribution box to cool it down. Due to the use of natural ventilation for heat dissipation and cooling, some dead corners inside the power distribution cabinet cannot be cooled well, and the natural wind may be affected by the electrical components inside the power distribution cabinet. If it is blocked, it cannot circulate and cool the inside of the power distribution cabinet well. The ventilation and cooling effect is not good, which makes the temperature in the power distribution cabinet rise, which will easily cause the electrical components in the power distribution cabinet to heat and age and affect the use. The practicability is not high. question

The invention discloses a power distribution cabinet circulating ventilation device capable of avoiding heat accumulation, and relates to the technical field of ventilation devices. The problems thatan existing power distribution cabinet adopts natural ventilation, heat dissipation and cooling, so that the temperature in the power distribution cabinet rises, electric appliance elements in the power distribution cabinet are easy to heat and age to influence use, and the practicability is not high are solved. The power distribution cabinet circulating ventilation device capable of avoiding heataccumulation comprises a circulation mechanism; and the circulation mechanism is composed of a synchronous gear, a transmission belt, a circulating gear and a transmission gear. Two cooling fans arearranged in the power distribution cabinet and do up-and-down reciprocating motion through the circulation mechanism in order to enhance the ventilation and heat dissipation effects in the power distribution cabinet, and the rotating directions of two motors are opposite to make the cooling fan well realize convection ventilation, so the ventilation and heat dissipation effects of the device are efficient and thorough, and the practicability of the device is improved.
Description
technical field [0001] The invention belongs to the technical field of ventilation devices, and more specifically relates to a circulating ventilation device for a power distribution cabinet that avoids heat accumulation. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is the general name of 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 provide protection, monitoring and control of the load. [0003] For exampl...
