The invention discloses a closed self-circulating heat dissipation power distribution cabinet, which includes a box body, and a plurality of through holes are evenly opened on the upper end surface of the box body, and each of the through holes is sealed and rotatably connected with a heat-conducting material. The heat conduction shell is divided into a symmetrical first liquid storage chamber and a second liquid storage chamber by a heat insulation board. In the present invention, by setting the driving agent, when using the cooling liquid inside the box to absorb the heat inside the box, the driving agent drives the first counterweight to move, thereby driving the heat conduction shell to rotate, and then can continuously transfer the heat in the box to the External exchange heat dissipation not only completes the heat dissipation function inside the box, but also isolates the inside of the box from the outside world to ensure the rainproof and insect-proof function of the box. At the same time, this device uses the heat inside the box as the power to drive the disc to rotate Driven by other electrical equipment, it saves energy, and has fast heat absorption and good heat dissipation effect.
Description
technical field [0001] The invention relates to the technical field of power equipment, in particular to a closed self-circulating heat dissipation power distribution cabinet. Background technique [0002] The power distribution cabinet is a protective shell for arranging power distribution equipment or control circuits. It has a wide range of applications and has different formats depending on the usage. Many of the power distribution cabinets installed outdoors are often designed to prevent rain and insects. It is made of board, and its side wall does not have vents, but the power device in the power distribution cabinet will emit a lot of heat when it is working. If it cannot be discharged in time, the long-term accumulation will affect the service life of the power device, especially during the peak period of power consumption. , The high-speed operation of the power device generates more heat, which may even cause the circuit to catch fire in severe cases. [0003] To ...
