Problems solved by technology
[0003] At present, the heat dissipation fan installed on the inverter casing is generally used to dissipate heat from the inverter. The heat dissipation efficiency is low and the effect is poor. Part of the heat generated during work will still remain in the casing. It will continue to accumulate, which will easily cause heat damage to internal parts and affect the normal operation of the inverter

The invention belongs to the technical field of inverter accessories, in particular to a single-phase full-bridge SPWM inverter with a rapid heat dissipation mechanism, comprising an outer frame and a cover snapped and installed on the outer frame, and the outer frame is fixedly connected inside There is a supporting plate, and several equidistant water-cooling pipes are fixedly connected to the inside of the outer frame. The water-cooling pipes are U-shaped structures, and the water-cooling pipes are located inside the supporting plate. When the invention works, the cooling liquid flows along the water-cooling The tube circulates outside the parts and exchanges heat with the heat generated by the parts to realize the heat dissipation and cooling of the inverter. During operation, the cooling liquid flowing inside the water-cooling tube, the cooling fins and the cooling fan on the water-cooling tube can cool the inverter. The inverter performs multiple heat dissipation, which improves the heat dissipation effect and efficiency, and can achieve the effect of rapid heat dissipation, so that the inverter can maintain a stable working state. The U-shaped water-cooled tube can also slow down the flow rate of the coolant, which can further improve the heat dissipation effect .
Description
technical field [0001] The invention belongs to the technical field of inverter accessories, in particular to a single-phase full-bridge SPWM inverter with a rapid heat dissipation mechanism. Background technique [0002] The inverter is a converter that converts DC power into constant frequency and constant voltage or frequency and voltage regulation AC power. It is composed of an inverter bridge, control logic and filter circuit. Inverters are widely used in daily life and are widely used in air conditioners, Computers, TVs, etc. Among them, the single-phase full-bridge SPWM inverter is a kind of inverter, which is an inverter that controls the on and off of the power switching device by the switch control signal generated by the sinusoidal pulse width modulation (SPWM). When the inverter is working, the power consumption will generate a lot of heat, which will increase the temperature of the inverter. It is necessary to dissipate heat from the inverter during operation to...
