Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

The invention discloses a heat dissipation mechanism and an electric energy quality treatment device. Cooling air is introduced from an air inlet through a fan, then is guided in the flowing directionthrough an air channel and is exhausted from a first air outlet. Because of the fact that cooling air in the air duct flows through the fins, heat of electronic equipment is firstly transmitted to the radiator; then the air is transmitted to cooling air through fins of the radiator; and finally, the cooling air is exhausted from the first air outlet, so that the electronic equipment is stably andcontinuously cooled. The electronic equipment and the radiator are sealed in the protective shell; and the fins extend out of the outer surface of the protective shell, so that the fins are separatedfrom the electronic equipment, heat dissipation points of the electronic equipment are transferred out of the protective shell, it is ensured that the electronic equipment is always separated from cooling air in the cooling process, and the situation that the electronic equipment makes direct contact with the cooling air and is prone to corrosion damage is avoided.
Description
technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a heat dissipation mechanism and a power quality control device. Background technique [0002] With the rapid development of economy and society, electricity consumption continues to grow at a high level, and the construction of distribution network is relatively lagging behind, which makes the problem of power quality more and more prominent, affecting the quality of electricity consumption of users. Since the low-voltage power grid is a power supply network in which three-phase production and single-phase loads are mixed, the three-phase imbalance of the low-voltage power grid has always been one of the main problems plaguing the power supply unit, resulting in a substantial increase in transformer losses and line losses. [0003] The power quality control device is a device that solves power quality problems such as three-phase imbalance in the power supply ne...
