Description

Technical Field

[0001] The utility model relates to the field of transformer design, in particular to an outdoor power supply transformer capable of dissipating heat. Background Art

[0002] A transformer is an electrical device that changes the voltage of alternating current. It consists of two or more coils (called windings) and an iron core. One of the windings, called the "primary winding", is connected to the input power source to receive electrical energy; the other winding, called the "secondary winding", is connected to the load to output electrical energy. Transformers work on the principle of electromagnetic induction. When alternating current passes through the primary winding, the magnetic field generated is conducted to the secondary winding through the iron core. Due to the different ratios of the number of turns of the windings, the voltage in the secondary winding changes accordingly. If the number of turns of the secondary winding is more than the primary winding, the output voltage will increase; if the number of turns of the secondary winding is less than the primary winding, the output voltage will decrease.

[0003] At present, in order to adapt to the harsh outdoor environment, transformers used outdoors are sealed in shells. This installation method will reduce the original heat dissipation performance of the transformer and has the defect of poor heat dissipation performance. When high-power equipment is used outdoors, the heat inside the transformer is very high. If high-power equipment is used for a long time, the transformer is easily damaged and cannot meet the requirements of high-power UL certification. Therefore, it is necessary to add a heat dissipation structure on the basis of the existing transformer to ensure the normal operation of the high-power equipment. At the same time, it is also necessary to ensure that the transformer product is waterproof and anti-electrical, so that it will not be damaged due to water ingress or leakage when used outdoors.
