Problems solved by technology
Its disadvantage is that when used in summer, due to the high temperature, the heat dissipation of the transformer is not good, and the transformer will be very hot.
If the temperature of the transformer is too high, it will be unfavorable to the coil of the transformer, which will easily cause the coil to age and shorten the service life of the coil, and if the temperature of the transformer is too high, there will be a fire hazard
At the same time, the built-in coil has certain electromagnetic radiation, which will affect the human body.

Abstract
The invention discloses a heat-dissipating transformer which comprises a shell. A boss is fixed inside the shell, a coil is sleeved on the boss, a cooling device is correspondingly arranged at the upper end of the coil, a plurality of air vents are formed in the shell, a filtering screen is arranged in each air vent, and an anti-radiation layer is coated on the inner wall of the shell. Due to the cooling device arranged at the upper end of the coil and the air vents formed in the shell, temperature of the coil of the transformer can be effectively lowered, heat-dissipating effect is good, and the service life of the transformer is prolonged; in addition, the anti-radiation layer is coated on the inner wall of the shell of the transformer, so that radiation to a human body can be reduced to prevent radiation from harming health of the human body.
Description
technical field [0001] The invention relates to the field of transformers, in particular to a heat dissipation transformer. Background technique [0002] The transformer of existing common notebook computer is made up of transformer housing, built-in coil, input wire, output wire, and its effect is to change alternating current into direct current, and reduces voltage to certain range, supplies power for notebook computer. Its disadvantage is that when used in summer, due to the high temperature, the heat dissipation of the transformer is not good, and the transformer will be very hot. If the temperature of the transformer is too high, it will be unfavorable to the coil of the transformer, which will easily cause the coil to age and shorten the service life of the coil, and if the temperature of the transformer is too high, there will be a fire hazard. At the same time, the built-in coil has certain electromagnetic radiation, which will affect the human body. Contents of ...
