Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer accessories, in particular to a transformer heat dissipation device. Background Art
[0002] A transformer is a device used to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core. The transformer also contains transformer oil for cooling. When the transformer is running, it will inevitably generate heat. The transformer oil near the iron core and the coil will expand when it encounters heat, and circulate up and down through the oil pipe to dissipate the heat. In order to dissipate the heat, a heat sink will also be installed on the transformer to increase the actual heat dissipation area by increasing the contact area with the air. During the long-term use of the heat sink, dust will inevitably accumulate on the surface. When the heat sink is full of dust, the heat dissipation effect of the heat sink will be reduced and it needs to be cleaned. However, the gaps between multiple heat sinks are small and difficult to clean. Utility Model Content
