Abstract

The invention relates to a transformer heat dissipation device. A transformer heat dissipation device to which inner fins and telescopic outer fins are fixedly connected comprises: two oil pipes and a plurality of heat dissipation sheets that are connected between the two oil pipes. A flow channel communicating with the two oil pipes is provided inside each heat dissipation sheet, wherein a plurality of inner fins are provided inside the flow channel, and the inner fins are integrally connected to the heat dissipation sheets. The plurality of outer fins are provided outside each heat dissipation sheet, wherein each outer fin comprises at least two heat dissipation plates, neighboring heat dissipation plates are connected with each other in a sleeved manner telescopically, and only one of the heat dissipation plates is integrally connected to the heat dissipation sheets. The invention provides the transformer heat dissipation device to which the inner fins and the telescopic outer fins are fixedly connected, wherein when transformer oil flows through the heat dissipation sheets, heat can dissipate rapidly, and the heat dissipating effect is adjustable, thereby solving the problem that the heat dissipating effect of existing transformer heat dissipation devices is poor.

Description

technical field [0001] The invention relates to a transformer radiator, in particular to a transformer radiator fixedly connected with inner fins and retractable outer fins, and belongs to the field of transformer accessories. Background technique [0002] When the transformer is running, heat is generated, that is, the load current flows through the transformer winding to generate heat, which must be dissipated in time. The part that dissipates this heat is the transformer radiator. The existing transformer radiator includes two oil pipes and a number of cooling fins connected between the two oil pipes. The cooling fins are provided with flow passages connecting the upper oil pipe and the lower oil pipe. When in use, the transformer oil enters from one oil pipe and is reheated. The heat is dissipated by flowing through the heat sink through the runner, and the finally cooled transformer oil flows back to the transformer through another oil pipe. The existing trans...
