Embodiment 1

[0035] Example 1, see figure 1 , A transformer radiator fixedly connected with a telescopic outer fin, comprising two oil pipes 1 and a plurality of radiating fins 2 connected between the two oil pipes. The two oil pipes 1 are distributed up and down and extend horizontally. A circulating pump 5 is provided in the upper oil pipe of the oil pipe 1. The circulating pump 5 is suspended in the oil pipe 1 through four shock isolation blocks 9. A number of outer fins 7 are provided outside the heat sink 2.

[0036] See figure 2 , The heat sink 2 is provided with a flow channel 21. Runner 21 connects two oil pipes 1 (see figure 1 ) Connected. The outer fin 7 includes 3 heat dissipation plates. The three heat sinks are distributed into the innermost heat sink 72-3, the middle heat sink 72-2, and the outermost heat sink 72-1. The adjacent heat dissipation plates 72 are telescopically sheathed together. The outermost heat sink 72-1 and the heat sink 1 are connected in an integral st...

Embodiment 2

[0048] The second embodiment is different from the first embodiment:

[0049] See Picture 10 , A circular inner rod 511 is penetrated in the pump shaft 51. The inner rod 511 has a tubular structure. The inner surface of the pump shaft 51 is provided with an inner friction layer 512. The inner rod 511 includes a left rod 5111 and a right rod 5112. The outer peripheral surfaces of the left rod 5111 and the right rod 5112 are both provided with an outer friction layer 5113. The outer friction layer 5113 covers the inner rod 511 along the circumferential direction of the inner rod 511. The left end of the left rod 5111 is connected to the pump shaft 51 through a left energy absorbing spring 513. The right end surface of the left rod 5111 is provided with a plurality of first reversing teeth 5114 distributed along the circumferential direction of the left rod. The right end of the right rod 5112 is connected to the pump shaft 51 through a right energy absorbing spring 514. The ...

Embodiment 3

[0051] The third embodiment is different from the second embodiment:

[0052] See Picture 11 , The heat sink 2 is provided with a number of connecting pipes 22 communicating with the flow channel 21. The oil pipe 1 is provided with a number of oil holes 11. A pipe socket 12 is connected to the outer end of the oil hole 11. The base 12 and the oil pipe 1 are welded together. An inner tube 4 is penetrated in the oil hole 11. The inner end of the inner tube 4 is provided with a flange 41. The inner pipe 4 passes through the pipe socket 12 and then penetrates into the connecting pipe 22 one by one to realize the communication between the oil pipe 1 and the flow passage 21 in the heat sink 2.

[0053] See Picture 12 , The flange 41 is hooked on the inner circumferential surface of the oil pipe 1. The flange 41 and the inner peripheral surface of the oil pipe 1 are connected together only by abutment. The junctions of the socket 12, the inner tube 4 and the connecting tube 22 are...

Abstract

The invention relates to a transformer radiator. A transformer radiator fixedly connected with telescopic external fins comprises two oil pipes and a plurality of cooling fins connected between the two oil pipes, wherein runners communicated with the two oil pipes are arranged in the cooling fins, a plurality of external fins are arranged outside the cooling fins, each external fin comprises at least two cooling plates, adjacent cooling plates are telescopically connected with each other in a sleeved manner, and only one of the cooling plates is integratedly connected with the cooling fin. The invention provides the transformer radiator fixedly connected with telescopic external fins, in which heat can be rapidly dissipated when transformer oil passes through the cooling fins and the heat dissipation effect can be adjusted, and the problem of poor heat dissipation effects of the traditional transformer radiator is solved.

Description

Technical field [0001] The invention relates to a transformer radiator, in particular to a transformer radiator fixedly connected with a telescopic outer fin, 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, and this heat 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 radiating fins connected between the two oil pipes. The radiator is provided with a flow channel connecting the upper oil pipe and the lower oil pipe. When in use, the transformer oil enters and then The transformer oil flows through the heat sink through the runner to dissipate the heat, and finally flows back to the transformer through another oil pipe after the transformer oil is finally cooled. The existing transformer ra...
