Embodiment 1

[0035] Example 1, see figure 1 , A transformer radiator with inner fins and telescopic outer fins detachably connected, 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. A number of inner fins 3 and inner grooves 23 are provided in the flow channel 21. The inner fin 3 is provided with an inner fin portion chuck 31. The inner fin 3 is inserted into the inner groove 23 and connected to the heat sink 2 through the inner fin portion clamp 31. The inner fin part clamping head 31 is pluggably inse...

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 peripheral 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 weld...

Abstract

The invention relates to a transformer radiator, and discloses a transformer radiator detachably connected with inner fins and telescopic outer fins. The transformer radiator comprises two oil pipes and radiating fins connected between the two oil pipes, wherein flow channels are arranged in the radiating fins; the outer fins and outer clamping grooves are arranged and formed outside the radiating fins; each outer fin comprises at least two radiating plates; the adjacent radiating plates are telescopically connected in a sleeving manner; one of the radiating plates is provided with an outer fin part chuck; the outer fin part chucks are inserted and connected in the outer clamping grooves in a pluggable manner; the inner fins and inner clamping grooves are arranged and formed in the flow channels; the inner fins are provided with inner fin part chucks; and the inner fin part chucks are inserted and connected in the inner clamping grooves in a pluggable manner. The transformer radiator detachably connected with the inner fins and the telescopic outer fins can rapidly radiate heat when transformer oil flows through the radiating fins; a radiating effect is adjustable; and the problem of poor radiating effect of the existing transformer radiator is solved.

Description

Technical field [0001] The invention relates to a transformer radiator, in particular to a transformer radiator detachably connected with an inner fin and a telescopic outer fin, belonging 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 tran...
