Embodiment 1

[0035] Embodiment one, see figure 1 , a transformer radiator detachably connected with telescopic outer fins, comprising two oil pipes 1 and a plurality of cooling fins 2 connected between the two oil pipes. The two oil pipes 1 are distributed up and down and extend horizontally. A circulation pump 5 is arranged in the upper oil pipe of the oil pipe 1 . The circulation pump 5 is suspended in the oil pipe 1 through four vibration isolation blocks 9 . A plurality of outer fins 7 are arranged 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 ) connectivity. An outer card slot 24 is also provided on the outside of the heat sink 2 . The outer card slot 24 is a "T" shaped card slot extending in the vertical direction. The outer fins 7 include three cooling plates. The three cooling plates are distributed as the innermost cooling plate 72-3, the middle cooling plate 72-2 an...

Embodiment 2

[0048] Embodiment two, the difference with embodiment one is:

[0049] see Figure 10 , the pump shaft 51 is pierced with a circular inner rod 511 . The inner rod 511 is 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 provided with an outer friction layer 5113 . The outer friction layer 5113 covers the inner rod 511 along the circumference of the inner rod 511 . The left end of the left rod 5111 is connected with the pump shaft 51 through the 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 with the pump shaft 51 through the right energy-absorbing spring 514 . The left end...

Embodiment 3

[0051] Embodiment three, the difference with embodiment two is:

[0052] see Figure 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 several oil holes 11 . The outer end of the oil hole 11 is connected with a pipe seat 12 . The pipe base 12 and the oil pipe 1 are welded together. The inner pipe 4 is pierced in the oil hole 11 . The inner end of the inner tube 4 is provided with a flange 41 . The inner tubes 4 pass through the tube bases 12 and penetrate into the connecting tubes 22 one by one to realize the communication between the oil tube 1 and the flow channel 21 in the cooling fin 2 .

[0053] see Figure 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 only connected together by abutting. The junctions of the pipe base 12 , the inner pipe 4 and the connecting pipe 22 are...

Abstract

The invention relates to a transformer radiator, in particular to a transformer radiator detachably connected with telescopic outer fins. The transformer radiator comprises two oil pipes and a plurality of radiating fins connected between the two oil pipes, wherein a flow channel which is communicated with the two oil pipes is formed in each radiating fin; outer fins and outer clamping grooves are arranged outside the radiating fins; each outer fin comprises at least two radiating plates; adjacent radiating plates are in telescopic sleeve connection; one of the radiating plates is provided with an outer fin part chuck; and the outer fins are spliced in the outer clamping grooves in a pluggable way through the outer fin part chucks, and are connected together with the radiating fins. Through adoption of the transformer radiator detachably connected with the telescopic outer fins provided by the invention, heat can be dissipated rapidly and the heat dissipation effect is adjustable when transformer oil flows through the radiating fins, so that the problem of poor heat dissipation effects in an 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 telescopic outer fins, which 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 transformer radiator has...
