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. The flow channel 21 is provided with a plurality of inner card slots 23 . The inner slot 23 is a linear slot extending in the vertical direction. Several inner fins 3 are arranged in the flow channel 21 . The inner fin 3 is provided with an inner fin portion clamping head 31 . The in...

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 with fixedly connected telescopic external fins and detachably connected internal fins. The transformer radiator comprises two oil pipes and radiating fins connected between the two oil pipes. A flow channel for communicating the two oil pipes is arranged in each radiating fin. The external fins are arranged at the outside of the radiating fins and each comprises at least two radiating plates. The adjacent radiating plates are telescopically connected with each other in a sleeved manner and only one radiating plate is integrated with the radiating fin. The internal fins and internal clamping grooves are arranged in the flow channel. Each internal fin is provided with an internal fin clamping head. The internal fins are plugged into the internal clamping grooves through the internal fin clamping heads so as to be connected with the radiating fin in a pluggable manner. The transformer radiator with the fixedly connected telescopic external fins and detachably connected internal fins provided by the invention could be used for fast radiating heat with adjustable radiating effects while transformer oil flows through the radiating fin and could solve the problem that the radiating effect of the existing transformer radiator is bad.

Description

technical field [0001] The invention relates to a radiator for transformers, in particular to a radiator for transformers with fixedly connected telescopic outer fins and detachably connected inner fins, 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, 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 o...
