Embodiment 1

[0028] Embodiment one, see figure 1, a transformer radiator detachably connected with outer fins and fixedly connected with inner 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 support blocks 9 . A plurality of outer fins 7 are arranged outside the heat sink 2 .

[0029] 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. Several inner fins 3 are arranged in the flow channel 21 . The inner fins 3 are connected together with the cooling fins 2 in an integral structure. The exterior of the heat sink 2 is provided with an outer fin 7 and an outer card slot 24 . The outer card slot 24 is a linear card slot extending in the v...

Embodiment 2

[0037] Embodiment two, the difference with embodiment one is:

[0038] see Figure 7 , 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

[0040] Embodiment three, the difference with embodiment two is:

[0041] see Figure 8 , 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 .

[0042] see Figure 9 , 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 w...

Abstract

The invention relates to a transformer radiator. A transformer radiator with detachably connected outer fins and fixedly connected inner fins comprises two oil pipes and a plurality of cooling fins, wherein the plurality of cooling fins are connected between the two oil pipes; a runner which is communicated with the two oil pipes is arranged in each cooling fin; the outer fins and outer clamping grooves are arranged or formed outside the cooling fins; outer fin part chucks are arranged on the outer fins; the outer fins are inserted into the outer clamping grooves through the outer fin part chucks in a plugging manner and are connected with the cooling fins; a plurality of inner fins are arranged in the runners and are connected with the cooling fins in an integral structure; a circulating pump is arranged in the oil pipe; the circulating pump comprises a pump shell and a pump shaft; the pump shaft is rotationally connected with the pump shell; and the circulating pump is supported in the oil pipe through a shock insulation block. According to the transformer radiator with the detachably connected outer fins and the fixedly connected inner fins, heat can be rapidly dissipated when transformer oil flows through the cooling fins; the heat dissipation effect is adjustable; and the problem of poor heat dissipation effect of 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 outer fins and fixedly connected with 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 oil pipe. The existing t...
