Description

Transformer heatsink with detachable attachment of inner and outer fins

technical field

The invention relates to a transformer radiator, in particular to a transformer radiator detachably connected with inner and outer fins, which belongs to the field of transformer accessories.

Background technique

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 the disadvantage of poor heat dissipation effect.

Contents of the invention

The invention provides a detachably connected transformer radiator with inner and outer fins, which can quickly dissipate heat when transformer oil flows through the cooling fins and has an adjustable cooling effect, which solves the problem of poor cooling effect of the existing transformer radiators.

The above technical problems are solved by the following technical solutions: a transformer radiator with detachable connection of inner and outer fins, including two oil pipes and a number of cooling fins connected between the two oil pipes. For the flow channels of the two oil pipes, the heat sink is provided with outer fins and outer card slots, the outer card slots are linear card slots, and the outer fins are provided with outer fin part clamps, The outer fins are removably plugged into the outer card slots and connected with the heat sink through the outer fin part clamps, and the inner fins and the inner card slots are provided in the flow channel , the extension direction of the inner card groove is the same as the distribution direction of the two oil pipes, the inner fin is provided with an inner fin part chuck, and the inner fin can be pulled out through the inner fin part chuck Inserted into the inner card slot and connected with the heat sink, the oil pipe is provided with a circulation pump, the circulation pump includes a pump casing and a pump shaft rotatably connected to the pump casing, the circulation pump Supported in the oil pipe by shock-absorbing blocks. By arranging the outer fins outside the heat sink, the heat dissipation surface area can be increased, and the increase in the heat dissipation surface area can improve the heat dissipation effect. By setting the inner fins in the heat sink, the surface area of the flow channel can be increased, and the increase in the surface area of the flow channel can increase the contact area between the transformer oil and the flow channel, so that the heat can be quickly transferred to the heat sink when the transformer oil flows through the oil channel. Play a role in improving the cooling effect. Installing a circulation pump to circulate the transformer oil can further improve the cooling effect. The circulating pump is supported by a shock-absorbing block, which can prevent the vibration between the heat sink and the circulating pump from being transmitted to each other and from colliding, resulting in damage and poor electrical contact. When assembling the present invention, according to the heat dissipation requirements of the use environment of the present invention, only a corresponding number of inner and outer fins are assembled on the heat sink, and the excessive inner and outer fins are pulled out from the heat sink.

Further passed the anti-twist capability of the pump shaft.
