Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer with heat dissipation function. Background Technology

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change alternating current (AC) voltage. A transformer is a static electrical appliance that, through electromagnetic induction between coils, uses the law of electromagnetic induction to convert AC power of one voltage level into AC power of another voltage level at the same frequency.

[0003] Current transformer heat dissipation methods typically involve designing numerous heat dissipation fins on the transformer surface to increase the heat dissipation area. While these fins can increase the heat dissipation area to some extent, the heat generated increases significantly with increasing transformer power and load. When the heat exceeds the heat dissipation capacity of the fins, the heat dissipation effect decreases noticeably. Therefore, to improve the heat dissipation performance of conventional transformers, a transformer with integrated heat dissipation functionality needs to be designed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a transformer with heat dissipation function to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a transformer with heat dissipation function, including a base, a housing, and mounting ears. The housing is fixedly connected to the top of the base. The housing is thin and has an opening design on the front and back. Mounting ears are fixedly connected to both sides of the base, and an iron core winding is installed on the inner side of the outer shell. An input line is fixedly connected to the input end of the iron core winding, and an output line is fixedly connected to the output end of the iron core winding. Thermal pads are fixedly connected to several positions on both sides and the top surface of the outer casing, and heat sinks are fixedly connected to the surface of the thermal pads. The surface of the heat sink is fitted with heat dissipation pipes, which are multi-bent and have several points that pass through the outer casing. Parts of the heat dissipation pipes are attached to the inner side of the outer casing. One end of the heat dissipation pipe is fixedly connected to a heat sink, and the inner side of the heat sink is fixedly connected to several flow channels. A fan is installed at the bottom of the heat sink with the air outlet facing upwards. A water pump is fixedly connected to the output end of the heat sink, and the output end of the water pump is split and connected to the other end of the heat dissipation pipe.

[0007] Preferably, in any of the above solutions, the base is welded to the outer shell, and the outer shell is made of aluminum alloy.

[0008] The above technical solution is adopted as follows: The basic structure of this transformer consists of a base, outer casing, mounting lugs, core windings, input lines, and output lines. The core is the magnetic circuit part of the transformer, composed of core columns and a yoke, and is typically made of stacked silicon steel sheets with a thickness of .mm or .mm to reduce eddy current losses. The windings are the electrical part of the transformer, wound with copper wire wrapped in insulating paper. Concentric windings are used, with the low-voltage winding close to the core and the high-voltage winding wrapped around it.

[0009] This transformer is a small to medium-sized transformer. The input line is connected to the high-voltage input, and the output line is connected to the load.

[0010] This transformer is installed using mounting lugs on the base in conjunction with screws and nuts.

[0011] Preferably, in any of the above solutions, the ear piercing hole installation includes at least two input lines.

[0012] Preferably, of any of the above solutions, at least four output lines are provided, and the thermal pad is made of copper.

[0013] The above technical solution is adopted: This transformer adopts a new heat dissipation structure design, which consists of a thermal pad, heat sink, heat pipe, heat sink, flow channel, fan, and water pump structure.

[0014] By employing a large-area thermal pad in conjunction with a heat sink design, the heat dissipation area of ​​the transformer casing is significantly increased, effectively transferring the transformer's heat to the heat sink. Unlike traditional methods, the heat sink features multiple bent and curved heat dissipation pipes that rapidly remove heat from the transformer casing and heat sink through liquid heat exchange, greatly improving the heat dissipation speed. The multiple bends in the heat dissipation pipes, some distributed inside the casing and penetrating through multiple points, efficiently remove heat from the transformer and its casing through internal and external heat exchange, effectively reducing the transformer's operating temperature. A three-dimensional synergistic heat dissipation system—combining thermal interface materials, heat sinks, and liquid cooling circulation—is employed, constructing a three-level heat dissipation gradient (contact heat conduction → extended heat dissipation → liquid cooling circulation). By building a composite heat transfer network, a breakthrough improvement in transformer thermal management is achieved, with overall heat dissipation performance enhanced by 2-3 orders of magnitude compared to traditional solutions.

[0015] Meanwhile, the liquid that has heated up after heat exchange enters the flow channel of the heat exchanger, and is cooled down by the fan before being pumped back into the heat dissipation tube for reuse.

[0016] Preferably, in any of the above embodiments, the thermal pad is bonded to the outer surface of the housing, and the heat sink is made of copper.

[0017] Preferably, in any of the above embodiments, the surface of the heat sink is provided with a recess that matches the heat dissipation pipe, and the heat dissipation pipe is located above and on both sides of the outer casing.

[0018] Preferably, in any of the above solutions, the heat pipe is bonded or welded to the heat sink and the outer casing, and several fans are arranged side by side.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This transformer with heat dissipation function utilizes a combination of thermal pads, heat sinks, heat pipes, heat exchangers, flow channels, fans, and water pumps. The large-area thermal pads, combined with the heat sink design, significantly increase the heat dissipation area of ​​the transformer casing and effectively transfer heat from the transformer to the heat sinks. Unlike traditional methods, the heat sinks are equipped with multiple bent and curved heat pipes that rapidly remove heat from the transformer casing and heat sinks through liquid heat exchange, greatly increasing the heat dissipation speed. The multiple bends in the heat pipes, some distributed inside the casing and passing through multiple points, efficiently remove heat from the transformer and its casing through internal and external heat exchange, effectively reducing the transformer's operating temperature. A three-dimensional synergistic heat dissipation system—combining thermal interface materials, heat sinks, and liquid cooling circulation—is employed, constructing a three-level heat dissipation gradient (contact heat conduction → extended heat dissipation → liquid cooling circulation). By building a composite heat transfer network, a breakthrough improvement in transformer thermal management is achieved, with its overall heat dissipation performance improved by 2-3 orders of magnitude compared to traditional solutions.

A three-dimensional synergistic heat dissipation system of "thermal conductive interface material + heat sink + liquid cooling circulation" is employed, constructing a three-level heat dissipation gradient (contact heat conduction → extended heat dissipation → liquid cooling circulation). By constructing a composite heat transfer network, a breakthrough improvement in transformer thermal management is achieved, with its overall heat dissipation performance improved by 2-3 orders of magnitude compared to traditional solutions.
