Description

Technical Field

[0001] This utility model relates to the field of transformer heat dissipation technology, specifically to a plate-type heat sink for transformers with high-efficiency heat dissipation. Background Technology

[0002] Since its invention in the 19th century, the transformer has undergone numerous technological innovations alongside the booming development of the power industry. Early transformers had small capacities and limited performance, only meeting simple power transmission needs. Today, in ultra-high voltage and extra-high voltage transmission systems, as well as various complex power consumption scenarios, transformers are evolving towards larger capacity, higher voltage levels, miniaturization, and higher energy efficiency. Globally, numerous research teams and companies are continuously investing in research and development to address the ever-increasing power demands and increasingly stringent performance standards.

[0003] With the continuous development of the power industry, the capacity and power of transformers are constantly increasing, and their heat dissipation problem is becoming increasingly prominent. Existing plate transformers are usually equipped with flat plate heat sinks, which have poor heat dissipation performance. Transformers generate a lot of heat during operation. If this heat cannot be dissipated in time, it will cause the transformer temperature to rise, thereby affecting its performance and service life. Utility Model Content

[0004] The purpose of this invention is to provide a plate-type heat sink for transformers with high-efficiency heat dissipation, which solves the problem of poor heat dissipation performance caused by the use of flat plate heat sinks in current plate-type heat sinks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation plate heat sink for transformers, comprising: a connecting mechanism, wherein the connecting mechanism includes two fixed seats, and a first reinforcing rod and a second reinforcing rod are connected between the two fixed seats;

[0006] A heat dissipation mechanism is provided, wherein several heat dissipation mechanisms are provided, and each heat dissipation mechanism is placed between two fixed seats, through which the first reinforcing rod and the second reinforcing rod pass;

[0007] A material guiding mechanism, comprising an oil inlet pipe and an oil outlet pipe, wherein the oil inlet pipe and the oil outlet pipe are respectively located at the upper and lower ends of one side of the connecting mechanism;

[0008] The oil pipe mechanism comprises several oil pipes, which are horizontally inserted horizontally at equal intervals from top to bottom, like a heat dissipation mechanism.

[0009] Preferably, both of the fixed seats have an L-shaped cross-section, with the first reinforcing rod placed on one side of the top of the two fixed seats and the second reinforcing rod placed on the other side of the bottom of the two connecting mechanisms.

[0010] Preferably, each of the heat dissipation mechanisms includes a heat sink with a wavy cross-section. The heat sink has a first fitting hole on one side of its top end for a first reinforcing rod to pass through, and a second fitting hole on the other side of its bottom end for a second reinforcing rod to pass through.

[0011] Preferably, one side of the heat sink is provided with a plurality of first heat pipes and second heat pipes arranged alternately, and both ends of the first heat pipes and the second heat pipes are arranged in a wave shape that fits the outer side of the heat sink, and the length of the first heat pipe is greater than the length of the second heat pipe.

[0012] Preferably, each of the oil pipe mechanisms includes two oil pipes, which are arranged at different heights and are connected to a first connecting pipe at one end. The end of the oil pipe at the higher position away from the first connecting pipe is provided with a second connecting pipe.

[0013] Preferably, the first connecting pipe and the second connecting pipe are inclined in opposite directions and are perpendicular to each other, and both the first connecting pipe and the second connecting pipe are U-shaped.

[0014] Preferably, a support column is provided in the middle of each of the two oil passages, and a propeller blade is provided on the outer edge of the support column, with the outer edge of the propeller blade fitting against the inner edge of the oil passage.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model fixes the heat sink by setting a fixing base, a first reinforcing rod, a second reinforcing rod, a heat sink, a first fitting hole, a second fitting hole, a first heat-conducting pipe, and a second heat-conducting pipe. The first and second reinforcing rods pass through the first and second fitting holes opened on the heat sink respectively to fix the heat sink. The first and second heat-conducting pipes set on the side of the heat sink can increase the heat conduction area. The corrugated heat sink increases the surface area. When the air or cooling medium flows through it, turbulence is formed, which enhances convective heat transfer and makes the heat transfer more efficient.

[0017] 2. This utility model, by setting up an oil passage pipe, a support column and a propeller blade, with the outer edge of the propeller blade attached to the inner edge of the oil passage pipe, forms a spiral oil transport channel inside the oil passage pipe. The transformer oil flows fully in the heat sink, prolonging the residence time of the oil in the heat sink, enhancing the heat exchange between the oil and the heat sink, and improving the heat dissipation effect of the transformer.
