Description

Technical Field

[0001] This utility model relates to the field of transformer heat dissipation technology, and in particular to a heat dissipation component for the outer casing of a transformer. Background Technology

[0002] Transformers play a vital role in power systems, converting electrical energy from one voltage level to another to meet the needs of different devices. However, transformers generate a significant amount of heat during normal operation, requiring effective heat dissipation to maintain stable operation and extend their lifespan.

[0003] Currently, a common method for transformer cooling is to add radiators to the outer casing in high-temperature areas. These radiators are typically made of aluminum alloy and have a finned structure with gaps between the fins to promote airflow. However, dust and dirt tend to accumulate on the radiator surface and between the fins, which negatively impacts the radiator's cooling performance. Accumulated dust not only increases power consumption but also reduces the radiator's cooling capacity, potentially leading to transformer overheating and unstable operation.

[0004] To address this issue, the existing solution is to periodically use a cloth or spray gun to remove dust between the fins. However, this method significantly increases the manual labor required. Furthermore, the heat generated by the transformer itself is wasted and not effectively utilized.

[0005] Therefore, we need a new type of transformer casing heat dissipation component that can effectively dissipate heat, reduce the accumulation of dust and dirt, and utilize the heat generated by the transformer to improve heat dissipation. This will help improve the operational stability and lifespan of the transformer, while reducing energy consumption and maintenance costs.

[0006] Based on the above background, the present invention proposes an innovative solution for a transformer casing heat dissipation assembly, which aims to solve the problems of dust accumulation and heat utilization in existing transformer heat sinks. Utility Model Content

Simultaneously, the airflow around the heat sinks effectively prevents dust accumulation. Furthermore, utilizing the heat generated by the transformer to improve heat dissipation helps improve the transformer's operational stability and lifespan, while reducing energy consumption and maintenance costs.

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] This utility model provides, for example Figures 1-6 The diagram shows a transformer casing heat dissipation assembly, including a base 1, a support frame 2 fixedly connected to the base 1, and a panel 3 detachably connected to the support frame 2. Several dust-proof heat dissipation devices 4 are evenly installed on the outer side of the panel 3. Each dust-proof heat dissipation device 4 includes a thermoelectric conversion module 41, several heat sinks 42, and a flow-dispersing device 43. One end of the thermoelectric conversion module 41 is fixedly connected to the panel 3, and the other end is connected to the flow-dispersing device 43 via two power transmission lines 44. The heat sinks 42 are fixed in a ring array on the outer side of the thermoelectric conversion module 41, with a cylindrical cavity formed in the center of each heat sink 42. The flow-dispersing device 43 is fixedly installed inside the cylindrical cavity. The thermoelectric conversion module 41 converts the heat generated by the transformer into electrical energy, and the flow-dispersing device 43 accelerates the airflow between the heat sinks 42.

[0030] The working principle is as follows: The thermoelectric conversion module 41 converts the heat energy generated by the transformer into electrical energy, which drives the airflow device 43 to accelerate the airflow speed between the heat sinks 42. Heat dissipation is achieved through energy exchange. The airflow device 43 blows the air around the heat sinks 42, effectively preventing dust from accumulating on the heat sinks 42. At the same time, using the heat generated by the transformer to improve the heat dissipation effect helps to improve the transformer's operational stability and lifespan, while reducing energy consumption and maintenance costs.

[0031] The thermoelectric conversion module 41 has been disclosed in publication number CN208507394U, entitled "A Small Transformer for Easy Heat Dissipation" and publication number CN218848707U, entitled "A Heatsink with Heat Conversion Function". It will not be described again in this application.

[0032] In this embodiment, as Figures 1-3 As shown, the heat sink 42 is fixedly connected to the panel 3. The thermoelectric conversion module 41 is equipped with a protective sleeve, which conducts the heat from the transformer through the heat sink 42 and the panel 3.

[0033] In this embodiment, the heat sink 42 is integrally formed with the panel 3, and the thermoelectric conversion module 41 is installed between the heat sink 42. This improves the conductivity of the heat sink 42 and enhances its heat dissipation effect.

[0034] In this embodiment, the heat sink 42 and the panel 3 are made of cold-rolled steel sheet. Cold-rolled steel sheet has good thermal conductivity and mechanical strength, which can effectively disperse and transfer the heat of the transformer, ensuring the stable operation of the equipment.

[0035] In this embodiment, as Figure 5 As shown, the airflow disturbance device 43 includes a cover plate 431, a motor, and a baffle plate 432. The cover plate 431 is fixed to the heat sink 42 and covers the end of the cylindrical cavity. The motor is fixed to the cover plate 431 and located inside the cylindrical cavity. The baffle plate 432 is fixed to the rotating shaft of the motor. An axial motor can be used to reduce the size of the motor and facilitate installation. The heat from the transformer is converted into electrical energy by the thermoelectric conversion module 41 to power the motor. The motor drives the baffle plate 432 to accelerate the airflow between the heat sink 42, achieving the effects of heat dissipation and reducing dust accumulation, reducing the maintenance of the heat sink 42, and lowering costs.

[0036] In this embodiment, as Figure 5 As shown, the spoiler 432 is spiral-shaped, which facilitates enhanced airflow.

[0037] In this embodiment, as Figures 4-6 As shown, the heat sink 42 has a trapezoidal or rectangular plate structure. Increasing the area of ​​the heat sink 42 improves the heat dissipation effect.

[0038] In this embodiment, the surface of the heat sink 42 is provided with a plurality of protrusions or stripes. This increases the surface area of ​​the heat sink and improves the heat dissipation effect.

[0039] In this embodiment, as Figures 1-3 As shown, the support frame 2 is a cuboid support frame composed of several angle steels. The panel 3 is located on the four vertical faces of the support frame 2, and the upper surface of the transformer is provided with a wiring portion 5 for connecting external lines. This provides support for the panel 3 while also protecting the transformer.

[0040] In this embodiment, as Figure 4 As shown, the turbulence-disrupting device 43 is connected to an external power supply. The external power supply provides a stable turbulence effect, thereby enhancing the heat dissipation effect of the device, while the electrical energy converted by the thermoelectric conversion module 41 serves as a supplement, thereby reducing power consumption and achieving energy saving and improved heat dissipation effect.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
