Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, specifically a transformer intelligent heat dissipation device. Background Technology

[0002] As an indispensable key device in the power system, the stable operation of transformers is directly related to the safety and reliability of the power grid. During the operation of transformers, a large amount of heat is generated due to the existence of core loss (iron loss) and winding loss (copper loss). If this heat cannot be dissipated in time, it will cause the internal temperature of the transformer to rise, which will lead to the aging of insulation materials, performance degradation, and may even cause failure or fire.

[0003] Currently, most transformer cooling devices mainly use cooling fans for cooling. The basic principle is to remove the heat inside the transformer by forced air cooling. The cooling fan mainly cools the transformer through air convection. However, the thermal conductivity of air is low, resulting in low heat dissipation efficiency. Under high load or high temperature conditions, the cooling fan is difficult to quickly reduce the internal temperature of the transformer, which can easily lead to local overheating. To address this, we propose an intelligent cooling device for transformers. Utility Model Content

[0004] To address the problems raised in the background art, this utility model provides the following technical solution: an intelligent heat dissipation device for a transformer, comprising a transformer body, a heat-conducting pipe disposed on the transformer body, the heat-conducting pipe being made of a flexible material, the heat-conducting pipe being wound around the transformer body, the heat-conducting pipe being connected to a cooling box, connecting ears disposed on both sides of the transformer body, a fixing frame disposed on the connecting ears, the fixing frame being connected to the cooling box, and heat dissipation fins disposed on both sides of the transformer body.

[0005] Preferably, the heat pipe has a condensing end and an evaporating end, and an insulating section is provided between the condensing end and the evaporating end. Both the condensing end and the evaporating end are connected to the cooling box to form a complete heat dissipation circulation system, realizing efficient heat conduction and release. The insulating section reduces heat loss and improves heat dissipation efficiency.

[0006] Preferably, the heat pipe is filled with a working fluid, which is water, ammonia or acetone. The working fluid achieves rapid heat transfer through a phase change process of evaporation and condensation inside the heat pipe.

[0007] Preferably, thermally conductive silicone is applied between the heat pipe and the transformer body to fill the gap between them, reduce contact thermal resistance, and improve the efficiency of heat transfer from the transformer body to the heat pipe.

[0008] Preferably, the cooling tank is equipped with a circulation pump, which drives the coolant to circulate between the heat pipe and the cooling tank. The circulation pump drives the coolant to circulate, ensuring the efficient operation of the heat dissipation system.

[0009] Preferably, a temperature sensor is installed on the transformer body, and the temperature sensor is electrically connected to the cooling box. Through real-time monitoring by the temperature sensor, intelligent control of the heat dissipation system is realized, ensuring that the transformer operates within the optimal temperature range.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] During operation, the transformer's windings and core generate a significant amount of heat due to electromagnetic losses. The heat pipes, made of a flexible material, are tightly wrapped around the heat-generating parts of the transformer. The working fluid absorbs heat at the evaporation end and evaporates into a gaseous state. Thermally conductive silicone is applied between the heat pipes and the transformer to reduce contact thermal resistance and improve heat transfer efficiency. Under pressure differential, the gaseous working fluid flows through the adiabatic section of the heat pipes to the condensation end, which extends to the cooling tank. Here, the gaseous working fluid releases heat and condenses into a liquid state. A circulating pump drives the coolant to circulate between the heat pipes and the cooling tank, accelerating heat transfer. The heat dissipation fins on both sides of the transformer assist in heat dissipation through natural convection. Temperature sensors monitor the temperature of key parts of the transformer in real time and transmit the data to the control unit. The control unit dynamically adjusts the flow rate of the circulating pump based on the temperature data, enabling rapid heat transfer from inside the transformer to the outside and preventing localized overheating.
