Description

TECHNICAL FIELD

[0001] The utility model relates to transformer technical field, concretely is self -cooling type special transformer heat radiation subassembly. BACKGROUND

[0002] In the operation of power system, as the key equipment, the stability and reliability of special transformer play a vital role in the normal operation of the whole system. However, a large amount of heat will be generated during the operation of special transformer, if it cannot be cooled in time and effectively, it will lead to the temperature rise of transformer, and further seriously affect its performance and life. The traditional special transformer cooling method mainly relies on natural cooling and fan forced cooling. Natural cooling relies on the heat convection and heat radiation between the surface of transformer and the surrounding air to realize, which is simple but has very low cooling efficiency, especially in the application scene of high load and high efficiency special transformer, it is difficult to meet the cooling demand. The fan forced cooling accelerates the air flow by installing the cooling fan on the surface of transformer, which improves the cooling efficiency, and has certain improvement compared with natural cooling, but still has obvious limitations. In order to improve the above-mentioned disadvantages, the utility model discloses a self-cooling type special transformer heat radiation subassembly with the authorization announcement number CN222354873U, which comprises a self-cooling type special transformer, a self-cooling box is installed at the bottom of the special transformer, and a liquid delivery pipe is installed at the top of the special transformer, which can improve the cooling efficiency of the special transformer during operation to a certain extent.

[0003] However, in actual application, cold water cannot directly contact with the heat dissipation fins, but needs to rely on pipeline to realize heat exchange between the heat dissipation fins. Although the existing technology sets the cooling coil in the gap between the heat dissipation fins, this design still has certain limitations. Specifically, since the contact area between the cooling coil and the heat dissipation fins is limited, and the flow path of the cooling liquid is relatively fixed, the absorption efficiency of the cooling liquid to the heat of the heat dissipation fins is greatly limited. Especially during the operation in the outdoor high-heat three-month summer, the environmental temperature is high itself, and a large amount of heat will be generated during the operation of special transformer. At this time, the traditional cooling method, including the design of setting the cooling coil in the gap of the heat dissipation fins, often cannot meet the cooling demand of the high-load and high-efficiency special transformer. Since the cooling liquid cannot fully absorb the heat on the heat dissipation fins, it is easy to cause the temperature of the transformer to be too high, and further affect the performance and life of the transformer.
