Abstract

The invention provides a liquid cooling apparatus based on an oil immersed transformer heat dissipation device. The liquid cooling apparatus comprises a transformer enclosure wall with the back side connected with a back plate through a plurality of connecting members. The connecting members are connected with the back plate and / or the transformer enclosure wall through a flow guide plate arranged at the back surface of the transformer enclosure wall and / or the front surface of the back plate. Cooling agent gaps are formed between the back plate and the transformer enclosure wall through the connecting members. Based on the conventional transformer structure form, the cooling mechanism is directly arranged at the transformer enclosure wall for direct cooling, so that the cooling effect is guaranteed; the transformer enclosure wall is provided with the flow guide plate which is provided with connecting holes, so that the fixing and bearing effect is guaranteed, water flow can be distributed more uniformly, it is guaranteed that no dead space exists in the cooling process, the service life of a transformer is prolonged, the working efficiency of a transformer is guaranteed and the apparatus is worthy of popularization and application.

Description

technical field [0001] The invention relates to the technical field of transformer cooling equipment, in particular to a liquid cooling device based on an oil-immersed transformer radiator. Background technique [0002] With the continuous development of society, people's demand for electricity is also increasing, especially in summer and winter during the peak period of electricity consumption every year, transformers are often overloaded, and most transformers generate a lot of heat due to overloading, which cannot be timely The leakage causes the transformer to stop working or the transformer is damaged, and even causes the transformer to explode, which not only seriously affects the production and life of the people, but also causes damage to the power equipment and causes losses to the country. The reasons are analyzed: [0003] When the transformer is running, the heat generated by the loss of the winding and core must be dissipated in time to avoid insulation damage c...
