Description

Technical Field

[0001] The utility model relates to the technical field of transformer cooling, in particular to transformer cooling equipment. Background Art

[0002] The technical field involved in the utility model is that transformer cooling refers to the process of dissipating the heat generated inside the transformer through a heat dissipation device during the operation of the transformer to maintain the normal operating temperature of the transformer. Transformer cooling usually adopts air cooling or oil cooling. Air-cooled transformers usually introduce external air into the transformer through a fan or air duct, and dissipate the heat inside the transformer through convection. This method is simple and low-cost, but has high requirements on the environment and requires air circulation around the transformer. Oil-cooled transformers conduct heat through the insulating oil inside the transformer and dissipate the heat through external oil cooling equipment. This method can effectively dissipate heat and has low requirements on the environment, but it requires regular inspection and maintenance of the insulating oil. In addition to air cooling and oil cooling, there are some special transformer cooling methods, such as water cooling and gas cooling. These methods are all aimed at ensuring that the transformer will not be damaged due to overheating during long-term operation, thereby ensuring the safe operation of the transformer.

[0003] For example, a utility model named "A super-low noise large-capacity air cooler" with publication number CN213815748U comprises a cooler body, a fan box and a transformer-fan assembly, wherein the transformer-fan assembly is provided in plurality; the transformer-fan assembly is composed of a transformer-fan housing and a transformer-fan, a silencer is provided on the outside of the transformer-fan, and the silencer is fixed on the inner wall of the transformer-fan housing; an inner-rib-type cooling pipe is provided in the cooler body, and a spoiler is provided inside the inner-rib-type cooling pipe, and the spoiler is spirally distributed inside the inner-rib-type cooling pipe; an integral fin with a wind grille is provided on the cooler body, and the integral fin is provided on the outside of the inner-rib-type cooling pipe.
