Example Embodiment
[0010] Before the transformation, the original transformer used a radiator and air-cooled cooling method. There are currently 16 high-speed and noisy fans. The transformer no-load loss: 43.00kW, load loss: 154.09kW. The transformer adopts tubular radiator and is air-cooled. The relevant data of the tubular radiator are as follows: the installation center distance of the tubular radiator is 1 880 mm; the number of radiating pipes in each group: 120; the number of groups of the tubular radiator: 8 groups. 16 fans, model BF-4Q4, 250W, 1 450r / min. According to calculation, the effective heat dissipation area of the air-cooled single-tube radiator is 31.00 square meters, and the total effective air-cooled heat dissipation area is: 31.00×8=248.0 square meters. There are 16 fan motors with a rated power of 0.25kW. The purpose of the transformation is to change the tube-type air-cooling to the chip-type natural cooling.
