<p>PROBLEM TO BE SOLVED: To provide a heat exchange type transformer cooling device having high energy efficiency and high durability against noise and vibration, and excellent cooling performance, and capable of reducing the weight and size.SOLUTION: The heat exchange type transformer cooling device includes an insulating oil circulation pipe configured to form a closed circuit so that the insulating oil filling the interior of a transformer is forwarded again to the transformer after flowing out to the outside, an insulating oil pump formed to transfer the insulating oil, and an insulating oil cooling system formed to cool the insulating oil. The insulating oil cooling system includes a liquid refrigerant maintaining the liquid state in the whole circulation cycle, a refrigerant circulation pipe for circulating the liquid refrigerant, a refrigerant pump formed to transfer the liquid refrigerant, and a heat exchange section for cooling the insulating oil by heat exchange of the liquid refrigerant and insulating oil.</p> |
