To make full use of the cold heat of LNG, two new style heat exchangers were studied that exchange heat between combustible LNG and air. Channels of each fluid are structurally independent with each other to improve the safety. Heat flow, pressure loss and effectiveness of air coolers for an liquid air enegy storage system were calculated. As for the Parallel Tube heat exchanger, thermal resistance due to the fin depends mainly on the ratio of the fin pitch to the fin thickness. When the ratio was 10, thermal resistance due to the fin was below 20% of total thermal resistance. In the case of the Double Tube heat exchanger, thermal resistance due to the double tube depends mainly on the ratio of the groove pitch to the contact width. When the ratio was 6, thermal resistance due to the double tube was about 20% of total thermal resistance.
