Visi Cooler appeared in the 1920s, with a tube-based, compact structure, good heat transfer effect, and used in the food industry. In the early 1930s, Sweden made the first spiral heat exchanger. Then the UK used brazing to produce a plate-fin heat exchanger made of copper and its alloy materials for heat dissipation in aircraft engines. In the late 1930s, Sweden produced the first plate-and-shell heat exchanger for the Ice Cream Showcase. |
