  • Coil and heat exchanger with the same
    Patent number: 9234711
    Abstract: A coil consists of several arc-shaped tubes whose first end is connected to tail end sequentially to form a continuous curve. The angle spanning between the first end and the tail end of the arc-shaped tube is greater than 180 degrees. The center lines of joints of two adjacent arc-shaped tubes have a common tangent point or the center lines of joints of two adjacent arc-shaped tubes are in tangent connection with a center line of a straight tube. The coil and the heat exchanger with the same have impact construction, small volume and high heat exchange efficiency.
