Cooling coil for a thermal storage tower

摘要

A cooling coil arrangement for a cylindrical tower (10) with a plurality of coils (26) arranged in multiply arranged planes with serpentine layouts of each tubing length generally having a vee-shaped layout in each plane between the longitudinal axis of the tower (10) and the tower housing (12), which tubing lengths are provided in each sector (29) of each plane normal to the axis and having a tubing length therein, and the manifolds (48) coupling the tubing lengths to inlet and outlet ports for circulating coolant fluid through the tubing lengths to cool the phase change fluid in the cooling tower (10), and a plurality of the serpentine tubing lengths vertically aligned and preferably arranged with the tubing section of one U-shaped segment of a first tubing length in vertical alignment with the gap of another of the tubing lengths which provides more uniform distribution of the cooling capacity of the cooling fluid and consequently a more uniform development of any crystalline formation of the phase-change fluid on or about each tubing length.
