| 摘要 |
The present invention provides a heat-exchanger coil assembly having increased heat conduction area for a given volume by reducing the centre spacing between heat-exchanger coils to a minimum level by avoiding a welding space. The heat-exchanger coil assembly comprises an inlet header (2) at an end section thereof, an inlet tube (3) for introducing a heat-exchanger medium, an outlet header (4) spaced from the inlet header at an end section of an outlet tube (5), and a plurality of heat-exchanger coils (8-1, 8-2, 8-3, 8-4 and 8-5) which are alternately linked to opposite sides of the inlet header (2) and outlet header (4). In another embodiment, the coils are alternately linked to two headers provided from a common inlet or outlet tube. <IMAGE> |
