<p>An heat exchanger coil is disclosed, particularly but not exclusively for use in domestic apparatus such as dehumidifiers, coolers, and refrigerators. The coil comprises a plurality of turns of tubing (2) in which some are displaced from adjacent turns (2) in a direction substantially perpendicular to the overall axes of the coil. The displacement is defined by one or more spacer rods (10) which extends lengthwise in the coil to hold adjacent turns (2) apart. Typically, the coil is formed from a single length of tubing with the cross-section of the coil being made substantially elongate, and adjacent turns (2) of the coil mutually displaced at both ends of each turn (2).</p> |
