ABSTRACT:
A coil tube bundle for a heat exchanger wherein substantially rigid strips are formed with substantially equally spaced slots inwardly along a front edge thereof with each slot defining a seat opening through a narrower funnel throat, and flexible tubes of resilient circular cross section disposed across aligned rows of said strips and embraced within the seats of the slots to form an interconnected grid of rigid strips and flexible tubes, the grid being coiled to a bundle with the strips parallel to a central axis and the tubes forming spirals with convolutions contacting and spaced apart by edges of the strips opposite the slotted front edges and with the tubes supported at substantially equally intervals throughout their lengths, the plastic material of the tubes and strips being non-brittle at water-freezing temperatures. The strips and tubes are preferably of slippery plastic which is non-brittle at water-freezing temperatures.
