ABSTRACT:
An evaporator coil heat exchanger assembly of a refrigeration system, such as a transport refrigeration system, which includes an electrical heating element for rapid defrosting of the evaporator coil with its attendant refrigerant carrying tubes and cooling fins. The electrical heating element is quickly attached to the collective edges of the cooling fins by a plurality of low cost spring retainer clips which have one portion which extends between two closely spaced cooling fins to hook a refrigerant carrying tube, and another portion which holds the heating element against edges of the cooling fins with a spring force. The spring retainer clips may be just as quickly removed should the heating element require replacement. Only three curved sections are required to be formed in a single length of wire to form the active elements of the spring retainer clip, and a handle portion is formed in the remaining portion of the single wire length.
