Electric heater bracket arrangement

Abstract

A plurality of resistance heater rods are assembled in parallel relationship between the plurality of normally extending brackets and their associated retainers to comprise a subassembly which is then attached as a unit to an evaporator coil. Each of the coils is a continuous element that forms a complete loop with the ends then overlapping such that they are generally centrally located but are located on either side of midpoint such that their movement is not interfered with by other existing structures.

1 . A resistance heater assembly for attachment to an evaporator coil comprising:
 a plurality of elongate brackets arranged in mutual parallel relationship;   a plurality of resistance heater rods aligned in mutual side-by-side parallel relationship and aligned normally with respect to said plurality of brackets, said heater rods being installed against one side of by said brackets; and   a retainer member associated with each of said brackets, said retainer members being attachable to said respective brackets to complete a subassembly which, in turn, is attachable as a unit to the evaporator coil.   
   
   
       2 . A resistance heater assembly as set forth in  claim 1  wherein at least some of said plurality of elongate brackets include on their one side a plurality of scallops for receiving said resistance heater rods. 
   
   
       3 . A resistance heater assembly as set forth in  claim 1  wherein at least some of said retainer members include a plurality of scallops for receiving said resistance heater rods therein. 
   
   
       4 . A resistance heater assembly as set forth in  claim 1  wherein said plurality of resistance heater rods are formed in continuous elements which extend from one end, in a first direction to a return bend, in the opposite direction to an other return bend, and then back in the first direction to the other end, with said one end and other end overlapping on either side of a central position of said rod. 
   
   
       5 . A resistance heater assembly as set forth in  claim 4  wherein said resistance heater rods are bent near their one end and other end such that said one end and other end extend obliquely from the longitudinal direction. 
   
   
       6 . A resistance heater assembly as set forth in  claim 5  wherein said bends are spaced from a bracket disposed therebetween. 
   
   
       7 . A resistance heater assembly for attachment to an evaporator coil comprising:
 a plurality of resistance heater rods aligned in mutual side-by-side parallel relationship with each of said rods being formed in a continuous element which extends from one end, in a first direction to a return bend, in the opposite direction to an other return bend, and then back in the first direction to the other end, with said one end and other end overlapping on either side of a central position on said rods; and   a plurality of brackets for receiving of said heater rods; and   a plurality of retainer members for securing said heater rods to said respective brackets; with the heater assembly then being attached as a unit to the evaporator coil.   
   
   
       8 . A resistance heater assembly as set forth in  claim 7  wherein at least some of said plurality of brackets include on their one side a plurality of scallops for receiving said resistance heater rods. 
   
   
       9 . A resistance heater assembly as set forth in  claim 7  wherein at least some of said retainer members include a plurality of scallops for receiving said resistance heater rods therein. 
   
   
       10 . A resistance heater assembly as set forth in  claim 7  wherein said resistance heater rods are bent near their one end and other end such that said one end and another end extend obliquely from the longitudinal direction. 
   
   
       11 . A resistance heater assembly as set forth in  claim 10  wherein said bends are spaced from a bracket disposed therebetween.
