disclosed are methods and apparatuses for overcoming known plating deficiencies in evaporator assemblies in ice making machine . one embodiment joins the vertical and horizontal partitions together at their intersections so that all surfaces are susceptible for increased soldering / brazing by eliminating the “ voids ” by changing the location and design of the “ weep holes ” in the vertical and / or horizontal partitions . this provides more complete capillary path at the joint between the vertical and horizontal partitions and the evaporator pan allowing improved flow via capillary action of solder / brazing alloy during the joining of the assembled vertical and horizontal partition grid to the evaporator pan . another embodiment increases the clearance between the partitions at their intersections to allow the post - joining plating treatment to penetrate and coat all the partition surfaces by widening the intersection slots in the partitions , but including “ stand - off ” features to center the mating partition in the widened intersection slot .
