Refrigeration unit with heat exchanger plates - has recesses in plates with drain holes at lowermost points (SW201276)

摘要

The refrigeration unit is particularly in the form of a deep freezer, having a series of plate-type heat exchangers mounted horizontally one above the other and comprising evaporator plates welded together. The heat exchangers (11) have one or more recesses (13) formed in them, extending from the edge (14), and having a drain hole (12) at the lower most point. The hole can be situated at the intersection of two or more indented lines, preferably running diagonally and dividing the surface of the heat exchanger into several sections inclined towards each other.
