Abstract
A filter/drier for receiving and discharging a flow of refrigerant having a header with an inlet passage forming a plenum and an outlet passage through the header. A louvered baffle plate has peripheral tabs crimped over an annular flange on the header to form a subassembly. A cup-shaped shell containing desiccant, with a layer of fibrous filter material over the desiccant, is assembled over the header subassembly and sealed to the header by weldment. The peripheral spaces between the crimped baffle tabs provide exclusive flow dispersion to an annular collector space in the header which communicates with the outlet passage.
