A securing and sealing means is provided to connect the end portions of the conduits and the peripheral and partition walls together and seal the interstices between the surfaces of the end portions and the adjacent surfaces of the peripheral and partition walls. In the method of fabrication the securing and sealing means is provided by dip soldering or brazing within a molten solder bath.
