The heat exchanger incorporates collector and expansion chambers, a primary liquid or gaseous medium, such as water, flowing through its nest of tubes. The tube ends pass through a perforated plate, sealed to the opening of a tank forming the collector chamber. The two chambers are connected via passages through their ends opposite each other.The expansion chamber (50) is formed by a vessel separate from the tank (11) and detachable from it, being typically secured by screws, clips, or spring claws engaging in mating recesses formed in the tank.DEAB- DE3035710 C Heat exchanger comprises a water tank (11) and a separate, enclosed expansion vessel (50), both pref. of plastic, which are detachably fastened together by fastening arrangement located at about half the height of the water tank. Fastenings may be in the form of catches (58), which are elastically flexible, screwed connections or folded connections. Catches may engage in recesses or on projections of the water tank in an interlocking position. Pref. two catches and two projections are provided on opposing sides of the expansion vessel or
