Abstract: A heat exchanger manifold for use in heat exchanger used mainly in automobiles is provided. The manifold comprises of two components a header and tank. The header consists of several half cylinders that have ferrule openings and communication port stamped on them. The communication ports are in form of channels that coincide with the ferrule opening. The ferrule openings allow the heat exchanger tubes to slide into the manifold and without any interference. The second component of the manifold comprises a tank. Like the header the tank also consists of several half cylinders, which combined with the header forms several full cylinder. The tank also includes an integral seal along the mating end of the manifold. The manifold also contains a unique inlet/outlet port that allows for ease of assembly of the final heat exchanger.

Abstract: An accumulator with an internal heat exchanger for use in an air conditioning or refrigeration system having a compressor, a condenser, an expansion device, and an evaporator is disclosed. In operation, the accumulator is placed in the system so high pressure, high temperature refrigerant flowing from the condenser and low pressure, low temperature refrigerant flowing from the evaporator simultaneously enter and flow through the heat exchanger disposed in the accumulator whereby the low pressure, low temperature refrigerant absorbs heat and thereby cools the high pressure, high temperature refrigerant. In one embodiment, the heat exchanger comprises a tube having at least one high temperature channel and one low temperature channel extending through the interior of the tube. In a second embodiment, the heat exchanger comprises a single spirally wound coaxial tube having an outer tube and an inner tube positioned within the outer tube.
