    摘要: Restrictions on the major dimension of flattened tubes used in heat exchangers employing oval shaped, two piece headers/tank assemblies can be minimized in a construction including a plurality of flattened tubes (14) each having a minor dimension and a major dimension transverse thereto and extending in spaced parallel relation. Fins (16) are in heat exchange relation with the tubes (14) and a pair of spaced, parallel, elongated headers/tank assemblies (10, 12) are provided between which the tubes (14) extend. At least one of the headers/tank assemblies (10, 12) is a multiple piece header/tank assembly including a header piece (20) and a separate tank piece (22). The header piece (20) is elongated and provided with a plurality of slots (28) sized to receive ends of the tubes (14) with the tube major dimensions being generally transverse to the direction of elongation of the header piece (20). The header piece further includes a peripheral flange (24). The tank piece (22) is elongated, concave and has a peripheral flange (44) nested within the peripheral flange (22) of the header piece (20). The two are bonded together to form a unitary tubular structure and the peripheral flange (42) of the tank piece has alternating crests (52) and valleys (50) with the valleys (50) having a width greater than the tube minor dimension and being aligned with the tube ends. As a consequence, a flow to the tubes (14) is not obstructed by the peripheral flange (42) on the tank piece because of the valleys (50) therein.

    摘要: Uncomfortable air temperatures in an air conditioned vehicle immediately following start up of the air conditioning system or when the air conditioning system compressor is being driven at low speeds are avoided in a cooling system including a blower (22) for blowing air into a compartment (10). An air/liquid heat exchanger (30) is located at the outlet (34) of the blower (22) for cooling air received from the blower (22). The system includes a compressor (50), an expansion device (58), a condenser (54) and a liquid/refrigerant evaporator (64) for expanding refrigerant and cooling a liquid coolant which is circulated through a thermal storage device (92) and the heat exchanger (30) by a pump (86). Upon system start up, or when the compressor (50) is being driven at low speed, the coolant is cooled by the thermal storage device (92) to provide a means of cooling air from the blower (22). At all other times, the coolant is cooled by expansion of refrigerant within the evaporator (64) to not only provide a coolant for use in the heat exchanger (30), but a coolant for recharging the thermal storage device (92) as well.
