摘要： A double-wall-tube heat exchanger has an outer tube, and an inner tube disposed concentrically in and spaced apart from the outer tube. A clearance between the outer tube and the inner tube and the interior of the inner tube serve as respective refrigerant flow paths. The inner tube has a plurality of interior fins formed on its inner circumferential surface. The interior fins project radially inward; extend in a longitudinal direction of the inner tube; and are arranged at circumferential intervals. The inner tube has a plurality of elongated projections formed on its outer circumferential surface. The elongated projections project radially outward; extend in the longitudinal direction; and are arranged at circumferential intervals. The interior fins are greater in height than the elongated projections. The double-wall-tube heat exchanger exhibits excellent heat exchange performance.

摘要： An evaporator with a cool storage function includes flat refrigerant flow tubes, a cool storage material container disposed in at least one of all air-passing clearances each formed between adjacent refrigerant flow tubes, and an inner fin disposed in the cool storage material container. Each of left and right side walls of the cool storage material container has a contact portion in contact with the inner fin and a noncontact portion not in contact with the inner fin. In an overlap region where the left and right side walls of the cool storage material container overlap with the corresponding refrigerant flow tubes when the container is viewed from the left side or right side thereof, the area of the contact portion of each of the left and right side walls is greater than the area of the noncontact portion of each of the left and right side walls.

摘要： A leeward upper header portion of an evaporator includes first through third sections which communicate with upper ends of heat exchange tubes of first through third tube groups of a leeward tube row. The second tube group, which is an upward flow tube group, and the third tube group, which is a downward flow tube group, form a tube group set. A baffle plate is provided in the second section to be located on the side toward the third section. The baffle plate divides a portion of the interior of the second section into upper and lower spaces and prevents flow of refrigerant toward the upper space. A flow prevention member is provided below the baffle plate so as to prevent flow of refrigerant from the second section into the third section. These two sections communicate with each other in a region above the baffle plate.

摘要： An evaporator including a refrigerant inlet header having a refrigerant inlet at one end thereof, and a plurality of heat exchange tubes arranged at a spacing longitudinally of the inlet header and each having one end joined to the inlet header. The interior of the inlet header is divided by a flow dividing control wall into an upper space for admitting a refrigerant thereinto through the refrigerant inlet and a lower space communicating with the heat exchange tubes. The control wall has a communication hole formed in an end portion thereof opposite to the refrigerant inlet. The upper and lower spaces communicate with each other through the communication hole so that the refrigerant flows through the lower space in a direction opposite to the direction of flow of the refrigerant in the upper space. The evaporator achieves a high heat exchange efficiency.

摘要： An evaporator implemented by a laminated heat exchanger includes a refrigerant inlet header section, a refrigerant outlet header section, and plural inter mediate header sections. A sixth intermediate header section includes a refrigerant channel allowing refrigerant flow in the longitudinal direction thereof and whose downstream end with respect to the refrigerant flow direction is closed, and causes refrigerant to dividedly flow into a plurality of refrigerant flow tube portions. Refrigerant that has flown into the refrigerant inlet header section from a refrigerant inlet flows into the refrigerant outlet header section through the refrigerant flow tube portions and through the intermediate header sections and flows out from a refrigerant outlet. A resistive plate portion within the sixth intermediate header section blocks the refrigerant channel thereof extending in the longitudinal direction thereof. A resistive hole in the resistive plate portion imparts resistance to refrigerant that flows through the refrigerant channel.
