A tube used in a heat exchanger, wherein a tube body includes a curved end portion, a pair of parallel portions, a pair of inclination portions, and a fixed portion in which a long end part extending from one of the pair of inclination portions is bent to hold therebetween a short end part extending from the other of the pair of inclination portions, and the tube is a pipe member having a flattened shape in cross-section. Poor brazing is reduced by making the inclination angle of at least part of the other inclination portion with respect to the flat plate portion larger than that of the one inclination portion.

Tube and heat exchanger provided with tube

A receiver includes a cylindrical main tank; a cylindrical internal thread component having an internal thread; a cap having a male thread threaded with the internal thread; a sealing attached to the cap; and a filter portion arranged in the cap. The internal thread component is coaxially arranged to an inner circumference face of the tank. The filter portion includes an internal passage extending inside of the cap, and a net that collects a foreign matter contained in refrigerant flowing through the internal passage.

Receiver and receiver-integrated condenser

In a condenser for an air conditioning system, in particular for motor vehicles, comprising a condensing section () and a supercooling section () which is arranged above the condensing section, comprising an approximately tubular modulator () which is divided by a separating wall () into a lower section (), which is connected to the condensing section (), and an upper section (), which is connected to the supercooling section (), comprising an ascending pipe () between the lower and upper sections of the modulator, and comprising a container () for desiccant in the lower section () of the modulator, the modulator () is provided at the upper side with a plug (), it being possible for the separating wall () with the desiccant container to be removed upwards out of the modulator once the plug has been detached from the interchangeable unit.

Condenser for an air conditioner

In a heat exchanger for cooling air, tubes are disposed vertically and header tanks are connected to the ends of the tubes. The lower side header tank is formed with drains, which are depressions, at positions between the tubes so that condensed water, which accumulates on the lower side header tank, drains away through the drains. Each of the drains has substantially a V-shaped cross-section to facilitate drainage of the water.

Heat exchanger for cooling air

An evaporator comprises a pair of upper and lower horizontal header tanks, a group of heat exchange tubes arranged laterally of the evaporator in front and rear two rows and each connected to the upper header tank and the lower header tank respectively, and a vertical partition wall provided inside the upper header tank and extending laterally of the evaporator so as to form sectioned header chambers for causing a refrigerant to flow through each pair of front and rear adjacent heat exchange tubes in directions opposite to each other. An inlet is provided for a liquid-vapor mixture refrigerant in a sectioned rear header chamber, and an outlet is provided for vaporized refrigerant in a sectioned front header chamber. The evaporator is 3 to 30% in channel opening ratio.
