In a brazed condenser for an air conditioner, a collecting tube connected with a collector is prefabricated as a one-piece tube. The collecting tube is connected by tack weld seams with the collector before brazing the collecting tube and the collector together.

A heat exchanger includes a pair of tanks spaced from each other and a plurality of parallel heat transfer tubes fluidly connected between the pair of tanks. Each tube has end portions inserted into holes disposed in the tanks. The end portions of each tube have a maximum diameter which is smaller than a central diameter of a central portion of the tube. At least one of the end portions comprises a straight portion having the maximum diameter and a tapered portion extending from the straight portion with a tapering diameter gradually decreasing from the maximum diameter. Manufacturing this heat exchanger is easier because the tubes are easily inserted into the holes of the tanks. Further, effective brazing between the tubes and the tanks may be achieved by the structure of the tube end portions having the straight portions and the tapered portions even if the length of the tubes vary slightly due to warping or improper manufacture.

A heat exchanger comprising a plurality of oval tubes each having side walls and opposite edges or ends that are thick relative to the thickness of each side wall and with each tube end having a transverse recess extending inwardly of the end between the sides thereof and located in the space between the interior of the tube and an outer edge of the tube and a tube header at each end of the heat exchanger having openings embracing the tubes in the areas between the recesses at each end of the heat exchanger and anchored in the recesses. The disclosure also includes a heat exchanger in which the tank is provided at each end of the heat exchanger enclosing the tube ends at the respective ends and having an edge portion anchored in the recesses.

In a heat exchanger tank, a connecting plate along its longitudinal side edges is provided with flange sections which extend substantially perpendicularly from the connecting plate, the flange sections of the connecting plate each have at least one engagement surface, the legs of a casing at their free end edges are provided with engagement means extending in the longitudinal direction of the casing, the engagement means of the casing lockingly engage the engagement surface of the respective flange section, and sealing connections of the plate with the legs are achieved by brazing.
摘要:
A heat exchanger comprises a fluid box in the form of an elongated vessel having two side walls, two end walls and a base wall, the fluid box being sealingly closed by a welded cover plate on the side opposite to the base wall. The heat exchanger also has at least one bank of tubes which lie mainly outside the fluid box and which communicate sealingly with the interior of the latter through holes formed in the base wall. The side walls of the fluid box extend generally parallel to the plane containing the axes of the tubes of one bank, and include in the vicinity of the cover plate a shoulder which is directed outwardly to serve as a support for welding the cover plate in position. The distance, measured in a transverse direction, between the inner face of each side wall of the fluid box and the axes of the tubes of the bank of tubes closest to it is, at the level of the shoulder smaller than the maximum dimension of the tubes in the same transverse direction. This is achieved mainly by virtue of a hip formed in the side walls, which reduces the overall width of the heat exchanger.
