[0002] The vehicle condenser includes flat tubes, fins, support plates and liquid collection pipes, the flat pipes and fins are arranged at intervals, the support plate and the liquid collection pipes, the two ends of the flat pipes are inserted into the liquid collection pipes, and the liquid collection pipes The tube is welded with a pressure plate and a bracket, and there is a gap between the flat tube and the liquid collecting pipe. When the core body composed of the flat tube and the fins is inserted into the liquid collecting pipe and enters the brazing furnace for overall brazing, the liquid collecting pipe is placed on the pressure plate and the bracket. Rotating the liquid collecting pipe under the action of gravity may cause the flat pipe to separate from the liquid collecting pipe, lead to welding failure, increase the size of the core body, change the space position of the pressure plate and the bracket, that is, the installation size changes, and the diagonal angle of the core body changes. There is a large deviation of the line, which seriously affects the quality and appearance of the condenser

Abstract

The invention discloses an anti-rotating condenser welding process. A condenser comprises a core and a liquid collecting pipe, the core comprises flat pipes and fins which are arranged at intervals, a support plate is arranged at the bottom of the core, and two ends of each flat pipe are inserted into the liquid collecting pipe. The welding process includes the steps: firstly, preliminarily fixing two ends of the support plate and the liquid collecting pipe by spot welding; and secondly, placing the spot-welded condenser into a brazing furnace for integral brazing. By the aid of the anti-rotating condenser welding process, the support plate and the liquid collecting pipe are preliminarily fixed by spot welding to form a frame, the core comprising the flat pipes and the fins is stably kept in the frame, the flat pipes are constantly inserted into the liquid collecting pipe when the condenser is placed into the brazing furnace for brazing, welding strength of the flat pipes and the liquid collecting pipe is ensured, uniformity of the diagonal size of the core is effectively controlled, rotation of the liquid collecting pipe is prevented by preliminary spot-welding fixing, mounting sizes of a pressing plate and a support are ensured, and the quality of the condenser is improved.
