Automobile heat exchanger main fin soldering flux coating production line

Abstract

The invention discloses an automobile heat exchanger main fin soldering flux coating production line and relates to the technical field of automobile heat exchangers. A net band motor is fixed to a bottom frame and is connected with a net band; the two ends of the net band are provided with net band tensioning bases; a spraying box is arranged above the net band; a linear sliding table is arranged above the spraying box; the front side and the rear side of the spraying box are each provided with a heating pipe; a drying motor is arranged above the heating pipes; a soldering flux recycling box is arranged below the spraying box and the net band; a fog exhausting device is arranged on the outer side of the spraying box; a touch screen control box and a soldering flux barrel are further arranged on one side of the spraying box; a stirring motor is arranged in the soldering flux barrel; and a diaphragm pump is further arranged on one side of the soldering flux barrel. According to the automobile heat exchanger main fin soldering flux coating production line, before assembling of a heat exchanger core, soldering flux spraying is firstly performed at the positions, combined with cooling pipes, on heat exchanger main fins, spraying is uniform, the effect is good, time and labor are saved, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of automobile heat exchangers, in particular to a flux coating production line for main pieces of automobile heat exchangers. Background technique [0002] Before the core body of the automobile heat exchanger enters the NB brazing furnace for brazing, the surface of the core body must be sprayed with flux. The role of the flux is to remove the oxides on the surface of the solder and the base metal, protect the weldment and the liquid solder from oxidation during the brazing process, and improve the wettability of the liquid solder to the weldment. [0003] Among them, the flux spraying on the surface of heat dissipation pipes and fins can be completed by a new automatic flux spraying production line, while the position where the heat dissipation pipe and the end of the main sheet are combined is difficult to spray flux evenly due to its concealment and complicated shape. However, the gap between the heat p...

Problems solved by technology

[0003] Among them, the flux spraying on the surface of heat dissipation tubes and fins can be completed by a new type of automatic flux spraying production line, while the position where the heat dissipation pipe and the end of the main piece are combined is difficult to spray evenly due to its concealment and complex shape.

However, the gap between the heat pipe and the end of the main sheet is the most likely place to leak after the heat exchanger core is brazed. If the flux cannot reach this position, it will seriously affect the pass rate of the heat exchanger core.
