Processing method of heating radiator

Abstract

The invention discloses a processing method of a heating radiator. The processing method comprises the following steps of: (1) processing a plurality of radiating pipe installation holes respectively on two header tubes, and processing thread connector installation holes respectively at the two ends of the two header tubes; (2) processing splicing sections respectively at the two ends of the plurality of radiating pipes, and forming a positioning platform respectively at the transition positions of the splicing sections and radiating pipe bodies; (3) inserting the two ends of the plurality of radiating pipes respectively and sequentially into the radiating pipe installation holes of the two header tubes and then connecting the radiating pipes and the header tubes into a whole in a riveting manner; (4) after the riveting is finished, brazing the header tubes and the radiating pipes into a whole in a weld area formed among the outer hole walls of the radiating pipe installation holes and the radiating pipes, and welding; and (5) after brazing is finished, welding thread connectors in the thread connector installation holes. The processing method has the advantages of small deformation after welding, less processing steps, low energy consumption and low production cost, less environmental pollution, and good production environment; and a radiator prepared by the processing method has long service life and good radiating effect is good.

Description

technical field [0001] The invention relates to a processing method of a heating radiator. Background technique [0002] Existing heating radiators weld the heat dissipation pipe and the header pipe into one body by means of arc welding, that is, first process the heat dissipation pipe installation hole on the header pipe, then insert the heat dissipation pipe into the heat dissipation pipe installation hole, and then use Arc welding fuses the radiator tubes and header tubes together. There are two functions of welding: one is to connect the heat dissipation pipe and the header pipe together, and the other is to seal the heat dissipation pipe and the header pipe. Due to the need to ensure the connection strength and sealing effect between the heat dissipation pipe and the header pipe, the solder layer is thicker, resulting in a large amount of welding, which leads to the disadvantages of large pollution, high energy consumption, poor production environment, and high labor i...

Problems solved by technology

Due to the need to ensure the connection strength and sealing effect between the heat dissipation pipe and the header pipe, the solder layer is thicker, resulting in a large amount of welding, which leads to the disadvantages of large pollution, high energy consumption, poor production environment, and high labor intensity.

Not only that, the temperature during arc welding is very high, and the large amount of welding will cause a large amount of deformation of the heat dissipation pipe and the header pipe. After welding, it needs to be reshaped. Due to the limitation of the operating space, it is difficult to remove the welding slag at the welding place. Reshaping and The two processes of slag cleaning occupy a large proportion in the production cost of radiators, resulting in increased production costs

In addition, since there is no positioning surface on the heat dissipation pipe, the heat dissipation pipe and the header pipe cannot be positioned relative to each other, so it is easy to cause the two header pipes to be non-parallel, and it is difficult to ensure the center distance between the inlet and outlet of the radiator

Also have, existing processing method, its radiating pipe is inserted in the header pipe more, in the course of use, harmful impurity accumulates easily at the junction of the two and accelerates the corrosion of radiator, has a strong impact on the service life of radiator, and radiating pipe More insertions narrow the inner cavity of the header tube, which increases the water resistance of the radiator and results in poor heat dissipation
