Aluminium Condenser Header Pipes

The aluminum condenser header pipe, also known as the aluminum condenser manifold, is an essential component in HVAC systems. Its main function is to evenly distribute the coolant flow path in air coolers, dry coolers, evaporators, and condensers to prevent temperature layers in the pipeline airflow through which the coolant passes.
The aluminum header pipe is made by shaping clad aluminum alloy strips into an open circular tube using a welded tube forming machine. The tube is then prepared through high frequency welding.
The manifold is an oversized pipe that ensures the coolant flows with a small and uniform velocity and pressure. This has a negligible effect on the inlet resistance of the individual circuits. The air conditioner’s fluorine is compressed by the compressor to produce a high-temperature, high-pressure liquefied gas. The gas is then condensed by the condenser and becomes a low-temperature, high-pressure liquid that enters the header pipe.

Frequently Asked Questions

How do Aluminium Condenser Header Pipes compare to copper pipes?

Aluminum condenser header pipes offer several advantages over copper pipes. They are lighter in weight, more cost-effective, exhibit comparable thermal conductivity, and are less susceptible to corrosion.

The causes and solutions of weld leakage of Aluminium Condenser Header Pipe.

Condenser is a kind of equipment that can condense gaseous substances into liquid state, which is widely used in automobile air conditioner and household air conditioner, etc. It is composed of two parts: collector tube and fins. Controlling the leakage rate of aluminum alloy for condenser in line with high-frequency welded tubes to zero has been the goal of all parties, including aluminum strip suppliers, aluminum welded tube producers and condenser manufacturers. However, feedback about condenser manifold leakage continues to come back from the industry. We analyze the causes of condenser manifold leakage from the perspective of condenser manifold producers and propose solutions for your reference in anticipation of further reducing the condenser manifold leakage rate.

Condenser manifold weld leakage pattern.Statistics show that 99.8% of the leakage points of condenser manifolds are concentrated in the weld area, and there are three main manifestations of weld leakage: porosity leakage, micro-crack leakage and slag leakage.

Pore leakage refers to the leakage in the weld area when the test pressure has not yet reached the specified value.

Micro crack leakage. Observation of the microstructure of the condenser collector tube weld can be returned, the crack atmosphere through the two categories of cracks and local micro cracks.

Micro cracks in the weld through the tube wall
Micro crack in the middle of the weld

Inclusion leakage refers to the presence of metal oxides or non-metal oxides, such as Al2O3, SiO2, etc., in the weld seam of the condenser manifold, which are not related to the aluminum alloy organization.

Condenser manifold weld leakage causes.

Longitudinal shearing of aluminum tube strips with irregular cut surfaces.

The guide ring for forming rolls is not designed for the characteristics of aluminum tube strips.

Improper control of welding process parameters.

Solutions to prevent condenser manifold weld leakage

  • Optimization of aluminum strip slitting process
  • Optimizing the design of guide rings for aluminum tube forming rolls
  • Optimization of welding process parameters
  • Optimization of welded pipe adjustment specification

The depth of weld seam of HF welded square header pipe.

The weld seam comprises the fusion line and the heat-affected zone. The depth of the weld seam is related to the skin effect of high-frequency current and the squeezing pressure. The skin effect is dependent on the frequency of the high-frequency welding machine, while the squeezing pressure is dependent on the unit extrusion roll.

Can Aluminium Condenser Header Pipes be used in corrosive environments?

Yes, aluminium condenser header pipes can be used in corrosive environments. The natural oxide layer that forms on the surface of aluminium provides inherent corrosion resistance. However, in highly corrosive environments, it may be necessary to apply additional protective coatings.
