The outdoor connecting tube of at present domestic air conditioner all adopts copper pipe, and its cost is higher, and generally speaking, the length of air conditioner connecting pipe is about 3-5 rice, uses the cost price of copper pipe to need about 100 yuan to 150 yuan.
China belongs to the country of copper scarcity of resources, and existing air conditioning chamber outer connecting pipe uses copper resource and its cost of production higher in a large number.
So outer connecting pipe road, existing air conditioning chamber has the following disadvantages: cost of production height, a large amount of copper resources of consumption.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing air conditioning chamber outer connecting pipe uses expensive, the high energy consumption of copper pipe, and a kind of aluminium composite connecting pipe of moulding is provided, and cost of production is lower, the outdoor connecting tube of novel plastic aluminum combined air conditioner of stable performance, energy-conserving and environment-protective.
The utility model is achieved through the following technical solutions:
Mould the aluminium composite connecting pipe, the described tube wall of moulding the aluminium composite connecting pipe includes tight successively nested the combining of multi-layer piping layer, described multi-layer piping layer cross section is a ring structure, wherein, the internal layer of described multi-layer piping layer and skin are polymer material layer, also include metal layer between the internal layer of described multi-layer piping layer and the skin.
Be filled with heat-fusing glue layer between described polymer material layer and the metal layer.
The described tube wall of moulding the aluminium composite connecting pipe includes tight successively nested the combining of five layers of pipe layers, from the inside to the outside, the described tube wall of moulding the aluminium composite connecting pipe includes: inner macromolecule material layer, heat-fusing glue layer, metal layer, heat-fusing glue layer and outer polymer material layer.
Described polymer material layer is a kind of polyethylene pipe layer or heat-proof polythene pipeline layer or crosslinked polyethylene pipe layer or polypropylene pipe layer.
Described metal layer is one deck aluminum pipe or Stainless Steel Tube.
To sum up, the beneficial effects of the utility model are:
The aluminium composite connecting pipe of moulding of the present utility model, be to be inside and outside five layers new micro tubing with macromolecular material and metal alloy compositions and hot-fusible high-molecular glue are compound, be to replace the Updated product that connects outside the existing air conditioning chamber with copper pipe, it is by macromolecular material (polyethylene, crosslinked polyethylene, polypropylene etc.)---hot melt adhesive---metallic material (aluminium, stainless steel etc.)---hot melt adhesive---macromolecular material (polyethylene, crosslinked polyethylene, polypropylene etc.) five layers of formation, has the favorable mechanical performance, bending properties, corrosion resistance, aging quality resistance, heat resistance and energy-conserving and environment-protective performance, long service life.Its structural group becomes macromolecular material and metallic material is composited, and the inside and outside wall of pipeline adopts macromolecular material, and inner wall smooth is less scaling.Outer wall has higher uvioresistant and ageing-resistant performance.Macromolecular material has heatproof, anticorrosive, characteristics such as compressive strength is high, long service life.Metallic material has characteristics such as thermal expansion coefficient is little, bearing capacity is strong.The perfect adaptation of inner and outer pipes and metallic material has improved the combination property of pipeline greatly.This novel tube have higher corrosion-resistant, pressure-bearing is high, high temperature resistant, characteristics such as expansion coefficient is low, flexible, long service life, combination property satisfies fully or surpasses the performance requirement of air conditioner industry to outdoor connecting tube.The utility model can be widely used in outer connecting pipe road, air conditioning chamber system field with its energy-conserving and environment-protective, low cost, high performance characteristics.The overall performance of pipeline satisfies fully or surpasses the performance requirement of air conditioner industry to outdoor connecting tube, but cost has only about 25% of copper pipe.
