Description
Technical field
The invention belongs to refrigeration technology field, relate in particular to a kind of manufacture method of collecting pipe component and the air-conditioning system of this collecting pipe component of use.
Background technology
The air-conditioning of prior art or other forms of heat pump type refrigeration system, mainly comprise compressor 101, the first heat exchanger 102 and the functional parts such as the second heat exchanger 103, restricting element 104, and the airtight connection of each functional part formed the pipeline connecting parts 105 of medium distribution channel, as shown in Figure 1.Its operation principle is as follows: after the air-conditioning system energising, the low-pressure steam of refrigeration system inner refrigerant is sucked also by compressor 101 and drains into the second heat exchanger 103(condenser behind the boil down to high steam), the outdoor air that sucks of the fan condenser of flowing through simultaneously, take away the heat of cold-producing medium, make high pressure refrigerant vapor be condensed into highly pressurised liquid.Undertaken entering the first heat exchanger 102(evaporimeter after the stream optimization by flow path distributor 106 behind the functional parts such as highly pressurised liquid process filter, restricting element 104), and under corresponding low pressure, evaporating the heat around drawing.Simultaneously fan makes air constantly enter evaporimeter to carry out heat exchange, and the air that turns cold after the heat release is sent to indoor, thereby room air is constantly circulated, reach the purpose that reduces temperature.
Be the operation principle of refrigerating state more than, the stream that heats cold-producing medium under the state is just in time opposite, does not repeat them here.
In above-mentioned refrigerated air-conditioning system, in order to optimize flow passage structure, reach the purpose of sufficient heat exchange, the port of export at the first heat exchanger 102 is connected with collecting pipe component 107 usually.Heating under the state, the port of export of the second heat exchanger 101 also can connect collecting pipe component, and for convenience of explanation, below being refrigerating state is that example is described.
Fig. 2 is a kind of typical collecting pipe component of prior art, and the general copper materials that adopt are made more.By the main discharge 1 of copper material machine-shaping ' as the body junction member, main discharge 1 ' the tube wall welding some equally by the gas-collecting branch pipes 2 of copper material machine-shaping ', each gas-collecting branch pipe 2 ' be connected with the port of export of evaporimeter.Main discharge 1 ' an end and the pipeline fitting of air-conditioning system be welded to connect, the relative other end is made encapsulation process.Main discharge 1 ' and each gas-collecting branch pipe 2 ' between, and main discharge 1 ' and pipeline connecting parts between generally adopt the flame brazing method combination.Often there is following technical problem in this collecting pipe component:
Development along with industrial technology, the use that requirement has the business air conditioner of large standard ton ability also continues to increase, air-conditioning system as large standard ton, the pressure of medium circulation system is higher, requires airtight pressure to improve, and is bulky take copper material as main collecting pipe component, the consumption copper material is more, this can be in any more at current copper valency, in the day by day rare situation of copper material resource, is unfavorable for control and the sustainable development of cost.
Because the collecting pipe component weld parts point of technology is many now, heat affecting is larger mutually, the difficult control of air-tightness.Simultaneously gas brazing rear surface is second-rate, need to carry out necessary pickling, can bring larger impact to environment.
In addition, the air-tightness of collecting pipe component is had relatively high expectations, and because the refrigeration plants such as air-conditioning are placed on the place of outdoor or circumstance complication for a long time, also very high to the Corrosion Protection requirement of gas collection assembly.Even consider the cost of copper material, and consider to replace with other relatively inexpensive material, also must take into full account technique, the method for manufacturing, do not occur to leak and corrosion to guarantee product.
Therefore, how to overcome the deficiencies in the prior art, provide a kind of and can reduce manufacturing cost, can guarantee again the air-tightness of product and corrosion-resistant, the collecting pipe component that can eliminate again acid pickling step simultaneously in manufacture process is the technical problem that those skilled in the art need to be resolved hurrily.
