Description

A kind of condenser of integrated molding fin type aluminium alloy compound material seamless micropore fin and radiator-grid
Technical field
The present invention relates to a kind of condenser and radiator-grid of integrated molding fin type aluminium alloy compound material seamless micropore radiating piece.
Background technology
The condenser of automobile and commercial Civil Air Conditioning System and radiator-grid are made with welding at present and are formed, owing to be in for a long time under the abominable working environment such as vibration, refrigerant very easily leaks, and reclaims very difficulty.According to statistics, the discharge capacity of refrigerant accounts for the over half of refrigerant total release in automobile and the commercial civilian air-conditioning.At present the refrigerant of automobile and commercial civilian air-conditioning mainly uses R134a, though it does not damage the ozone layer, its greenhouse effects index GWP (global warmingpotential) is up to 3100, but also can decomposite the material harmful to health.Therefore, R134a is not a kind of desirable automobile and commercial civilian air conditioner coolant.
Along with the pay attention to day by day of people, replace synthetic working medium (as R134a) to become inexorable trend with natural medium to environmental problem.Because carbon dioxide has good environment friendly (nontoxic, greenhouse effects index is the one thousandth of R134a), security (not flammable), (its refrigerating effect per unit swept volume is 5 times of R22 to refrigerating effect per unit swept volume greatly, under identical refrigeration requires, compare with commercial civilian air-conditioning with the automobile that uses conventional refrigerant, the cold medium flux of carbon dioxide system is less), advantage such as flow resistance is little, more and more be subjected to researchers' attention, be expected to become one of desirable environmental protection refrigerant of 21 century.
In the carbon dioxide refrigeration circulatory system, carbon dioxide is operated in supercriticality (critical pressure PC=7.13MPa), and operating pressure is much higher than traditional refrigerant.And carbon dioxide is in gaseous state all the time in the whole process of refrigerastion, and the condensation liquefaction of general refrigeration system does not take place, and its cooling pressure is the highest can be reached about 11MPa.Therefore, use carbon dioxide, must overcome following two technical barriers as refrigerant: 1, since system works under pressure up to 11MPa, the design of heat transmission equipment, pipeline must be considered the interior conduit requirement of withstand voltage; 2, because gases at high pressure are easy to leak, and the design of heat transmission equipment, pipeline must be considered strict seal request, can not accept the welding procedure manufacturing, should be with the design of sealing silica gel fit sealing, to reach the high pressure sealing safety requirements.
Condenser and radiator-grid are vitals in the air-conditioning system, and whether the design of condenser and radiator-grid rationally has a significant impact refrigeration performance.Under certain evaporating temperature condition, improve condensation effect, reduce condensation temperature, refrigerating capacity will increase, and the input power of compressor reduces, Energy Efficiency Ratio improves.Therefore, condenser and radiator-grid are optimized design, improve its heat transfer efficiency, not only can reduce the pressure at expulsion of compressor, improve the performance of unit, can also reduce the heat exchange area of condenser, save material, reduce cost.At present industrial mass-produced condenser and radiator-grid, the overwhelming majority designs in order to be applicable to the welding procedure production that pressure is lower than 1.0MPa.Because the operating pressure of carbon dioxide system is very high, for the sake of security, common condenser and radiator-grid pipeline need adopt thicker wall thickness usually, have reduced the performance of heat exchanger.The internal diameter of the pipeline heat exchanging performance of condenser and radiator-grid also has very important influence: caliber reduces, and refrigeration matchmaker flow velocity is accelerated, and has strengthened heat convection.On the other hand, if caliber is excessive, in order to bear high pressure, needing increases pipeline wall thickness, and this just causes the increase of condensation vessel volume and weight, and compressor horsepower increases thereupon, wasted the energy.If pressing force container standard design is fit to the condenser and the radiator-grid of high-pressure carbon dioxide, can make that whole condenser and radiator-grid become heavy unusually, volume is big, cost is high.In order to reduce cost, the carbon dioxide system condenser and the radiator-grid of initial exploitation adopt pipe type usually, are about to aluminum pipe and straight aluminium fin and make one by the method for expand tube, and carbon dioxide flows in aluminum pipe.But because the required minor diameter pipeline of this condenser and radiator-grid is long, elbow is many, resistance is big, and the tube expansion technique aspect of narrow tube exists some problems to make that its processing cost is higher, is not widely used.
