Abstract
The invention relates to a roll-pressing collecting pipe parallel flow evaporator. Collecting pipes on two sides of the existing evaporator are traditional composite aluminum pipes or are assembled and combined after the pipes are punch formed by using double valves. A plurality of positions on the pipe body are welded, air flowing resistance in the pipe body is increased, and refrigerating capacity is lowered. The roll-pressing collecting pipe parallel flow evaporator comprises flow collecting pipes and inlet pipes and outlet pipes arranged on the flow collecting pipes. The evaporator is characterized in that the flow collecting pipes are formed integrally through multi-time punching. A plurality of inner grooves are formed in outer walls of the flow collecting pipes evenly. The collecting pipes on two sides of the evaporator are not the traditional composite aluminum pipes, are not assembled and combined after the pipes are punch formed by using double valves, are integrally formed through multi-time punching and avoid multi-position welding. Due to the fact that the integrated collecting pipes are made of aluminum plates, the wall thickness is smaller than that of original market products. Increased circulating area can reduce inner flowing resistance of the evaporator, and refrigerating capacity is improved.
Description
Technical field
The present invention relates to the parts of the system of air conditioning for automobiles, especially a kind of volume pressure type collector parallel-flow evaporator.
Background technology
The both sides collector of existing evaporimeter assembles synthetic after taking traditional compound aluminum tube or adopting the bivalve punch forming, the many places welding is arranged on body, causes gas flow resistance in body to increase, refrigerating capacity decline.The refrigerant loop of existing Evaporator of Multiunit Parallel Flow is not a single circulation, but a plurality of circuit cycle of process, complex structure, heat transfer effect is poor, and the resistance of refrigerant side and air side is larger.
Summary of the invention
The present invention is directed to above-mentioned defect, a kind of volume pressure type collector parallel-flow evaporator is provided, simple and compact for structure, air-flow is unobstructed, reduces the resistance of refrigerant side and air side, good refrigeration effect.
For this reason, the present invention takes following technical scheme, a kind of volume pressure type collector parallel-flow evaporator, comprise header and be arranged on inlet tube and the outlet on header, it is characterized in that described header adopts that Multi-step forming is one-body molded to be made, and evenly arranges a plurality of inner groovies on the outer wall of described header.
Described header comprises the first header and the 3rd header that is arranged on top, and the second header and the 4th header that are arranged on bottom, walk abreast a plurality of flat tubes are set between described the first header and the second header, walk abreast a plurality of flat tubes are set between described the 3rd header and the 4th header, on described the first header, inlet tube is set, on described the 3rd header, outlet is set.
The cross section of described the first header, the second header, the 3rd header, the 4th header is the D type, the cross section ovalize of described flat tube.
Connect fin on described flat tube outer wall, described fin is ripple type.
A plurality of diaphragm plates are set in described flat tube.
The end of described header arranges boss.
Described header is made by aluminium sheet.
Both sides of the present invention collector does not take traditional compound aluminum tube not adopt assembling after the bivalve punch forming synthetic but adopt Multi-step forming shaping punching press integral type yet, avoids welding the many places welding.Cold-producing medium in collector is biphase gas and liquid flow, take the ring-type flow pattern as leading not, in the collector bottom, is mingled with wave flow.Because the monoblock type collector adopts aluminium sheet, make, thinner than the wall thickness of original market product, increase circulation area used can reduce the interior flow resistance of evaporimeter, improves refrigerating capacity.
The accompanying drawing explanation
The structural representation that Fig. 1 is broken section of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
A kind of volume pressure type collector parallel-flow evaporator as shown in Figure 1, comprise header 1 and be arranged on inlet tube 2 and the outlet 3 on header 1, header 1 adopts one-body molded the making of aluminium sheet Multi-step forming, a plurality of inner groovies 6 evenly are set on the outer wall of header 1, and the end of header 1 arranges boss 7.Header 1 comprises the first header and the 3rd header that is arranged on top, and the second header and the 4th header that are arranged on bottom, walk abreast a plurality of flat tubes 5 are set between the first header and the second header, walk abreast a plurality of flat tubes 5 are set between the 3rd header and the 4th header, arrange on the first header on inlet tube 2, the three headers outlet 3 is set.The cross section of the first header, the second header, the 3rd header, the 4th header is the D type, the cross section ovalize of flat tube 5.Connect fin on flat tube 5 outer walls, fin is ripple type.Flat tube 5 is interior arranges a plurality of diaphragm plates 4.
Cold-producing medium first enters the first header by inlet tube, and then shunting enters elliptical tube, parallel the second header that flows to opposite and the 4th header, the refrigerant volume expansion, flash to gaseous state, absorbs heat, gaseous coolant has flat tube to get back to the 3rd header again, by outlet, is got back in automobile pipeline.Be embedded with fin (fin) between flat tube.The pressure loss that this evaporimeter has air side and refrigerant side is little, heat transfer coefficient is high, lightweight, compact conformation and the characteristics such as filling quantity of refrigerant is few.
Should be understood that these embodiment only are not used in and limit the scope of the invention for the present invention is described.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
