Description
Technical field
The present invention relates to a kind of automobile double concurrent flow D type pipe roof-packed evaporator
Background technology
China Today, the build phase that middle bus and motorbus industry have entered explosion type, future develop is generally good.Simultaneously, terminal client is also more and more higher to the requirement of car load.Obviously, automobiles safe and reliable, beautiful and comfortable, energy-conserving and environment-protective are more favored.
As auto parts and components producer, how to comply with situation, develop the key product of the efficient energy-saving with market competitiveness, seem particularly important.
In the middle of middle bus and motorbus industry, the roof-packed evaporator that uses is the pipe type evaporimeter, now develops the two concurrent flow D type pipe roof-packed evaporators of a kind of 56mm, and is not only superior than pipe type evaporimeter at aspect of performance, and volume is little, and lightweight, cost is low.
Summary of the invention:
The objective of the invention is to be to provide the volume that dwindles roof-packed evaporator under a kind of appearance design prerequisite that can improve middle bus and motorbus interior space and interior trim, weight reduction, reduce refrigerant consumption and resistance, reduce the compressor power consumption, Cost reduction, increase the unit are rate of heat exchange, improve compressor service life and the two parallel flow overhead evaporators that allow assembling more oversimplify.
The present invention adopts following technical scheme to achieve these goals:A kind of automobile double concurrent flow D type pipe roof-packed evaporator, it comprises the first header, the second header, the 3rd header, the 4th header, some flow-stopping sheet, fin, U-shaped pipe, Type B pitch cutting, backplate, inlet tube, the outlets that flat tube, hole size differ.
Described roof-packed evaporator is two concurrent flow D type tubular constructions of two flow processs, D thickness of pipe 56mm wherein, and long L is between 200mm to 1000mm.High H is between 100mm to 500mm.
This roof-packed evaporator inlet tube is above the first header, and outlet is below the 4th header of the same side; This structure need to connect second, third header by U-shaped pipe; And the refrigerant of the flow-stopping sheet of evaporimeter header inside increases by a certain percentage by the flow direction of waist-shaped hole effective area along with refrigerant.
Because the dual parallel flow overhead evaporator of automotive air conditioner that has adopted said structure the present invention is compared with the pipe type evaporator assembly, have following beneficial effect:
1, reduce the refrigerant pressure drop, reduce the refrigerant resistance, and the life-span of greatly having improved compressor
Adopted inlet tube up, outlet below, middle two flow path devices with U-shaped tube transitions can reduce the pressure drop of refrigerant like this and reduce the refrigerant resistance, and be highly advantageous to and reduce compressor and freeze oil in the alluvial storage of evaporimeter inside, guarantee the oil return ratio of compressor, greatly improved the life-span of compressor.
2, the unit are heat exchanger effectiveness is high, and volume is little, and is lightweight, and cost is low
Far above evaporimeters such as other pipe types, therefore identical heat exchange performance lower volume is little, lightweight due to the core body unit are heat exchanger effectiveness of same thickness, and cost is low.
3, internal volume is little, and refrigerant consumption is few, and environmental-protecting performance is excellent
Volume is little, and internal volume is also just little, and refrigerant consumption is also little, and this invention is applicable refrigerant R1234yf of new generation in the future also, and environmental-protecting performance is good!
4, improve the aesthetic property of interior trim, and strengthened the activity spaces such as passenger's step
Because evaporimeter of the present invention is positioned over car body top, the appearance property that has both improved compartment (interior trim that comprises seat etc.) has also strengthened passenger's step inner space, railway carriage or compartment of waiting for bus.
5, self intensity is good, and collecting pipe structure is simple, and production technology is simple, convenient and reliable assembly
The hydroecium main leaf unites two into one, and adopts two D type tubular constructions, to strengthen two parallel flow overhead evaporator core body self intensity, reduces deformation of core and leakage.Collecting pipe structure is simple, and production technology is simple, and leakage rate is low, and the assembly entrucking is convenient and reliable.

The specific embodiment
Be described further below in conjunction with the technical characterictic of drawings and Examples to the present invention's the two parallel flow overhead evaporators of air conditioning for automobiles 56mm.
A kind of dual parallel flow overhead evaporator of automotive air conditioner (referring to Fig. 1～Fig. 5), it comprises:
1-B type partition 2-U type bend pipe 3-backplate 4-flat tube 5-fin 6-holds back sheet (waist-shaped hole) 7-second header 8-the 3rd header 9-the 4th header 10-refrigerant exit pipe 11-refrigerant inlet tube 12-the first header
Described the first header 12 and the 4th header 9 and the second header 7 and the 3rd header 8 two all are fixed together by Type B partition 1, have strengthened the intensity of evaporimeter self.
The refrigerant inlet tube is in the first header 12 upper ends, refrigerant exit Guan Zaidi four header 9 lower ends, U-shaped elbow pipe welding is on the second header 7 and the 3rd header 8, refrigerant flow path is two flow processs, effectively like this reduced pressure drop and be conducive to reduce refrigeration oil in the alluvial storage of evaporimeter inside and reduced the refrigerant resistance, guarantee the oil return ratio of compressor oil, greatly improved the service life of compressor of air conditioner.
The first header 12 is connected by some porous flat pipes with the 4th header 9 with the second header 7 and the 3rd header 8, and porous can effectively raise the heat exchange property of evaporimeter.
The flow-stopping sheet that the first header 12 and the 3rd header 11 some refrigerants of inner insertion differ by the hole effective area, flow-stopping sheet waist-shaped hole size is increasing along with refrigerant flows to, refrigerant is distributed in each flat tube as far as possible evenly, thereby improve the heat exchange property of evaporimeter.
As a kind of conversion of the present embodiment, can adopt stacked or even corrugated tube type, but it is very large to reach in identical performance situation shared volume, cost is certainly also high, installs also inconvenient.
