Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
See Fig. 1, the present invention is a kind of low wind resistance type thin evaporator 1, evaporimeter 1 is two folding syllogic, be divided into evaporimeter A1-1, evaporimeter B1-2 and evaporimeter C1-3, evaporimeter A1-1 and described evaporimeter B1-2 is two-row structure, and described evaporimeter C1-3 is single row configuration, and described evaporimeter A1-1 and described evaporimeter B1-2 connects, described evaporimeter C1-3 connects with described evaporimeter B1-2, and described evaporimeter C1-3 is positioned at described evaporimeter B1-2 bottom.In order to avoid two-stage evaporation device faying face between there is gap, prevent from blowing water, faying face between evaporimeter A1-1 and evaporimeter B1-2 is inclined-plane 1-4, and the contact length of inclined-plane 1-4 is between 12-18mm, and the position of two inclined-plane 1-4 is near evaporimeter A1-1 and evaporimeter B1-2 upper inner.Because two inclined-plane 1-4 contacts area are large, two evaporimeters mutually against, and formed and closely fit, thus ensure that the connection of closed seamless gap, prevent and blow water phenomenon.Faying face between evaporimeter B1-2 and evaporimeter C1-3 is cascaded surface 1-5, and both fit tightly together.Cascaded surface 1-5 can be referred to as zigzag overlapping mode, achieves seamless link, makes wind field even, under condensate level slip-stream.The angle that evaporimeter A1-1 and evaporimeter B1-2 phase folding position are put is 44 °, and the angle that evaporimeter B1-2 and evaporimeter C1-3 phase folding position are put is 158 °.Such angle, in addition single double combining structure, evaporimeter 1 entirety can be made to take up space little, and the correspondence position relation of three sections of evaporimeters A, B, C and axial-flow fan 6 is more reasonable, and the distribution of wind field is more reasonable effectively, improves heat transfer effect.
See Fig. 2, evaporimeter 1 pattern adopts two folding three stage structures to achieve ultrathin design, and evaporimeter C1-3 is 2 single u-shaped pipes, and evaporimeter B1-2 has 7 single u-shaped pipes, and evaporimeter A1-1 is 6 single u-shaped pipes.
The refrigerant flow path of evaporimeter 1 is two enter scene 2, two enter for enterprising and under enter, enterprising stream is: upper inlet pipe 3-1 is located at the outer row of evaporimeter A1-1, cold-producing medium first flows through outer row's U-tube 3 of evaporimeter A1-1 from upper inlet pipe 3-1, flow through interior row's U-tube 3 of evaporimeter A1-1 again, to evaporimeter B1-2, arrange U-tube through flowing through across pipe A3-2, in evaporimeter B1-2, the pipe 3-4 that goes out of row flows out; Lower influent stream road is: lower inlet pipe 3-6 is located at the outer row of evaporimeter B1-2, cold-producing medium enters from lower inlet pipe 3-6 and first flows through the inclining tube 3-7 crossing over and arrange inside and outside evaporimeter B1-2 afterwards, through across the U-tube 3 of pipe B3-3 to evaporimeter C1-3 lower end, then along evaporimeter C1-3 flow to from bottom to top go to interior row after evaporimeter B arranges outward under go out pipe 3-5 and flow out.
The present invention is according to wind field distribution, evaporimeter flow path designs adopts single tube phase heat transfer coefficient to instruct the new design concept of stream, and the exchange capability of heat evaluating each stream adopts phase heat transfer coefficient, and the integrated heat transfer coefficient of stream is high, needed for stream, refrigerant flow is larger, and exchange capability of heat is higher.Concerning one-row heat exchanger, its single copper pipe number phase heat transfer coefficient is 5/4, and to dual-row heat exchanger pipe number windward, its phase heat transfer coefficient is 1, and the leeward pipe number of dual-row heat exchanger, its phase heat transfer coefficient is 2/3.Through the experiment of a large amount of refrigerant flow paths, determine 2 road streams thus, and the shunt ratio relation of knockout.
| Evaporator designs example | Single row of tubes number × relative coefficient | Pipe number × relative coefficient windward | Leeward pipe number × relative coefficient | Integrated heat transfer coefficient |
| Upper stream-phase heat transfer coefficient | 4×5/4 | 7×1 | 3×2/3 | 14 |
| Lower stream-phase heat transfer coefficient | 0 | 9×1 | 7×2/3 | 13.7 |
Integrated heat transfer coefficient on the ratio Main Basis of knockout 4 liang shunt caliber in table, integrated heat transfer coefficient is high, and refrigerant flow needed for its stream is just many, and caliber should be bigger.
According to integrated heat transfer coefficient, the enterprising shunt 4-1 of the knockout 4 of evaporimeter is Large Diameter Pipeline, under to enter along separate routes 4-2 be pipe with small pipe diameter, the integrated heat transfer coefficient of the enterprising shunt 4-1 of evaporimeter is 14, and the integrated heat transfer coefficient entering 4-2 along separate routes under evaporimeter is 13.7.Thus the bore entering 4-2 along separate routes under determining is the 0.92-0.98 of enterprising shunt 4-1 bore.Distributor 4 of the present invention makes two-way shunt pressure distribution and is in suitable proportionate relationship, and our experiments show that, the refrigerant temperature that two-way is imported and exported, close to consistent, effectively avoided air-conditioner condensation, blown water problems while meeting combination property.
