Accompanying drawing explanation
Fig. 1 is the front view of pipe-coil type evaporator of the present utility model;
Fig. 2 is the right side view of Fig. 1;
Fig. 3 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 to Fig. 3, pipe-coil type evaporator of the present utility model, including first member plate 1, right end plate 2, The radiating fin group 3 that is arranged between first member plate 1 and right end plate 2 and in being located in radiating fin group 3 and carry Pipeline for coolant flowing.
Radiating fin group 3 is in line with the spacing of 1.4mm by multiple radiating fins, each radiating fin by Hydrophilic aluminium foil makes and in venetian blind type structure, and on each radiating fin, the spacing with 17.8mm is opened side by side If 42 major axis are the perforation of horizontal direction ellipse;
First member plate 1 is identical with the structure of right end plate 2 and is symmetricly set on the left and right end of radiating fin group 3, This first member plate 1 and the ellipse offered respectively in right end plate 2 and oval perforation in radiating fin group 3 is corresponding Shape through hole;
Pipeline includes 42 middle 40,38 return bend 41, air inlet pipeline 5 and of long tube One separatory pipeline 6;Wherein,
In the middle of 42 long tube 40 be located in correspondingly in the perforation of radiating fin group 3 and left, It is transversal that right output port passes long tube 40 in the middle of first member plate 1 and the through hole of right end plate 2, every correspondingly Face in the oval aluminum pipe that perforation is adaptive and wall thickness is 0.3mm in described radiating fin group and with heat radiation Perforation in fins set 3 closely cooperates;Major axis dimension is minor axis dimension two times of middle long tube 40;
In 38 return bends 41 21 are connected to the left end of long tube 40 in the middle of adjacent two piece Between Kou, other 17 be connected to position be 2-3,4-5,6-7,8-9,12-13,14-15,16-17, 18-19、22-23、24-25、26-27、28-29、32-33、34-35、36-37、38-39、40-41 Middle long tube 40 right output port between;Return bend 41 uses aluminum pipe to make, return bend 41 transversal Face seamlessly transits for circle and with middle long tube 40;
Air inlet pipeline 5 includes a main air inlet pipe 50 and four point gas being vertically connected in main air inlet pipe 50 Pipe 51, four gas-distributing pipes 51 are the right side of the middle long tube 40 of 1,11,21,31 correspondingly with position Port connects;Air inlet pipeline 5 uses aluminum pipe to make, and the cross section of air inlet pipeline 5 is circular and long with centre Pipe 40 seamlessly transits;
Separatory pipeline 6 include with main 60, upper end being arranged on main separating tube 60 of separating tube point Liquid head 61 and four separatory capillary tubies 62 being connected on liquid-dividing head 61, four separatory capillary tubies 62 are one by one It is that the right output port of the middle long tube 40 of 10,20,30,42 is connected accordingly with position.
In order to the fluid cooling medium in pipeline is carried out flow-disturbing, slow down coolant and flow through speed in pipeline, also have Being beneficial to improve in the middle of heat transfer effect, every and be provided with turbulence structure in long tube 40, this turbulence structure is spoiler Or be female thread.
At this it should be noted that pipeline of the present utility model also can use 21 single u-shaped long tubes and 17 Individual return bend is fabricated to serpentine coil and connects an air inlet pipeline 5 and separatory pipeline 6.
After using pipe-coil type evaporator of the present utility model, when air is along the major axis side of oval middle long tube In time blowing, the trailing vortex loss of formation is little, and the air of flowing closely connects with the periphery of oval middle long tube The area touched increases, and makes the thermal-convection resistance of air side reduce.In oval middle long tube, refrigerant agent flows through During inner surface, the area of contact increases, and disturbance is strengthened.Therefore radiating fin efficiency improves, the significant surface of heat transfer Long-pending increase.Under same hot/cold load, reduce heat transfer temperature difference, thus reduce/raise condensation/vaporization temperature Degree and row/pressure of inspiration(Pi), reduce compression ratio, make the load of compressor alleviate, and total power input reduces, Under conditions of same refrigerating/heating amount, the size making compressor can be with little one grade, vaporizer whole Body size can also suitably reduce, and the adding amount of refrigerant agent can reduce, simultaneously because the reduction of trailing vortex, fall Low aerodynamic noise.Aluminum pipe is used additionally, due to pipeline, can in the case of refrigerating capacity is constant significantly The weight and the cost that alleviate vaporizer itself are low.
Above example is the most for illustration of the utility model, rather than to restriction of the present utility model, relevant skill The technical staff in art field, in the case of without departing from spirit and scope of the present utility model, it is also possible to make Various conversion or modification, the technical scheme of the most all equivalents also should belong to category of the present utility model, should Limited by each claim.
