Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of refrigerator small pipe diameter fin tubular evaparator as shown in Figure 1, including tactic aluminum pipe 1, it is located in aluminium
Aluminum fin-stock 2 and the side plate 3 for being separately positioned on the two ends of aluminum pipe 1 on pipe 1.On the length direction of aluminum fin-stock 2 there are two rows to be used for
Wear the through hole 4 of aluminum pipe 1.
In order to preferably realize the cooperation between aluminum fin-stock 2 and aluminum pipe 1, the diameter phi of through hole 4 is preferably 6.35mm.Setting every
The length direction of aluminum fin-stock 2 is X-direction, and the width of aluminum fin-stock 2 is Y-direction, then corresponds between the diameter phi of through hole 4, through hole 4 mutually
Position distribution is as follows：Centre-to-centre spacing a between adjacent two exhausting hole 4 in X-direction is 22mm, between same row through hole 4 in the Y direction
Vertical centre is 38.1mm, the water along along the width of aluminum fin-stock 2 between the through hole 4 of the same order of adjacent two panels aluminum fin-stock 2 away from b
Flat deviation angle ψ is 70 °.
Further, in order to improve evaporator capacity, aluminum pipe 1 is facilitated to be connected with aluminum fin-stock 2, through hole 4 is flanging bore, institute
The aluminum pipe 1 stated is interference fitted with flanging bore.After aluminum fin-stock 2 is arranged, aluminum pipe 1 is penetrated from the flanging bore of aluminum fin-stock 2, and aluminum pipe 1 can
The external diameter of aluminum pipe 1 is swollen by the swollen head of metal or water swelling, the form of inflatable reaches the external diameter of aluminum pipe 1 and the flanging bore of aluminum fin-stock 2
Interference fit.
In order to increase the flow-disturbing effect of air flow, the fin being located on the same sagittal plane of aluminum pipe 1 is in uniform intervals
Oblique arrangement.Air flow so on vertical direction can blow to more aluminum pipes 1, form more flow-disturbing, enhancing air and aluminium
The heat transfer effect of pipe 1 and aluminum fin-stock 2.
In order to reduce the influence of evaporator running frosting, aluminum fin-stock 2 uses swollen hole skew formula part fin.Aluminum fin-stock
2 be part, and multiple parts constitute a heat-transfer surface side by side, and the aluminum fin-stock 2 of each part is not directly contacted with, and plays destruction frosting border
The effect of layer, so as to reduce the influence of fin surface frosting.The described sagittal plane of same aluminum pipe 1 being arranged on below evaporator
On fin between spacing be more than be arranged on spacing between the fin on the sagittal plane of same aluminum pipe 1 above evaporator.Evaporation
Device can using length fin arrangement, the longer aluminum fin-stock 2 of evaporator routed underneath length, be spaced between each aluminum fin-stock 2 it is larger,
Be conducive to defrost and reduce influence of the frosting to air flow, it is ensured that the normal air flowing of evaporator and heat exchange efficiency.
The refrigerator small pipe diameter fin tubular evaparator being so designed that, uses external diameter specification to substitute original for 6.35mm aluminum pipe 1
The external diameter specification come is that the through hole 4 that aluminum pipe 1 is worn on 8mm aluminum pipe 1, corresponding aluminum fin-stock 2 also makees corresponding change.Relative to conventional
Finned tube evaporator, newly-designed evaporator, using the aluminum pipe 1 and swollen hole skew formula part fin of pipe with small pipe diameter, evaporator
Material cost can reduce by more than 10%, the refrigerant side coefficient of heat transfer improves about 30%, and air wide pre. drop is low by about 20%, can have
Effect enhancing ventilation effect, improves evaporator capacity, refrigerator unit efficiency is effectively lifted, and serves energy-saving effect
Really, with good economic prospect.
