Description
Technical field
The utility model relates to a kind of three layers of tube-expanding type evaporator fins, more particularly to one kind to be used for refrigerator refrigeration system
It uses.
Background technique
As refrigeration industry is increasingly competitive, major manufacturer is all doing one's utmost to control product cost and and guarantee
Product quality does not decline, so the high efficiency for producing and processing mode all makes the requirement of high standard to the reasonability of product design.
There are two types of the evaporator pipelines that finned evaporator mainly uses at present, and one is copper pipes, and one is aluminum pipe, copper pipes
Higher cost, performance is good, and aluminum pipe is at low cost, and performance is slightly lower and copper pipe.
Three layers of fin drawing expansion type evaporator are since fin is integral fins and is limited by its production technology, and 1. if it is aluminium
Pipe evaporator fin often rolls over the curved argon arc welding of tail using by pipeline (shown in Fig. 1)；2. if it is copper tube and fin evaporator
Copper phosphorus welds after being docked using elbow, then each elbow Fig. 1 can have solder joint at two.Therefore two kinds of processing methods are required to increase
Add welding position, both increases the risk of leakage.
The patent No. 201620882097.8 of State Patent Office's authorization, it is entitled " a kind of three layers of biplate shape evaporator fin "
Its feature includes three layers of evaporation tube, biplate shape fin, support plate and liquid storage device, and three layers of evaporation tube is 8mm by a bore
± 0.01mm, wall thickness are that the aluminum pipe of 0.75mm ± 0.01mm is bent, three layers of evaporation tube, one section of insertion liquid storage device 40mm ±
1mm, the biplate shape fin is big fin and small fin, wherein big fin specification is 153mm※75mm※0.18mm, winglet sheet gauge
Lattice are 117mm※75mm※0.18mm, size 1mm, liquid storage device maximum volume are not 200m1, liquid storage device peace to the liquid storage device wall thickness
Mounted in three layers of evaporation tube entry position, the shortcomings that this structure is the bending of evaporation tube elder generation, then big fin and small fin are put on, this
Kind assembly method complex process is unfavorable for improving assembly efficiency, moreover, two small fins, which have been pressed from both sides, among two big fin has successively arranged
Column, since the assembly hole number processed on the pilot hole and big fin of the processing of winglet on piece is consistent, therefore small fin has one end cannot
It is in contact with evaporation tube road, to reduce refrigeration effect.
Summary of the invention
The task of the utility model is to propose a kind of structure of three layers of tube-expanding type evaporator fin, reduces leakage hidden danger, changes
A kind of higher structure of three layers of tube-expanding type evaporator fin of the thermal efficiency is machined with corresponding and number on long fin and brachypterism plate plane
It measures identical pilot hole and puts at a certain distance, evaporator tube is penetrated from a left side connects long fin and brachypterism piece and pass through tube expansion
After machine swells evaporator tube, long fin and brachypterism piece are closely bonded one, the long finned tube road with evaporator tube
At lower bending to brachypterism piece, bending constitutes three layers of evaporator up and down again after brachypterism piece torsion layer is parallel with long fin pipeline, constitutes three
Load onto end plate and in outlet bending in the both ends of layer evaporator.In the plane of the long fin and brachypterism piece processing there are two with steaming
The hole of device pipe assembly is sent out, and at least there are the spacing of 2-30mm to be arranged successively between long fin and adjacent long fin, and long wing
Piece shares five groups, and at least there are the spacing of 2-30mm to be arranged successively between the brachypterism piece and adjacent brachypterism piece, and brachypterism piece
Share four groups.The long 38-50mm of the long fin, the long 19-25mm of the brachypterism piece.
The utility model is to have the following effects: ensure that the integrality of evaporator pipeline, does not need using argon arc welding welding
Aluminum pipe reduces the slip of product；Make refrigerant in evaporator tube and mobile performance is more preferable, heat exchange efficiency is high, and simplifies
Process reduces welding sequence, has saved welding material, reduces production cost, to improve the competitiveness of product in market.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of evaporator tube installation fin；Fig. 2 is the structural schematic diagram of evaporator tube bending；Fig. 3 is
The forward and backward structural perspective of three layers of evaporator fin；Fig. 4 is the postrotational perspective view of Fig. 3.
Drawing explanation: 1, long fin, 2, evaporator tube, 3, brachypterism piece, 4, end plate.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Embodiment is described in detail in conjunction with the figures above, it is identical that corresponding and quantity is machined on long fin 1 and 3 plane of brachypterism piece
Pilot hole and put at a certain distance, evaporator tube 2 from a left side penetrate by long fin and brachypterism piece connects and by electric tube expander will
After evaporator tube swells, long fin and brachypterism piece are closely bonded one, the long finned tube road vertical folding with evaporator tube
It is curved at brachypterism piece, brachypterism piece turn round layer it is parallel with long fin pipeline after three layers of evaporator of bending composition up and down again, constitute three layers of steaming
Load onto end plate 4 and in outlet bending in the both ends of hair device.
In the plane of the long fin and brachypterism piece process there are two with evaporator tube assembly hole, and long fin with it is adjacent
Long fin between at least there are the spacing of 2-30mm to be arranged successively, and long fin shares five groups, the brachypterism piece and adjacent
Spacing between brachypterism piece at least there are 2-30mm is arranged successively, and brachypterism piece shares four groups.
The long 38-50mm of the long fin, the long 19-50mm of the brachypterism piece.
The evaporation tube road is a complete pipeline, and pipeline centre is not for connecting the welding position on three-layer pipe road.
The technical program, instead of traditional one-piece type fin, eliminates the solder joint between three-layer pipe road by long and short fin,
The leakage rate for reducing product, keeps refrigerant mobile performance in transponder pipe more preferable, improves market competitiveness of enterprises.
The above specific embodiments are only exemplary, is to preferably make skilled artisans appreciate that originally
Patent, be not to be construed as include to this patent range limitation；As long as appointing made by the spirit according to disclosed in this patent
How with change or modification, the range that this patent includes is each fallen within.
