The specific embodiment
(first embodiment)
Fig. 1 is the key diagram of major part of the heat exchanger of first embodiment of the present invention, and Fig. 2 is the key diagram of the heat-transfer pipe of Fig. 1, and Fig. 3 is the key diagram of major part of the plate-shaped fin of Fig. 1.In addition, in order to describe easily the part amplification of accompanying drawing is represented.
In the drawings, Reference numeral 1 is for being provided with the heat-transfer pipe that is formed by flat tube 2 of refrigerant flow path 3, and Reference numeral 10 be with the interval lamination of regulation, installation heat-transfer pipe 1, air mobile plate-shaped fin between it.
The refrigerant flow path 3 that heat-transfer pipe 1 is provided with on a plurality of long axis directions that are provided in the flat tube 2 that is formed by aluminium alloy and extends along longitudinally; On the outer surface of an end of this long axis direction the leading edge portion of heat-transfer pipe 1 (below be called), be provided with the layer (below be also referred to as soldering-tin layer 4) of low-melting scolding tin 4.
This scolding tin 4 is any one compositions in Sn-Cu system, Sn-Bi system, the Sn-Zn system, and its fusing point all is 140～230 ℃, and the thickness of soldering-tin layer 4 is 5～50 μ m.In addition, its scope be arranged on when being inserted into heat-transfer pipe 1 in the groove 11 of plate-shaped fin 10 from groove 11 expose and not with part that plate-shaped fin 10 contacts on (with reference to Fig. 6).Thereby, can reduce the spacing of plate-shaped fin 10, can realize saving spatialization.
What the plate-shaped fin 10 that is formed by aluminium alloy separated regulation on its longitudinally (width) is interval with embedding, fixing a plurality of grooves 11 of heat-transfer pipe 1, and one is provided with the fin flange part 12 to a face lateral buckling in the two edges of groove 11.This groove 11 is the shape with the appearance similar of heat-transfer pipe 1, its width W 1Form degree than big 10～50 μ m of width W of heat-transfer pipe 1.In addition, on the outer surface of plate-shaped fin 10, apply hydrophilic coating film and handle (not shown), the heat resisting temperature of this hydrophilic coating film is about 250 ℃.
Then, describe with reference to the flow chart of Fig. 4 manufacturing approach with regard to the heat exchanger of above-mentioned formation.
The flat tube 2 that becomes heat-transfer pipe 1 is processed or is extruded processing with raw material of aluminum alloy manufacturing growth size through for example drawing; On the outer surface of the leading edge portion of long axis direction, soldering-tin layer 4 is set, be cut to afterwards can with the big or small corresponding size of the heat exchanger that is suitable for.
Plate-shaped fin 10 applies hydrophilic coating film and handles on outer surface after the shape that the raw material punch process with aluminium alloy becomes to stipulate, then through being spaced and a plurality of plate-shaped fins of lamination with regulation such as anchor clamps.At this moment, the groove 11 of the plate-shaped fin 10 of front and back is positioned on the same line.
Then, that kind as shown in Figure 5 embeds assembling heat-transfer pipe 1 respectively in each groove 11 of the plate-shaped fin 10 of the fore-and-aft direction of lamination.The state of this moment is shown in Fig. 6.At this moment; The soldering-tin layer 4 that is located at the leading edge portion of heat-transfer pipe 1 be positioned at from the groove 11 of plate-shaped fin 10 expose and not with plate-shaped fin 10 position contacting; In addition, between the periphery of heat-transfer pipe 1 and groove 11 (fin flange part 12), form small gap g (10～50 μ m/2).
Then, the plate-shaped fin 10 that will in groove 11, embed heat-transfer pipe 1 heating furnace of packing into is with temperature heating 5～10 minute the degree higher 20～30 ℃ than the fusing point (140～230 ℃) of scolding tin 4.At this moment, hope in the heating furnace it is reducing atmosphere or vacuum atmosphere, but under the situation about in air atmosphere, heating, if on heat-transfer pipe 1, apply solder flux in advance, then the wetability of scolding tin becomes good.In addition, it is about 250 ℃ owing to be applied to the heat resisting temperature of the hydrophilic coating film on the outer surface of plate-shaped fin 10, so need set the heating-up temperature of heating furnace lower than 250 ℃.
Heat-treat by heating furnace through above-mentioned that kind, that kind as shown in Figure 7, scolding tin 4 fusions flow among the gap g between heat-transfer pipe 1 and the plate-shaped fin 10 (fin flange part 12) through capillarity.And through cooling off, the scolding tin 4 that heat conductivity is high is filled among the gap g between heat-transfer pipe 1 and the plate-shaped fin 10, and both are fixed into one.
The heat exchanger of this embodiment is provided with low-melting soldering-tin layer 4 in advance on the leading edge portion outer surface of the heat-transfer pipe 1 that the flat tube 2 by the aluminium alloy system with refrigerant flow path 3 forms; 1 group of this heat-transfer pipe is gone in the plate-shaped fin 10 with the aluminium alloy system that supplies heat-transfer pipe 1 to embed fixing groove 11 and apply hydrophilic coating film processing ground lamination in advance; Low temperature with below the heat resisting temperature of hydrophilic coating film heats; The scolding tin 4 of fusion is flow in the gap between plate-shaped fin 10 and the heat-transfer pipe 1 carry out filling; By the high scolding tin of heat conductivity both are fixed into one through cooling; So, can make easily and reduce cost, can obtain the high heat exchanger of save space and reliability.
(second embodiment)
This embodiment adopts the heat exchanger of first embodiment condenser and evaporimeter the two or any side in the air conditioner of the freeze cycle be linked in sequence by refrigerant piping compressor, condenser, expansion valve and evaporimeter.
According to this embodiment, can obtain the high air conditioner of save space and reliability.
