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 (hereinafter referred to as the leading edge portion of heat-transfer pipe 1), 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, is provided with fin flange part 12 to a face lateral buckling in the two edges of groove 11 one.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, apply hydrophilic coating film and handle (not shown) on the outer surface of plate-shaped fin 10, the heat resisting temperature of this hydrophilic coating film is about 250 ℃.
Then, describe with reference to the flow chart of Fig. 4 manufacture method 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 by 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 on the outer surface and handles after the shape that the raw material punch process with aluminium alloy becomes to stipulate, then by 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, as shown in Figure 5, in each groove 11 of the plate-shaped fin 10 of the fore-and-aft direction of lamination, embed assembling heat-transfer pipe 1 respectively.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 embed heat-transfer pipe 1 in groove 11 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, wish in the heating furnace it is reducing atmosphere or vacuum atmosphere, but under the situation about heating, if apply solder flux in advance on heat-transfer pipe 1, then the wetability of scolding tin becomes good in air atmosphere.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-treated by heating furnace like that by above-mentioned, 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) by capillarity.And by 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 present embodiment sets in advance low-melting soldering-tin layer 4 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 into to having to embed fixing groove 11 and apply hydrophilic coating film in advance for heat-transfer pipe 1 to handle in the plate-shaped fin 10 of aluminium alloy system of ground lamination, heat with the low temperature below the heat resisting temperature of hydrophilic coating film, 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 by cooling, so, can make easily and reduce cost, can obtain the high heat exchanger of save space and reliability.
