The specific embodiment
Followingly example of the present invention is described with reference to drawing.
(example 1)
Fig. 1 is the front view before the heat exchanger bending forming of the invention process form 1, Fig. 2 be behind the bending forming horizontal plane cut off the bight, from above being seen phantom.In Fig. 1, only be decorated with the part corrugated fin.In addition, the heat exchanger of this example 1 is different from the above-mentioned heat exchanger of example in the past, and bending forming part 5 is the L font at 1 position global shape.
The heat exchanger of this invention has: a plurality of flat tubes 2 that above-below direction is arranged in parallel; At 2 adjacent of each flat tubes corrugated fin 4 as heat exchange fins is arranged, at the two ends of flat tube 2 lower water tank 3A, 3B have been installed, whole flat tubes 2 and last lower water tank 3A, 3B are connected.
In addition, because the spacing of having dwindled the flat tube 2 of bending forming part 5, so as shown in Figure 2, behind the bending forming, the circulation of air of this part is interrupted, can promote to be equipped with the circulation of air of part of the flat tube 2 of corrugated fin 4.
And the circulation of air of this part is not covered fully, and flat tube 2 also helps heat exchange, therefore, reduces heat-exchange capacity hardly, does not increase flowing resistance.In addition, because of need not the back manufacturing procedure, can not cause in the integral body manufacturing of relevant heat exchanger, spending time.
(example 2)
Fig. 3 be front view, the Fig. 4 before the heat exchanger bending forming of example 2 of the present invention be behind the bending forming horizontal plane cut off the bight, from above being seen phantom.
In the following description, omitted the explanation that repeats mutually with the explanation of embodiment 1 about overall structure of heat exchanger etc.
As shown in Figure 4, when flat tube 2 was bent to the L font, the spacing in the outside of bending forming part 5 broadened, and inboard spacing narrows down.Therefore, if between adjacent flat tube 2, connect corrugated fin 4, the outside elongation of corrugated fin 4, therefore inboard compression, but because corrugated fin 4 has rigidity, can resist suffered compression stress, tensile force and not crooked.
Heat exchanger of the present invention, about bending forming part 5, above-mentioned flat tube 2 sets by the spacing greater than other parts.Therefore, identical with the heat exchanger line part between the adjacent flat tube 2 of this part, be provided with corrugated fin 4, the corrugated fin 4 of this part is different with the heat exchanger line part, and just single face links to each other with flat tube 2.
Thereby when flat tube 2 bending formings, the counter-bending resistance because of compression, the stretching that has lost corrugated fin 4 produces so reduced the rigidity of bending forming part 5, only needs the power of bending machining storage tank 3A, 3B, also with regard to easier bending forming.
In addition, as shown in Figure 4, behind the bending forming, the shape of the heat exchanger of this part almost is identical form with heat exchanger line part shape, therefore, has the reduction of heat exchanger ability, the increase of flowing resistance hardly.And,, and can not cause in the integral body manufacturing of relevant heat exchanger, spending time because of manufacturing procedure after need not.
And, in this example, only use a kind of corrugated fin 4 owing to whole heat exchanger, for bending forming part 5, flat tube 2 herein spacing is set greater than other parts, do not change the spacing of flat tube 2, even heat exchanger lengthwise dimension (size between the flat tube 2 of adjacency) is set than the little corrugated fin 4 of other heat exchanger line part in bending forming part 5, also will plays identical effect.
(example 3)
Fig. 5 is the front view before the heat exchanger bending forming of the invention process form 3, Fig. 6 be behind the bending forming horizontal plane cut off the bight, from above being seen phantom.
In the following description, omitted the explanation that repeats mutually with the explanation of example 1 or 2 about overall structure of heat exchanger etc.
Heat exchanger of the present invention, for bending forming part 5, the depth size L of the direction of will facining the wind (direction of arrow of Fig. 6) is arranged at less than the corrugated fin 41 of the depth size M of other heat exchanger line part on the position of center line X of storage tank 3A, 3B.
Therefore, when bending forming, the counter-bending resistance that produces because of compression, the stretching that has lost corrugated fin 41, thus reduced the rigidity of bending forming part 5, and the easy bending forming that becomes.
In addition, because the shape of the heat exchanger of this part almost is identical form with heat exchanger line part shape, therefore, there are the reduction of heat exchanger ability, the increase of flowing resistance hardly.And,, and can not cause in the integral body manufacturing of relevant heat exchanger, spending time because of manufacturing procedure after need not.
(example 4)
Fig. 7 is the front view before the heat exchanger bending forming of the invention process form 4, Fig. 8 be behind the bending forming horizontal plane cut off the bight, from above being seen cutaway view.
In the following description, omitted the explanation that repeats mutually with example 1 or 2,3 explanation about overall structure of heat exchanger etc.
Heat exchanger of the present invention, for bending forming part 5, flat tube 2 and corrugated fin 4 are not set, be arranged at storage tank 3A, 3B position of center line be the shield 6 of main material with aluminium or zinc, about end with flat tube 2, be connected with above-mentioned storage tank 3A, 3B at upper and lower side.
Therefore, when bending forming, the counter-bending resistance because of compression, the stretching that has lost corrugated fin 4 produces so reduced the rigidity of bending forming part 5, only needs the power of bending machining storage tank 3A, 3B, easier bending forming.
In addition,,, reduced actual heat exchanger aperture area, produced the reduction of heat-exchange capacity, the increase of flowing resistance simultaneously owing to do not have flat tube 2, corrugated fin 4 in bending forming part 5 in the present invention with routine identical in the past.But, in the operation of the brazed metal heat exchanger of assembling,, therefore not needing the back manufacturing procedure owing to be the structure of assembling shield 6, can not cause in the integral body manufacturing of relevant heat exchanger, spending time.
In above-mentioned each example, because of having used flat tube, even the wall thickness of pipe is identical, because of caliber is little, so withstand voltage big, during carbon dioxide coolant that especially working pressure is high, the various embodiments described above are more effective.
And, because of the pipe internal volume of flat tube is little, can reduce the amount of cold-producing medium, when the HC cold-producing medium that uses combustible refrigerant etc., the heat exchanger of above-mentioned each example is effective.
