The specific embodiment
Below, with reference to the accompanying drawing limit embodiment of the present invention is described.In addition, the present invention is not limited to this embodiment.
(embodiment 1)
Fig. 1 is the side view of the heat exchanger of embodiment 1 of the present invention, and Fig. 2 is the front view of this heat exchanger, and Fig. 3 is the stereogram of the plate wing of this heat exchanger, and Fig. 4 is the side view from seeing with the vertical direction in cross section of the 4-4 line of Fig. 3.
As shown in Figure 1, heat exchanger 1 has: the refrigerant pipe 2 that cold-producing medium is arranged in internal flow; With a plurality of plate wings 3 with the predetermined distance configuration.
As shown in Figure 2, body of the aluminum of refrigerant pipe 2 or aluminium alloy system is formed with straight sections 2a and the 2b of curved tube portion continuously.Refrigerant pipe 2 is the coiled pipe of shape of crawling to be formed with a plurality of mode bending machining in row (about Fig. 2) direction X and layer (Fig. 2 about) direction Y.And refrigerant pipe 2 does not use the tube connector that forms the curved tube 2b of portion, forms a refrigerant flow path.
And, be formed in the slotted hole 4 of plate wing 3 through the 2b of the curved tube portion breakthrough form of refrigerant pipe 2, become the structure that straight sections 2a and plate wing 3 are close to.
As shown in Figure 3, slotted hole 4 has rectangular portion 4d and arc sections 4c, and arc sections 4c forms oval poroid that minor face forms separately continuously in the both sides of rectangular portion 4d.In addition, be provided with at arc sections 4c and be used for being close to the arc sections flange 4a that fixing edge erects moulding with straight sections 2a.The two ends of the length direction of rectangular portion 4d also are provided with the rectangular portion flange 4b that roughly vertical destination edge erects moulding.
That is, in plate wing 3, be provided with a flange that face 3a has cut with respect to plate wing 3 at the both sides and the arc sections 4c of the length direction of rectangular portion 4d.At this, flange is made up of rectangular portion flange 4b and arc sections flange 4a.
Below, in the heat exchanger 1 that constitutes like upper type, its action, effect are described.
At first, when assembling refrigerant pipe 2 and a plurality of plate wing 3, the 2b of curved tube portion inserts also through slotted hole 4.Erect and moulding through the roughly vertical destination edge of rectangular portion flange 4b, the 2b of curved tube portion can not pass through with rectangular portion flange 4b contiguously.If the edge of rectangular portion flange 4b does not erect, then when the 2b of curved tube portion passes through, Yi Bian can on one side rectangular portion flange 4b extruding expansion be passed through therein.Therefore, do not improve intensity, then can not the 2b of curved tube portion be inserted into slotted hole 4 if do not make the thickness of slab thickening etc. of plate wing 3.Therefore, the thickness of slab of plate wing 3 can thin-walled property.
In addition, generally speaking, the 2b of curved tube portion is by flat processing, and formation can be inserted into the size of the width of rectangular portion 4d.With after refrigerant pipe 2 and a plurality of plate wings 3 assemblings, through hydraulic extend pipe etc. refrigerant pipe 2 is carried out hole enlargement, when itself and a plurality of plate wing 3 were close to fixedly, the flatness of the 2b of curved tube portion was back to the original diameter degree.
And then, for rectangular portion flange 4b and arc sections flange 4a integrated molding, need the retractility of plate wing 3, if plate wing 3 is thin-wall parts then is difficult to processing.But, owing to be split up into rectangular portion flange 4b and arc sections flange 4a, so that the processing of integrated molding becomes is easy.Therefore, the thickness of slab of plate wing 3 can thin-walled property.
In addition, owing to be split up into rectangular portion flange 4b and arc sections flange 4a, so be difficult to accumulate water droplet in the seam portion of arc sections flange 4a and rectangular portion flange 4b.If water droplet is accumulated, when the cooling running, be core then with the water droplet, frost is grown up and is become big, arrives to adjacent plate wing 3, makes the inaccessible time of wind path in advance.So the cooling capacity of cooling system reduces, and can not freeze.And even defrost, frost possibly not dissolve yet, and carries out these repeatedly, and frost changes to ice, and heat exchanger 1 integral body becomes ice cube, also can produce the phenomenon that can not freeze fully.
Therefore, the heat transfer area that not only can effectively utilize the slotted hole 4 because of plate wing 3 to disappear, and can avoid frosting to stop up is kept the cooling performance after the defrosting.Consequently, heat exchanger 1 is realized higher reliability, becomes efficient.
In addition, as shown in Figure 4, make the height H b of rectangular portion flange 4b identical with the height H a of arc sections flange 4a.Consequently, simultaneously arc sections flange 4a and rectangular portion flange 4b are carried out deburring processing easily.Under the identical situation of flange height, the frictional resistance of the punch-die of deburring type (punch die) and plate wing 3 materials is identical in arc sections 4c and rectangular portion 4d.Therefore, the processing balance of mould improves, and prolong die life, and cheap heat exchanger 1 can be provided.
In addition, shown in Fig. 1, Fig. 3, under the situation with the 3 vertical settings of plate wing, straight line 31 and the plumb line 30 angulation θ that the rectangular portion flange 4b of the length direction of slotted hole 4 extends are more than following 0 degree of 45 degree.
Under the situation that heat exchanger 1 uses as evaporimeter, near 0 degree, the water droplet during defrosting flows down angle θ more easily, so water droplet is difficult to accumulate more more.In addition, during frosting, the air channel is difficult to obturation, and the reduction of cooling capacity is suppressed.In addition, can avoid frosting to stop up, keep the cooling performance after the defrosting,, become efficient so heat exchanger 1 is realized high reliability.But when angle θ spent near 0, it is big that the coincidence of the refrigerant pipe 2 on the vertical direction becomes, and heat exchanger effectiveness reduces, and the length on the vertical direction of heat exchanger 1 is also elongated.Therefore, be suitably for more than following 0 degree of 45 degree as angle θ.
(embodiment 2)
Fig. 5 is the stereogram of plate wing of the heat exchanger of embodiment 2 of the present invention, and Fig. 6 is the side view from seeing with the vertical direction in cross section of the 6-6 line of Fig. 5.Wherein, in embodiment 2 of the present invention, for embodiment 1 same structure key element, omit detailed explanation.
The height H b of the rectangular portion flange 14b of the slotted hole of plate wing 13 is higher than the height H a of the arc sections flange 14a of slotted hole 4.
Below, action, the effect of use with the heat exchanger 15 of the plate wing 13 of upper type formation described.
At first, higher through the height H b that makes rectangular portion flange 14b than the height H a of arc sections flange 14a, when with slotted hole 4 moulding, can the fin material of die-cut rectangular portion 4d effectively be utilized to the limit.Therefore, heat transfer area increases, so heat exchange performance improves.
In addition, also can cut down the amount of material waste, can use resource effectively.
In addition, through increasing the height H b of rectangular portion flange 14b, when the air through heat exchanger 15 passes through rectangular portion flange 14b, can produce boundary layer leading edge effect and turbulent flow and promote effect.Therefore, heat exchange performance improves, and high performance heat exchanger can be provided.
