Definitions
- the present invention relates to side plates for use in heat exchanges, heat exchangers and a process for fabricating the heat exchanger.
- Heat exchangers are widely known which comprise a pair of headers arranged as spaced apart from each other, a plurality of flat heat exchange tubes arranged in parallel as spaced apart from one another between the headers and each having opposite ends joined to the respective headers, two side plates disposed externally of and at a distance from the respective flat heat exchange tubes at opposite ends of the tube arrangement, and corrugated fins arranged between adjacent heat exchange tubes and between each side plate and the end exchange tube adjacent thereto.
- Such heat exchangers are fabricated in the process to be described below.
- the process includes arranging a plurality of flat heat exchange tubes in parallel as spaced from one another with two side plates arranged externally of and at a distance from the respective flat heat exchange tubes at opposite ends of the heat exchanger and arranging corrugated fins between adjacent heat exchange tubes and between each side plate and the end exchange tube adjacent thereto, placing opposite ends of the heat exchange tubes into corresponding insertion holes in a pair of headers, arranging pressure plates elongated longitudinally of the side plate on the respective side plates externally thereof, binding the pressure members, the side plates, the heat exchange tubes and the corrugated fins together with fastening members, and brazing the headers to the heat exchange tubes, and the corrugated fins to adjacent heat exchange tubes and the side plates.
- a heat exchanger wherein the corrugated fins are prevented form slipping out of the space between adjacent heat exchange tubes is known.
- This heat exchanger has a projection provided on one of the heat exchange tube and the corrugated fin or between the heat exchange tube and the corrugated fin over the entire length of the tube.
- the projection locally causes a sacrificial deformation in bent portions of the corrugated fin, and the corrugated fin in this state is brazed to the heat exchange tube (see, for example, JP-A No. 1995-55379, claims).
- corrugated fin between each end exchange tube and the side plate adjacent thereto also has the problem that each end of the fin will readily slip off, whereas no measure has been found out for solving this problem. Even if the technique of the above publication is applied to the side plate and the corrugated fin, the fin becomes locally deformed, consequently making the heat exchanger appear unsightly.
- An object of the present invention which has been accomplished in view of the above situation, is to provide a side plate for use in heat exchangers of the type described above which is adapted to prevent the corrugated fin from slipping off from between the side plate and the heat exchange tube adjacent thereto in fabricating the heat exchanger, the heat exchanger and a process for fabricating the heat exchanger.
- the present invention includes the following modes.
- a side plate for use in heat exchangers comprising a pair of headers arranged as spaced apart from each other, a plurality of flat heat exchange tubes arranged in parallel as spaced apart from one another between the headers and each having opposite ends joined to the respective headers, the side plate disposed externally of and at a distance from the flat heat exchange tube at each of opposite ends of the tube arrangement, and corrugated fins arranged between adjacent heat exchange tubes and between the side plate and the end exchange tube adjacent thereto,
- a side plate for use in heat exchangers 6 wherein the second projection is circular and 1 to 4 mm in diameter.
- a heat exchanger comprising a pair of headers arranged as spaced apart from each other, a plurality of flat heat exchange tubes arranged in parallel as spaced apart from one another between the headers and each having opposite ends joined to the respective headers, a side plate disposed externally of and at a distance from the flat heat exchange tube at each of opposite ends of the tube arrangement, and corrugated fins arranged between adjacent heat exchange tubes and between the side plate and the end exchange tube adjacent thereto, the side plate being one according to any one of above para. 1) to 10).
- a refrigeration cycle comprising a compressor, a condenser and an evaporator, the condenser comprising a heat exchanger set forth in the above para. 11).
- a refrigeration cycle comprising a compressor, a condenser and an evaporator, the evaporator comprising a heat exchanger set forth in the above para. 11).
- the side plate for heat exchangers which is described in the above para. 1) prevents opposite end portions of the corrugated fin from slipping off from between the side plate and the heat exchange tube at each end of the fin arrangement when the heat exchanger is fabricated. Stated more specifically, when the pressure members, side plates, heat exchange tubes and corrugated fins are bound together with fastening members in fabricating the heat exchanger by the process set forth in the para. 15), the side plates are deflected toward the heat exchange tubes by the pressure members which press the projections, whereby opposite end portions of the side plates 5 are deflected toward the refrigerant tubes 4 . As a result, opposite end portions of the corrugated fin 6 are held between the side plate 5 and the tube 4 with a great force and are prevented from slipping off.
- Opposite end portions of the corrugated fin as held between the side plate described in the para. 3) and the refrigerant tube can be clamped with an increased force and reliably prevented from slipping off.
- the side plate can be deflected over an increased length, with the result that opposite end portions of the corrugated fin can be reliably prevented from slipping off from between the side plate and the refrigerant tube.
- the corrugated fin can be reliably prevented from slipping off between the first-mentioned projection and the second projection.
- the side plate described in para. 9) exhibits the same advantage as the one described in para. 4).
- the side plate described in para. 10) exhibits the same advantage as the one described in para. 5).
- FIG. 1 is an overall perspective view showing a condenser having side plates of the present invention.
- FIG. 2 is a fragmentary front view partly broken away and showing the condenser.
- FIG. 3 is a perspective view showing the side plate of the invention with an intermediate portion thereof omitted.
- FIG. 4 is a perspective view showing a process for fabricating the condenser of FIG. 1 , pressure members, the side plates, refrigerant tubes and corrugated fins being shown as bound together with fastening members.
- FIG. 5 is a fragmentary front view partly broken away showing the components in the same state as in FIG. 4 .
- the term “aluminum” includes aluminum alloys in addition to pure aluminum.
- the upper and lower sides, and the left- and right-hand sides of FIG. 1 will be referred to as “upper,” “lower,” “left” and “right,” respectively, and the downstream side with respect to the direction of flow of air through the condenser (the direction indicated by the arrow X in FIG. 1 ) will be referred to as “front,” and the opposite side as “rear.”
- FIGS. 1 and 2 show a condenser which is adapted for use in motor vehicle air conditioners and wherein side plates of the invention are used.
- FIG. 3 shows the side plate.
- FIGS. 4 and 5 show a process for fabricating the condenser.
- the refrigerant tube 4 to be used comprises an extruded tube, electroresistance-welded tube or the like.
- the refrigerant tube 4 to be used may be one made from a metal plate comprising two flat wall forming portions interconnected by a connecting portion, and two side wall forming portions each projecting from the flat wall forming portion integrally therewith at the side edge thereof opposite to the connecting portion, by bending the metal plate to the shape of a hairpin at the connecting portion and brazing the side wall forming portions to each other.
- the number of refrigerant tubes 4 between the inlet pipe 7 and the first partition plate 9 , the number of refrigerant tubes 4 between the first partition plate 9 and the second partition plate 10 and the number of refrigerant tubes 4 between the second partition plate 10 and the outlet pipe 8 decrease stepwise from above downward to provide groups of channels.
- the refrigerant flows through the condenser 1 zigzag via the units of channel groups.
- Each refrigerant tube 4 has opposite ends placed into respective insertion holes 11 formed in the headers 2 , 3 and brazed to the respective headers 2 , 3 .
- Each side plate 5 has opposite ends also placed into respective insertion holes 12 formed in the headers 2 , 3 and brazed to the respective headers 2 , 3 .
- the upper side plate 5 is provided at each of opposite end portions thereof with a plurality of, i.e., two, first projections 13 projecting from upper side thereof and spaced apart toward the front or rear, i.e., widthwise of the side plate.
- the distance A (see FIG. 2 ) from each first projection 13 to the header 2 or 3 proximate thereto is preferably up to 135 mm.
- the upper side plate 5 is also provided on its upper side with a plurality of, i.e., two, second projections 14 projecting upward, spaced apart widthwise of the plate and positioned inwardly of each pair of first projections 13 with respect to the lateral direction, i.e., longitudinally of the side plate 5 .
- the distance B (see FIG. 2 ) between the first projections 13 and the second projections 14 at each end portion of the plate 5 is preferably up to 30 mm.
- Each of the two first projections 13 and the corresponding second projection 14 are in the same position with respect to the widthwise direction of the plate 15 .
- the first projections 13 and the second projections 14 each have a height preferably of 0.3 to 1 mm.
- the first and second projections 13 , 14 are each circular when seen from above and have a diameter preferably of 1 to 4 mm.
- the upper side plate 5 has an upright wall 5 a at each of its front and rear side edges integrally therewith.
- the upper side plate 5 has at each of its left and right ends a projecting portion 5 c extending laterally outward from the main portion thereof integrally therewith with a stepped potion 5 b formed therebetween, and positioned at a slightly lower level than the main portion.
- the projecting portion 5 c has an insert 5 d to be placed into the insertion hole 12 of the header 2 or 3 .
- the lower side plate 5 is symmetrical with the upper side plate 5 about a horizontal center line of the condenser 1 .
- These side plates 5 are each formed as an integral piece from an aluminum plate by press work.
- the condenser 1 described above is used, for example, in motor vehicle air conditioners for providing a refrigeration cycle along with a compressor and an evaporator.
- the condenser 1 is fabricated by the process to be described below with reference to FIGS. 4 and 5 .
- a plurality of refrigerant tubes 4 are arranged in parallel as spaced from one another, two side plates 5 are arranged externally of and at a distance from the respective refrigerant tubes 4 at opposite ends of the arrangement with their projections 13 , 14 facing outward, and corrugated fins 6 are arranged between adjacent refrigerant tubes 4 and between each side plate 5 and the end exchange tube 4 adjacent thereto.
- Opposite ends of the refrigerant tubes 4 are then placed into respective corresponding insertion holes 11 in two headers 2 , 3 , and the inserts 5 d of the side plates 5 at their opposite ends are placed into the respective corresponding insertion holes 12 in the headers 2 , 3 .
- a first partition plate 9 is placed into the first header 2 , and a second partition plate 10 into the second header 3 .
- each side plate 5 between the upright walls 5 a thereof is then placed a pressure member 20 elongated longitudinally of the side plate 5 so as to be in contact with all the projections 13 , 14 thereof.
- the pressure member 20 is made, for example, from stainless steel, and has a length approximately equal to the distance between opposite stepped portions 5 b of the side plate 5 and greater than the spacing between the first projections 13 at the left and right end portions of the side plate 5 .
- the pressure members 20 , side plates 5 , refrigerant tubes 4 and corrugated fins 6 are bound together with fastening members 21 each in the form of a belt.
- the assembly is thus bound at locations closer to the respective headers 2 , 3 than the first projections 13 in the respective end portions of the side plate, and at locations inwardly of the second projections 14 with respect to the longitudinal direction of the side plate 5 . Consequently, the first projections 13 and the second projections 14 are pressed by the pressure members 20 owing to the force resulting from this binding (see arrows in FIGS. 4 and 5 ), whereby opposite end portions of the side plates 5 are deflected toward the refrigerant tubes 4 (see FIG. 5 ).
- corrugated fin 6 is held between the side plate 5 and the tube 4 with a great force and are prevented from slipping off. If the corrugated fin 6 is not smaller than 500 mm in length, opposite end portions thereof especially readily slip off from between the side plate 5 and the refrigerant tube 4 , whereas if the distance A between the first projection 13 and the header 2 or 3 at each end is up to 135 mm, the corrugated fin 6 is clamped with an increased force owing to the deflection of the side plate 5 , whereby the opposite end portions of the corrugated fin 6 are reliably prevented from slipping off from between the side plate 5 and the refrigerant tube 4 .
- the opposite end portions of the corrugated fin 6 are likely to slip off from between the side plate 5 and the refrigerant tube 4 . Further since the distance between the first projection 13 and the second projection 14 is up to 30 mm, the corrugated fin 6 is prevented from slipping off between the projections 13 , 14 . If this distance is in excess of 30 mm, the fin 6 is likely to slip off between these projections 13 , 14 .
- the first projections 13 and the second projections 14 are 0.3 to 1 mm in height, so that opposite end portions of the fin 6 can be reliably prevented from slipping off from between the side plate 5 and the refrigerant tube 4 without being deformed plastically.
- the projections are less than 0.3 mm in height, the amount of deflection of the side plate 5 is small, permitting the side plate 5 and the refrigerant tube 4 to clamp the corrugated fin 6 with a small force and rendering opposite end portions of the fin 6 likely to slip off.
- the side plate 5 will deflect to excess, plastically deforming the corrugated fin 6 to impair the heat exchange performance of the condenser 1 fabricated.
- the first projections 13 and the second projections 14 are circular when seen from above and are 1 to 4 mm in diameter. Accordingly, opposite end portions of the corrugated fin 6 can be reliably prevented from slipping off from between the side plate 5 and the refrigerant tube 4 without causing plastic deformation of the fin 6 .
- the two headers 2 , 3 are brazed to the refrigerant tubes 4 , the two headers 2 , 3 to the side plates 5 , the corrugated fins 6 to adjacent refrigerant tubes 4 or to the side plate 5 , and the headers 2 , 3 to the respective partitions 9 , 10 at the same time.
- the inlet pipe 7 is welded to the first header 2 , and the outlet pipe 8 to the second header 3 . In this way, a condenser 1 is fabricated.
- the inserts 5 d provided at opposite ends of the side plate 5 are placed into the corresponding insertion holes 12 formed in the respective headers 2 , 3 , whereas this construction is not limitative; the ends of the side plate 5 need not always be inserted into the headers. Of course, in this case, the insertion holes are not formed.
- the heat exchanger comprising the side plate of the invention is usable also as an evaporator for providing a refrigeration cycle along with a compressor and a condenser for use in motor vehicle air conditioners.
- the heat exchanger is further usable as a heater for motor vehicles.
- the invention provides a side plate for use in heat exchangers which comprise a pair of headers arranged as spaced apart from each other, a plurality of flat heat exchange tubes arranged in parallel as spaced apart from one another between the headers and each having opposite ends joined to the respective headers, two side plates disposed externally of and at a distance from the respective flat heat exchange tubes at opposite ends of the tube arrangement, and corrugated fins arranged between adjacent heat exchange tubes and between each side plate and the end exchange tube adjacent thereto.
- the side plate is suitable for preventing the corrugated fin from slipping off in fabricating the heat exchanger.
