- 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.

Description
- This application is an application filed under 35 U.S.C. §111(a) claiming the benefit pursuant to 35 U.S.C. §119(e) (1) of the filing date of Provisional Application No. 60/477,775 filed Jun. 12, 2003 pursuant to 35 U.S.C. §111(b).
- 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.
- In fabricating the heat exchanger by the above process, it is likely that the corrugated fin will slip out of the space between adjacent heat exchange tubes or between the end exchange tube and the side plate adjacent thereto before the completion of brazing after the components are bound with the fastening members.
- 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).
- The 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.

- 5) A side plate for use in heat exchangers set forth in the above para. 1) wherein the projection is circular and 1 to 4 mm in diameter.
- 6) A side plate for use in heat exchangers set forth in the above para. 1) wherein a second projection is formed at a distance from the projection at each end portion and positioned inwardly of the projection with respect to the longitudinal direction of the side plate.
- 7) A side plate for use in heat exchangers set forth in the above para. 6) wherein the second projection is at a distance of up to 30 mm from the projection at each end portion.
- 8) A side plate for use in heat exchangers set forth in the above para. 6) wherein at least two second projections are provided as spaced apart widthwise of the side plate at each end portion.
- 9) A side plate for use in heat exchangers 6) wherein the second projection is 0.3 to 1 mm in height.

- 12) A refrigeration cycle comprising a compressor, a condenser and an evaporator, the condenser comprising a heat exchanger set forth in the above para. 11).
- 13) A refrigeration cycle comprising a compressor, a condenser and an evaporator, the evaporator comprising a heat exchanger set forth in the above para. 11).
- 14) A vehicle having installed therein a refrigeration cycle set forth in the above para. 12) or 13) as an air conditioner.
- 15) A process for fabricating a heat exchanger set forth in the above para. 11) which includes:
-
- arranging a plurality of flat heat exchange tubes in parallel as spaced from one another, disposing a side plate according to any one of claims 1 to 10 externally of and at a distance from the flat heat exchange tube at each of opposite ends of the tube arrangement with the projections facing outward and arranging corrugated fins between adjacent heat exchange tubes and between the side plate and the end exchange tube adjacent thereto,
- placing opposite ends of the heat exchange tubes into respective corresponding insertion holes formed in a pair of headers,
- arranging a pressure plate having a length greater than the distance between the projections at the opposite end portions of the side plate, on each of the side plates externally thereof in contact with the projections at the opposite end portions,
- binding the pressure members, the side plates, the heat exchange tubes and the corrugated fins together with fastening members on widthwise opposite sides of the side plates, and
- brazing the headers to the heat exchange tubes, and the corrugated fins to adjacent heat exchange tubes and to the side plates.
- 16) A process for fabricating a heat exchanger set forth in the above para. 15) wherein the side plate used is one set forth in any one of para. 6) to 10), and the components are bound with the fastening members at locations closer to the respective headers than the projections at the respective end portions, and at locations inwardly of the respective second projections with respect to the longitudinal direction of the side plate.
- 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

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 inFIG. 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. - With reference to
FIGS. 1 and 2 , the condenser 1 (heat exchanger) for use in motor vehicle air conditioners comprises a pair of aluminum headers 2, 3 extending vertically and arranged in parallel as spaced from each other laterally, a plurality of parallel flat refrigerant tubes 4 (heat exchange tubes) of aluminum arranged as spaced from one another vertically and each having opposite ends joined to the respective headers 2, 3, aluminum side plates 5 disposed externally of and at a distance from the respective refrigerant tubes 4 at opposite ends of the condenser, i.e., above the refrigerant tube 4 at the upper end of the exchanger and below the refrigerant tube 4 at the lower end thereof, corrugated aluminum fins 6 arranged in respective air passing clearances between adjacent refrigerant tubes 4 and in an air passing clearance between each side plate and the end refrigerant tube adjacent thereto and brazed to the adjacent tubes and to the side plate and the end tube, an aluminum inlet pipe 7 welded to a peripheral wall upper end portion of the first header 2, an aluminum outlet pipe 8 welded to a peripheral wall lower end portion of the second header 3, a first partition plate 9 provided inside the first header 2 at a position above the midportion thereof, and a second partition plate 10 provided inside the second header 3 below the midportion thereof. Therefrigerant tube 4 to be used comprises an extruded tube, electroresistance-welded tube or the like. Therefrigerant 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 thefirst partition plate 9, the number ofrefrigerant tubes 4 between thefirst partition plate 9 and thesecond partition plate 10 and the number ofrefrigerant tubes 4 between thesecond partition plate 10 and theoutlet pipe 8 decrease stepwise from above downward to provide groups of channels. Before a refrigerant flowing into the condenser in a vapor phase through the inlet pipe 7 flows out of theoutlet pipe 8 in a liquid phase, 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 theheaders respective headers side plate 5 has opposite ends also placed into respective insertion holes 12 formed in theheaders respective headers - As shown in
FIG. 3 , theupper 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. When theside plate 5 is assembled into the condenser 1, the distance A (seeFIG. 2 ) from eachfirst projection 13 to theheader 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 offirst projections 13 with respect to the lateral direction, i.e., longitudinally of theside plate 5. The distance B (seeFIG. 2 ) between thefirst projections 13 and thesecond projections 14 at each end portion of theplate 5 is preferably up to 30 mm. Each of the twofirst projections 13 and the correspondingsecond projection 14 are in the same position with respect to the widthwise direction of the plate 15. Thefirst projections 13 and thesecond projections 14 each have a height preferably of 0.3 to 1 mm. The first andsecond projections - The
upper side plate 5 has anupright wall 5 a at each of its front and rear side edges integrally therewith. Theupper side plate 5 has at each of its left and right ends a projectingportion 5 c extending laterally outward from the main portion thereof integrally therewith with a steppedpotion 5 b formed therebetween, and positioned at a slightly lower level than the main portion. The projectingportion 5 c has aninsert 5 d to be placed into theinsertion hole 12 of theheader - The
lower side plate 5 is symmetrical with theupper side plate 5 about a horizontal center line of the condenser 1. Theseside 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 . - First, a plurality of
refrigerant tubes 4 are arranged in parallel as spaced from one another, twoside plates 5 are arranged externally of and at a distance from therespective refrigerant tubes 4 at opposite ends of the arrangement with theirprojections corrugated fins 6 are arranged between adjacentrefrigerant tubes 4 and between eachside plate 5 and theend exchange tube 4 adjacent thereto. - Opposite ends of the
refrigerant tubes 4 are then placed into respective corresponding insertion holes 11 in twoheaders inserts 5 d of theside plates 5 at their opposite ends are placed into the respective corresponding insertion holes 12 in theheaders first partition plate 9 is placed into thefirst header 2, and asecond partition plate 10 into thesecond header 3. - On the outer surface of each
side plate 5 between theupright walls 5 a thereof is then placed apressure member 20 elongated longitudinally of theside plate 5 so as to be in contact with all theprojections pressure member 20 is made, for example, from stainless steel, and has a length approximately equal to the distance between opposite steppedportions 5 b of theside plate 5 and greater than the spacing between thefirst projections 13 at the left and right end portions of theside plate 5. - Subsequently, the
pressure members 20,side plates 5,refrigerant tubes 4 andcorrugated fins 6 are bound together withfastening members 21 each in the form of a belt. The assembly is thus bound at locations closer to therespective headers first projections 13 in the respective end portions of the side plate, and at locations inwardly of thesecond projections 14 with respect to the longitudinal direction of theside plate 5. Consequently, thefirst projections 13 and thesecond projections 14 are pressed by thepressure members 20 owing to the force resulting from this binding (see arrows inFIGS. 4 and 5 ), whereby opposite end portions of theside plates 5 are deflected toward the refrigerant tubes 4 (seeFIG. 5 ). As a result, opposite end portions of thecorrugated fin 6 are held between theside plate 5 and thetube 4 with a great force and are prevented from slipping off. If thecorrugated fin 6 is not smaller than 500 mm in length, opposite end portions thereof especially readily slip off from between theside plate 5 and therefrigerant tube 4, whereas if the distance A between thefirst projection 13 and theheader corrugated fin 6 is clamped with an increased force owing to the deflection of theside plate 5, whereby the opposite end portions of thecorrugated fin 6 are reliably prevented from slipping off from between theside plate 5 and therefrigerant tube 4. If the distance A is in excess of 135 mm, the opposite end portions of thecorrugated fin 6 are likely to slip off from between theside plate 5 and therefrigerant tube 4. Further since the distance between thefirst projection 13 and thesecond projection 14 is up to 30 mm, thecorrugated fin 6 is prevented from slipping off between theprojections fin 6 is likely to slip off between theseprojections first projections 13 and thesecond projections 14 are 0.3 to 1 mm in height, so that opposite end portions of thefin 6 can be reliably prevented from slipping off from between theside plate 5 and therefrigerant tube 4 without being deformed plastically. If the projections are less than 0.3 mm in height, the amount of deflection of theside plate 5 is small, permitting theside plate 5 and therefrigerant tube 4 to clamp thecorrugated fin 6 with a small force and rendering opposite end portions of thefin 6 likely to slip off. When the projections are in excess of 1 mm in height, theside plate 5 will deflect to excess, plastically deforming thecorrugated fin 6 to impair the heat exchange performance of the condenser 1 fabricated. Thefirst projections 13 and thesecond projections 14 are circular when seen from above and are 1 to 4 mm in diameter. Accordingly, opposite end portions of thecorrugated fin 6 can be reliably prevented from slipping off from between theside plate 5 and therefrigerant tube 4 without causing plastic deformation of thefin 6. - Subsequently, the two
headers refrigerant tubes 4, the twoheaders side plates 5, thecorrugated fins 6 to adjacentrefrigerant tubes 4 or to theside plate 5, and theheaders respective partitions first header 2, and theoutlet pipe 8 to thesecond header 3. In this way, a condenser 1 is fabricated. - According to the foregoing embodiment, the
inserts 5 d provided at opposite ends of theside plate 5 are placed into the corresponding insertion holes 12 formed in therespective headers side plate 5 need not always be inserted into the headers. Of course, in this case, the insertion holes are not formed. - Although the embodiment described above is a condenser for use in motor vehicle air conditioners, 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.
