Abstract
Description
- The invention relates to manifolds having multiple passages. More specifically, the invention relates to extruded manifolds with multiple passages and cross-counterflow heat exchangers incorporating such manifolds.
- Air-cooling (or heating) cross-counterflow heat exchangers are often used in applications where space limitations restrict the surface area of the heat exchanger. Cross-counterflow heat exchangers typically include a plurality of stacked, assembled modules, with each module including a pair of spaced manifolds interconnected by a plurality of spaced and parallel tubes. The modules are stacked such that air flows in a direction perpendicular to the face of the heat exchanger, and air fins are disposed between adjacent pairs of tubes for transferring heat from the tubes to the passing air.
- Another type of cross-counterflow heat exchanger assembly is shown in
US Patent No. 5,941,303, issued to James D. Gowan on August 24, 1998 and hereinafter referred to as Gowan '303. Gowan '303 discloses a cross-counterflow heat exchanger comprising a pair of spaced and continually extruded manifolds. Each of the manifolds includes an interior, and each of the manifolds includes at least one dividing wall to divide the interior into a plurality of flow paths. A plurality of tubes extends and establishes fluid communication between the pair of manifolds. Each of the tubes includes at least one tube divider to separate it into a plurality of passages. - In summary, the invention provides a manifold for use in a heat exchanger assembly and a method of forming the manifold. The method starts with the step of separately forming a first member at least partially defining an interior and having a spaced set of first tube slots and a second member having a wall positioned against the first tube slots and dividing the interior into a plurality of chambers. The method is finalized with the step of permanently fixing the first member to the second member to define a first manifold after the separately forming step.
- Advantages of the present invention will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
-
Figure 1 is a perspective and exploded view of the exemplary embodiment of the invention; -
Figure 2 is a cross-sectional view of the first and second manifolds and the tubes taken along line 2-2 ofFigure 1 ; -
Figure 3 is a front view of the first member of the exemplary embodiment of the invention; -
Figure 4 is a front view of the second member of the exemplary embodiment of the invention; and -
Figure 5 is a cross-sectional view of one of the tubes taken along line 5-5 ofFigure 2 . - Referring to
Figure 1 , aheat exchanger assembly 20 is generally shown and includes afirst member 22 at least partially defining an interior. Referring toFigure 3 , in the exemplary embodiment, thefirst member 22 is a channel having a cross-section defining a U-shape and presentingarms 24 integrally connected to abase 26 and extending forwardly toarm ends 28. Referring again toFigure 1 , thebase 26 of thefirst member 22 presents a plurality offirst tube slots 30 longitudinally spaced from one another. Thefirst tube slots 30 can be formed by conventional machining methods including stamping, grinding, or milling. - Referring to
Figure 2 , theassembly 20 includes asecond member 32 comprising aplate 34 and awall 36 extending transversly to theplate 34. Theplate 34 extends between and engages the arm ends 28 of thefirst member 22 and thewall 36 engages thebase 26 of thefirst member 22 to divide the interior into a plurality ofchambers Figure 1 , thesecond member 32 includes a plurality of notches being spaced to correspond with thefirst tube slots 30 of thefirst member 22. Thesecond member 32 is permanently fixed to thefirst member 22 to define anfirst manifold 42, which is generally indicated. In the exemplary embodiment, thesecond member 32 is brazed to thefirst member 22, but any other method of permanently fixing the first andsecond members - Other geometries for the first and
second members - The
assembly 20 also includes a plurality oftubes 44 extending between first andsecond tube ends first tube end 46 of eachtube 44 is disposed in one of thefirst tube slots 30 of thefirst manifold 42. Referring toFigure 5 , eachtube 44 defines at least onetube divider 50 disposed in thetube 44 and extending between the first andsecond tube ends first passage 52 in fluid communication with one of thechambers second passage 54 in fluid communication with the other of thechambers first tube end 46 abuts and is permanently fixed to thewall 36 of thesecond member 32. - The
assembly 20 further includes asecond manifold 56 extending in spaced and parallel relationship with thefirst manifold 42. Thesecond manifold 56 presents a plurality ofsecond tube slots 58 spaced from each other to correspond with the spacing of thefirst tube slots 30 of thefirst manifold 42. Thesecond tube end 48 of eachtube 44 extends into and engages the correspondingsecond tube slot 58 to establish fluid communication between thetubes 44 and thesecond manifold 56. Thesecond manifold 56 directs the flow of coolant from one of thepassages tubes 44 to the other to define a two-pass cross-counterflowheat exchanger assembly 20. - In the exemplary embodiment, the
tubes 44 and the first andsecond tube slots flat sides 60 and round ends. However, thetubes 44 may be have any shape capable of transmitting a fluid between the first andsecond manifolds flat sides 60 ofadjacent tubes 44 are spaced from one another to define a plurality of air passages for the flow of air therebetween. Acorrugated air fin 62 is disposed between and brazed to the parallelflat sides 60 ofadjacent tubes 44 and extends between the first andsecond manifolds - One of the
chambers first manifold 42 includes aninput 64 to define aninput chamber 38 for receiving a fluid, and the other of thechambers output 66 to define anoutput chamber 40 for dispensing the coolant after it has passed through theheat exchanger assembly 20. In the preferred embodiment, theinput 64 is disposed on the chamber that is downstream of the direction of the flow of air and theoutput 66 is disposed on the chamber upstream of theinput chamber 38. Theinput 64 andoutput 66 may have any shape capable of delivering a fluid to the input andoutput chambers first manifold 42. - The embodiment shown in the drawings is for a two-pass counter crossflow heat exchanger assembly. However, the manifolds and tubes may be designed to allow for more than two passes by inserting walls in either or both of the first and second manifolds and including a plurality of tube dividers in each tube. For example, in a three-pass heat exchanger assembly, the second member has one wall to divide the first manifold into two chambers, the second manifold has one wall, and each tube has two tube dividers.
- The invention also includes a method of forming a
first manifold 42 for use in aheat exchanger assembly 20. The method starts with the step of separately forming afirst member 22 at least partially defining an interior and asecond member 32. Thefirst member 22 has a spaced set offirst tube slots 30 and thesecond member 32 has awall 36 that is positioned against thefirst tube slots 30 to divide the interior into a plurality ofchambers first member 22 to thesecond member 32 to define afirst manifold 42 after the separately forming step. Thesecond member 32 is preferably extruded and then cut to size, but may also be formed by other methods including casting and machining. In one embodiment, the forming thefirst member 22 is further defined as rolling a flat sheet of material into a channel having a cross-section presenting a U-shape and having abase 26 andarms 24 extending forwardly toarm ends 28. Rolling thefirst member 22 from a flat sheet provides advantages because the flat sheet can be a stock sheet of metal with a brazing material pre-disposed on either side of it. The brazing material then may be used for the step of permanently fixing thefirst member 22 to thesecond member 32. - The method proceeds with the step of forming a plurality of
tubes 44 extending between first andsecond tube ends tube divider 50 extending between the first andsecond tube ends tubes 44 to separate eachtube 44 into afirst passage 52 and asecond passage 54. Referring toFigure 5 , in one embodiment, the forming eachtube 44 is further defined by rolling a flat sheet of material into atube 44 defining atube divider 50. Rolling eachtube 44 from a flat sheet provides advantages because the flat sheet can be a stock sheet of metal having a pre-disposed brazing material on either side of it. The bazing material may then later be used for the step of fixing and sealing the tube ends 46, 48 to the first andsecond tube slots manifolds tube divider 50 may also be used. - The method continues with the step of inserting the
first tube end 46 of eachtube 44 into one of thefirst tube slots 30 of thefirst manifold 42 and abutting the divider of eachtube 44 against thewall 36 of thesecond member 32 to establish fluid communication between thefirst passage 52 of thetubes 44 and one of thechambers first manifold 42 and to establish fluid communication between thesecond passage 54 of thetubes 44 and the other of thechambers first manifold 42. Thefirst tube end 46 of eachtube 44 is then permanently fixed to the associatedfirst tube slot 30first manifold 42. - The method further continues with the step of forming a
second manifold 56 having a set ofsecond tube slots 58 being spaced from each other to correspond with the set offirst tube slots 30 of thefirst manifold 42. The method proceeds with the step of inserting thesecond tube end 48 of each of thetubes 44 into the correspondingsecond tube slot 58 of thesecond manifold 56 to establish fluid communication between the first andsecond passages tube 44 and thesecond manifold 56. - The method is finished with the steps of forming a plurality of
air fins 62 and inserting one of theair fins 62 betweenadjacent tubes 44 to dissipate heat from thetubes 44. In the exemplary embodiment, thetubes 44, manifold, andair fins 62 are all brazed together to define a unifiedheat exchanger assembly 20. - The subject invention provides for a manifold and a cross-counterflow
heat exchanger assembly 20 that is both cheaper and quicker to manufacture than those of the prior art. Many of the traditional methods for forming the tube slots in the first manifold of the Gowan '303 patent must be abandoned in order to avoid interfering with the dividing wall of the first manifold. The first tube slots of the Gowan '303 patent must be milled or grinded, either of which is a very time consuming and costly process. Thefirst tube slots 30 of the present invention may be formed in thefirst member 22 using a variety of manufacturing methods including stamping before the step of permanently fixing the first andsecond members first manifold 42 and of theheat exchanger assembly 20. - While the invention has been described with reference to an exemplary embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
