Description
- The present invention relates to a heat exchanger assembly, more particularly, the present invention relates to an assembly between a condenser and a radiator for a vehicle.
- Generally, vehicles include several heat exchanger elements. Conventionally, an engine cooling system of a vehicle includes a heat exchanger in the form of a radiator to facilitate cooling of an engine of the vehicle. Further, Heating Ventilation and Air-Conditioning (HVAC) system of the vehicle also includes another heat exchanger such as for example, a condenser. The radiator and the condenser are disposed at the front of the vehicle, so that air impinges on and passes through the radiator and the condenser arranged parallel to each other, as the vehicle traverses in a forward direction. The sequence in which the radiator and the condenser or any other heat exchanger are disposed may vary, for example, sometimes the radiator is at the front to first receive the air and in other cases the condenser is at the front to first receive the air. The position of the radiator and the condenser configuring a radiator-condenser assembly can interchange. However, considering packaging, serviceability, pricing and other factors, the radiator and the condenser of the radiator-condenser assembly are arranged to attain a compact configuration, reduced number of fixation points, reduced interface size and achieve proper routing of the fluid flow lines for minimum flow and pressure losses. Often, with use of jumper lines, more fixation points, longer fluid flow lines and larger connector interface size, the packaging of the heat exchange assembly in a confined space becomes complicated and the overall cost of the heat exchanger assembly increases.
- In case of a conventional heat exchanger assembly, such as for example, a radiator-
condenser assembly 01 as illustrated inFIG. 1 , aradiator 10 and acondenser 20 are arranged sequentially parallel to each other. Thecondenser 20 includes inlet andoutlet blocks condenser manifold 24. The inlet andoutlet blocks refrigerant flow lines 40 and deliver vapour refrigerant to and collects condensed refrigerant from the at least onecondenser manifold 24, i.e. performs fluid connection function. The at least one condenser manifold 24 in turn distributes vapour refrigerant to thecondenser core 22 and collects condensed refrigerant from thecondenser core 22. The radiator-condenser assembly 01 further includesseparate brackets condenser 20 over theradiator 10. One end of eachbracket condenser manifold 24 while the other end of eachbracket radiator tank 14. Such configuration of using separate dedicated elements, particularly, inlet andoutlet blocks brackets condenser 20 is disposed downstream of theradiator 10 and therefrigerant flow lines 40 are emanating from upstream of theradiator 10 in the direction of air depicted by arrow R, therefrigerant flow lines 40 are required to go around the at least oneradiator tank 14 to reach the at least onecondenser manifold 24. Such configuration, increases bends along therefrigerant flow lines 40 and overall length of therefrigerant flow lines 40, thereby causing pressure losses in therefrigerant flow lines 40. - Accordingly, there is a need for a heat exchanger assembly, particularly, a radiator-condenser assembly that involves comparatively fewer fixation points and reduced interface size. Further, there is a need for a radiator-condenser assembly that is compact in configuration. Furthermore, there is a need for a radiator-condenser assembly that achieves proper routing of the refrigerant flow lines such that the number of bends along the refrigerant flow lines and length of the refrigerant flow lines is reduced. Still further, there is a need for a radiator-condenser assembly that prevents or reduces pressure losses due to longer refrigerant flow lines or refrigerant flow lines following torturous path. Further, there is a need for a radiator -condenser assembly that provides better serviceability while still addressing packaging issues. Furthermore, there is a need for a radiator-condenser assembly that involves fewer parts, reduced inventory and inventory costs, reduced assembly efforts and assembly time as compared to conventional radiator-condenser assembly and exhibits improved reliability as compared to conventional radiator-condenser assembly.
- An object of the present invention is to provide a heat exchanger assembly, particularly, a radiator-condenser assembly that obviates drawbacks associated with the conventional radiator-condenser assembly.
- Another object of the present invention is to provide a radiator-condenser assembly that involves comparatively fewer fixation points and reduced interface size.

- Disclosed is a radiator-condenser assembly that utilizes a single component that performs mounting and fluid connection functions, particularly, the condenser - radiator assembly uses a common connector that not only forms connection between the radiator and the condenser but also establishes fluid communication between refrigerant flow lines and at least one condenser manifold. Further, the common connector allows refrigerant to pass through at least one radiator tank while bypassing the same. Such configuration of the radiator-condenser assembly, eliminates the drawbacks associated with the conventional assembly, wherein the refrigerant flow lines encounter increased number of bends and increase in length due to the refrigerant flow lines being routed around the at least one radiator tank to reach the at least one condenser manifold. Although, the heat exchanger assembly is explained with an example of the radiator-condenser assembly in the forthcoming description and the accompanying drawings, however, the heat exchanger assembly is also applicable for assembly between any heat exchangers used in vehicle, such as for example, evaporator, condenser, radiator, chiller and the likes. Particularly, the present invention is applicable for heat exchanger assemblies that are required to be compact in configuration, require fewer number of fixation points, reduced interface size and proper routing of the refrigerant flow lines for reduced pressure loss.
- A heat exchanger assembly, particularly, a radiator-
condenser assembly 100 is disclosed in accordance with an embodiment of the present invention.FIG. 2 illustrates a schematic representation of the radiator-condenser assembly 100.FIG 3a illustrates an isometric view of the radiator-condenser assembly 100 as viewed from one side, whereasFIG 3b illustrates an isometric view of the radiator-condenser assembly 100 as viewed from another side, also is illustrated an enlarged view depicting a pair ofconnectors 30. - The radiator-
condenser assembly 100 includes a first heat exchanger, particularly, aradiator 10, a second heat exchanger, particularly, acondenser 20 and at least oneconnector 30. The first heat exchanger includes a first heat exchanger core and either one of at least one first manifold and tank, particularly, theradiator 10 includes aradiator core 12 and at least one radiator tank, simply referred to as at least onetank 14. The second heat exchanger includes a second heat exchanger core and at least one second manifold, particularly, thecondenser 20 includes acondenser core 22 and at least one condenser manifold, simply referred to as at least onemanifold 24.

Further, the at least oneconnector 30 also forms arefrigerant flow passage 32 to establish fluid communication between therefrigerant flow lines 40 and the at least onemanifold 24. However, therefrigerant flow passage 32 is fluidically isolated from the at least onetank 14. More specifically, the at least oneconnector 30 configures fluid communication between therefrigerant flow lines 40 and the at least onemanifold 24, while bypassing the at least onetank 14. Such configuration of the at least oneconnector 30 performs dual functions, firstly, the at least oneconnector 30 performs fluid connection function, i.e. either the at least oneconnector 30 delivers vapour refrigerant to or collects condensed refrigerant from the at least onemanifold 24. Secondly, the at least oneconnector 30 also configures connection between the at least onetank 14 and the at least onemanifold 24, and as such connection between theradiator 10 and thecondenser 20 to reduce the number of fixation points. The radiator-condenser assembly 100 configured with such a configuration of the at least oneconnector 30 has several advantages. Particularly, the radiator-condenser assembly 100 configured with such a configuration of the at least oneconnector 30, involves fewer parts, reduced inventory and inventory costs, reduced assembly time and efforts and improved reliability. Further, the radiator-condenser assembly 100 configured with such a configuration of the at least oneconnector 30 is compact. -
FIG. 4 illustrates an exploded view of the pair ofconnectors 30 forming connection and fluid communication between the at least onetank 14 and the at least onemanifold 24 of theradiator 10 and thecondenser 20 respectively. Eachconnector 30 includes afirst portion 30a and asecond portion 30b. Thefirst portion 30a is secured to the at least onetank 14. Specifically, thefirst portion 30a is integrally formed with the at least onetank 14 as illustrated inFIG. 5a and FIG. 5b . More specifically, the at least onetank 14 is of plastic material and thefirst portion 30a is integrally formed on the at least onetank 14 during manufacturing of the at least onetank 14 by moulding. In case, the at least onetank 14 is of metal, thefirst portion 30a is secured to the at least onetank 14 by at least one of the connection methods selected from a group comprising of brazing, soldering and welding. However, the present invention is not limited to any particular configuration of thefirst portion 30a and method of securing thefirst portion 30a over the at least onetank 14 as far as afirst section 32a of therefrigerant flow passage 32 formed in thefirst portion 30a is bypassing the at least onetank 14. Specifically, thefirst portion 30a includes thefirst section 32a of therefrigerant flow passage 32 that is in fluid communication with therefrigerant flow lines 40 and is fluidically isolated from the at least onetank 14. Specifically, thefirst portion 30a includes a throughaperture 31a defining thefirst section 32a of therefrigerant flow passage 32, wherein a first end of the throughaperture 31a is connected to therefrigerant flow lines 40 whereas an opposite second end of the throughaperture 31a is connected to asecond section 32b of therefrigerant flow passage 32 formed on thesecond portion 30b via a complimentary, hollow plug, simply referred to asplug 31b formed on thesecond portion 30b. Specifically, thefirst portion 30a is connected to and in fluid communication with therefrigerant flow lines 40 by means of complimentary connection elements formed on therefrigerant flow lines 40 and the first end of the throughaperture 31a formed on thefirst portion 30a. Thefirst portion 30a further includes afirst hole 33a, either through or blind for passage of a threaded connection element there through, particularly, abolt 34 there through for facilitating threaded connection between the respectivefirst portion 30a and thesecond portion 30b of therespective connector 30. Furthermore, thefirst section 32a of therefrigerant flow passage 32 formed on thefirst portion 30a is in fluid communication with thesecond section 32b of therefrigerant flow passage 32 formed on thesecond portion 30b. -
FIG. 6a illustrates an isometric view of thesecond portion 30b of theconnector 30 as viewed from one side.FIG. 6b illustrates an isometric view of thesecond portion 30b of theconnector 30 as viewed from another side. Thesecond portion 30b is secured to thefirst portion 30a and the at least onemanifold 24. Specifically, thesecond portion 30b is integrally formed with the at least onemanifold 24. More specifically, the at least onemanifold 24 is of plastic material and thesecond portion 30b is integrally formed on the at least onemanifold 24 during manufacturing of the at least onemanifold 24 by moulding. In case the at least onemanifold 24 is of metal, thesecond portion 30b is secured to the at least onemanifold 24 by at least one of the connection methods selected from a group comprising of brazing, soldering and welding. However, the present invention is not limited to any particular configuration of connection between thesecond portion 30b and the at least onemanifold 24 as far as thesecond portion 30b and the at least onemanifold 24 are in fluid communication with each other. With such configuration, the refrigerant received in thesecond section 32b from thefirst section 32a of therefrigerant flow passage 32 passes through thesecond section 32b along flow direction depicted by arrow B and is delivered to themanifold 24. Thesecond portion 30b includes thesecond section 32b of therefrigerant flow passage 32 that is in fluid communication with thefirst section 32a of therefrigerant flow passage 32 and the at least onemanifold 24. Specifically, thesecond portion 30b includes theplug 31b that is complimentary to and connected to the second end of the throughaperture 31a to configure fluid communication between thefirst section 32a formed in thefirst portion 30a and thesecond section 32b formed in thesecond portion 30b. More specifically, as illustrated inFIG. 7 , theplug 31b is received in the second end of the throughaperture 31a and includes threads for configuring connection between theplug 31b and the second end of the throughaperture 31a formed on thefirst portion 30a. The plug and the hole can be interchangeable disposed on thefirst part 30a and thesecond part 30b. Specifically, the plug is in fluid communication with thefirst section 32a formed on thefirst portion 30a and can extends from thefirst portion 30a instead of extending from thesecond portion 30b and is received in a hole configured on thesecond portion 30b, wherein the hole is in fluid communication with thesecond section 32b formed in thesecond portion 30b. However, the present invention is not limited to whether the plug and the hole are configured thefirst portion 30a or thesecond portion 30b of theconnector 30, as far as the plug and the hole forms fluid communication between thefirst section 32a and thesecond section 32b of therefrigerant flow passage 32 formed on thefirst part 30a and thesecond part 30b of theconnector 30 respectively. - Again referring to
FIG. 7 , thesecond portion 30b further includes asecond hole 33b, particularly a through hole that is aligned with thefirst hole 33a formed on thefirst portion 30a for passage of the threaded connection element, particularly, thebolt 34 as illustrated inFIG. 6c there-through for facilitating threaded connection between the respectivefirst portion 30a and thesecond portion 30b of theconnector 30. Alternatively, thefirst portion 30a and thesecond portion 30b of eachconnector 30 can be integrally formed with respect to each other.FIG. 8a and FIG. 8b illustrates isometric views of thefirst portion 30a and thesecond portion 30b of theconnector 30.FIG. 9a illustrates a front view of thesecond portion 30b of theconnector 30.FIG. 9b illustrates a sectional view of thesecond portion 30b along section line A-A'. - The at least one
connector 30 performs dual function of forming connection between the at least onetank 14 of theradiator 10 and the at least onemanifold 24 of thecondenser 20 and establishing fluid connection between therefrigerant flow lines 40 and the at least onemanifold 24. Accordingly, such configuration of the at least oneconnector 30 of the radiator-condenser assembly 100 reduces the fixation points of the radiator-condenser assembly 100. Particularly, with such configuration, either one of theradiator 10 and thecondenser 20 of the radiator-condenser assembly 100 can be mounted on a vehicle frame as against conventional assembly that requires the radiator as well as the condenser to be mounted on the vehicle frame. Further, in case the refrigerant flow lines are emanating from upstream the radiator in the direction of air, such configuration of the at least oneconnector 30 of the radiator-condenser assembly 100 allows the refrigerant from therefrigerant flow lines 40 to pass through the at least onetank 14 while bypassing the same. Such configuration is advantageous over conventional arrangement of the radiator-condenser assembly, wherein therefrigerant flow lines 40 are required to go around the at least onetank 14 to reach the at least onemanifold 24. Such configuration of the at least oneconnector 30 achieves proper routing of therefrigerant flow lines 40 as the number of bends along therefrigerant flow lines 40 and length of therefrigerant flow lines 40 is reduced and pressure losses due to therefrigerant flow lines 40 being longer or therefrigerant flow lines 40 following torturous path is also reduced. - In accordance with an embodiment of the present invention as illustrated in
FIG. 3a - FIG. 5b , the radiator-condenser assembly 100 includes twoconnectors 30 disposed at asingle manifold 24 disposed at one side of theradiator 10 and thecondenser 20. Thefirst connector 30 is for inlet of refrigerant vapour into thesingle manifold 24 and thesecond connector 30 is for outlet of the condensed refrigerant from thesingle manifold 24 after the refrigerant vapour undergoes condensation in thecondenser core 22. - In accordance with an embodiment of the present invention, the radiator-
condenser assembly 100 includes two connectors, each disposed at twoseparate manifolds 24 disposed at opposite sides of thecondenser core 22. Specifically, a first connector is for inlet of refrigerant vapour into one of the two manifolds and asecond connector 30 is for outlet of the condensed refrigerant from the other of the twoseparate manifolds 24. - In accordance with an embodiment of the present invention, the radiator-
condenser assembly 100 includes a single collector disposed at thesingle manifold 24. The single collector is for inlet of refrigerant vapour into the single manifold and outlet of condensed refrigerant out of thesingle manifold 24. - Several modifications and improvement might be applied by the person skilled in the art to the
heat exchanger assembly 100 as defined above, and such modifications and improvements will still be considered within the scope and ambit of the present invention, as long as the heat exchanger assembly comprises_a first heat exchanger that includes at least one first manifold, a second heat exchanger that includes at least one second manifold and at least one connector formed on at least one of the first manifold and the second manifold. The at least one connector facilitates connection between the second heat exchanger and the first heat exchanger. The at least one connector includes a fluid flow passage that forms fluid communication between heat exchange fluid flow lines and the at least one second manifold. The fluid flow passage is fluidically isolated from the at least one first manifold. - Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings.
