Description
- The present invention relates to a heat exchanger, more particularly, the present invention relates to a condenser with a horizontally positioned receiver drier for a vehicle Heating Ventilation and Air-conditioning unit.
EP 1 538 407 A2 discloses a heat exchanger with the features in the preamble of claim 1. - Conventional air conditioning system for example for a vehicle cabin includes a condenser, an evaporator, an expansion device, a compressor and a heater. The compressor pumps refrigerant gas up to a high pressure and temperature. Thereafter, refrigerant gas enters the condenser, where refrigerant gas rejects heat energy to external ambient (through ambient air or a specific low temperature coolant circuit), is cooled, and condenses into liquid phase. Thereafter, the expansion valve regulates refrigerant liquid to flow at proper rate, reducing pressure of the refrigerant liquid due expansion of the refrigerant liquid, and finally, the cooled liquid refrigerant flows to the evaporator, where the cooled liquid refrigerant is evaporated. As the liquid refrigerant evaporates, the refrigerant extracts or absorbs heat energy from air inside an enclosure to be conditioned, specifically, the vehicle cabin in case of a vehicle air conditioning system and the refrigerant returns to the compressor, and the above cycle repeats. In the process, the heat is extracted from inside the vehicle cabin and is rejected outside the vehicle cabin, resulting in cooling of air inside the vehicle cabin.
- Generally, the conventional air conditioning system configured with an expansion valve is also configured with a receiver drier that is disposed in a high-pressure section of the air conditioning system, usually located between a condenser and the expansion valve in the air conditioning loop. Generally, a conventional heat exchanger, particularly, the condenser is configured with the receiver drier along an outlet side of the condenser, particularly, along a length of an outlet collector of a pair of collectors of the condenser. The receiver drier includes a tubular casing in the form of an airtight container with an inlet and an outlet. The inlet receives liquid refrigerant along with some uncondensed refrigerant, debris and incompressible moisture, if any, from a first pass defining a condensing section of the condenser via a first portion of the outlet collector. Whereas, the outlet delivers the liquid refrigerant from which incompressible moisture and debris is removed, to a second pass defining the sub-cooling section of the condenser via a second section of the outlet collector.
- However, there are various drawbacks associated with a condenser of such conventional configuration. Particularly, the conventional condenser with a receiver drier thereof disposed along a collector is bulky. The conventional condenser with the receiver drier thereof disposed along the collector is generally secured to the collector and as such fails to provide flexibility of adjusting position of the receiver drier based on packaging constrains. The conventional condenser with the receiver drier thereof disposed along the collector faces packaging issues due to limited space in a front of the vehicle, the packaging issue is further aggravated in case the vehicle is an electric vehicle, in which the front portion of the electric vehicle is utilized as utility such as for example, a cargo-space or in case the condenser includes two separate cores disposed in a co-planar, non-overlapping configuration to achieve better heat exchange.
- Accordingly, there is a need for a condenser with a receiver drier that can be positioned with respect to collectors of the condenser, to attain a compact configuration and enable packaging thereof in a limited space in front of a vehicle. Further, there is a need for the condenser with the receiver drier that provides flexibility of adjusting position of the receiver drier based on packaging constrains.
- An object of the present invention is to provide a condenser with a receiver drier that can be positioned with respect to collectors of the condenser, to enable packaging thereof in a limited space in front of a vehicle.
- Another object of the present invention is to provide a condenser with a receiver drier that obviates the drawbacks associated with the conventional condenser with a receiver drier thereof disposed vertically along a collector.
- Yet another object of the present invention is to provide a condenser with a receiver drier that provides flexibility of adjusting position of the receiver drier based on packaging constrains.
- In the present description, some elements or parameters may be indexed, such as a first element and a second element. In this case, unless stated otherwise, this indexation is only meant to differentiate and name elements, which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention.

FIG. 1a illustrates a schematic representation of a heat exchanger, particularly, acondenser 100 for an air conditioning system for a vehicle. Thecondenser 100 is generally disposed at a front portion of the vehicle. Thecondenser 100 includes a first condenser section or acondensing section 110 defining a first pass and a second condenser section or asub cooling section 120 defining a second pass and a receiver drier 130. Thefirst condensing section 110 and thesub-cooling section 120 includes a first set ofheat exchange tubes 112 and a second set ofheat exchange tubes 122 respectively. At least the first set ofheat exchange tubes 112 are arranged substantially horizontally. The receiver drier 130 is disposed horizontally and parallel with respect to at least one of the first set ofheat exchange tubes 112 and the second set ofheat exchange tubes 122 and configures fluid communication there between. More specifically, the receiver drier 130 is disposed horizontally and parallel to the set of heat exchange tubes of either the first pass and the second pass that are disposed horizontally. - In accordance with an embodiment of the present invention, the condensing
section 110 and thesub-cooling section 120 are co-planar with respect to each other. Further, the condensingsection 110 and thesub-cooling section 120 are connecting a pair ofcommon collectors baffle common collectors first baffle 142a disposed inside and dividing interior of aninlet collector 140a of the pair ofcommon collectors first portion 144a and asecond portion 146a. Similarly, asecond baffle 142b disposed inside and dividing an interior of anoutlet collector 140b of the pair ofcommon collectors first portion 144b and asecond portion 146b. Thefirst portion 144a of theinlet collector 140a receives vapour refrigerant from afirst inlet 114a along a flow direction as depicted by arrow A and distributes the vapour refrigerant to the first set ofheat exchange tubes 112. In case fluid flow through thecondensing section 110 is I-flow, the vapour refrigerant is condensed as the vapour refrigerant flows through the heat exchange elements of thecondensing section 110 along flow direction depicted by the arrow B. Although, in the accompanying drawings and corresponding description the refrigerant flow through thecondensing section 110 is depicted and described to be as I-flow. However, refrigerant flow through thecondensing section 110 is not limited to I-flow and the flow through thecondensing section 110 can be U-flow or any other flow instead of I-flow. The condensed refrigerant egressing the condensingsection 110 is collected by thefirst portion 144b of theoutlet collector 140b. - The condensed refrigerant, including some refrigerant vapours and incompressible moisture, if any, egresses through the
first portion 144b of theoutlet collector 140b through afirst outlet 114b and enters aninlet 130a to the receiver drier 130 by flowing along flow direction depicted by arrow C. More specifically, a first connecting line in form of a firstflexible conduit 172a connects thefirst outlet 114b formed on thefirst portion 144b of theoutlet collector 140b to theinlet 130a to the receiver drier 130. As the condensed refrigerant passes through the receiver drier 130 along flow direction depicted by arrow D, the incompressible moisture and debris are removed. The condensed refrigerant with moisture and debris removed therefrom, egresses through anoutlet 130b of the receiver drier 130 and enters thesub-cooling section 120 by flowing along flow direction depicted by arrow E. More specifically, a second connecting line in form of a secondflexible conduit 172b connects theoutlet 130b of the receiver drier 130 to asecond inlet 124a formed on thesecond portion 146a of theinlet collector 140a. In accordance with an embodiment of the present invention, the first and the second connecting lines between the receiver drier 130 and thefirst outlet 114b and thesecond inlet 124a can be incorporated into at least one of theinlet collector 140a, theoutlet collector 140b and the receiver drier 130. Specifically, the first and the second connecting lines may be formed as inner channels or side channels, for example formed on walls of at least one of theinlet collector 140a, theoutlet collector 140b and the receiver drier 130. More specifically, the first and the second connecting lines may be coextruded on walls of at least one of theinlet collector 140a, theoutlet collector 140b and the receiver drier 130. Thesecond portion 146a of theinlet collector 140a distributes the refrigerant with moisture and debris removed therefrom to thesub-cooling section 120. In thesub-cooling section 120, the condensed refrigerant is sub-cooled and the sub-cooled refrigerant is collected in thesecond portion 146b of theoutlet collector 140b. The sub cooled refrigerant collected in thesecond portion 146b of theoutlet collector 140b egresses through asecond outlet 124b. -
FIG. 1a - FIG. 4 depict different positions of the receiver drier 130 with respect to thecondensing section 110 and thesub-cooling section 120, wherein thecondensing section 110 and thesub-cooling section 120 are arranged in different configurations with respect to each other. Particularly, in some cases as illustrated inFIG. 1a, FIG. 1b andFIG. 3 , the condensingsection 110 is disposed at the bottom, whereas in other cases as illustrated inFIG. 2a, FIG. 2b andFIG. 4 , thesub-cooling section 120 is disposed at the bottom. - Specifically, the
FIG.1a and FIG.1b illustrate schematic representations of thecondenser 100 in accordance with different embodiments, wherein thecondensing section 110 and thesub-cooling section 120 are co-planar with respect to each other. The receiver drier 130 can be disposed along and adjacent to a longitudinal side of either one of thecondensing section 110 and thesub-cooling section 120. More specifically, as illustrated inFIG. 1a and FIG. 1b , thesub-cooling section 120 is disposed at the top and the receiver drier 130 is disposed along and adjacent to the longitudinal side of either one of thecondensing section 110 and thesub-cooling section 120 respectively. - Further, the
FIG.2a and FIG.2b illustrate schematic representations of thecondenser 100 in accordance with still different embodiments of the present invention, wherein thecondensing section 110 and thesub-cooling section 120 are co-planar with respect to each other. More specifically, as illustrated inFIG. 2a and FIG. 2b , thesub-cooling section 120 is disposed at bottom and the receiver drier 130 is disposed along and adjacent to the longitudinal side of either one of thecondensing section 110 and thesub-cooling section 120 respectively. - Furthermore,
FIG. 3 and FIG. 4 illustrate schematic representations of thecondenser 100 in accordance with yet different embodiments of the present invention, wherein thecondensing section 110 andsub-cooling section 120 are co-planar with respect to each other. The receiver drier 130 can be disposed either one of in-front or behind at least one of thecondensing section 110 and thesub-cooling section 120. More specifically, as illustrated inFIG. 3 , thesub-cooling section 120 is disposed at the top and the receiver drier 130 is disposed in-front of thecondensing section 110 disposed at the bottom. However, the receiver drier 130 can also be disposed behind thecondensing section 110. Further, as illustrated inFIG. 4 , thesub-cooling section 120 is disposed at the bottom and the receiver drier 130 is disposed in-front of thecondensing section 110 that is disposed at the top. However, the receiver drier 130 can also be disposed behind thecondensing section 110. In accordance with another embodiment of the present invention, the receiver drier 130 can be disposed either in front or behind thesub-cooling section 120 instead of thecondensing section 110. - The
first outlet 114b formed on thefirst portion 144b of theoutlet collector 140b is connected to theinlet 130a to the receiver drier 130 via the firstflexible conduit 172a. In accordance with an embodiment of the present invention, the connection between ends of the firstflexible conduit 172a and thefirst outlet 114b formed on thefirst portion 144b of theoutlet collector 140b and theinlet 130a to the receiver drier 130 is a removable connection. Similarly, theoutlet 130b of the receiver drier 130 is connected to thesecond inlet 124a formed on thesecond portion 146a of theinlet collector 140a via the secondflexible conduit 172b. The connection between ends of the secondflexible conduit 172b and thesecond inlet 124a formed on thesecond portion 146a and theoutlet 130b of the receiver drier 130 is a removable connection. With such configuration, the receiver drier 130 connects the pair ofcommon collectors second inlets condensing section 110 and thesub-cooling section 120 formed on the same side of thecondenser 100 respectively and on either sides of the baffle 142a. Instead offlexible conduit 172a connecting thefirst outlet 114b to theinlet 130a of the receiver drier 130 and the secondflexible conduit 172b connecting theoutlet 130b of the receiver drier 130 to thesecond inlet 124a, rigid pipes can be used to form such connections. Such configuration provides flexibility of adjusting position of the receiver drier 130 based on packaging constrains. Such configuration ensures compact configuration and convenient packaging thereof in a limited space without interfering with operation of other elements disposed adjacent to thecondenser 100. Further, such configuration enables quick, convenient replacement or removal of the receiver drier 130 for easy serviceability, as the receiver drier 130 can be replaced or removed for servicing without dismounting the whole condenser assembly. -
FIGS. 5a - FIG. 5b illustrates thecondenser 100 in an accordance with a different embodiment of the present invention. Thecondenser 100 includes a first condenser section or acondensing section 110 defining a first pass, a second condenser section or asub-cooling section 120 defining a second pass and the receiver drier 130. The condensingsection 110 and thesub cooling section 120 are formed as separate cores. The condensingsection 110 includes a first set of heat exchange elements, particularly,heat exchange tubes 112 disposed between a first pair ofcollectors heat exchange tubes 112 are arranged substantially horizontally, wherein edges of the first set of heat exchange tubes define a first air-inlet surface X. Similarly, thesub-cooling section 120 includes a second set of heat exchange elements, particularly,heat exchange tubes 122 disposed between a second pair ofcollectors collectors condensing section 110, whereas the second pair ofcollectors sub-cooling section 120. The receiver drier 130 includes atubular casing 132, theinlet 130a, theoutlet 130b, a desiccant material, a filter and a suction tube held inside thetubular casing 132. As the internal details of the receiver drier 130 and the elements held inside the receiver drier 130 are not within the scope of the present invention, they are hence not shown in the accompanying drawings and are not described in details in the forthcoming description. - Again referring to
FIG. 5a and FIG. 5b , afirst inlet collector 150a of the first pair ofcollectors heat exchange tubes 112 of the first core defining thecondensing section 110. Whereas afirst outlet collector 150b of the first pair ofcollectors heat exchange tubes 112 of the first core defining thecondensing section 110. Similarly, asecond inlet collector 160a of the second pair ofcollectors heat exchange tubes 122 of the second core defining thesub-cooling section 120. Whereas asecond outlet collector 160b of the second pair ofcollectors heat exchange tubes 122 of thesecond core 120 defining thesub-cooling section 120. At least the first pair ofcollectors condensing section 110 and the second core defining thesub-cooling section 120 both are disposed at a front of the vehicle and both directly receive the ram air. Specifically, the first air-inlet surface (X) and the second air-inlet surface (Y) do not overlap when viewed in a direction perpendicular to the first air-inlet surface (X) and when viewed in a direction perpendicular to the second air-inlet surface (Y). More specifically, the first core defining thecondensing section 110 and the second core defining thesub-cooling section 120 are so arranged with respect to each other such that refrigerant flow through thecondensing section 110 and thesub-cooling section 120 is series flow, whereas air flow through thecondensing section 110 and thesub-cooling section 120 is parallel flow. The condenser with first core defining thecondensing section 110 and the second core defining thesub-cooling section 120 disposed non-overlapping configuration with respect to each other exhibits improved heat exchange efficiency as compared to condenser with the first core and the second core disposed in overlapping configuration, due to both cores in the non-overlapping configuration being directly exposed to air. Specifically, condenser with the first core and the second core disposed in overlapping configuration exhibit reduced heat exchange efficiency as the first core acts as a barrier to air flow to the second core placed behind the first core in the overlapping configuration. However, condenser disposed at front of the vehicle, with non-overlapping cores occupies comparatively more space in lateral direction of the vehicle as compared to condenser with overlapping cores and cause packaging issues for the other elements such as the receiver drier 130. Accordingly, there is a need for arranging the receiver drier 130 in compact configuration to address the packaging issues. Also, such configuration of the first core and the second core disposed in non-overlapping configuration with respect to each other enables compact packaging of the cores along longitudinal direction of the vehicle. Further, such configuration of the first core and the second core disposed in non-overlapping configuration with respect to each other enables mounting of both cores in the left and right wheelbases of the vehicle or generally apart from each other along the width of the vehicle. - The first core defining the
condensing section 110 receives refrigerant vapours and delivers condensed refrigerant along with some incompressible moisture and uncondensed refrigerant and debris, if any, to theinlet 130a to the receiver drier 130. The receiver drier 130 is disposed horizontally and parallel to the first set ofheat exchange tubes 112 to address the packaging issue arising due to the first core and the second core arranged in non-overlapping configuration with respect to each other. The receiver drier 130 removes incompressible moisture and debris from the refrigerant vapours passing there through and separates the condensed refrigerant from the vapour refrigerant. The second core defining thesub-cooling section 120 is disposed downstream of and is connected to theoutlet 130b of the receiver drier 130 in the fluid flow direction. The receiver drier 130 is generally connected to the second core defining thesub-cooling section 120 by brackets or support elements. The second core defining thesub-cooling section 120, sub-cools the condensed refrigerant from the first core defining thecondensing section 110 from which incompressible moisture and uncondensed refrigerant is removed by the receiver drier 130. The first core defining thecondensing section 110 and the second core defining thesub-cooling section 120 may be connected to each other to impart strength to the overall structure. In one embodiment, the first core and the second core are connected by brackets or support elements. In accordance with another embodiment, the first core and the second core are independently mounted on vehicle frame. However, the present invention is not limited to any particular configuration and placement of the second core defining thesub-cooling section 120 with respect to the first core defining thecondensing section 110, as far as the first air-inlet surface (X) and the second air-inlet surface (Y) do not overlap when viewed in a direction perpendicular to the first air-inlet surface (X) and when viewed in a direction perpendicular to the second air-inlet surface (Y). The air flow through thecondensing section 110 and thesub-cooling section 120 is parallel flow, particularly, both thecondensing section 110 and thesub-cooling section 120 directly receives the ram air. - The first core defining the
condensing section 110 receives the refrigerant vapour from thefirst inlet collector 150a. Thefirst inlet collector 150a includes afirst inlet 152a configured thereon and in fluid communication therewith. Thefirst inlet 152a supplies refrigerant vapour to thefirst inlet collector 150a. More specifically, referring to theFIG. 5a , the refrigerant vapour enters thefirst inlet collector 150a from thefirst inlet 152a along a flow direction depicted by arrow A. Thereafter, thefirst inlet collector 150a in conjunction with corresponding header distributes the vapour refrigerant in the first core defining thecondensing section 110. In case fluid flow through the first core defining thecondensing section 110 is I-flow, the vapour refrigerant is condensed as the vapour refrigerant flows through the heat exchange elements of the core defining thecondensing section 110 along flow direction depicted by the arrow B. Although, in the accompanying drawings and corresponding description, the refrigerant flow through the heat exchange elements of the core defining thecondensing section 110 is depicted and described as I-flow. However, refrigerant flow through the core defining thecondensing section 110 is not limited to I-flow and the flow through the core defining thecondensing section 110 can be U-flow or any other flow instead of I-flow. As the vapour refrigerant flows through the first set ofheat exchange tubes 112 of the first core defining thecondensing section 110 as depicted by arrow B, the air flows past the and outsideheat exchange tubes 112 and the vapour refrigerant flowing inside theheat exchange tubes 112 is condensed. The condensed refrigerant egressing the first core defining thecondensing section 110 is collected by thefirst outlet collector 150b. Thefirst outlet collector 150b includes afirst outlet 152b configured thereon and in fluid communication therewith. The condensed refrigerant, including some refrigerant vapours, debris and incompressible moisture, if any egresses through thefirst outlet 152b and enters theinlet 130a to the receiver drier 130 as depicted by the arrow C. More specifically, thefirst outlet 152b is connected to theinlet 130a to the receiver drier 130 via the firstflexible conduit 172a and the condensed refrigerant, along with some incompressible moisture, debris and uncondensed refrigerant vapours, if any flows from thefirst outlet 152b to theinlet 130a to the receiver drier 130 as depicted by arrow C. Thereafter, the condensed refrigerant along with some incompressible moisture and uncondensed refrigerant vapours flows through the receiver drier 130 in flow direction depicted by arrow D and incompressible moisture and debris are removed from the condensed refrigerant as it flows through the receiver drier 130. The condensed refrigerant with moisture and debris removed therefrom egresses the receiver drier 130 and enters thesub cooling section 120 by flowing along flow direction depicted by arrow E. More specifically, thesecond inlet collector 160a includes asecond inlet 162a formed thereon and in fluid communication therewith and a second connecting line in form of a secondflexible conduit 172b connects theoutlet 130b of the receiver drier 130 to thesecond inlet 162a. Thesecond inlet collector 160a distributes the condensed refrigerant with moisture and debris removed therefrom to thesub-cooling section 120. In thesub-cooling section 120, the condensed refrigerant is sub cooled. The sub-cooled refrigerant is collected in thesecond outlet collector 160b. The sub cooled refrigerant collected in thesecond outlet collector 160b egresses through asecond outlet 162b of thesecond outlet collector 160b. In accordance with an embodiment of the present invention, the first and the second connecting lines between the receiver drier 130 and thefirst outlet 152b formed on thefirst outlet collector 150b and thesecond inlet 162a formed on thesecond inlet collector 160a can be incorporated into at least one of thefirst outlet collector 150b, thesecond inlet collector 160a, and the receiver drier 130. Specifically, the first and the second connecting lines may be formed as inner channels or side channels, for example formed on walls of at least one offirst outlet collector 150b, thesecond inlet collector 160a and the receiver drier 130. More specifically, the first and the second connecting lines may be coextruded on walls of at least one of thefirst outlet collector 150b, thesecond inlet collector 160a and the receiver drier 130.In accordance with another embodiment, the receiver drier 130 can be disposed either in front or behind the first and the second cores defining thecondensing section 110 and thesub-cooling section 120 respectively. - Also, in accordance with another embodiment of the present invention, the receiver drier 130 can be disposed along and adjacent to the longitudinal side of at least one of the first and the second cores defining the
condensing section 110 and thesub-cooling section 120 respectively. -
