Description

heat exchanger assembly

This disclosure relates to heat exchanger assemblies. Specifically, the present invention refers to a heat exchanger assembly for an automobile.

A conventional air conditioning system includes a condenser, evaporator, expansion device, compressor, and heater. Conventional condensers generally include a condenser section and a subcooler section, and in particular single heat exchangers include a condenser section and a subcooler section.

Conventional air conditioning systems also include a receiver drier, which may be placed between the condenser and the expansion valve within the air conditioning loop. The receiver dryer is arranged along the outlet side of the condenser, in particular along the length of the outlet collector of a pair of manifolds of the condenser. The receiver dryer comprises a tubular casing or bottle in the form of an airtight container having an inlet and an outlet. The inlet of the receiver dryer receives liquid refrigerant along with some non-condensable refrigerant, dust and incompressible moisture (if present) from a first passageway defining the condensing section of the condenser through a first portion of the outlet manifold. The outlet of the receiver dryer bottle delivers condensed liquid refrigerant free of incompressible moisture and dust through a second section of the outlet manifold to a second passage defining the subcooled section of the condenser. However, there are various drawbacks associated with condensers of this conventional configuration. In particular, conventional condensers, which have condensing and subcooling sections inside and receiver dryers arranged along the manifold, are bulky. Conventional condensers, which consist of condensing and subcooling sections inside and a receiver dryer arranged along the manifold, face packaging problems due to the limited space at the front of the vehicle, and when the vehicle is an electric vehicle (the front part of the electric vehicle is for example cargo Packaging issues are further exacerbated when the condenser contains two separate cores (utilized for equal space utilization) or are placed in a coplanar, non-overlapping configuration to achieve better heat exchange.

In order to overcome packaging problems, a heat exchanger assembly (1) is constructed by assembling separate heat exchangers, for example a first heat exchanger, in particular a condenser (2), and a second heat exchanger, in particular a subcooler (4). ) is already known. Condenser 2 and subcooler 4 may be arranged in a side-by-side or overlapping configuration as depicted in Figure 1. In addition, the receiver dryer 6 is arranged parallel to the heat exchange tubes of the first heat exchanger serving as the condenser 2 and the second heat exchanger serving as the subcooler 4, and the condenser 2 and the subcooler ( 4) Constructs fluid communication between. The refrigerant flows into the first inlet manifold (2a) through the first inlet (3a) and is distributed to the heat exchange tubes of the condenser (2) by the first inlet manifold (2a). The refrigerant after exiting the heat exchange tube of the condenser (2) is the condensed refrigerant that collects in the first outlet manifold (2b), and the condensed refrigerant also contains some non-condensable refrigerant, dust and incompressible moisture (if present). do. The condensed refrigerant, which collects in the first outlet manifold (2b) together with the non-condensable refrigerant, dust and incompressible moisture, is discharged by the first outlet (3b) and through the fluid line (7a) to the first outlet manifold (2b). It is delivered to the inlet (6a) of the receiver dryer (6). Dust and moisture in the condensed refrigerant are removed by a filter and a desiccant bag each maintained within the receiver dryer. The condensed refrigerant from which moisture and dust have been removed, formed by the receiver dryer 6, leaves the receiver dryer 6 through the receiver dryer outlet 6b and through the second inlet 5a and the fluid line 7b. It is transmitted to the second inlet manifold (4a) of the second heat exchanger (4). The second inlet manifold (4a) distributes the condensed refrigerant for subcooling to the heat exchange tubes of the second heat exchanger (4), and the supercooled refrigerant collected by the second outlet manifold (4b) flows to the second outlet ( It leaves the second outlet manifold (4b) via 5b).

However, this arrangement of separate heat exchangers 2, 4 for condensation and subcooling of the refrigerant, interconnected by a receiver dryer 6, involves challenges/drawbacks. More specifically, fluid line 7a is needed to establish fluid communication between the first outlet 3b to the first outlet manifold 2b and the inlet 6a to the receiver dryer 6. Likewise, fluid line 7b is needed to establish fluid communication between the outlet 6b of the receiver dryer 6 and the second inlet 5a to the second inlet manifold 4a. The fluid lines 7a, 7b cause a pressure drop due to loss of fluid flow, thus reducing the efficiency and performance of the receiver dryer 6 and subcooler 4. Additionally, a fluid for establishing fluid communication between the first outlet manifold (2b) for the first heat exchanger (2), the receiver dryer (6) and the second inlet manifold (4a) for the second heat exchanger (4). The use of lines 7a, 7b is complicated and the heat exchanger assembly 1 is difficult to assemble and requires more assembly time. Additionally, conventional heat exchanger assemblies consisting of fluid lines 7a and 7b are bulky and involve packaging issues. Additionally, fluid lines 7a, 7b may interfere with the operation of adjacent elements. Additionally, conventional heat exchanger assemblies require separate, dedicated mounting components to securely mount the receiver dryer. Additionally, the conventional heat exchanger assembly consisting of fluid lines 7a, 7b includes more connections, more elements, especially more connection elements, and therefore the heat exchanger assembly is less reliable and requires more maintenance and maintenance. Includes maintenance costs.

Accordingly, what is needed is a heat exchanger assembly that not only establishes fluid communication between a first outlet manifold for a first heat exchanger, a receiver dryer, and a second inlet manifold for a second heat exchanger, but also provides a stable mounting structure for the receiver dryer. . Additionally, to solve the packing problem, a compact, simple and convenient heat exchanger assembly is needed. Additionally, there is a need for a heat exchanger assembly that includes fewer parts and connections and therefore is relatively more reliable and requires less maintenance than conventional heat exchanger assemblies that include fluid lines.

One object of the present invention is to provide a heat exchanger assembly having a connection system that eliminates the drawbacks associated with conventional heat exchanger assemblies that require fluid lines/fluid conduits for connection between first and second heat exchangers through a receiver dryer. will be.

Assembly 200 includes at least one first heat exchanger 10a and at least one second heat exchanger 10b, a receiver dryer bottle 50 (also simply referred to as “the bottle”), and a bottle 50. It includes a connection system 100 configured to provide fluid communication between the first heat exchanger 10a and the second heat exchanger 10b.

In one example, the first heat exchanger is condenser 10a. The condenser 10a is in fluid communication with the first manifold pair 12a, 14a, in particular the first inlet and outlet manifolds 12a, 14a, respectively, and is in fluid communication with each other via a plurality of heat exchange tubes 16a disposed therebetween. It includes a first inlet manifold (12a) and a first outlet manifold (14a) in communication.

The first inlet manifold 12a distributes the vapor refrigerant contained therein to the heat exchange tube 16a. The vapor refrigerant is condensed into liquid refrigerant by releasing heat to the outside air as the vapor refrigerant flows from the first inlet manifold 12a to the first outlet manifold 14a through the heat exchange tube 16a. The condensed liquid refrigerant that reaches the first outlet manifold 14a also contains some non-condensed refrigerant, dust and moisture (if present). Dust and moisture, if not removed, can damage other elements disposed downstream of the condenser 10a in the air conditioning loop of which the condenser 10a is a part. The condensed liquid refrigerant, along with the non-condensed refrigerant, dust and moisture (if present) pass through bottle 50 for removal of the dust and moisture. More specifically, as the condensed liquid refrigerant passes through the bottle 50 along with the non-condensed refrigerant, dust and moisture, the dust and moisture are removed by a filter and a desiccant bag each maintained inside the bottle 50.

According to one embodiment of the present invention, the bottle 50 includes an inlet 51a and an outlet 51b formed on the same side of the bottle 50, as shown in FIG. 9.

The second opening transfers the fluid, particularly the condensed refrigerant, from which dust and moisture have been removed in the bottle 50, to the second heat exchanger 10b, particularly the subcooler 10b, through the connection system 100. More specifically, the connection block 20 may include an intermediate portion 20c located between the first opening 22a and the second opening 22b. The middle portion 20c may include a delivery plug 30a and a collection plug 30b. The delivery plug 30a may form fluid communication between the first opening 22a and the bottle 50 and the collection plug 30b may form fluid communication between the bottle 50 and the second opening 22b. Thus, fluid communication between the first opening 22a and the second opening 22b is provided through the bottle 50.

The condensed refrigerant after moisture and dust are removed by the desiccant bag and filter respectively disposed in the bottle 50 leaves the bottle 50 and passes through at least a portion of the connection system 100 to the second inlet 18b. 2 is transmitted to the second inlet manifold (12b) of the heat exchanger (10b). The second inlet manifold 12b may be configured to distribute the condensed refrigerant, which is substantially free of dust and moisture, to the second heat exchanger 10b, particularly the heat exchange tube 16b of the subcooler 10b, thereby subcooling it and The supercooled refrigerant is collected in the second outlet manifold (14b). The supercooled refrigerant leaves the second outlet manifold 14b through the second outlet. The supercooler 10b may further include a second mounting bracket 13b for mounting the supercooler 10b on the vehicle frame. Second mounting brackets 13b may be formed on the second inlet and outlet manifolds 12b and 14b, respectively, on opposite sides of the subcooler 10b to provide mounting of the subcooler 10b to the vehicle frame. there is.

The condensed refrigerant received by the first opening 22a includes dust, moisture and some non-condensed refrigerant (if present). In particular, the second end 19b of the jumper line 19, which is connected to the first opening 22a via the second connection element 15b, constitutes fluid communication between the condenser 10a and the connection system 100. . A delivery plug 30a formed on the middle portion 20c forms fluid communication between the first opening 22a and the bottle 50. A collection plug 30b formed on the middle portion 20c forms fluid communication between the bottle 50 and the second opening 22b. With this configuration, fluid communication is provided between the first opening 22a and the second opening 22b through the bottle 50. Delivery plug 30a and collection plug 30b may be configured to provide an airtight or sealing connection with bottle 50. More specifically, the delivery plug 30a may include at least one first rib 32a formed thereon. The first rib 32a is configured to receive a first sealing element therein together with at least one of the first side walls 34a extending radially from the delivery plug 30a and the other adjacent first rib 32a. 1 A channel 36a is formed to form a sealing connection between the bottle 50 and the connection block 20. Likewise, the collection plug 30b may include at least one second rib 32b formed thereon. The second rib 32b is configured to receive a second sealing element therein together with at least one of the second side walls 34b extending radially from the collection plug 30b and the other adjacent second rib 32b. Two channels (36b) are formed to form a sealing connection between the bottle (50) and the connection block (20). The first and/or second sealing element is a deformable O-ring configured to seal the gap between the inlet 51a and outlet 51b of the bottle 50 and each plug 30a, 30b. ) can be provided.

Preferably, the first part 20a, the second part 20b and the middle part 20c of the connection system 100 can be formed integrally with each other. More specifically, the first part 20a, the second part 20b and the middle part may be made of aluminum material and formed by a single step molding process. A connecting block 20 of aluminum material is soldered to the second inlet manifold 12b. In general, the first part 20a, the second part 20b and the middle part 20c are made from one piece. In another embodiment, connection system 100 is of modular construction, wherein first portion 20a, second portion 20b, and middle portion 20c are separated from each other and assembled together to form connection system 100. constitutes. In a preferred embodiment, the first part 20a and the second part 20b are orthogonal to each other. In other embodiments, the first portion 20a and the second portion 20b may be positioned at any angular orientation relative to each other based on packaging constraints or to solve packaging problems. However, as long as the connection system 100 can establish fluid communication between the condenser 10a and the subcooler 10b through the bottle 50, the present invention provides a modular or integrated structure of the connection system 100, Limitations on the number, configuration and orientation of the first and second portions, on the number, arrangement and orientation of the first and second openings 22a, 22b, and on the number, configuration and orientation of the delivery plug 30a and collection plug 30b. It doesn't work.

The connection block 20 may further include a mounting member 40 for mounting the bottle 50 on the connection block 20 . The mounting structure 40 includes an essentially C-shaped portion configured to facilitate securing the bottle 50 to the connection block 20 . The mounting structure 40 may include at least one hole 42 and a corresponding bolt 44 formed on the connecting block 20 .

With this configuration, the connection block 20 not only establishes fluid communication between the condenser 10a and the subcooler 10b through the bottle 50, but also provides stable mounting of the bottle 50 thereon.

The connection system 100 of this configuration eliminates the fluid line required to establish fluid communication between the condenser 10a and the subcooler 10b through the receiver dryer bottle 50. Accordingly, the heat exchanger assembly 200 comprised of the connection system 100 of the present invention eliminates disadvantages such as fluid lines and fluid flow losses associated with the use of fluid lines. Additionally, the heat exchanger assembly 200 comprised of the connection system 100 of the present invention provides a clean aesthetic appeal by eliminating fluid lines/conduits for connection between the heat exchanger and the receiver dryer.
