[0002] Generally, a heat exchanger is a device that exchanges heat through the method of heat absorption or heat dissipation between different heat exchange media. Heat exchangers applied to vehicles can be classified into radiators, air-cooled superchargers, condensers, etc., depending on their function and structure. These heat exchangers include automatic transmission fluid heaters, exhaust gas recirculation coolers, and transmission oil coolers, which dissipate or absorb heat through heat exchange with a refrigerant such as coolant. In this case, heat exchangers are classified into water-cooled types, which use coolant—which has a relatively higher specific heat than air—as a refrigerant, and air-cooled types, which use internal or external air.

[0003] Meanwhile, such heat exchangers are equipped with a header assembly for the circulation of a working fluid, such as a heat exchange medium. In the case of such a header assembly, deformation, such as spreading outward, can occur due to the pressure exerted by the working fluid circulating inside.

Specific details for implementing the invention

[0031] Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. However, the concept of the present invention is not limited to such an embodiment, and the concept of the present invention may be proposed differently by adding, changing, or deleting components constituting the embodiment, and such are also included within the concept of the invention.

[0033] Referring to FIGS. 1 and 2, a header assembly (1) of a heat exchanger (R) according to a preferred embodiment of the present invention includes a header plate (10), a header tank (20), and a reinforcing rib (30).

[0034] For reference, the header assembly (1) described in the present invention is mounted on a heat exchanger (R) including a radiator installed in an automobile, building, electronic device, etc., and provides a flow path (F) (see FIG. 3) for a circulating working fluid. Such header assemblies (1) are provided in pairs so as to be coupled to one side and the other side of the heat exchanger (R) so as to face each other, thereby providing a circulation path for the working fluid.

[0035] The header plate (10) is coupled to the heat exchanger (R). In this embodiment, the header plate (10) is exemplified as being coupled to either one side or the other side of the heat exchanger (R) that face each other with the heat exchanger (R) in between. Additionally, as shown in FIG. 1, the header plate (10) is a plate having an area capable of covering one side and the other side of the heat exchanger (R), respectively.

[0036] The header tank (20) is coupled to the header plate (10) to form a flow path (F) for the working fluid. That is, the header tank (20) is coupled to the header plate (10) having a shape that can provide a predetermined space between it and the header plate (10) through which the working fluid can circulate.

[0037] As shown in FIG. 3, the header tank (20) includes a pair of straight regions (21) that extend vertically from the end connected to the header plate (10) with a flow path (F) in between, and a curved region (22) that curvilinearly connects the pair of straight regions (21). Here, the curved region (22) is formed in a semicircular shape and provides a flow path (F) inside.

[0038] The lengths of the straight area (21) and the curved area (22) of the header tank (20) are not limited to the illustrated example and can be changed according to the capacity of the working fluid passing through the flow path (F), the heat exchange capacity of the heat exchanger (R), etc.

[0039] A plurality of reinforcing ribs (30) are provided protruding from the outer surface of the header tank (20) to reinforce the strength of the header tank (20). These reinforcing ribs (30) are provided on the outer surface of the header tank (20) to prevent the header tank (20) from being deformed by internal pressure generated by the working fluid flowing inside the header tank (20). According to the present embodiment, the reinforcing ribs (30) are provided to extend obliquely with respect to the header plate (10), and in this embodiment, include a first rib (31) and a second rib (32).

[0040] For reference, in this embodiment, the reinforcing rib (30) is illustrated and exemplified as including both the first rib (31) and the second rib (32), but a modified example including multiple of only one of the first rib (31) and the second rib (32) is also possible.

[0041] A plurality of first ribs (31) are provided to extend along the perimeter of the header tank (20) in an inclined direction relative to the header plate (10). As illustrated in FIGS. 2 and 3, these first ribs (31) are connected to a pair of straight areas (21) and curved areas (22) of the header tank (20), thereby having a length that spans across the pair of straight areas (21) and curved areas (22). As a result, the first ribs (31) reinforce the strength of the entire area of ​​the header tank (20). Additionally, the first ribs (31) are provided spaced apart from each other in the longitudinal direction of the header tank (20). At this time, the spaced interval between the plurality of first ribs (31) is not limited to the illustrated example, and the number of first ribs (31) is also not limited.

[0042] As shown in FIG. 3, the first rib (31) can be provided with an inclination angle greater than 0 and less than 10° or greater than -10° and less than 0 with respect to the header plate (10). That is, as shown in FIG. 3, if the inclination angle of the first rib (31) with respect to the vertical reference of the header plate (10)—that is, the parallel line (L) parallel to the header plate (10)—is denoted as A1, then 0 <A1≤10˚ 또는 -10˚≤A1<0일 수 있다. 이러한 제1리브(31)의 경사 각도 범위는 일 예이며, 한정 사항은 아니다. 또한, 복수의 제1리브(31)들의 경사 각도는 각각 서로 다르게 마련되는 변형예도 가능하다.

[0043] Multiple second ribs (32) are provided in parallel with each other, with a length shorter than that of multiple first ribs (31). These second ribs (32) are illustrated and exemplified as being provided one at a time between the mutually spaced intervals of multiple first ribs (31), but this is merely an example and not a limitation. That is, variations in which two or more second ribs (32) are provided between the mutually spaced first ribs (31) are possible instead of just one. Additionally, while the lengths of the multiple second ribs (32) are exemplified as being mutually constant, variations in which the lengths of the multiple second ribs (32) are each different are also possible.

[0044] The second rib (32) reinforces the strength of the straight area (21), which is the end of the header tank (20), where expansion may occur outward due to internal pressure caused by the working fluid passing through the flow path (F) inside the header tank (20). That is, the second rib (32) has a length corresponding to the straight area (21) of the header tank (20) and is provided in multiple numbers at an angle to the header plate (10), thereby preventing deformation such as expansion of the header tank (20) caused by the working fluid.

[0045] As shown in FIG. 2, if the inclination angle of the second rib (32) relative to the vertical reference of the header plate (10) is denoted as A2, the inclination angle of the second rib (32) is 0, just like the first rib (31). <A2≤10˚ 또는 -10˚≤A2<0일 수 있다. 이러한 제2리브(32)의 경사 각도 범위는 한정 사항은 아니며, 복수의 제2리브(32)가 각각 서로 다른 경사 각도를 가질 수도 있다.

[0046] For reference, the number of the first rib (31) and the second rib (32) can be varied within a range that does not exceed the total weight of the header assembly (1).

[0047] The first rib (31) and the second rib (32) described above are both injection molded on the outer surface of the header tank (20) by injecting an injection molded product mixed with a reinforcing material through a gate (30a) provided in one of the plurality of first ribs (31). More specifically, the first rib (31) and the second rib (32) are injection molded by injecting an injection molded product mixed with a reinforcing material including glass fiber and a resin material such as polyamide (PA) or polypropylene (PP) through the gate (30a). At this time, the header tank (20) and the reinforcing rib (30) can be injection molded simultaneously as a single unit by the injection molded product mixed with the reinforcing material injected through the gate (30a). For reference, the reinforcing material including glass fiber may be mixed into the injection molded product at a ratio of approximately 20 to 40%, but this is not a limitation.

[0048] A reinforcing rib (30) according to one embodiment of the present invention is exemplified as shown in FIG. 2, in which a gate (30a) is provided at a position corresponding to the centerline (C) with respect to the longitudinal direction of the header tank (20), and an injection product is injected through the gate (30a). The position of the gate (30a) is not limited to the illustrated example, and variations are also possible in which the gate (30a) is provided at a position offset to the left or right with respect to FIG. 2, in which the injection product is injected.

[0049] Meanwhile, in this embodiment, the gate (30a) is provided at the centerline (C) position with respect to the longitudinal direction of the header tank (20), and reinforcing ribs (30) are provided on both sides of the header tank (20) in a symmetrical shape with respect to the centerline (C). More specifically, a plurality of first ribs (31) and second ribs (32) are provided at an angle of inclination toward the centerline (C) of the header tank (20). However, this is not strictly limited thereto, and various modified embodiments are possible, such as the direction of the angle of inclination of the first ribs (31) and second ribs (32) being mutually asymmetric with respect to the centerline (C) of the header tank (20), or the direction of the angle of inclination being alternately switched.

[0050] As the first rib (31) and the second rib (32) are arranged at an angle to the header plate (10), a vortex is generated in the resin flow of the injection molded product, thereby inducing an uneven arrangement direction of reinforcing materials such as glass fibers. The uneven arrangement of reinforcing materials is advantageous for reinforcing rigidity as the reinforcing ribs (30) are injection molded in a structure that is intertwined and tangled. When the arrangement direction of reinforcing materials is induced unevenly, deformation of the header tank (20) can be effectively prevented due to a mismatch with the pressure direction of the working fluid flowing along the flow path (F) inside the header tank (20).

[0051] Referring to FIG. 4, an image illustrating the arrangement direction of reinforcing materials in the header assembly (1) of a heat exchanger (R) is schematically illustrated.

[0052] As shown in FIG. 4(a), in the conventional case where the first rib (31') and the second rib (32') of the reinforcing rib (30') are arranged perpendicularly to the header plate (10), it can be confirmed that the alignment direction of the reinforcing material injected through the gate (30a') is uniform. Additionally, as shown in FIG. 4(b), in the case where the first rib (31) and the second rib (32) are arranged at an angle to the header plate (10) according to the present invention, it can be confirmed that the alignment direction of the reinforcing material of the injection molded product injected through the gate (30a) is non-uniform. For reference, in the image of FIG. 4, the more blue areas there are, the more uniform the alignment direction of the glass fibers is, and the red areas indicate that the alignment direction of the glass fibers is non-uniform.

[0054] Referring to FIG. 5, a header assembly (100) of a heat exchanger (R) according to another embodiment of the present invention is schematically illustrated.

[0055] As shown in FIG. 5, a header assembly (100) of a heat exchanger (R) according to another embodiment includes a header plate (110), a header tank (120), and a reinforcing rib (130). Here, since the configuration of the header plate (110) and the header tank (120) is similar to that of the above-described embodiment, a detailed description is omitted.

[0056] A reinforcing rib (130) according to another embodiment includes a first rib (131), a second rib (132), and a third rib (133). Here, the first rib (131) and the second rib (132) have the same configuration as the embodiment described with reference to FIGS. 1 to 3, so a detailed description is omitted.

[0057] The third rib (133) is provided extending in the longitudinal direction of the header tank (120) so as to face parallel to the header plate (110). This third rib (133) is provided in the straight area (121) among the straight area (121) and curved area (122) of the header tank (120), thereby reinforcing the strength of the straight area (121) of the header tank (120) together with the second rib (132).

[0058] For reference, in other embodiments, a third rib (133) is exemplified as being provided between a straight area (121) and a curved area (122), but the installation position of the third rib (133) can be varied within the straight area (121). The range of height (H) of the third rib (133) spaced from the header plate (110) can be approximately 10 to 25 mm.

[0059] Additionally, in the illustration of FIG. 5, the third rib (133) is provided in a straight shape extending parallel to the header plate (110). These third ribs (133) may be provided in a pair so as to correspond to a pair of straight regions (121) of the header plate (110). However, the shape, number, and thickness of the third rib (133) are not limited to the illustrated example. For instance, various variations are possible in which the third rib (133) has at least one shape among a straight shape parallel to the header plate (110), a wave shape, and an uneven shape with repeating 'V' shapes, and is provided on one side and the other side of the header plate (110). At this time, the number of the third rib (133) can be varied within a range that does not exceed the maximum total weight of the header assembly (100) together with the first rib (131) and the second rib (132).

[0060] As described above, in another embodiment, the header assembly (100) can additionally reinforce the strength of the third rib (133) together with the second rib (132) for the straight area (121) of the header tank (120). As a result, additional strength can be added to the straight area (121) at the bottom of the header tank (120), where expansion may occur due to internal pressure from the working fluid, thereby preventing deformation of the header tank (120).

[0062] As described above, although the present invention has been explained with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the invention as set forth in the following claims.
