Description

heat exchanger assembly

[0001] The present disclosure relates to a heat exchanger assembly, and to a layout structure between a heat exchanger and components communicating with the heat exchanger.

[0002] Global warming and climate change have become serious problems worldwide, and to address these issues, eco-friendly vehicles such as hybrid vehicles, electric vehicles, and hydrogen fuel cell vehicles are being developed.

[0003] These eco-friendly vehicles are equipped with components like batteries and motors, requiring a thermal management system to properly cool and heat these components. A typical example of a thermal management system might be a heat exchanger assembly, including a heat exchanger.

[0004] However, most automotive heat exchanger assemblies are fixed in size, as they must be installed within the limited space within the vehicle. This makes it difficult to control the number of plate layers in the heat exchanger, making it difficult to optimize heat exchanger performance across various environmental factors, such as driving conditions and ambient temperature.

[0010] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0011] The present disclosure relates to a heat exchanger assembly, comprising: a heat exchanger in which a first fluid and a second fluid flow and exchange heat with each other; and a component connected to the heat exchanger and allowing the first fluid to flow therein; wherein the component includes a main body having an open side and a cover plate covering the opening of the main body, and a communication hole is formed in the cover plate, and the first fluid can flow through the heat exchanger and the component by passing through the communication hole.

[0013] When the core is arranged on one side of the cover plate and the number of stacked heat exchange plates is n, n is determined according to the heat exchange capacity required for the core, but can be determined within a range in which the stacked length of n heat exchange plates does not exceed the area of ​​the cover plate.

[0043] Hereinafter, the present disclosure will be described in detail with reference to the attached drawings. However, these are merely exemplary and the present disclosure is not limited to the specific embodiments described as examples.

[0044] A heat exchanger assembly (1000) according to an example of the present disclosure can be applied to vehicles including hybrid electric vehicles, fuel vehicles, and pure electric vehicles, and the fluid heat exchange device can also be applied to other heat exchange fields such as household or industrial applications, and some equipment required for cooling and heating can also be used.

[0045] Hereinafter, a heat exchanger assembly (1000) according to an example of the present disclosure will be described with reference to FIGS. 1 to 3. FIG. 1 is an overall perspective view of a heat exchanger assembly (1000) according to an example of the present disclosure, FIG. 2 is a drawing showing a different direction of FIG. 1, and FIG. 3 is an exploded perspective view of a heat exchanger assembly (1000) according to an example of the present disclosure.

[0046] A heat exchanger assembly (1000) according to an example of the present disclosure may include a heat exchanger (100) in which a first fluid and a second fluid flow and exchange heat with each other, and a component (200) connected to the heat exchanger (100) so that the first fluid can flow therein.

[0047] The component (200) includes a main body (210) with one side open and a cover plate (220) covering the opening of the main body (210), and a communication hole (225) is formed in the cover plate (220), and a first fluid can flow through the heat exchanger (100) and the component (200) by passing through the communication hole (225).

[0048] The heat exchanger (100) may include a core in which a plurality of heat exchange plates are stacked to alternately exchange heat between a first fluid and a second fluid, and the plurality of plates are stacked horizontally, and the heat exchanger may be vertically coupled to one surface of a cover plate. Accordingly, the heat exchanger assembly (1000) may be manufactured in an approximately rectangular parallelepiped shape, and a heat exchanger assembly (1000) that can be efficiently arranged within a limited space layout may be provided.

[0049] Hereinafter, the component (200) will be described in detail. The component (200) is a configuration in which a heat exchange fluid can flow inside, and may be, for example, a reservoir tank, a pump, a valve, a heat exchanger, etc.

[0050] The component (200) may be formed with a plurality of holes or pipes, etc., through which the first fluid may be introduced or discharged, and one of the holes, which is a communication hole (225), is connected to the heat exchanger (100) so that the first fluid may flow through the heat exchanger (100) and the component (200). In the heat exchanger (100), both the first fluid and the second fluid may flow, but in the component (200), only the first fluid, which is one of the fluids flowing through the heat exchanger (100), may flow.

[0051] Specifically, the component (200) may include a main body (210) having an open upper surface and a cover plate (220) that forms a space through which a first fluid can flow and covers the open surface of the main body (210).

[0052] The cover plate (220) has a predetermined area and can be formed to correspond to the edge of the main body (210). Thus, the cover plate (220) can be assembled with the main body (210) on the opening of the main body (210), and the component (200) can be finally sealed.

[0053] Hereinafter, the joint structure of the main body (210) and the cover plate (220) will be described with reference to FIG. 4. A sealing groove (250) may be formed along the edge of the opening surface of the main body (210). Sealant may be applied to the sealing groove (250). This prevents foreign substances such as moisture and dust from entering the internal space of the component through which the first fluid flows.

[0054] In addition, the component (200) may include a pair of coupling holes (230A, 230B) formed so that the main body (210) and the cover plate (220) are bolted together at at least one point. The pair of coupling holes may be formed to protrude outward from the outer peripheral surfaces of the main body and the cover plate, respectively. Bolt grooves may be formed so that bolts can be simultaneously inserted into the pair of coupling holes to fix the main body (210) and the cover plate (220). This can improve the fixing force between the main body and the cover plate.

[0055] Meanwhile, the cover plate (220) may be formed with the aforementioned communication hole (225), and the first fluid can flow through the heat exchanger (100) and the component (200) by passing through the communication hole (225). That is, the cover plate (220) may serve as a kind of cover for sealing the component (200) and at the same time serve as a passage through which the first fluid can flow in and out of the heat exchanger (100) and the component (200).

[0056] Hereinafter, the heat exchanger (100) will be described in detail. In the heat exchanger (100), a first fluid and a second fluid can flow with each other and exchange heat with each other. At this time, the first fluid and the second fluid may be different types of fluids, or may be the same type of fluid but in different states. For example, the first fluid may be a cooling water and the second fluid may be a refrigerant.

[0057] The heat exchanger (100) may correspond to a plate type heat exchanger in which a plurality of plates are stacked and a first fluid and a second fluid alternately flow through the space between the stacked plates to exchange heat with each other.

[0058] According to one example of the present disclosure, a heat exchanger (100) may include a core in which a plurality of heat exchange plates are stacked to alternately exchange heat between a first fluid and a second fluid. In this case, the heat exchanger (100) and the component (200) may be vertically coupled, and the plurality of plates may be stacked horizontally.

[0059] Typically, the number of plate stacks in a plate heat exchanger can be adjusted based on the heat exchange specifications required for the heat exchanger. However, as the number of plate stacks increases, the size of the heat exchanger also increases, which hinders installation in the limited space inside a vehicle. For example, if the plate heat exchanger and components are assembled vertically, and the plate stacking direction of the plate heat exchanger is formed in the same vertical direction as the assembly direction of the heat exchanger and components, the overall height of the heat exchanger assembly will also increase as the number of plate stacks increases.

[0060] According to one example of the present invention, the heat exchanger (100) can be vertically coupled to one side of the cover plate (220), and the assembly direction of the heat exchanger (100) and the component (200) and the stacking direction of the heat exchange plates can be configured differently. This has the advantage of being able to adjust the stacking number of heat exchange plates without increasing the overall size of the heat exchanger assembly, thereby providing optimized heat exchange performance to the system.

[0061] The number of stacked heat exchange plates will be described below with reference to FIG. 5. FIG. 5(a) and 5(b) each illustrate cases where the number of stacked heat exchange plates of the heat exchanger (100) is different from each other.

[0062] The core (110) of the heat exchanger can be arranged on one side of the cover plate (220), and if the number of stacked heat exchange plates is n, n is determined according to the heat exchange capacity required for the core, but can be determined within a range that does not exceed the area of ​​the cover plate (220). (Here, n is a natural number greater than or equal to 2.)

[0063] Looking at the lengths of the plates stacked in FIGS. 5(a) and 5(b), it can be seen that in FIG. 5(a) it is L1, and in FIG. 5(b) it is L2, and it can be seen that L2 is longer than L1. Therefore, if the sizes of each heat exchange plate are the same, it can be seen that the number of stacked heat exchange plates is greater in FIG. 5(b). In this way, by adjusting the number of stacked heat exchange plates, the heat exchange performance of the heat exchanger (100) can be optimized.

[0064] However, the number of stacked heat exchange plates can be determined within a range that does not exceed the area of ​​the cover plate (220). That is, as shown in FIG. 5, the length of the cover plate (220) is L T If so, the length of the stack of n heat exchange plates is L T The value of n can be determined to be smaller. Thus, one example of the present disclosure has the advantage of improving vehicle mountability by maintaining the overall longitudinal size of the heat exchanger assembly even when the number of stacked heat exchanger plates is adjusted.

[0065] Meanwhile, a heat exchanger (100) according to an example of the present disclosure may further include a connecting pipe (150). If, among a plurality of heat exchange plates, a plate positioned on one outer side is referred to as an outermost plate (111), the connecting pipe (150) may be configured to extend from the outermost plate and be inserted into a communication hole. In this case, the first fluid may flow between the heat exchanger (100) and the component (200) through the connecting pipe (150).

[0066] Specifically, the connecting pipe (150) is configured as an L-shaped pipe with a path that is bent once, and the connecting pipe (150) extends horizontally from the outermost plate (111), and then the path is bent so that it can be inserted vertically toward the communication hole (225).

[0067] That is, among the two ends of the connecting pipe (150), the side connected to the heat exchanger (100) may be configured such that the central axis of the pipe is parallel to the stacking direction of the heat exchanger plates, and the part of the two ends of the connecting pipe (150) inserted into the communication hole (225) may be configured such that it is perpendicular to the stacking direction of the heat exchanger plates. This allows the flow resistance of the first fluid to be minimized when entering and exiting the heat exchanger and components. In addition, it is preferable to minimize the length of the connecting pipe (150) in terms of flow resistance, so that the outermost plate (111) may be formed to extend from an area adjacent to the cover plate (220).

[0068] Meanwhile, on one side of the outermost plate (111) on which the connecting pipe (150) is formed, a first pipe (160) through which a first fluid enters and exits the core, a second-first pipe through which a second fluid enters and exits the core, and a second-second pipe that is provided separately from the second-first pipe and through which a second fluid enters and exits the core may be further formed.

[0069] Hereinafter, referring to Fig. 6, the formation locations of the connecting pipe, the first pipe, the second-1 pipe, and the second-2 pipe will be described. As shown in Fig. 6, the outermost plate (111) may be formed in a rectangular shape with a predetermined area, and the area of ​​the outermost plate (111) may be divided into the lower left, lower right, upper left, and upper right.

[0070] If the area of ​​the outermost plate (111) is divided as above, the connecting pipe (150) may be formed in the lower left, and the first pipe (160) may be formed in the upper right, and may be arranged diagonally with respect to each other. In addition, the second-first pipe (170) may be formed in the upper left, and the second-second pipe (180) may be formed in the lower right, and may be arranged diagonally with respect to each other.

[0071] That is, the pipes (150, 160) through which the first fluid enters and exits can be arranged diagonally from each other, and the pipes (170, 180) through which the second fluid enters and exits can be arranged diagonally from each other. By arranging the pipes for entering and exiting each fluid diagonally from each other in this way, the first fluid and the second fluid can flow over a wide area on the heat exchange plate, and the heat exchange efficiency of the heat exchanger can be improved.

[0072] Meanwhile, the first pipe (160), the second-1 pipe (170), and the second-2 pipe (180) can be formed to protrude in the same direction from one surface of the outermost plate (111).

[0073] Furthermore, an inlet pipe (211) through which a first fluid is introduced into the component (200) and an outlet pipe (212) through which the first fluid is discharged outside the component may be formed on one side of the main body (210). The inlet pipe (211) and the outlet pipe (212) may be formed to protrude in the same direction as the protruding direction of the first pipe (160), the second-first pipe (170), and the second-second pipe (180) described above.

[0074] The above-mentioned pipes (160, 170, 180, 211, 212) can be connected to external components (pumps, valves, radiators, compressors, etc.), and the convenience of connection with external components can be improved by forming the pipes so that they all protrude in the same direction.

[0075] In addition, according to one example of the present disclosure, since the heat exchanger (100) and the component (200) can be connected to the external component only on one side, there is no need to provide an additional connection structure (pipe, hose, etc.) on the other side, thereby providing an advantage of improved space efficiency.

[0076] Hereinafter, with reference to FIGS. 7 and 8, a path along which a first fluid flows through a heat exchanger and components according to an example of the present disclosure will be described. FIGS. 7 and 8 are drawings exemplarily showing the flow path of the first fluid.

[0077] The first fluid may be introduced into the inlet pipe (211) as shown in Fig. 7(a), flow through the component (200), and then be directly discharged to the outside through the discharge pipe (212), or may be introduced into the inlet pipe (211) as shown in Fig. 7(b), flow through the component (200), pass through the communication hole (225), flow through the heat exchanger (100), and then be discharged to the outside. In addition, some of the first fluid introduced into the component (200) may be directly discharged to the outside through the discharge pipe (212), and the remaining part may be set to pass through the communication hole (225).

[0078] Additionally, the first fluid may be set to flow through the heat exchanger (100) and then through the component (200) as shown in Fig. 8. That is, the first fluid may be introduced into the first pipe (160), flow through the heat exchanger (100), and then pass through the connecting pipe and the communication hole (225) to be introduced into the component (200). The first fluid may be discharged to the outside through the discharge pipe (212) after flowing through the component.

[0079] As shown in FIGS. 7 and 8, the positions of the inlet pipe (211) and the outlet pipe (212) can be appropriately designed and changed depending on the flow direction of the first fluid.

[0080] In order to control the path of the first fluid as described above, a control valve may be installed at the front end of the inlet pipe (211), the rear end of the discharge pipe (212), and the rear end of the first pipe (160), and the path of the first fluid may be controlled through on / off control and flow rate control of the valve.

[0081] As described above, the heat exchanger assembly according to the present disclosure can satisfy various operating conditions by setting the flow path of the first fluid in various ways, and can provide the advantage of improved flexibility of the system.

[0082] Hereinafter, a method of coupling a heat exchanger (100) and a component (200) according to an example of the present disclosure will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view of a heat exchanger according to an example of the present disclosure, and FIG. 10 is a cross-sectional view of a heat exchanger assembly according to an example of the present disclosure.

[0083] According to one example of the present disclosure, the heat exchanger (100) may further include at least one bracket (130) coupled with the cover plate (220). The bracket (130) may be formed by extending from the plates (111, 112) arranged at the outermost end among the plurality of heat exchange plates.

[0084] The bracket (130) may be configured such that at least a portion of the bracket is in contact with one surface of the cover plate (220), and brazing may be performed in the area where the bracket is in contact with the cover plate (220).

[0085] The surface (131) where the bracket (130) comes into contact with the cover plate (220) may be spaced apart from the bottom of the heat exchange plate by a predetermined distance in the vertical direction. Heat may be generated in the component (200) in some cases, and by configuring the bracket (130) as described above, heat from the component (200) can be prevented from being unnecessarily conducted to the heat exchanger (100).

[0086] Meanwhile, when the bracket (130) is brazed with the cover plate (220), high heat may be generated due to brazing. Therefore, in order to prevent the main body (210) from being damaged by the high heat generated by brazing, it may be desirable to first braze the bracket (130) and the cover plate (220), and then assemble the cover plate (220) by joining it with the main body (210).

[0087] Hereinafter, a vehicle (2000) equipped with a heat exchanger assembly will be described with reference to FIGS. 11 and 12. FIG. 11 illustrates the direction in which the heat exchanger assembly is mounted on the vehicle (2000), and FIG. 12 illustrates the mounting portion of the heat exchanger assembly (1000).

[0088] The main body (210) of the heat exchanger assembly (1000) according to the present disclosure may further include a mounting portion (270) for mounting the heat exchanger assembly on a vehicle. The mounting portion (270) may mount the heat exchanger assembly on a vehicle such that the aforementioned inlet pipe (211) is positioned at the bottom of the vehicle and the discharge pipe (212) is positioned at the top of the vehicle.

[0089] That is, the first fluid flowing through the component (200) can be introduced from the bottom of the component (200) and discharged from the top. This is to prevent air from accumulating in the flow space of the first fluid inside the component (200). If air accumulates in the flow space of the fluid, the flow area becomes narrow, which is a factor that reduces the flow efficiency. Since the air accumulates in the upper part of the flow space, it is almost impossible to discharge the accumulated air to the outside when the fluid is introduced from the upper part. Therefore, in order to remove the air in the flow space, it is preferable to provide a port through which the fluid is discharged in the upper part of the flow space.

[0090] According to the present disclosure, the mounting portion (270) has the advantage of efficiently removing air accumulated in the flow space by mounting the heat exchanger assembly on the vehicle so that the inlet pipe (211) through which the first fluid is introduced is disposed at the bottom of the vehicle and the outlet pipe (212) through which the first fluid is discharged is disposed at the top of the vehicle.

[0091] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
