Description

[0002] Existing thermal management systems typically include multiple independent components such as heat exchangers and expansion tanks. The heat exchanger exchanges heat or cold from the refrigerant circuit with the coolant in the expansion tank, and then the coolant transfers the heat or cold to the target object, thus achieving thermal management. However, separately installing heat exchangers and expansion tanks makes the system complex, has low integration, occupies a large installation space, and is costly. Furthermore, the temperature field distribution of existing heat exchangers often exhibits temperature fluctuations and repetitive processes, leading to low efficiency.

Furthermore, by embedding the heat exchanger core assembly within a shell (also called a kettle) containing the heat exchange fluid, and configuring the heat exchanger core assembly so that the heat exchange fluid sequentially passes through the second heat exchange plate and the first heat exchange plate for heat exchange, the temperature of the heat exchange fluid can gradually rise, improving heat exchange efficiency.

[0026] The following specific embodiments illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification.

[0027] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art in understanding and reading the content disclosed herein, and are not intended to limit the implementation conditions of this disclosure. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effectiveness and purpose of this disclosure, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "above" and "a" used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this disclosure's implementation.

[0028] This disclosure provides a submersible heat exchanger core assembly, which can exchange heat with a directionally flowing heat exchange fluid (e.g., coolant). Specific embodiments of this disclosure are described below with reference to the accompanying drawings. It should be noted that the arrows in the drawings indicate the flow direction of the heat exchange fluid.

[0029] Please see Figure 1 The heat exchanger core assembly 1 includes a first heat exchange plate 10 and a second heat exchange plate 20, wherein the first heat exchange plate 10 and the second heat exchange plate 20 are in fluid communication, and the first heat exchange plate 10 and the second heat exchange plate 20 are aligned along the flow direction of the heat exchange liquid (e.g., ...). Figure 1 (As indicated by the arrow in the image) are stacked so that the heat exchange liquid can pass through the second heat exchange plate 20 and the first heat exchange plate 10 in sequence and exchange heat with the two heat exchange plates.

[0030] Please see Figure 2 and Figure 6 The first heat exchange plate 10 may be provided with a first partition 11, which divides the first heat exchange plate 10 into a first upper region 12 and a first lower region 13. The fluid (e.g., refrigerant) flowing into the first heat exchange plate 10 will first flow through the first upper region 12, and then flow through the first lower region 13 and leave the first heat exchange plate 10.

[0031] Specifically, the first heat exchange plate 10 includes multiple parallel first heat exchange tubes 100 and first manifolds 101 and second manifolds 102 respectively disposed at both ends of the multiple first heat exchange tubes 100. A gap is spaced between any two adjacent first heat exchange tubes 100, meaning the multiple parallel first heat exchange tubes 100 are arranged at intervals, allowing the heat exchange fluid to pass through the first heat exchange plate 10 and exchange heat with the fluid in each first heat exchange tube 100 to the greatest extent possible. The first manifolds 101 are in fluid communication with the multiple first heat exchange tubes 100 and are located on the first side of the heat exchanger core assembly 1 (e.g., ...). Figure 2(as shown on the right); the second manifold 102 is in fluid communication with the plurality of first heat exchange tubes 100 and is located on the second side of the heat exchanger core assembly 1 (as shown on the right); Figure 2 (As shown on the left), the first side and the second side are arranged opposite each other.

[0032] The first baffle 11 is disposed in the first manifold 101 and divides the first manifold 101 into a first upper manifold region 1011 and a first lower manifold region 1012. The fluid in the first upper manifold region 1011 is blocked by the first baffle 11 and cannot directly enter the first lower manifold region 1012. This arrangement causes the fluid entering the first upper manifold region 1011 to first flow through each of the first heat exchange tubes 100 in the first upper region 12 and reach the part of the second manifold 102 corresponding to the first upper region 12. Since no baffle is disposed in the second manifold 102, the fluid reaching the second manifold 102 will move downward and flow through each of the first heat exchange tubes 100 in the first lower region 13 to the first lower manifold 1012.

[0033] Please see Figure 3 , Figure 7 and Figure 8 The second heat exchange plate 10 may have a second partition 21 inside, which divides the second heat exchange plate 20 into a second upper region 22 and a second lower region 23. In one embodiment, as... Figure 2 and Figure 3 As shown, a connecting path 33 can be provided between the second upper region 22 of the second heat exchange plate 20 and the first lower region 13 of the first heat exchange plate 10, so that the fluid entering the heat exchanger core assembly 1 can flow sequentially through the first upper region 12, the first lower region 13, the second upper region 22, and the second lower region 23, and then flow out of the heat exchanger core assembly 1. That is, the fluid entering the heat exchanger core assembly 1 will first flow through the first heat exchange plate 10, then through the second heat exchange plate 20, and then flow out of the heat exchanger core assembly 1. This arrangement can make the temperature field distribution of the heat exchanger core assembly 1 change layer by layer (e.g., increase or decrease layer by layer), improve the heat exchange efficiency, and avoid the problem of low heat exchange efficiency caused by temperature fluctuations and repeated processes in the temperature field distribution.

[0034] Specifically, the second heat exchange plate 20 includes multiple parallel second heat exchange tubes 200 and third manifolds 201 and fourth manifolds 202 respectively disposed at both ends of the multiple second heat exchange tubes 200. A gap is spaced between any two adjacent second heat exchange tubes 200, meaning the multiple parallel second heat exchange tubes 200 are arranged at intervals, allowing the heat exchange fluid to pass through the second heat exchange plate 20 and exchange heat with the fluid in each second heat exchange tube 200 to the maximum extent. The third manifolds 201 are in fluid communication with the multiple second heat exchange tubes 200 and are located on the first side of the heat exchanger core assembly 1 (e.g., ...). Figure 3(as shown on the right); the fourth manifold 202 is in fluid communication with the plurality of second heat exchange tubes 200 and is located on the second side of the heat exchanger core assembly 1 (as shown on the right); Figure 3 (As shown on the left).

[0035] The second baffle 21 can be disposed in the third manifold 201, dividing the third manifold 201 into a third upper manifold region 2011 and a third lower manifold region 2012. This prevents the fluid in the third upper manifold region 2011 from directly entering the third lower manifold region 2012 due to the second baffle 21. This arrangement causes the fluid entering the third upper manifold region 2011 to first flow through each of the second heat exchange tubes 200 in the second upper region 22 and reach the portion of the fourth manifold 202 corresponding to the second upper region 22. The third upper manifold region 2011 can be fluidly connected to the first lower manifold region 1012 via the connecting path 33 (i.e., the connecting path 33 connects the third upper manifold region 2011 and the first lower manifold region 1012), so that the fluid in the heat exchanger core assembly 1 can flow to the second heat exchange plate 20 after flowing through the first heat exchange plate 10, and especially to the third upper manifold region 2011.

[0036] In one embodiment, the second baffle 21 is only provided in the third manifold 201 (i.e., no baffle is provided in the fourth manifold 202). In this case, the heat exchanger core assembly 1 can be used as an evaporator (not shown). Since no baffle is provided in the fourth manifold 202, the fluid that reaches the fourth manifold 102 will flow downward and flow through each of the second heat exchange tubes 200 in the second lower region 23 to the third lower manifold 2012, and finally flow out of the second heat exchange plate 20.

[0037] In this embodiment, the second baffle 21 is not only disposed in the third manifold 201, but also in the fourth manifold 202. That is, the second heat exchange plate 20 in this embodiment is provided with two second baffles 21. The second baffle 21 in the fourth manifold 202 can divide the fourth manifold 202 into a fourth upper manifold region 2021 and a fourth lower manifold region 2022, so that the fluid in the fourth upper manifold region 2021 is blocked by the second baffle 21 and cannot directly enter the fourth lower manifold region 2022.

[0038] To enable fluid communication between the fourth upper manifold zone 2021 and the fourth lower manifold zone 2022 (i.e., to enable fluid communication between the second upper zone 22 and the second lower zone 23), the heat exchanger core assembly 1 may further include a gas-liquid separator 40. This gas-liquid separator 40 is disposed between the second upper zone 22 and the second lower zone 23 of the second heat exchange plate 20, enabling fluid communication between the second upper zone 22 and the second lower zone 23. In this case, the heat exchanger core assembly 1 can function as a condenser (e.g.,...). Figure 1-3 (As shown).

[0039] For details, please continue to see Figure 3 and Figure 8The gas-liquid separator 40 may include a separator inlet 41 and a separator outlet 42, wherein the separator inlet 41 is fluidly connected to the fourth upper manifold zone 2021, and the separator outlet 42 is fluidly connected to the fourth lower manifold zone 2022 (that is, the gas-liquid separator 40 is connected between the fourth upper manifold zone 2021 and the fourth lower manifold zone 2022). This arrangement allows the fluid entering the third upper manifold zone 2011 to first flow through each of the second heat exchange tubes 200 in the second upper zone 22 to reach the fourth upper manifold zone 2021, and then enter the gas-liquid separator 40 through the separator inlet 41 for gas-liquid separation. The gas-liquid separated fluid (i.e., liquid fluid) then flows out of the gas-liquid separator 40 through the separator outlet 42 and enters the fourth lower manifold zone 2022, and then flows through each of the second heat exchange tubes 200 in the second lower zone 23 to reach the third lower manifold zone 2012, and then flows out of the second heat exchange plate 20.

[0040] As can be seen, the second partition 21 divides the second heat exchange plate 20 into a second upper region 22 and a second lower region 23, and the gas-liquid separator 40 is disposed between the second upper region 22 and the second lower region 23. This makes the second lower region 23, which is downstream of the gas-liquid separator 40, a subcooled region, and the second upper region 21, the first upper region 11, and the first lower region 12, which are upstream of the gas-liquid separator 40, are all condensation regions. The fluid (e.g., refrigerant) in the heat exchanger core assembly 1 can increase the subcooling degree of the refrigerant when it flows through the subcooled region.

[0041] Please refer to the above. Figures 1 to 5 The heat exchanger core assembly 1 may further include an end plate 30 located on its first side. The end plate 30 may be generally plate-shaped and fixed (e.g., welded) to the first manifold 101 and the third manifold 201. The end plate 30 may be provided with a fluid inlet 31, a fluid outlet 32, and the aforementioned communication path 33, wherein the fluid inlet 31 is in fluid communication with the first upper manifold section 1011 (e.g., Figure 2 As shown), fluid can flow into the first upper manifold section 1011 of the heat exchanger core assembly 1 via fluid inlet 31; fluid outlet 32 ​​is in fluid communication with the third lower manifold section 2012 (as shown). Figure 3 (as shown), allowing the fluid in the heat exchanger core assembly 1 to flow out through the fluid outlet 32; one end of the connecting path 33 is fluidly connected to the first lower manifold section 1012 (as shown). Figure 2 As shown), and its other end is fluidly connected to the third upper manifold area 2011 (as shown). Figure 3 As shown), the first heat exchange plate 10 is fluidly connected to the second heat exchange plate 20.

[0042] In this embodiment, the flow path 33 is configured as a groove on the end plate 30, such as... Figure 5As shown, when fixing the end plate 30 to the heat exchanger core assembly 1, the middle portion of the groove can be blocked / sealed by the outer walls (e.g., the planar outer walls) of the first liquid collecting pipe 101 and the third liquid collecting pipe 201 to form a flow channel, and the two ends of the groove are respectively connected to the first lower manifold area 1012 and the third upper manifold area 2011. This arrangement facilitates manufacturing and improves the tolerance of installation error. Of course, this disclosure is not limited to this. For example, the flow path 33 can also be a flow channel in the end plate 30, and only the openings at both ends of the flow channel are exposed on the side of the end plate 30 near the heat exchanger core assembly 1, as long as the connection path 33 can fluidly connect the first lower manifold area 1012 and the third upper manifold area 2011.

[0043] The following will combine Figures 2 to 3 This section mainly explains the flow path and temperature changes of the fluid in heat exchanger core assembly 1.

[0044] First, a high-temperature, high-pressure fluid (such as refrigerant) flows into the heat exchanger core assembly 1 through the fluid inlet 31, then flows through the first upper manifold region 1011 into each of the first heat exchange tubes 100 in the first upper region 12, and reaches the second manifold 102. Since there is no baffle in the second manifold 102, the fluid in the second manifold 102 can flow downwards and through each of the first heat exchange tubes 100 in the first lower region 13 to the first lower manifold region 1012, and then flows through the flow path 33 into the third... The fluid flows from the upper manifold zone 2011, through the second heat exchange tubes 200 in the second upper zone 22, to the fourth upper manifold zone 2021. In the fourth upper manifold zone 2021, the fluid enters the gas-liquid separator 40 through the separator inlet 41 for gas-liquid separation. The liquid fluid flows through the separator outlet 42 to the fourth lower manifold zone 2022, and then through the second heat exchange tubes 200 in the second lower zone 23 to the third lower manifold zone 2012. Finally, it flows out of the heat exchanger core assembly 1 through the fluid outlet 32. Thus, the fluid flowing into the heat exchanger core assembly 1 sequentially passes through the first upper zone 12 and the first lower zone 13 of the first heat exchange plate 10, the second upper zone 22 and the second lower zone 23 of the second heat exchange plate 20, and then flows out of the heat exchanger core assembly 1.

[0045] As high-temperature, high-pressure fluids (such as refrigerant) flow within the heat exchanger core assembly 1, they exchange heat with the external heat exchange fluid. Therefore, the temperature and pressure of the refrigerant gradually decrease as it flows through the heat exchanger core assembly 1. In other words, the temperature of the second heat exchange plate 20 is lower than that of the first heat exchange plate 10, resulting in a layer-by-layer temperature field distribution in the heat exchanger core assembly 1 (e.g., increasing or decreasing layer by layer). Thus, when the external heat exchange fluid (such as coolant) passes through the heat exchanger core assembly 1 and exchanges heat with it, it first contacts the lower-temperature second heat exchange plate 20 and exchanges heat, and then contacts the higher-temperature first heat exchange plate 10. This causes the temperature of the heat exchange fluid to gradually rise, improving heat exchange efficiency and avoiding the problem of reduced heat exchange efficiency caused by the fluctuating and repetitive temperature field distribution of the heat exchanger core assembly 1.

[0046] It should be noted that the above-mentioned fluid flow path and temperature change are the case when the heat exchanger core assembly 1 is used as a condenser; when the heat exchanger core assembly 1 is used as an evaporator, the temperature change is exactly the opposite, but the flow path is roughly similar. The only difference is that the fluid flowing to the upper part of the fourth manifold 102 flows directly downward to the lower part and then enters each of the second heat exchange tubes 200 in the second lower section 23, instead of flowing into the lower part of the fourth manifold 102 and then into each of the second heat exchange tubes 200 in the second lower section 23 after passing through the gas-liquid separator 40. This is something that those skilled in the art can understand, so it will not be described in detail here.

[0047] Although the above embodiments of this disclosure are illustrated by taking the fluid inlet 31, fluid outlet 32, and connecting path 33 as examples of being located on the end plate 30, this disclosure is not limited thereto. For example, the fluid inlet 31 can also be directly located in the first upper manifold area 1011; the fluid outlet 33 can also be directly located in the third lower manifold area 2012; and the connecting path 33 can be configured as an independent flow channel, as long as the fluid inlet 31 is fluidly connected to the first upper manifold area 1011, the fluid outlet 33 is fluidly connected to the third lower manifold area 2012, and the connecting path 33 is connected between the first lower manifold area 1012 and the third upper manifold area 2011.

[0048] The above embodiments of this disclosure are mainly illustrated by the example of the fluid in the heat exchanger core assembly 1 flowing sequentially through the first upper region 12, the first lower region 13, the second upper region 22, and the second lower region 23. However, this disclosure is not limited to this. For example, the number and position of the baffles in the heat exchanger assembly 1 can be adjusted, and flow channels can be designed to change the flow path of the fluid.

[0049] Furthermore, the above embodiments of this disclosure are mainly described using the heat exchanger core assembly 1 as a condenser as an example. However, this disclosure is not limited to this. For example, the heat exchanger core assembly 1 can also be used as an evaporator. In this case, the heat exchanger core assembly 1 does not have a gas-liquid separator 40, and the second baffle 22 in the fourth manifold 202 can be omitted.

[0050] The heat exchanger core assembly provided in this disclosure is configured to exchange heat with a directionally flowing heat exchange liquid. The heat exchanger core assembly includes a first heat exchange plate and a second heat exchange plate that are fluidly connected and stacked. By designing the flow path of the fluid within the heat exchanger core assembly, the temperature field distribution of the heat exchanger core assembly can be made to change layer by layer (e.g., increase or decrease layer by layer), thereby improving the heat exchange efficiency and avoiding the problem of low heat exchange efficiency caused by temperature fluctuations and repeated processes in the temperature field distribution.

[0051] This application also provides an integrated kettle 2, which includes a housing H and the aforementioned heat exchanger core assembly 1. The housing H contains a directionally flowing heat exchange liquid (e.g., coolant, but this disclosure is not limited thereto). The heat exchanger core assembly 1 is disposed within the housing H, and the heat exchange fluid within the housing H can flow directionally through the heat exchanger core assembly 1 and exchange heat with it. Specifically, as... Figure 9 As shown, the housing H of the integrated kettle 2 has an inlet 3 and an outlet 4. The heat exchange fluid can enter the housing H from the inlet 3 and can be directed from one side of the heat exchanger core assembly 1 (e.g., Figure 9 The water flows sequentially through the second heat exchange plate 20 and the first heat exchange plate 10 of the heat exchanger core assembly 1 (on the left side of the image) and flows to the other side of the heat exchanger core assembly 1 (e.g., the left side of the image). Figure 9 (on the right side of the middle), and finally flow out of the casing H from outlet 4 (as shown in the image). Figure 9 (As indicated by the arrow in the image) to complete the heat exchange between the heat exchange fluid and the heat exchanger core assembly 1.

[0052] This disclosure integrates a heat exchanger core assembly into a housing (also known as a kettle) containing heat exchange fluid, and configures the heat exchanger core assembly so that the heat exchange fluid passes sequentially through a second heat exchange plate and a first heat exchange plate for heat exchange. This allows the temperature of the heat exchange fluid to gradually rise, improving heat exchange efficiency. At the same time, the above configuration simplifies the structure, improves integration, and effectively saves installation space.

[0053] The foregoing description of exemplary embodiments of the heat exchanger core assembly and integrated kettle provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
