Abstract
Description
Technical Field
[0001] This application relates to the field of automotive air conditioning parts technology, and in particular to an integrated core for both cooling and heating in automotive air conditioning, an automotive air conditioner, and a vehicle. Background Technology
[0002] Currently, the automotive air conditioning industry is implementing controls, reductions, and even eliminations of HFC refrigerants, and developing green refrigerants. Refrigerant replacement has become a mission of the times. Therefore, based on the industry's demand for environmentally friendly refrigerants, R290 (propane) refrigerant has been highly regarded in the industry.
[0003] like Figure 1 As shown, a secondary heat exchange heat pump system based on R290 is developed to ensure that the R290 refrigerant does not pass through the passenger compartment to ensure the safety of personnel. As a result, the existing air conditioning unit cannot meet the requirements, and the evaporator core a in the existing scheme needs to be cancelled and replaced with the cooling core b.
[0004] However, since the cooling core b and the heating core c in the R290 secondary heat exchange system air conditioning unit are currently designed independently, the size of the cooling core b is larger than that of the conventional system air conditioning unit because the cooling core b needs to increase the heat exchange capacity. This requires more space for the air conditioning unit. Furthermore, this independent structure means that the manufacturer must process both the cooling core b and the heating core c simultaneously during manufacturing, which not only increases labor costs but also increases the input of raw materials.
[0005] Therefore, there is an urgent need to provide an integrated core for both heating and cooling in automotive air conditioning, as well as an automotive air conditioning system and vehicle, to solve the technical problems mentioned above. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this application provides an integrated core for both heating and cooling in automotive air conditioning, an automotive air conditioner, and a vehicle. By integrating the heating core and cooling core into a single core, space can be saved in the air conditioning unit, resulting in a smaller size and lighter weight. This means that when installed in a car, it will not significantly increase the vehicle's weight, thereby reducing energy consumption and saving energy. At the same time, the integrated core also reduces the input of raw materials during processing and manufacturing.

[0048] Example 1
[0049] This embodiment provides an integrated core for both cooling and heating in automotive air conditioning systems. A detailed description follows; please refer to [link / reference]. Figures 2-4As shown, it includes: an upper manifold 1, a lower manifold 2, and a first heat exchange tube 3 and a second heat exchange tube 4 disposed between the upper manifold 1 and the lower manifold 2, the first heat exchange tube 3 and the second heat exchange tube 4 being arranged alternately; wherein, the upper manifold 1, the lower manifold 2 and the first heat exchange tube 3 form a first heat exchange channel, in which a first medium flows, and the first medium is a heat exchange medium or a cooling medium; the upper manifold 1, the lower manifold 2 and the second heat exchange tube 4 form a second heat exchange channel, in which a second medium flows, and the second medium is a heat exchange medium or a cooling medium.
[0050] In this embodiment, a first heat exchange channel is formed between the upper manifold 1, the lower manifold 2, and the first heat exchange tube 3. A first medium flows through this first heat exchange channel, which can be a heat exchange medium or a cooling medium. When the first medium is set as a cooling medium, such as cooling water, the cooling core is achieved through this first heat exchange channel. A second heat exchange channel is formed between the upper manifold 1, the lower manifold 2, and the second heat exchange tube 4. A second medium flows through this second heat exchange channel, which can be a heat exchange medium or a cooling medium. When the second medium is set as a heat exchange medium, such as hot water, the warm air core is achieved through this second heat exchange channel. This design integrates the heating and cooling cores into a single integrated core, saving space in the air conditioning unit and reducing weight. When installed in a car, it does not significantly increase the vehicle's weight, thus reducing energy consumption and saving energy. Furthermore, compared to the traditional independent structure, the integrated core in this embodiment reduces production costs and raw material input during manufacturing, and is easy to install. Additionally, the alternating arrangement of the first heat exchange tube 3 and the second heat exchange tube 4 between the upper manifold 1 and the lower manifold 2 ensures more uniform mixing of hot and cold air.
[0051] Please continue to refer to Figures 2-4 As shown in this embodiment, it should be noted that both the upper manifold 1 and the lower manifold 2 are rectangular. Of course, they are not limited to rectangles; they can also be cylindrical in other embodiments. In this embodiment, only a rectangular shape is used as an example. The upper manifold 1 has a first liquid collection chamber 11 and a second liquid collection chamber 12 with upper and lower layers inside. The lower manifold 2 has a third liquid collection chamber 21 and a fourth liquid collection chamber 22 with upper and lower layers inside. The first liquid collection chamber 11, the first heat exchange tube 3, and the third liquid collection chamber 21 constitute the first heat exchange channel. The second liquid collection chamber 12, the second heat exchange tube 4, and the fourth liquid collection chamber 22 constitute the second heat exchange channel.
[0052] Specifically, both the first heat exchange tube 3 and the second heat exchange tube 4 are configured as flat tubes. However, they are not limited to flat tubes; in other embodiments, they can also be round tubes. This embodiment only uses flat tubes as an example. The upper end (first end) of the first heat exchange tube 3 passes through the second liquid collecting chamber 12 and connects to the first liquid collecting chamber 11. The lower end (second end) of the first heat exchange tube 3 connects to the third liquid collecting chamber 21. Thus, the first liquid collecting chamber 11, the first heat exchange tube 3, and the third liquid collecting chamber 21 constitute the first heat exchange channel. The upper end (first end) of the second heat exchange tube 4 is also connected to the second liquid collecting chamber 12. The lower end (second end) of the second heat exchange tube 4 passes through the third liquid collecting chamber 21 and connects to the fourth liquid collecting chamber 22. Thus, the second liquid collecting chamber 12, the second heat exchange tube 4, and the fourth liquid collecting chamber 22 constitute the second heat exchange channel. Of course, in other embodiments, the connection method of the first heat exchange tube 3 and the second heat exchange tube 4 can be interchanged. This embodiment does not impose specific limitations on how they are connected. In this embodiment, the upper manifold 1 and the lower manifold 2 are arranged in a double layer, so they can be used as the liquid collection pipes of the first heat exchange pipe 3 or the liquid collection pipes of the second heat exchange pipe 4.
[0053] In this embodiment, it should also be noted that the upper manifold 1 or the lower manifold 2 connects the first inlet pipe and the first outlet pipe, and the upper manifold 1 or the lower manifold 2 connects the second inlet pipe and the second outlet pipe. A first partition 13 is provided inside the first liquid collecting chamber 11 or the third liquid collecting chamber 21, which divides the interior of the first liquid collecting chamber 11 or the third liquid collecting chamber 21 into a first inlet chamber 14 and a first outlet chamber 15 for the first medium to enter and exit. In this embodiment, the first partition 13 is set in the first liquid collection chamber 11 as an example. At this time, the first partition 13 divides the first liquid collection chamber 11 into the first liquid inlet chamber 14 on the left and the first liquid outlet chamber 15 on the right. The first inlet pipe is set at one end of the upper manifold 1 and is connected to the first liquid inlet chamber 14. The first outlet pipe is set at the other end of the upper manifold 1 and is connected to the first liquid outlet chamber 15. The upper ends of all the first heat exchange tubes 3 in the first liquid inlet chamber 14 are in a connected state. The upper ends of all the first heat exchange tubes 3 in the first liquid outlet chamber 15 are in a connected state. The lower ends of all the first heat exchange tubes 3 in the third liquid collection chamber 21 are in a connected state. Thus, the first medium enters the first liquid inlet chamber 14 through the first inlet pipe. Within the first liquid inlet chamber 14, the first medium is distributed to several first heat exchange tubes 3, flowing uniformly from the upper end to the lower end, and then all flowing into the third liquid collection chamber 21. In the third liquid collection chamber 21, the first medium flows in the x-direction, and then flows from the lower end to the upper end of the corresponding first heat exchange tube 3, eventually flowing into the first liquid outlet chamber 15 and then out through the first outlet pipe. The first heat exchange channel is arranged in a U-shape. A first baffle 13 is installed in the first liquid collection chamber 11, thereby changing the flow direction of the first medium, resulting in better utilization efficiency, a smaller product structure, and ease of use.
[0054] A second partition 16 is provided inside the second liquid collecting chamber 12 or the fourth liquid collecting chamber 22. The second partition 16 divides the interior of the second liquid collecting chamber 12 or the fourth liquid collecting chamber 22 into a second inlet chamber 17 and a second outlet chamber 18 for the second medium to enter and exit. In this embodiment, the second partition 16 is set inside the second liquid collecting chamber 12 as an example. In this case, the second partition 16 divides the second liquid collecting chamber 12 into a second inlet chamber 17 on the left and a second outlet chamber 18 on the right. The second inlet pipe is set at one end of the upper manifold 1 and is connected to the second inlet chamber 17. The second outlet pipe is set at the other end of the upper manifold 1 and is connected to the second outlet chamber 18. The upper ends of all the second heat exchange tubes 4 in the second inlet chamber 17 are in a connected state. The upper ends of all the second heat exchange tubes 4 in the second outlet chamber 18 are in a connected state. The lower ends of all the second heat exchange tubes 4 in the fourth liquid collecting chamber 22 are in a connected state. Thus, the second medium enters the second inlet chamber 17 through the second inlet pipe. Within the second inlet chamber 17, the second medium is distributed to several second heat exchange tubes 4, flowing uniformly from the upper end to the lower end, and then all flowing into the fourth liquid collection chamber 22. In the fourth liquid collection chamber 22, the second medium flows in the x-direction, then flows from the lower end to the upper end of the corresponding second heat exchange tubes 4, and then all flowing into the second liquid outlet chamber 18, subsequently flowing out through the second outlet pipe. The second heat exchange channel is arranged in a U-shape. A second baffle 16 is installed in the second liquid collection chamber 12, thereby changing the flow direction of the second medium, resulting in better utilization efficiency, a smaller product structure, and ease of use.
[0055] During operation, the integrated core can allow the entry and exit of a first medium, such as cooling water, through the first inlet pipe and the first outlet pipe, and allow the entry and exit of a second medium, such as hot water, through the second inlet pipe and the second outlet pipe, thus achieving uniform flow of the two fluids, cold and hot. When both the first heat exchange tube 3 and the second heat exchange tube 4 are connected to a medium, such as the first medium or the second medium, it can be used interchangeably with the cooling core or heating core in a common air conditioning unit.
[0056] In this embodiment, it should also be noted that a heat conduction structure 5 is provided between the first heat exchange tube 3 and the second heat exchange tube 4 to transfer heat through conduction. The heat conduction structure 5 is a fin, and the fin can be a continuous or discontinuous structure. Regarding the shape of the fins, a convenient arrangement can be selected according to actual needs. Preferably, the fins are wavy or V-shaped. Between the cold-side heat exchange tube 3 and the second heat exchange tube 4, the fins can be a continuous structure, that is, the fins are arranged continuously to achieve a larger heat dissipation area; or they can be a discontinuous structure, that is, the fins are spaced a certain distance apart, and key areas can be selected for enhanced heat transfer, so as to save materials and simplify the manufacturing process while ensuring heat dissipation effect.
[0057] Example 2
[0058] Please refer to Figures 5-10 As shown, in Embodiment 2, the first heat exchange tube 3 can be configured in a double-row or multi-row configuration. Several rows of the first heat exchange tubes 3 are arranged side-by-side along a direction perpendicular to the alternating arrangement of the first and second heat exchange tubes 4, and the first medium between these rows is sequentially connected. Similarly, the second heat exchange tube 4 can also be configured in a double-row or multi-row configuration. Several rows of the second heat exchange tubes 4 are arranged side-by-side along a direction perpendicular to the alternating arrangement of the first and second heat exchange tubes 4, and the second medium between these rows is sequentially connected. The specific configuration is not limited in this embodiment; this embodiment only uses a double-row configuration of the first heat exchange tubes 3 as an example for illustration.
[0059] In this embodiment, it should be noted that the direction in which the first heat exchange tube 3 and the second heat exchange tube 4 are alternately arranged between the upper manifold 1 and the lower manifold 2 is defined as the X direction, the direction perpendicular to the X direction is defined as the Y direction, and the height direction of the first heat exchange tube 3 and the second heat exchange tube 4 is defined as the Z direction.
[0060] In some embodiments, the first heat exchange tubes 3 are arranged in two rows along a direction perpendicular to the alternating arrangement of the first heat exchange tubes 3 and the second heat exchange tubes 4, that is, along a Y direction perpendicular to the X direction, and the first medium between the two rows of first heat exchange tubes 3 is connected.
[0061] The second heat exchange tube 4 is configured as a wide flat tube, and the first heat exchange tube 3 is configured as a narrow flat tube. When a wide flat tube 4 is configured as the second heat exchange tube, two, three or more narrow flat tubes can be configured as the first heat exchange tube 3. Of course, in this embodiment, only the example of a first heat exchange tube 3 configured as two narrow flat tubes is used for illustration.
[0062] When the second heat exchange tube 4 is configured as a wide flat tube and the first heat exchange tube 3 is configured as a narrow flat tube, and taking the example of the upper end of the first heat exchange tube 3 being connected to the second liquid collection chamber 12 and the lower end being connected to the fourth liquid collection chamber 22, and the upper end of the second heat exchange tube 4 being connected to the first liquid collection chamber 11 and the lower end being connected to the third liquid collection chamber 21, an upper partition 19 is provided in the second liquid collection chamber 12. The upper partition 19 extends along the X direction and is located between two adjacent rows of first heat exchange tubes 3 to isolate the two rows of first heat exchange tubes 3. Of course, the ends of the first heat exchange tubes 3 in the same row located in the second liquid collection chamber 12 are interconnected. The upper partition 19 is provided with a flow hole 6 for the first medium to flow through. That is to say, the first heat exchange tubes 3 between rows are connected through the flow hole 6 opened on the upper partition 19. A lower partition 23 is provided in the fourth liquid collection chamber 22. The lower partition 23 extends along the X direction and is located between two adjacent rows of first heat exchange tubes 3 to isolate the two rows of first heat exchange tubes 3. The lower partition 23 divides the fourth liquid collection chamber 22 into a first liquid inlet chamber 14 and a first liquid outlet chamber 15. The first inlet pipe is located at one end of the lower collection pipe 2 and is connected to the first liquid inlet chamber 14. The first outlet pipe is located at one end of the lower collection pipe 2 and is connected to the first liquid outlet chamber 15. Thus, the first medium enters the first liquid inlet chamber 14 through the first inlet pipe. In the first liquid inlet chamber 14, the first medium is distributed along the X direction to several first heat exchange tubes 3 in the same row. The first medium flows from the lower end of the several first heat exchange tubes 3 upward, that is, along the Z direction, and then flows into the second liquid collection chamber 12. In the second liquid collection chamber 12, the first medium flows along the Y direction, and then flows through the flow hole 6 on the upper partition 19 to the next row of first heat exchange tubes 3. Then it flows from the upper end of the first heat exchange tubes 3 downward, that is, along the Z direction, and then flows into the first liquid outlet chamber 15. The first medium in the first liquid outlet chamber 15 flows out through the first outlet pipe along the X direction. In this method, the flow direction of the first medium in the second liquid collection chamber 12 is from the inside to the outside, that is, along the Y direction. The flow direction of the first medium is exactly opposite to the direction of air inlet, and they are in counter-current contact. Through counter-current contact, the cooling and heat exchange performance can be improved. At the same time, the first medium in each row of the first heat exchange tube 3 flows from the inside to the outside at the same time, which can ensure the uniformity of the air outlet at the front and back, and effectively improve the cooling and heat exchange performance.
[0063] In the above configuration, a first partition 13 is provided in the first liquid collection chamber 11, which divides the first liquid collection chamber 11 into a second liquid inlet chamber 17 and a second liquid outlet chamber 18. The second inlet pipe is located at one end of the upper manifold 1 and is connected to the second liquid inlet chamber 17. The second outlet pipe is located at the other end of the upper manifold 1 and is connected to the second liquid outlet chamber 18. The upper ends of all the second heat exchange tubes 4 in the second liquid inlet chamber 17 are connected. The upper ends of all the second heat exchange tubes 4 in the second liquid outlet chamber 18 are connected. The lower ends of all the second heat exchange tubes 4 in the third liquid collection chamber 21 are connected. Thus, the second medium enters the second liquid inlet chamber 17 through the second inlet pipe. In the second liquid inlet chamber 17, the second medium is distributed from left to right along the X direction to several second heat exchange tubes 4. The second medium flows from the upper end of several second heat exchange tubes 4 to the lower end, and then flows into the third liquid collection chamber 21. In the third liquid collection chamber 21, the second medium flows from left to right along the X direction. It flows from the lower end of the second heat exchange tubes 4 to the upper end, that is, along the Z direction, and then flows into the second liquid outlet chamber 18, and then flows out through the second outlet pipe.
[0064] In one example, an upper horizontal partition 7 is provided inside the upper manifold 1, dividing the interior of the upper manifold 1 into two layers, namely the first liquid collection chamber 11 and the second liquid collection chamber. An upper partition 19 is connected to the lower surface of the upper horizontal partition 7, with its bottom abutting against the bottom of the second liquid collection chamber 12. The top of the first partition 13 is connected to the top of the first liquid collection chamber 11, and its bottom abuts against the upper surface of the upper horizontal partition 7. This allows the upper partition 19 and the upper horizontal partition 7 to be integrated as a single unit, detachably connected within the upper manifold 1, thus facilitating assembly. Furthermore, the upper partition 19 is provided in multiple segments along its length, with the space between adjacent upper partitions 19 precisely accommodating the insertion of the second heat exchange tube 4.
[0065] The lower manifold 2 is provided with a lower horizontal partition 8, which divides the interior of the lower manifold 2 into two layers, namely the third liquid collection chamber 21 and the fourth liquid collection chamber 22. The lower horizontal partition 8 can also be assembled in the lower manifold 2 in a detachable manner.
[0066] Alternatively, the second heat exchange tube 4 can be configured as a narrow, flat tube arranged in two rows, while the first heat exchange tube 3 can be configured as a wide, flat tube. In this case, the upper baffle 19 is located within the first liquid collection chamber 11, and is positioned between two adjacent rows of the second heat exchange tubes 4. The lower baffle 23 is located within the third liquid collection chamber 21, dividing the third liquid collection chamber 21 into a second inlet chamber 17 and a second outlet chamber 18. The second inlet pipe is located at one end of the lower manifold 2 and is connected to the second inlet chamber 17. The second outlet pipe is located at one end of the lower manifold 2 and is connected to the second outlet chamber 18. With this configuration, the flow direction of the second medium is from the inside out, i.e., along the Y direction, which is exactly opposite to the direction of the air inlet. At this time, the second partition 16 is set in the second liquid collection chamber 12, and the second partition 16 divides the second liquid collection chamber 12 into the first liquid inlet chamber 14 and the first liquid outlet chamber 15; the first inlet pipe is set at one end of the upper collection pipe 1 and is connected to the first liquid inlet chamber 14, and the first outlet pipe is set at the other end of the upper collection pipe 1 and is connected to the first liquid outlet chamber 15.
[0067] For other situations, the underlying principles are the same as described above, and will not be elaborated upon in detail in this embodiment.
[0068] This embodiment also provides an automotive air conditioner, including the aforementioned automotive air conditioner dual-function (cooling and heating) integrated core.
[0069] This embodiment also provides a vehicle, including the aforementioned automotive air conditioner.
[0070] The implementation principle of this embodiment is as follows: In this embodiment, the heating core and the cooling core are made into an integrated core. This integrated core can save space in the air conditioning unit, is lighter, and reduces production costs and raw material input compared to the independent structure in the prior art. At the same time, it is more convenient and easier to install. In addition, the upper manifold 1 and the lower manifold 2 are both set in a double-layer form. The upper manifold 1 and the lower manifold 2 can be used as liquid collection pipes for the first heat exchange pipe 3 or the second heat exchange pipe 4.
