Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a heat exchanger and heat pump system. Background Technology

[0002] Heat exchangers are crucial components in heat pump systems, absorbing heat from the environment and transferring it to the refrigerant. A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play a vital role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers. In double-layer heat exchangers, the manifolds typically use circular tubes for liquid flow. The contact between the upper and lower circular tubes is relatively small, usually requiring manual alignment before welding or other connection methods are used to connect the two tubes.

[0003] In the process of realizing this application, the inventors discovered that manually aligning the upper and lower manifolds is inefficient. Utility Model Content

[0006] In an alternative embodiment, the heat exchanger further includes two second manifolds, which are spaced apart and are in communication with the first manifold.

[0007] In one alternative embodiment, the heat exchanger further includes a second positioning element disposed between the two second manifolds. One side of the second positioning element is connected to one of the second manifolds, and the other side of the second positioning element is connected to the other second manifold.

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see Figure 1 and Figure 2 The heat exchanger 1000 includes a first manifold 10 and a first positioning member 20. Two first manifolds 10 are spaced apart, and the first positioning member 20 is disposed between the two first manifolds 10. One side of the first positioning member 20 is connected to one first manifold 10, and the other side of the first positioning member 20 is connected to the other first manifold 10. The first positioning member 20 is used to position the two first manifolds 10.

[0029] The heat exchanger 1000 also includes a second manifold 30, a second positioning element 40, and a flat tube 50. Two second manifolds 30 are spaced apart and are interconnected with the first manifold 10 via the flat tube 50. The second positioning element 40 is positioned between the two second manifolds 30, with one side connected to one second manifold 30 and the other side connected to the other second manifold 30. The second positioning element 40 is used to position the two second manifolds 30. The first manifold 10, the first positioning element 20, the second manifold 30, the second positioning element 40, and the flat tube 50 are described in detail below.

[0030] Regarding the aforementioned first manifold 10 and first positioning element 20, as Figure 2 and Figure 3As shown, two first manifolds 10 are spaced apart, and a first positioning member 20 is disposed between the two first manifolds 10. One side of the first positioning member 20 is connected to one first manifold 10, and the other side is connected to the other first manifold 10. The first positioning member 20 can position the two first manifolds 10. Compared with the related technology, which uses manual alignment, the traditional manual alignment method requires multiple adjustments and calibrations, which is complex and time-consuming. In this application, the first positioning member 20 is used to position the two first manifolds 10, which can simplify the installation steps and improve assembly efficiency. The first positioning member 20 can provide stable support and fixation for the two first manifolds 10, ensuring that the relative positions of the first manifolds 10 remain unchanged during operation, thereby enhancing the overall structural stability of the heat exchanger. It is understood that the connection method between the first positioning member 20 and the first manifold 10 includes, but is not limited to, snap-fit, welding, screw connection, etc.

[0031] In some embodiments, the two first manifolds 10 are not interconnected, and the first positioning member 20 and the first manifold 10 are not internally interconnected. The fact that the two first manifolds 10 are not interconnected means that they can each carry different fluids or fluids in different states (such as different phases of refrigerant), thereby achieving more flexible fluid distribution and control. At the same time, the fact that the first positioning member 20 and the first manifold 10 are not internally interconnected ensures the independence of the fluid within the first manifold 10, avoiding the mixing of fluids between the first positioning member 20 and the first manifold 10. The independent fluid channels and the non-interconnected design reduce the risk of fluid leakage.

[0032] In some embodiments, the two first manifolds 10 are interconnected, and the first positioning member 20 is internally interconnected with the first manifold 10. Through the internal connectivity between the first positioning member 20 and the first manifold 10, the fluid can flow more smoothly between the heat exchanger components, reducing flow resistance and thus improving heat exchange efficiency. The connectivity between the first positioning member 20 and the first manifold 10 not only helps with fluid distribution but also enhances the structural stability of the heat exchanger. This arrangement can reduce structural deformation caused by uneven fluid pressure.

[0033] In some embodiments, the first positioning member 20 includes a plurality of adjacently arranged first arc-shaped portions 201 and second arc-shaped portions 202. The plurality of first arc-shaped portions 201 are arranged parallel and spaced apart, and the plurality of second arc-shaped portions 202 are arranged parallel and spaced apart. The first arc-shaped portions 201 are provided with a first arc-shaped groove 201a, and the second arc-shaped portions 202 are provided with a second arc-shaped groove 202a. The lower surface of one first manifold 10 at least partially abuts against the bottom of the first arc-shaped groove 201a, and the upper surface of the other first manifold 10 at least partially abuts against the bottom of the second arc-shaped groove 202a. The first arc-shaped groove 201a and the second arc-shaped groove 202a can accurately support the upper and lower surfaces of the two first manifolds 10 respectively, ensuring that the two first manifolds 10 maintain a stable positional relationship during assembly. Through the tight fit between the arc-shaped grooves and the first manifolds 10, the vibration and displacement of the first manifolds 10 during operation can be effectively reduced, thereby enhancing the overall structural stability of the heat exchanger.

[0034] In some embodiments, a plurality of first arc-shaped grooves 201a are combined to form a first positioning groove (not shown), which is used to position one of the first manifolds 10, and a plurality of second arc-shaped grooves 202a are combined to form a second positioning groove (not shown), which is used to position another of the first manifolds 10.

[0035] In some embodiments, the opening of the first arc-shaped groove 201a faces upward, the opening of the second arc-shaped groove 202a faces downward, and the first arc-shaped portion 201 and the second arc-shaped portion 202 are curved in opposite directions.

[0036] In some embodiments, please refer to the following: Figure 4 The first manifold 10 is also provided with a liquid inlet 101 on its side wall. The liquid inlet 101 is connected to the inside of the first manifold 10 and is used to allow external fluid to enter the first manifold 10.

[0037] In some embodiments, a first mounting hole 102 is provided on the sidewall of the first manifold 10 opposite to the second manifold 30. The first mounting hole 102 is used to install one end of the flat tube 50, and the first mounting hole 102 communicates with the interior of the flat tube 50.

[0038] For the aforementioned second manifold 30, second positioning element 40, and flat tube 50, such as Figure 2As shown, two second manifolds 30 are spaced apart and are interconnected with the first manifold 10. One end of a flat tube 50 is connected to the first manifold 10, and the other end is connected to the second manifold 30. The flat tube 50 connects the first manifold 10 and the second manifold 30. A second positioning element 40 is disposed between the two second manifolds 30. One side of the second positioning element 40 is connected to one second manifold 30, and the other side is connected to the other second manifold 30. The second positioning element 40 can position the two second manifolds 30. Compared with the related technologies that use manual alignment, the traditional manual alignment method requires multiple adjustments and calibrations, which is complex and time-consuming. In this application, the second positioning element 40 is used to position the two second manifolds 30, which simplifies the installation steps and improves assembly efficiency. The second positioning element 40 can provide stable support and fixation for the two second manifolds 30, ensuring that the relative positions of the second manifolds 30 remain unchanged during operation, thereby enhancing the overall structural stability of the heat exchanger. It is understandable that the connection methods between the second positioning component 40 and the second manifold 30 include, but are not limited to, snap-fit, welding, screw-fit, etc.

[0039] In some embodiments, the two second manifolds 30 are not interconnected, and the second positioning member 40 and the second manifold 30 are not internally interconnected. The fact that the two second manifolds 30 are not interconnected means that they can each carry different fluids or fluids in different states, thereby achieving more flexible fluid distribution. At the same time, the fact that the second positioning member 40 and the second manifold 30 are not internally interconnected ensures the independence of the fluid within the second manifold 30, avoiding the mixing of fluids between the second positioning member 40 and the second manifold 30. The independent fluid channels and the non-interconnected design reduce the risk of fluid leakage.

[0040] In some embodiments, please refer to the following: Figure 5 and Figure 6 The two second manifolds 30 are interconnected, and the second positioning element 40 is internally interconnected with the second manifold 30. Through the interconnection design between the two second manifolds 30, the fluid can be distributed between the two second manifolds 30, avoiding local flow unevenness, thereby improving heat exchange efficiency. The connectivity between the second positioning element 40 and the second manifold 30 not only helps with fluid distribution, but also enhances the structural stability of the heat exchanger. This setting can reduce structural deformation caused by uneven fluid pressure.

[0041] In some embodiments, the second positioning member 40 includes a plurality of adjacently arranged third arc-shaped portions 401 and fourth arc-shaped portions 402. The plurality of third arc-shaped portions 401 are arranged parallel and spaced apart, and the plurality of fourth arc-shaped portions 402 are arranged parallel and spaced apart. The third arc-shaped portions 401 are provided with third arc-shaped grooves 401a, and the fourth arc-shaped portions 402 are provided with fourth arc-shaped grooves 402a. The lower surface of one second manifold 30 at least partially abuts against the bottom of the third arc-shaped groove 401a, and the upper surface of the other second manifold 30 at least partially abuts against the bottom of the fourth arc-shaped groove 402a. The third arc-shaped grooves 401a and fourth arc-shaped grooves 402a can accurately support the upper and lower surfaces of the two second manifolds 30 respectively, ensuring that the two second manifolds 30 maintain a stable positional relationship during assembly. Through the tight fit between the arc-shaped grooves and the second manifolds 30, the vibration and displacement of the second manifolds 30 during operation can be effectively reduced, thereby enhancing the overall structural stability of the heat exchanger.

[0042] In some embodiments, a plurality of third arc-shaped grooves 401a are combined to form a third positioning groove (not shown), which is used to position one of the second manifolds 30, and a plurality of fourth arc-shaped grooves 402a are combined to form a fourth positioning groove (not shown), which is used to position another of the second manifolds 30.

[0043] In some embodiments, the opening of the third arcuate groove 401a faces upward, the opening of the fourth arcuate groove 402a faces downward, and the third arcuate portion 401 and the fourth arcuate portion 402 are curved in opposite directions.

[0044] In some embodiments, a first liquid flow hole 301 is provided on one second manifold 30, and a second liquid flow hole 302 is provided on another second manifold 30. The second liquid flow hole 302 is connected to a third arc-shaped groove 401a. A connecting post 4011 extends from the third arc-shaped portion 401 toward one of the second manifolds 30. A connecting through hole 4011a is provided on the connecting post 4011, penetrating the third arc-shaped portion 401. The connecting through hole 4011a is connected to the third arc-shaped groove 401a. The connecting post 4011 is inserted into the first liquid flow hole 301. The first liquid flow hole 301, the connecting through hole 4011a, and the second liquid flow hole 302 are interconnected. Through the connection of the first liquid flow hole 301, the connecting through hole 4011a, and the second liquid flow hole 302, fluid can be distributed and flow between the two second manifolds 30. The design of the connecting column 4011 not only enables the fluid to be connected between the two second manifolds 30, but also enhances the structural stability of the heat exchanger. This design can reduce vibration and deformation caused by uneven fluid pressure, while making the overall design more compact.

[0045] It should be noted that: in order to achieve mutual connection between the two first manifolds 10, the connection method between the two first manifolds 10 can refer to the connection method between the two second manifolds 30 mentioned above, and will not be repeated here.

[0046] In some embodiments, a second mounting hole 303 is provided on the side wall of the second manifold 30 opposite to the first manifold 10. The second mounting hole 303 is used to install the other end of the flat tube 50. The second mounting hole 303 is disposed opposite to the first mounting hole 102 and communicates with the interior of the flat tube 50. It can be understood that the fluid can flow from the first mounting hole 102 through the flat tube 50 toward the second mounting hole 303, or the fluid can flow from the second mounting hole 303 through the flat tube 50 toward the first mounting hole 102. The user can set it according to actual needs, and no specific limitation is made in this application.

[0047] In this embodiment, two first manifolds 10 and a first positioning element 20 are provided. The two first manifolds 10 are spaced apart, and the first positioning element 20 is positioned between them. One side of the first positioning element 20 is connected to one first manifold 10, and the other side is connected to the other first manifold 10. The first positioning element 20 can position the two first manifolds 10. Compared to related technologies that use manual alignment, which requires multiple adjustments and calibrations and is complex and time-consuming, this application uses the first positioning element 20 to position the two first manifolds 10, simplifying the installation process and improving assembly efficiency. The first positioning element 20 provides stable support and fixation for the two first manifolds 10, ensuring that their relative positions remain unchanged during operation, thereby enhancing the overall structural stability of the heat exchanger.

[0048] This application also provides an embodiment of a heat pump system, which includes the heat exchanger 1000 as described above. The function and structure of the heat exchanger 1000 can be found in the above embodiments, and will not be repeated here.
