Consequently, the figures are substantially schematic, and their shapes are not intended to show the actual shape of the device and are not intended to limit the scope of this application.
[0048] Referring to Figures 1 and 2, an exemplary description of a heat exchanger according to a first embodiment of this application will be provided.
[0049] The heat exchanger includes a first heat exchange component 100 and a second heat exchange component 200 connected in series. The first heat exchange component 100 has a first heat exchange medium flow path, and the second heat exchange component 200 has a second heat exchange medium flow path. The flow rates or velocities of the heat exchange medium in the first heat exchange medium flow path and the second heat exchange medium flow path are different.
[0050] The first heat exchange component 100 and the second heat exchange component 200 can be used to exchange heat with air or other media. Thus, the first heat exchange component 100 and the second heat exchange component 200 can achieve different degrees of heat exchange. That is, the air or other media in the corresponding areas of the first heat exchange component 100 and the second heat exchange component 200 can be heated to different temperatures. As a result, the heat exchanger can achieve multi-temperature zone function, making the heat exchanger more functional and its application scenarios more extensive.
[0051] In this embodiment, the first heat exchange component 100 includes a first manifold 110, a second manifold 120, and a first heat exchange tube group 130. The first manifold 110 and the second manifold 120 are located at the two ends of the first heat exchange tube group 130, and the first manifold 110, the second manifold 120, and the first heat exchange tube group 130 together form a first heat exchange medium flow path.
[0052] The second heat exchange assembly 200 includes a first manifold 110, a third manifold 220, and a second heat exchange tube group 230. That is, the first heat exchange assembly 100 and the second heat exchange assembly 200 share the first manifold 110. The first manifold 110 and the third manifold 220 are located at opposite ends of the second heat exchange tube group 230, and the first manifold 110, the third manifold 220, and the second heat exchange tube group 230 together form the second heat exchange medium flow path.
[0053] The second manifold 120 and the third manifold 220 are not connected to each other (here, "not connected to each other" means that the manifolds themselves are not directly connected). The second manifold 120 is provided with a first heat exchange medium inlet 111, and the third manifold 220 is provided with a second heat exchange medium inlet 221. The first heat exchange medium flow path and the second heat exchange medium flow path share a first heat exchange medium outlet 111, which is located in the first manifold 110.
[0054] The heat exchange medium entering the first heat exchange medium flow path from the first heat exchange medium inlet 111 flows sequentially through the second manifold 120, the first heat exchange tube group 130 and the first manifold 110, and finally exits from the first heat exchange medium outlet 111; the heat exchange medium entering the second heat exchange medium flow path from the second heat exchange medium inlet 221 flows sequentially through the third manifold 220, the second heat exchange tube group 230 and the first manifold 110, and finally exits from the first heat exchange medium outlet 111.
[0055] The same heat exchange medium can pass through the first heat exchange medium flow path and the second heat exchange medium flow path, but the flow rate or velocity of the heat exchange medium is different. Therefore, when the heat exchange medium with different flow rates or velocities passes through the first heat exchange tube group 130 and the second heat exchange tube group 230, it can exchange heat to different temperatures for the air or other gas medium flowing outside the first heat exchange tube group 130 and the second heat exchange tube group 230, so as to achieve zoned heat exchange with two temperature zones.
[0056] In this embodiment, the first heat exchange tube group 130 and the second heat exchange tube group 230 are arranged side by side on the same plane. The second manifold 120 and the third manifold 220 are connected in sequence. Exemplarily, the second manifold 120 and the third manifold 220 may share a portion of the tube wall. For example, the tube wall of the second manifold 120 away from the first heat exchange medium inlet 111 and the tube wall of the third manifold 220 away from the second heat exchange medium inlet 221 may share a single tube wall to save material. In some embodiments, the second manifold 120 and the third manifold 220 may be two independent manifolds (not sharing a common wall) connected together only by connection methods commonly used in the art, such as welding.
[0057] In this embodiment, both the first heat exchange tube group 130 and the second heat exchange tube group 230 include multiple flat tubes arranged in parallel at intervals. The multiple flat tubes in the first heat exchange tube group 130 and the multiple flat tubes in the second heat exchange tube group 230 are located on the same plane. Exemplarily, the flat tubes in the first heat exchange tube group 130 and the second heat exchange tube group 230 can be porous flat tubes, internally finned flat tubes, or corrugated flat tubes.
[0058] In some other embodiments, the first heat exchanger tube group 130 and the second heat exchanger tube group 230 may also include multiple parallel and spaced round tubes, square tubes or other shaped heat exchanger tubes, with the multiple heat exchanger tubes in the first heat exchanger tube group 130 located on the same plane, and the multiple heat exchanger tubes in the second heat exchanger tube group 230 located on the same plane.
[0059] In some other embodiments, the first heat exchange tube group 130 and the second heat exchange tube group 230 may not be arranged side by side on the same plane. The plane in which multiple heat exchange tubes in the first heat exchange tube group 130 are located may be parallel to or at a certain angle to the plane in which multiple heat exchange tubes in the second heat exchange tube group 230 are located. Those skilled in the art can configure it according to the actual application scenario of the heat exchanger.
[0060] In this embodiment, the heat exchanger also includes fins 500, which are connected to the first heat exchange tube group 130 and the second heat exchange tube group 230 to further increase the heat exchange area and enhance the heat exchange effect between the first heat exchange tube group 130, the second heat exchange tube group 230 and the incoming air.
[0061] For example, there are multiple fins 500, and multiple fins 500 are connected to the first heat exchange tube group 130 and the second heat exchange tube group 230. The fins 500 can be connected between two adjacent heat exchange tubes in the heat exchange tube group. For example, the fins 500 can be straight fins, louvered fins, serrated fins, porous fins or corrugated fins.
[0062] According to the heat exchanger of this embodiment, when the heat exchanger needs to achieve the heating function, high-temperature refrigerants with different flow rates or velocities can be introduced into the first heat exchange medium flow path and the second heat exchange medium flow path, respectively. Thus, the first heat exchange tube group 130 and the second heat exchange tube group 230 can respectively raise the temperature of the incoming air passing through them to different temperatures, achieving the function of two temperature zones. The temperatures of the two temperature zones can be adjusted independently. Specifically, this can be achieved by adjusting the flow rate or velocity of the high-temperature refrigerant entering the first heat exchange medium flow path and the second heat exchange medium flow path. It should be noted that the incoming air through the first heat exchange tube group 130 and the second heat exchange tube group 230 refers to air or other gaseous media flowing from outside the heat exchange tubes in the first heat exchange tube group 130 and the second heat exchange tube group 230.
[0063] According to the heat exchanger of this embodiment, when the heat exchanger needs to realize the cooling function, low-temperature refrigerant with different flow rates or flow velocities can be introduced into the first heat exchange medium flow path and the second heat exchange medium flow path respectively. As a result, the first heat exchange tube group 130 and the second heat exchange tube group 230 can cool the incoming air passing through them to different temperatures respectively, realizing the function of two temperature zones. The temperature of the two temperature zones can be adjusted independently. Specifically, this can be achieved by adjusting the flow rate or flow velocity of the low-temperature refrigerant entering the first heat exchange medium flow path and the second heat exchange medium flow path.
[0064] Referring to Figures 3 and 4, a heat exchanger according to a second embodiment of this application will be described exemplarily. The heat exchanger includes a first heat exchange component 100, a second heat exchange component 200, and a third heat exchange component 300 that are connected in series. The first heat exchange component 100 has a first heat exchange medium flow path, the second heat exchange component 200 has a second heat exchange medium flow path, and the third heat exchange component 300 has a third heat exchange medium flow path. The flow rates or velocities of the heat exchange medium in the first, second, and third heat exchange medium flow paths are different. The first heat exchange component 100, the second heat exchange component 200, and the third heat exchange component 300 can be used to exchange heat with air or other media. Thus, the first heat exchange component 100, the second heat exchange component 200, and the third heat exchange component 300 can achieve different degrees of heat exchange. That is, the air or other media in the corresponding areas of the first heat exchange component 100, the second heat exchange component 200, and the third heat exchange component 300 can be heated to different temperatures. As a result, the heat exchanger can achieve multi-temperature zone function, making the heat exchanger more functional and its application scenarios more extensive.
[0065] In this embodiment, the first heat exchange component 100 includes a first manifold 110, a second manifold 120, and a first heat exchange tube group 130. The first manifold 110 and the second manifold 120 are located at the two ends of the first heat exchange tube group 130, and the first manifold 110, the second manifold 120, and the first heat exchange tube group 130 together form a first heat exchange medium flow path.
[0066] The second heat exchange assembly 200 includes a first manifold 110, a third manifold 220, and a second heat exchange tube group 230. That is, the first heat exchange assembly 100 and the second heat exchange assembly 200 share the first manifold 110. The first manifold 110 and the third manifold 220 are located at opposite ends of the second heat exchange tube group 230, and the first manifold 110, the third manifold 220, and the second heat exchange tube group 230 together form the second heat exchange medium flow path.
[0067] The third heat exchange assembly 300 includes a first manifold 110, a manifold 320, and a heat exchange tube group 330. That is, the first heat exchange assembly 100, the second heat exchange assembly 200, and the third heat exchange assembly 300 share the first manifold 110. The first manifold 110 and the manifold 320 are located at opposite ends of the heat exchange tube group 330, and the first manifold 110, the manifold 320, and the heat exchange tube group 330 together form the third heat exchange medium flow path.
[0068] The second manifold 120, the third manifold 220, and the manifold 320 are not interconnected (meaning they are not directly connected). The second manifold 120 is provided with a first heat exchange medium inlet 111, the third manifold 220 is provided with a second heat exchange medium inlet 221, and the manifold 320 is provided with a heat exchange medium inlet 321. The first heat exchange medium flow path, the second heat exchange medium flow path, and the third heat exchange medium flow path share a first heat exchange medium outlet 111, which is located in the first manifold 110.
[0069] The heat exchange medium entering the first heat exchange medium flow path from the first heat exchange medium inlet 111 flows sequentially through the second manifold 120, the first heat exchange tube group 130, and the first manifold 110, and finally exits from the first heat exchange medium outlet 111; the heat exchange medium entering the second heat exchange medium flow path from the second heat exchange medium inlet 221 flows sequentially through the third manifold 220, the second heat exchange tube group 230, and the first manifold 110, and finally exits from the first heat exchange medium outlet 111; the heat exchange medium entering the third heat exchange medium flow path from the heat exchange medium inlet 321 flows sequentially through the manifold 320, the heat exchange tube group 330, and the first manifold 110, and finally exits from the first heat exchange medium outlet 111.
[0070] The first, second, and third heat exchange medium flow paths can all use the same heat exchange medium, but the flow rates or velocities of the heat exchange mediums are different. Thus, when the heat exchange mediums with different flow rates or velocities pass through the first heat exchange tube group 130, the second heat exchange tube group 230, and the heat exchange tube group 330, they can exchange heat to different temperatures on the air or other gaseous media flowing outside the first heat exchange tube group 130, the second heat exchange tube group 230, and the heat exchange tube group 330, achieving zoned heat exchange with three temperature zones.
[0071] In this embodiment, the first heat exchange tube group 130, the second heat exchange tube group 230, and the heat exchange tube group 330 are arranged side by side on the same plane. The second manifold 120, the third manifold 220, and the manifold 320 are connected sequentially. Exemplarily, the second manifold 120, the third manifold 220, and the manifold 320 may share a portion of the tube wall. In some embodiments, the second manifold 120, the third manifold 220, and the manifold 320 may be three independent manifolds (not sharing walls), connected together only by connection methods commonly used in the art, such as welding.
[0072] In this embodiment, the first heat exchanger tube group 130, the second heat exchanger tube group 230, and the heat exchanger tube group 330 all include multiple flat tubes arranged in parallel and spaced apart. The multiple flat tubes in the first heat exchanger tube group 130, the second heat exchanger tube group 230, and the heat exchanger tube group 330 are all located on the same plane. Exemplarily, the flat tubes in the first heat exchanger tube group 130, the second heat exchanger tube group 230, and the heat exchanger tube group 330 can be porous flat tubes, internally finned flat tubes, or corrugated flat tubes. In other embodiments, the first heat exchanger tube group 130, the second heat exchanger tube group 230, and the heat exchanger tube group 330 may also include multiple parallel and spaced-apart round tubes, square tubes, or other shaped heat exchanger tubes, with the multiple heat exchanger tubes in the first heat exchanger tube group 130, the second heat exchanger tube group 230, and the heat exchanger tube group 330 all located on the same plane. In some other embodiments, the first heat exchanger tube group 130, the second heat exchanger tube group 230 and the heat exchanger tube group 330 may not be arranged side by side on the same plane. The plane in which multiple heat exchanger tubes in the first heat exchanger tube group 130 are located, the plane in which multiple heat exchanger tubes in the second heat exchanger tube group 230 are located and the plane in which multiple heat exchanger tubes in the heat exchanger tube group 330 are located may be parallel or at a certain angle. Those skilled in the art can configure them according to the actual application scenario of the heat exchanger.
[0073] In this embodiment, the heat exchanger further includes fins 500, which are connected to the first heat exchange tube group 130, the second heat exchange tube group 230, and the heat exchange tube group 330 to further increase the heat exchange area and enhance the heat exchange effect between the first heat exchange tube group 130, the second heat exchange tube group 230, and the incoming air. Exemplarily, there are multiple fins 500, with multiple fins 500 connected to the first heat exchange tube group 130, the second heat exchange tube group 230, and the heat exchange tube group 330. Fins 500 can be connected between two adjacent heat exchange tubes in a heat exchange tube group. Exemplarily, the fins 500 can be straight fins, louvered fins, serrated fins, porous fins, or corrugated fins.
[0074] Referring to Figures 5 to 9, a heat exchanger according to a third embodiment of this application will be described exemplarily. The heat exchanger includes a first heat exchange component 100 and a second heat exchange component 200 connected in communication. The specific structure and connection method of the first heat exchange component 100 and the second heat exchange component 200 are the same as those of the first heat exchange component and the second heat exchange component 200 in the first embodiment, and will not be repeated here.
[0075] In this embodiment, the heat exchanger further includes a fourth manifold 410, a fifth manifold 420, and a third heat exchange tube group 430. The fourth manifold 410 and the fifth manifold 420 are located at both ends of the third heat exchange tube group 430. The fourth manifold 410 and the fifth manifold 420 are respectively provided with a second heat exchange medium outlet 411 and a third heat exchange medium inlet 421. The fourth manifold 410, the fifth manifold 420, and the third heat exchange tube group 430 together form the third heat exchange medium flow path.
[0076] In this embodiment, the third heat exchange tube group 430 is arranged parallel to both the first heat exchange tube group 130 and the second heat exchange tube group 230. The third heat exchange tube group 430 includes multiple flat tubes arranged in parallel and spaced apart. The multiple flat tubes in the first heat exchange tube group 130, the multiple flat tubes in the second heat exchange tube group 230, and the multiple flat tubes in the third heat exchange tube group 430 are all located on the same plane. Exemplarily, the flat tubes in the third heat exchange tube group 430 can be porous flat tubes, internally finned flat tubes, or corrugated flat tubes. In some other embodiments, the third heat exchange tube group 430 may also include multiple parallel and spaced-apart round tubes, square tubes, or other shaped heat exchange tubes, with the multiple heat exchange tubes in the third heat exchange tube group 430 located on the same plane.
[0077] In this embodiment, the third heat exchanger tube group 430, the first heat exchanger tube group 130, and the second heat exchanger tube group 230 can exchange heat with the incoming air passing through the heat exchanger sequentially. That is, the incoming air can first flow through the third heat exchanger tube group 430 to exchange heat with it, and then flow through the first heat exchanger tube group 130 and the second heat exchanger tube group 230 respectively, exchanging heat with them respectively. The third heat exchanger tube group 430 can be used to heat or cool the incoming air, and the first heat exchanger tube group 130 and the second heat exchanger tube group 230 can be used for zoned temperature regulation.
[0078] When the heat exchange medium through the third heat exchange medium flow path is a high-temperature refrigerant (or coolant), the heat exchange medium through the first heat exchange medium flow path and the second heat exchange medium flow path can be low-temperature refrigerants (or coolants) with different flow rates or velocities. Thus, the first heat exchange tube group 130 can raise the temperature of the incoming air passing through it to a suitable temperature, and the first heat exchange tube group 130 and the second heat exchange tube group 230 can cool the incoming air passing through them to different temperatures, thereby realizing zoned temperature control and regulation, and achieving multi-temperature zone function. Correspondingly, when the heat exchange medium through the third heat exchange medium flow path is a low-temperature refrigerant (or coolant), the heat exchange medium through the first heat exchange medium flow path and the second heat exchange medium flow path can be high-temperature refrigerants (or coolants) with different flow rates or velocities. Thus, the first heat exchange tube group 130 can cool the incoming air passing through it to a suitable temperature, and the first heat exchange tube group 130 and the second heat exchange tube group 230 can respectively heat the incoming air passing through them to different temperatures, thereby realizing zoned temperature control and regulation.
[0079] In this embodiment, the first manifold 110 and the fourth manifold 410 are arranged in parallel, and the fifth manifold 420 is also arranged in parallel with the second manifold 120 and the third manifold 220. The first manifold 110 and the fourth manifold 410 are located at the upper and lower ends of the heat exchanger in Figure 6, respectively, and the fifth manifold 420 and the second manifold 120 and the third manifold 220 can also be located at the upper and lower ends of the heat exchanger in Figure 6, respectively. This arrangement makes the overall structure of the heat exchanger more compact and reduces space occupation. Correspondingly, in this embodiment, the flat tubes in the first heat exchange tube group 130, the second heat exchange tube group 230, and the third heat exchange tube group 430 are all parallel to each other.
[0080] In some other embodiments, the first manifold 110 and the fourth manifold 410 may be perpendicular to each other, and the fifth manifold 420 may be perpendicular to both the second manifold 120 and the third manifold 220. For example, the first manifold 110 and the fourth manifold 410 are located at the upper and lower ends of the heat exchanger in Figure 6, respectively, and the fifth manifold 420 is located at the left and right ends of the heat exchanger in Figure 6, respectively, along with the second manifold 120 and the third manifold 220. Correspondingly, the flat tubes in the third heat exchanger tube group 430 are perpendicular to the flat tubes in the first heat exchanger tube group 130 and the second heat exchanger tube group 230.
[0081] In this embodiment, a first gap exists between the first manifold 110 and the fourth manifold 410, and a second gap exists between the fifth manifold 420 and both the second manifold 120 and the third manifold 220. That is, a certain distance exists between the first manifold 110 and the fourth manifold 410, and a certain distance exists between the fifth manifold 420 and both the second and third manifolds 220. This effectively prevents direct heat exchange between the first manifold 110 and the fourth manifold 410, and also prevents direct heat exchange between the fifth manifold 420 and both the second and third manifolds 220, thereby effectively reducing heat loss. Referring to Figure 9, in this embodiment, the heat exchanger also includes an end cover 600, which includes a first cover plate 610 and a second cover plate 620, with the second cover plate 620 vertically disposed in the middle of the first cover plate 610. The second cover plate 620 is inserted between the first manifold 110 and the fourth manifold 410, forming a gap between the first manifold 110 and the fourth manifold 410. The ends of the first cover plate 610 and the first manifold 110 and the fourth manifold 410 are fitted together. The end cap 600 can be connected to the first manifold 110 and the fourth manifold 410 by welding.
[0082] In this embodiment, a first heat insulation element is provided in the first interval, and a second heat insulation element is provided in the second interval. The first and second heat insulation elements can be heat insulation elements known to those skilled in the art, such as aerogel and composite foam. By providing the first and second heat insulation elements, heat exchange between the first manifold 110 and the fourth manifold 410 can be more effectively limited, as can heat exchange between the fifth manifold 420 and the second manifold 120 and the third manifold 220, thereby more effectively reducing heat loss.
[0083] In this embodiment, the heat exchanger further includes fins 500. The first heat exchange tube group 130 and the third heat exchange tube group 430 are connected by fins 500, and the second heat exchange tube group 230 and the third heat exchange tube group 430 are also connected by fins 500. That is, the outer wall of the heat exchange tubes in the first heat exchange tube group 130 is connected to the outer wall of a portion of the heat exchange tubes in the third heat exchange tube group 430 by multiple fins 500, and the outer wall of the heat exchange tubes in the second heat exchange tube group 230 is connected to the outer wall of another portion of the heat exchange tubes in the third heat exchange tube group 430 by multiple fins 500. It should be noted that "connected by fins 500" here means simultaneously connected to the fins 500. The arrangement of fins 500 can further increase the heat exchange area and enhance the heat exchange effect between the first heat exchange tube group 130, the second heat exchange tube group 230, and the third heat exchange tube group 430 and the incoming air. In some embodiments, the fin 500 can be a straight fin, a louvered fin, a serrated fin, a porous fin, or a corrugated fin.
[0084] Referring to Figure 8, in this embodiment, the fin 500 includes a plurality of parallel and spaced heat exchange plates 510 and a plurality of connecting plates 520. Adjacent heat exchange plates 510 are connected by connecting plates 520, thereby the plurality of heat exchange plates 510 and the plurality of connecting plates 520 can form a whole, achieving integral installation and simplifying the installation process. In this embodiment, the plurality of heat exchange plates 510 and the plurality of connecting plates 520 are corrugated in shape, and the plurality of heat exchange plates 510 and the plurality of connecting plates 520 can be integrally formed, that is, they can be formed from a single plate by bending.
[0085] The first part 510A of the heat exchange plate 510 has a plurality of parallel and spaced first fins 511. The first part 510A of the heat exchange plate 510 is located between two adjacent heat exchange tubes in the first heat exchange tube group 130 or between two adjacent heat exchange tubes in the second heat exchange tube group 230. That is, the plurality of first fins 511 are located between two adjacent heat exchange tubes in the first heat exchange tube group 130 or between two adjacent heat exchange tubes in the second heat exchange tube group 230, so as to increase the heat exchange area. The second part 510B of the heat exchange plate 510 has a plurality of parallel and spaced second fins 512. The second part 510B of the heat exchange plate 510 is located between two adjacent heat exchange tubes in the third heat exchange tube group 430. That is, the plurality of second fins 512 are located between two adjacent heat exchange tubes in the third heat exchange tube group 430, so as to increase the heat exchange area. When the fins 500 are simultaneously connected to the first heat exchanger tube group 130 and the third heat exchanger tube group 430, the first part 510A of the heat exchanger plate 510 is located between two adjacent heat exchanger tubes in the first heat exchanger tube group 130, and the second part 510B of the heat exchanger plate 510 is located between two adjacent heat exchanger tubes in the third heat exchanger tube group 430; when the fins 500 are simultaneously connected to the second heat exchanger tube group 230 and the third heat exchanger tube group 430, the first part 510A of the heat exchanger plate 510 is located between two adjacent heat exchanger tubes in the second heat exchanger tube group 230, and the second part 510B of the heat exchanger plate 510 is located between two adjacent heat exchanger tubes in the third heat exchanger tube group 430.
[0086] The heat exchange plate 510 also has at least one perforated portion 513, which is located between the first portion 510A and the second portion 510B of the heat exchange plate 510. The perforated portion can effectively reduce the area of the connection between the first portion 510A and the second portion 510B of the heat exchange plate 510, thereby reducing direct heat transfer between them and effectively reducing unnecessary heat loss.
