Technical Field

[0001] This application relates to the field of power electronics technology, specifically to a heat exchanger and electrical equipment. Background Technology

[0002] Typically, electrical equipment includes an internal air duct chamber and an external air duct chamber. A heat exchanger is installed at the connection between the internal and external air duct chambers, allowing for heat exchange between the hot airflow in the internal air duct chamber and the cooling airflow in the external air duct chamber, thus achieving effective heat dissipation for the electronic components inside the electrical equipment. However, the heat exchangers in related technologies suffer from inconvenience in disassembly and assembly, severely impacting the efficiency of electrical equipment assembly and maintenance.

[0004] In a first aspect, this application provides a heat exchanger, including an exchanger body, a first connecting end, and a second connecting end.

The main body is located on one side of the heat exchanger body along the third direction, and the flanged portion is located on one side of the heat exchanger body along the second direction. The heat exchanger is supported and assembled via the flanged portion. A portion of the flanged portion protrudes from the second connection end along the second direction in a direction away from the heat exchanger body.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the description of the embodiments of this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0021] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0022] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0023] Please refer to Figure 1 and Figure 2 , Figure 1This is a connection structure diagram of the housing, first partition, and second partition of an electrical device provided in an embodiment of this application; Figure 2 This is an internal structural diagram of an electrical device provided in an embodiment of this application.

[0024] like Figure 1 and Figure 2 As shown, this application embodiment provides an electrical device 1000, which may be, for example, a power converter in the form of an inverter, a power conversion system (PCS), etc. The electrical device 1000 includes a housing 1100 and a heat exchanger 1200.

[0025] The housing 1100 is the external structure of the electrical device 1000. In the electrical device 1000, such as the aforementioned heat exchanger 1200, it can be directly or indirectly mounted on the housing 1100 for integrated assembly. Simultaneously, the housing 1100 also largely determines the external shape of the electrical device 1000. In this embodiment, the external shape of the housing 1100 is not explicitly limited. In practical applications, those skilled in the art can choose according to specific needs, as long as the requirements are met. For example, the housing 1100 can be a triangular prism, cuboid, cylinder, or other three-dimensional structure.

[0026] The housing 1100 has an inner cavity 1110. Specifically, the aforementioned heat exchanger 1200 may be disposed in the inner cavity 1110.

[0027] Combination Figure 1 The inner cavity 1110 may include an inner air duct chamber 1111 and an outer air duct chamber 1112.

[0028] The internal air duct chamber 1111 is used to install the heating element 1600, which specifically refers to an electronic device that generates heat during use. The specific type, quantity, and installation location of the heating element 1600 are not limited here; in practical applications, those skilled in the art can determine them based on the type of electrical equipment 1000 and other relevant requirements. For example, the heating element 1600 can be a capacitor, a switch, etc.

[0029] The external air duct chamber 1112 may include a heat exchange chamber 1112A, through which a heat dissipation airflow passes. Internal air duct chambers 1111 may be provided on both sides of the heat exchange chamber 1112A along the first direction X. A first partition 1300 and a second partition 1400 are respectively provided between the heat exchange chamber 1112A and its two adjacent internal air duct chambers 1111 along the first direction X. (Refer to...) Figure 1The orientation and positional relationship in the heat exchanger 1200 can be defined as follows: the first direction X can be the length direction of the heat exchanger 1200; the inner air duct chamber 1111 can include two chambers; the two inner air duct chambers 1111 can be located on the left and right sides of the heat exchange cavity 1112A respectively; the aforementioned first partition 1300 can be provided between the inner air duct chamber 1111 on the right side and the heat exchange cavity 1112A; and the aforementioned second partition 1400 can be provided between the inner air duct chamber 1111 on the left side and the heat exchange cavity 1112A.

[0030] The first partition 1300 may be provided with a first connecting port 1310, and the second partition 1400 may be provided with a second connecting port 1410. A heat exchanger 1200 may be installed on the first partition 1300 and the second partition 1400 to seal the first connecting port 1310 and the second connecting port 1410. The heat exchanger 1200 may form a first heat exchange channel and a second heat exchange channel that are isolated from each other. The first heat exchange channel may extend along a first direction X, and the second heat exchange channel may extend along a second direction Y. The first direction X and the second direction Y may intersect, that is, they may form an angle, such as 90 degrees. The first heat exchange channel can connect the two inner air duct chambers 1111 on both sides of the heat exchange cavity 1112A, while the second heat exchange channel can be connected to the heat exchange cavity 1112A. In this way, heat exchange can be realized between the heat dissipation airflow in the heat exchange cavity 1112A and the hot airflow in the inner air duct chamber 1111, thereby achieving effective heat dissipation for the heat-generating device 1600 in the inner air duct chamber 1111.

[0031] The electrical equipment 1000 may further include a support plate 1500, which may be disposed within the heat exchange chamber 1112A. There may be two support plates 1500, which may be arranged alternately along a third direction Z. The third direction Z may intersect with either the first direction X or the second direction Y, i.e., the third direction Z may form an angle with either the first direction X or the second direction Y, such as 90 degrees. At least one of the housing 1100, the first partition, and the second partition may be connected to the support plate 1500 to achieve installation and fixation of the support plate 1500. The support plate 1500 supports the heat exchanger 1200, thereby improving the installation reliability of the heat exchanger 1200.

[0032] Please continue to refer to this. Figure 1 The external air duct chamber 1112 may further include an air intake chamber 1112B, which may be connected to the heat exchange chamber 1112A. The air intake chamber 1112B is used to introduce heat dissipation airflow, which can then be guided into the heat exchange chamber 1112A for heat exchange with the hot airflow in the internal air duct chamber 1111.

[0033] In practical applications, the electrical equipment 1000 may also include an air supply device, such as a fan. The air supply device may be installed inside the air intake chamber 1112B, or it may be installed in other locations. In short, the air supply device can provide cooling airflow to the air intake chamber 1112B.

[0034] It is understood that the above-described implementation of setting the number of heat exchange chambers 1112A to one and the number of inner air duct chambers 1111 to two is merely an exemplary description of the embodiments of this application in conjunction with the accompanying drawings. This should not be construed as limiting the scope of implementation of the electrical equipment 1000 provided in the embodiments of this application. Under the condition of satisfying the function, the number of heat exchange chambers 1112A and inner air duct chambers 1111 can also be set to other numbers. For example, the number of inner air duct chambers 1111 can be three, and the three inner air duct chambers 1111 can be arranged at intervals along the first direction X. A heat exchange chamber 1112A can be provided between two adjacent inner air duct chambers 1111 along the first direction X, that is, the number of heat exchange chambers 1112A can be two.

[0035] Please refer to Figures 3-9 , Figure 3 This is a schematic diagram of the structure of a heat exchanger provided in an embodiment of this application from one perspective; Figure 4 for Figure 3 A partial enlarged view of the connection between the first connecting end, the first sealing component, and the limiting component; Figure 5 for Figure 4 Cross-sectional view; Figure 6 This is a schematic diagram of the structure of a heat exchanger provided in an embodiment of this application from another perspective; Figure 7 This is a schematic diagram of the structure of a heat exchanger provided in an embodiment of this application from another perspective; Figure 8 for Figure 7 A partial enlarged view of the connection between the second connecting end, the second sealing component, and the edge protective plate; Figure 9 This is a cross-sectional view of the connection between the second connecting end and the second sealing component.

[0036] like Figure 3 , Figure 6 and Figure 7 As shown, this application embodiment provides a heat exchanger 1200, including an exchanger body 1210, a first connecting end 1220, a second connecting end 1230, a first sealing component 1240, and a second sealing component 1250.

[0037] The heat exchanger body 1210 is the main structure of the heat exchanger 1200 and is mainly used to realize the heat exchange function of the heat exchanger 1200.

[0038] The heat exchanger body 1210 may include at least two heat exchange tubes 1211. The heat exchange tubes 1211 may extend along a first direction X, and the aforementioned first heat exchange channel 1210A is formed inside the heat exchange tubes 1211. The heat exchange tubes 1211 may be arranged at intervals along a third direction Z; a second heat exchange channel 1210B is formed between two adjacent heat exchange tubes 1211 along the third direction Z. Specifically, the heat exchange tubes 1211 may be flat tubes, and the flattening direction of the flat tube is the third direction Z.

[0039] The heat exchanger body 1210 may also include heat exchange fins 1212, which may be disposed in at least one of the first heat exchange channel 1210A and the second heat exchange channel 1210B to increase the heat exchange area.

[0040] The first connecting end 1220 and the second connecting end 1230 are respectively connected to the two ends of the switch body 1210 along the first direction X. The first connecting end 1220 is provided with a connecting structure 1221, which is used for connecting and fixing the first connecting end 1220. A first sealing member 1240 may be provided on the side of the first connecting end 1220 facing the second connecting end 1230. A second sealing member 1250 is provided on the side of the second connecting end 1230 away from the first connecting end 1220.

[0041] During installation, the second connecting end 1230 and the heat exchanger body 1210 can be controlled to be inserted into the heat exchange chamber 1112A along the first connecting port 1310. The second connecting end 1230 can abut against the second partition 1400 through the second sealing member 1250, and the second sealing member 1250 can be arranged around the second connecting port 1410 to achieve a sealing arrangement between the second connecting end 1230 and the second partition 1400. The first connecting end 1220 can be connected and fixed to the first partition 1300 through the connecting structure 1221 to achieve the installation and fixation of the entire heat exchanger 1200. The first sealing member 1240 can be arranged between the first partition 1300 and the first connecting end 1220 to achieve a sealing arrangement between the first connecting end 1220 and the first partition 1300.

[0042] As can be seen, when installing the heat exchanger 1200 provided in this application embodiment, it is only necessary to control the heat exchanger body 1210 and the second connection end 1230 to be plugged in, and then control the connection structure 1221 of the first connection end 1220 and the first partition 1300 to be connected and fixed. The installation process is relatively simple, and correspondingly, the disassembly process is also relatively simple, which is conducive to improving the assembly and maintenance efficiency of the electrical equipment 1000.

[0043] In some implementations, such as Figure 4 and Figure 5 As shown, the connection structure 1221 can be a connection hole 1221A, and the first connection end 1220 is configured to be connected and fixed through the connection hole 1221A.

[0044] In one embodiment, the first partition 1300 may be provided with a stud, which can be inserted into the connecting hole 1221A, and then connected to the stud by a nut. When the nut is tightened, the nut can press the first connecting end 1220, thereby realizing the connection and fixation between the first connecting end 1220 and the first partition 1300.

[0045] In another embodiment, the first partition 1300 may also be provided with a connecting hole 1221A. During actual installation, the connecting hole 1221A of the first partition 1300 and the connecting hole 1221A of the first connecting end 1220 can be aligned. The electrical equipment 1000 may also include bolts and nuts, with the bolts passing through the two connecting holes 1221A and connected to the nuts. This also achieves the connection and fixation between the first connecting end 1220 and the first partition 1300.

[0046] In another embodiment, the aforementioned connecting hole 1221A can also be a snap-fit ​​hole. In this case, the first partition 1300 can be provided with a snap-fit ​​post, which can cooperate with the snap-fit ​​hole to achieve snap-fit ​​fixation of the first connecting end 1220 and the first partition 1300.

[0047] It can be seen that, in addition to the above-mentioned implementation of setting the connection hole 1221A in the connection structure 1221, in some other implementations of the embodiments of this application, the connection structure 1221 can also adopt other structural forms, as long as they can meet the relevant requirements such as the reliability of the connection. For example, the connection hole 1221A can be set in the first partition 1300. In this case, the connection structure 1221 can be a stud, a locking stud, etc.

[0048] In some implementations, such as Figure 5 and Figure 6 As shown, the heat exchanger 1200 may also include a reinforcing plate 1260.

[0049] A reinforcing plate 1260 can be installed on the first connecting end 1220 to reinforce it, reducing the possibility of damage during connection and fixing. In other words, the reinforcing plate 1260 extends the service life of the heat exchanger 1200. After reinforcement by the reinforcing plate 1260, the first connecting end 1220 is less prone to deformation, resulting in better compression of the first sealing component 1250 and improved sealing reliability.

[0050] The reinforcing plate 1260 may be provided with a first clearance structure 1261, which is configured to avoid the connecting structure 1221, so as to reduce the impact on the normal installation of the first connecting end 1220 caused by the setting of the reinforcing plate 1260.

[0051] Here, the embodiments of this application do not limit the specific structural form of the first avoidance structure 1261 described above. In practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use. For example, the first avoidance structure 1261 can be a circumferentially (around the direction of the first direction X) closed through hole, combined with Figure 5 and Figure 6 The shape and size of the through hole can be exactly the same as those of the connecting hole 1221A; or, in some modified designs, at least one of the shape and size of the through hole can be different from those of the connecting hole 1221A, as long as it does not affect its avoidance effect. For example, the first avoidance structure 1261 can also be a circumferentially non-closed groove, which is also feasible.

[0052] It is understood that the first avoidance structure 1261 is not a necessary structure. In some other implementations of this application, the reinforcing plate 1260 can also avoid the connecting structure 1221 as a whole. That is, the reinforcing plate 1260 can be installed at a position that does not interfere with the connecting structure 1221, which is also feasible.

[0053] The aforementioned reinforcing plate 1260 can be an integral ring plate. Alternatively, the aforementioned reinforcing plate 1260 can also include multiple sub-plates, each of which can be installed in the area of ​​the first connecting end 1220 where the connecting structure 1221 is provided, so as to provide targeted reinforcement to the area of ​​the first connecting end 1220 where the connecting structure 1221 is provided, which is also feasible.

[0054] In addition, in some other implementations of the embodiments of this application, the reinforcing plate 1260 and the first connecting end 1220 can also be integrally formed as a single structure, which is also feasible.

[0055] In some implementations, such as Figure 3 and Figure 4 As shown, the heat exchanger 1200 may also include a limiting member 1270.

[0056] The limiting member 1270 can be disposed on the side of the first connecting end 1220 facing the second connecting end 1230. Figure 5 A portion of the first sealing member 1240 may protrude from the limiting member 1270 along the first direction X toward the side near the second connecting end 1230.

[0057] With this configuration, when connecting the first connecting end 1220 and the first partition 1300, the first sealing member 1240 can contact the first partition 1300 before the limiting member 1270, so that the first sealing member 1240 can be compressed by the first partition 1300, thereby achieving a sealing arrangement between the first partition 1300 and the first connecting end 1220; then, the limiting member 1270 can abut against the first partition 1300 to limit further compression of the first sealing member 1240, which can reduce the risk of crushing damage to the first sealing member 1240.

[0058] In other words, the setting of the aforementioned limiting component 1270 can control the amount of compression deformation of the first sealing component 1240, which can improve the reliability of the seal and reduce the risk of damage to the first sealing component 1240, thus greatly extending the service life of the first sealing component 1240.

[0059] The aforementioned limiting component 1270 may be provided with a second clearance structure 1271. The second clearance structure 1271 can avoid the connecting structure 1221, reducing the impact on the normal installation of the first connecting end 1220 caused by the setting of the limiting component 1270. The specific structural form of the second clearance structure 1271 can be consistent with the aforementioned first clearance structure 1261, and will not be described again here. It can be seen that the aforementioned second clearance structure 1271 is not a necessary component. In some other implementations of the embodiments of this application, the limiting component 1270 can also completely avoid the connecting structure 1221, that is, the limiting component 1270 can be installed in a position that does not interfere with the connecting structure 1221, which is also feasible.

[0060] The aforementioned limiting component 1270 can be a one-piece annular plate. Alternatively, the aforementioned limiting component 1270 can also include multiple sub-plates, which can be arranged at intervals around the first direction X, which is also feasible.

[0061] In addition, in some other implementations of the embodiments of this application, the aforementioned limiting component 1270 and the first connecting end 1220 can also be an integrally formed structure, which is also feasible.

[0062] In some implementations, such as Figure 6 and Figure 7 As shown, the heat exchanger 1200 may also include a side guard plate 1280.

[0063] The aforementioned side protection plate 1280 is disposed on at least one side of the switch body 1210 along the third direction Z to protect the switch body 1210 and reduce the possibility of collision damage to the switch body 1210 during transportation, installation, etc. During specific assembly, at least one of the switch body 1210, the first connecting end 1220, and the second connecting end 1230 can be connected to the side protection plate 1280 to achieve the installation and fixation of the side protection plate 1280.

[0064] Combination Figure 8 The edge protection plate 1280 includes a main body 1281 and a flanged part 1282.

[0065] The main body 1281 may be located on the side of the exchanger body 1210 along the third direction Z to protect the exchanger body 1210 along the third direction Z. The flange 1282 may be located on the side of the exchanger body 1210 along the second direction Y. A portion of the flange 1282 may protrude from the second connection end 1230 along the second direction Y in a direction away from the exchanger body 1210, or the side of the flange 1282 away from the exchanger body 1210 along the second direction Y may be flush with the second connection end 1230; thus, the heat exchanger 1200 provided in this embodiment can be supported and assembled by the flange 1282, which can reduce the possibility of damage to the exchanger body 1210 during installation and use.

[0066] Specifically, the aforementioned flange 1282 can be used to abut against the aforementioned support plate 1500. During installation and disassembly, the flange 1282 can slide along the support plate 1500, guiding the displacement of the heat exchanger 1200 within the heat exchange chamber 1112A. After installation, the support plate 1500 can support the heat exchanger 1200 via the flange 1282, improving the installation reliability of the heat exchanger 1200.

[0067] In some implementations, such as Figure 9 As shown, the second sealing component 1250 may include a connecting portion 1251 and a deformable portion 1252.

[0068] The connecting portion 1251 may be provided with a connecting groove 1251A, and the second connecting end 1230 may be provided with a connecting plate 1231. The connecting plate 1231 can be inserted into the connecting groove 1251A, thereby enabling the connection and fixation of the second sealing component 1250 and the second connecting end 1230. It is understood that there is an interference fit between the connecting plate 1231 and the connecting portion 1251, making it difficult for the two to separate after the connecting plate 1231 is inserted into the connecting portion 1251.

[0069] The deformable portion 1252 is located on one side of the connecting portion 1251 along the first direction X. The deformable portion 1252 has a cavity 1252A, which allows the deformable portion 1252 to be deformed relatively easily. In actual assembly, the second sealing member 1250 can be sealed between the second partition 1400 by the deformable portion 1252 abutting against the second partition 1400.

[0070] The connecting plate 1231 has a large surface 1231A, which specifically refers to the surface with the largest area in the connecting plate 1231, such as... Figure 9 The upper or lower surface of the connecting plate 1231; the large surface 1231A can be perpendicular to the normal of the connecting plate 1231. The large surface 1231A can also form an angle with the first direction X. For example, see... Figure 9 The included angle can be 90 degrees. For example, the included angle can also be 30 degrees, 60 degrees, or other angle values, which are not limited here. Alternatively, the large surface 1231A of the connecting plate 1231 can be parallel to the first direction X. In this case, the connecting part 1251 is inserted into the connecting plate 1231 along the first direction X, which is also feasible.

[0071] The first sealing component 1240 may have the same structure as the aforementioned second sealing component 1250. Alternatively, the first sealing component 1240 may be a rubber strip, such as an ethylene propylene diene monomer (EPDM) rubber strip, the cross-section of which may be rectangular, etc.

[0072] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
