Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a manifold assembly, a heat exchanger, and an air conditioner. Background Technology

[0002] When microchannel heat exchangers arrange flat tubes in multiple rows, spacers are typically welded between the upper and lower flat tubes to prevent heat exchange between the rows and avoid heat loss. However, welding spacers between the upper and lower flat tubes results in numerous weld points, which can easily lead to poor brazing between the spacers and the manifold. Furthermore, welding multiple spacers complicates the assembly process of the manifold and reduces processing efficiency. Utility Model Content

[0003] This utility model provides a manifold assembly, a heat exchanger, and an air conditioner to solve the technical problem of uneven refrigerant distribution in the upper and lower heat exchangers of the manifold assembly in a parallel flow heat exchanger, which leads to a decrease in the overall heat exchange performance of the heat exchanger.

[0004] This utility model provides a flow collector assembly for a heat exchanger, the heat exchanger including a plurality of heat exchange tubes arranged along a first direction, and the flow collector assembly including a partition plate and a fixing plate. The partition plate includes a plurality of baffles and a base plate, with a first receiving groove formed between adjacent baffles. The baffles and the base plate are integrally formed, and each baffle has the same thickness along the first direction. The partition plate is disposed on the fixing plate, and the fixing plate seals the first receiving groove to form a communicating channel. The fixing plate is used to fix the plurality of heat exchange tubes, and at least two ends of the heat exchange tubes are inserted into a corresponding communicating channel.

[0005] Thus, by integrally molding the baffles on the baffles, the heat exchange tubes of adjacent rows can be separated by the baffles to avoid heat exchange. Furthermore, the baffles do not need to be installed between adjacent rows of heat exchange tubes by welding, thereby reducing the assembly process of the manifold, improving processing efficiency, and by setting the baffles to the same thickness, the production process can be simplified and maintenance can be made easier.

[0006] In some embodiments, the current collection assembly includes a plurality of the partitions connected in sequence.

[0007] Thus, by setting multiple baffles in the current collector assembly and connecting them in sequence, it is possible to flexibly adapt to different sizes and layouts of the fixed plate, ensuring the compactness and rationality of the internal structure of the current collector assembly. Furthermore, the multi-segment connected baffles can effectively disperse the stress generated by the current collector assembly during operation and reduce the amount of deformation generated by the baffles when working in high-temperature environments, thereby improving the overall structural strength and stability of the current collector assembly.

[0008] In some embodiments, the connecting channel includes a first connecting channel and a second connecting channel, wherein the first connecting channel is away from the connection point of two adjacent partitions, and the second connecting channel is close to the connection point of two adjacent partitions, and the height of the second connecting channel is less than the height of the first connecting channel along the first direction.

[0009] Thus, by designing the size of the second connecting channel near the connection of two adjacent partitions to be smaller than the size of the first connecting channel far from the connection of two adjacent partitions, the spacing between each row of heat exchange tubes can be adapted when the two adjacent partitions are connected, which is beneficial for fixing the heat exchange tubes and for the flow of refrigerant in the connecting channel.

[0010] In some embodiments, along the first direction, the size of the heat exchange tube is greater than or equal to 1 mm and less than or equal to 2.5 mm, the size of the first connecting channel is greater than or equal to 2 mm and less than or equal to 3.5 mm, and the size of the second connecting channel is greater than or equal to 1 mm and less than or equal to 2 mm.

[0011] Thus, by setting the size of the heat exchange tube to be greater than or equal to 1 mm and less than or equal to 2.5 mm, setting the size of the first connecting channel to be greater than or equal to 2 mm and less than or equal to 3.5 mm, and setting the size of the second connecting channel to be greater than or equal to 1 mm and less than or equal to 2 mm, the heat exchange tube is prevented from being blocked due to the connecting channel being too small.

[0012] In some embodiments, the plurality of heat exchange tubes are arranged at equal intervals along the first direction.

[0013] In this way, by arranging multiple heat exchange tubes at equal intervals, it can be ensured that the refrigerant is evenly distributed inside the heat exchange tubes, avoiding uneven heat exchange in certain areas, so that each heat exchange tube can give full play to its heat exchange function and improve the overall heat exchange efficiency.

[0014] In some embodiments, the partition includes a recess and a convex portion, the recess and the convex portion being clearance-fitted and disposed at opposite ends of the partition, and adjacent partitions being connected by the recess and the convex portion.

[0015] Thus, by setting recesses and protrusions on the partitions, adjacent partitions can be fixed together, and the recesses and protrusions can play a positioning role, avoiding incorrect connection of the partitions.

[0016] In some embodiments, the thickness of the partition is greater than or equal to 1 mm and less than or equal to 3 mm, the recess is recessed into the end face of the partition, and the convex is protruding from the end face of the partition. When adjacent partitions are connected, the recess and the convex cooperate to make the adjacent partitions abut against each other.

[0017] By setting the thickness of the partitions to be uniform, standardized molds and processes can be used to produce them, thereby simplifying the production process, reducing production costs, and improving production efficiency and product quality. Furthermore, it allows for precise connection between the recesses and convex parts, thus improving the accuracy of the partition connections.

[0018] In some embodiments, the fixing plate is provided with a second receiving groove and a fixing hole, the partition is disposed in the second receiving groove, the inner wall of the second receiving groove seals the first receiving groove to form the communicating channel, and one end of at least two of the heat exchange tubes passes through the fixing hole and extends into the communicating channel.

[0019] Thus, by providing a second receiving groove and a fixing hole on the fixing plate, the fixing plate can provide an installation position for the heat exchange tube and the partition plate, and the inner wall of the second receiving groove can seal the first receiving groove, thereby forming a connecting channel so that the heat exchange tube can perform heat exchange circulation.

[0020] In some embodiments, the dimension of the portion of the heat exchange tube extending into the communication channel is less than or equal to half the dimension of the communication channel along the length of the heat exchange tube.

[0021] Thus, excessively long heat exchange tubes can prevent uneven refrigerant flow within the connecting channel, which would negatively impact heat exchange efficiency. Furthermore, excessively long heat exchange tubes can prevent increased resistance to refrigerant flow within the connecting channel, thus avoiding a decrease in refrigerant velocity. Additionally, excessively long heat exchange tubes extending into the connecting channel can prevent increased pressure drop during heat exchange, thereby reducing energy consumption.

[0022] In some embodiments, the minimum distance between the heat exchange tube extending into the communication channel and the partition is greater than or equal to 0.5 mm.

[0023] In this way, by maintaining a distance between the heat exchange tubes extending into the connecting channel and the baffles, weld blockage of the heat exchange tubes can be avoided when brazing the heat exchange tubes and the fixed plate.

[0024] In some embodiments, the fixing plate has fixing parts on both sides, and when the partition extends into the second receiving groove, the fixing parts abut against the partition to fix the partition to the fixing plate.

[0025] Thus, by providing a fixing part on the fixing plate, the fixing part can cooperate with the bottom plate when the partition extends into the second receiving groove, thereby fixing the fixing part and the partition and improving the structural strength of the current collection assembly.

[0042] Please see Figures 1 to 5 This utility model provides a flow collector 300 for a heat exchanger 1000. The heat exchanger 1000 includes a plurality of heat exchange tubes 100 arranged along a first direction. The flow collector 300 includes a partition plate 310 and a fixing plate 320. The partition plate 310 includes a plurality of partitions 311 and a base plate 312. A first receiving groove 313 is formed between adjacent partitions 311. The partitions 311 and the base plate 312 are integrally formed, and each partition 311 has the same thickness along the first direction. The partition plate 310 is disposed on the fixing plate 320. The fixing plate 320 seals the first receiving groove 313 to form a communicating channel 330. The fixing plate 320 is used to fix the plurality of heat exchange tubes 100 and to insert one end of at least two heat exchange tubes 100 into a corresponding communicating channel 330.

[0043] Thus, by integrally forming the partition plate 311 with the partition plate 310, the heat exchange tubes 100 in two adjacent rows can be separated by the partition plate 311 to avoid heat exchange. Furthermore, the partition plate 311 does not need to be welded between adjacent rows of heat exchange tubes 100, thereby reducing the assembly process of the manifold, improving processing efficiency, and simplifying the production process and facilitating maintenance by setting the partition plate 311 to the same thickness.

[0044] The heat exchanger 1000 is used in an air conditioner (not shown in the attached diagram). The heat exchanger 1000 can transfer heat from the refrigerant to the external environment or absorb heat from the external environment, thereby achieving cooling or heating in the air conditioner. The heat exchanger 1000 can be a parallel flow heat exchanger 1000, which includes a manifold assembly 300, heat exchange tubes 100, and fins. By setting manifold assemblies 300 at both ends of the heat exchange tubes 100, and using baffles 310 on the manifold assemblies 300 to form a series channel, the refrigerant enters the liquid collection assembly through a pipe joint, then flows into the heat exchange tubes 100, flows parallel to the opposite liquid collection assembly, and finally flows out through another pipe joint.

[0045] Specifically, the manifold 300 can be used in the heat exchanger 1000 to uniformly distribute the refrigerant into each heat exchange tube 100. When the heat exchanger 1000 is used as an evaporator or condenser, the manifold 300 ensures uniform refrigerant flow distribution within the heat exchange tubes 100, thereby improving the overall heat exchange performance of the heat exchanger 1000 and helping to avoid localized overheating or undercooling of the heat exchanger 1000, thus improving heat exchange efficiency.

[0046] The heat exchanger 1000 includes multiple heat exchange tubes 100, which can be arranged in multiple rows along a first direction, which can be the direction of gravity. The multiple heat exchange tubes 100 can be arranged in multiple rows of two tubes each, with the two tubes in each row connected in a manifold 300, allowing refrigerant in one heat exchange tube 100 to flow into the other. The multiple rows of heat exchange tubes 100 can be arranged at equal intervals along the direction of gravity. By arranging the multiple heat exchange tubes 100 at equal intervals, the refrigerant can be evenly distributed within the heat exchange tubes 100, avoiding uneven heat exchange in certain areas, allowing each heat exchange tube 100 to fully perform its heat exchange function, and improving the overall heat exchange efficiency.

[0047] The current collector assembly 300 includes a baffle plate 310 and a fixing plate 320. Both the baffle plate 310 and the fixing plate 320 are made of metal. For example, the baffle plate 310 and the fixing plate 320 can be made of aluminum alloy. The baffle plate 310 includes multiple baffles 311 and a base plate 312. The multiple baffles 311 are disposed on the same base plate 312, and the multiple baffles 311 included on the baffle plate 310 have the same thickness, enabling the baffle plate 310 to be standardized and uniform, and allowing the baffles 311 and the base plate 312 to be manufactured using an integral molding process. For example, common casting methods for integral molding of baffles 311 and base plate 312 include sand casting, pressure casting, and gas pressure casting. For example, by injecting molten metal or alloy into a pre-made mold, and allowing it to solidify and cool, an integrally molded structure of baffles 311 and base plate 312 is formed.

[0048] The partition 311 and the base plate 312 can be integrally formed by forging. Common forging methods include free forging, die forging, and extrusion forging. For example, by heating the metal material to a temperature that is easy to deform, pressure is applied in a mold to plastically deform it into an integrally formed partition 311 and base plate 312.

[0049] The partition 311 and the base plate 312 can be integrally formed by plastic forming. For example, the partition 311 and the base plate 312 can be integrally formed by stretching, stamping, rolling and other processing of metal materials.

[0050] The spacer 311 and the base plate 312 can be integrally formed by laser melting. For example, the spacer 311 and the base plate 312 can be integrally formed by locally heating the material with a laser beam, melting it, and then controlling the deformation.

[0051] The integral molding structure of the partition 311 and the base plate 312 increases the connection strength between them, preventing loosening or detachment during use. Because the partition 311 and base plate 312 are integrally molded, the connection points are typically tighter, contributing to a better seal and preventing airflow leakage or the ingress of external impurities. The integral molding structure reduces the connection gaps between the partition 311 and base plate 312, thereby reducing resistance to refrigerant flow and allowing for smoother refrigerant flow. The integral molding structure also results in a cleaner and more aesthetically pleasing appearance, meeting the aesthetic requirements of modern air conditioning products. Furthermore, the integral molding process typically offers higher production efficiency, shortening production cycles and reducing production costs.

[0052] The adjacent partitions 311 are spaced apart from each other, thereby forming a first receiving groove 313. When the heat exchange tube 100 is fixed to the fixing part 323, the first receiving groove 313 can accommodate the heat exchange tube 100 and the refrigerant flowing out of the heat exchange tube 100.

[0053] When the partition plate 310 is fixed to the fixing plate 320, the inner wall of the fixing plate 320 can seal both ends of the first receiving groove 313, so that the first receiving groove 313 can form a connecting channel 330. The connecting channel 330 can be used to receive the refrigerant flowing out of the heat exchange tube 100. When multiple heat exchange tubes 100 are fixed to the fixing plate 320, at least two heat exchange tubes 100 can have one end inserted into a corresponding connecting channel 330. Thus, after the refrigerant flowing out of one of the two heat exchange tubes 100 enters the connecting channel 330, it can flow into the other heat exchange tube 100 and out of the connecting channel 330.

[0054] Please see Figure 2 and Figure 3 In some embodiments, the current collection assembly 300 includes a plurality of partitions 310 connected in sequence.

[0055] Thus, by setting multiple baffles 310 in the current collector 300, and connecting the multiple baffles 310 in sequence, it is possible to flexibly adapt to different sizes and layouts of the fixed plate 320, ensuring the compactness and rationality of the internal structure of the current collector 300. Moreover, the multi-segment connected baffles 310 can effectively disperse the stress generated by the current collector 300 during operation, and reduce the deformation of the baffles 310 when working in a high-temperature environment, thereby improving the overall structural strength and stability of the current collector 300.

[0056] Specifically, due to limitations in the size and manufacturing process of the fixing plate 320, the current collector assembly 300 needs to include multiple partitions 310, and adjacent partitions 310 can be connected to each other, so that the partitions 310 can correspond to the size of the fixing plate 320. For example, when the fixing member is 1 meter in size, the partitions 310 can be set to 3 partitions 310 according to the size of the fixing plate 320.

[0057] Therefore, dividing the baffle 310 into multiple connected segments simplifies the manufacturing process of the current collector assembly 300, helping to reduce production costs and improve production efficiency. Furthermore, the multi-segment design of the baffle 310 makes the installation and maintenance of the current collector assembly 300 more convenient, allowing for easier disassembly and reassembly when parts need to be replaced or repaired. Additionally, since the current collector assembly 300 needs to withstand certain pressure and temperature fluctuations during use, dividing the baffle 310 into multiple connected segments effectively disperses the pressure, reduces the stress on individual baffles 310, and extends the service life of the baffles 310.

[0058] Please see Figure 5 In some embodiments, the connecting channel 330 includes a first connecting channel 331 and a second connecting channel 332. The first connecting channel 331 is away from the connection point of two adjacent partitions 310, and the second connecting channel 332 is close to the connection point of two adjacent partitions 310. Along the first direction, the height of the second connecting channel 332 is less than the height of the first connecting channel 331.

[0059] Thus, by designing the size of the second connecting channel 332 near the connection of two adjacent partitions 310 to be smaller than the size of the first connecting channel 331 far from the connection of two adjacent partitions 310, the connection of two adjacent partitions 310 can be adapted to the spacing between each row of heat exchange tubes 100, which is beneficial to the fixation of the heat exchange tubes 100 and the flow of refrigerant in the connecting channel 330.

[0060] Specifically, since there are two partition plates 311 at the connection of the two partitions 310, the size of the connection is increased. Therefore, in order to keep the spacing between adjacent rows of heat exchange tubes 100 unchanged, the connecting channel 330 can be set as a first connecting channel 331 and a second connecting channel 332. The first connecting channel 331 can be set away from the connection of the two adjacent partitions 310, and the second connecting channel 332 can be set close to the connection of the two adjacent partitions 310. Furthermore, the size Y of the second connecting channel 332 is smaller than the size S of the first connecting channel 331 in the direction of gravity. Thus, it is not necessary to change the spacing between the two adjacent rows of heat exchange tubes 100. The heat exchange tubes 100 can be inserted into the corresponding first connecting channel 331 and second connecting channel 332 through the fixing holes 322. This can save costs and reduce the number of steps required to set multiple sizes when manufacturing the fixing holes 322 on the fixing plate 320.

[0061] Please see Figure 5 In some embodiments, along the first direction, the size of the heat exchange tube 100 is greater than or equal to 1 mm and less than or equal to 2.5 mm, the size of the first connecting channel 331 is greater than or equal to 2 mm and less than or equal to 3.5 mm, and the size of the second connecting channel 332 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0062] Thus, by setting the size of the heat exchange tube to be greater than or equal to 1 mm and less than or equal to 2.5 mm, setting the size of the first connecting channel to be greater than or equal to 2 mm and less than or equal to 3.5 mm, and setting the size of the second connecting channel to be greater than or equal to 1 mm and less than or equal to 2 mm, the heat exchange tube is prevented from being blocked due to the connecting channel being too small.

[0063] Specifically, the first direction can be the direction of gravity, so that the dimension P of the heat exchange tube 100 along the direction of gravity is greater than or equal to 1 mm and less than or equal to 2.5 mm. For example, the dimension P of the heat exchange tube 100 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm or any value between 1 mm and 2.5 mm.

[0064] The dimension S of the first connecting channel 331 is greater than or equal to 2 mm and less than or equal to 3.5 mm. For example, the dimension S of the first connecting channel 331 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm or any value between 2 mm and 3.5 mm.

[0065] The dimension Y of the second connecting channel 332 is greater than or equal to 1 mm and less than or equal to 2 mm. For example, the dimension Y of the second connecting channel 332 can be 1 mm, 1.2 mm, 1.5 mm, 2 mm or any value between 1 mm and 2 mm.

[0066] Please see Figure 2In some embodiments, the partition 310 includes a recess 314 and a protrusion 315, the recess 314 and the protrusion 315 are clearance-fitted and disposed at opposite ends of the partition 310, and adjacent partitions 310 are connected by the recess 314 and the protrusion 315.

[0067] Thus, by providing recesses 314 and protrusions 315 on the partition 310, adjacent partitions 310 can be fixed together, and the recesses 314 and protrusions 315 can play a positioning role to avoid incorrect connection of the partitions 310.

[0068] Specifically, the partition 310 is provided with a recess 314 and a protrusion 315. The recess 314 and the protrusion 315 are located at opposite ends of the same partition 310. The recess 314 and the protrusion 315 of the partition 310 are designed to be clearance fit, that is, the protrusion 315 can be easily inserted into the recess 314, but can maintain a certain stability and connection strength. Thus, when two adjacent partitions 310 are connected, the clearance fit between the recess 314 and the protrusion 315 enables the connection between the two adjacent partitions 310. The fact that the recess 314 and the protrusion 315 are located at opposite ends of the partition 310 ensures the connection stability and continuity between adjacent partitions 310, so that the partitions 310 can form an integral structure during assembly, improving the overall strength and stability.

[0069] The recess 314 and protrusion 315 of the baffle 310 are designed with a clearance fit, which allows the baffle 310 to adapt to thermal expansion or mechanical stress when the current collector assembly 300 is in operation, thereby improving the service life of the baffle 310. Through the clearance fit of the recess 314 and protrusion 315, a solid connection can be formed between two adjacent baffles 310, which helps to disperse and resist external pressure, thereby improving the strength of the entire structure.

[0070] The recessed portion 314 and protruding portion 315 of the partition 310 make the installation process simpler and more convenient. It also allows for easier disassembly and reassembly when maintenance or replacement of the partition 310 is required.

[0071] Please see Figure 2 and Figure 5 In some embodiments, the thickness of the partition 311 is greater than or equal to 1 mm and less than or equal to 3 mm. The recess 314 is recessed into the end face of the partition 311, and the protrusion 315 protrudes from the end face of the partition 311. When adjacent partitions 310 are connected, the recess 314 and the protrusion 315 cooperate to make the adjacent partitions 311 abut against each other.

[0072] Thus, by setting the thickness of the partition 311 to be the same, the partition 311 can be produced using standardized molds and processes, thereby simplifying the production process, reducing production costs, and improving production efficiency and product quality. Furthermore, it allows the recess 314 and the protrusion 315 to be accurately connected, thereby improving the accuracy of the partition 310 connection.

[0073] Specifically, the partition 310 includes multiple partition plates 311 of the same thickness, enabling the partition 310 to be standardized and uniform. This simplifies the production, installation, and maintenance process of the partition 310, as it eliminates the need to design different production molds, installation tools, and maintenance procedures for partition plates 311 of varying thicknesses. The standardization and uniformity of the partition 310 also improves its compatibility and interchangeability, making it easier to combine and replace different components.

[0074] Using spacers 311 of the same thickness during production simplifies the process and reduces production time and costs. This is because it eliminates the need for frequent mold changes or production line adjustments to accommodate spacers 311 of varying thicknesses. Furthermore, using spacers 311 of the same thickness reduces errors and waste during production, improving efficiency and product quality.

[0075] The thickness of the partition 311 is greater than or equal to 1 mm and less than or equal to 3 mm. For example, the thickness of the partition 310 can be 1 mm, 2 mm, 3 mm or any value between 1 mm and 3 mm.

[0076] The recess 314 can be recessed into one end face of the partition 311, and the convex part 315 can protrude from the other end face of the partition 311. When adjacent partitions 310 are connected, the recess 314 and the convex part 315 can be fitted with a gap, so that adjacent partitions 311 can abut against each other, and adjacent partitions 310 can be connected.

[0077] Please see Figure 4 and Figure 5 In some embodiments, the fixing plate 320 is provided with a second receiving groove 321 and a fixing hole 322, the partition plate 310 is provided in the second receiving groove 321, the inner wall of the second receiving groove 321 seals the first receiving groove 313 to form a communicating channel 330, and one end of at least two heat exchange tubes 100 passes through the fixing hole 322 and extends into the communicating channel 330.

[0078] Thus, by providing a second receiving groove 321 and a fixing hole 322 on the fixing plate 320, the fixing plate 320 can provide an installation position for the heat exchange tube 100 and the partition plate 310, and the inner wall of the second receiving groove 321 can seal the first receiving groove 313, thereby forming a connecting channel 330, so that the heat exchange tube 100 can perform heat exchange circulation.

[0079] Specifically, the fixing plate 320 is provided with a second receiving groove 321, the size of which can be adapted to the size of the partition plate 310, so that the second receiving groove 321 can accommodate the partition plate 310. Furthermore, when the partition plate 310 extends into the second receiving groove 321, the partition plate 311 can be connected to the bottom surface of the second receiving groove 321, and both ends of the first receiving groove 313 can be sealed by the side wall of the second receiving groove 321, so that the first receiving groove 313 can be sealed to form a communicating channel 330.

[0080] A fixing hole 322 is provided on the fixing plate 320. The fixing hole 322 can be made by punching, which reduces costs and increases efficiency compared to drilling. The size of the fixing hole 322 is adapted to the size of the heat exchange tube 100, so that the heat exchange tube 100 can pass through the fixing hole 322 and extend into the connecting channel 330. The heat exchange tube 100 and the fixing hole 322 can be connected by brazing, so that the fixing hole 322 and the heat exchange tube 100 can be sealed, and the connecting channel 330 can also be sealed, allowing refrigerant to flow from one heat exchange tube 100 to the other.

[0081] Please see Figure 5 In some embodiments, the size of the portion of the heat exchange tube 100 extending into the communication channel 330 is less than or equal to half the size of the communication channel 330 along the length of the heat exchange tube 100.

[0082] Thus, an excessively long heat exchange tube 100 can prevent uneven flow of the refrigerant within the connecting channel 330, which would negatively impact heat exchange efficiency. It also prevents the heat exchange tube 100 from increasing resistance to refrigerant flow within the connecting channel 330, thus avoiding a decrease in refrigerant velocity. Furthermore, it prevents the excessive length of the heat exchange tube 100 extending into the connecting channel 330 from increasing the pressure drop of the fluid during heat exchange, thereby increasing energy consumption.

[0083] Specifically, when the heat exchange tube 100 passes through the fixing hole 322 to extend into the connecting channel 330, in order to avoid the heat exchange tube 100 being too long and causing uneven flow of refrigerant in the connecting channel 330, thus affecting the heat exchange effect, it is necessary to limit the dimension B of the heat exchange tube 100 extending into the connecting channel 330. For example, the dimension B of the portion of the heat exchange tube 100 extending into the connecting channel 330 should be less than or equal to 1 / 2 of the dimension T of the connecting channel 330 along the length direction of the heat exchange tube 100, that is, the portion of the heat exchange tube 100 extending into the connecting channel 330 should not exceed half of the connecting channel 330.

[0084] When the refrigerant flows through the heat exchange tube 100, a pressure drop will occur. If the dimension B of the heat exchange tube 100 extending into the connecting channel 330 is too long, the pressure drop of the refrigerant in the connecting channel 330 will increase, thereby increasing the energy consumption of the manifold 300.

[0085] Under high temperature and high pressure operating conditions, the heat exchange tube 100 may expand or generate thermal stress due to heat. When the length B of the heat exchange tube 100 extending into the connecting channel 330 is too long, it will increase the concentration of thermal stress, thereby causing the heat exchange tube 100 to deform or crack, reducing its service life. Furthermore, an excessively long heat exchange tube 100 may also increase the vibration and noise level of the heat exchange tube 100, affecting the stability and reliability of the current collector assembly 300.

[0086] Please see Figure 5 In some embodiments, the minimum distance between the heat exchange tube 100 extending into the communication channel 330 and the partition 311 is greater than or equal to 0.5 mm.

[0087] Thus, by maintaining a distance between the heat exchange tube 100 extending into the communication channel 330 and the partition 311, it is possible to prevent the heat exchange tube 100 from becoming blocked during the brazing of the heat exchange tube 100 and the fixing plate 320.

[0088] Specifically, when the partition plate 310 extends into the second receiving groove 321, the distance between the partition plate 311 and the fixing hole 322 needs to be determined so that the minimum distance L between the heat exchange tube 100 passing through the fixing hole 322 and extending into the connecting channel 330 and the partition plate 311 is greater than or equal to 0.5 mm. That is, the portion of the heat exchange tube 100 extending into the connecting channel 330 needs to have a minimum distance greater than L or equal to 0.5 mm between it and two adjacent partition plates 311. In this way, when brazing the heat exchange tube 100 and the fixing plate 320, it is possible to avoid the solder from clogging the opening of the heat exchange tube 100, thereby affecting the inflow and outflow of the refrigerant from the heat exchange tube 100.

[0089] Please see Figure 2 and Figure 4 In some embodiments, fixing portions 323 are provided on both sides of the fixing plate 320. When the partition plate 310 extends into the second receiving groove 321, the fixing portions 323 abut against the partition plate 310 to fix the partition plate 310 to the fixing plate 320.

[0090] Thus, by providing a fixing part 323 on the fixing plate 320, when the partition plate 310 extends into the second receiving groove 321, the fixing part 323 can cooperate with the bottom plate 312 to fix the fixing part 323 and the partition plate 310, thereby improving the structural strength of the current collection assembly 300.

[0091] Specifically, after the partition plate 310 extends into the second receiving groove 321, the partition plate 310 needs to be fixed to the fixing plate 320 to prevent refrigerant leakage caused by a gap between the partition plate 310 and the fixing plate 320 when the refrigerant flows through the manifold 300. Thus, by providing fixing parts 323 on both sides of the fixing plate 320, the fixing parts 323 can abut against the bottom plate 312 of the partition plate 310, and the partition plate 311 can squeeze the fixing plate 320, thereby fixing the partition plate 310 to the fixing plate 320.

[0092] It should be noted that the fixing part 323 abuts against the base plate 312 by bending the fixing part 323 through a sheet metal bending process. For example, the fixing plate 320 is placed into the mold and bent using a bending machine, so that the fixing part 323 abuts against the base plate 312.
