Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and more specifically, to a heat exchanger. Background Technology

[0002] Currently, the main function of the manifold in a heat exchanger is to evenly distribute the fluid entering the heat exchanger to each heat exchange tube or channel, and to effectively collect the fluid leaving the heat exchanger, ensuring uniform fluid flow distribution throughout the heat exchanger and thus improving heat exchange efficiency. To evenly distribute the fluid, the manifold is equipped with baffles. However, the multiple baffles used to divide the fluid inside the manifold are usually integrally molded with the manifold body, making the internal structure of the manifold complex and the overall manufacturing difficult. Furthermore, the integral molding design of the manifold body and the baffles requires more precise machining technology, high precision requirements for manufacturing equipment and processes, and high operational difficulty, resulting in higher processing costs, longer processing time, and low batch processing efficiency, which cannot meet the actual demand for large-scale and high-efficiency manifold production.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0042] like Figures 1 to 14 As shown, an embodiment of this utility model provides a heat exchanger, including a manifold structure. The manifold structure includes a manifold body 10 and multiple turbulence-inducing columns 20. The manifold body 10 has a liquid cavity 11 inside, and the side wall of the manifold body 10 also has multiple mating holes 12, which are disposed through the side wall. The multiple turbulence-inducing columns 20 are mated one-to-one with the multiple mating holes 12. A portion of each turbulence-inducing column 20 extends into the liquid cavity 11 through the corresponding mating hole 12 to induce turbulence. The turbulence-inducing columns 20 are fixed to the manifold body 10 by welding or interference fit, and the mating holes 12 are sealed.

[0043] This invention features a separate structure for the collector body 10 and multiple baffle columns 20, which are subsequently sealed and fixed together by welding or other methods. This allows the collector body 10 and the baffle columns 20 to be processed and formed separately, simplifying the internal structure of the collector body 10, reducing the overall manufacturing difficulty of the collector tube, and eliminating the need for particularly precise machining techniques when forming the collector body 10 and baffle columns 20. This reduces the precision requirements of manufacturing equipment and processes, simplifies the processing operations for workers, effectively reduces processing costs and time, improves batch processing efficiency and product quality stability, and thus meets the actual needs of large-scale and high-efficiency collector tube production. In addition, the separate design of the collector body 10 and baffle columns 20 also facilitates subsequent maintenance and upgrades of the collector tube product. This invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of high manufacturing difficulty, high processing cost, and long processing time in the existing heat exchanger collector tubes, making it unsuitable for efficient mass production. It is suitable for large-scale promotion and use.

[0044] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 13 and Figure 14As shown, the manifold structure has mutually perpendicular length, width, and height directions; the extension direction of the mating hole 12 is parallel to the height direction; the manifold structure also includes a partition plate 30, and the surface of the manifold structure with the mating hole 12 also has a first positioning hole 13, which communicates with the liquid chamber 11, and the extension direction of the first positioning hole 13 is parallel to the extension direction of the mating hole 12; the inner wall of the liquid chamber 11 has two correspondingly arranged limiting grooves 14; the partition plate 30 is located inside the liquid chamber 11, and both ends of the partition plate 30 along the width direction are respectively arranged in a limiting groove 14 and are limited and matched with the inner wall of the limiting groove 14; wherein, one end of the partition plate 30 along the height direction is sealed and matched with the first positioning hole 13, and the partition plate 30 divides the liquid chamber 11 into two chambers, namely the first chamber 111 and the second chamber 112, and a part of the turbulence column 20 is located in the second chamber 112.

[0045] By introducing the partition plate 30 and the limiting groove 14, the liquid chamber 11 is effectively divided, forming an independent first chamber 111 and a second chamber 112, thereby optimizing the fluid flow path and distribution. The limiting fit of the partition plate 30 ensures its precise position within the liquid chamber 11, preventing random mixing of fluids between chambers and improving heat exchange efficiency. The sealing fit of the partition plate 30 ensures orderly flow of fluid within the first chamber 111 and the second chamber 112, enhancing the heat exchanger's heat exchange performance.

[0046] like Figure 9 , Figure 12 , Figure 13 and Figure 14 As shown, the limiting groove 14 extends along the height direction, and the limiting groove 14 limits the spacer plate 30 along the width and length directions; the surface of the manifold structure and the surface with the mating hole 12 are also provided with a second positioning hole 15 at intervals, the second positioning hole 15 is connected to the liquid cavity 11, the extension direction of the second positioning hole 15 is parallel to the extension direction of the mating hole 12, and the other end of the spacer plate 30 along the height direction is sealed to the second positioning hole 15; wherein, the dimension of the second positioning hole 15 along the length direction is P; the dimension of the limiting groove 14 along the length direction is N, N=P+0.5mm-1mm; the dimension of the limiting groove 14 along the width direction is the depth M of the limiting groove 14 penetrating into the inner wall of the liquid cavity 11, and the dimension of the inner wall of the liquid cavity 11 with the limiting groove 14 along the width direction is the wall thickness F2 of the liquid cavity 11, 0.5mm≤M≤1mm, and M≤0.5*F2.

[0047] By setting a limiting groove 14 extending along the height direction and limiting the spacer plate 30 in the width and length directions, and by setting a second positioning hole 15 on the surface of the manifold structure corresponding to the surface of the mating hole 12, these designs work together to improve the structural stability and assembly accuracy of the heat exchanger, thereby improving the overall performance of the heat exchanger. The fit between the limiting groove 14 and the spacer plate 30: The extension of the limiting groove 14 in the height direction ensures the vertical positioning of the spacer plate 30 within the liquid cavity 11, preventing the spacer plate 30 from shaking or shifting under fluid impact, thus enhancing the stability of the entire manifold structure. Simultaneously, the limiting effect of the limiting groove 14 in the width and length directions further ensures the horizontal positioning of the spacer plate 30, allowing it to maintain precise parallelism within the liquid cavity 11, helping to reduce turbulence losses during heat exchange and improving heat exchange efficiency. The size and fit of the second positioning hole 15: The size P of the second positioning hole 15, and its parallel design with the extension direction of the mating hole 12, ensures that the other end of the spacer plate 30 in the height direction can accurately seal with the second positioning hole 15. This precise sealing fit not only prevents liquid leakage between chambers, but also provides additional support points for the partition plate 30, enhancing its mechanical stability within the liquid chamber 11. It also ensures that the fluid flows along a preset path inside the heat exchanger, avoiding bypass flow and further improving the performance of the heat exchanger.

[0048] In addition, the dimension N of the limiting groove 14 along its length is set to P + 0.5mm - 1mm. This design not only considers the size of the second positioning hole 15, but also reserves a tolerance of 0.5mm-1mm to accommodate dimensional changes during the manufacturing process, ensuring the accurate installation of the partition plate 30. It also allows for a certain amount of thermal expansion space, enhancing the heat exchanger's adaptability to temperature changes. The depth M of the limiting groove 14 matches the wall thickness F2 of the liquid chamber 11: the depth M of the limiting groove 14 in the width direction is limited to between 0.5mm and 1mm, and does not exceed half the wall thickness F2 of the liquid chamber 11, i.e., M ≤ 0.5 * F2. This design ensures the structural strength of the inner wall of the liquid chamber 11 while also ensuring that the limiting groove 14 can provide sufficient lateral limiting for the partition plate 30. By limiting the depth of the limiting groove 14, it avoids both a decrease in the structural strength of the collector body 10 due to excessive depth and poor limiting effect due to excessive shallowness, ultimately achieving structural optimization and functional perfection.

[0049] like Figure 10 , Figure 11 and Figure 12As shown, the heat exchanger also includes multiple liquid flat tubes; the second cavity 112 and the surface with mating holes 12 are respectively provided with multiple flat tube grooves 16, which are connected to the second cavity 112 and are used to communicate with the liquid flat tubes. The multiple liquid flat tubes and the multiple flat tube grooves 16 are respectively provided with one-to-one correspondence; the flat tube grooves 16 extend in the width direction and are spaced apart in the length direction; wherein, the distance between two adjacent flat tube grooves 16 in the length direction is B, 6mm≤B≤10mm; the first cavity 111 and the surface with mating holes 12 are respectively provided with multiple flat tube grooves 16. The surface of the liquid chamber 11 has a flow groove 17, which is connected to the outside of the first cavity 111 and the main body 10. The flow groove 17 extends along the width direction and its dimension along the width direction is D, 40mm≤D≤100mm. The inner wall of the liquid cavity 11 has a wall thickness δ along the width direction, 2mm≤δ≤4mm. The inner diameter of the mating hole 12 is J, and the dimension of the flat tube groove 16 along the length direction is G, J≤BG-2mm. The height dimension of the part of the manifold structure with the mating hole 12 is F1, 2mm≤F1≤5mm.

[0050] By introducing multiple liquid flat tubes and carefully designing the dimensions and layout of the matching flat tube grooves 16, flow channels 17, and related components, the heat exchange efficiency and structural stability of the heat exchanger are effectively improved, while reducing production costs and increasing manufacturing feasibility. The precise fit between the flat tube grooves 16 and the liquid flat tubes: Multiple flat tube grooves 16 are provided on the second cavity 112, communicating with the second cavity 112 for precise fit with the liquid flat tubes. This allows the flat tubes to form complex flow channels inside the heat exchanger, increasing the contact area between the fluid and the heat exchanger wall, thereby improving heat exchange efficiency. The flat tube grooves 16 extend along the width direction and are spaced apart along the length direction. The spacing B between adjacent flat tube grooves 16 is controlled between 6mm and 10mm. This design ensures that the layout of the flat tube grooves 16 is both compact and reasonable, maximizing the use of internal space and facilitating the installation and maintenance of the flat tubes. The flow channel 17 is located on the surface communicating with the first cavity 111 and the outside, with its dimension D controlled between 40mm and 100mm, extending along the width direction. The optimized design of the flow channel 17 not only ensures uniform fluid distribution upon entering the heat exchanger, reducing pressure loss during fluid distribution, but also guarantees smooth liquid flow from the first chamber 111 to the outside, contributing to improved overall fluid dynamics performance. Furthermore, the size range of the flow channel 17 is designed considering the overall layout of the heat exchanger and the adaptability to fluid flow rates, further improving the uniformity and efficiency of fluid distribution. Regarding the selection of the wall thickness of the liquid chamber 11 and the diameter of the mating hole 12: the wall thickness δ of the liquid chamber 11 is set between 2mm and 4mm. This selection ensures sufficient structural strength and pressure resistance of the manifold 10 while also considering lightweight design, reducing the overall weight and manufacturing cost of the heat exchanger. There is a specific relationship between the diameter J of the mating hole 12, the length G of the flat tube groove 16, and the spacing B of the flat tube groove 16, i.e., J ≤ BG - 2mm. This design ensures a tight fit between the baffle column 20 and the manifold body 10, as well as good sealing after the liquid flat tube is installed, reducing the risk of fluid leakage and thus improving the stability and reliability of the heat exchanger. The height F1 of the manifold structure is controlled between 2mm and 5mm. This optimized design fully considers the installation requirements of the baffle column 20 and the compact structure of the manifold body 10, ensuring that the baffle column 20 can smoothly enter the mating hole 12, while also leaving sufficient space for the sealing material, enhancing the sealing effect. Furthermore, the size range of F1 also considers the feasibility of the manufacturing process, ensuring that the manifold structure not only meets performance requirements but also achieves efficient and low-cost manufacturing during production.

[0051] Therefore, through the aforementioned dimensional design and layout optimization, this invention not only improves the heat exchanger's heat exchange efficiency and the uniformity of fluid distribution, but also ensures structural stability and sealing performance, reducing the possibility of fluid leakage. Furthermore, the precise design of component dimensions not only helps reduce production costs and improve manufacturing efficiency, but also facilitates subsequent maintenance and upgrades.

[0052] like Figure 1 and Figure 2 As shown, the main body 10 includes a top plate 40, a bottom plate 50, and a support box 60; the top plate 40 is located at the end of the support box 60 away from the bottom plate 50, and the top plate 40 is fixedly connected to the support box 60 by welding; the support box 60 and the bottom plate 50 are integrally formed, and the support box 60 surrounds the bottom plate 50, and the top plate 40, the bottom plate 50, and the support box 60 together form a liquid cavity 11; multiple mating holes 12 are provided on the top plate 40; a first positioning hole 13 is provided on... On the top plate 40, two limiting grooves 14 are respectively set on the inner walls of the two sides of the support box 60 along the width direction; the support box 60 has a liquid flow hole 18 for connecting with external pipelines, and the liquid flow hole 18 communicates with the liquid cavity 11; the bottom plate 50 has a second positioning hole 15, which communicates with the liquid cavity 11, and the extension direction of the second positioning hole 15 is parallel to the extension direction of the mating hole 12. The other end of the partition plate 30 along the height direction is sealed and fitted with the second positioning hole 15.

[0053] By combining the top plate 40, bottom plate 50, and support housing 60, the connection between the liquid flow hole 18 and the liquid chamber 11, and the placement of the first positioning hole 13 and the second positioning hole 15, the fluid can accurately enter and exit the liquid chamber 11, improving fluid flow efficiency. The welding and fixing of the top plate 40 to the support housing 60, and the sealing fit between the partition plate 30 and the second positioning hole 15, enhance the overall strength and sealing performance of the heat exchanger, extending its service life.

[0054] like Figure 10 , Figure 11 and Figure 12As shown, the bottom plate 50 has a flow groove 17 on the surface of the first cavity 111, which is connected to the outside of the first cavity 111 and the collection body 10. The distance between the side of the bottom plate 50 extending along the width direction and the adjacent flow groove 17 is A, 5mm≤A≤10mm. The flow groove 17 extends along the width direction, and its dimension along the width direction is D, 40mm≤D≤100mm. The heat exchanger also includes multiple liquid flat tubes. The number of liquid flat tubes is N1. The bottom plate 50 has multiple flat tube grooves 16 on the surface of the second cavity 112, which are connected to the second cavity 112 and are used to communicate with the liquid flat tubes. The multiple liquid flat tubes and the multiple flat tube grooves 16 are matched one-to-one. The flat tube grooves 16 extend along the width direction, and the multiple Flat tube grooves 16 are spaced apart along their length; the distance between two adjacent flat tube grooves 16 along their length is B, 6mm≤B≤10mm; the distance between the side extending along the length of the base plate 50 and the adjacent flat tube groove 16 is C, 3mm≤C≤6mm; the dimension of the flat tube groove 16 along its width is the same as the dimension D of the flow channel 17 along its width; the dimension of the flat tube groove 16 along its length is G; the dimension of the inner wall of the liquid chamber 11 along its width is the wall thickness δ of the supporting box 60, 2mm≤δ≤4mm; the dimension of the base plate 50 along its length is E, E≥2*(A+δ)+N1*B+(0.25~0.5)*G*N1+0.5G; the dimension of the base plate 50 along its width is F, F=D+2*(C+δ).

[0055] This embodiment optimizes the fluid inlet and outlet paths by setting flow channels 17 and flat tube grooves 16 on the base plate 50, ensuring uniform fluid distribution within the heat exchanger. Precise dimensional control of the flow channels 17 and flat tube grooves 16, such as parameters A, D, B, C, G, and δ, directly affects the sealing performance after welding and the fluid flow characteristics, thus influencing the heat exchanger's heat exchange efficiency. The rational layout of the flow channels 17 and flat tube grooves 16, and their precise fit with the liquid flat tubes, improves fluid turbulence, enhances heat exchange, reduces fluid resistance, and improves the overall performance of the heat exchanger. In other embodiments, the dimensions of the flow channels 17 and flat tube grooves 16 can be adjusted to adapt to different fluid characteristics and heat exchange requirements. For example, increasing the B value can reduce friction between the fluids in the flat tube grooves 16, but may affect the degree of turbulence within the flat tube grooves 16.

[0056] It should be noted that, in Embodiment 1 of this utility model, compared with the existing integrated design of the manifold structure, the design of Embodiment 1 includes four parts: the first part is the top plate 40, which is fixedly connected to the support box 60 by welding; the second part is the integrated structure of the support box 60 and the bottom plate 50; the third part is the partition plate 30; and the fourth part is multiple turbulence columns 20. The design in Embodiment 1 makes the manufacturing of each part simple and quick, reduces the requirements for the manufacturing process, and solves the problems of long manufacturing time and high cost of the original product. Figure 10 As shown, the setting is 5mm≤A≤10mm. When A is less than 5mm, bending processing can easily cause deformation of the groove openings of the flow groove 17 and the flat tube groove 16, which may lead to the flat tube being unable to be inserted into the flat tube groove 16. When A>10mm, it will waste valuable space and is not conducive to miniaturized and integrated design. The two sides of the main body along the width direction are the inlet and outlet sides and the transition side, respectively. The inlet and outlet sides have liquid flow holes for connecting with external pipelines, and the liquid flow holes are connected to the liquid cavity. The dimension of the inlet and outlet sides along the height direction is not less than the dimension of the transition side along the height direction. However, when it is necessary to increase the flow inside the main body structure, the corresponding partition plate 30 can be added according to the flow distribution. In the structure of the first embodiment, when bending the edge of the flat tube groove 16, the bending reference line and the flat tube groove 16 must be kept at a certain distance. During the manufacturing process, the flat tube groove 16 should be cut first and then bent to avoid deformation of the flat tube groove 16 during subsequent machining, which would cause the flat tube to be unable to be inserted into the flat tube groove 16.

[0057] like Figure 3 As shown, the main body 10 includes a top plate 40, a bottom plate 50, and a support box 60; the bottom plate 50 is located at the end of the support box 60 away from the top plate 40, and the bottom plate 50 is fixedly connected to the support box 60 by welding; the support box 60 is integrally formed with the top plate 40, and the support box 60 surrounds the top plate 40, and the top plate 40, bottom plate 50, and support box 60 together form a liquid cavity 11; multiple mating holes 12 are provided on the top plate 40; a first positioning hole 13 is provided on... On the top plate 40, two limiting grooves 14 are respectively set on the inner walls of the two sides of the support box 60 along the width direction; the support box 60 has a liquid flow hole 18 for connecting with external pipelines, and the liquid flow hole 18 communicates with the liquid cavity 11; the bottom plate 50 has a second positioning hole 15, which communicates with the liquid cavity 11, and the extension direction of the second positioning hole 15 is parallel to the extension direction of the mating hole 12. The other end of the partition plate 30 along the height direction is sealed and fitted with the second positioning hole 15.

[0058] The welded assembly of the base plate 50 and the supporting housing 60 forms a closed liquid chamber 11, ensuring the safe flow of fluid within the heat exchanger. The design of the liquid flow hole 18 provides precise guidance for the fluid's entry and exit, preventing disordered fluid flow and improving heat exchange efficiency. In terms of effectiveness, the welded connection enhances the structural strength and sealing of the collector body 10, thereby improving the reliability of the heat exchanger.

[0059] like Figure 10 , Figure 11 and Figure 12 As shown, the bottom plate 50 has a flow groove 17 on the surface of the first cavity 111, which is connected to the outside of the first cavity 111 and the main body 10. The distance between the side of the bottom plate 50 extending along the width direction and the adjacent flow groove 17 is A, 4mm≤A≤6mm. The flow groove 17 extends along the width direction, and its dimension along the width direction is D, 40mm≤D≤100mm. The heat exchanger also includes multiple liquid flat tubes. The number of liquid flat tubes is N1. The bottom plate 50 has multiple flat tube grooves 16 on the surface of the second cavity 112, which are connected to the second cavity 112 and are used to communicate with the liquid flat tubes. The multiple liquid flat tubes and the multiple flat tube grooves 16 are matched one-to-one. The flat tube grooves 16 extend along the width direction, and Multiple flat tube grooves 16 are spaced apart along the length direction; the distance between two adjacent flat tube grooves 16 along the length direction is B, 6mm≤B≤10mm; the distance between the side extending along the length direction of the base plate 50 and the adjacent flat tube groove 16 is C, C=δ+(3~4mm); the dimension of the flat tube groove 16 along the width direction is the same as the dimension D of the flow channel 17 along the width direction; the dimension of the flat tube groove 16 along the length direction is G; the dimension of the inner wall of the liquid cavity 11 along the width direction is the wall thickness δ of the supporting box 60, 2mm≤δ≤4mm; the dimension of the base plate 50 along the length direction is E, E≥2*A+N1*B+(0.25~0.5)*G*N1+0.5G; the dimension of the base plate 50 along the width direction is F, F=D+2*C.

[0060] By precisely designing the flow channel 17 and flat tube groove 16 on the base plate 50, the flow path of the fluid within the heat exchanger is optimized, ensuring uniform fluid distribution and efficient heat exchange. The dimensional parameters A, D, B, C, G, and δ of the flow channel 17 and flat tube groove 16 directly affect the sealing performance after welding and the fluid flow characteristics, thus influencing heat exchange efficiency. The rational layout of the flow channel 17 and flat tube groove 16, and their precise fit with the liquid flat tube, improves the turbulence of the fluid, enhances the heat exchange effect, reduces fluid resistance, and improves the overall performance of the heat exchanger. In other embodiments, by adjusting the dimensions of the flow channel 17 and flat tube groove 16, different fluid characteristics and heat exchange requirements can be accommodated. For example, reducing the B value can increase turbulence between the flat tube grooves 16, but may affect the fluid flow resistance.

[0061] It should be noted that in Embodiment 2 of this utility model, since the structure of Embodiment 1 may experience some deformation during the manufacturing process, Embodiment 2 is further optimized based on Embodiment 1. The design of Embodiment 2 includes four parts: the first part is the base plate 50, which is fixedly connected to the support box 60 by welding; the second part is the structure in which the support box 60 and the top plate 40 are integrally formed; the third part is the partition plate 30; and the fourth part is multiple baffle columns 20. The base plate 50 and the support box 60 are separated, making the manufacturing of each part simple and quick, reducing the requirements for the manufacturing process, and solving the problems of long manufacturing time and high cost of the original product. In Embodiment 2, because the base plate 50 and the support box 60 are separated, the problem of deformation of the flat tube groove 16 caused by the bending of the box in Scheme 1 is eliminated, so that the accuracy of the flat tube groove 16 can fully meet the requirements of the drawings and manufacturing, and it is easier to assemble the flat tube. Other designs not shown are basically the same as those in Embodiment 1.

[0062] like Figure 4 As shown, the main body 10 includes a top plate 40, a bottom plate 50, and a support box 60. The bottom plate 50 is located at the end of the support box 60 away from the top plate 40. The support box 60, top plate 40, and bottom plate 50 are separately arranged and fixedly connected by welding. The top plate 40, bottom plate 50, and support box 60 together form a liquid cavity 11. Multiple mating holes 12 are provided on the top plate 40. A first positioning hole 13 is provided on the top plate 40. Two limiting grooves 14 are correspondingly provided on the inner walls of the support box 60 on both sides along the width direction. The support box 60 has a liquid flow hole 18 for connecting with an external pipeline, and the liquid flow hole 18 communicates with the liquid cavity 11. The bottom plate 50 has a second positioning hole 15, which communicates with the liquid cavity 11. The extension direction of the second positioning hole 15 is parallel to the extension direction of the mating hole 12. The other end of the partition plate 30 along the height direction is sealed to the second positioning hole 15.

[0063] It should be noted that in Embodiment 3 of this utility model, based on the potential problems in Embodiment 2, Embodiment 3 further optimizes the square manifold structure. In Embodiment 3, the supporting box 60, top plate 40, and bottom plate 50 are evenly separated, making the design include five parts: the first part is the bottom plate 50, the second part is the supporting box 60, the third part is the top plate 40, the fourth part is the partition plate 30, and the fifth part is multiple turbulence columns 20. This further reduces the forming process of the parts and eliminates the adverse effects such as deformation caused by machining. Embodiment 3 further eliminates the problem of deformation of the flat tube groove 16 caused by the bending of the box in Scheme 1, so that the accuracy of the flat tube groove 16 can fully meet the requirements of the drawings and manufacturing, and it is easier to assemble the flat tube. Other designs not shown are basically the same as in Embodiment 1.

[0064] like Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, the top plate 40 has a height dimension of F1, where 2mm ≤ F1 ≤ 5mm; the bottom plate 50 has a flow groove 17 on the surface of the first cavity 111, which is connected to the outside of the first cavity 111 and the main body 10; the distance between the side of the bottom plate 50 extending in the width direction and the adjacent flow groove 17 is A, where 4mm ≤ A ≤ 6mm; the flow groove 17 extends in the width direction, and its dimension in the width direction is D, where 40mm ≤ D ≤ 100mm; the heat exchanger also includes multiple liquid flat tubes; the number of liquid flat tubes is N1; the bottom plate 50 has multiple flat tube grooves 16 on the surface of the second cavity 112, which are connected to the second cavity 112 and used to communicate with the liquid flat tubes; the multiple liquid flat tubes and the multiple flat tube grooves 16 are matched one-to-one; the flat tube grooves 16 extend in the width direction, and the multiple flat tube grooves 16 extend in the length direction. The flat tube grooves 16 are spaced apart; the distance between two adjacent flat tube grooves 16 along the length direction is B, 6mm≤B≤10mm; the distance between the side of the bottom plate 50 extending along the length direction and the adjacent flat tube groove 16 is C, C=δ+(3~4mm); the dimension of the flat tube groove 16 along the width direction is the same as the dimension D of the flow groove 17 along the width direction; the dimension of the flat tube groove 16 along the length direction is G; the dimension of the inner wall of the liquid chamber 11 along the width direction is the wall thickness δ of the support box 60, 2mm≤δ≤4mm; the dimension of the bottom plate 50 along the length direction is E, E≥2*A+N1*B+(0.25~0.5)*G*N1+0.5G; the dimension of the bottom plate 50 along the width direction is F, F=D+2*C; the dimension of the support box 60 along the length direction is K, K=E-2mm; the dimension of the support box 60 along the width direction is L, L=F-2mm.

[0065] Through the above-mentioned series of fine adjustments to the dimensions and layout of key components such as the top plate 40, bottom plate 50, flat tube groove 16, and flow groove 17, more efficient heat exchange performance, more stable structure, and more convenient manufacturing and maintenance capabilities are achieved. The height dimension F1 of the top plate 40 is strictly controlled between 2mm and 5mm. This design ensures a tight fit between the turbulence column 20 and the top plate 40, effectively reducing energy loss when the fluid passes through the manifold structure, while ensuring the compactness and stability of the top structure, which is conducive to improving the degree of fluid disturbance and heat exchange efficiency. The dimensions of the flow groove 17 and flat tube groove 16 of the bottom plate 50 are optimized: the flow groove 17 on the bottom plate 50 is connected to the outside of the manifold body 10, and its dimension D along the width direction is set between 40mm and 100mm, ensuring sufficient fluid distribution space, reducing fluid resistance, and enhancing the uniformity of fluid distribution. Meanwhile, the dimensions D of the flat tube groove 16 and the flow groove 17 are matched. Multiple flat tube grooves 16 are spaced apart along the length direction, and the distance B between adjacent grooves is controlled between 6mm and 10mm. This arrangement not only maximizes the installation density of flat tubes on the base plate 50, but also maintains sufficient gaps between the liquid flat tubes, avoids interference with fluid flow, and improves the heat exchange area utilization and heat exchange efficiency. The layout of the base plate 50 with the flat tube groove 16 and the flow groove 17: the distance A between the side of the base plate 50 along the width direction and the flow groove 17 is set between 4mm and 6mm. This distance ensures the structural strength of the flow groove 17, while providing sufficient guiding and buffering space for the fluid to enter and leave the first chamber 111. The distance C between the flat tube groove 16 and the side of the base plate 50 is equal to δ plus 3 to 4 mm, where δ represents the wall thickness of the liquid cavity 11, controlled between 2 mm and 4 mm. This design effectively balances the depth of the flat tube groove 16 and the thickness of the base plate 50, ensuring good sealing effect and structural rigidity. The dimensions E along the length direction and F along the width direction of the base plate 50 are precisely calculated based on the flat tube groove 16, the flow channel 17, and other dimensional parameters. E≥2*A+N1*B+(0.25~0.5)*G*N1+0.5G, ensuring the orderly arrangement of the liquid flat tubes and the effective allocation space of the flow channel 17. F=D+2C ensures the appropriate distance between the flat tube groove 16 and the flow channel 17, as well as the rationality of the width direction of the base plate 50. The dimensions K along the length direction and L along the width direction of the support box 60 are 2 mm smaller than the corresponding dimensions of the base plate 50. This slight difference helps to improve the sealing of the overall structure and the tightness during assembly, reduces the risk of leakage, and improves the convenience of manufacturing and assembly.

[0066] Furthermore, by setting reasonable ranges for various dimensional parameters, such as B, C, D, E, F, G, and δ, this invention effectively simplifies the manufacturing process and avoids the manufacturing difficulties caused by overly precise and complex dimensional requirements. This not only helps reduce production costs but also makes mass production possible, improving production efficiency. The independent design of the flat tube groove 16 and the flow groove 17, as well as the precise layout between the components, allows for easy disassembly and assembly of the liquid flat tubes and cleaning of the channels during heat exchanger maintenance and cleaning, reducing maintenance time and costs. Simultaneously, the optimization of dimensional parameters also helps reduce potential structural failures and extends the service life of the heat exchanger.

[0067] like Figure 5 , Figure 6 and Figure 7 As shown, the main body 10 includes a top plate 40, a bottom plate 50, and a support box 60; the support box 60 includes a connecting body 61, a left end plate 62, and a right end plate 63; the bottom plate 50 is located at the end of the connecting body 61 away from the top plate 40, and the connecting body 61, the top plate 40, and the bottom plate 50 are integrally formed. The left end plate 62 and the right end plate 63 are respectively fixed to the two ends of the connecting body 61 along the length direction by welding; the top plate 40, the bottom plate 50, and the support box 60 together form a liquid cavity 11; multiple mating holes 12 are provided on the top plate 40. On the plate 40; the first positioning hole 13 is provided on the top plate 40; two limiting grooves 14 are respectively provided on the inner walls of the two sides of the connecting body 61 along the width direction; the connecting body 61 has a liquid flow hole 18 for connecting with an external pipeline, the liquid flow hole 18 is connected to the liquid cavity 11; the bottom plate 50 has a second positioning hole 15, the second positioning hole 15 is connected to the liquid cavity 11, the extension direction of the second positioning hole 15 is parallel to the extension direction of the mating hole 12, and the other end of the partition plate 30 along the height direction is sealed to the second positioning hole 15.

[0068] By designing the support housing 60 as a combination of a connecting body 61, a left end plate 62, and a right end plate 63, where the connecting body 61 is integrally formed with the top plate 40 and the bottom plate 50, and the left end plate 62 and the right end plate 63 are fixed by welding, the manufacturing process of the flow collector 10 is simplified, and the compactness and strength of the structure are improved. The design of the liquid flow hole 18, and the setting of the first positioning hole 13 and the second positioning hole 15, provide precise guidance for the fluid to enter and exit, avoid disordered fluid flow, and improve heat exchange efficiency. Through integral forming and welding connection, this embodiment improves the structural strength and sealing performance of the flow collector 10, thereby enhancing the reliability of the heat exchanger. In other embodiments, the left end plate 62 and the right end plate 63 can be connected to the connecting body 61 by other fixing methods such as bonding and riveting. Although sealing can also be achieved, welding is a better way to ensure the stability and safety of the structure under high temperature and high pressure environments.

[0069] like Figure 10 , Figure 11 and Figure 12 As shown, the partition plate 30 enters the liquid chamber 11 through the first positioning hole 13; the top plate 40 has a height dimension of F1, 2mm≤F1≤5mm; the bottom plate 50 has a flow groove 17 on the surface of the first chamber 111, which is connected to the outside of the first chamber 111 and the main body 10; the distance between the side of the bottom plate 50 extending in the width direction and the adjacent flow groove 17 is A, 4mm≤A≤6mm; the flow groove 17 extends in the width direction, and its dimension in the width direction is D, 40mm≤D≤100mm; the heat exchanger also includes multiple liquid flat tubes; the number of liquid flat tubes is N1; the bottom plate 50 has multiple flat tube grooves 16 on the surface of the second chamber 112, which are connected to the second chamber 112 and are used to communicate with the liquid flat tubes. The grooves 16 are matched one-to-one; the flat tube grooves 16 extend along the width direction, and multiple flat tube grooves 16 are spaced apart along the length direction; the distance between two adjacent flat tube grooves 16 along the length direction is B, 6mm≤B≤10mm; the distance between the side of the bottom plate 50 extending along the length direction and the adjacent flat tube groove 16 is C, 3mm≤C≤4mm; the dimension of the flat tube groove 16 along the width direction is the same as the dimension D of the flow groove 17 along the width direction; the dimension of the flat tube groove 16 along the length direction is G; the dimension of the inner wall of the liquid cavity 11 along the width direction is the wall thickness δ of the connecting body 61, 2mm≤δ≤4mm; the dimension of the bottom plate 50 along the length direction is E, E≥2*A+N1*B+(0.25~0.5)*G*N1+0.5G; the dimension of the bottom plate 50 along the width direction is F, F=D+2*(C+δ).

[0070] By precisely controlling the dimensional parameters of the top plate 40 and the bottom plate 50, and by rationally arranging the flat tube groove 16 and the flow channel 17, the flow path of the fluid within the heat exchanger is optimized, ensuring uniform fluid distribution and efficient heat exchange. The partition plate 30 enters the liquid chamber 11 through the first positioning hole 13, effectively separating the liquid chamber 11. Furthermore, through precise cooperation with the flat tube groove 16 and the flow channel 17, it guides the fluid to flow orderly within the chamber, improving heat exchange efficiency. In terms of effect, the rational layout and precise dimensional control enhance the turbulence of the fluid, strengthen the heat exchange effect, reduce fluid resistance, and improve the overall performance of the heat exchanger.

[0071] It should be noted that in Embodiment 4 of this utility model, in order to solve the problem of the large number of coordination requirements between the five parts in Embodiment 3, which leads to high requirements for the assembly accuracy of the parts, Embodiment 4 further optimizes the square manifold structure. The manifold body 10 includes a top plate 40, a bottom plate 50 and a support box 60; the support box 60 includes a connecting body 61, a left end plate 62 and a right end plate 63. The connecting body 61, the top plate 40 and the bottom plate 50 are integrally formed by stamping. The square manifold structure in Embodiment 4 is set into five parts that are easier to process. The first part is an integral structure formed by connecting the body 61, the top plate 40 and the bottom plate 50, the second part is the left end plate 62, the third part is the right end plate 63, the fourth part is the partition plate 30, and the fifth part is multiple turbulence columns 20. This setting facilitates subsequent welding and sealing, improves welding quality, reduces leakage rate and improves manufacturing efficiency.

[0072] Specifically, the manifold structure has mutually perpendicular length, width, and height directions; the manifold body 10 has an inlet / outlet side and a transition side on both sides along the width direction, and the inlet / outlet side has a liquid flow hole 18 for connecting to an external pipeline, the liquid flow hole 18 communicating with the liquid chamber 11; wherein, the dimension of the inlet / outlet side along the height direction is not less than the dimension of the transition side along the height direction; and / or, as Figure 8 As shown, the turbulence column 20 includes an extension section 21 and a fixed section 22 connected sequentially along the axial direction. The fixed section 22 is fixed to the flow collection body 10 by welding and the fixed section 22 seals the mating hole 12. The extension section 21 is located in the liquid cavity 11 to perform flow diversion.

[0073] By designing the flow collector 10 with inlet and outlet sides and transition sides of different heights, the fluid inlet and outlet paths are optimized, ensuring uniform fluid distribution within the heat exchanger. The design of the liquid flow hole 18, and the placement of the extension section 21 and fixed section 22 of the turbulence column 20, alters the fluid flow path, increases the contact area between the fluid and the heat exchanger, and thus improves heat exchange efficiency. Through the distribution of the extension section 21 within the liquid cavity 11, this embodiment enhances the turbulence of the fluid, strengthens the heat exchange effect, reduces fluid resistance, and improves the overall performance of the heat exchanger. In other embodiments, the turbulence column 20 can also be achieved through threaded connections or other mechanical fixing methods. While these methods also achieve a turbulence effect, welding is more reliable in terms of long-term operational stability and pressure resistance.

[0074] In summary, this utility model provides a heat exchanger. By setting the main body 10 and multiple baffle columns 20 as separate structures and subsequently sealing and fixing them by welding or other methods, the main body 10 and the baffle columns 20 can be processed and formed separately. This simplifies the internal structure of the main body 10, reduces the overall manufacturing difficulty of the manifold, and eliminates the need for particularly precise machining techniques when forming the main body 10 and the baffle columns 20. This reduces the precision requirements of manufacturing equipment and processes, simplifies the processing operations of workers, effectively reduces processing costs and time, improves batch processing efficiency and product quality stability, and can meet the actual needs of large-scale and high-efficiency manifold production. In addition, the separate design of the main body 10 and the baffle columns 20 also facilitates the subsequent maintenance and upgrade design of the manifold product. This utility model has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of high manufacturing difficulty, high processing cost and long processing time of the manifold in existing heat exchangers, making them unsuitable for efficient mass production. It is suitable for large-scale promotion and use.

[0075] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
