Description

Technical Field

[0001] This invention relates to an interconnect for heat exchangers applicable to the automotive field, particularly for heat exchangers used in electronic control units. Background Technology

[0002] Electronic control units (ECUs) are known to require thermal management. Integrated circuits or other electronic or electrical components generate heat during operation. In the case of integrated circuits, power is dissipated over small surfaces. The heat generated in this way needs to be effectively dissipated, especially when the components are operating under high loads. High-performance units require dedicated cooling equipment to enable them to operate efficiently. One known way to solve this problem is to use air to directly cool the heat source.

[0076] To simplify the description of this invention, a Cartesian reference (o, x, y, z) is formed, and the direction ox is defined as the length direction, oy as the height direction, and oz as the width direction, as follows. Figure 1 and Figure 2 As shown.

[0077] Figure 1 A perspective view shows a heat exchanger assembly 100 having a heat exchanger 200 and multiple heat source modules 410, 420, 430, 440. The heat exchanger 200 includes a first pipe 210 for a heat exchange fluid. The heat exchange fluid flows through the heat exchanger 200, particularly through the first pipe 210, enabling heat exchange between the heat exchanger 200 and any heat source in contact with it. The heat exchange fluid can be a refrigerant (e.g., R134A, R-1234YF, or R744) or a coolant (e.g., an ethylene glycol-water mixture).

[0078] The heat exchanger 200 may also include a second pipe 220 for heat exchange fluid, the second pipe 220 being fluidly connected to the first pipe 210. The first pipe 210 and the second pipe 220 may be connected by one or more interconnectors 260, allowing fluid to flow between them.

[0079] The heat exchanger assembly 100 includes at least a first heat source module 410. Figure 1In the illustrated embodiment, the heat exchanger assembly 100 includes a first heat source module 410, a second heat source module 420, a third heat source module 430, and a fourth heat source module 440.

[0080] The first heat source module 410 is adjacent to the first pipe 210, so that the heat from the first heat source module 410 can be dissipated into the first pipe 210.

[0081] In the illustrated embodiment, the first heat source module 410 and the second heat source module 420 are adjacent to the first tube 210. The second tube 220 is adjacent to the third heat source module 430 and the fourth heat source module 440. In other words, the first tube 210 is sandwiched between the first heat source module 410 and the second heat source module 420, while the second tube 220 is sandwiched between the third heat source module 430 and the fourth heat source module 440. The term "sandwiched in the middle" means that the first tube 210 and the second tube 220 are in contact with the respective heat source modules and are located between the respective heat source modules, taking into account the presence of any thermal paste that can be used between their surfaces to improve heat exchange.

[0082] Figure 2 An example of the extension planes of selected components of the heat exchanger assembly 100 is schematically shown. A first pipe 210 extends within a first pipe extension plane A. A second pipe 220 extends within a second pipe extension plane B. A first heat source module 410 extends within a first heat source module extension plane C. A second heat source module 420 extends within a second heat source module extension plane D. A third heat source module 430 extends within a third heat source module extension plane E. A fourth heat source module 440 extends within a fourth heat source module extension plane F. "Extension within an extension plane" here refers to two dimensions of a three-dimensional component being significantly larger than the third dimension, wherein two dimensions are measured within the extension plane. The third dimension is measured perpendicular to the extension plane. In other words, a component extending within an extension plane is a generally flat component whose height is relatively small compared to its width and length. Preferably, all extension planes A, B, C, D, E, and F extend parallel to each other.

[0083] In the illustrated embodiment, the first tube 210 and the second tube 220 extend primarily along axis X and to a lesser extent along axis Z, meaning their length is greater than their width. Their height is substantially smaller than the other two dimensions.

[0084] The first heat source module 410 and the third heat source module 430 similarly extend primarily along axis X and to a lesser extent along axis Z, meaning their length is greater than their width. Their height is substantially smaller than the other two dimensions.

[0085] The second heat source module 420 and the fourth heat source module 440 extend primarily along axis Y and to a lesser extent along axis Z, meaning that their width is greater than their length (an opposite arrangement could also be conceived). Their height is substantially smaller than the other two dimensions.

[0086] It should be noted that there may be multiple second heat source modules 420 arranged along the first pipe 210, and multiple fourth heat source modules 440 arranged along the second pipe 220. Similarly, depending on the configuration of the unit, multiple first heat source modules 410 and third heat source modules 430 may be arranged along the first pipe 210 and the second pipe 220.

[0087] Figure 3 Shown in exploded view Figure 1 The heat exchanger assembly 100 includes a first heat source module 410 comprising at least one first heat source 411. In the illustrated embodiment, the first heat source module 410 includes a plurality of first heat sources 411. Preferably, the plurality of first heat sources 411 extend parallel to the main extension axis of the first tube 210, such that the single first tube 210 can meet the heat exchange requirements of the entire first heat source module 410. In one embodiment, the first heat source module 410 is a PCB board. The first heat source 411 may be a separate integrated circuit.

[0088] The second heat source module 420 includes at least one second heat source 421.

[0089] In the illustrated embodiment, the second heat source module 420 is in the form of a box 422, as shown in the figure below. Figure 8 As shown in detail. In one embodiment, the second heat source module 420 is in the form of a box 422, in which a PCB board having at least one integrated circuit is located.

[0090] The third heat source module 430 includes at least one third heat source 431. In the illustrated embodiment, the third heat source module 430 includes multiple third heat sources 431. Preferably, the multiple third heat sources 431 extend parallel to the main extension axis of the second tube 220, such that the single second tube 220 can meet the heat exchange requirements of the entire third heat source module 430. In one embodiment, the third heat source module 430 is a PCB board. The third heat source 431 may be an integrated circuit.

[0091] The fourth heat source module 440 includes at least one fourth heat source 441. In one embodiment, the fourth heat source module 440 is in the form of a box 422, in which a PCB board having at least one integrated circuit is located.

[0092] Figure 4 and Figure 5The heat exchanger assembly 100 and the chassis 500 having the heat exchanger 200 are shown in perspective views. The heat exchanger assembly 100 may include the chassis 500, which serves as a mounting point for all components and enables the heat exchanger assembly 100 to be integrated into other structures, such as dedicated racks or vehicle structures.

[0093] The chassis 500 preferably includes a housing 501 that defines an internal volume 502. A first heat source module 410 may be located within the internal volume 502. Preferably, a third heat source module 430 is also located within the internal volume 502. The chassis 500 with housing 501 allows for the first heat source module 410 and the third heat source module 430 to have PCB-like structures without additional protection, as housing 501 can be configured to form a separate enclosure protecting internal components from external harmful factors such as moisture, debris, or moving parts of the vehicle. Housing 501 may include housing openings 511 that expose connectors (not shown) of the first and third heat source modules 410 and 430 for connection to external signal and / or power lines, and allow the second and fourth heat source modules 420 and 440 to connect to components located within housing 501.

[0094] In the illustrated embodiment, the first tube 210 is located externally relative to the housing 501. The second tube 220 may also be located externally relative to the housing 501. Therefore, any heat source module external to the housing 501 can also be cooled by the heat exchanger 200 of the heat exchanger assembly 100. Specifically, the second heat source module 420 may be externally attached to the chassis 500 relative to the housing 501. Similarly, the fourth heat source module 440 may be externally attached to the chassis 500 relative to the housing 501.

[0095] Figure 6 and Figure 7 The chassis 500 without the heat exchanger 200 is shown in perspective views viewed from above and below. The housing 501 of the chassis 500 may include a main groove 503 for the first tube 210. The main groove 503 may at least partially surround the first tube 210. In other words, the main groove 503 forms a recess within the housing 501 in which the first tube 210 can be placed. Therefore, the top of the first tube 210 may be flush with the housing 501. The main groove 503 allows for a compact assembly, particularly when the second heat source 420 is also attached to the housing 501 of the chassis 500, as shown above.

[0096] The housing 501 may have a main partition wall 504 between the first tube 210 and the first heat source module 410. As explained in detail with reference to the additional drawings, the heat exchanger 200 may include an attachment 300 attached to the first tube 210 and / or the second tube 220 and projecting substantially vertically from the first tube 210 and / or the second tube 220. In this case, the main partition wall 504 may include at least one main attachment opening 505 through which the attachment 300 protrudes. In the illustrated embodiment, two attachments 300 are placed on the first tube 210. Therefore, two main attachment openings 505 are also present. The two main attachment openings 505 may have different sizes to accommodate attachments 300 of different sizes.

[0097] In one embodiment, housing 501 has an interconnect cutout 510 that at least partially encloses one or more interconnects 260 extending between the first tube 210 and the second tube 220. In other words, the interconnect cutout 510 forms a recess within housing 501 in which the one or more interconnects 260 can be placed. This allows for improved component compactness.

[0098] like Figure 7 As shown, housing 501 may have a secondary groove 506 for the second tube 220, the secondary groove 506 may at least partially surround the second tube 220, similar to the main groove 503 relative to the first tube 210.

[0099] The housing 501 may have a secondary partition wall 507 between the second tube 220 and the third heat source module 430. The second partition wall 507 may include one or more second attachment openings 508 through which any attachment 300 of the second tube 220 protrudes. The secondary attachment openings 508 may have different sizes to accommodate attachments 300 of different sizes.

[0100] The housing 501 may include housing attachment points 512 for direct attachment of the first tube 210 and the second tube 220 when needed. For example, the housing attachment point 512 may be in the form of a base having an opening for a screw, while the first tube 210 and the second tube 220 may have corresponding tube attachment tabs 202 (e.g., Figure 18 , 19 As shown), the tube attachment tab 202 also has an opening, allowing the components to be fastened together with screws.

[0101] Figure 8A perspective view taken from the bottom shows a heat source module in the form of a box 422, in this case, a second heat source module 420. The second heat source module 420 includes a second heat source 421, such as a PCB board having one or more integrated circuits. In the illustrated embodiment, the second heat source module 420 encapsulates the second heat source 421. The box 422 may be a housing defining an enclosed volume within which the second heat source 421 is located. A box opening 423 may be provided to allow the second heat source module 420 to be connected to other components of the chassis 500 or external signal or power lines.

[0102] Figure 9 The heat exchanger 200 and the heat source module, here designated as the first heat source module 410, are shown in an exploded view from below. The first heat source module 410, having a plurality of first heat sources 411, is positioned between the first tube 210 and the second tube 220, and is in contact with the first tube 210. The first tube 210 may be made of a heat exchange plate 201. In the illustrated embodiment, the first tube 210 includes a first flat plate 211 (as shown in...). Figure 10 (See more clearly in the image) and the first forming plate 212, the first flat plate 211 and the first forming plate 212 are connected to each other to form a first pipe channel 2103 for heat exchange fluid. Generally, a flat plate refers to a plate that is usually flat and facilitates the formation of any fluid channel through its flat portion. Since the first pipe 210 includes an attachment 300 having a contact portion 305 for ensuring direct contact with the first heat source 411, effective heat exchange can be provided. The second heat source module 420 may be adjacent to the first flat plate 211 so that heat dissipated therefrom can be received by the first pipe 210.

[0103] Figure 10 and Figure 11 The heat exchanger 200 is shown in perspective views viewed from above and below. The second tube 220 may be made of heat exchange plate 201. In the illustrated embodiment, the second tube 220 includes a second flat plate 221 and a second shaped plate 222, which are connected to each other to form a second tube channel 2203.

[0104] The first plate 211 and the second plate 221, as well as the first forming plate 212 and the second forming plate 222, include fluid openings 250 (as shown in...). Figure 18 , 19 (as can be seen better in the image), allowing fluid to flow into and out of the first pipe 220 and the second pipe 220. In this case, the interconnector 260 can connect to the corresponding opening 250.

[0105] Preferably, the second pipe 220 includes one or more attachments 300 having multiple contact portions 305 exposed to multiple third heat sources 431. The attachments may be mounted on the second pipe 220 adjacent to the second pipe channel 2203.

[0106] In the illustrated embodiment, the first forming plate 212 and the second forming plate 222 face each other.

[0107] Figure 12 Another example of the heat exchanger 200 is shown in a perspective view from above, in which the first forming plate 212 faces away from the second forming plate 222. Any of the first plate 211, the first forming plate 212, the second plate 221, and the second forming plate 222 may have one or more attachments 300 fixed thereto, depending on the heat exchange requirements and the placement of a particular heat source. In this case, the first plate 211 and the second forming plate 222 are equipped with attachments 300 to facilitate heat exchange with various heat sources located between the first tube 210 and the second tube 220.

[0108] Figure 13 Another example of the heat exchanger 200 is shown in a perspective view from above, in which the first plate 211 and the second plate 221 face each other. Any of the first plate 211, the first forming plate 212, the second plate 221, and the second forming plate 222 may have one or more attachments 300 fixed thereto, depending on the heat exchange requirements and the placement of a particular heat source.

[0109] Figure 14 and Figure 15 Another example of a heat exchanger 200 is shown in perspective views from above and below. The heat exchanger 200 may include a third tube 230 arranged in series with the first tube 210 and the second tube 220. In other words, the third tube 230 may be attached to the second tube 220 on its opposite side compared to the first tube 210. The third tube 230 may be connected to the second tube 220 via an additional interconnect 360. (As shown in...) Figure 31 and Figure 32 As explained in the context, the first tube 210 includes a first tube inlet 2101 and a first tube outlet 2102 interconnected by a first tube channel 2103, while the second tube 220 may include a second tube inlet 2201 and a second tube outlet 2202 interconnected by a second tube channel 2203.

[0110] The second pipe 220 may include an additional second pipe inlet 2204 and an additional second pipe outlet 2205, for example, positioned on opposite sides of the second pipe 220 relative to the second pipe inlet 2201 and the second pipe outlet 2202. The additional second pipe inlet 2204 and the additional second pipe outlet 2205 may be interconnected via a second pipe channel 2203. The third pipe 230 includes a third pipe inlet 2301 and a third pipe outlet 2302 interconnected via a third pipe channel 2303.

[0111] The third tube 230 may include a third flat plate 231 and a third forming plate 232 connected to each other to form a third fluid channel 2303, wherein the third flat plate 231 and the third forming plate 232 include a third tube inlet 2301 and a third tube outlet 2302 to allow fluid to flow into and out of the third tube 230. The attachment 300 may be used for the third tube 230 in the same manner as the first tube 210 and the second tube 220. In any case, the third tube 230 may have a structure similar to that of the first tube 210 and / or the second tube 220. Multiple third tubes 230 may exist in addition to the first tube 210 and the second tube 220.

[0112] In the example shown, the third forming plate 232 faces the second flat plate 221.

[0113] Figure 16 Another example of a heat exchanger 200 is shown in a perspective view taken from below. Figure 14 and Figure 15 Compared to the example of heat exchanger 200, here the third forming plate 232 faces the second forming plate 222.

[0114] The heat exchanger may include an additional interconnect 360 having a body 261 having an upper inlet 2611 and a lower inlet 2621 connected by an inlet conduit 2801, and an upper outlet 2614 and a lower outlet 2624 connected by an outlet conduit 2802.

[0115] The inlet conduit 2801 and the outlet conduit 2802 can be fluidly isolated from each other within the additional interconnect 360.

[0116] An additional interconnector 360 may be located between the second tube 220 and the third tube 230.

[0117] The additional interconnect 360 can be connected to the additional second pipe inlet 2204 through the upper inlet 2611 of the additional interconnect 360, and to the additional second pipe outlet 2205 through the upper outlet 2614 of the additional interconnect 360.

[0118] The additional interconnect 360 can be connected to the third pipe inlet 2301 through the lower inlet 2621 of the additional interconnect 360, and connected to the third pipe outlet 2302 through the lower outlet 2624 of the additional interconnect 360.

[0119] Figure 17 Another example of the heat exchanger 200 is shown in a perspective view from above. The body 261 of the additional interconnector 360 may include an external inlet 2651 communicating with the inlet conduit 2801 of the additional interconnector 360 and an external outlet 2653 communicating with the outlet conduit 2802 of the additional interconnector 360.

A first pipe 210 and a second pipe 220 can be connected via an interconnect 260 to mechanically attach one to the other and allow heat exchange fluid to travel between them. Specifically, the first pipe inlet 2101, the first pipe outlet 2102, the second pipe inlet 2201, and the second pipe outlet 2202 of the first pipe 210 and the second pipe 220 (as shown in the image) Figure 19 and 20 (As shown) are connected via interconnect 260 to allow fluid to flow between them.

[0121] Figure 19 An example of a first tube 210 is shown. The first tube 210 includes a first tube passage 2103 for guiding heat exchange fluid through the first tube 210. The first tube 210 includes a first tube inlet 2101 and a first tube outlet 2102 for introducing and discharging heat exchange fluid from the first tube 210, respectively.

[0122] In the illustrated embodiment, the first conduit 2103 forms a U-shaped flow path having a first arm 214 and a second arm 215. Fluid openings 250 may be arranged at opposite ends of the U-shaped flow path.

[0123] about Figure 20 The first pipe 210 and the second pipe channel 2203 can form a U-shaped flow path having a first arm 214 and a second arm 215. Fluid openings 250 can be arranged at opposite ends of the U-shaped flow path. The U-shaped flow path of the first pipe 210 can have a different length than the U-shaped flow path of the second pipe 220. Typically, the first pipe 210 can be shorter than the second pipe 220. Alternatively, the first pipe 210 can be longer than the second pipe 220. The first pipe 210 can also have the same length as the second pipe 220.

[0124] The first arm 214 can be divided into at least two parallel sub-channels 216. The second arm 215 can be formed by a single conduit 217. This diversion can be used to aid flow in the balancing plate. It can also concentrate flow to specific hot spots for a better heat transfer coefficient.

[0125] The first arm 214 can be separated from the second arm 215 by a first wall 253 extending away from the end of the U-shaped flow path. At least two sub-channels 216 can be separated from each other by a second wall 254 extending away from the end of the U-shaped flow path. The first wall 253 can extend further away from the end of the U-shaped flow path than the second wall 254. As mentioned above, this also helps to manage heat exchange. Preferably, at least two parallel sub-channels 216 terminate at a common fluid opening 250.

[0126] In the illustrated embodiment, the first forming plate 212 may include a stamped recess 218, which together with the surface of the first plate 211 forms a first tube channel 2103. The stamped recess 218 may have a flat surface at the bottom and be positioned away from the first plate 211.

[0127] Figure 20 An example of a second pipe 220 is shown. The second pipe 220 includes a second pipe passage 2203 for guiding heat exchange fluid through the second pipe 220. The second pipe 220 includes a fluid opening 250 for introducing and discharging heat exchange fluid from the second pipe 220.

[0128] Preferably, one end of the second pipe channel 2203 has two fluid openings 250 for allowing fluid to flow into the second pipe 220, and the other end of the second pipe channel 2203 has two fluid openings 250 for allowing fluid to flow out of the second pipe 220. In this case, each pair of fluid openings 250 includes one fluid opening 250 in the second plate 221 and one fluid opening 250 in the second forming plate 222.

[0129] In the illustrated embodiment, the second conduit 2203 forms a U-shaped flow path having a first arm 214 and a second arm 215. Fluid openings 250 may be arranged at opposite ends of the U-shaped flow path.

[0130] The second pipe channel 2203 can form a U-shaped flow path with a first arm 214 and a second arm 215. Fluid openings 250 can be arranged at opposite ends of the U-shaped flow path.

[0131] The first arm 214 can be divided into at least two parallel sub-channels 216. The second arm 215 can be formed by a single conduit 217.

[0132] The first arm 214 can be separated from the second arm 215 by a first wall 253 extending away from the end of the U-shaped flow path. At least two sub-channels 216 can be separated from each other by a second wall 254 extending away from the end of the U-shaped flow path. The first wall 253 can extend further away from the end of the U-shaped flow path than the second wall 254. Preferably, at least two parallel sub-channels 216 terminate at a common fluid opening 250.

[0133] In the illustrated embodiment, the second forming plate 222 may include a stamping recess 218, which together with the surface of the second plate 221 forms a second tube channel 2203. The stamping recess 218 may have a flat surface at the bottom and be positioned away from the second plate 221.

[0134] In the illustrated embodiment, the second forming plate 222 includes a fluid opening 250 for fluid to allow fluid to flow into and out of the second pipe 220, while the second plate 221 lacks any fluid opening 250 for fluid.

[0135] As described above, the inlet sleeve 251 and outlet sleeve 252 for the heat exchange fluid can be attached to the opening 250 of the first pipe 210.

[0136] Figure 21 An example of a first tube 210 having attachments 300 is shown. The first tube 210 includes a first shaped plate 212, which allows a first tube channel 2103 to be defined together with a first flat plate 211. Typically, the first tube channel 2103 may have a channel wall 219 formed by any heat exchange plate 201 (in this case, the first shaped plate 212). One or more attachments 300 may be attached to this channel wall 219. The attachments 300 typically have a bottom side 302 and a top side 303 (e.g., ...). Figure 23 (As shown). The attachment 300 can be connected to the channel wall 219 via the bottom side 302.

[0137] The attachment 300 may have a single contact portion 305 or multiple contact portions 305 extending away from the top side 303, preferably independently of each other. The contact portion 305 is understood herein as a dedicated portion of the attachment 300 designed to contact a specific heat source, allowing for convenient heat exchange between them. The contact portion 305 is designed to receive the majority of energy from the heat source, compared to portions of the attachment 300 where no contact portion 305 is present.

[0138] like Figures 20 to 28 As shown, the attachment 300 has an attachment substrate 301 extending within the base plane BP. The thickness T is defined as extending between the bottom side 302 and the top side 303 of the attachment substrate 301. The attachment substrate 301 may have a rectangular elongated profile extending along the attachment longitudinal axis L1 and the attachment transverse axis L2, with the extension along the attachment longitudinal axis L1 being the primary extension direction.

[0139] Figure 22 An example of an attachment 300 with two contact portions 305 is shown. The contact portions 305 extend perpendicularly to the base plane BP away from the top side 303.

[0140] In one embodiment, the attachment substrate 301 and the contact portion 305 are a single machined part. Alternatively, the contact portion 305 can be attached to the attachment substrate 301 by adhesive. Preferably, the plurality of contact portions 305 are made of a solid material. Preferably, the attachment 300 is made of a material with high thermal conductivity. Preferably, the attachment 300 and the contact portion 305 are made of metal. In this case, the contact portion 305 can be attached to the attachment substrate 301 by brazing.

[0141] In the illustrated embodiment, a gap section 304 exists between the contact portions 305. Here, the gap section 304 is a region of the substrate 301, particularly the region of its top side 303, where the contact portions 305 are absent. The gap section 304 can reduce the amount of material required for the attachment 300 in regions farther from the heat source than the contact portions 305. However, the gap section 304, particularly the region of the attachment substrate 301 at its bottom side 302, can help to securely attach the attachment 300 to any heat exchange plate 201 (in these cases, the first plate 211, the first forming plate 212, the second plate 221, and the second forming plate 222) by ensuring sufficient contact surface between the attachment 300 and the heat exchange plate 201.

[0142] In any case, the contact portions 305 preferably have a contact surface with an intermediate surface suitable for the heat source they will face, in order to maximize heat exchange efficiency. Preferably, the contact portions 305 have a flat top contact surface 306, especially when they are matched with integrated circuits that themselves tend to have flat surfaces.

[0143] Any contact portion 305 may have a rectangular profile, such as a square profile (e.g.) Figure 21 , 22 (as shown) or circular outline, such as ellipse or circle (as shown) Figure 26 As shown), the outline extends in its width and length dimensions.

[0144] Figure 23 Another example of the attachment 300 is shown. In this case, the two contact portions 305 are identical to each other and separated by a spacer segment 304. It is worth noting that the spacer segment 304 can exist between any edge of the contact portion 305 and the attachment substrate 301, and not just strictly between the contact portions 305.

[0145] Figure 24An example of a second tube 220 with attachments 300 is shown. The second tube 220 includes a second forming plate 222, which allows a second tube channel 2203 to be defined together with a second flat plate 221. Typically, the second tube channel 2203 may have a channel wall 219 formed by any heat exchange plate 201 (in this case, the second forming plate 222). One or more attachments 300 may be attached to this channel wall 219, for example, similar to those previously described with respect to the first tube 210.

[0146] Figure 25 Another example of an attachment 300 is shown. In this case, an attachment 300 for a second tube 220 is presented, which includes a plurality of contact portions 305. The presented contact portions 305 may differ from one another in size and shape to accommodate heat sources of different shapes and sizes, in this case a third heat source 431. The nature of the envisioned differences will be explained in conjunction with the following figures.

[0147] Figure 27 Schematic detail shown Figure 25 A partial side view of the attachment 300. The top side 303 may have a spacer segment 304 between adjacent contact portions 305, the spacer segment 304 maintaining a thickness T.

[0148] In one embodiment, at least one contact portion 305 extends further from the attachment substrate 301 than the other contact portion 305. In other words, one contact portion 305 may have a different height than the other contact portion 305.

[0149] In one embodiment, at least one contact portion 305 has a longitudinal length Lg that is different from that of another contact portion 305, the longitudinal length Lg being measured along the attachment longitudinal axis L1.

[0150] The top side 303 of the attachment substrate 301 and the flat top contact surface 306 of the contact portion 305 can be connected by a sidewall 307 of the contact portion 305, which is perpendicular to the top side 303 and the flat top contact surface 306. Alternatively, the sidewall 307 may be inclined relative to the top side 303 and / or the flat top contact surface 306.

[0151] Figure 28 Schematic detail shown Figure 25 Another side view of the attachment 300. At least one contact portion 305 may have a different lateral length Lt from the other contact portion 305, the lateral length Lt being measured along the attachment lateral axis L2.

[0152] Figure 27An example of a partial cross-sectional view of a heat exchange plate 201 having an attachment 300 is schematically shown. The attachment plate 301 may have a connection 308 suitable for riveting. As previously described, the top side 303 of the attachment plate 301 may have a spacer section 304 between contact portions 305, the spacer section 304 maintaining the thickness T of the attachment plate 301. The attachment plate 301 may be riveted at the spacer section 304 to the channel wall 219 of any heat exchange plate 201 (e.g., first plate 211, first forming plate 212, second plate 221, second forming plate 222) by a riveting connection 309. This riveting connection 309 may be an intermediate step for attaching the attachment 300 to any heat exchange plate 201, which may then be finally secured by brazing. In this case, the riveting connection 309 is used to position the components relative to each other, allowing the brazing process to be performed efficiently.

[0153] Figure 30 It shows Figure 20 A cross-sectional view of the first tube 210. A baffle 270 for improving heat exchange efficiency can be placed within the first tube channel 2103. It can exist in a selected arm 214, conduit 217, or sub-channel 216 of the first tube channel 2103, or they can be filled simultaneously. With necessary modifications, this also applies to the second tube 220 or other tubes (if present).

[0178] As shown in the figure, interconnect 260 is a rigid element, enabling a safe and stable connection to any external connector 3001, 3002. Furthermore, interconnect 260 serves as a rigid element to interconnect the tubes 210, 220, 230 of the heat exchanger 200. This interconnect 260 is easy to manufacture and can be adjusted as needed. It can be used as an independent attachment point for external connectors 3001, 3002.

[0179] Due to the proper placement and sizing of the recesses 2701, 2702, 2703, 2704, and 2705, the interconnector 260 can be configured to be partially or entirely placed between tubes 210, 220, or 230.

[0180] With separate collar plates 3001 and 3002, the main body 261 can be less complex and easier to manufacture.
