[0033] The existing radiator designs are basically "vertical", "horizontal" or "front and back rows". The above structures are not compact enough and require a large installation space. In particular, when two or more different media need to be cooled at the same time, multiple radiators are usually used to cool them separately. In this way, multiple radiators need to be assembled separately. On the one hand, the difficulty of assembly is increased. On the other hand, the required installation space is large, which is not conducive to the miniaturization of the entire cooling system. In particular, vehicles and some industrial equipment have an urgent need for miniaturization.

[0034] See also Figure 1-Figure 4 In order to solve the problem that the heat dissipation of multiple different media requires the use of multiple different radiators for heat dissipation, which leads to complicated assembly procedures and large space occupation, the present application provides an integrated heat exchange device, which includes a plurality of heat exchange parts 100 stacked and connected along the thickness direction thereof, the heat exchange part 100 includes fins 110, a liquid inlet pipe 120, a liquid outlet pipe 130, and a liquid inlet manifold 140, a diverter pipe 160 and a liquid outlet manifold 150 sequentially arranged and connected along the length direction thereof, the liquid inlet pipe 120 is connected to the liquid inlet manifold 140 to input the medium into the liquid inlet manifold 140, the liquid outlet pipe 130 is connected to the liquid outlet manifold 150, and the liquid outlet manifold 150 outputs the medium through the liquid outlet pipe 130.

[0035] Specifically, in one embodiment, adjacent heat exchange parts 100 may be connected by welding, clamping or integrally casting adjacent liquid inlet headers 140 , and adjacent liquid outlet headers 150 may be welded, clamped or integrally cast.

[0036] In other embodiments, the connection between adjacent heat exchange parts 100 may also be arranged by welding, clamping or integrally casting the correspondingly arranged shunt pipes 160 .

[0037] Alternatively, adjacent heat exchange parts 100 may be connected and fixed together by welding connecting plates on the sides of the integrated heat exchange device.

[0038] Of course, the connection between adjacent heat exchange parts 100 can also be a combination of the above multiple connection methods.

[0039] A plurality of manifolds 160 are sequentially arranged along the width direction of the heat exchange part 100, and adjacent manifolds 160 are spaced apart to form a heat exchange gap, and the fins 110 are disposed in the heat exchange gap, and both ends of the fins 110 are respectively connected to adjacent manifolds 160, so that heat can be mutually transferred between the manifolds 160 and the heat exchange fins 110. In addition, the heat exchange gaps of adjacent heat exchange parts 100 are correspondingly disposed and connected, so that the external airflow can sequentially pass through the heat exchange gaps of adjacent heat exchange parts 100 along the thickness direction of the heat exchange part 100.

[0040] It should be noted that the heat exchange unit 100 is in the shape of a plate with a certain thickness, similar to a plate heat exchanger. When the heat exchange unit 100 is arranged vertically, the three-dimensional directions of the heat exchange unit 100 are the height direction, the width direction and the thickness direction. Of course, when the heat exchange unit 100 is arranged horizontally, the height direction can also be defined as the length direction, and there is no essential difference between the two. Therefore, "a plurality of heat exchange units 100 are stacked along their own thickness direction" means that a plurality of heat exchange units 100 are attached and integrated together along their own thickness direction.

[0041] like Figure 1 As shown, in Figure 1 Detailed description is given of the length direction X, width direction Y, and thickness direction Z of the heat exchange unit 100.

[0042] In this way, the integrated heat exchange device integrates multiple heat exchange parts 100 together to achieve heat exchange of multiple different cooling media at the same time without affecting each other. Multiple heat exchange parts 100 are connected and arranged, so during the installation process, there is no need to assemble each heat exchange part 100 separately, which greatly reduces the difficulty of assembly.

[0043] Furthermore, since the plurality of heat exchange parts 100 are stacked in the thickness direction, the entire integrated heat exchange device is arranged compactly, which can effectively improve the space utilization of the entire integrated heat exchange device.

[0044] Furthermore, since the heat exchange gaps of adjacent heat exchange parts 100 are correspondingly arranged and connected, and the external airflow can sequentially pass through the heat exchange gaps of adjacent heat exchange parts 100 along the thickness direction of the heat exchange part 100, when installing the integrated heat exchange device, only one airflow channel needs to be arranged to complete the heat exchange of the entire integrated heat exchange device, thereby greatly reducing the installation space required for the integrated heat exchange device.

[0045] In one embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the liquid inlet pipe 120 is provided with a first extension section 121 extending toward the adjacent heat exchange part 100, and the liquid inlet pipe 120 is connected to the liquid inlet manifold 140 of the adjacent heat exchange part 100 through the first extension section 121, that is, the liquid inlet pipe 120 is not only connected to the corresponding liquid inlet manifold 140, but also connected to the adjacent heat exchange part 100.

[0046] Obviously, such a configuration can, on the one hand, effectively improve the installation strength of the liquid inlet pipe 120, and on the other hand, can improve the assembly strength of the adjacent heat exchange part 100, that is, can improve the assembly strength of the entire integrated heat exchange device.

[0047] Furthermore, in one embodiment, the first extension section 121 is welded or clamped to the liquid inlet manifold 140 of the adjacent heat exchange portion 100 .

[0048] It should be noted that, for the sake of welding firmness, in one embodiment, the first extension section 121 and the liquid inlet pipe 120 are integrally formed, and the first extension section 121 is respectively provided with a groove adapted to the shape of the adjacent liquid inlet pipe 120 .

[0049] However, the present invention is not limited thereto. In other embodiments, the first extension section 121 may also be sleeved on and welded to the outer peripheral side of the liquid inlet pipe 120 .

[0050] Such an arrangement can reduce the difficulty of processing the first extension section 121 and the liquid inlet pipe 120 .

[0051] Likewise, if Figure 1 , Figure 2 and Figure 4 As shown, the liquid outlet pipe 130 is provided with a second extension section 131 extending toward the adjacent heat exchange part 100, and the liquid outlet pipe 130 is connected to the liquid outlet manifold 150 of the adjacent heat exchange part 100 through the second extension section 131, that is, the liquid outlet pipe 130 is not only connected to the corresponding liquid outlet manifold 150, but also connected to the adjacent heat exchange part 100.

[0052] Obviously, such a configuration can, on the one hand, effectively improve the installation strength of the liquid outlet pipe 130, and on the other hand, can improve the assembly strength of the adjacent heat exchange part 100, that is, can improve the assembly strength of the entire integrated heat exchange device.

[0053] Furthermore, in one embodiment, the second extension section 131 is welded or clamped to the liquid outlet manifold 150 of the adjacent heat exchange portion 100 .

[0054] It should be noted that, for the sake of welding firmness, in one embodiment, the second extension section 131 and the liquid outlet pipe 130 are integrally formed, and the second extension section 131 is respectively provided with a groove adapted to the shape of the adjacent liquid outlet pipe 130 .

[0055] However, the present invention is not limited thereto. In other embodiments, the second extension section 131 may also be sleeved on and welded to the outer peripheral side of the liquid outlet pipe 130 .

[0056] Such an arrangement can reduce the difficulty of processing the second extension section 131 and the liquid outlet pipe 130 .

[0057] In one embodiment, if Figure 2 As shown, the liquid inlet manifold 140 includes a liquid inlet main section 141, a first end cover 142 and a second end cover 143, a plurality of branch pipes 160 are respectively inserted and connected to the liquid inlet main section 141, and the first end cover 142 and the second end cover 143 are respectively sealed and arranged at both ends of the liquid inlet main section 141.

[0058] Such a configuration is helpful to reduce the difficulty of processing the liquid inlet manifold 140 .

[0059] However, it is not limited thereto. In other embodiments, the liquid inlet manifold 140 may also be an integrally formed setting, such as an integrally stamped setting, an integrally cast setting, or an integrally 3D printed setting.

[0060] In one embodiment, if Figure 2 As shown, the liquid outlet manifold 150 includes a liquid outlet main section 151, a third end cover 152 and a fourth end cover 153, a plurality of branch pipes 160 are respectively inserted and connected to the liquid outlet main section 151, and the third end cover 152 and the fourth end cover 153 are respectively sealed and arranged at both ends of the liquid outlet main section 151.

[0061] Such an arrangement is helpful to reduce the difficulty of processing the liquid outlet manifold 150 .

[0062] However, it is not limited thereto. In other embodiments, the liquid outlet manifold 150 may also be an integrally formed setting, such as an integrally stamped setting, an integrally cast setting, or an integrally 3D printed setting.

[0063] In one embodiment, if Figure 1-Figure 4As shown, the integrated heat exchange device also includes a liquid inlet connecting pipe 400, a liquid inlet sealing plug 310, a liquid outlet connecting pipe 500 and a liquid outlet sealing plug 320. The heat exchange part 100 provided with the liquid inlet sealing plug 310 and the liquid outlet sealing plug 320 is defined as the adjusting part 300, and the heat exchange part 100 not provided with the liquid inlet sealing plug 310 and the liquid outlet sealing plug 320 is defined as the fixing part 200.

[0064] A liquid inlet sealing plug 310 is provided in the liquid inlet collecting pipe 140 of the regulating part 300, and the liquid inlet sealing plug 310 separates the liquid inlet collecting pipe 140 of the regulating part 300 into a first liquid inlet section 330 and a second liquid inlet section 340 which are not connected. The liquid inlet connecting pipe 400 is arranged at one end of the integrated heat exchange device along its own width direction, and the liquid inlet connecting pipe 400 connects the first liquid inlet section 330 of the regulating part 300 and the liquid inlet collecting pipe 140 of the adjacent fixed part 200.

[0065] It should be noted that the first liquid inlet section 330 and the second liquid inlet section 340 can be configured by welding in sections or by integrally forming.

[0066] Specifically, the two ends of the liquid inlet connecting pipe 400 may be respectively welded to the first liquid inlet section 330 and the liquid inlet manifold 140 of the adjacent fixed portion 200 , or may be respectively clamped to the first liquid inlet section 330 and the liquid inlet manifold 140 of the adjacent fixed portion 200 .

[0067] A liquid outlet sealing plug 320 is provided in the liquid outlet collecting pipe 150 of the regulating part 300, and the liquid outlet sealing plug 320 separates the liquid outlet collecting pipe 150 of the regulating part 300 into a first liquid outlet section 350 and a second liquid outlet section 360 which are not connected. The liquid outlet connecting pipe 500 is arranged at one end of the integrated heat exchange device along its own width direction, and the liquid outlet connecting pipe 500 and the liquid inlet connecting pipe 400 are arranged at the same end of the integrated heat exchange device, and the liquid outlet connecting pipe 500 connects the first liquid outlet section 350 of the regulating part 300 and the liquid outlet collecting pipe 150 of the adjacent fixed part 200.

[0068] It should be noted that the first liquid outlet section 350 and the second liquid outlet section 360 may be welded in sections or may be integrally formed.

[0069] Specifically, both ends of the liquid outlet connecting pipe 500 may be respectively welded to the first liquid outlet section 350 and the liquid outlet manifold 150 of the adjacent fixing portion 200 , or may be respectively clamped to the first liquid outlet section 350 and the liquid outlet manifold 150 of the adjacent fixing portion 200 .

[0070] The first liquid inlet section 330 and the first liquid outlet section 350 are arranged correspondingly, that is, the two are arranged at the same end of the integrated heat exchange device and the lengths of the two are basically equal. The first liquid inlet section 330 is connected to the corresponding first liquid outlet section 350 through one or more corresponding shunt pipes 160, and the second liquid inlet section 340 is connected to the corresponding second liquid outlet section 360 through one or more corresponding shunt pipes 160.

[0071] With such arrangement, when the flow rate of one medium is larger and the flow rate of the other medium is smaller, the medium with a larger flow rate can not only be heat exchanged through the fixed part 200, but the excess medium can also enter the first liquid inlet section 330 of the adjacent regulating part 300 through the liquid inlet connecting pipe 400, and then enter the corresponding first liquid outlet section 350 through the diverter pipe 160, and finally enter the liquid outlet collecting pipe 150 of the fixed part 200 through the liquid outlet connecting pipe 500, thereby completing the heat exchange of the medium.

[0072] Correspondingly, the medium with a smaller flow rate directly enters the second liquid outlet section 360 through the second liquid inlet section 340 of the regulating part 300 and the corresponding diverter pipe 160 to complete its own heat exchange.

[0073] From the above, it can be seen that such a configuration can increase or decrease the flow area of ​​the medium according to the flow rate of different media, thereby increasing or decreasing the heat exchange area of ​​the medium, thereby improving the overall heat exchange efficiency of the integrated heat exchange device.

[0074] Furthermore, in one embodiment, the liquid inlet sealing plug 310 and the inner wall of the liquid inlet manifold 140 of the regulating part 300 are movably sealed together, and the liquid outlet sealing plug 320 and the inner wall of the liquid outlet manifold 150 of the regulating part 300 are movably sealed together.

[0075] In this way, the relative lengths of the first liquid inlet section 330 and the second liquid inlet section 340 can be adjusted according to the change of the medium flow rate, that is, the length of the first liquid inlet section 330 along the width direction of the integrated heat exchange device can be increased, and the length of the second liquid inlet section 340 along the width direction of the integrated heat exchange device can be reduced, or the length of the first liquid inlet section 330 along the width direction of the integrated heat exchange device can be reduced, and the length of the second liquid inlet section 340 along the width direction of the integrated heat exchange device can be increased.

[0076] Such an arrangement greatly improves the adjustment flexibility of the adjustment portion 300 .

[0077] It should be noted that the liquid inlet sealing plug 310 and the liquid outlet sealing plug 320 are sealing plugs that can withstand high pressure. Specifically, the materials of the liquid inlet sealing plug 310 and the liquid outlet sealing plug 320 include but are not limited to rubber, silicone, polytetrafluoroethylene (PTFE), polyimide (PI), polypropylene (PP) and polyurethane (PU), etc., which are not listed here one by one.

[0078] But not limited to this, in other embodiments, the liquid inlet sealing plug 310 and the inner wall of the liquid inlet collecting pipe 140 of the regulating part 300 are fixedly sealed and connected, and the liquid outlet sealing plug 320 and the inner wall of the liquid outlet collecting pipe 150 of the regulating part 300 are fixedly sealed and connected.

[0079] It should be noted that the fixed sealing connection includes various connection methods such as welding, clamping or 3D printing molding settings.

[0080] Such an arrangement can effectively improve the installation strength of the liquid inlet sealing plug 310 and the liquid outlet sealing plug 320, thereby increasing the service life of the integrated heat exchange device.

[0081] Furthermore, in one embodiment, the integrated heat exchange device also includes a first motor (not shown) and a second motor (not shown), the first motor is connected to the liquid inlet collecting pipe 140 of the regulating part 300, the liquid inlet sealing plug 310 is connected to the output end of the first motor and is coaxially arranged with the output shaft of the first motor, the liquid inlet sealing plug 310 and the inner wall of the liquid inlet collecting pipe 140 of the regulating part 300 are engaged with each other by movable threads, and the output shaft of the first motor can drive the liquid inlet sealing plug 310 to rotate, so that the liquid inlet sealing plug 310 moves along the axial direction of the liquid inlet collecting pipe 140 (the width direction of the heat exchange part 100), thereby changing the relative lengths of the first liquid inlet section 330 and the second liquid inlet section 340.

[0082] It should be noted that the connection method of the movable thread is based on the same principle as the ordinary thread connection. This method can achieve sealing mainly by utilizing the tension and viscosity of the liquid. In addition, under the layer-by-layer sealing effect of multiple turns of threads, the sealing between the liquid inlet sealing plug 310 and the inner wall of the liquid inlet collecting pipe 140 is greatly enhanced. Therefore, the movable thread seal has a better sealing effect.

[0083] The second motor is connected to the liquid outlet collecting pipe 150 of the regulating part 300, and the liquid outlet sealing plug 320 is connected to the output end of the second motor and is coaxially arranged with the output shaft of the second motor. The liquid outlet sealing plug 320 and the inner wall of the liquid outlet collecting pipe 150 of the regulating part 300 are engaged with movable threads. The output shaft of the second motor can drive the liquid outlet sealing plug 320 to rotate, so that the liquid outlet sealing plug 320 moves along the axial direction of the liquid outlet collecting pipe 150 (the width direction of the heat exchange part 100), thereby changing the relative length of the second liquid outlet section 360 and the second liquid outlet section 360.

[0084] It should be noted that the first motor and the second motor can be micromotors, where the full name of micromotor is "micro electric motor", which refers to a motor with a diameter less than 160 mm or a rated power less than 750 mW. Of course, depending on the actual pipe diameter, the first motor and the second motor can also be motors with a diameter greater than or equal to 160 mm or a rated power greater than or equal to 750 mW.

[0085] Such an arrangement enables precise adjustment of the liquid inlet sealing plug 310 and the liquid outlet sealing plug 320 .

[0086] But not limited thereto, in other embodiments, the liquid inlet sealing plug 310 and the inner wall of the liquid inlet manifold 140 of the regulating portion 300 are slidably matched along the width direction of the heat exchange portion 100 .

[0087] In this way, when the hydraulic pressure of the first liquid inlet section 330 is not equal to the hydraulic pressure of the second liquid inlet section 340, the medium on the side with larger hydraulic pressure can drive the liquid inlet sealing plug 310 to move toward the side with smaller hydraulic pressure, and finally achieve hydraulic balance on both sides of the liquid inlet sealing plug 310.

[0088] Similarly, the liquid outlet sealing plug 320 and the inner wall of the liquid outlet manifold 150 of the regulating part 300 are slidably matched along the width direction of the heat exchange part 100 .

[0089] In this way, when the hydraulic pressure of the first liquid outlet section 350 is not equal to the hydraulic pressure of the second liquid outlet section 360, the medium on the side with greater hydraulic pressure can drive the liquid outlet sealing plug 320 to move toward the side with less hydraulic pressure, and finally achieve hydraulic balance on both sides of the liquid outlet sealing plug 320.

[0090] Obviously, the above adjustment method is simpler and is conducive to reducing the manufacturing cost of the integrated heat exchange device.

[0091] In one embodiment, if Figure 1-Figure 3 As shown, the integrated heat exchange device also includes a liquid inlet support ring 210 and a liquid outlet support ring 220. The liquid inlet support ring 210 is arranged on the liquid inlet manifold 140 of the fixed part 200 to support the tube wall, and the liquid outlet support ring 220 is arranged on the liquid outlet manifold 150 of the fixed part 200 to support the tube wall.

[0092] In one embodiment, if Figure 1-Figure 4 As shown, the integrated heat exchange device includes two heat exchange parts 100 , one of the heat exchange parts 100 is an adjustment part 300 , and the other is a fixing part 200 .
