[0015] According to one possible embodiment of the thermal management device of this application, referencing Figures 1 to 7As shown, a thermal management device includes a flow channel plate 10 and a first shut-off valve assembly 20. The first shut-off valve assembly 20 includes a first on / off valve 21 and a first nut connector 22, which are separately disposed. The flow channel plate 10 includes a first mounting portion 11 and a first interface portion 12. The first on / off valve 21 is fixedly connected to the first mounting portion 11, and the first nut connector 22 is fixedly connected to the first interface portion 12.

[0016] The flow plate 10 has multiple flow channels 101, the first ferrule 22 has a first external channel 221, and the first on / off valve 21 can control the on / off connection between the first external channel 221 and at least one flow channel 101.

[0017] In this application, the first shut-off valve assembly 20 includes a first on / off valve 21 and a first ferrule connector 22. The flow channel plate 10 has multiple flow channels 101, and the first ferrule connector 22 has a first external connection channel 221. The first on / off valve 21 can control the on / off connection between the first external connection channel 221 and at least one flow channel 101. The first on / off valve 21 and the first ferrule connector 22 are two separate components. By combining the first on / off valve 21 and the first ferrule connector 22, a conventional shut-off valve can be replaced, which is relatively easier to assemble and manufacture, and has a relatively lower cost.

[0018] The first mounting part 11 has a first mounting cavity 111, and a portion of the first on / off valve 21 is located in the first mounting cavity 111. The first on / off valve 21 is directly connected to the first mounting part 11. The first on / off valve 21 is directly connected to the first mounting part 11 of the flow channel plate 10. Compared with the related technology where the shut-off valve is fixedly connected to the flow channel plate 10 through a pipeline, the volume of the thermal management device can be reduced.

[0019] Reference Figure 1 , Figure 4 and Figure 5The first on / off valve 21 includes a first valve stem 211, a first valve body 212, and a first sealing element 213. The first valve stem 211 and the first valve body 212 are connected. A portion of the first valve stem 211 is located within the inner cavity of the first valve body 212, and at least a portion of the first valve body 212 is located within the first mounting cavity 111. The first sealing element 213 is sleeved on the peripheral wall of the first valve body 212. The first valve body 212 and the cavity wall of the first mounting cavity 111 are sealed together by the first sealing element 213. The outer peripheral wall of the first valve body 212 and the cavity wall of the first mounting cavity 111 are also sealed together by the first sealing element 213. Specifically, the first sealing element 213 is located between the outer peripheral wall of the first valve body 212 and the cavity wall of the first mounting cavity 111, and both the outer peripheral wall of the first valve body 212 and the cavity wall of the first mounting cavity 111 elastically abut against the first sealing element 213. The first sealing element 213 is an O-ring made of rubber. Ensuring the sealing between the first valve body 212 and the flow channel plate 10 guarantees the sealing between the first on / off valve 21 and the flow channel plate 10, reducing the possibility of fluid leakage.

[0020] The thermal management device includes a first multi-way valve 50, which is a pipeline-type four-way valve. The first multi-way valve 50 is fixedly connected to a flow channel plate 10. A first valve body 212 has a first valve port 2121 and a second valve port 2122, both located in a first mounting cavity 111. A first valve stem 211 controls the on / off connection between the first valve port 2121 and the second valve port 2122. The flow channel plate 10 has a first flow channel 1011. The first valve port 2121 communicates with a first external channel 221, and the second valve port 2122 communicates with the inner cavity of the first multi-way valve 50 through the first flow channel 1011. The first on / off valve 21 also includes a first valve core. The first valve stem 211 is throttle-connected to the first valve core. Rotating the first valve stem 211 drives the first valve core to move, thereby controlling the on / off connection between the first valve port 2121 and the second valve port 2122.

[0021] The first on / off valve 21 includes a first connecting ring 214, which is circular and made of metal. The first connecting ring 214 is sleeved on the peripheral sidewall of the first valve body 212. The first mounting part 11, the first connecting ring 214, and the first valve body 212 are mutually restrictive and fitted together. The first connecting ring 214 is fixedly connected to the first mounting part 11 by bolts. Specifically, the first connecting ring 214 has multiple first bolt holes, which are evenly spaced along the circumference of the first connecting ring 214. The first mounting part 11 has multiple second bolt holes, which are also evenly spaced along the circumference of the first connecting ring 214. The first bolt holes correspond to the second bolt holes. The fixed connection between the first connecting ring 214 and the first mounting part 11 by bolts improves the connection stability and sealing between the first on / off valve 21 and the flow channel plate 10, and also facilitates the disassembly and subsequent maintenance of the first on / off valve 21 and the flow channel plate 10.

[0022] In an optional embodiment, the first on / off valve 21 and the flow channel plate 10 are connected by laser welding, which is conducive to industrial production, has low cost, and good sealing performance.

[0023] Reference Figure 1 , Figure 4 and Figure 5 The first connector 22 includes a first tube body 222 and a first external nut 223. The first tube body 222 is connected to the first interface 12. The first tube body 222 and the first external nut 223 are sealed together. The first tube body 222 and the first external nut 223 are detachably connected. Both the first tube body 222 and the first external nut 223 are made of brass and have excellent corrosion resistance.

[0024] In an optional embodiment, the first shut-off valve assembly 20 further includes a first filling component, which is fixedly connected to the flow channel plate 10. The first filling component has a first filling channel and includes a first valve core installed in the first filling channel. The first on / off valve 21 can control the on / off of the first flow channel 1011, the first filling channel, and the first external channel 221.

[0025] The first valve core is used to charge the working medium, such as refrigerant, into the thermal management system, ensuring its normal operation. It can also regulate system pressure to some extent; for example, if the system pressure is too low, charging an appropriate amount of medium can increase the pressure and maintain stability. The first valve core controls the charging and shut-off of the medium. During charging, external force is applied to overcome the tension of the internal spring, opening the sealing gasket and providing a passage for the refrigerant to enter the system. After charging, the external force is removed, and the sealing gasket adheres tightly to the valve seat under the spring's action, preventing backflow and shutting off the first charging channel, ensuring no leakage of the medium within the system. It also allows for precise adjustment of the charging amount and convenient pressure testing. By connecting a specialized pressure testing device to the first valve core, the internal pressure of the system can be quickly and easily measured, verifying the charging effect and the system's sealing performance. It also facilitates system maintenance. After the system has been repaired, maintained, or had parts replaced, it is necessary to re-vacuum and refill the medium. The first valve core provides a dedicated and easy-to-use interface, which enables these maintenance tasks to be carried out smoothly.

[0026] The first filling component includes a first filling valve cap and a first filling tube section, which are detachably connected. The first filling valve is sealed to the first filling tube section to ensure a tight seal. A first filling channel is located in the first filling tube section, and the first filling valve cap is used to protect components such as the first valve core.

[0027] The flow channel plate 10 is a one-piece structure. In this embodiment, the flow channel plate 10 is manufactured using a traditional one-piece casting process. Straight flow channels are formed in the flow channel plate 10 through machining, resulting in good structural strength and sealing performance; the machining technology is mature.

[0028] In an optional embodiment, the flow channel plate 10 is a one-piece structure, manufactured using sand core casting technology, specifically a one-piece sand core casting process. One-piece sand core casting is a casting process that forms complex internal cavities or flow channels in a casting by pre-placed sand cores. This process utilizes the high-temperature resistance and plasticity of sand cores to create complex geometries within the casting, such as curved flow channels, porous structures, or branching channels.

[0029] The flow channel plate 10 is manufactured using a sand core integral casting process. The manufacturing steps are as follows:

[0030] Based on the internal structure of the flow channel plate 10 and the design requirements of the flow channel 101, a three-dimensional model of the sand core was designed using CAD software.

[0031] Resin sand or water glass sand is pressed into shape using a core shooter. Alternatively, 3D printing technology, such as binder jetting, can be used to directly manufacture complex sand cores with higher precision.

[0032] Applying refractory coatings, such as graphite coatings, to the surface of sand cores improves surface smoothness and heat resistance.

[0033] Secure the sand core in the mold to ensure accurate positioning, such as by using locating pins or support structures for positioning and support.

[0034] The mold material is usually wet sand or resin sand, suitable for pouring high-temperature molten metal. Molten metal, such as aluminum alloy, cast iron, and stainless steel, is poured into the mold to fill the cavity around the sand core.

[0035] After cooling, the sand core is removed from the casting by vibration, high-pressure water impact, or chemical dissolution;

[0036] Clean the surface of the casting to remove residual sand particles, perform shot blasting or sandblasting, and high-pressure clean the internal cavities to ensure no sand particles remain. This completes the manufacturing of the flow channel plate 10.

[0037] The flow channel plate 10 is manufactured using a sand core integrated casting process, enabling the creation of complex flow channels 101 such as curved, spiral, and branched structures to meet the needs of efficient heat exchange or fluid control. Integrated molding avoids sealing issues associated with welding or assembly. The sand core shape is flexible, supporting customized designs to adapt to diverse application scenarios. Compared to machining or welding, sand core integrated casting reduces material waste and lowers production costs. It is suitable for a wide range of metal materials, including aluminum alloys, cast iron, copper alloys, and stainless steel. The sand core surface is coated with a refractory coating to improve the flow channel smoothness and reduce subsequent machining requirements. 3D printing sand core technology enables high-precision molding of complex structures. In short, the flow channel plate 10 is manufactured using a sand core integrated casting process, achieving the molding of complex internal structures through pre-placed sand cores, offering high design freedom, good sealing, and good structural strength.

[0038] In an optional embodiment, the flow channel plate 10 is a split structure, comprising a first plate and a second plate, which are fixedly connected. The flow channel 101 is located between the first plate and the second plate. The first plate and / or the second plate have multiple grooves or holes forming the flow channel 101. Specifically, the first plate and the second plate are welded together to achieve a sealed connection.

[0039] Optionally, the first plate and / or the second plate are stamped parts, manufactured using a stamping process. Both the first plate and the second plate are stamped parts, and both have multiple slots or holes forming the flow channel 101.

[0040] Specifically, metal sheets, such as stainless steel or aluminum alloy, with thicknesses ranging from 0.02mm to 1mm, are selected. The sheets are then punched, stretched, or bent on a press using molds to form the basic outline of the flow channel 101. Stamping can efficiently process complex shapes, such as spirals, bends, and branching flow channels, completing hundreds to thousands of stamping operations per minute. The flow channel surface requires further reaming and polishing to ensure smoothness and reduce fluid pressure drop. The flow channel plate 10 is manufactured using a stamping process, enabling efficient production, high precision, and complex flow channel forming. Furthermore, the flow channel plate 10 is lightweight, resulting in lower material and processing costs.

[0041] Optionally, the first and second plates are manufactured using traditional casting processes. Specifically, the first plate is cast and then machined to form the internal flow channels 101. The second plate is a flat plate structure, and the first and second plates are welded together.

[0042] The flow channel plate 10 has multiple flow channels 101, at least one of which is a curved flow channel. At least one flow channel 101 is either a curved or spiral flow channel. When the flow channel 101 is curved, the fluid's direction constantly changes, generating centrifugal force that causes the fluid particles to collide and mix, thus forming strong turbulence. Compared to straight flow channels, turbulence significantly improves the convective heat transfer coefficient of the fluid. The curved shape increases the surface area of ​​the flow channel 101, thereby increasing the contact area between the fluid and the wall of the flow channel 101. A larger contact area means more heat can be transferred in the same amount of time, improving the heat exchange efficiency of the entire thermal management device. The curved flow channel 101 reduces flow resistance compared to a flow channel with a right-angle turn.

[0043] Reference Figure 1 , Figure 4 and Figure 6 The thermal management device includes a second shut-off valve assembly 30 and a second multi-way valve 60. The second multi-way valve 60 is a pipeline-type three-way valve and is fixedly connected to the flow channel plate 10. The first multi-way valve 50 and the second multi-way valve 60 are located on opposite sides of the flow channel plate 10, resulting in a compact structure. The second shut-off valve assembly 30 includes a second on / off valve 31 and a second connector 32. The first connector 22 and the second connector 32 are located on the same side of the flow channel plate 10, facilitating installation and maintaining a compact structure.

[0044] The flow channel plate 10 includes a second mounting portion 13 and a second interface portion 14. A second connector 32 is connected to the second interface portion 14. The second mounting portion 13 has a second mounting cavity 131. A portion of the second on-off valve 31 is located in the second mounting cavity 131, and the second on-off valve 31 is directly connected to the second mounting portion 13. The flow channel plate 10 has a second flow channel 1012, which communicates with the inner cavity of the second multi-way valve 60. The second connector 32 has a second external connection channel 321, and the second on-off valve 31 can control the on / off connection between the second external connection channel 321 and the second flow channel 1012.

[0045] The combination of the second on / off valve 31 and the second ferrule 32 can replace the conventional shut-off valve, resulting in a relatively lower cost. Furthermore, a portion of the second on / off valve 31 is located in the second mounting cavity 131, and the second on / off valve 31 is directly connected to the second mounting portion 13 of the flow channel plate 10. Compared to the related technology where the shut-off valve is fixedly connected to the flow channel plate 10 via a pipeline, this reduces the size of the thermal management device.

[0046] The second on / off valve 31 includes a second valve stem 311, a second valve body 312, and a second sealing element 313. The second valve stem 311 and the second valve body 312 are connected. A portion of the second valve stem 311 is located within the inner cavity of the second valve body 312, and at least a portion of the second valve body 312 is located within the second mounting cavity 131. The second sealing element 313 is sleeved on the peripheral wall of the second valve body 312. The outer peripheral wall of the second valve body 312 is sealed to the cavity wall of the second mounting cavity 131 through the second sealing element 313. Specifically, the second sealing element 313 is located between the outer peripheral wall of the second valve body 312 and the cavity wall of the second mounting cavity 131, and both the outer peripheral wall of the second valve body 312 and the cavity wall of the second mounting cavity 131 elastically abut against the second sealing element 313. The second sealing element 313 is an O-ring made of rubber. This ensures the sealing between the second valve body 312 and the flow channel plate 10, thus ensuring the sealing between the second on / off valve 31 and the flow channel plate 10 and reducing the possibility of fluid leakage.

[0047] Reference Figure 1 , Figure 4 and Figure 6 The second on / off valve 31 includes a second connecting ring 314, which is circular and made of metal. The second connecting ring 314 is sleeved on the peripheral wall of the second valve body 312. The second mounting part 13, the second connecting ring 314, and the second valve body 312 are mutually restrictive and engaged. The second connecting ring 314 and the second mounting part 13 are fixedly connected by bolts.

The second mounting part 13 has multiple second bolt holes, which are also evenly spaced along the circumference of the second connecting ring 314. The first bolt holes correspond to the second bolt holes. The fixed connection between the second connecting ring 314 and the second mounting part 13 by bolts improves the connection stability and sealing between the second on / off valve 31 and the flow channel plate 10, and also facilitates the disassembly and subsequent maintenance of the second on / off valve 31 and the flow channel plate 10.

[0048] In an optional embodiment, the second on / off valve 31 is connected to the flow channel plate 10 by laser welding, which is conducive to industrial production, has low cost, and good sealing performance.

[0049] The second connector 32 includes a second tube body 322 and a second external nut 323. The second tube body 322 is connected to the second interface 14. The second tube body 322 and the second external nut 323 are sealed together. The second tube body 322 and the second external nut 323 are detachably connected. Both the second tube body 322 and the second external nut 323 are made of brass and have excellent corrosion resistance.

[0050] In an optional embodiment, the second shut-off valve assembly 30 further includes a second filling component, which is fixedly connected to the flow channel plate 10. The second filling component has a second filling channel and includes a second valve core installed in the second filling channel. The second on / off valve 31 can control the on / off connection between the second flow channel 1012, the second filling channel, and the second external channel 321.

[0051] The second valve core is used to charge the working medium, such as refrigerant, into the thermal management system, ensuring the system can operate normally and maintain stable system pressure. The second valve core controls the charging and shut-off of the medium, allowing for precise adjustment of the charging amount, convenient pressure testing, verification of the charging effect and system sealing, and also facilitating system maintenance.

[0052] The second filling component includes a second filling valve cap and a second filling pipe section. The second filling valve cap and the second filling pipe section are detachably connected. The second filling valve is sealed to the second filling pipe section to ensure a tight seal. The second filling channel is located in the second filling pipe section, and the second filling valve cap is used to protect components such as the second valve core.

[0053] Reference Figure 1 , Figure 4 and Figure 7 The thermal management device includes a first filter 70, which has a first filter chamber 701. The first filter 70 includes a first filter housing 71 and a first filter element 72. The first filter element 72 is located in the first filter chamber 701 and is limitedly connected to the first filter housing 71. The first filter chamber 701 is connected to the flow channel 101. The first filter housing 71 and the flow channel plate 10 are integral structures. Compared with the first filter 70 and the flow channel plate 10 being connected by pipes, this reduces pipe connections and welding points, reduces the possibility of fluid leakage, and has better structural pressure resistance.

[0054] The thermal management device includes a third shut-off valve assembly 40, which includes a third on / off valve 41, a third ferrule connector 42, and a mounting base 43. The third on / off valve 41 and the third ferrule connector 42 are both fixedly connected to the mounting base 43. The first ferrule connector 22 and the third ferrule connector 42 are located on the same side of the flow channel plate 10. The first filter 70 includes a first cover 73, which is fixedly connected to a first filter housing 71. Specifically, a portion of the first cover 73 is located in the first filter chamber 701, and the first cover 73 is welded to the first filter housing 71. During assembly, the first filter element 72 is first installed in the first filter chamber 701, then the first cover 73 partially extends into the first filter chamber 701, and then the first cover 73 is welded to the first filter housing 71 to achieve a fixed and sealed connection. The mounting base 43 is used for the installation of the third on / off valve 41 and the third ferrule connector 42. The first cover 73 and the mounting base 43 are an integral structure, reducing welding points, resulting in better structural stability and sealing. The third connector 42 has a third external channel 421, and the third on / off valve 41 can control the on / off connection between the third external channel 421 and the first filter chamber 701.

The third connecting ring 414 is sleeved on the peripheral side wall of the third valve body 412. The inner wall of the first assembly cavity 431, the third connecting ring 414, and the third valve body 412 are mutually restrictive and fitted. The third connecting ring 414 is fixedly connected to the mounting base 43 by bolts, which improves the connection stability and sealing between the third on / off valve 41 and the mounting base 43, and also facilitates the disassembly and subsequent maintenance of the third on / off valve 41 and the mounting base 43.

[0059] Reference Figure 1 , Figure 4 and Figure 7 The third connector 42 includes a third tube body 422 and a third external nut 423. The cavity of the third tube body 422 communicates with the first connection port 432. The third tube body 422 is directly and fixedly connected to the wall forming the first connection port 432, or the third tube body 422 is fixedly connected to the wall forming the first connection port 432 through an adapter pipe. The third tube body 422 and the third external nut 423 are sealed together and detachably connected. Both the third tube body 422 and the third external nut 423 are made of brass and have excellent corrosion resistance.

[0060] In an optional embodiment, the third shut-off valve assembly 40 further includes a third charging component, which is fixedly connected to the flow channel plate 10, or fixedly connected to the mounting base 43. The third charging component has a third charging channel and includes a third valve core, which is installed within the third charging channel. The third valve core is used to charge the working medium, such as refrigerant, into the thermal management system to ensure normal system operation and maintain stable system pressure. The third valve core is used to control the charging and shut-off of the medium, and can precisely adjust the charging amount, verify the charging effect and system sealing, and also facilitate system maintenance.

[0061] The third filling component includes a third filling valve cap and a third filling pipe section. The third filling valve cap and the third filling pipe section are detachably connected. The third filling valve is sealed to the third filling pipe section to ensure a tight seal. The third filling channel is located in the third filling pipe section, and the third filling valve cap is used to protect components such as the third valve core. The first connector 22, the second connector 32, and the third connector 42 are all located on the same side of the flow channel plate 10, which facilitates installation and results in a compact structure.

[0062] Reference Figure 1 , Figure 4 and Figure 7The thermal management device includes a plate heat exchanger 80 and a second filter 90, with the plate heat exchanger 80 fixedly connected to the flow channel plate 10. The second filter 90 has a second filter chamber 901, comprising a second filter housing 91 and a second filter element 92. The second filter element 92 is located in the second filter chamber 901 and is confined to the inner wall of the second filter chamber 901. The second filter housing 91 and the flow channel plate 10 are integrally formed. Compared to a system where the second filter 90 is connected to the flow channel plate 10 via piping, this design reduces piping connections and welding points, resulting in better overall sealing and structural pressure resistance.

[0063] The second filter 90 also includes a second cover 93, which is fixedly connected to the second filter housing 91. Specifically, a portion of the second cover 93 is located in the second filter chamber 901, and the second cover 93 is welded to the second filter housing 91. During assembly, the second filter element 92 is first installed in the second filter chamber 901, then the second cover 93 extends into the second filter chamber 901, and finally the second cover 93 is welded to the second filter housing 91 to achieve a fixed and sealed connection.

[0064] The plate heat exchanger 80 comprises multiple heat exchange plates stacked along its thickness direction, made of metals such as stainless steel and titanium. The surface of the heat exchange plates has a corrugated shape, with common corrugation shapes including herringbone, horizontal corrugations, and arc shapes. The corrugated design increases fluid turbulence, improves heat exchange efficiency, and also enhances the strength and rigidity of the plates. The plate heat exchanger 80 enables heat exchange between hot and cold fluids in the thermal management system, achieving functions such as heating, cooling, and condensation. The plate heat exchanger 80 has high heat transfer efficiency; under the same pressure loss, it transfers 6 to 7 times more heat than a shell-and-tube heat exchanger. It has a compact structure and small footprint; compared to a tube heat exchanger, its footprint is only one-third, facilitating the miniaturization of thermal management devices.

[0065] The first filter element 72 and the second filter element 92 can be filter screens, filter cartridges, etc. Filter screens are generally made of woven metal wire mesh (such as stainless steel wire mesh) or synthetic fibers. Filter cartridges are made of various materials, including paper, fiber, and sintered metal powder. Paper filter cartridges are relatively inexpensive and are often used in applications where filtration accuracy requirements are not extremely high; fiber filter cartridges have better filtration performance and can be repeatedly washed and reused; sintered metal powder filter cartridges have high strength and corrosion resistance, making them suitable for harsh working conditions.

[0066] The first filter 70 and the second filter 90 can filter out solid particles, impurities, metal shavings, etc. in the fluid of the thermal management system, preventing these impurities from entering key components such as the plate heat exchanger 80 and the compressor, avoiding damage to components due to wear and blockage, maintaining the cleanliness of the fluid in the thermal management system, ensuring the stability of the fluid's heat transfer performance and other physicochemical properties, preventing impurities from accumulating in the pipes, avoiding pipe blockage, ensuring the smooth flow of fluid in the system, maintaining the normal operation of the system, improving the reliability and stability of the thermal management system, and extending the service life of the thermal management device.

[0067] Reference Figure 1 , Figure 4 and Figure 6 The thermal management device includes a silencer 100, which is fixedly connected to a flow channel plate 10. The silencer 100 and the plate heat exchanger 80 are located on opposite sides of the flow channel plate 10. The silencer 100 has a silencing cavity 1001, which communicates with the flow channel 101. Both the inlet and outlet of the silencer 100 are directly connected to the flow channel plate 10. Specifically, the inlet and outlet of the silencer 100 are directly welded to the flow channel plate 10, reducing pipe connections and weld points. The overall thermal management device has good sealing performance and pressure resistance, and also reduces the size of the thermal management device.

[0068] During the operation of the thermal management unit, noise is generated by processes such as compressor operation and refrigerant flow. The silencer 100 reduces this noise. Furthermore, excessive noise is often accompanied by strong vibrations and pressure fluctuations. The silencer 100 weakens these vibrations and pressure fluctuations, thereby reducing impact and wear on pipes, valves, joints, and other equipment components, extending the service life of the thermal management unit. In addition, noise and vibration can affect the normal operation of sensors in the thermal management unit, leading to measurement errors and control instability. The silencer 100, by reducing noise and vibration, improves the working accuracy of the sensors and ensures stable system operation.
