Description

Technical Field

[0001] The utility model relates to the technical field of automobile thermal management systems, in particular to a flow channel plate used for a thermal management integrated module. Background Art

[0002] The flow plate in the automotive thermal management integrated module is a very important component in the automotive thermal management system. It plays a key role in the automotive engine cooling system, effectively regulating the temperature of the engine, ensuring the normal operation of the engine, and improving the fuel efficiency of the vehicle. The flow plate is designed to achieve uniform distribution and flow of fluid in the entire cooling system. There are usually multiple channels inside the flow plate to guide the coolant to flow in the entire cooling system.

[0003] In the prior art, the thermal management integrated module is affected by factors such as the layout of the cabin pipeline, the direction of the mold ejection, and the multi-layer welded flow channel plate, resulting in the coolant inlet and the coolant outlet on the flow channel plate being usually arranged at right angles. Therefore, in order to connect the coolant inlet and the coolant outlet, a flow channel with a right-angle structure is arranged between the coolant inlet and the coolant outlet. However, the right-angle flow channel in the flow channel plate will greatly increase the flow resistance of the coolant, especially in the right-angle flow channel structure where the coolant outlet is arranged above the coolant inlet, resulting in the water pump needing to do more work to overcome the resistance caused thereby, causing an increase in the power of the water pump, which in turn leads to an increase in the power consumption of the whole vehicle and an increase in the cost of the water pump; at the same time, the coolant flowing through the corners of the right-angle flow channel will also experience turbulence and backflow, resulting in increased vibration of the flow channel plate, which is manifested as increased noise, seriously affecting the NVH performance of the integrated module.

[0004] Therefore, it is necessary to improve the right-angle flow channel structure in the existing flow channel plate to solve the defects of the right-angle flow channel structure. Utility Model Content

[0005] In view of this, the utility model provides a flow channel plate for a thermal management integrated module, which reduces the flow resistance in the right-angle flow channel by setting a guide section at the corner of the right-angle flow channel, while improving the stability of the coolant passing through the corner of the right-angle flow channel, reducing the frontal impact of the coolant on the flow channel plate, and optimizing the NVH performance of the integrated module during operation.

[0007] Furthermore, the guide section is a spiral groove structure and is arranged between the liquid outlet of the inlet flow channel and the liquid inlet of the outlet flow channel, and the connecting end of the guide section and the inlet flow channel is lower than the connecting end of the guide section and the outlet flow channel in the vertical direction.

[0008] Furthermore, the connecting end between the guide section and the inlet flow channel and the connecting end between the guide section and the outlet flow channel are both arranged with smooth transition.

[0009] Furthermore, the liquid inlet of the inlet flow channel is connected to the liquid outlet of the water pump structure, and the flow channel cross section from the liquid inlet of the inlet flow channel to the liquid outlet of the inlet flow channel is arranged with a gradually increasing cross-sectional area.

[0017] As shown in the figure, the utility model provides a flow channel plate for a thermal management integrated module, including a flow channel plate shell, on which a coolant inlet 2 and a coolant outlet 1 distributed at right angles are arranged, and a right-angle flow channel for connecting the coolant inlet 2 and the coolant outlet 1 is opened in the flow channel plate shell, and the right-angle flow channel is provided with an inlet flow channel 3, a guide flow channel 4 and an outlet flow channel 5 in sequence along the coolant flow direction, and the guide flow channel 4 is arranged at the corner of the right-angle flow channel and is respectively connected to the inlet flow channel 3 and the outlet flow channel 5, and a guide section 6 for guiding the flow of the coolant is arranged in the guide flow channel 4; the corners of the right-angle flow channels in the prior art are mostly transitioned at right angles, but the coolant outlet In the right-angle flow channel structure arranged above the coolant inlet, the coolant still directly impacts the flow channel wall when passing through the corner. When the coolant flow pressure is insufficient, the flow resistance is large and backflow is easily formed. In the present technical solution, a guide section 6 for guiding the flow is provided in the guide flow channel at the corner, and the coolant flowing through is guided by the guide section 6 to avoid the coolant directly impacting the flow channel wall, so as to promote the coolant to pass through the right-angle flow channel in a stable state of laminar flow as much as possible, so as to reduce the flow resistance of the coolant when flowing through the corner of the right-angle structure, thereby reducing the water pump power and the operating cost of the thermal management integrated module; wherein the guide section 6 can be a circular arc transition or a spiral transition structure, which will not be repeated here.

[0018] In this embodiment, the guide section 6 is a spiral groove structure and is arranged between the liquid outlet of the inlet flow channel 3 and the liquid inlet of the outlet flow channel 5. The connecting end of the guide section 6 and the inlet flow channel 3 is lower than the connecting end of the guide section 6 and the outlet flow channel 5 in the vertical direction; the connecting end of the guide section 6 and the inlet flow channel 3 and the connecting end of the guide section 6 and the outlet flow channel 5 are both smoothly transitioned; combined with Figure 1 and Figure 2As shown, since the coolant outlet is arranged above the coolant inlet in the present solution, the coolant flowing through the guide channel 4 needs to flow upward under the action of the water pump after flowing into the guide channel. In order to reduce the power of the water pump, the guide section 6 is selected to be a spiral groove structure, which will rotate and rise the coolant flowing into the guide channel 4 along the spiral groove structure, so that the coolant flowing out of the guide has an initial upward flow velocity, and finally flows to the coolant outlet 1 with the action of the water pump; at the same time, the connecting end of the guide section 6 and the inlet channel 3 and the connecting end of the guide section 6 and the outlet channel 5 are designed to be a smooth transition, so that the coolant passes through in a stable state of laminar flow, thereby reducing the vibration of the flow channel plate; this structural design can reduce the flow resistance of the flow channel without changing the position angle of the inlet and outlet, improve the stability of the coolant when passing through the right-angle bend of the flow channel, reduce the frontal impact of the coolant on the flow channel wall, and optimize the NVH performance of the integrated module during operation.

[0019] In this embodiment, the liquid inlet of the inlet flow channel 3 is connected to the liquid outlet of the water pump structure, and the flow channel cross section from the liquid inlet of the inlet flow channel 3 to the liquid outlet of the inlet flow channel 3 is arranged with a gradually increasing cross-sectional area; Figure 1 As shown, by setting the flow cross section from the inlet of the inlet flow channel 3 to the flow cross section of the outlet of the inlet flow channel 3 to be gradually increased in cross-sectional area, the flow rate of the coolant flowing from the outlet of the water pump structure into the inlet flow channel 3 is gradually slowed down, avoiding excessive impact force caused by the flow rate contacting the flow channel wall, thereby affecting the flow resistance in the flow channel and causing reflux of the coolant.

[0020] In this embodiment, the liquid outlet of the outlet flow channel 5 is connected to the liquid inlet of the pipeline arranged on the thermal management integrated module, and the flow channel cross section from the liquid inlet of the outlet flow channel 5 to the flow channel cross section of the outlet flow channel 5 is gradually reduced in cross-sectional area; combined with Figure 1 As shown, the cross-sectional area of ​​the flow channel from the inlet of the outlet flow channel 5 to the outlet of the outlet flow channel 5 is gradually reduced. Since the guide flow channel 4 and the inlet flow channel 3 are full of coolant, and the coolant continues to flow into the right-angle flow channel, the flow pressure of the coolant in the outlet flow channel 5 flowing to the coolant outlet 1 will gradually increase, which is more conducive to the coolant flowing out of the right-angle flow channel.

[0021] In this embodiment, the flow channel plate housing includes an upper housing 7 and a lower housing 8, the coolant outlet 1 is arranged on the upper housing 7, the coolant inlet 2 is arranged on the lower housing 8, and the upper housing 7 and the lower housing 8 are welded to each other to form a right-angle flow channel structure in the internal cavity; Figure 1As shown, the upper shell 7 and the lower shell 8 are usually made of aluminum alloy or plastic material, which has good thermal conductivity and corrosion resistance; while in the present embodiment, the upper shell 7 and the lower shell 8 are welded to each other to form multiple flow channels in the internal cavity, including but not limited to right-angle flow channels to guide the coolant to flow in the entire cooling system.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
