Description

Technical Field

[0001] This utility model relates to the field of cooling technology for power modules, specifically to a cooling water channel. Background Technology

[0002] In the field of electric vehicles and new energy vehicles, charging and distribution systems or on-board chargers are key energy conversion and distribution components, and their performance and reliability directly affect the vehicle's range and overall operating efficiency. To improve the heat dissipation performance of these components and ensure their stable operation under long-term, high-power conditions, integrating a high-efficiency water-cooling system into the main casing of the charging and distribution system or on-board charger has become a mainstream design trend in the industry.

[0003] Currently, the main housing of charging and distribution systems or on-board chargers is generally manufactured using a combination of die casting and friction stir welding. Die casting is widely used because it can efficiently and precisely produce metal parts with complex shapes, while friction stir welding, with its high strength, low heat input, and low deformation characteristics, is particularly suitable for joining lightweight, high-strength materials such as aluminum alloys, ensuring the structural strength and sealing of the main housing. The combination of these two processes makes it possible to directly form complex water channel structures within the main housing, thereby greatly improving heat dissipation efficiency.

[0004] However, with the increasing demands for integration, lightweight design, and heat dissipation performance in charging and distribution systems or on-board chargers, existing water channel designs face several challenges. Specifically, the large volume occupied by the water channels on the main casing results in extremely limited space around them. This space constraint increases the difficulty of layouting related functional modules (such as electrical components, sensors, and control units).

[0005] Therefore, it is necessary to develop a new cooling water channel. Utility Model Content

[0006] The purpose of this invention is to provide a cooling water channel that is small in size and has good heat dissipation.

[0007] The present invention provides a cooling water channel, which includes a main water channel and a water channel cover plate, which are combined to form a closed water channel.

[0008] The main waterway includes a waterway body, which has a first surface and a second surface that are disposed opposite to each other.

[0009] The first surface has a first sidewall extending in a first direction around its perimeter to form a water channel, and the water channel is sealed to a water channel cover to form a water channel.

[0010] The second surface has a second sidewall extending in a second direction opposite to the first direction around its perimeter, forming an installation space;

[0011] One end of the second surface is provided with an inlet that communicates with the water channel, and the other end of the second surface is provided with an outlet that communicates with the water channel.

[0012] Optionally, a plurality of power transmission component vias are provided at intervals on the outer periphery of the second sidewall for copper busbars on the power board to pass through.

[0013] Optionally, the inner wall of the water channel cover is provided with multiple heat dissipation columns to increase the contact area with the coolant and improve heat dissipation efficiency.

[0014] Optionally, the inlet and outlet are respectively located at opposite ends of the second surface for the inflow and outflow of coolant.

[0015] Optionally, the installation space is divided into a first installation space, a second installation space, and a third installation space, which are independent of each other, for installing different parts or components.

[0016] Optionally, the second surface has a water inlet sealing surface around the liquid inlet to ensure a tight seal when coolant flows in.

[0017] Optionally, the second surface is provided with a water outlet sealing surface around the perimeter near the liquid outlet to ensure the sealing when the coolant flows out.

[0018] Optionally, a plurality of first mounting holes are provided at intervals on the outer periphery of the second sidewall for fixing and connecting other parts or components.

[0019] Optionally, a plurality of second mounting holes and a plurality of third mounting holes are provided at intervals on the outer periphery of the first sidewall for fixing and connecting other parts or components.

[0020] Optionally, a plurality of third mounting holes are provided at intervals on the outer periphery of the first sidewall for fixing and connecting other parts or components.

[0021] The beneficial effects of this utility model are:

[0022] (1) Compact structural design:

[0023] The main waterway comprises the waterway body, with sidewalls extending in opposite directions on its first and second sides. This design not only saves space but also creates different structural spaces to accommodate various installation requirements. This compact layout allows the entire system to operate efficiently within a limited volume.

[0024] (2) Efficient coolant flow path:

[0025] The inlet and outlet are located at opposite ends of the second side of the water channel body, ensuring that the coolant can flow smoothly into and out of the water channel. This design optimizes the coolant flow path and improves cooling efficiency.

[0026] (3) Increased heat dissipation area:

[0027] The inner wall of the water channel cover is equipped with multiple heat dissipation columns, which greatly increase the contact area with the coolant. By increasing the heat dissipation area, the coolant can more effectively absorb and remove heat, thereby improving the heat dissipation effect.

[0028] (4) Improved sealing performance:

[0029] The inlet and outlet are respectively provided with inlet sealing surfaces and outlet sealing surfaces. These sealing surfaces ensure the sealing of the coolant when it flows in and out, prevent coolant leakage, and thus ensure the stability and efficiency of the heat dissipation system.

[0030] (5) Flexible installation and connection design:

[0031] Multiple mounting holes (including power transmission component through holes, first mounting holes, second mounting holes, and third mounting holes) are provided on the outer periphery of the second sidewall and the first sidewall, respectively. These mounting holes not only facilitate the fixed connection of other components or assemblies, but also provide a variety of installation options, enabling the entire system to be flexibly configured as needed.

[0032] In summary, this main water channel design achieves excellent heat dissipation performance despite its small size through a compact structural layout, optimized coolant flow path, increased heat dissipation area, improved sealing, and flexible installation and connection design. These design optimizations work together to improve the overall cooling water channel, resulting in a smaller size and significantly enhanced heat dissipation performance.

[0039] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0040] like Figure 1 and Figure 5 As shown in the embodiment of this application, a cooling water channel includes a main water channel 1 and a water channel cover plate 2, which are welded together by processes such as friction stir welding, brazing or laser welding to form a closed water channel 3.

[0041] like Figure 2 and Figure 3 As shown in the embodiment of this application, the main waterway 1 includes a waterway body, which has a first surface and a second surface disposed opposite to each other. The periphery of the first surface has a first sidewall extending in a first direction, forming a waterway groove 171. The waterway groove 171 is sealed to the waterway cover plate 2 to form a waterway 3. The periphery of the second surface has a second sidewall extending in a second direction opposite to the first direction, forming an installation space. One end of the second surface has an inlet 101 communicating with the waterway groove 171, and the other end of the second surface has an outlet 102 communicating with the waterway groove 171.

[0042] like Figure 2 and Figure 3 As shown in the embodiment of this application, the first sidewall extends in a first direction to form a water channel, and the second sidewall extends in the opposite direction to form an installation space. By using the bidirectionally extending sidewalls, the water channel 3 and the installation space are separated and integrated onto the same main body, avoiding the volume redundancy caused by multi-layer stacking in traditional designs. Furthermore, the installation space and the water channel 3 share the same water channel body, reducing additional support structures and significantly compressing the overall size.

[0043] like Figure 3As shown, in one possible embodiment, a plurality of power transmission component through-holes 161 are spaced apart on the outer periphery of the second sidewall. These are for copper busbars on the power board to pass through. High-heat components such as copper busbars can be directly embedded into the mounting space through the power transmission component through-holes 161, with their heat-generating parts in close contact with the main water channel body, and heat is rapidly conducted to the coolant through the water channel body.

[0044] like Figure 2 As shown, in one possible embodiment, the inlet 101 and outlet 102 are respectively located at opposite ends of the second surface for the inflow and outflow of coolant. The inlet 101 and outlet 102 are positioned at opposite ends of the second surface, forming a diagonal flow channel. Coolant flows in from one end and out from the other, forming a long-distance unidirectional flow path, avoiding localized stagnant areas, and ensuring that the coolant fully covers the entire water channel 171.

[0045] like Figure 2 As shown, in one possible embodiment, the installation space is divided into a first installation space 131, a second installation space 132, and a third installation space 133, which are independent of each other. Modular partitioning optimizes component layout and avoids wasted space. For example, components with different functions (such as power devices and control units) can be installed independently, reducing redundant gaps. The partitioning design also avoids mechanical interference between components, reduces dependence on installation accuracy, and further simplifies the structure.

[0046] like Figure 4 As shown, in one possible embodiment, the inner wall of the water channel cover 2 is provided with multiple heat dissipation columns 201. The heat dissipation columns 201 increase the contact area with the coolant, thereby improving the heat transfer efficiency. At the same time, the heat dissipation columns 201 can disrupt the laminar flow state of the coolant, enhance turbulence, and accelerate the transfer of heat from the water channel wall to the liquid.

[0047] like Figure 2 and Figure 3 As shown, in one possible embodiment, a plurality of first mounting holes 121 are provided at intervals on the outer periphery of the second sidewall for fixing and connecting other components or assemblies. A plurality of second mounting holes 141 and a plurality of third mounting holes 151 are provided at intervals on the outer periphery of the first sidewall for fixing and connecting other components or assemblies.

[0048] like Figure 2 As shown, in one possible embodiment, the second surface has an inlet sealing surface 111 around the perimeter near the inlet 101 to ensure a tight seal when coolant flows in. The second surface also has an outlet sealing surface 112 around the perimeter near the outlet 102 to ensure a tight seal when coolant flows out. The design of the inlet sealing surface 111 and the outlet sealing surface 112 ensures stable flow channel pressure and prevents leakage that could reduce heat dissipation efficiency.

[0049] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
