The exhaust pipe increases the structural complexity and the number of parts of the manifold, which is not conducive to the integrated management of the manifold, and increases the cost of parts and the difficulty of the manufacturing process.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.
[0027] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.
[0028] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0029] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "outer", "end", "upper", "lower", "high", "lower", "inner", "middle", "side", "axial", "first direction", "second direction", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.
[0030] The "convergence plate" described in the embodiment of the present application refers to an intermediate component connected to the expansion kettle, which is used to divert and converge the coolant in the expansion kettle and discharge the bubbles in the coolant; the "expansion kettle" refers to a device used to store coolant and provide coolant cooling to the vehicle's battery circuit, electric drive circuit, warm air circuit and other cooling circuits. The expansion kettle is provided with a liquid replenishment port and a liquid return port. The expansion kettle introduces coolant into the cooling circuit through the liquid replenishment port, and then recovers the coolant in the cooling circuit through the liquid return port, so as to achieve the purpose of circulating cooling of the cooling circuit.
[0031] In order to meet the exhaust needs, the related technology adds an additional exhaust pipe to the manifold for exhaust, which increases the structural complexity and the number of parts of the manifold, is not conducive to the integrated management of the manifold, and increases the cost of parts and the difficulty of the manufacturing process.
[0032] In order to solve the technical problem that the exhaust method of the busbar in the related technology is relatively complicated, the busbar provided in the present application integrates a gas flow channel on the busbar channel, so that the bubbles in the busbar channel can be discharged out of the busbar through the gas flow channel, thereby eliminating the need to set an additional exhaust pipe on the busbar.
[0033] Below through Figures 1 to 3 The expansion kettle according to the embodiment of the present application is described in detail.
[0034] like Figures 1 to 3As shown, the present application provides a convergence plate 10 for a vehicle, the convergence plate 10 comprises: a plate body, a convergence channel 13 and a bifurcated flow channel 14, the top of the plate body is provided with an inlet 11 and an exhaust port 12; the convergence channel 13 is arranged inside the plate body and is connected with the inlet 11; the bifurcated flow channel 14 is arranged inside the plate body and is connected to the downstream of the convergence channel 13, the bifurcated flow channel 14 comprises a liquid flow channel 142 extending to the bottom of the plate body, and a gas flow channel 143 extending to the top of the plate body and connected with the exhaust port 12.
[0035] In this embodiment, the busbar 10 provided in the embodiment of the present application is connected to the gas flow channel 143 on the busbar channel 13, so that the bubbles in the busbar channel 13 can be discharged outside the busbar 10 through the gas flow channel 143, so that there is no need to set an additional exhaust pipe on the busbar 10. By deleting the exhaust pipe and placing the exhaust function of the busbar 10 in the busbar 10, the thermal management integrated module is designed as an internal degassing solution, which reduces the number of components while achieving the exhaust function and reduces the overall cost of components.
[0036] Specifically, since the density of bubbles is lighter than that of the coolant, the bubbles can float above the coolant. When the bubbles move to the gas flow channel 143 of the bifurcated flow channel 14, the gas flow channel 143 can provide a floating channel for the bubbles, so that the bubbles can be discharged to the outside of the busbar 10 through the gas flow channel 143 and the exhaust port 12. The busbar 10 provided in the present application only adds the corresponding bifurcated flow channel 14 to the original structure, which has little impact on the overall process of the busbar 10 and has almost no impact on the cost of the busbar 10.
[0037] In addition, the embodiment of the present application does not limit the specific distribution and specific structure of the bifurcated flow channel 14 because the main improvement of the present application is to provide a rising channel for the bubbles to be discharged through the bifurcated flow channel 14. As long as the bifurcated flow channel 14 can achieve this effect, it belongs to the protection scope of the embodiment of the present application. As for the specific distribution and specific structure of the bifurcated flow channel 14, it includes a variety of embodiments. Therefore, the embodiment of the present application does not limit this structure. Of course, in order to facilitate the understanding of the technical solution of the present application, the present application will elaborate on the specific distribution and specific structure of the bifurcated flow channel 14 through an embodiment described below.
[0038] The specific implementation of the bifurcated flow channel 14 is described below through the preferred embodiment of the present application.
[0039] like Figures 1 to 3 As shown, in some embodiments, the bifurcated flow channel 14 includes a horizontal flow channel 141, the upstream end of the horizontal flow channel 141 is connected to the converging channel 13, the liquid flow channel 142 is connected to the downstream end of the horizontal flow channel 141 and tilted downward, and the gas flow channel 143 is connected to the downstream end of the horizontal flow channel 141 and tilted upward.
[0040] In this embodiment, the horizontal flow channel 141 can buffer and decelerate the coolant, and the high-speed flowing coolant can be slowed down at the horizontal flow channel 141, which is beneficial for the coolant to achieve the purpose of gas-liquid separation and reduce the coolant from directly flowing into the liquid flow channel 142 due to bubbles driven by high-speed inertia.
[0041] Specifically, the busbar 10 is configured as a flat plate body. During use of the busbar 10, the plate body is placed vertically or laterally. Therefore, a busbar channel 13 with a height difference can be formed inside the plate body. The top of the plate body is located at the high end of the busbar channel 13, and the bottom of the plate body is located at the low end of the busbar channel 13. The horizontal flow channel 141 is located between the high end and the low end of the plate body, and the overall height of the horizontal flow channel 141 is consistent.
[0042] like Figures 1 to 3 As shown, in some embodiments, an island protrusion 15 is provided in the middle of the horizontal flow channel 141 , the upper area of the island protrusion 15 is set to correspond to the gas flow channel 143 , and the lower area of the island protrusion 15 is set to correspond to the liquid flow channel 142 .
[0043] In this embodiment, the island protrusion 15 can achieve the purpose of blocking and diverting the coolant. The coolant is blocked and the flow is slowed down at the island protrusion 15, thereby improving the separation effect of the coolant and the bubbles. At this time, the coolant flows to the liquid flow channel 142 below the island protrusion 15 due to gravity, and the bubbles flow to the gas flow channel 143 above the island protrusion 15.
[0044] Furthermore, the island protrusion 15 is configured as an arc-shaped protrusion, which can guide the coolant, thereby reducing the turbulence or eddy current of the coolant at the arc-shaped protrusion, and improving the circulation efficiency of the coolant at the arc-shaped protrusion.
[0045] like Figures 1 to 3 As shown, in some embodiments, the gas flow channel 143 is configured as a C-shaped flow channel, the bottom end of the C-shaped flow channel is connected to the downstream end of the horizontal flow channel 141 , and the top end of the C-shaped flow channel is connected to the exhaust port 12 .
[0046] In this embodiment, the C-shaped flow channel can provide a larger flow space for the gas, so that a part of the bubbles can be accumulated inside the C-shaped flow channel, thereby reducing the blockage of the bubbles inside the C-shaped flow channel.
[0047] Furthermore, the C-shaped flow channel can also slow down the circulation speed of the gas, thereby reducing the phenomenon that high-pressure and high-speed gas is directly discharged out of the manifold 10 .
[0048] like Figures 1 to 3As shown, in some embodiments, the bottom end of the C-shaped flow channel is configured as a flared structure, and the cross-sectional area of the C-shaped flow channel is configured to gradually decrease from the bottom end to the top end.
[0049] In this embodiment, the expansion structure can provide a larger inlet for the gas, allowing most bubbles to pass through the inlet of the C-shaped flow channel smoothly, reducing the blockage and turbulence of bubbles at the inlet of the C-shaped flow channel.
[0050] Furthermore, the cross-sectional area of the C-shaped flow channel is set to gradually decrease from the bottom to the top, so that the top of the C-shaped flow channel can be connected to the exhaust port 12 with a smaller diameter, and the manifold 10 can be connected to the smaller fluid infusion port 210 of the expansion kettle 200 through the smaller exhaust port 12, which is conducive to the miniaturized design of the manifold 10 and the expansion kettle 200.
[0051] like Figures 1 to 3 As shown, in some embodiments, the inlet 11 and the exhaust port 12 are disposed adjacent to each other, and the inlet 11 and the exhaust port 12 are separated by a partition, and the inlet 11 and the exhaust port 12 constitute a confluence port of the confluence plate 10 .
[0052] In this embodiment, the inlet 11 and the exhaust port 12 are arranged adjacent to each other, so that the inlet 11 and the exhaust port 12 can be integrated into a confluence port, which facilitates the connection between the confluence port of the confluence plate 10 and the liquid replenishment port 210 of the expansion kettle 200.
[0053] Furthermore, by forming the confluence port of the manifold 10 with the inlet 11 and the exhaust port 12, the number of the infusion ports 210 of the expansion kettle 200 can be reduced, thereby reducing the phenomenon of chaotic infusion management caused by too many infusion ports 210 and reducing the modification of the manifold 10 and the expansion kettle 200.
[0054] like Figures 1 to 3 As shown, in some embodiments, one end of the converging channel 13 is communicated with the inlet 11 , and the other end of the converging channel 13 is communicated with the bifurcated channel 14 after being bent in a direction away from the exhaust port 12 .
[0055] In this embodiment, the other end of the converging channel 13 is bent in a direction away from the exhaust port 12 and then connected to the bifurcated channel 14. The converging channel 13 can provide a larger flow space for the coolant, allowing a portion of the coolant to accumulate inside the converging channel 13, thereby reducing the blockage and turbulence of the branched coolant inside the converging channel 13.
[0056] Specifically, the confluence channel 13 can be configured as a C-shaped structure, a semicircular structure, or a half-mouth structure, and these embodiments all fall within the protection scope of the confluence channel 13 .
[0057] like Figures 1 to 3As shown, in some embodiments, the plate body, the converging channel 13 and the bifurcated flow channel 14 are configured as an integrally formed structure, and the converging channel 13 and the bifurcated flow channel 14 are integrated inside the cavity of the plate body.
[0058] In this embodiment, the busbar 10 provided in the present application only adds corresponding bifurcated flow channels 14 to the original structure, which has little impact on the overall process of the busbar 10 and almost no impact on the cost of the busbar 10.
[0059] The converging channel 13 and the bifurcated channel 14 are arranged on the plate body by machining or casting, which has almost no influence on the material and external structure of the plate body, thereby reducing the material cost and manufacturing cost of the plate body.
[0060] The second aspect of the present application provides a busbar assembly 100 , comprising a cover plate 20 and the busbar 10 according to the first aspect of the present application. The cover plate 20 is covered on the busbar 10 and is provided with a cover port 21 connected to a busbar port of the busbar 10 .
[0061] In this embodiment, the busbar assembly 100 is formed by combining the cover plate 20 and the busbar 10, so that the busbar channel 13 and the branch channel 14 can be processed on the surface of the busbar 10. The busbar channel 13 and the branch channel 14 are processed by machining or casting, which reduces the processing difficulty of the busbar channel 13 and the branch channel 14 and reduces the processing cost of the busbar assembly 100.
[0062] The manifold assembly 100 further includes a water pump 30 , which is disposed at the liquid flow channel 142 of the bifurcated flow channel 14 and is used to pump coolant at the liquid flow channel 142 to cooling circuits such as a battery circuit, an electric drive circuit, and a heater circuit of the vehicle.
[0063] In addition, the busbar assembly 100 proposed in the embodiment of the present application has all the technical effects of the busbar 10, which will not be elaborated in detail here.
[0064] A third aspect of the present application provides a vehicle, comprising an expansion kettle 200 and the manifold assembly 100 according to the second aspect of the present application, wherein the expansion kettle 200 is provided with a fluid replenishing port 210 communicating with the cover port 21 of the manifold assembly 100 .
[0065] In this embodiment, the manifold 10 is connected to the expansion kettle 200 to divide and merge the coolant in the expansion kettle 200, and then provide coolant cooling to the vehicle's battery circuit, electric drive circuit, heating circuit and other cooling circuits.
[0066] The vehicle proposed in the embodiment of the present application has all the technical effects of the busbar assembly 100 and the busbar 10 , which will not be elaborated in detail here.
[0067] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
[0068] In addition, the embodiments of the present application only describe the structures of the busbar assembly 100 and the busbar 10 related to the improvements of the present application, and do not mean that the busbar assembly 100 and the busbar 10 of the present application do not have other structures. For example, the busbar 10 also includes structures such as a water supply port and a water return port connected to an external cooling member. These structures all belong to the protection scope of the busbar assembly 100 and the busbar 10 of the embodiments of the present application. The other structures of the busbar assembly 100 and the busbar 10 will not be described one by one here.
[0069] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
