TECHNICAL FIELD

[0001] The utility model belongs to water cooling joint technical field, especially relate to a variable cross section channel's water cooling joint. BACKGROUND

[0002] With the continuous progress of electric vehicle technology, the heat dissipation requirements of key components such as batteries, motors and electronic control systems are becoming higher and higher, and water cooling joints are key components of cooling systems in the field of new energy vehicles. Effective thermal management is the basis for ensuring that these components can operate within a safe operating temperature range and maintain high performance and long life.

[0003] However, the power battery and drive motor of new energy vehicles will generate different levels of heat under different working conditions (such as high-speed driving, rapid charging, low-speed driving, etc.). The water cooling joint with fixed cross section cannot adjust the flow rate and flow of the coolant according to these changes, which may result in insufficient cooling under high heat load or energy waste under low heat load.

[0004] Therefore, the above situation needs to be solved. INVENTION CONTENTS

[0005] The utility model aims at overcoming the above-mentioned defects, and provides a variable cross section channel's water cooling joint, which can improve the adaptability and flexibility of the entire cooling system through the variable cross section water cooling joint.

[0006] Technical scheme: a variable cross section channel's water cooling joint, comprising an outer shell, a first joint, a second joint, an inner membrane cavity, the two sides of the outer shell are respectively screwed with the first joint and the second joint, and the inner membrane cavity is formed in the outer shell; characterized in that it further comprises a variable cross section assembly, the variable cross section assembly is arranged in the inner membrane cavity; the variable cross section assembly comprises a group of blades, a group of connecting assemblies and a support ring, the connecting assemblies are arranged on the inner wall of the support ring in a slanting manner; the blades are arranged in a radial wrapping shape and are rotationally connected to the connecting assemblies. By using the variable cross section assembly, the water cooling joint can adjust the size of the cross section area of the internal passage according to actual needs, and can automatically adjust according to the changes in flow or pressure, so that the best performance can be maintained under different working conditions.

[0007] Further, the connecting assembly comprises a connecting support and a connecting shaft, the connecting shaft is arranged in the connecting support; one end of the blade is provided with a ring-shaped connecting head which is connected to the connecting shaft. By arranging the ring-shaped connecting head at one end of the blade and penetrating the connecting shaft, the blade can rotate around the connecting shaft, so that the blade can automatically adjust the angle according to the pressure and flow of the fluid, thereby realizing accurate control of the cross-sectional area of the flow channel and optimizing the cooling effect.

[0008] Further, the blades abut each other, and the side edges and bottom edges are arranged in arc shapes. The arc-shaped design of the application can more effectively guide water flow, reduce turbulence and flow resistance, and compared with straight edge design, the arc-shaped edge helps to achieve a smoother fluid transition, thereby improving cooling efficiency; and the arc shape has good wrapping and sealing properties, so that the cooling liquid can not leak when flowing.

[0009] Further, a plurality of grooves are arranged on the inner wall of the shell, and elastic elements are arranged in the grooves, and one end of the elastic element is connected to the blade. The elastic element arranged in the application can automatically adjust the angle of the blade according to the pressure of the fluid. This mechanism makes the water cooling connector have better self-adaptive ability, and can maintain the best cooling effect under different working conditions; and the elastic element can absorb and buffer the influence of external vibration or internal pressure fluctuation on the blade, reduce the damage caused by mechanical vibration or instantaneous high pressure to the system, and improve the stability and reliability of the equipment.

[0010] Further, the grooves and elastic elements are arranged in at least 4 groups and are uniformly arranged on the inner wall of the shell. The arrangement of at least 4 groups of elastic elements in the application plays an auxiliary sealing role to prevent leakage of the cooling liquid. In particular, during the dynamic adjustment process, the elastic element ensures the close contact between the blades, thereby enhancing the sealing performance of the overall device.

[0011] Further, the support ring is arranged between the first connector and the shell, and a sealing ring is arranged between the support ring and the first connector. The support ring in the application is located between the first connector and the shell, which provides additional mechanical support for the entire assembly, ensuring that the internal components can be stably maintained in their designed positions. This helps to prevent structural deviation or damage caused by external vibration or internal pressure changes; the sealing ring arranged between the support ring and the first connector can effectively prevent leakage of the cooling liquid, thereby improving the overall sealing performance and reliability of the system.

[0012] Further, the width of the support ring is equal to the width of the sealing ring. The consistent width design of the application enables the sealing ring to be uniformly distributed on the support ring when under pressure, thereby avoiding local stress concentration problems. This can reduce the wear of the sealing ring, prolong its service life, and maintain long-term stable sealing effect.

[0013] The above technical solutions can have the following beneficial effects:

[0014] 1. The application relates to a water cooling connector with a variable cross-section channel. For the water cooling connector with a variable cross-section design, the cross-sectional area can be increased to adapt to a larger flow rate, so that the flow rate can be controlled to be not too high, and pressure loss, noise and wear on the pipe wall can be reduced.

[0015] 2. The application relates to a variable cross-section channel water-cooled joint, wherein elastic elements are arranged to automatically adjust the angle of the blades according to the pressure of the fluid, so that the water-cooled joint has better self-adaptability and can maintain the best cooling effect under different working conditions; and the elastic elements can absorb and buffer the influence of external vibration or internal pressure fluctuation on the blades, reduce the damage caused by mechanical vibration or instantaneous high pressure to the system, and improve the stability and reliability of the equipment.

[0016] 3. The application relates to a variable cross-section channel water-cooled joint, wherein the blades are designed in an arc shape, so that the water flow can be more effectively guided, the turbulent flow and flow resistance are reduced, the arc-shaped edge helps to realize more smooth fluid transition compared with the straight edge design, so that the cooling efficiency is improved; and the arc shape has good wrapping and sealing properties, so that the cooling liquid can not leak when flowing.

[0017] 4. The application relates to a variable cross-section channel water-cooled joint, wherein a plurality of elastic elements are arranged to play an auxiliary sealing role and prevent the cooling liquid from leaking. In particular, during the dynamic adjustment process, the elastic elements ensure the close contact between the blades and the blades, and the sealing performance of the overall device is enhanced.

[0030] Further, the blades 401 abut each other, and the side edges and the bottom edges are arranged in an arc shape.

[0031] Further, please refer to Figure 6 As shown, a group of grooves 8 are arranged on the inner wall of the outer shell 1, elastic elements 7 are arranged in the grooves 8, and one end of the elastic element 7 is connected to the blade 401.

[0036] Embodiment 2

[0037] The embodiment further introduces a variable cross-section channel water cooling joint. Based on the above embodiment, the working principle of the present application is further introduced:

[0038] The variable cross-section component 4 in the present application can automatically adjust the channel cross-sectional area according to the pressure change of the fluid without external driving, thereby effectively controlling the flow path and speed of the cooling liquid.

[0039] Further, the blades 401 are arranged in a radial wrapping manner, and the long edges and bottom edges thereof are designed as arc shapes. Such design not only helps to guide the water flow to pass more smoothly, reduces turbulence and flow resistance, but also allows more flexible control of the opening and closing degree of the flow passage to accurately adjust the direction and speed of the water flow. The blades 401 are rotationally connected through the connecting components 402, so that the blades 401 can freely rotate as needed.

[0040] Further, a series of grooves 8 are arranged on the inner wall of the outer shell 1, and an elastic element 7 is installed in each groove 8. One end of the elastic element 7 is connected with the blade 401. When the cooling liquid flows through, the elastic element 7 will correspondingly stretch and contract according to the change of the fluid pressure, thereby automatically adjusting the angle of the blade 401. In the case of high pressure, the elastic element 7 is compressed, and the blade 401 rotates to increase the channel cross-sectional area; while in the case of low pressure, the elastic element 7 returns to its original state, pushing the blade 401 back to the initial position. The whole process does not require any external driving force, and the automatic adjustment of the angle of the blade 401 is completely realized by relying on the pressure change of the fluid itself.

[0041] Further, the elastic element 7 can assist the sealing action between the blade 401 and the blade 401. When one of the blades 401 is driven, the interaction force between the blades 401 can drive all the blades 401 to tightly abut.

[0042] Further, in the present embodiment, the elastic element 7 is selected as a spring.

[0043] Further, the support ring 403 is located between the first joint 2 and the outer shell 1, and a sealing ring 6 is arranged between the support ring 403 and the first joint 2, which ensures the stability and sealing property of the structure. The width of the support ring 403 is equal to the width of the sealing ring 6, which helps to maintain the stability of the overall device and ensure the sealing effect.

[0044] Further, therefore, the design of the variable cross-section component 4 realizes the function of automatically adjusting the channel cross-sectional area according to the pressure change of the cooling liquid without the need of external power source. It can dynamically respond to different working condition requirements, optimize the cooling efficiency, and ensure that the cooling system can maintain the best operating state under various operating environments. This feature makes the water cooling joint have high adaptability and reliability, and is suitable for various application scenarios.

[0045] In another embodiment, a small driving device and an intelligent sensing device can be arranged inside the support ring 403, and the opening and closing of the blades 401 are automatically driven and adjusted by sensing the external temperature, so as to realize a water cooling joint with a variable cross-section channel.
