Description

Technical Field

[0001] The invention relates to the technical field of vehicle engineering, and in particular to an automobile radiator. Background Art

[0002] As an important part of the engine cooling system, the main function of the car radiator is to effectively dissipate the heat generated during the operation of the engine to the environment to keep the temperature of the engine within the normal working range. Traditional car radiators generally adopt a tube-fin structure, in which the coolant flows through the pipe and the air exchanges heat through the fins. Although this design is effective, under certain high loads or extreme working conditions, the heat dissipation efficiency may be affected by factors such as flow resistance and uneven flow, resulting in unsatisfactory heat exchange effects.

[0003] At present, the performance of the radiator is mainly optimized through the following ways: 1. Increasing the heat exchange area: Improving the heat exchange efficiency by increasing the surface area of ​​the radiator. However, too much surface area will lead to an increase in the volume of the radiator, which will affect the space utilization of the car. 2. Increasing the fluid flow rate: By increasing the flow rate of the coolant and improving the degree of turbulence, the heat exchange effect is enhanced. However, too high a flow rate may result in greater energy consumption and noise. 3. Pipeline design and surface modification: By optimizing the roughness of the inner and outer surfaces of the pipeline, or changing the shape of the pipeline (such as a corrugated pipeline) to promote fluid turbulence, the heat exchange effect is enhanced. However, the optimization of pipeline design is often limited to the balance of factors such as flow rate and structural strength, and it is difficult to flexibly adjust under dynamic conditions.

[0004] Although the above methods have improved the performance of the radiator to a certain extent, the following limitations still exist: 1. Existing designs usually rely on fixed flow states and structural parameters, and lack the ability to dynamically adjust the fluid flow state (such as turbulence intensity). 2. Although existing heat exchange pipes and fin structures can induce turbulence by increasing surface roughness or changing the shape of the pipe, these changes are often fixed and cannot be dynamically adjusted according to different working conditions, resulting in heat exchange efficiency being lower than the optimal state under certain working conditions. 3. Many existing technologies rely on mechanical drives (such as gears, valves, etc.) to adjust fluid flow states or make other adjustments. These mechanical components are prone to wear or failure, which affects the reliability and life of the system.

[0005] Therefore, how to provide a technology that can accurately adjust the fluid flow state, improve heat exchange efficiency and have a long service life while ensuring the radiator structure is simple and efficient has become an urgent problem to be solved. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0032] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] like Figure 1 As shown, combined Figure 2-9The automobile radiator of the present invention comprises: a water inlet tank 1, a water inlet pipe 2, a water outlet tank 3, a water outlet pipe 4, a connecting tube 5, a flexible membrane 6 and a driving device 7. A plurality of parallel water inlet pipes 2 are arranged in an array along the length direction on one side of the water inlet tank 1 close to the water outlet tank 3. A plurality of parallel water outlet pipes 4 are arranged in an array along the length direction on one side of the water outlet tank 3 close to the water inlet tank 1. Each water inlet pipe 2 is connected to the water outlet pipe 4 through a connecting tube 5. A flexible membrane 6 is arranged in the axial direction of the connecting tube 5. The driving device 7 can drive the flexible membrane 6 to twist around the axial direction of the connecting tube 5.

[0035] In the above embodiments, the heat dissipation core is formed by connecting the water inlet pipe 2, the connecting tube 5 and the water outlet pipe 4. At this time, the heat dissipation core has a detachable characteristic. At the same time, by using this connection structure, the connection tube 5 can be partially disassembled and replaced. At the same time, in order to satisfy the disturbance of the coolant in the heat exchange pipe in the heat dissipation core, a corresponding disturbance structure or an adjustable structure can be provided in the connecting tube 5. Specifically, the technical scheme of the flexible membrane 6 and the driving device 7 is adopted in the above embodiments. Specifically, the flexible membrane 6 is arranged along the axial direction of the connecting tube 5. The two ends of the flexible membrane 6 along the axial direction can be driven by the driving device 7 to twist around the axis. During the twisting process, the channel structure formed by the flexible membrane 6 and the inner wall of the connecting tube 5 will change. When the flexible membrane 6 is not twisted, it is in a planar state. At this time, the flexible membrane 6 divides the space in the connecting tube 5 into two semi-cylindrical spaces. When the two ends of the flexible membrane 6 are twisted in opposite directions, the space in the connecting tube 5 where the flexible membrane 6 is located is divided into two spiral spaces. At this time, turbulence will occur when the water flows through the connecting tube 5, and as the degree of twisting increases, this turbulence will also increase.

[0036] By twisting the flexible membrane 6, the turbulence of the coolant in the pipe in the heat dissipation core can be changed, thereby improving the heat dissipation efficiency. The driving device 7 drives the flexible membrane 6 in a non-contact manner. It should be understood that the flexible membrane 6 is a well-known flexible material, which can be twisted to a certain extent and can be restored to its original state. The flexible membrane 6 can be made of elastic polymer material, elastic metal material, etc.

[0037] In some embodiments, a fixed bracket 8 is also included, and the water inlet box 1 and the water outlet box 3 are fixedly installed on both sides of the fixed bracket 8 respectively, and the water inlet pipe 2 and the water outlet pipe 4 are connected and arranged between the water inlet box 1 and the water outlet box 3 through a connecting tube 5.

[0038] In the above embodiments, the fixing bracket 8 is used to fix and support the water inlet tank 1 and the water outlet tank 3, and also supports other necessary components on the radiator.

[0039] In some embodiments, a first magnetic ring 9 is also included. Two annular grooves 51 are circumferentially arranged on the inner wall of the connecting tube 5. The two annular grooves 51 are arranged at intervals. The first magnetic ring 9 is coaxially embedded in the two annular grooves 51. The first magnetic ring 9 can rotate around the axis of the connecting tube 5 in the annular grooves 51. The two ends of the flexible membrane 6 along the axial direction of the connecting tube 5 are fixedly connected to the two first magnetic rings 9 respectively. The driving device 7 drives the two first magnetic rings 9 to rotate by magnetic force, so that the flexible membrane 6 twists.

[0040] In the above embodiments, in order to enable the flexible membrane 6 to be driven by an external contactless driving member inside the connecting tube 5, a first magnetic ring 9 is used to fix the two ends of the flexible membrane 6. The first magnetic ring 9 is divided into two magnetic poles along the radial direction. The annular groove 51 on the inner side of the connecting tube 5 is used to limit the first magnetic ring 9 in the axial direction and provide an installation space for the first magnetic ring 9 so that the first magnetic ring 9 does not affect the flow space inside the connecting tube 5. The driving device 7 guides the first magnetic ring 9 to rotate through magnetic force on the outer side of the connecting tube 5, thereby causing the flexible membrane 6 to twist easily.

[0041] It should be understood that the material of the connecting tube 5 will not affect the penetration and path of the magnetic flux lines. Preferably, the connecting tube 5 is made of non-magnetic materials such as polymer materials.

[0042] In some embodiments, a lubricating sheath 10 is further included. The surface of the first magnetic ring 9 is coated with a lubricating sheath 10 , and the lubricating sheath 10 is made of polytetrafluoroethylene.

[0043] In the above embodiments, in order to protect the first magnetic ring 9 as much as possible and avoid corrosion by the coolant and wear between the first magnetic ring 9 and the inner wall of the connecting tube 5, a lubricating sleeve 10 is provided on the surface of the first magnetic ring 9. Since polytetrafluoroethylene has good corrosion resistance and self-lubricating properties, it is best to use polytetrafluoroethylene material for the lubricating sleeve 10.

[0044] In some embodiments, balls 11 are further included. At least three balls 11 are rollingly arranged on one side of the two annular grooves 51 along the axis direction of the connecting tube 5 close to the flexible membrane 6 , and the first magnetic ring 9 is in rolling contact with the balls 11 .

[0045] In the above embodiments, considering that the dimension of the flexible membrane 6 along the axial direction tends to decrease during the twisting process, the stress of the first magnetic ring 9 on the side of the annular groove 51 close to the flexible membrane 6 along the axial direction will increase as the flexible membrane 6 twists. This may increase the friction between the first magnetic ring 9 and the annular groove 51, which is not conducive to further twisting movement. In order to overcome this problem, a corresponding space is provided on the inner side of the annular groove 51 close to the flexible membrane 6 along the axial direction, and a ball 11 is embedded in the space. The first magnetic ring 9 is supported by the ball 11. The rolling friction is much smaller than the sliding friction. Therefore, the problem of the first magnetic ring being difficult to rotate due to the increase in contact stress can be minimized.

[0046] In some embodiments, the driving device 7 includes a second magnetic ring 71 and a transmission member 72. The two second magnetic rings 71 are coaxially sleeved on the outside of the connecting tube 5. The second magnetic rings 71 can rotate relative to the connecting tube 5. The two second magnetic rings 71 are coplanar with the two first magnetic rings 9 respectively, and the two transmission members 72 respectively drive the two second magnetic rings 71 to rotate independently.

[0047] In order to cooperate with the above-mentioned first magnetic ring 9, the driving device 7 adopts a second magnetic ring 71 and a transmission member 72 to realize magnetic transmission. Specifically, the second magnetic ring 71 is provided with two levels in the radial direction. The second magnetic ring 71 is sleeved on the outside of the connecting tube 5 and slides together. The surface of the connecting tube 5 is provided with a corresponding limiting structure for limiting the position of the second magnetic ring 71 along the axial direction, so that the second magnetic ring 71 is in the same plane as the first magnetic ring 9. The transmission member 72 is used to drive the second magnetic ring 71 to rotate on the outside of the connecting tube 5. Since the first magnetic ring 9 and the second magnetic ring 71 are both radially two-stage annular magnets, when the two are coaxially and coplanarly nested, the rotation of the second magnetic ring 71 can drive the first magnetic ring 9 to rotate accordingly. Such a driving structure can realize contactless driving, thereby avoiding affecting the sealing of the connecting tube 5. At the same time, magnetic drive can bring a certain buffering effect, which can greatly reduce mechanical damage.

[0048] In some embodiments, the transmission member 72 includes a rack 721, a driven gear 722, a driving gear 723 and a driving motor 724. The driven gear 722 is coaxially fixed on the outside of the second magnetic ring 71. The driving motor 724 drives the driving gear 723 to rotate. The driving gear 723 and the driven gear 722 are both engaged with the rack 721. The rack 721 is slidably set on the fixed bracket 8, and the driving motor 724 is fixed to the surface of the fixed bracket 8.

[0049] The above embodiment provides a technical solution for a transmission member 72 with a simple structure and easy to implement. Specifically, the transmission member 72 has two sets, which are used to drive the two second magnetic rings 71 separately. A driven gear 722 is coaxially fixed to the outer side of the second magnetic ring 71. The rack 721 slides on the fixed bracket 8. The driving motor 724 drives the driving gear 723 to rotate. The driving gear 723 rotates to drive the rack 721 to slide. When the rack 721 slides, the corresponding driven gear 722 rotates and drives the second magnetic ring 71 to rotate, and finally the first magnetic ring 9 and the end of the flexible membrane 6 of the enemy camp are rotated, thereby achieving the purpose of twisting.

[0050] The above structural design can achieve the change of water flow direction at the connection between the water inlet pipe 2 and the water outlet pipe 4 by simple driving, thereby changing the turbulence of the coolant in the pipe. The change of turbulence will affect the heat exchange efficiency between the coolant and the pipe wall, thereby achieving the purpose of changing the heat exchange effect. Moreover, the structure connected by the connecting tube 5 can realize the separate replacement or maintenance of the connecting tube 5, and the overall structure is simple and easy to implement.

[0051] In some embodiments, heat dissipation fins 12 are also included, and a plurality of parallel heat dissipation fins 12 are arranged in an array on the surface of the water inlet pipe 2 and the surface of the water outlet pipe 4 .

[0052] In the above embodiments, the heat dissipation fins 12 are used to increase the surface areas of the water inlet pipe 2 and the water outlet pipe 4, thereby further improving the heat exchange efficiency.

[0053] In some embodiments, a water inlet 13 is formed on the surface of the water inlet box 1 , and a water outlet 31 is formed on the surface of the water outlet box 3 .

[0054] In some embodiments, a pressure relief valve 14 is further included, and at least one surface of the water inlet tank 1 and the water outlet tank 3 is connected and installed with the pressure relief valve 14 .

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
