Description

Technical Field

[0001] This utility model relates to the field of radiator return water pipe technology, and in particular to a lightweight, high-strength radiator return water pipe. Background Technology

[0002] The radiator is the core component of the heat exchange system. It transfers heat from high-temperature areas (such as engines and electronic devices) to the external environment through the circulation of fluids (such as coolant). The return pipe is the pipe that connects the radiator outlet and the heat source inlet in the radiator system. Its function is to guide the coolant back to the heat source after heat dissipation, forming a circulation loop. The radiator and the return pipe together constitute a closed circulation system to ensure the continuous removal of heat and the stability of the system temperature.

[0003] Chinese patent discloses an automotive return water pipe (authorization announcement number CN203231005U). This patented technology includes a main pipe and a secondary pipe. The lower end of the secondary pipe is integrally welded to the pipe wall of the main pipe, and both the main pipe and the secondary pipe have pressure gauge interfaces on their middle pipe walls. The other end of the main pipe is fitted with a weld-free flange, and the middle of the main pipe has a fixing bracket for installation. The upper ends of both the main pipe and the secondary pipe have mounting parts for cooperating with dust caps.

[0004] This patented technology offers convenient pressure testing and low-cost return water pipes, but it still has shortcomings in use. The return water pipe connects the radiator outlet and the water pump inlet in the cooling system. After the coolant is cooled by the radiator, it is pumped back to the engine for circulation. In addition, it may also be connected to the expansion tank to balance pressure and replenish coolant. Existing radiator return water pipes mostly use single-layer metal pipes, which have problems such as heavy weight, easy corrosion, and insufficient pressure resistance. They are also heavy and prone to breakage at bends. Therefore, those skilled in the art have provided a lightweight, high-strength radiator return water pipe to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a lightweight, high-strength radiator return water pipe, comprising,

[0008] The return water pipe structure includes a stainless steel corrugated pipe located inside the return water pipe structure, a carbon fiber braided reinforcement layer located in the middle layer of the return water pipe structure, an aluminum alloy protective shell located outside the carbon fiber braided reinforcement layer, and conical butt joints located at both ends of the return water pipe structure.

[0009] as well as;

[0010] The mounting structure includes a mounting tube, a plug located at one end of the mounting tube and slidably inserted into the connector, a rotating seat fixed on the outer wall of the plug in a ring array, a rotating shaft rotatably mounted inside the rotating seat, a mounting block located at one end of the rotating shaft, a retaining bead rotatably mounted inside the lower end of the mounting block, a retaining seat fixed on the outer wall of the connector in a ring array, and a torsion spring sleeved on the outside of the rotating shaft and connected at both ends to the mounting block and the rotating seat respectively.

[0011] Furthermore, the inner wall of the connector is provided with a flow guide ring corresponding to the plug, and one end of the flow guide ring is provided with a sealing gasket that fits into the opening of the connector in a ring-shaped distribution.

[0012] Specifically, the guide ring mates with the opening of the connector, allowing cooling water to enter the plug smoothly and directly. The sealing gasket improves the sealing performance of the contact surface between the connector and the guide ring.

[0013] Furthermore, a sealing ring that fits against the outer wall of the plug is embedded in the opening of the connector, the retaining bead is engaged inside the retaining seat, and the upper end of the retaining seat is arc-shaped;

[0014] Specifically, the sealing ring improves the sealing performance between the outer wall of the plug and the opening of the connector, and the adjustment of the rotating installation of the retaining ball reduces the frictional resistance when docking with the socket.

[0015] Furthermore, a connecting strip is provided at one end of the mounting block, a threaded sleeve is threadedly installed on the outer wall of the mounting tube, a limiting ring located on one side of the threaded sleeve is sleeved on the outer wall of the mounting tube, and a ball bearing that rolls and fits against the lower end of the connecting strip is rotatably installed on the outer wall of the threaded sleeve.

[0016] Specifically, the threaded sleeve is located at the lower end of the connecting bar to limit the connecting bar and prevent it from rotating. At the same time, the limiting ring limits one end of the threaded sleeve, and the ball rolls and fits against the lower end of the connecting bar, reducing the resistance of the threaded sleeve as it passes through the connecting bar.

[0017] Furthermore, a bracket is provided at the upper end of the mounting tube, a positioning hole is provided inside the threaded sleeve, a pin with its lower end slidably inserted into the positioning hole is slidably installed inside the bracket, a support ring is sleeved on the outer wall of the pin, a spring is provided between the support ring and the bracket and sleeved on the outside of the pin, and a pull handle is provided at the upper end of the pin.

[0018] Specifically, by gripping the handle, it is easy to apply a pulling force to the pin. After the pin is inserted into the positioning hole, the elastic force of the spring is applied to the pin through the support ring, thereby limiting the threaded sleeve.

[0019] Furthermore, the inner diameter of the return water pipe structure is 25mm, the thickness of the carbon fiber braided reinforcement layer is 0.5mm, the thickness of the aluminum alloy protective shell is 1mm, and the corrugation depth of the stainless steel corrugated pipe is 2mm, the crest spacing is 10-15mm, and the wave height is 1-3mm.

[0020] Specifically, this reduces the weight of the return water pipe structure, makes it less prone to corrosion, and improves its pressure resistance.

[0021] 2. Beneficial effects

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] This utility model has a three-layer composite structure for the pipe body. The inner layer is a 316L stainless steel corrugated pipe, the middle layer is a carbon fiber braided reinforcement layer, and the outer layer is an aluminum alloy protective shell. By combining the corrugated pipe with the fiber reinforcement layer, the weight is reduced while the compressive strength is increased, which solves the problems of heavy weight and short life of traditional return water pipes. It is especially suitable for automobiles with high requirements for lightweighting.

[0024] Meanwhile, the return water pipe structure and the installation pipe adopt a flexible plug-in structure, which realizes quick installation and quick disassembly between the pipes, making it convenient for the installation, disassembly and maintenance of the return water pipe and improving the ease of use.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] Please see Figures 1-5 As shown, this embodiment is a lightweight, high-strength radiator return pipe, comprising:

[0041] The return water pipe structure 100 includes a stainless steel corrugated pipe 104 located inside the return water pipe structure 100, a carbon fiber braided reinforcement layer 103 located in the middle layer of the return water pipe structure 100, an aluminum alloy protective shell 102 located outside the carbon fiber braided reinforcement layer 103, and conical butt joints 101 located at both ends of the return water pipe structure 100.

[0042] The return water pipe structure has an inner diameter of 25mm, a carbon fiber braided reinforcement layer of 0.5mm, an aluminum alloy protective shell of 1mm thickness, and a stainless steel corrugated pipe of 2mm corrugation depth, a crest spacing of 10-15mm, and a wave height of 1-3mm.

[0043] Use of return water pipe structure 100;

[0044] The return water pipe is a key component of the coolant circulation loop. Its structure and performance directly affect heat dissipation efficiency and reliability. Traditional return water pipes are single-layer rubber or metal pipes. The return water pipe structure has a spiral corrugated wall, which compensates for thermal expansion and contraction stress through deformation, while improving pressure resistance and bending resistance. Aluminum-magnesium alloy and composite materials replace traditional steel pipes. The outside is also sprayed with a lightweight heat-insulating coating. The material surface is anodized to resist the chemical corrosion of coolant. The working pressure is ≥1.5MPa and the temperature range is -40℃~150℃. It ensures low-resistance circulation of coolant, maintains heat dissipation efficiency, and avoids the micro-cracks that may be caused by long-term thermal expansion and contraction of the return water pipe. It solves the problems of heavy weight and short life of traditional return water pipes. It is particularly suitable for new energy vehicles, aerospace and other fields with high requirements for lightweighting.

[0045] It is worth noting that the return water pipe structure 100 does not show the water tank interface. It mainly improves the main body of the pipe. The return water pipe is connected through three nodes: radiator outlet, water pump inlet and expansion tank, to ensure efficient circulation and stable pressure of coolant, and to realize system thermal management and fault buffering. In addition, the two ends of the return water pipe structure 100 are equipped with universal tubes to facilitate the angle adjustment of the connector 101.

[0046] Example 2

[0047] Please see Figures 1-5 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0048] as well as;

[0049] The mounting structure 200 includes a mounting tube 201, a plug 211 located at one end of the mounting tube 201 and slidably inserted into the connector 101, a rotating seat 204 fixedly disposed on the outer wall of the plug 211 in a ring array, a rotating shaft 208 rotatably disposed inside the rotating seat 204, a mounting block 207 located at one end of the rotating shaft 208, a retaining bead 215 rotatably disposed inside the lower end of the mounting block 207, a retaining seat 205 fixedly disposed on the outer wall of the connector 101 in a ring array, and a torsion spring 206 sleeved on the outer wall of the rotating shaft 208 and connected at both ends to the mounting block 207 and the rotating seat 204 respectively.

[0050] The inner wall of the connector 101 is provided with a guide ring 214 corresponding to the plug 211, and one end of the guide ring 214 is provided with a sealing gasket 213 that fits into the opening of the connector 101 in a ring-shaped distribution.

[0051] A sealing ring 212 that fits against the outer wall of the plug 211 is embedded in the opening of the connector 101, and a retaining ball 215 is engaged inside the retaining seat 205, the upper end of the retaining seat 205 being arc-shaped.

[0052] One end of the mounting block 207 is provided with a connecting strip 203, the outer wall of the mounting tube 201 is threaded with a threaded sleeve 202, the outer wall of the mounting tube 201 is sleeved with a limiting ring 219 located on one side of the threaded sleeve 202, and the outer wall of the threaded sleeve 202 is rotatably mounted with a ball bearing 218 that rolls and fits against the lower end of the connecting strip 203.

[0053] The upper end of the mounting tube 201 is provided with a bracket 210, the threaded sleeve 202 has a positioning hole 217 inside, the bracket 210 has a pin 209 with its lower end slidably inserted into the positioning hole 217 inside, the outer wall of the pin 209 is sleeved with a support ring 220, a spring 216 is provided between the support ring 220 and the bracket 210 and sleeved on the outside of the pin 209, and the upper end of the pin 209 is provided with a pull handle 221.

[0054] Use of installation structure 200;

[0055] When the return water pipe structure 100 is connected to the radiator outlet and the water pump inlet, the installation pipe 201 represents the connection pipe between the water pump suction pipe and the radiator outlet. The installation pipe 201 is connected to the connector 101 through the plug 211. During this process, the retaining ball 215 slides on the outer wall of the connector 101, applying pressure to the rotating shaft 208 during the compression process. The rotating shaft 208 rotates, causing the torsion spring 206 to twist, which in turn causes the mounting block 207 to rotate and rise with the rotating shaft 208, allowing the retaining ball 215 to enter the positioning seat. During this process, the plug 211 and the sealing ring 212 are pressed and fitted together, and the sealing gasket 213 fills the gap between the plug 211 and the guide ring 214. Then, the threaded sleeve 202 is gripped and rotated, and the connecting strip 203 is compressed by the ball 218, so that the ball 218 fits against the lower end of the connecting strip 203. Located below the connecting strip 203, the 2nd component supports the connecting strip 203. The rotating shaft 208 is limited on both sides by the ball bearings 218 and the retaining ball 215, ensuring the stability of the rotating shaft 208. When the threaded sleeve 202 rotates, the pull handle 221 applies a pulling force to the spring 216 through the support ring 220. The spring 216 contracts under the force. After the positioning hole 217 inside the threaded sleeve 202 aligns with the pin 209, the pull handle 221 is relaxed. The elastic force of the spring 216 drives the pin 209 to be inserted into the positioning hole 217, positioning the threaded sleeve 202 and preventing the threaded sleeve 202 from loosening. The installation of the return water pipe structure 100 is completed by inserting and squeezing, rotating the threaded sleeve 202, and positioning the threaded sleeve 202 with the elastically supported pin 209. The installation process only takes a few seconds. The return water pipe structure 100 is easy to install and disassemble and is convenient to use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
