Description

Technical Field

[0001] This invention relates to the field of radiator technology, specifically to a leak-proof liquid-cooled radiator. Background Technology

[0002] Computer cases generate significant heat during use, requiring appropriate heat sinks. Some cases utilize liquid cooling to dissipate this heat. For example, CN213182617U discloses a liquid cooling device for computers, including a case and an early warning mechanism. A liquid reservoir is fixedly connected to the top of the case, with a water pipe on one side of the top of the reservoir and a cooler on top of the reservoir. External liquid cooling pipes are fixedly connected to both sides of the reservoir. A circulating water pump is fixedly connected to one side of the case, with external liquid cooling pipes fixedly connected to both the top and bottom of the pump. A buzzer is installed on one side of the leakage protection pipe, and an L-shaped shunt pipe is fixedly connected to the bottom side of the leakage protection pipe. The buzzer is also connected to the L-shaped shunt pipe. When water leaks, it flows into the L-shaped shunt pipe, causing a small foam ball to float. When the foam ball floats and touches a touch switch, it triggers the buzzer, thus alerting the user to a leak in the liquid cooling device and prompting timely replacement of the internal liquid cooling pipes to prevent damage to electronic components. However, the liquid cooling system used in this computer still has the following drawbacks in actual use:

[0003] 1. Because liquid cooling requires the liquid to flow through the inside of the computer case to absorb heat during the heat dissipation process, and the absorbed liquid contains heat, it does not dissipate in time and flows back into the computer case, resulting in poor heat dissipation.

[0004] 2. After prolonged use, the components of a heatsink will show varying degrees of aging, making it prone to leaks. However, since the heatsink is located inside the computer case, leaks may go unnoticed and could damage other components inside the computer.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing radiators. Summary of the Invention

[0006] The purpose of this invention is to provide a leak-proof liquid-cooled radiator to solve the problems mentioned in the background art, such as poor heat dissipation and the inability to detect leaks in time, which can easily damage other components inside the host.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a leak-proof liquid-cooled radiator, which is provided with a main unit chassis, a liquid storage box for holding coolant is fixed on the side of the main unit chassis, and a circulating water pump for realizing the circulation of coolant is installed on the top of the liquid storage box by bolts.

[0008] include:

[0009] A special-shaped tube, one end of which is connected to the circulating water pump, and the other end of which is fixedly connected to the return pipe. A fixing rod is provided on the side of the vertical section of the return pipe. A shock-absorbing spring is wound around the outside of the fixing rod, and a fixing block is sleeved on the outside of the fixing rod. The fixing block is fixed to the inner wall of the main unit box.

[0010] A fixed box is fixed to the vertical section of the irregular pipe near the circulating water pump, and an acceleration mechanism is provided on the curved section of the irregular pipe. A movable shaft runs through the inside of the fixed box, and a fixed plate is fixed to the side of the movable shaft. A fan blade is fixedly installed at the end of the movable shaft away from the fixed box, and a protective box is sleeved on the outside of the fan blade. The protective box and the fixed box are fixedly connected.

[0011] Preferably, the acceleration mechanism consists of a fixed frame, a metal strip, a movable block, and a compression spring. The fixed frame is sleeved on the outside of the curved section of the shaped tube, and the shaped tube part inside the fixed frame is made of a flexible tube. Therefore, the acceleration mechanism can increase the contact area between the shaped tube and the heat inside the main unit chassis, thereby improving the heat dissipation performance.

[0012] Preferably, a metal strip is fixed to the inner wall of the fixed frame, and the end of the metal strip away from the fixed frame is connected to the movable block. The side of the movable block is connected to the inner wall of the fixed frame through a compression spring. When the metal strip is heated, it bends, thereby pulling the movable block to move.

[0013] Preferably, the metal strip, movable block, and compression spring are symmetrically distributed about the vertical axis of the fixed frame, and the two movable blocks move in opposite directions. The metal strip is a two-way memory alloy, which can compress and deform the shaped tube when the two movable blocks approach each other, while the metal strip remains straight without being heated.

[0014] Preferably, the irregular tube is curved, the bottom of the return tube is inclined, the cross-section of the fixing rod is "L" shaped, and the fixing rod and the fixing block are slidably connected. When the coolant flows in the pipe, the vibration generated can drive the fixing rod to slide in the fixing block. The setting of the shock-absorbing spring has a good shock absorption effect.

[0015] Preferably, the fixed plates are evenly distributed on the movable shaft, and the end of the movable shaft away from the fixed plates extends into the interior of the protective box. The side of the protective box is fixedly connected to one end of the air supply pipe. When the fixed plates are impacted by coolant, the movable shaft can drive the fan blades to rotate synchronously and generate wind.

[0016] Preferably, the other end of the gas supply pipe extends into the interior of the liquid storage box, and the gas supply pipe inside the liquid storage box has a spiral structure. The air outlet end of the gas supply pipe passes through the bottom of the liquid storage box. At the same time, the gas supply pipe and the protective box are interconnected, and the air can enter the gas supply pipe from the protective box. In this way, when passing through the liquid storage box, it has a heat dissipation effect on the coolant inside, and finally the gas with heat is discharged.

[0017] Preferably, a connecting box is fixed on the vertical section of the shaped tube near the return pipe, and movable plates are symmetrically hinged to the inner wall of the connecting box. The movable plates are inclined, and the bottom edge of the movable plates is connected to the inner wall of the connecting box through a return spring. When the coolant impacts the movable plates, it can drive them to rotate, thereby separating the two movable plates.

[0018] Preferably, the side of the movable plate and one end of the connecting line are connected to each other, and an alarm is installed at the other end of the connecting line. The alarm is set on the irregular tube below the connecting box. At the same time, the movable plate, the connecting line and the alarm form a closed circuit. When the flow rate in the irregular tube decreases, the two movable plates move closer to each other to form a closed circuit, so that the alarm will sound to remind of leakage.

[0019] Preferably, the acceleration mechanism is a capillary tube with an arc-shaped cross-section. The capillary tube is located at the break point on the shaped tube, and the capillary tube and the shaped tube are interconnected. By setting the capillary tube, the contact range between the coolant and the heat inside the main unit can be increased when the coolant flows in the shaped tube, effectively improving the heat dissipation effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are: this leak-proof liquid-cooled radiator can accelerate the absorption of heat from the computer case by the liquid during the flow process and dissipate the heat in the liquid after heat absorption in a timely manner, so as to improve the heat dissipation effect on the computer case. Moreover, when the radiator leaks, it can be detected in time to avoid damage to other components inside the computer case. The specific details are as follows:

[0021] 1. When the coolant impacts the fixed plate, the fan blades can be rotated through the movable shaft, thereby generating airflow into the air supply pipe. When the air in the air supply pipe flows through the coolant reservoir, it can dissipate heat from the coolant inside. This prevents the coolant, which is carrying heat, from flowing into the chassis without being cooled in time and flowing back into the chassis. Therefore, it can ensure better heat dissipation for the chassis. Finally, the hot air is discharged, and the continuous output of hot air further enhances the cooling of the coolant.

[0022] 2. When the heat inside the chassis is too high, the metal strip can bend after being heated, which in turn causes the two movable blocks to move closer together, squeezing the shaped tube. After the bent section of the shaped tube is squeezed and deformed, it can increase the area for absorbing heat from inside the chassis, thereby improving heat dissipation performance. When the metal strip is no longer heated, it is in a straight state and causes the movable blocks to return to their original position, releasing the squeezing of the shaped tube. The capillary tube setting can also increase the contact range with heat inside the chassis, effectively improving heat dissipation performance.

[0023] 3. When the movable plate is impacted by the coolant, it can rotate. Therefore, the two movable plates are in a separated state. When the radiator leaks, the coolant flow in the shaped tube will decrease. Therefore, the impact force on the movable plate is smaller and it can rotate to a contact state. In this way, the movable plate, connecting wire and alarm form a closed circuit and generate an alarm to quickly check the leak. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8 The present invention provides the following technical solution:

[0035] Example 1

[0036] The radiator in this embodiment includes a main unit case 1, a coolant reservoir 2 fixed to the side of the main unit case 1, and a circulating water pump 3 for circulating coolant is bolted to the top of the reservoir 2; it includes: a shaped tube 4, one end of which is connected to the circulating water pump 3, and the other end of the shaped tube 4 is fixedly connected to a return pipe 5, and a fixing rod 6 is provided on the side of the vertical section of the return pipe 5, a shock-absorbing spring 7 is wound around the outside of the fixing rod 6, and a fixing block 8 is sleeved on the outside of the fixing rod 6, and the fixing block 8 is fixed to the inner wall of the main unit case 1; a fixing box 9, fixed to the vertical section of the shaped tube 4 near the circulating water pump 3, and an acceleration mechanism is provided on the curved section of the shaped tube 4, a movable shaft 10 passing through the inside of the fixing box 9, and a fixing plate 11 fixed to the side of the movable shaft 10, a fan blade 12 fixedly installed at the end of the movable shaft 10 away from the fixing box 9, and a protective box 13 is sleeved on the outside of the fan blade 12, and the protective box 13 and the fixing box 9 are fixedly connected.

[0037] like Figure 1 and Figures 3-4As shown, the acceleration mechanism consists of a fixed frame 20, a metal strip 21, a movable block 22, and a compression spring 23. The fixed frame 20 is sleeved on the outside of the curved section of the shaped tube 4, and the portion of the shaped tube 4 inside the fixed frame 20 is a flexible tube. The metal strip 21 is fixed to the inner wall of the fixed frame 20, and the end of the metal strip 21 away from the fixed frame 20 is connected to the movable block 22. The side of the movable block 22 is connected to the inner wall of the fixed frame 20 through the compression spring 23. The metal strip 21, the movable block 22, and the compression spring 23 are all symmetrically distributed about the vertical axis of the fixed frame 20, and the two movable blocks 22 move in opposite directions. The metal strip 21 is a two-way memory alloy. When the heat inside the main unit 1 is too high, Heat is transferred back to the metal strip 21, causing the straightened metal strip 21 to bend when heated, which is the two-way memory effect. This causes the movable block 22 to move and pulls the compression spring 23 to stretch. The two movable blocks 22 then move closer to each other, squeezing the bent section of the shaped tube 4. The flattened shaped tube 4 increases the contact area with the heat inside the host case 1, which can effectively accelerate the absorption and dissipation of heat. When the internal temperature of the host case 1 is at a normal level, the metal strip 21 is no longer heated and can return to its straightened state. Then, through the elasticity of the compression spring 23, the two movable blocks 22 can be driven back to their original positions, relieving the squeezing of the shaped tube 4, without affecting the heat dissipation inside the host case 1.

[0038] like Figure 1 As shown, the special-shaped tube 4 is curved, the bottom of the return pipe 5 is inclined, the cross-section of the fixing rod 6 is an "L" shaped structure, and the fixing rod 6 and the fixing block 8 are slidably connected. When the coolant enters the return pipe 5 through the special-shaped tube 4, it can flow through the inside of the main unit 1, absorb the heat inside and discharge it, thus playing a high-efficiency heat dissipation role. When the liquid flows in the special-shaped tube 4 and the return pipe 5, it will generate a certain vibration, which can drive the fixing rod 6 to slide on the fixing block 8. And through the setting of the shock-absorbing spring 7, the shaking of the liquid flowing inside the pipe can be effectively reduced.

[0039] like Figures 1-2 and Figures 5-6As shown, the fixed plates 11 are evenly distributed on the movable shaft 10, and the end of the movable shaft 10 away from the fixed plates 11 extends into the interior of the protective box 13. The side of the protective box 13 is fixedly connected to one end of the air supply pipe 14. When liquid enters the shaped tube 4, it impacts the fixed plates 11 and drives the movable shaft 10 and the fan blade 12 to rotate. The resulting airflow can enter the air supply pipe 14 through the protective box 13. The other end of the air supply pipe 14 extends into the interior of the liquid storage box 2, and the air supply pipe 14 inside the liquid storage box 2 has a spiral structure. Furthermore, the air outlet of the air supply pipe 14 extends through the bottom of the liquid storage box 2, and the air supply pipe 14 and the protective box 13 are interconnected. Therefore, the spiral air supply pipe 14 can increase the contact range with the coolant in the liquid storage box 2. In this way, the coolant that flows back to the liquid storage box 2 through the return pipe 5 can be effectively cooled. Moreover, the hot gas is discharged from the end of the air supply pipe 14. The continuously supplied gas can cool the hot coolant in the liquid storage box 2 in a timely manner. In this way, the coolant can ensure the cooling effect when it flows into the main unit box 1.

[0040] like Figure 1 and Figure 7 As shown, a connecting box 15 is fixed on the vertical section of the shaped tube 4 near the return pipe 5, and movable plates 16 are symmetrically hinged to the inner wall of the connecting box 15. The movable plates 16 are inclined, and the bottom edge of the movable plates 16 is connected to the inner wall of the connecting box 15 through a return spring 17. When the coolant continues to flow in the shaped tube 4, it can impact the movable plates 16 to rotate, thereby causing the two movable plates 16 to separate, which facilitates the passage of coolant. The side of the movable plate 16 is connected to one end of the connecting line 18, and an alarm 19 is installed at the other end of the connecting line 18. The alarm 19 is set with... On the irregular tube 4 below the connecting box 15, the movable plate 16, the connecting wire 18, and the alarm 19 form a closed circuit. When the pipe leaks, the liquid flow in the irregular tube 4 decreases accordingly, thus reducing the impact force on the movable plate 16. The elasticity of the return spring 17 can drive the two movable plates 16 to rotate to the mating state. The movable plate 16, the connecting wire 18, and the alarm 19 form a closed circuit, so the alarm 19 can sound an alarm to quickly check the leakage situation and avoid damage to other components inside the main unit box 1 due to delayed detection.

[0041] Example 2

[0042] like Figure 1 and Figure 8As shown, the acceleration mechanism is a capillary tube 24, and the cross-section of the capillary tube 24 is an arc-shaped structure. The capillary tube 24 is located at the break point on the shaped tube 4, and the capillary tube 24 and the shaped tube 4 are interconnected. Unlike the first embodiment, the acceleration mechanism in this embodiment is a capillary tube 24. By diverting the coolant in the shaped tube 4, the contact range between the capillary tube 24 and the heat inside the main unit 1 is increased, which can effectively improve the efficiency of heat absorption and thus accelerate the speed of heat dissipation from the main unit 1.

[0043] Working principle: such as Figures 1-8 As shown, driven by the circulating water pump 3, the coolant in the storage box 2 can be drawn into the special-shaped tube 4. Through the distribution of the special-shaped tube 4 in the main unit box 1, the heat in the main unit box 1 can be absorbed, and the coolant flows back to the storage box 2 through the return pipe 5 to achieve circulating cooling of the main unit box 1.

[0044] During the cooling process, it can have greater contact with the heat in the main unit 1, and the air can dissipate the heat absorbed by the coolant, thus improving the heat dissipation effect of the main unit 1. Finally, when leakage occurs, the flow rate in the special-shaped pipe 4 decreases, which can trigger the alarm 19 through the contacting movable plate 16, so that the leakage can be checked in time.
