Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically to the field of computer heat dissipation, and particularly to a water-cooled radiator. Background Technology

[0002] Computers generate heat when they are working, thus requiring a cooling system to dissipate and cool them. Currently, the most common computer cooling method is air cooling, but air cooling has some drawbacks. Specifically: firstly, the inflow and outflow of air can easily allow dust to enter the computer, affecting its normal operation; secondly, the amount of heat generated by a computer varies depending on the software being used—for example, playing games generates significantly more heat than browsing the web. However, computer cooling systems generally operate at a constant power and cannot adapt to the amount of heat generated, leading to insufficient cooling performance or wasted cooling capacity.

[0003] Based on the above problems, this utility model proposes a water-cooled radiator. Utility Model Content

[0004] To address the problems mentioned in the background above, this utility model provides a water-cooled radiator.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows.

[0006] A water-cooled radiator includes a horizontal cylindrical shell and a horizontal sealing plate that are parallel to each other, and a side cylindrical shell is provided between the ends of the two. There are two side cylindrical shells and they are respectively located at the two ends of the horizontal cylindrical shell. The two side cylindrical shells are side cylindrical shell one and side cylindrical shell two. A heat-conducting pipe is provided in the area between the horizontal cylindrical shell, the horizontal sealing plate, and the two side cylindrical shells. The two ends of the heat-conducting pipe are respectively connected to the two side cylindrical shells. Several heat-conducting pipes are arranged in an array along the extension direction of the side cylindrical shells. A baffle assembly is provided between the horizontal cylindrical shell, the horizontal sealing plate, and the two side cylindrical shells to guide the water medium to circulate and the flow trajectory is continuously curved.

[0007] Furthermore, several fins are arranged between two adjacent heat pipes.

[0008] Furthermore, the partition assembly includes a partition 1 disposed inside the transverse cylindrical shell, which divides the inner cavity of the transverse cylindrical shell into a left chamber and a right chamber that are not interconnected. The upper surface of the left chamber is provided with a water outlet, and the upper surface of the right chamber is provided with a water inlet. The side shell is provided with partition 2 and partition 3, which cooperate with each other. Along the direction of the horizontal shell pointing to the horizontal sealing plate, the inner cavity of the side shell is divided into side chamber 1, side chamber 2 and side chamber 3 in sequence. Side chamber 1 and the left chamber are connected by connecting pipe 3, and side chamber 1 and side chamber 3 are connected by connecting pipe 2. The second side cylinder shell is equipped with a partition four, which points in the direction of the horizontal sealing plate along the horizontal cylinder shell. The partition four divides the inner cavity of the second side cylinder shell into the fourth side chamber and the fifth side chamber in sequence. The fourth side chamber and the right chamber are connected by a connecting pipe one. Partition four is located between partition two and partition three.

[0009] Furthermore, a water inlet is provided on the outer surface of the side shell, and a plug is provided at the water inlet.

[0010] Furthermore, it also includes a fan casing, the two openings of which are connected to the air inlet and air outlet respectively on the computer casing. A cooling pipe is installed inside the fan casing, and the two ends of the cooling pipe extend out of the fan casing and are connected to the water inlet and water outlet respectively. A fan is installed inside the air duct shell.

[0011] The air inlet and air outlet are respectively located on two parallel sides of the computer case.

[0012] Furthermore, the water inlet and the cooling pipe are connected by a water pump.

[0013] Furthermore, there are three fans, namely Fan 1, Fan 2 and Fan 3, which are used to control the switch of Fan 1 to keep it closed.

[0014] Furthermore, it also includes a heat-conducting shell connected to the fins, with a shell cover at the shell opening, and piston one and piston two are fitted inside the heat-conducting shell, with piston two close to the shell cover. The region between piston one and the closed end of the heat-conducting shell stores a thermal expansion medium. A spring one is installed between piston one and piston two, and a spring two is installed between piston two and the shell cover. The elastic coefficient of spring two is greater than that of spring one. The switch 2 for controlling the second fan includes a contact 1 disposed on the side of piston 1 facing piston 2 and a contact 2 disposed on the side of piston 2 facing piston 1, with contact 1 and contact 2 located on the same straight line. The switch three used to control the fan three includes a contact three located on the side of the piston two facing the housing cover and a contact four located on the side of the housing cover facing the piston two. The contact three and the contact four are located on the same straight line.

[0015] Furthermore, air holes are provided on both the piston and the casing.

[0016] Compared with the prior art, the advantages of this utility model are as follows: 1. This solution achieves continuous, curved water flow by setting up several baffles, and the pipes (referring to heat pipes) do not need to be set in a continuous curved shape, making production easier. In contrast, in existing technologies, in order to improve the water cooling effect, the pipes are usually set in a continuous curved shape, which requires welding a bend between two adjacent horizontal pipes. This is more troublesome to produce, and if the welding quality is wrong, water will leak out. If applied to a computer, this will damage the computer. 2. This solution improves and adjusts switches one, two, and three, and works with three fans to adapt to the rising water temperature and adjust the airflow accordingly. This improves the heat dissipation effect on the cooling pipes and ensures that the heat dissipation performance matches the computer's operating conditions in real time, preventing wasted or insufficient heat dissipation.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example 1 Reference Figures 1-3A water-cooled radiator includes a horizontal cylindrical shell 1 and a horizontal sealing plate 4 that are parallel to each other, and a side cylindrical shell is provided between the ends of the two. There are two side cylindrical shells, which are respectively located at both ends of the horizontal cylindrical shell 1. The two side cylindrical shells are named side cylindrical shell one 2 and side cylindrical shell two 3. The side cylindrical shells and the horizontal cylindrical shell 1 are disposed together, and the four of them form a rectangular shape. A heat conduction unit 7 is provided inside the rectangular shape.

[0021] Furthermore, the heat-conducting unit 7 includes two heat-conducting pipes 701 with their openings respectively connected to two side shells. Several heat-conducting pipes 701 are arranged in an array along the extension direction of the side shells, and several fins 702 are arranged between two adjacent heat-conducting pipes 701.

[0022] Reference Figure 2 A partition 101 is provided inside the horizontal cylindrical shell 1, which divides the inner cavity of the horizontal cylindrical shell 1 into a left chamber and a right chamber that are not connected to each other. A water outlet 5 is provided on the upper surface of the left chamber, and a water inlet 6 is provided on the upper surface of the right chamber.

[0023] The side shell 1 2 is provided with partition 2 201 and partition 3 202. The inner cavity of the side shell 1 is divided into side chamber 1, side chamber 2 and side chamber 3 in the direction from the horizontal shell 1 to the horizontal sealing plate 4. The side chamber 1 and the left chamber are connected by connecting pipe 3 10, and the side chamber 1 and the side chamber 3 are connected by connecting pipe 2 9. Furthermore, the outer surface of the side shell 1 2 is provided with a water inlet 11 and a plug (not shown in the figure) is provided at the water inlet 11. By removing the plug, water can be injected into the side shell 1 2 to achieve the purpose of water replenishment.

[0024] The second side shell 3 is provided with a partition plate 4 301, which divides the inner cavity of the second side shell 1 into the fourth side chamber and the fifth side chamber in sequence along the direction of the horizontal shell 1 pointing to the horizontal sealing plate 4. The fourth side chamber and the right chamber are connected by a connecting pipe 8.

[0025] Furthermore, partition four 301 is located between partition two 201 and partition three 202.

[0026] The working process of Example 1: Liquid cooling medium (e.g., water) enters the right chamber through inlet 6, then flows sequentially through connecting pipe 1 8, side chamber 4, heat pipe 701 located between side chamber 4 and side chamber 2, side chamber 2, heat pipe 701 located between side chamber 2 and side chamber 5, side chamber 5, heat pipe 701 located between side chamber 5 and side chamber 3, side chamber 3, connecting pipe 2 9, side chamber 1, connecting pipe 3 10, and the left chamber, finally exiting through outlet 5. This circulation system effectively cools the computer. The technological advantages of this solution are as follows: In existing technologies, in order to improve the heat dissipation effect of water cooling, the pipes are generally designed to be continuously curved. This requires welding a bend between two adjacent horizontal pipes, which is more complicated to produce. Moreover, if the welding quality is wrong, water will leak out. If applied to a computer, this will damage the computer. In contrast, in this solution, by setting up several baffles, the water can flow in a continuous curved manner and the pipes (referring to the heat pipe 701) do not need to be designed to be continuously curved, which makes the production process much easier.

[0027] Example 2 Reference Figure 4 and Figure 5 It also includes a fan casing 12, with two openings of the fan casing 12 connected to the air inlet and air outlet respectively on the computer casing. A cooling pipe 13 is installed inside the fan casing 12, with two openings of the cooling pipe 13 extending out of the fan casing 12 and connected to the water inlet 6 and water outlet 5 respectively. Furthermore, a water pump (not shown in the figure) is installed between the water inlet 6 and the cooling pipe 13.

[0028] A fan 14 is installed inside the air duct shell 12.

[0029] Specifically, the air inlet and air outlet are located on two parallel sides of the computer case.

[0030] The working process of Example 2: The water medium is circulated by a water pump to achieve water cooling. At the same time, the water medium, after its temperature rises, is cooled by the air cooling of the fan 14 in the cooling pipe 13. Its technical advantage is that the air only flows in the fan casing 12 and will not bring dust into the computer.

[0031] Example 3 Reference Figure 5 The fan 14 is equipped with three fans, namely fan one, fan two and fan three, which are used to control the switch of fan one to keep closed, that is, when the computer is powered on and started, fan one will start at the same time.

[0032] Reference Figure 6 It also includes a heat-conducting shell 15 connected to the fins 702, and a shell cover is provided at the shell opening of the heat-conducting shell 15.

[0033] The heat-conducting shell 15 is fitted with piston 16 and piston 2 17, with piston 2 17 close to the shell cover.

[0034] The region between piston 16 and the closed end of heat-conducting shell 15 stores a thermal expansion medium, which is available in existing technology and will not be described in detail, such as air.

[0035] A spring 18 is provided between piston 16 and piston 2 17, and a spring 2 19 is provided between piston 2 17 and the shell cover. The elastic coefficient of spring 2 19 is greater than that of spring 18.

[0036] Piston 217 and the shell cover are provided with air holes (not shown in the figure).

[0037] The switch 2 for controlling the second fan includes a contact 1 located on the side of piston 16 facing piston 2 17 and a contact 2 located on the side of piston 2 17 facing piston 16, with contact 1 and contact 2 on the same straight line.

[0038] The switch three used to control the fan three includes a contact three located on the side of piston two 17 facing the housing cover and a contact four located on the side of the housing cover facing piston two 17. The contact three and the contact four are located on the same straight line.

[0039] The working process of Example 3: When a user uses a computer, the fan starts at the same time the computer is turned on. At this time, the computer generates less heat and the water temperature rises less. Therefore, only the fan needs to be turned on to effectively cool and dissipate heat from the cooling pipe 13. When the computer runs for a long time or the user runs games, the heat generated by the computer gradually increases, the temperature of the water will gradually rise, and the thermal expansion medium will expand, pushing the piston 16 to move. When the piston 16 moves and the switch 2 closes, the fan 2 starts. At this time, the cooling pipe 13 is effectively cooled and dissipated through the cooperation of the fan 1 and the fan 2. Similarly, when piston 16 continues to be pushed by the thermal expansion medium, keeping switch 2 closed and pushing piston 2 17 to move and closing switch 3, fan 3 also starts. At this time, the cooling tube 13 is effectively cooled and dissipated through the cooperation of fan 1, fan 2 and fan 3. In short, it can adapt to the rise in water temperature and activate the corresponding fan to improve the heat dissipation effect of the cooling pipe 13, thereby ensuring sufficient heat dissipation for the computer.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
