Description

Technical Field

[0001] This utility model relates to the technical field of computer heat sinks, specifically an energy-saving computer chassis water cooling heat sink. Background Technology

[0002] With the continuous improvement of computer hardware performance, especially the increasing power consumption and heat generation of central processing units (CPUs) and graphics processing units (GPUs), efficient heat dissipation has become crucial for ensuring stable system operation and extending hardware lifespan. Traditional air-cooled heat sinks, limited by the thermal conductivity of their materials and heat dissipation area, are gradually failing to meet the demands of high-heat-load scenarios, and their fans generate unpleasant noise at high speeds.

[0003] To overcome the limitations of air cooling, liquid cooling technology is widely used in high-performance computing. Liquid cooling systems utilize a liquid (usually coolant) as a heat transfer medium. The coolant absorbs heat from components such as the CPU through a liquid cooling head, and a pump then delivers the heated liquid to a radiator. Finally, a fan dissipates the heat into the air. Because the specific heat capacity of coolant is much higher than that of air, its thermal conductivity is significantly improved, resulting in superior heat dissipation.

[0004] However, existing conventional computer liquid cooling radiators, especially split-type or most all-in-one (AIO) liquid cooling products, still have the following major drawbacks: Existing liquid cooling systems typically employ a separate modular structure of "liquid head-piping-radiator." The radiator, as a separate and bulky component, occupies a significant amount of space within the chassis, making it less compact. Secondly, to enhance the heat exchange efficiency of the radiator, current solutions generally install multiple high-pressure fans side-by-side on the radiator. These fans, along with the chassis's own intake and exhaust fans, form a multi-fan system. Under high computer load, all fans operate at full speed, resulting in significant cumulative power consumption, which contradicts the energy-saving principles advocated by modern computer design. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving computer chassis water cooling radiator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An energy-saving computer chassis water-cooled radiator includes a heat-conducting plate with several heat exchange tubes connected to both sides. An elastic pressure plate is installed at the bottom of the heat-conducting plate, and mounting plates are connected to both ends of the elastic pressure plate. The top ends of several heat exchange tubes on the same side are connected to an integrated plate. A heat dissipation fin assembly is connected to the middle of each heat exchange tube. A fan is installed at the front end of the heat dissipation fin assembly. A coolant tank is located behind the heat dissipation fin assembly. An output pipe and an input pipe are respectively installed on both sides of the top of the coolant tank. A liquid pump is installed at the connection between the output pipe and the coolant tank. The front end of the output pipe is connected to the rear end of one integrated plate, and the front end of the input pipe is connected to the rear end of another integrated plate.

[0008] As a further embodiment of this utility model: a number of heat-conducting plates are installed at equal intervals at the bottom end of the heat-conducting plate. The number and position of the heat-conducting plates correspond to the heat exchange tubes. The length of the heat-conducting plates is greater than the length of the heat-conducting plate. The top ends of the heat-conducting plates are connected to the bottom ends of the corresponding heat exchange tubes.

[0009] As a further improvement of this utility model: several bases are connected to the front corner of the heat dissipation fin assembly, and a mounting base is provided at the corner of the fan. The mounting base is detachable from the mounting base by bolts.

[0010] As a further embodiment of this utility model: several heat dissipation plates are installed at equal intervals along the vertical direction on both sides of the coolant tank, one end of the heat dissipation plate extends into the coolant tank, and the other end of the heat dissipation plate extends out of the coolant tank.

[0011] As a further embodiment of this utility model: a door is installed at the front end of the coolant tank, a grid-shaped plate is provided inside the coolant tank, a plurality of embedding grooves are provided on the inner top surface of the coolant tank, the top of the grid-shaped plate is embedded in the corresponding embedding groove, and a plurality of liquid passage holes are provided in the middle of the grid-shaped plate.

[0012] This invention offers the following advantages: By using a common integrated plate to connect all heat exchange tubes on the same side, and allowing all heat exchange tubes to pass through a unified heat dissipation fin assembly, it replaces the traditional independent and bulky heat sink module. This integrates the entire heat sink structure into a single unit, resulting in an extremely compact spatial layout and significantly improving the space utilization within the chassis. It overcomes the problems of difficult installation and chaotic airflow in mini-chassis caused by the separate structure of traditional liquid coolers. Secondly, in terms of energy saving, since the heat dissipation fin assembly consists of multiple horizontally arranged fins, it offers low airflow resistance. This allows for the generation of efficient and concentrated cooling airflow by installing only one or a few fans at the front of the fin assembly. This airflow not only effectively dissipates heat from the entire heat dissipation fin assembly and the internal heat exchange tubes but also continues to flow backward, providing auxiliary cooling for the coolant tank at the rear. This achieves "one fan, multiple uses," maximizing the cooling efficiency of a single fan. It changes the traditional practice of requiring multiple fans to be arranged side by side on the heat sink of a liquid cooler, significantly reducing the number of fans required by the cooling system from the source, thereby significantly reducing the heat dissipation energy consumption and operating noise of the entire computer system, achieving the design goal of energy saving and noise reduction.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 4 An energy-saving computer chassis water-cooled radiator includes a heat-conducting plate 13 made of high thermal conductivity copper. Several heat exchange tubes 7 are brazed to both sides of the heat-conducting plate 13. An elastic pressure plate 11, made of spring steel, is bolted to the bottom of the heat-conducting plate 13, providing continuous and stable clamping force. Mounting plates 12 are fixedly connected to both ends of the elastic pressure plate 11, and the mounting plates 12 have standard chassis mounting holes. An integrated plate 6 is connected to the top of several heat exchange tubes 7 on the same side. The integrated plate 6 has a flow channel cavity inside to ensure uniform distribution of coolant to each heat exchange tube 7. A heat dissipation fin assembly 8 is connected to the middle of each heat exchange tube 7 via an expansion joint. A fan 9 is bolted to the front end of the heat dissipation fin assembly 8, and a coolant tank 1 is located behind the heat dissipation fin assembly 8.

[0024] The coolant tank 1 has an output pipe 3 and an input pipe 4 installed on its top two sides, respectively. A liquid pump 5 is installed at the connection between the output pipe 3 and the coolant tank 1. The front end of the output pipe 3 is connected to the rear end of an integrated plate 6 via a quick-connect coupling, and the front end of the input pipe 4 is connected to the rear end of another integrated plate 6 via a quick-connect coupling. The coolant in the coolant tank 1 is transported to the heat exchange tube 7 through the input pipe 4 and the output pipe 3. The coolant in the heat exchange tube 7 passes through the heat conduction plate 13, carrying the heat from the heat conduction plate 13, and dissipates heat from the heat exchange tube 7 through the heat dissipation fin assembly 8 and the fan 9. The heat dissipation fin assembly 8 consists of multiple horizontally arranged aluminum heat dissipation fins with optimized fin spacing to not affect the airflow of the fan 9. At the same time, the fan 9 can dissipate heat from the coolant tank 1 behind it, allowing the fan 9 to dissipate heat from multiple components simultaneously, achieving energy saving.

[0025] Please see Figure 1 , Figure 2 A plurality of heat-conducting fins 14 are evenly spaced at the bottom end of the heat-conducting plate 13, and the heat-conducting fins 14 and the heat-conducting plate 13 are manufactured using an integral molding process. The number and position of the heat-conducting fins 14 correspond to the heat exchange tubes 7. The length of the heat-conducting fins 14 is greater than the length of the heat-conducting plate 13, and the top ends of the heat-conducting fins 14 are welded to the bottom sides of the corresponding heat exchange tubes 7. A plurality of bases 18 are welded to the front corner of the heat dissipation fin assembly 8, and a mounting base 10 is provided at the corner of the fan 9. The mounting base 10 is detachably mounted on the base 18 by bolts, and vibration damping pads are provided between the mounting base 10 and the base 18.

[0026] Example 2: See Figure 1 , Figure 3 Based on Embodiment 1, several heat dissipation plates 15 are installed at equal intervals along the vertical direction on both sides of the coolant tank 1. The heat dissipation plates 15 adopt an aluminum fin structure. One end of the heat dissipation plate 15 extends into the coolant tank 1 by welding, and the other end of the heat dissipation plate 15 extends out of the coolant tank 1, thereby improving the heat dissipation effect of the coolant tank 1. The coolant tank 1 is provided with a filling pipe and a replacement pipe. The filling pipe is equipped with a sealing cap, and the replacement pipe is equipped with a ball valve control switch.

[0027] Please see Figure 3 , Figure 4The front end of the coolant tank 1 is detachably and sealed with a door 2 via a hinge and sealing ring. The door 2 is made of transparent acrylic material for easy observation of the coolant level. A grid-shaped plate 16 is installed inside the coolant tank 1, and the surface of the grid-shaped plate 16 is treated with anti-corrosion coating. Several embedding grooves 19 are provided on the inner top surface of the coolant tank 1, and the top of the grid-shaped plate 16 is embedded in the corresponding embedding groove 19. Several liquid passage holes 17 are provided in the middle of the grid-shaped plate 16. The grid-shaped plate 16 increases the contact area between the coolant and the tank structure, thereby improving heat dissipation. The grid-shaped plate 16 is detachable for easy cleaning and maintenance.

[0028] Working Principle: The heat-conducting plate 13 is tightly attached to the heat-generating components such as the CPU via the mounting plate 12, and the elastic pressure plate 11 at its bottom ensures stable and efficient contact. The heat generated by the heat-generating components is rapidly conducted to the heat-conducting plate 13, and further transferred to several heat exchange tubes 7 directly connected to both sides of the heat-conducting plate 13. In addition, to maximize the heat absorption area, the heat-conducting fin 14 at the bottom of the heat-conducting plate 13 extends the heat conduction path, with its top ends connected to the bottom sides of the corresponding heat exchange tubes 7, forming a highly efficient three-stage heat absorption structure of "heat-conducting plate 13-heat-conducting fin 14-heat exchange tube 7", which quickly and evenly disperses heat into the coolant within the multiple heat exchange tubes 7. The coolant, heated after absorbing heat, flows through the heat dissipation fin assembly 8, which connects the middle of all the heat exchange tubes 7, driven by the infusion pump 5. The heat dissipation fin assembly 8 consists of multiple horizontally arranged fins, and its large surface area effectively conducts heat from the liquid inside the heat exchange tubes 7 to the fin surface. At this time, the fan 9 installed at the front end of the heat sink fin assembly 8 operates, generating a high-speed cooling airflow that passes vertically through the gaps between the fins, forcibly carrying away the heat from the fins and achieving efficient cooling of the coolant. This integrated heat sink fin assembly 8 replaces the traditional bulky heat sink, with a compact structure and smooth airflow path, resulting in low resistance. After passing through the heat sink fin assembly 8, the airflow generated by the fan 9 continues to blow towards the coolant tank 1 located behind it. On one hand, the heat dissipation plates 15 installed on both sides of the coolant tank 1 conduct heat out of its interior, with the airflow assisting in heat dissipation; on the other hand, the grid-shaped plates 16 inside the coolant tank 1 increase the contact area between the coolant and the inner wall of the tank, further enhancing the passive heat dissipation effect of the coolant tank 1. This "one fan, multiple uses" design maximizes the utilization of the airflow resources of a single fan 9, sequentially dissipating heat for the two key components, the heat sink fin assembly 8 and the coolant tank 1, significantly improving the overall heat dissipation efficiency. Thus, it achieves excellent heat dissipation while reducing the number of fans, achieving the goal of energy saving and noise reduction.
