Description

Technical field

[0001] The present utility model relates to the field of water cooling units, in particular to an improved water cooling unit structure. State of the art

[0002] Existing water cooling manifolds typically consist of two water tanks with copper distribution pipes between them. The water tanks generally have inlet and outlet ports, which are typically located within the same tank and divided into two independent inlet and outlet chambers by a partition. In practice, however, because the fluid flows directly from the water pump into the inlet or outlet chamber, turbulent flow occurs immediately upon entry, leading to turbulence and consequently noise. This also reduces heat exchange efficiency. Furthermore, since the inlet and outlet ports are located on the water tank, connection points are required. Air pockets typically form at these connection points, creating uneven surfaces between the fan and these pockets, which detract from the aesthetic design. Content of the present utility model

[0003] The main objective of this utility model is to propose an improved water cooling unit structure. This aims to improve existing radiator designs by achieving a flat surface on unconnected sections and ensuring that the radiator and fan have identical lengths, thereby avoiding the aforementioned problems.

[0004] To achieve the aforementioned objectives, the present utility model proposes an improved water cooling unit structure comprising the following:

[0005] A water tank comprising a first water tank and a second water tank, with several flat pipes arranged between the first water tank and the second water tank; the flat pipes comprising an outlet pipe, an inlet pipe and a connecting pipe;

[0006] A switching water tank positioned between the outlet pipeline and the inlet pipeline, located in the middle of the connecting pipelines;

[0007] The switching water tank is equipped with a partition wall that divides the switching water tank into an inlet chamber and an outlet chamber.

[0008] The inlet chamber and the outlet chamber each have an inlet and an outlet, which are connected to the opposite ends of the water pump.

[0009] The water pump drives the liquid to flow successively through the inlet opening, the inlet chamber, the inlet pipe, the first water tank, the connecting pipe, the second water tank, the outlet pipe and the outlet chamber, before returning to the water pump to form a circulating flow path.

[0010] The advantages of the present application are as follows: 1. Effectively reduces water flow noise: In conventional designs, the water flow hits the water tank ends at high speed, easily creating turbulence and noise. By relocating the inlet / outlet to a diverter tank located in the center of the cooler and guiding the flow smoothly through piping to the primary water tank, a buffer zone is effectively created. This significantly reduces fluid impact, promotes a more consistent flow, and thus reduces noise. Simultaneously, the design of the primary, secondary, and diverter water tanks effectively increases the fluid volume. 2. Improved aesthetic cleanliness: Conventional coolers have connections at the reservoir location, creating uneven fan mounting surfaces and "air pockets." By integrating the connections into a switchable water tank that matches the width of the cooler, a seamless front surface is achieved. The fans can now be perfectly aligned with the cooler (i.e., the fan length matches the length of both the first and second water tanks), significantly improving visual cleanliness and aesthetics. 3. Optimized flow path design: The fluid path is configured as a U-shaped circuit (inlet → inlet pipe → first water tank → connecting pipe → second water tank → outlet pipe → outlet). This extended flow path increases the duration of heat exchange between the coolant and the radiator, thus improving heat dissipation efficiency. 4. Integrated modular approach: Integrating the water pump interface into the changeover water tank embodies modular design principles. This simplifies external pipe connections, reduces potential leak points, and results in a more compact overall structure for the water cooling system with easier installation. 5. Optimized flow dynamics: Structural improvements to increase flow stability are an effective approach to increasing the overall performance of the cooler.

[0014] As in the Fig. Figures 1 to 6 show an improved water cooling unit structure: A water tank comprising a first water tank 11 and a second water tank 12, wherein several flat pipes 3 are arranged between the first and the second water tanks 11 and 12; the flat pipes 3 comprise an outlet pipe 31, an inlet pipe 32 and a connecting pipe 30; A switching water tank 2, which is positioned between the outlet pipe 31 and the inlet pipe 32 and is located in the middle of the connecting pipe 30; The switching water tank 2 is equipped with a partition 20 that divides the switching water tank 2 into an inlet chamber 21 and an outlet chamber 22. The inlet chamber 21 and the outlet chamber 22 each have an inlet 23 and an outlet 24, the inlet 23 and the outlet 24 being connected to the opposite ends of the water pump. The water pump drives the liquid to flow successively through the inlet opening 23, the inlet chamber 21, the inlet pipe 32, the first water tank 11, the connecting pipe 30, the second water tank 12, the outlet pipe 31 and the outlet chamber 22, before it flows together at the outlet opening 24 and returns to the water pump to form a circulating flow path.

[0015] The advantages of the present application are as follows: 1. Effective reduction of water flow noise: In conventional designs, the water flow hits the water tank joints at high speed, easily creating turbulence and noise. By relocating the inlet 23 / outlet 24 to the switching water tank 2, located in the radiator core, and allowing the water flow to distribute evenly through pipes into the first water tank 11, an effective buffer zone is created. This significantly reduces water hammer, promotes a more consistent flow, and thus reduces noise. Simultaneously, the design of the first water tank 11, the second water tank 12, and the switching water tank 2 effectively increases the fluid volume. 2. Improved aesthetic cleanliness: Conventional coolers have an interface 70 on the side of the water tank, resulting in an uneven mounting surface for the fan 8 and creating a "gap zone". By integrating the interface 70 into the switching water tank 2, which matches the width of the cooler, the entire front surface is seamless. The fans 8 can now be perfectly aligned with the cooler (i.e., the fan length corresponds to water tanks 11 and 12), significantly improving the visual cleanliness and aesthetics. 3. Optimized flow channel design: The water flow path is configured as a U-shaped circuit (inlet 23 → inlet pipe 32 → first water tank 11 → connecting pipe 30 → second water tank 12 → outlet pipe 31 → outlet 24). This extended flow path increases the duration of heat exchange between the coolant and the radiator fins, thus improving heat dissipation efficiency. 4. Integrated modular approach: The integration of the water pump interface (70) into the changeover water tank (2) embodies modular design principles. This simplifies external pipe connections, reduces potential leak points, and results in a more compact overall structure of the water cooling system with easier installation. 5. Optimized flow dynamics: Structural improvements to increase flow stability are an effective approach to increasing the overall performance of the cooler.

[0016] In particular, covers 51 are provided on both sides of the first water tank 11 and the second water tank 12, respectively, and are welded to the first water tank 11 and the second water tank 12. Specifically, the first water tank 11 and the second water tank 12 comprise one-piece formed tubular bodies. Side holes 41 are provided at both ends of the tubular bodies, while the covers 51 have recesses 42 that align with the side holes 41. The recesses 42 extend into the side holes 41. This arrangement effectively forms a frame structure encompassing the first water tank 11, the second water tank 12, and the two covers 51, thereby improving the stability of the connection between the inner flat pipes 3 and the water tanks and reducing the risk of leakage, i.e., achieving a welded seal.

[0017] In particular, the first water tank 11 and the second water tank 12 have first bores 61 and second bores 61 at their respective ends.

[0018] Both ends of the flat pipe 3 extend into the first and second bore 61, are welded and connected there, thus ensuring the flow of the circulating water circuit.

[0019] The first bore 61 and the second bore 61 each have chamfers, and after the installation of the flat pipe 3, spot welds are formed at these chamfered points, thus ensuring a tight seal. In particular, the upper and lower ends of the cover 51 have inwardly projecting stops 52. These stops 52 support the walls of the switching water tank 2 or the connecting pipe 30. The cover 51 effectively increases the structural strength of the water cooling unit structure. At the same time, by protecting the switching water tank 2 and the connecting pipe 30 via the stops 52, the cover 51 significantly reduces the risk of fluid leakage.

[0020] In particular, the front and rear ends of the switching water tank 2 have three bores 63 and four bores 64 respectively, which are welded and attached to the inlet water pipe 32 and the outlet pipe to form a connection and thus create the circulating water circuit.

[0021] In particular, the width of the switching water tank 2 exceeds half the width of the first water tank 11. This means that, in the relative configuration of the flat pipes 3, the number of connecting pipes 30 equals the number of outlet pipes 31 (or inlet pipes 32), or the number of outlet pipes (inlet pipes 32) exceeds the number of connecting pipes 30. This ensures fluid flow. This modifies the conventional design where the number of flat pipes 3 for the inlet and the number of flat pipes 3 for the outlet are identical (if the number were different, there would be a flow discrepancy between inlet and outlet). Consequently, the stability of the constructed flow channel is effectively ensured, and the generation of turbulence is reduced.

[0022] In particular, the length of the fan 8 corresponds to the total length of the first water tank 11 and the second water tank 12. In this embodiment, the side edge of the fan 8 overlaps the wall surfaces of the first water tank 11 and the second water tank 12, thus ensuring consistency. Naturally, in a preferred embodiment, the length of the fan 8 is identical to that of the connecting pipe 30.

[0023] In particular, the partition 20 of the transfer water tank 2 is arranged along its width. The side wall of the transfer water tank 2 has a recess 7, with an inlet 23 and an outlet 24 located on the outside of the recess 7. The inlet 23 and the outlet 24 each have an interface 70. The combined outer diameter of the interface 70 and the transfer water tank 2 corresponds to the outer diameter of the connecting pipe 30, thus ensuring the adaptability and smoothness of the transfer water line. This modifies the traditional design and improves the product's perceived value.

[0024] In particular, the cross-section of the switching water tank 2 has an "L" configuration, as shown in the Fig. 5 and Fig. 6 shown.

[0025] The inlet pipe is shorter than the outlet pipe, thus increasing the cooling length. This means that primary cooling occurs in the section with heat dissipation fins (not shown), particularly for the fluid in the rear section.

[0026] In particular, the chamfers on the first and second bores were deliberately omitted to facilitate the insertion and installation of the pipes and to enable a seamless seal by welding.

[0027] In particular, the interface includes a port.

[0028] In particular, the outer wall of the connection is provided with several spaced-apart barbs, which ensures a stable installation of the cable.

[0029] In particular, the switchable water tank includes an internal water pump, although an external pump can also be used as an alternative. The central positioning of the internal pump minimizes the protrusion during installation, improves fluid stability, and enhances the aesthetics by eliminating the protruding structures commonly found on existing integrated water cooling radiators. Furthermore, the water pump can be bypassed with the fan, reducing external wiring and improving the overall cleanliness of the water cooling radiator.
