Description

Technical Field

[0001] The present application relates to the field of liquid cooling and heat dissipation, and in particular to a heat dissipation device with stable performance. Background Art

[0002] In today's rapidly advancing technology, as computer hardware performance continues to improve, heat dissipation has become a key factor hindering its further development. While traditional air cooling can meet the needs of daily use to a certain extent, its heat dissipation efficiency and stability are insufficient in high-intensity application scenarios such as high-performance computing, gaming and entertainment, and data centers. It is against this backdrop that liquid cooling technology has emerged. With its superior heat dissipation performance and stability, it has become the new favorite heat dissipation method in the future technology field.

[0003] Liquid cooling uses liquid as a heat transfer medium, transferring heat away from the heat source and dissipating it into the external environment through the flow of liquid. Compared to traditional air cooling, liquid cooling offers higher heat transfer efficiency and greater heat capacity, effectively reducing hardware temperatures and ensuring stable device operation. Specifically, a stable heat dissipation device typically consists of components such as coolant, cooling pipes, a heat exchanger, and a water pump. Driven by the water pump, the coolant flows through the cooling pipes past the heat source (such as the CPU, GPU, etc.), absorbing and removing heat, and then dissipating the heat into the air through the heat exchanger.

[0004] Due to excessive heat in the air, its heat dissipation efficiency will be reduced. Utility Model Content

[0005] In order to improve the problem of reduced heat dissipation efficiency due to air temperature rise, the present application provides a heat dissipation device with stable performance.

[0006] A heat dissipation device with stable performance provided in the present application adopts the following technical solution: a heat dissipation device with stable performance, including a liquid cooling box, a heat exchanger, a circulation pump, and a controller, wherein the heat exchanger is located outside the liquid cooling box, and the inlet and outlet of the heat exchanger are connected to the liquid cooling box through a liquid inlet pipe and a liquid outlet pipe, respectively; a mounting bracket is provided outside the liquid cooling box, and a fan is provided on the mounting bracket, and the air outlet of the fan faces the heat exchanger; a water tank and a water pump are also installed outside the liquid cooling box, and the water tank has a first water outlet pipe and a second water outlet pipe, and a three-way solenoid valve is provided at the connection between the first water outlet pipe and the second water outlet pipe, the outlet of the first water outlet pipe is located at the air inlet of the fan, and the outlet of the second water outlet pipe is located toward the heat exchanger, a temperature sensor is installed on the liquid outlet pipe, and the flow rate of the first water outlet pipe is less than the flow rate of the second water outlet pipe.

[0007] The temperature sensor here has two warning values, divided into high warning value and low warning value. The warning temperature of the high warning value is higher than the temperature of the low warning value. After the coolant in the liquid cooling box absorbs the heat generated by the server, it enters the heat exchanger through the liquid inlet pipe, dissipates the heat of the coolant into the air through the heat exchanger, and then flows back to the liquid cooling box through the liquid outlet pipe. The fan is set to accelerate the heat dissipation of the heat exchanger, which is beneficial to the heat dissipation of the coolant. When the temperature reaches the low warning value, water is discharged from the first water outlet pipe, and the water and air are mixed and blown toward the heat exchanger. When the temperature reaches the high warning value, water is discharged from the second water outlet pipe to directly spray the heat exchanger.

[0008] Optionally, the water tank includes an outer box body and an inner box body that can be separated from the outer box body, and the outer box body is fixed to the liquid cooling box.

[0009] In this way, the inner box can be taken out manually and water can be added separately.

[0010] Optionally, the bottom of the inner box body has a one-way conducting member, the inner wall of the outer box body has a top opening member for opening the one-way conducting member, the first water pipe and the second water pipe are connected to the outer box body, and there is a storage space between the inner wall of the bottom of the inner box body and the bottom of the outer box body.

[0011] First, fill the storage space with water through the inner box, then fill the inner box with water, and then put the inner box into the outer box. The one-way guide member is pushed open, and the water in the inner box is connected with the water in the storage space. The water is discharged from the storage space through the first water pipe and the second water pipe.

[0012] Optionally, the one-way conducting member includes a conducting port, a sealing plate, and a spring. The sealing plate seals the conducting port under the action of the spring, and the sealing plate is located in the inner box.

[0013] When no force is applied, the sealing plate is pulled by the spring to close the conducting opening.

[0014] Optionally, the bottom inner wall of the outer box body has a support column, and the height of the top opening is higher than the height of the support column.

[0015] In this way, a storage space is formed by the height of the support column. When the bottom of the outer box body abuts against the support column, the top opening member will open the one-way conductive member.

[0016] Optionally, a water inlet is provided on the outer box body, and a water flow channel is formed between the inner wall of the outer box body and the outer wall of the inner box body. The water flow channel is connected to the water inlet and the storage space, and a liquid level meter is installed in the storage space.

[0017] In this way, the water inlet can be directly connected to the water pipe. When the water pipe is cut off, the inner box can be taken out to get water. The liquid level meter can control the solenoid valve at the water inlet to replenish water.

[0018] Optionally, the inner box body is provided with a handle for easy removal.

[0019] Optionally, the outlet of the first water outlet pipe is installed with an atomizing nozzle, and the outlet of the second water outlet pipe is installed with a nozzle.

[0020] By adopting the above technical solution, the atomizing nozzle sprays a small flow rate, making it easier for the atomized water to be sucked into the fan and mixed with the air at the fan inlet before being output, achieving a better cooling effect. The nozzle also sprays a large flow rate, which can be used to quickly cool the heat exchanger when the heat exchanger temperature is high. The nozzle has a trapezoidal structure and a large flow rate.

[0021] In summary, the present application has the following beneficial technical effects: by providing the water tank, the first water outlet pipe and the second water outlet pipe, the heat dissipation can be effectively improved, the performance is more stable, and the water can be replenished by removing the inner box when the water supply is cut off.

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] A heat dissipation device with stable performance includes a liquid cooling box 1, wherein heat-releasing components such as servers are placed in the liquid cooling box 1. The liquid cooling box 1 contains a coolant. There are many types of coolants, which can be divided into multiple types according to different usage environments and requirements. Common coolants include water, mineral oil, fluorinated liquid, water-based coolant, oil-based coolant, etc.

[0029] The stable heat dissipation device also includes a heat exchanger 2, a circulation pump 3, and a controller (not shown). The heat exchanger 2 is located outside the liquid cooling tank 1, with its inlet and outlet connected to the liquid cooling tank 1 via a liquid inlet pipe 4 and a liquid outlet pipe 5, respectively. The circulation pump 3 is mounted on the liquid inlet pipe 4.

[0030] A mounting bracket 6 is welded to the outside of the liquid cooling box 1, and a fan 7 is fixed on the mounting bracket 6, with the air outlet of the fan 7 facing the heat exchanger 2. A water tank 16 is also installed outside the liquid cooling box 1, and the water tank 16 has a main body 8, which is connected to the first water outlet pipe 10 and the second water outlet pipe 11 through a three-way solenoid valve 9. A water pump 12 is installed on the main body 8. The water pump 12 applies pressure to allow water to flow out of the first water outlet pipe 10 or the second water outlet pipe 11. The flow rate of the first water outlet pipe 10 is smaller than the flow rate of the second water outlet pipe 11. Specifically, an atomizing nozzle 13 is installed at the outlet of the first water outlet pipe 10, and a nozzle 14 is installed at the outlet of the second water outlet pipe 11. The nozzle 14 is a nozzle 14 with a trapezoidal cross section.

[0031] A temperature sensor 15 is installed on the liquid outlet pipe 5, and the controller is electrically connected to the temperature sensor 15, the three-way solenoid valve 9, the water pump 12, the circulation pump 3 and other electrical components.

[0032] The water tank 16 includes an outer housing 17 and an inner housing 18 that can be separated from the outer housing 17. The outer housing 17 is fixed to the liquid cooling tank 1. The main body 8 is fixed to and connected to the outer housing 17. The bottom inner wall of the outer housing 17 has support columns 19. When the inner housing 18 is placed inside the outer housing 17, it abuts the support columns 19, forming a storage space 20 between the bottom inner wall of the inner housing 18 and the bottom inner wall of the outer housing 17. A water flow channel 21 is formed between the inner wall of the outer housing 17 and the outer wall of the inner housing 18, and the water flow channel 21 is connected to the storage space 20. Specifically, one side wall of the inner housing 18 is concave, thereby forming the water flow channel 21. The outer housing 17 is provided with a water inlet 22, which is connected to the water flow channel 21, thereby connecting the water inlet 22, the water flow channel 21, and the storage space 20 in sequence. A liquid level gauge is installed in the storage space 20, and the liquid level gauge is electrically connected to the control valve. When the water inlet 22 is connected to the water pipe, a solenoid valve is also provided to control water inflow into the water pipe when the liquid level is too low. The solenoid valve is electrically connected to the controller.

[0033] The inner box 18 has a water inlet 23 at the top and a handle 24 fixed thereto for easy removal. A one-way guide is located at the bottom of the inner box 18. A push-opening member 25 is located on the inner wall of the outer box 17 to push the one-way guide open. The one-way guide comprises a guide opening 26, a sealing plate 27, and a spring 28. The sealing plate 27 seals the guide opening 26 under the action of the spring 28 and is located within the inner box 18. Specifically, a connecting ring 29 is located within the guide opening 26. One end of the spring 28 is fixed to the connecting ring 29 and the other end is fixed to the sealing plate 27. The push-opening member 25 is a columnar structure, taller than the support column 19 and smaller in diameter than the guide opening 26.

[0034] In this embodiment, heat exchanger 2 utilizes finned tubes. Finned tubes are essentially conventional tubes with fins added to their outer or inner surfaces to increase the tube's surface area, thereby increasing the heat exchange area and improving heat exchange efficiency. Fins come in a variety of shapes, such as spiral, straight, and corrugated. Finned tubes are typically made of stainless steel or titanium alloy to enhance their corrosion resistance and high-temperature resistance.

[0035] Working process: After the coolant in liquid cooling tank 1 absorbs heat generated by the servers, it enters heat exchanger 2 through liquid inlet pipe 4. Heat exchanger 2 dissipates the coolant's heat into the air, and then flows back into liquid cooling tank 1 through liquid outlet pipe 5. Fan 7 is set to accelerate heat dissipation from heat exchanger 2, which is beneficial for the coolant's heat dissipation. When the temperature reaches the low warning value, water pump 12 starts, and three-way solenoid valve 9 controls the first water outlet pipe 10 to discharge water through atomizing nozzle 13. The water droplets mix with air and are then blown toward heat exchanger 2. When the temperature reaches the high warning value, three-way solenoid valve 9 controls the second water outlet pipe 11 to discharge water through nozzle 14, directly spraying heat exchanger 2. When the temperature returns to below the low warning value, water pump 12 shuts off.

[0036] During normal water inflow, when the water level is too low, the solenoid valve on the water pipe opens, and water flows through the water pipe and water inlet 22 into the flow channel 21, the storage space 20, the conduction port 26, and the inner box 18. When the water supply is cut off, the storage space 20 is first filled with water through the inner box 18, and then the inner box 18 is filled with water. The inner box 18 is then placed into the outer box 17, and the one-way conduction member is pushed open, allowing the water in the inner box 18 to communicate with the water in the storage space 20.
