Description

Technical Field

[0001] This utility model relates to the field of server heat dissipation technology, and in particular to a high-efficiency heat exchange type server liquid cooling system. Background Technology

[0002] A server is a type of computer that runs a network operating system (such as Windows Server, Linux, Unix, etc.) and various server application software (such as Web services, email services, etc.). Servers have high-speed CPU computing power, long-term reliable operation, powerful I / O external data throughput capabilities, and better scalability. To ensure the stable operation of the server and extend its service life, hot-swapping is used to cool it.

[0003] Traditional air cooling is limited by the low thermal conductivity of air, making it unable to quickly remove heat generated inside the server, leading to increased server temperature and affecting its stability and lifespan. Secondly, as the density of internal server components increases, the number and speed of fans required for air cooling also increase accordingly. This not only increases energy consumption and noise but may also cause uneven airflow and localized overheating. Furthermore, the placement of cooling devices cannot be adjusted according to different types of servers, making them inconvenient to use.

[0004] To address the aforementioned problems, this utility model proposes a high-efficiency heat exchange type liquid cooling system for servers. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing air-cooled heat dissipation technology, which is limited by the low heat conduction efficiency of air, making it unable to quickly remove the heat generated inside the server, thus affecting its stability and lifespan, and unable to adjust the position of the heat dissipation device according to different types of servers. Therefore, this invention proposes a high-efficiency heat exchange type liquid cooling system for servers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency heat exchange type liquid cooling heat dissipation system for servers includes a server body and a circulation box. The server body is equipped with a cold plate and a cooling pipe. A circulation pump is fixedly connected to the upper surface of the circulation box. The inlet end of the circulation pump is fixedly connected to a liquid extraction pipe, which is fixedly located inside the circulation box. The outlet end of the circulation pump is fixedly connected to an outlet pipe. Multiple cooling fins are fixedly connected to the circumference of the cooling pipe.

[0008] The liquid outlet pipe is fixedly connected to the cold plate, the cold plate is fixedly connected to the cooling pipe through a connecting pipe, the other end of the cooling pipe is fixedly connected to the return pipe, the other end of the return pipe is fixedly connected to the circulation tank, and the two ends of the cooling pipe are respectively fixedly connected to the mounting plates.

[0009] Four sets of mounting components are respectively located at both ends of the mounting plate for installing cooling pipes.

[0010] In one possible design, the mounting assembly includes a fixed frame and an adjusting frame, the fixed frame and the adjusting frame being diagonally opposite each other and both being L-shaped. Each of the fixed frame and the adjusting frame has a through mounting groove on one side. A first slider is slidably connected to the inner wall of one side of the fixed frame, and a second slider is slidably connected to the inner wall of one side of the adjusting frame. A through screw is threaded between the first slider and the second slider.

[0011] In one possible design, both the fixing bracket and the adjusting bracket have protrusions on their contacting sides, and the two protrusions cooperate with each other.

[0012] In one possible design, the cold plate covers key heat-generating components such as the CPU, memory, and hard drive inside the server body to reduce their temperature.

[0013] In one possible design, the cold plate has multiple cooling channels inside, each with an inlet and an outlet. The inlet and outlet are arranged diagonally, with the inlet fixedly connected to a connecting pipe and the outlet fixedly connected to an outlet pipe.

[0014] In one possible design, a solenoid valve is fixedly connected to the circumference of the outlet pipe.

[0015] In this application, when the system power is turned on, the circulation pump starts working and draws coolant from the circulation tank through the extraction pipe.

[0016] Under the pressure of the pump, the coolant enters the inlet end of the cold plate through the outlet pipe, and then flows in the cooling channel to absorb the heat on the cold plate.

[0017] The coolant flows out from the outlet end of the cold plate, enters the connecting pipe, and then flows into the cooling pipe.

[0018] The coolant continues to flow inside the cooling pipes, while exchanging heat with the cooling fins to enhance heat exchange efficiency.

[0019] The coolant flows back to the circulation tank through the return pipe, completing one circulation cycle.

[0020] Driven by a circulating pump, the coolant continuously circulates, absorbing and carrying away heat from critical components inside the server.

[0021] By adjusting the opening of the solenoid valve, the flow rate of the coolant can be controlled, thereby adjusting the heat dissipation efficiency of the system and meeting the heat dissipation requirements under different operating conditions.

[0022] Regularly check the coolant level and quality, and replenish or replace the coolant in a timely manner to ensure the system operates normally.

[0023] Monitor system temperature changes and coolant flow to promptly detect and address potential faults or anomalies.

[0024] Beneficial effects:

[0025] In this utility model, the high-efficiency heat exchange type server liquid cooling system adopts liquid cooling technology and utilizes the high thermal conductivity of the coolant to absorb and remove heat from key components inside the server more quickly and efficiently, significantly reducing the server's operating temperature and improving the system's stability and lifespan.

[0026] In this invention, the high-efficiency heat exchange server liquid cooling system, compared with the traditional air cooling method, does not require a large number of fans for air convection, thereby reducing the system's energy consumption and noise. Multiple sets of adjustment components can adjust the installation height of the cooling pipes and fix them tightly. Attached Figure Description
