Server Cooling Solutions
Background introduction of server cooling solutions
With the continuous development of information technology, many enterprises have been equipped with servers as intermediate nodes for data exchange. In some large companies, dozens or hundreds of servers are often placed in the computer room. These servers run simultaneously, processing With a lot of data. When the server is running, it will inevitably emit heat. The larger the server, the greater the heat it emits when it is working. The increase in heat will increase the temperature of the server’s working environment. It will cause the server to fail to operate normally or even be damaged, so the heat dissipated during the working process of the server must be properly handled.
At present, the server is usually cooled by exchanging hot and cold air, and the high-temperature air and low-temperature air in the working environment of the server are continuously circulated to reduce the ambient temperature, but the thermal conductivity of the air is only 0.024W/m· K, so after the low-temperature gas enters the working environment of the server, the heat of the server is transferred to the low-temperature air slowly, resulting in that although the ambient temperature drops, the temperature of the server itself does not drop significantly, and the cooling is performed by exchanging hot and cold air During the process, airflow will be generated. When the cold air blows to the server, it will carry a lot of impurities and dust to the server. These magazines and dust will enter the server from the heat dissipation port of the server. With the increase of use time, these Impurities and dust continue to accumulate inside the server and cover the internal components of the server, so that the heat of the internal components of the server is blocked by this layer of impurities, which further reduces the cooling efficiency of the server. At the same time, when the dust accumulates too much, it will also cause a short circuit in the server circuit Or poor contact, resulting in damage to the server.
The cooling problem of server hardware equipment is mainly due to the large amount of heat generated by its high-performance computing. If the heat cannot be discharged in a timely and effective manner, it will lead to overheating of the hardware equipment, thereby affecting the stability and performance of the server. Therefore, it is very important to solve the cooling problem of server hardware equipment.
Several server cooling solutions
1. Air cooling system
Air cooling systems are one of the most widely used server cooling solutions today. It uses fans to blow cooling air into the server chassis and heat away through the cooling fins. The air cooling system has problems such as high noise and poor heat dissipation.
2. Water cooling system
A water cooling system is a more advanced cooling solution that introduces cooling fluid into the server chassis through a water cooler and removes heat through the cooling fins. Compared with the air cooling system, the water cooling system has better heat dissipation effect and noise reduction effect. Water cooling systems require additional water sources and piping, and there is a risk of water leakage.
1. Phase change material heat dissipation technology
Phase change material cooling technology is an innovative cooling solution. It uses the characteristics of phase change materials to release or absorb heat when the temperature changes, to achieve cooling of server hardware equipment. Compared with traditional cooling technology, phase change material heat dissipation technology has higher heat dissipation efficiency and more stable temperature control.
2. Heat pipe technology
Heat pipe technology is a technology that uses liquid to conduct heat in a closed pipe. It conducts heat from the device to the heat pipe by contacting the heat pipe with the server hardware device, and then takes the heat away through the conduction of the heat pipe. Heatpipe technology provides efficient, reliable heat dissipation and is suitable for server hardware devices of all shapes and sizes.
3. Direct liquid cooling technology
Direct liquid cooling technology is a cooling solution that introduces coolant directly into the server hardware. It cools the hardware equipment by passing the coolant through the heat sink to take away the heat. Direct liquid cooling technology has the characteristics of high efficiency and low noise, but requires more complicated design and maintenance.
The cooling of server hardware equipment is an important link to ensure the normal operation of the server. This article introduces traditional cooling solutions, such as air cooling systems and water cooling systems, as well as some innovative cooling solutions and technologies, such as phase change material heat dissipation technology, heat pipe technology and direct liquid cooling technology. These solutions and technologies play an important role in improving cooling efficiency, reducing noise and ensuring server stability. With the continuous development of technology, more innovative cooling solutions and technologies will be introduced into the cooling field of server hardware equipment to further improve server performance and stability.
