In the current era of rapid technological development, numerous devices generate a large amount of heat during operation. If the heat cannot be dissipated in a timely manner, the performance of the devices will be greatly reduced, and in severe cases, it may even lead to equipment failures. At this point, liquid cooling technology has emerged as a powerful solution for efficient heat dissipation. In the entire liquid cooling system, the liquid cooling pump occupies a core position, just like the human heart, continuously providing power for the heat dissipation cycle.

1. Working Principle of Liquid Cooling Pump

The working principle of a liquid cooling pump is based on fluid mechanics, where an electric motor drives an impeller to rotate at high speed. During the rotation of the impeller, a low-pressure zone is formed in its central area, like a powerful "suction source," which draws in the coolant. As the impeller continues to rotate, the coolant is quickly thrown to the edge of the impeller, gaining strong kinetic energy, and then is delivered at a relatively high pressure and flow rate. In this way, the coolant forms a circulating flow in the closed pipeline system, similar to the circulation of blood in human blood vessels. When the coolant flows through heat sources, such as server chips in data centers and battery modules in new energy vehicles, it can quickly absorb heat and its own temperature rises. Subsequently, the coolant carrying heat is driven by the Shenpeng liquid cooling pump to flow to heat dissipation devices such as radiators. In the radiator, the coolant transfers heat to the external environment, and after the temperature drops, it returns to the inlet of the Shenpeng liquid cooling pump to start a new cycle of heat absorption and dissipation, thereby achieving efficient heat dissipation.

2. Application Fields of Shenpeng Liquid Cooling Pump

A. Data Centers

As the "brain" of information storage and processing, data centers have a large number of dense servers that generate massive amounts of heat during operation. Traditional air cooling technology is inadequate in dealing with such high heat loads. Liquid cooling technology, with its efficient heat dissipation capability, has become a new favorite for data center cooling. In the liquid cooling system of data centers, the liquid cooling pump is mainly responsible for driving the coolant to circulate in the complex pipeline system. The coolant first flows through the cold plates inside the servers, directly absorbing the heat generated by core components such as CPUs and GPUs, and then is pressurized by the liquid cooling pump and transported to cooling towers or other heat dissipation equipment outside the computer room for heat dissipation. The cooled coolant then returns to the server. Take the data centers of large Internet companies such as Tencent and Alibaba as examples. After adopting liquid cooling systems with high-performance liquid cooling pumps, the operating temperature of servers is effectively controlled, the failure rate is significantly reduced, and the overall operating efficiency of the data center is significantly improved.

B. New Energy Vehicles

In the field of new energy vehicles, batteries and motors are core components. Batteries generate a lot of heat during charging and discharging. If the heat cannot be dissipated in a timely manner, the performance and lifespan of the batteries will be seriously affected, and even safety issues may be triggered. Motors also generate heat during high-speed operation, affecting their working efficiency. The liquid cooling pump plays a crucial role in the thermal management system of new energy vehicles. It drives the coolant to circulate in the cooling pipelines of the battery pack and motor, taking away heat in a timely manner to ensure that the battery and motor always work within an appropriate temperature range. For example, Tesla Model 3, through its advanced liquid cooling thermal management system combined with a high-performance liquid cooling pump, has effectively improved the battery's range and service life, and ensured the efficient operation of the motor.

C. Industrial Equipment

In industrial production, many devices such as lasers, welding machines, and injection molding machines generate a lot of heat during operation. Take lasers as an example. If the high heat generated during their operation cannot be dissipated in a timely manner, it will lead to a decrease in laser output power, poor beam quality, and even damage to the internal optical components of the laser. The liquid cooling pump can quickly take away the heat generated by the laser by driving the coolant circulation, ensuring its stable operation. The application of liquid cooling pumps in industrial equipment can not only improve the operational stability and production efficiency of the equipment but also extend the service life of the equipment and reduce the production costs of enterprises.

D. Medical Equipment

In the medical field, some equipment such as magnetic resonance imaging (MRI) machines and computed tomography (CT) scanners generate a lot of heat during operation, which have high requirements for heat dissipation. The liquid cooling pump drives the coolant to circulate, taking away the heat generated by the equipment, ensuring that the equipment operates in a stable temperature environment, thereby ensuring the imaging quality and diagnostic accuracy of medical equipment. For example, in hospital MRI equipment, the liquid cooling system combined with a liquid cooling pump can effectively reduce the temperature of the equipment during operation, reduce image artifacts, and improve diagnostic accuracy.

3. Key Points for Selecting a Liquid Cooling Pump

A. Flow Rate and Head

Flow rate refers to the volume of coolant that the liquid cooling pump can deliver per unit time, and head refers to the ability of the liquid cooling pump to lift the coolant or overcome pipeline resistance. When selecting a pump, it is necessary to accurately calculate the required flow rate and head based on the heat load of the actual application scenario and the complexity of the pipeline system. If the flow rate is insufficient, the coolant cannot take away enough heat in a timely manner, resulting in poor heat dissipation effect; if the head is insufficient, the coolant cannot circulate smoothly in the pipeline, which will also affect the heat dissipation efficiency. For example, in large-scale liquid cooling systems in data centers, due to the large number of servers, high heat load, and long pipelines, it is necessary to select liquid cooling pumps with large flow rates and high heads.

B. Efficiency and Energy Consumption

Efficiency is one of the important indicators to measure the performance of a liquid cooling pump. A high-efficiency liquid cooling pump can achieve efficient circulation of coolant with less electrical energy consumption, thereby reducing the energy consumption of the entire system. In today's environment of advocating energy conservation and emission reduction, selecting a high-energy-efficiency liquid cooling pump is of great significance. Usually, the efficiency of the pump can be evaluated by checking its energy efficiency label or related technical parameters.

C. Reliability and Stability

For many application scenarios, such as data centers and medical equipment, the reliability and stability of the equipment are crucial. As the core component of the liquid cooling system, the reliability of the liquid cooling pump is directly related to the operation of the entire system. Therefore, when selecting a pump, products with reliable quality and high brand reputation should be chosen. High-quality liquid cooling pumps usually adopt high-quality materials and advanced manufacturing processes, with good sealing performance, wear resistance, and corrosion resistance, and can maintain stable performance during long-term operation. At the same time, some high-end liquid cooling pumps are also equipped with intelligent monitoring systems, which can real-time monitor the operating status of the pump, such as flow rate, pressure, temperature, etc. In case of abnormal conditions, they can alarm in a timely manner and take corresponding protective measures.

D. Noise and Vibration

In environments with high requirements for noise and vibration, such as hospitals and offices, the noise and vibration levels of liquid cooling pumps are also important factors to consider when selecting. Excessive noise will not only affect the working environment and personnel comfort but also may interfere with the surrounding precision equipment. Therefore, liquid cooling pumps with low-noise motors, optimized impeller designs, and good shock absorption devices should be selected to reduce noise and vibration. For example, some liquid cooling pumps using magnetic levitation bearing technology can effectively reduce mechanical friction, reduce noise and vibration, and improve the service life of the pump.
