Product introduction
The cold plate is mainly made of high thermal conductivity copper plate as a substrate, and the copper tube embedded or welded through precision bending molding is formed to form a closed coolant circulation channel. Its appearance is usually flat, with a certain thickness and surface area in order to be in close contact with the heat source and achieve efficient heat transfer. The coolant circulates in the copper pipe, absorbs the heat transmitted by the copper plate, and then brings the heat to the water cold plate, and is distributed to the surrounding environment through the external cooling device (such as the radiator, cooling tower, etc.), so as to effectively reduce the temperature of the heating source and ensure the stable operation of the equipment within the appropriate temperature range.
Product working principle
Heat conduction: When the heating element is in contact with the surface of the copper plate of the water-cooled plate, the heat is rapidly transferred from the heating source to the copper plate based on the principle of heat conduction. Because the copper plate has a high thermal conductivity (generally around 300-400 W/(m·K)), the heat can be quickly and evenly diffused to the entire copper plate, making the temperature of the area in contact with the copper tube rise, thus forming a temperature difference between the copper tube and the copper plate.
Liquid cooling cycle: The coolant (usually water or glycol solution) is driven by an external circulating pump and flows into the bent copper pipe. Due to the temperature difference between the copper tube and the heated copper plate around it, heat is transferred from the copper plate to the coolant through the pipe wall, so that the coolant temperature rises and becomes a hot coolant. Under the action of the circulation system, the hot coolant flows along the path of the bend pipe, and finally flows out of the copper pipe into the external radiator for heat dissipation.
Heat dissipation: In an external radiator, the hot coolant dissipates heat by heat exchange with the air. The radiator usually uses a large area of cooling fins and fans to force convection to increase the contact area and heat exchange efficiency between the coolant and the air, so that the coolant temperature is reduced and the coolant is changed back to a low-temperature coolant. The cryogenic coolant is then transported back to the copper tube of the curved copper tube water cooling plate by the circulation pump to begin the next round of cooling cycle, so that the heat generated by the electronic components is continuously taken away and the low temperature operation of the equipment is maintained.
Product features and advantages
Efficient heat dissipation performance: The curved copper pipe has a large heat conduction area and good thermal conductivity, which can quickly transfer heat to the coolant, and the large area design of the copper plate further enhances the heat diffusion ability. Compared with the traditional air-cooled radiator, under the same heat dissipation conditions, the temperature of the heating element can be reduced by 20-30 ° C or more, which significantly improves the heat dissipation efficiency, effectively meets the heat dissipation requirements of high-power electronic equipment and industrial systems, and ensures the stable operation and performance of the equipment. For example, in the CPU and GPU cooling applications of high-performance servers, the temperature is always within the safe range when running under high loads, avoiding crash and calculation errors caused by overheating.
Rapid cooling ability: The unique bend design and optimized coolant channel layout make the coolant flow quickly inside the water cooling plate, improve the heat transfer speed and efficiency, and achieve rapid cooling effect. This is especially important for some application scenarios that are sensitive to temperature changes and require rapid cooling (such as laser equipment, high-frequency electronic equipment, etc.), which can effectively reduce the performance fluctuations and failure risks caused by high temperature of the equipment, improve the working accuracy and stability of the equipment, and ensure the normal operation and production efficiency of the equipment.
Precise bending process: The use of advanced CNC bending equipment and precision mold, can achieve high precision bending molding. Parameters such as the Angle, radius and length of the bend can be precisely controlled within a very small tolerance range to ensure that the layout of the copper pipe inside the water-cooled plate is completely consistent with the design, so as to ensure the flow uniformity and stability of the coolant, improve the consistency of the heat exchange efficiency, and avoid problems such as increased coolant flow resistance and local overheating caused by insufficient bending precision. It provides a solid process guarantee for the efficient and stable operation of the water-cooled plate.
Good structural adaptability: Through precision pipe bending processing, copper pipes can be bent into a variety of complex shapes to adapt to the design needs of different shapes and sizes of water-cooled plates. Whether it is a compact water-cooled plate for small electronic devices, or a large water-cooled plate in a large industrial system, the rational layout of the copper pipe can be achieved through a customized bend design, which makes full use of limited space, improves the space utilization and heat dissipation performance of the water-cooled plate, and is also easy to integrate with other components to meet a variety of application scenarios and equipment structure requirements.
High reliability and durability: Copper pipes and copper plates have good corrosion resistance and mechanical strength, and can operate stably in harsh working environments for a long time. The pumps, pipes and joints in the coolant circulation system are strictly screened and tested to ensure the tightness and stability of the entire water-cooled plate system, reduce the risk of heat failure caused by leakage, corrosion and other problems, improve the availability and maintenance of the equipment, and reduce operating costs and maintenance workload. In addition, the copper pipe structure after bending is optimized, which can effectively resist thermal and mechanical stress, avoid deformation, cracking and other problems due to long-term use, and further ensure the reliability and service life of the product.
Low noise operation: Compared with traditional air cooled radiators, the noise generated by the water cooled plate is extremely low during operation. Because it mainly relies on the natural convection of the coolant and the low-speed fan of the external radiator (even without the fan in some efficient cooling designs) for heat dissipation, the large noise generated by high-speed fan rotation in the air-cooled radiator is avoided, providing a quiet operating environment for noise-sensitive application scenarios (such as libraries, offices, medical environments, etc.). Improve the user experience and work efficiency, but also in line with the development trend of modern electronic devices for low noise design.
