With the widespread adoption of high-power electronic devices and new energy equipment, Liquid Cold Plates (LCPs) are increasingly replacing traditional air cooling and heat pipes as efficient heat dissipation solutions, becoming a key option for industries such as data centers, new energy vehicles, and 5G base stations. However, the cooling requirements of different devices vary significantly, leading many companies to choose customized LCPs to ensure their performance is perfectly aligned with their systems. During the customization process, several key details require special attention.
Clarifying the heat source parameters is the first step in customization. When providing requirements, customers should specify the power range, heat flux density, and the size and distribution of the heat-generating area. Only with clear thermal parameters can the design team optimally plan the LCP's flow path structure and cooling efficiency, avoiding costly design issues resulting from insufficient or over-designed cooling.
Material selection is crucial. Common LCPs are often made of aluminum alloy or copper. Aluminum is lightweight, affordable, and suitable for high-volume applications. Copper offers better thermal conductivity, but is more expensive and heavier. When customizing, the type of coolant must also be considered to avoid corrosion or leakage issues caused by material and coolant incompatibility.
The flow channel structure design should be tailored to specific needs. Different structures, such as straight-through, serpentine, and microchannel, each have their advantages and disadvantages. Straight-through flow channels offer low resistance and ease of processing, making them suitable for applications with moderate heat dissipation requirements. Microchannels offer high heat dissipation efficiency, but are more difficult and costly to process. The design must strike a balance between performance, cost, and reliability.
The interfaces and mounting method must also be determined in advance. When customizing a Liquid Cold Plate, the interface location, dimensions, and mounting hole layout should be clearly defined to ensure seamless integration with the overall system. Improper interface design can lead to complex piping layouts or poor coolant circulation, compromising overall heat dissipation efficiency.
Quality inspection and delivery time are crucial. Liquid Cold Plates involve high-precision machining and sealing processes, and must undergo rigorous pressure and airtightness testing to ensure no leakage or permeation. Furthermore, the customization contract should clearly specify the design cycle, sample testing time, and batch delivery time, allowing customers to plan their production schedules appropriately.
Customizing a Liquid Cold Plate is a systematic project that requires comprehensive consideration of heat source parameters, material selection, flow channel design, interface installation, and quality inspection. Only by paying attention to these details can the Liquid Cold Plate achieve efficient, stable, and reliable heat dissipation in practical applications.

High-efficiency liquid cooling enabled by a microchannel cold plate.
High-efficiency liquid cooling enabled by a microchannel cold plate. This cold plate interfaces directly with external cooling equipment via its inlet and outlet ports, providing continuous, stable heat removal. Multiple microchannels ensure uniform temperature distribution; even if the flow is not working in individual channels, the remaining paths maintain consistent cooling performance. The combination with the microchannel structure supports rapid heat spreading, reduces temperature gradients, and effectively suppresses local hot spots. Multiple microchannel flow paths ensure smooth and predictable coolant movement, making the design suitable for high-power and high-density thermal loads. Ideal for power electronics, laser systems, RF modules, and other compact high-performance devices requiring efficient liquid cooling.
