This high demand is met by a highly developed and responsive supply chain, a hallmark of China’s manufacturing capabilities. Companies like Jinxi Radiator (www.jinxi-radiator.com) demonstrate this strength, specializing in automotive coolant systems and related heat exchangers.
Types of Liquid Cooling Plates
Several types of liquid cooling plates cater to diverse applications. The choice depends on factors like heat dissipation requirements, space constraints, and cost considerations. These include cold plates, immersion cooling systems, and microchannel cooling plates.
| Type of Liquid Cooling Plate | Description | Advantages | Disadvantages |
|---|---|---|---|
| Cold Plate | A metal plate with channels for coolant flow, directly contacting heat-generating components. | High heat transfer efficiency, relatively simple design, widely used in various applications. | Can be bulky, may require precise machining for optimal performance. |
| Immersion Cooling System | Submerges components directly in a dielectric coolant. | Extremely high heat transfer efficiency, suitable for high-power density applications. | Requires specialized coolants, potentially more complex system design and maintenance. |
| Microchannel Cooling Plate | Features micro-sized channels for enhanced coolant flow and heat transfer. | Extremely high surface area to volume ratio, leading to superior heat dissipation, compact design. | More complex manufacturing process, higher cost. |
Technical Features of Liquid Cooling Plates
Key technical aspects influence a liquid cooling plate’s performance and suitability. These include material, manufacturing process, and design parameters.
| Feature | Cold Plate | Immersion Cooling System | Microchannel Cooling Plate |
|---|---|---|---|
| Material | Copper, Aluminum, or alloys | Dielectric fluids (e.g., mineral oil) | Copper, Aluminum, or alloys |
| Manufacturing Process | Machining, brazing, casting | System integration | Micromachining, etching, bonding |
| Channel Design | Straight, serpentine, or other configurations | No defined channels; direct immersion | Micro-sized channels with various geometries |
| Surface Treatment | Plating, anodizing, coatings | Coolant properties | Coatings, surface enhancements |
| Heat Transfer Coefficient | Varies depending on design and material | Very high | Very high |
| Pressure Drop | Varies depending on design and flow rate | Varies depending on coolant and flow rate | Can be high due to small channel dimensions |
