How to produce radiator
As a key component in electronic equipment, automobiles, industrial machinery and other fields, the production process of radiators involves many aspects such as material selection, process technology and quality control. The following is the detailed process of radiator production and analysis of industry hot spots.
1. Main steps of radiator production
| production link | Specific content | Technical points |
|---|---|---|
| Material selection | Aluminum alloy, copper, graphene, etc. | Thermal conductivity ≥200W/(m·K) |
| Mold design | 3D modeling and simulation analysis | The error is controlled within ±0.1mm |
| Molding process | Die casting/extrusion/CNC processing | Temperature control ±5℃ |
| Surface treatment | Anodizing/Sandblasting | Film thickness 10-25μm |
| Quality inspection | Thermal resistance test/X-ray flaw detection | Pass rate ≥99.5% |
2. The latest technology trends in the industry (hot spots in the past 10 days)
| Technical field | breakthrough progress | Application direction |
|---|---|---|
| Liquid metal heat dissipation | Gallium-based alloy thermal conductivity increased by 40% | High power chip |
| 3D printed radiator | Microchannel structure accuracy reaches 0.05mm | Aerospace |
| phase change materials | Improved energy storage density of paraffin composite materials | New energy battery |
3. Key control points of production process
1.Die casting link: It is necessary to keep the mold temperature between 220-280℃ and control the injection speed at 3-5m/s to avoid air hole defects.
2.Welding process: When using vacuum brazing technology, the melting point of the solder should be more than 100°C lower than the base material, and the welding strength should reach 80% of the base material.
3.cooling fins: The spacing design needs to follow the formula: S=2.5√(Q/V), where Q is the heat flow and V is the wind speed to ensure maximum heat dissipation efficiency.
4. Market supply and demand data (third quarter of 2023)
| product type | Global production (10,000 pieces) | price trend |
|---|---|---|
| CPU cooler | 12,800 | down 5-8% |
| car radiator | 9,500 | up 3% |
| Industrial grade cooling module | 3,200 | flat |
5. New requirements for environmentally friendly production
According to the latest EU RoHS3.0 standard, radiator production needs to pay attention to:
1. Four new phthalates are added to the banned substances, and the limits are all 0.1%.
2. The scrap aluminum recycling rate needs to reach more than 95%
3. Reduce the energy consumption standard per ton of product to less than 1,200kWh
6. Future development trends
1.Intelligent production: AI quality inspection system can identify micro-cracks in radiators in real time, increasing detection speed by 300%
2.Material innovation: The thermal conductivity of the carbon nanotube composite material laboratory has reached 800W/(m·K)
3.Customized services: Support customers to submit CAD drawings online and complete proofing within 72 hours
It can be seen from the above structured data that modern radiator production is developing in the direction of high precision, intelligence, and environmental protection, and the application of new materials will continue to promote the technological upgrading of the industry.
