On the machining method of metal micro groove

2022-12-13

Metal micro groove processing methods mainly include the following:

1、 Extrusion by traditional process. Extrude raw materials or steel plates to form tapping channels, and then seal them. This kind of need extrusion mold, high cost, cycle factory, not suitable for small batch diversified processing.

2、 Cutting, milling. It also belongs to the category of traditional machining. The depth and width of metal micro groove processing are limited to a certain extent. The size of the cutter head determines the width and depth of the micro groove. Generally, it is not suitable for large batch and intensive micro groove processing, with long cycle and low productivity. Due to the stress of product materials, it is easy to deform.

3、 Etching process is used for metal micro groove processing. Combined with traditional technology, further excavation. Etching technology can solve some difficulties in machining capillary metal micro grooves. For example, fine micro grooves and extremely narrow micro grooves are processed. When the etching process is used to process the micro groove, the material is almost free of force, so it can process various thicknesses, such as stainless steel 304316, various copper and copper alloys, Hastelloy, molybdenum and other rare metals. At the same time, some special-shaped micro grooves, S-shaped micro grooves, Z-shaped micro grooves and straight micro grooves can be processed.

Metal micro groove processing

characteristic

1. Super thermal conductivity:

The micro groove group composite phase change cooling technology (MGCP) has the superconducting heat capacity, which is 10000 times higher than that of aluminum substrate. This technology can send heat to each heat dissipation surface in time.

2. Super cooling capacity:

The heating capacity is 100 times higher than that of forced water cooling and 1000 times higher than that of forced air cooling. There is a huge difference in heat transfer capacity.

3. No power cooling:

Passive cooling, no fan or water pump, no energy consumption for cooling, no power operation, energy saving. The energy generated by high-power power electronic devices is used ingeniously to evaporate the heat medium to generate kinetic energy and potential energy. The steam flows to the condenser to release heat and condense into liquid. With the capillary force and liquid gravity of the micro grooves of the heat collector, it returns to the heat collector close to the high-power power electronic devices, thus realizing a closed heat dissipation cycle without external power.

4. Light weight and small volume:

The weight is less than 25% of the existing radiator, and the volume can be less than 20%.

5. High reliability:

The device is simple and compact, stable in operation, without startup problems, and far more reliable than fans, water cooling and heat pipe radiators.

6. Low cost and environmental protection:

The product cost is less than the radiator of fan, water cooling and heat pipe; The phase-change working medium is environmentally friendly, with small amount and no consumption.

7. Waste heat utilization:

The heat (waste heat) generated by high-power power electronic devices can be changed into 50 ℃~60 ℃ hot water for daily life, replacing the electric water heater to achieve energy conservation.
