Water type mold temperature machine cooling is the problem?
Heat sinks and high-speed fans can be used for rapid cooling. The thermal conductivity of each material is different, arranged in descending order of thermal conductivity, namely silver, copper, aluminum, and steel. However, if using silver as a heat sink would be too expensive, the best solution is to use copper. Although aluminum is much cheaper, it is clear that the thermal conductivity is not as good as copper is only about 50 percent more than copper.
At present, the commonly used heat sink materials are copper and aluminum alloys. Metal tube float flowmeters have their own advantages and disadvantages. The thermal conductivity of copper is good, but the price is more expensive and the processing is more difficult. The weight of a lot of pure copper radiators exceeds the limit of the weight of the CPU. The electromagnetic flowmeter has a smaller heat capacity and is easily oxidized. The pure aluminum is too soft to be used directly, and all aluminum alloys used are able to provide sufficient hardness. The advantages of aluminum alloys are low price and light weight, but the thermal conductivity is much lower than that of copper. Some heatsinks take their own advantage, and a copper plate is embedded on the base of the aluminum alloy heatsink.
