Many users inquire about the comparison between air cooling and semiconductor cooling: Our store mainly considers the comprehensive effect, and mainly develops and designs air cooling. The reason is that the owner of semiconductor refrigeration has also done a lot. After testing and user feedback, the problems are as follows: 1. Compared with fans, semiconductors are large in size and need to be conducted through heat exchange to dissipate heat. General cameras or computers are currently mainly good-quality material shells. The semiconductor structure with a small area has local cooling, and there is no cooling area around. Heat needs to be transferred, which reduces the overall efficiency. If the cooling plate is increased, the power consumption increase greatly, because an external fan is also required to dissipate heat. 2. The installation requires tight fitting and thermal conductive silicone or metal, which brings about the problem of structural weight and efficiency. The problem of tight fitting needs to be solved, and the installation structure is troublesome. 3. There is another important problem. The weight, portability and power consumption are much those of fans, and some have condensation due to temperature difference (our products not condense). 4. The fan has high heat dissipation efficiency, adopts high-speed and low-speed gears, has a large heat dissipation area, and can quickly cool down. Weight, volume, writing, and disassembly are very convenient. After comprehensive evaluation, the store owner uses semiconductor refrigeration as a supplement to individual products, mainly for equipment that ordinary air cooling cannot handle, such as Micro-single-lens cameras, mobile phones and other equipment.
