On December 24, Gelonghui reported that Appotronics Corporation (688007.SH) stated on the interactive platform that electronic products with complex structures and high heat generation generally require cooling systems to ensure that the internal temperature environment of the equipment is suitable, that the equipment runs normally, and that its lifespan is extended. Therefore, selecting appropriate cooling components is of high importance and necessity in product design. Currently, cooling technology is mainly divided into two categories: air cooling and liquid cooling, both of which the company has patented. Depending on the cooling requirements, if the cooling demand is limited, air cooling is considered; if the cooling demand is higher, liquid cooling is usually considered. Among them, liquid cooling is further divided into circulating water cooling and immersion cooling based on cooling demands and whether the liquid is in direct contact with the heat source. The company has already implemented circulating water cooling in some cinema and professional display projection products due to high cooling demands; at the same time, because immersion cooling has higher cooling efficiency, the company has also conducted research and development and technical layout for immersion cooling, forming a certain patent reserve. In the future, the company will continue to closely track industry trends and actively layout frontier technologies.
