Leading technology urgently needs market validation and recognition

At present, Optics Valley has become the largest production base for fiber optic cables, optoelectronic devices, and laser equipment in the field of optical communication and laser in China. Optics Valley can provide a broad market for the use of semiconductor thermoelectric devices, "said a staff member from the Enterprise Service Bureau of the High Tech Zone. Companies like Xinsaier in the high-tech zone have overcome the technical difficulties of semiconductor thermoelectric technology, even surpassing foreign competitors in corresponding technical parameters. They have independently developed products that have been put into production and have received small batch orders, which need to be recognized by the market. More markets are needed to complete localization verification and substitution. It is hoped that by holding this supply and demand docking event, the semiconductor thermoelectric industry in the zone can be further promoted up and down Establish long-term and stable cooperative relationships with enterprises, accelerate the implementation and application promotion of semiconductor thermoelectric materials, devices, and system solutions in the optoelectronic information industry, break the monopoly of foreign semiconductor thermoelectric technology, and achieve independent and controllable core technologies.

The Inside and Outside of Thermal Management of Electronic Devices

Professor Yang Ronggui from the School of Energy and Power Engineering at Huazhong University of Science and Technology was invited to give a technical exchange report. Professor Yang shared the thermal transport issues and management challenges of high-power chips, the thermal transport mechanisms of chip materials and heterogeneous interfaces, as well as micro nano phase change heat transfer and thermal management technologies, providing new ideas for entrepreneurs and bringing a cutting-edge report on the latest development of thermal management technology.

Localization of semiconductor micro thermoelectric modules is just around the corner

Yan Yonggao, a professor at the School of Materials at Wuhan University of Technology and the general manager of Wuhan New Sail Technology Co., Ltd., shared the research achievements in the design, preparation, and performance optimization of high-performance semiconductor thermoelectric materials over the past two decades, as well as the latest progress in the exploration and transformation of achievements in the manufacturing and application fields of semiconductor thermoelectric devices. At the same time, it also introduces New Sail Technology Co., Ltd. and its progress in the industrialization of micro thermoelectric chips.

Mr. Yan mentioned that semiconductor thermoelectric devices have important applications in various fields such as optical communication, infrared detection, industrial lasers, autonomous driving, the Internet of Things, biomedicine, and so on. According to authoritative predictions, the global semiconductor thermoelectric device market will reach 50 to 70 billion RMB by 2035. However, high-end micro thermoelectric modules are almost completely monopolized by foreign countries, with domestic manufacturers having a market share of less than 5%. Nearly 80% of high-end micro thermoelectric modules come from Japan, and Ferrotec Inc. alone accounts for nearly half of the market. At present, the vast majority of high-end micro thermoelectric devices for optoelectronic information enterprises in Optics Valley come from Daiwa Company in Japan.

Mr. Yan proudly said that New Sail Company's self-developed semiconductor thermoelectric modules have obtained authoritative testing and certification, and the material performance excellence, device temperature difference, and other parameters have reached international leading levels. The power consumption of the micro thermoelectric modules developed by Xinsaier Company has decreased by 28% compared to Daiwa Thermomagnetic Company in Japan, and more importantly, the ones New Sail Company produces. At present, the company has built a semiconductor thermoelectric TEC modules production line with a first-class level of automation in China, which can achieve mass production. Welcome optoelectronic information companies from Optics Valley and related companies outside the region to verify the use of the products.
