The thermoelectric refrigeration module can achieve heat absorption/release and precise temperature control without the need for transmission components and refrigerant. Features high temperature regulation accuracy, fast response time, green and environmental protection, light weight, low noise, small size, etc
Thermoelectric refrigeration module, referred to as TEM or thermoelectric refrigeration device, refers to a semiconductor device that uses thermoelectric refrigeration as a technical carrier and consists of multiple small or micro heat pumps. Thermoelectric refrigeration technology is a process that controls the direction and magnitude of heat flux density by controlling the direction and magnitude of direct current based on the technical principle of heat transfer when current flows through different conductors.
Compared to traditional mechanical refrigeration, thermoelectric refrigeration modules can absorb/release heat and accurately control temperature without the need for transmission components and refrigerants. With features such as high temperature regulation accuracy, fast response time, green environmental protection, light weight, low noise, and small size, thermoelectric refrigeration modules are more suitable for small cooling capacity scenarios that require high volume, silence, and performance requirements. Convenient, including car refrigerator, car laser radar, car thermostatic seat, car power battery, thermostatic mattress, communication light module, industrial CCD image sensor, electronic refrigerator, medical cold compress equipment, medical PCR detector, aviation detector, etc
Currently, thermoelectric refrigeration modules have been widely used in many scenarios in the fields of semiconductor, automobile, industry, aviation, medical treatment, communication, and other fields. With the rapid development of the downstream application market, its demand continues to increase and its scale expands year by year. According to the “2023-2027 Global Thermoelectric Refrigeration Module (TEM) Industry Deep Market Research and Key Regional Research Report” released by the New Scientology Industrial Research Center, the domestic thermoelectric refrigeration module market size in 2021 has reached 1.8 billion yuan, a year-on-year growth of 13.1%.
The performance of thermoelectric refrigeration module products is greatly affected by the performance of thermoelectric materials. At present, Bi2Te3 (bismuth telluride) is the main thermoelectric material with a high degree of commercialization for thermoelectric refrigeration modules in China, which is widely used in cold chain, medical treatment, optical communication temperature control, and other fields. However, at the same time, Bi2Te3 also has shortcomings such as high cost and poor mechanical performance, which limits its promotion in the field of more high-end and demanding thermoelectric refrigeration modules. Therefore, developing new high-performance thermoelectric materials is one of the urgent needs for the development of the thermoelectric refrigeration module industry in China.
Currently, MgAgSb alloy, Cu_ New high-performance thermoelectric materials such as 2Se, Mg2 (Si, Sn) alloys, N-type Mg3 (Bi, Sb) 2 alloys, which have advantages of low cost, good mechanical properties, and strong environmental protection, have become research and development hotspots. In the future, with the accelerated development of thermoelectric materials in China, the thermoelectric refrigeration module industry is expected to usher in a golden era of rapid development.
According to industry analysts at New ThinkWorld, the main foreign-funded enterprises in China for thermoelectric refrigeration modules currently include Ferrotec, Erlumaro, KELK Ltd., RMT Ltd., Laird Thermal Company, and others; Local enterprises mainly include Fuxin Technology, NAK Thermoelectric, Guanjing Semiconductor, Aoling Refrigeration, Thermoelectric New Energy, Aoliang Electronics, etc.
Currently, foreign enterprises occupy a leading position in the high-end market of thermoelectric refrigeration modules in China. Compared with foreign funded enterprises, local enterprises still have a certain gap in technology, scale, and other aspects. Therefore, in the future, local enterprises need to accelerate the development and application process of new thermoelectric materials, accelerate the improvement of enterprise strength and product advantages, and promote the domestic replacement process of thermoelectric refrigeration modules in the high-end market.
