Thermoelectric refrigeration is gradually emerging in the field of personal care and beauty, with its unique advantages to provide users with more personalized and efficient beauty solutions. This article will introduce in detail a variety of applications of thermoelectric refrigeration in the field of personal care and beauty. 1.Cold compress beauty instrument - Thermoelectric cooling tablets can be used in cold compress beauty instrument to help shrink pores and reduce skin inflammation by rapidly cooling, and can also relieve eye puffiness, dark circles and facial redness and other problems. In addition, the cold compress also helps to improve the absorption efficiency of skin care products, so that the skin is more firm and smooth. 2.Beauty import and export apparatus - In beauty import and export apparatus, thermoelectric cooling sheets can be used to regulate the temperature...

Thermoelectric refrigeration is a solid-state refrigeration technology based on the Peltier effect, which mainly uses the properties of P-N junctions in semiconductor materials. Its characteristic is that when the current flows between the N-type and P-type materials, heat is transferred from one end of the cooler to the other. Because the N-type material has excess free electrons, and the P-type material has insufficient electrons, the excess electrons in the N-type material and the "holes" in the P-type material become carriers. When the carrier moves, the heat then passes through the thermoelectric element, creating a cold and hot temperature difference between the top and bottom of the device. It is worth mentioning that because the phenomenon is completely reversible, when the polarity of the DC power supply changes, the heat will be transferred in the opposite direc...

During the highly anticipated period of June 13-15, 2024, the 17th (2024) International Solar Photovoltaic and Smart Energy (Shanghai) Exhibition of SNEC and PV+kicked off brilliantly at the National Convention and Exhibition Center (Shanghai). This grand event in the photovoltaic energy storage industry has attracted global attention. As a barometer of the photovoltaic industry, the exhibition not only deeply analyzed the technological path and cutting-edge trends in equipment manufacturing, but also accurately positioned the innovative direction of market trends and application modes. Among the dazzling stars of numerous photovoltaic energy storage products, the built-in chiller system in the energy storage cabinet is particularly dazzling. With its excellent temperature control capability, it accurately regulates the temperature of various components of the ene...
