Product Features:

  • The energy conservation policies currently implemented by the global industry are mostly focused on reducing energy consumption. However, there is no effective and stable working device for the recovery of waste heat energy. Techniques for converting thermal energy into electrical energy using semiconductor grains as thermoelectric materials have tended to be stable. But there are still many designs that use thermoelectric materials that are still stalling. Since thermoelectric materials must have good thermal energy capture capabilities, they must also have good heat dissipation to maintain temperature differences to maintain operation. Therefore, the design that can operate under low temperature environment and low temperature condition can improve the conversion efficiency of the thermoelectric material and increase the proportion of heat energy recovery.
  • Manufacture flexible heat recovery thermoelectric modules. Different from the high-temperature, giant ceramic-based thermoelectric module that is now mature, the flexible contact and thermal end design formed by metal electroforming can improve the power generation sensitivity of the thermoelectric module, with a small temperature difference. The current can be generated for energy recovery within a few seconds of contact with the heat source, and an optimized thermoelectric conversion efficiency can be obtained.
