- Function and structure: Single-layer, double-sided ceramic thermoelectric module with alloy semiconductor material inside. Directly converts thermal energy into electrical energy through the thermoelectric effect. - Reliability and environmental impact: High reliability with no pollution. Red wire to positive, black wire to negative. Generates electricity when a temperature difference exists. - Connection and polarity: In practical applications, a multi-parallel configuration is used to tailor output. Multiple units can be connected in parallel to increase current. - Performance and materials: Thermoelectric module provides reliable, pollution-free operation with stable performance under appropriate temperature differences. - Compatibility and usage: Suitable for integration into systems where a temperature gradient can be leveraged to generate power. Exact output depends on temperature difference and configuration. - Use scenarios: - Waste heat recovery from engines, boilers, or industrial processes to power small sensors, monitoring devices, or low-power electronics. - Remote or off-grid sensing and communications equipment that can operate from heat differentials, reducing the need for frequent battery replacements. - Educational, prototyping, or research setups that demonstrate heat-to-electricity conversion in a compact, pollution-free form.
