🔷Product Structure

The TEC1-24104 is a standard single-stage solid-state thermoelectric cooling module engineered with a mature laminated assembly structure, featuring a 60×60mm large-format flat outer dimension and 241 pairs of high-performance thermoelectric couples.

🔷 Operation Principle

The TEC1-24104 thermoelectric cooling module operates based on the fundamental physical phenomenon known as the Peltier Effect, which realizes active heat transfer and precise temperature control through solid-state electrothermal conversion. Different from traditional compression refrigeration systems that rely on mechanical motion and chemical refrigerants, this module achieves bidirectional cooling and heating purely by adjusting DC input current and voltage, delivering clean, stable, and responsive thermal management without mechanical noise, vibration, or fluid consumption. As a single-stage thermoelectric component with 241 pairs of PN semiconductor junctions and a 60×60mm large heat-exchange surface, the product features uniform heat conversion efficiency and consistent temperature control performance for medium-power precision cooling scenarios.

1. Basic Thermoelectric Conversion Theory

The core working principle relies on carrier heat transfer inside semiconductor materials. The TEC1-24104 module consists of densely arranged N-type and P-type thermoelectric grains. When a direct current passes through the series-connected PN junction array, electrons and holes generate directional migration inside the semiconductor crystals. During carrier movement, heat energy is continuously absorbed from one side and released from the other side, forming a stable temperature difference between the two ceramic substrate surfaces.

Under standard DC driving conditions, the current direction determines the thermal direction: one surface acts as the cold side to absorb ambient heat for cooling, while the other surface acts as the hot side to export accumulated heat for heat dissipation. Reversing the input current will swap the cold and hot sides, enabling reversible heating function. This bidirectional adjustable characteristic is the core theoretical basis for constant-temperature maintenance of the TEC1-24104 module.

2. Internal Heat Transfer Mechanism

With 241 groups of high-consistency thermoelectric couples working synchronously, the TEC1-24104 forms a uniform and efficient internal heat transfer network. After power-on, each PN junction independently completes heat absorption and heat release circulation. The 60×60mm large-area flat structure ensures synchronous thermal response of the entire working surface, effectively avoiding local temperature imbalance and heat concentration caused by insufficient coverage of small-size modules.

The high-thermal-conductivity alumina ceramic substrates on both sides serve as thermal transition layers. The cold-side ceramic quickly collects environmental heat and conducts it to the internal semiconductor grains; the hot-side ceramic rapidly exports the converted heat to external heat dissipation structures such as heat sinks and water-cooling plates. This continuous closed-loop heat migration realizes sustained cooling and temperature reduction of the target working environment.

3. Temperature Difference and Power Regulation Principle

The cooling capacity and temperature difference of the TEC1-24104 are linearly adjustable within the rated working range by modifying the input DC voltage and current. When the working current increases gradually, the carrier migration speed accelerates, the single-cycle heat transfer capacity increases, and the module outputs higher cooling power to form a larger temperature difference. When the current decreases, the cooling power drops accordingly to achieve low-power constant-temperature operation.

Under the standard test condition (Th=27℃), the module reaches its optimal working efficiency within the rated current range, achieving a maximum temperature difference of 68℃ and stable medium-power cooling output. Reasonable power adjustment can effectively avoid excessive current-induced thermal saturation and performance attenuation, ensuring long-term stable and low-loss operation of the module.

4. Constant-Temperature Control Logic

Cooperating with an external professional temperature control circuit, the TEC1-24104 realizes intelligent closed-loop constant-temperature control. The temperature sensor feeds back real-time ambient temperature data to the control system. When the actual temperature is higher than the set value, the module increases cooling power to reduce the temperature; when the temperature is lower than the set threshold, the system adjusts current or reverses polarity to switch to heating mode. This real-time dynamic adjustment maintains high-precision constant-temperature status within a fixed range.

5. Working Characteristics and Compliance Principle Statement

The TEC1-24104 adopts pure solid-state electric-thermal conversion working mode, with no mechanical moving parts, no refrigerant consumption, no chemical emissions, and no operating noise. The working principle conforms to green energy-saving and environmental protection standards, fully complying with RoHS and international electronic product safety specifications.

It must be noted that the thermoelectric module generates heat while working. To ensure normal operation and service life, the hot side must be equipped with a matched heat dissipation device. Professional driving and heat dissipation configuration can prevent thermal accumulation failure and ensure that the module works within the compliant and safe parameter range for a long time.
