Thermal - Thermoelectric, Peltier Modules: 430891-403

The 430891-403 is a thermoelectric module from Silicon Labs. It utilizes the Peltier effect to operate as a thermoelectric coolant system by applying a temperature gradient to two sides of the module. This profile allows it to function both as a cooler or a heater depending on the direction of current. The product is small in size, making it a great option for applications requiring tight installation spaces, and it can also operate in an array to create larger temperature differentials. Additionally, the module contains a low static power consumption of 0.8W. This makes it ideal for applications where conservation of energy is necessary, such as portable products or battery powered systems.

Application Field

The Peltier modules from Silicon Labs are extremely versatile and can be used in a variety of applications. These include cooling of ICs, LEDs, thermoelectric coolers, small appliances, microprocessor systems, and other compute systems. They have also been used in many medical imaging and laboratory instruments, as well as space exploration to regulate temperature in satellites and other probes. Additionally, it has been used in the automobile industry, where it is employed as a low power heat exchanger.

Working Principle

The Peltier module operates through the Peltier effect, which states that "When a current passes through two dissimilar conductors, one side will heat up and the other side will cool down." The 430891-403 specifically utilizes this effect by applying voltage to the module, which will cause the two sides to heat and cool. The opposite side of the module will either heat up or cool down depending on the direction of the current. The rate of temperature change depends on several factors, including the heat load, the thermal resistance, and the type of semiconductor material. The energy required to power the Peltier module is typically supplied from a power source or battery.

Conclusion

The 430891-403 thermoelectric module from Silicon Labs is an excellent device for application fields requiring a small, low static power consumption and a high cooling or heating capability. It incorporates the Peltier effect for heat regulation, which allows it to be used in a variety of applications, such as cooling ICs, LEDs, and other compute systems. Additionally, it is often used as a low power heat exchanger in the automobile industry or as a temperature regulator in satellites. It is one of the most versatile thermoelectric devices on the market, and can be widely used to accommodate many different needs.
