🔷Product Overview

The Circle Thermoelectric Cooler Peltier is a circular thermoelectric cooling module developed for compact thermal management systems.

Unlike conventional rectangular TEC modules, the circular design can be integrated into equipment where a round mounting area or localized cooling surface is required. The module operates without compressors, refrigerants or mechanical moving components, making it suitable for applications that require compact size, reliable operation and accurate temperature control.

As an experienced Thermoelectric Cooler manufacturer, we provide standard and customized TEC solutions for OEM customers, equipment manufacturers, distributors and engineering projects.

The module can be customized in terms of size, voltage, current, wire configuration, connector and thermal performance to match different system requirements.

🔷Product Features

1. Circular Compact Design

The circular structure provides flexible installation possibilities for equipment with round mounting areas or limited internal space.

2. Precise Temperature Control

Thermoelectric cooling technology allows accurate control of the temperature of the target component or localized area.

3. No Mechanical Moving Parts

🔷Product Structure

The Circle Thermoelectric Cooler Peltier is primarily composed of thermoelectric semiconductor elements, ceramic plates, electrical connections and external wiring.

Main Structure

Ceramic Plate

Provides electrical insulation and a stable thermal transfer surface.

Semiconductor Elements

The semiconductor couples are the core components responsible for thermoelectric heat transfer.

Electrical Connection

The internal electrical circuit connects the thermoelectric semiconductor elements to the external power supply.

Lead Wires

Lead wires can be configured according to the customer's installation requirements.

Thermal Interface

The ceramic surface transfers heat between the TEC module and the cooling/heating target.

🔷Operation Principle / Work Principle

The Circle Thermoelectric Cooler Peltier works based on the Peltier effect.

When DC current passes through the semiconductor elements inside the module, heat is absorbed on one side and released on the opposite side. As a result, one surface becomes cold while the other surface becomes hot.

The basic heat-transfer process can be described as:

DC Power → Semiconductor Elements → Heat Absorption → Heat Transfer → Heat Dissipation

By reversing the direction of the DC current, the hot and cold sides are reversed, allowing the module to operate as either a cooler or a heater.

For this reason, proper hot-side heat dissipation is essential. If heat cannot be removed effectively, the cold-side temperature and cooling capacity will be affected.
