China Thermoelectric Coolers Reliable Supplier

In China, we welcome new and existing customers to X-Meritan to purchase Thermoelectric Coolers. These are solid-state electronic devices that operate based on the Peltier effect and can achieve cooling or heating functions.

1、When current passes through the PN junction, electrons and holes recombine or separate at the junction, taking away or releasing heat.

2、One side is the cold end (heat absorption) and the other side is the hot end (heat release).

3、By changing the direction of the current, the hot and cold ends can be switched to achieve cooling or heating.

Thermoelectric coolers typically consist of two pairs of N-type and P-type semiconductor arms, a ceramic substrate (usually alumina) for insulation and thermal conductivity, and a conductive copper sheet connecting the arms to form a circuit. When current passes through this pair of dissimilar semiconductor materials (usually N-type and P-type), one end absorbs heat (cooling) while the other releases heat (heating), achieving precise temperature control.

X-Meritan is a supplier and service provider of high-quality semiconductor coolers. We offer customizable services. We collaborate closely with leading global semiconductor refrigeration technology providers, actively promoting the implementation and application of cutting-edge technologies both domestically and internationally, and provide one-stop services to meet our customers' diverse needs.
