This paper presents the study of the novel thermoelectric heat pipe heat pumping system. Bent heat pipes with sintered powder were applied and positioned oppositely as centrifugal forces worked. Extra normal fan blades were required to improve the fan performance. Tests of fan performance were carried out, followed by the thermal performance, within which eight pieces of thermoelectric devices were applied. The results showed that the system can handle airflow of up to 168.7 m³/hr with the revolving speed of 600 RPM, and maximum static pressure is up to 37 Pa. The system can supply the heat of up to 257.1 W with the coefficient of performance (COP) of up to 1.96.
