摘　　要：该研究结合热电理论推导出了制热性能系数、电流与冷热端温差的解析式,并搭建实验台进行研究,分析了水源温度、电流和水冷板流量对制热性能的影响。结果表明:制热性能系数随水源温度的升高而增大,在实验范围内可达2.15;随着冷热端温差的增加,最大制热性能系数所对应的电流也不断变大,当温差由23℃增至34℃时,最佳工作电流由3.0 A增至3.5 A。The analytic formula among the heating performance coefficient(COPh),the current intensity and the temperature difference between hot and cold sides(△Thc)was derived based on the theory of thermoelectric. An experimental platform was set up to study the thermal performance of thermoelectric heat pumps under different working conditions, and the influences of chilled water temperature, current intensity and water-cooled panels flow rate on the thermal performance were investigated. The results show that the COPh increases with the increase of chilled water temperature, and the COPhcan reach up to 2.15 within the experimental range. Furthermore, as △Thc increases, the working current corresponding to the optimal thermal performance also increases. The optimal current is 3.0 A and 3.5 A respectively when △Thc is 23 ℃ and 34 ℃.
