    • A thermoelectric heat exchanger (40) includes a tube (26), a fin (32), and a thermoelectric assembly (42). The tube (26) is configured to contain coolant flowing therethrough and thermally couple the coolant to a surface of the tube (26). The fin (32) is configured to transfer heat from the fin (32) to air passing across the fin (32). The thermoelectric assembly (42) is thermally coupled to the tube (26) and the fin (32). The assembly (42) is configured to heat the fin (32) relative to the tube (26) in response to a voltage source (20) applied to the assembly (42). The assembly (42) includes a plurality of thermoelectric modules (50). Each of the thermoelectric modules (50) is electrically interconnected into a group (52) of series connected modules. The number of modules in each group (52) that are electrically connected in series is determined based on a voltage value of the voltage source (20) and a local temperature difference between the tube (26) and the fin (32) proximate to the group (52).
    • 热电换热器(40)包括管(26),翅片(32)和热电组件(42)。 管(26)构造成容纳流过其中的冷却剂并将冷却剂热耦合到管(26)的表面。 翅片(32)构造成将热量从翅片(32)传递到穿过翅片(32)的空气。 热电组件(42)热耦合到管(26)和翅片(32)。 组件(42)被配置为响应于施加到组件(42)的电压源(20)而相对于管(26)加热翅片(32)。 组件(42)包括多个热电模块(50)。 每个热电模块(50)电连接到串联连接的模块的组(52)中。 基于电压源(20)的电压值和管(26)和翅片(32)附近的局部温度差来确定串联电连接的每个组(52)中的模块数量 组(52)。
