Abstract

一种热电阻式发热器，包括：导热外壳（1），其用于与肿瘤组织接触并将热量传导至肿瘤组织；热电阻（3），其位于导热外壳（1）内部通过电流使得自身发热；散热体（2），其位于导热外壳（1）内部并将热电阻（3）产生的热量分散并均匀传导至导热外壳（1）；导热补偿臂（7），其与散热体（2）连接，在其特定位置上的温度与导热外壳（1）上的温度相同或误差在要求的范围之内；温度传感器（6），其安装在导热补偿臂的上述特定位置上，通过采集该特定位置温度值反映出导热外壳（1）的表面平均温度值。该发热器通过调节温度传感器在导热补偿臂上的安装固定位置，使温度传感器感应到的温度与外壳发热区表面温度相同或误差在要求的范围之内，从而达到通过控制器精确控制发热器表面温度的目的。
