The invention relates to a dosing module (10) for dosing an operating/auxiliary material into an exhaust gas flow (46) which flows through an exhaust gas system (42) of an internal combustion engine.The dosing module (10) is cooled by means of a cooling medium. At least one heat pipe (56, 96) extends between the heat exchanger (50, 110) through which the cooled medium flows from the inlet side (52) to the outlet side (54) and the dosing valve (18), said heat pipe causing a heat flow (68) from the dosing valve (18) to the heat exchanger (50, 110). 本发明涉及一种用于将运行/辅助材料配量到废气流(46)中的配量模块(10)，所述废气流流过内燃机的排气系(42)。所述配量模块(10)借助冷却介质冷却。在被冷却介质从入口侧(52)向出口侧(54)流过的热交换器(50、110)和配量阀(18)之间延伸有至少一个热管(56、96)，所述热管引起从所述配量阀(18)到所述热交换器(50、110)的热流(68)。
