排放冷却是对流冷却的另一种。与再生冷却不同，用于排放冷却的冷却剂对推力室冷却吸热后不进入燃烧室参与燃烧，而是排放出去。直接排放冷却剂会降低推力室比冲，因此需要尽可能减少用于排放冷却的冷却剂流量，同时只在受热相对不严重的喷管出口段采用排放冷却。还有一种是辐射冷却，其热流由燃烧产物传给推力室，再由推力室室壁想周围空间辐射散热。辐射冷却的特点是简单、结构质量小。主要应用于大喷管的延伸段和采用耐高温材料的小推力发动机推力室。在组织推力室内冷却时，是通过在推力室内壁表面建立温度相对较低的液体或气体保护层，以减少传给推力室室壁的热流，降低壁面温度，实现冷却。内冷却主要分为头部组织的内冷却（屏蔽冷却）、膜冷却和发汗冷却三种方法。推力室采用内冷却措施后，由于需要降低保护层的温度，所以燃烧室壁面附近的混合比不同于中心区域的最佳混合比（多数情况下采用富燃料的近壁层），造成混合比沿燃烧室横截面分布不均匀，使燃烧效率有一定程度的降低。膜冷却与屏蔽冷却类似，是通过在内壁面附近建立均匀、稳定的冷却液膜或气膜保护层，对推力室内壁进行冷却，只是用于建立保护层的冷却剂不是喷注器喷入的，而是通过专门的冷却带供入。冷却带一般布置在燃烧室或喷管收敛段的一个横截面上。
