Provided is a countercurrent type direct-heating heat exchanger having high heat exchange efficiency. This countercurrent type direct-heating heat exchanger A, which causes a heating subject fluid 1 and a heat medium 2 to flow counter to each other, bringing the heating subject fluid 1 and the heat medium 2 directly into contact with each other and performing a heat exchange, is equipped with a container 10, and one or more inclined plates 20 which are provided inside the container 10 and from the downstream edge part 21 of which the heating subject fluid 1 flows down. Multiple teeth 22 are provided at the downstream edge part 21 of some or all of the inclined plates 20. The heating subject fluid 1 flowing down from the downstream edge part 21 is divided by the teeth 22 and forms striated gaps. Consequently, the contact area between the heating subject fluid 1 and the heat medium 2 is increased, thereby increasing the heat exchange efficiency. |
