The utility model relates to the technical field of heat exchangers, in particular to a heat exchange plate, a printed circuit board type heat exchanger and a hydrogenation machine. A heat exchange plate comprises a plate body provided with a fluid inlet and a fluid outlet; the transition flow channel is arranged at the fluid inlet and/or the fluid outlet, and a plurality of first protrusions arearranged in the transition flow channel; and two ends of the heat exchange runner are respectively communicated with the two transition runners, or one transition runner and the fluid inlet, or the fluid outlet and one transition runner. The first protrusion is arranged in the transition flow channel, the heat exchange medium enters the transition flow channel, the temperature of the heat exchangemedium is evenly distributed through collision of the first protrusion, then the heat exchange medium enters the heat exchange flow channel to conduct heat exchange operation, and it is guaranteed that the temperature of the
