The invention discloses a heat exchange device capable of improving flow uniformity. The heat exchange device comprises an inlet connecting pipe, an inlet manifold, flow channels, an outlet manifold and an outlet connecting pipe, the inlet connecting pipe is connected with the inlet manifold, a spiral baffle is arranged in the inlet manifold, the flow channels are connected with the inlet manifold and the outlet manifold, and the outlet manifold is connected with the outlet connecting pipe. The spiral baffle comprises a fixing rod and a spiral piece, and the spiral piece extends in the spiral direction of the fixing rod. According to the heat exchange device, working medium distribution in each flow channel of the heat exchange device is well regulated and controlled, the flow uniformity of the heat exchange device can be greatly improved, and the improvement effect is more and more remarkable along with the increase of the mass and flow of an inlet; meanwhile, the flow uniformity is improved, so that the hea
