Referring to fig. 14 to 20, the heat exchange plate assembly 56 is composed of a plurality of heat exchange plates, each heat exchange plate includes a plate shell 60 and an air duct sheet 70, the plate shell 60 has a raised frame, the air duct sheet 70 is embedded into the plate shell 60, the height of the frame is similar to the thickness of the air duct sheet 70, when the heat exchange plate assembly 56 is assembled, the plate shell 60 of one heat exchange plate compresses the air duct sheet 70 of the next adjacent heat exchange plate, and the frames of the plate shells 60 of the heat exchange plates are mutually overlapped to form the outer wall surface of the heat exchange plate assembly 56. The plate shell 60 is made of a metal material with excellent heat conduction performance, and the cold end of the semiconductor refrigeration piece 46 is attached to the outer wall surface of the heat exchange plate assembly 56, so that the plate shell 60 is cooled, and the plate shell 60 is kept in a low-temperature state. The air duct sheet 70 is made of elastic rubber material, so that after the heat exchange plate assembly 56 is assembled, the plate shell 60 presses the adjacent air duct sheet 70, thereby ensuring the tightness of the heat exchanger 41.
Referring to fig. 14 to 17, the plate 60 is provided with an air inlet 61, an air outlet 62 and a liquid outlet 63, and the air duct sheet 70 is partially hollowed out to form a first air duct 71 and a second air duct 72, and the first air duct 71 and the second air duct 72 are separated by a separation strip 73. After the plate housing 60 is assembled with the air duct sheet 70, the first air duct 71 covers the air inlet hole 61, the second air duct 72 covers the air outlet hole 62, and the first air duct 71, the second air duct 72 and the partition strip 73 cover part of the liquid outlet hole 63, respectively, so that an air return passage is formed between the plate housing 60 and the air duct sheet 70. The flow direction of compressed air on one heat exchange plate is as follows: the air enters the first air duct 71 from the air inlet hole 61 of the adjacent upper heat exchange plate shell 60, flows through the first air duct 71, enters the second air duct 72 through the return air channel, flows through the second air duct 72, and flows out from the air outlet hole 62 of the adjacent upper heat exchange plate shell 60. The gas contacts the surface of the plate shell 60 when flowing in the first air duct 71 and the second air duct 72, the temperature of the plate shell 60 is very low due to the effect of the semiconductor refrigerating sheet 46, the temperature of the gas decreases after contacting the plate shell 60, condensed water is separated out, the larger the contact area between the gas and the plate shell 60 is, the longer the stay time is, the higher the cooling efficiency of the heat exchanger 41 is, and the lower the output compressed air humidity is. Therefore, the raised flow blocking blocks 76 are arranged at the edges of the first air duct 71 and the second air duct 72, and the flow blocking blocks 76 can change the flow direction of the air, so that the compressed air stays on the surface of the plate shell 60 for a longer time, and the heat exchange effect is improved.
The first air duct 71 has a liquid collecting portion 74, the liquid collecting portion 74 is disposed at the tail of the air flow direction of the first air duct 71, the width of the liquid collecting portion 74 is larger than that of the rest of the first air duct 71, condensed water generated after cooling of compressed air flows along with the air, when the compressed air flows to the liquid collecting portion 74, the air flow direction is changed, and the condensed water contacts with the edge of the liquid collecting portion 74 and is blocked. The overlapping portion of the liquid collecting portion 74 and the liquid discharging hole 63 forms a water hole 81 of the heat exchange plate, and condensed water collected at the edge of the liquid collecting portion 74 flows into the water hole 81 and finally is collected into the liquid collecting hole 83 of the partition plate 57 to be discharged. The liquid collecting portion 74 of the first air duct 71 is configured to facilitate collection of condensed water, and can effectively separate compressed air from the condensed water. In other embodiments, the edges of the liquid collecting portion 74 may be arranged in a spiral shape, and this edge structure has a better water collecting effect.

The second air duct 72 has an air return portion 75, the air return portion 75 is disposed at the front portion of the second air duct 72, the width of the air return portion 75 is smaller than the rest of the second air duct 72, and the overlapping portion of the air return portion 75 and the lower liquid hole 63 forms an air return hole 82 of the heat exchange plate. As shown in fig. 18 to 20, the compressed air flows through the first air duct 71 and then enters the water hole 81, the partition bar partially coincides with the lower liquid hole 63, the air passes through the overlapping portion of the partition bar and the lower liquid hole 63, and enters the second air duct 72 from the return air hole 82. The edge of the second air duct 72 connected with the air return portion 75 is curved, which is beneficial to the diffusion of the air flowing from the air return hole 82 in the second air duct 72, and increases the area of the compressed air flowing through the plate shell 60.
Referring to fig. 20, in order to further improve the heat exchange effect of the compressed air, the positions of the return air holes 82 on the adjacent heat exchange plates are staggered, that is, the positions of the return air portions 75 on the air duct sheets 70 of the adjacent heat exchange plates are different, and the return air portion 75 of one air duct sheet 70 is close to one side edge of the second air duct 72, and then the return air portion 75 of the adjacent air duct sheet 70 is close to the other side edge of the second air duct 72. Thus, the air flowing out from the first air duct 71 of a certain heat exchange plate does not directly flow into the air return holes 82 of the adjacent heat exchange plates, but only flows back into the second air duct 72 from the air return holes 82 of the heat exchange plates, so that the air flowing into the heat exchange plates can flow out from the air outlet holes 62 after flowing through the first air duct 71 and the second air duct 72, and the heat exchange effect of the heat exchanger 41 is improved.
