In conjunction with shown in Figure 12 to Figure 18, the heat exchanger plates components 56 are by multiple plate packages at each heat exchanger plates include one A plate shell 60 and an air duct piece 70, the raised frame of plate shell 60, in 70 insert plate shell 60 of air duct piece, the height of frame Close with the thickness of air duct piece 70, when heat exchanger plates components 56 are assembled, the plate shell 60 of a certain heat exchanger plates compresses adjacent next heat exchange The air duct piece 70 of plate, 60 frame of plate shell of each heat exchanger plates, which is overlapped mutually, constitutes the outside wall surface of heat exchanger plates components 56.Plate shell 60 It being made of the excellent metal material of heating conduction, the cold end of semiconductor chilling plate 46 is bonded with the outside wall surface of heat exchanger plates components 56, Plate shell 60 is set to cool down, plate shell 60 is maintained at low-temperature condition.And air duct piece 70 is made of flexible rubber material, exchanges heat in this way After board group part 56 assembles, plate shell 60 can squeeze adjacent air duct piece 70, guarantee the leakproofness of heat exchanger 41.

In conjunction with shown in Figure 12 to Figure 15, the plate shell 60 is equipped with air inlet 61, venthole 62 and lower liquid hole 63, the wind Piece 70 part hollow out in road forms the first air duct 71 and the second air duct 72, passes through separation between the first air duct 71 and the second air duct 72 Item 73 separates.After plate shell 60 and air duct piece 70 assemble, the first air duct 71 covers air inlet 61, and the second air duct 72 covers outlet Hole 62, the first air duct 71, the second air duct 72 and divider 73 are covered each by part lower liquid hole 63, in this way in plate shell 60 and air duct piece Return air channel is formd between 70.Flow direction of the compressed air on one piece of heat exchanger plates is as follows: from adjacent upper one piece of heat exchanger plates plate shell 60 air inlet 61 enters the first air duct 71, passes through return air channel into the second air duct 72, second after flowing through the first air duct 71 It is flowed out after flowing from the venthole 62 of adjacent upper one block of heat exchanger plates plate shell 60 in air duct 72.Gas is in the first air duct 71 and the second air duct The contact of when 72 flowing and 60 surface of plate shell, due to the effect of semiconductor chilling plate 46,60 temperature of plate shell is very low, gas and plate shell 60 Temperature declines after contact, and condensed water is precipitated, and the contact area of gas and plate shell 60 is bigger, and the residence time is longer, then heat exchanger 41 Cooling efficiency it is higher, the compressed air humidity of output is lower.Therefore it is set at the edge in the first air duct 71 and the second air duct 72 The baffle block 76 of protrusion is set, baffle block 76 can change gas flow, make compressed air when 60 superficial residence of plate shell is longer Between, improve heat transfer effect.

First air duct 71 has liquid collecting portion 74, and the gas flow tail portion in the first air duct 71 is arranged in liquid collecting portion 74, collects The width in liquid portion 74 is greater than 71 rest part of the first air duct, and the condensed water generated after compressed air cooling can flow together with gas Dynamic, when compressed air flowing is to liquid collecting portion 74, gas flow changes, the EDGE CONTACT and quilt of condensed water and liquid collecting portion 74 It stops.The intersection of liquid collecting portion 74 and lower liquid hole 63 forms the water hole 81 of heat exchanger plates, the condensation of 74 edge of liquid collecting portion aggregation Water can flow into water hole 81, and the poly- fluid apertures 83 for finally converging to partition 57 is discharged.74 structure of liquid collecting portion in the first air duct 71 is conducive to Condensed water collects, and compressed air and condensed water can be efficiently separated.In other embodiments, the edge in liquid collecting portion 74 can Spiral yarn shaped to be arranged to, this marginal texture has better polywater effect.Further, strainer is set in water hole 81, When compressed air stream filter screen, the condensed water in air is easy to be tangled by strainer, and the separation for improving compressed air and condensed water is imitated Fruit.

Second air duct 72 has return air portion 75, and the gas flow front in the second air duct 72 is arranged in return air portion 75, returns The width in wind portion 75 forms heat exchanger plates less than 72 rest part of the second air duct, return air portion 75 and the intersection of lower liquid hole 63 Return air hole 82.In conjunction with shown in Figure 16 to Figure 18, compressed air flows through the laggard blasthole 81 in the first air duct 71, parting bead and lower liquid hole 63 It partially overlaps, gas is passed through from the intersection of parting bead and lower liquid hole 63, enters the second air duct 72 from return air hole 82.Second air duct 72 edges to connect with return air portion 75 are curve, are conducive to spread in the second air duct 72 from the gas that return air hole 82 flows into, increase Pressurize area of the stream of compressed air through plate shell 60.

Return air hole 82 in conjunction with shown in Figure 18, in order to further increase the heat transfer effect of compressed air, in adjacent heat exchanger plates Location dislocation, i.e., 75 position of return air portion on the air duct piece 70 of adjacent heat exchanger plates is different, the return air portion 75 of a certain piece of air duct piece 70 Close to 72 one side edge of the second air duct, then the return air portion 75 of adjacent air duct piece 70 is close to another side edge in the second air duct 72.This Sample air will not flow directly into the return air holes 82 of adjacent heat exchanger plates after flowing out from the first air duct 71 of a certain heat exchanger plates, and can only be from The return air hole 82 of the heat exchanger plates is flow back into the second air duct 72, it is ensured that the gas for flowing into heat exchanger plates has to flow through 71 He of the first air duct It could be flowed out from venthole 62 behind second air duct 72, improve the heat transfer effect of heat exchanger 41.

Medical-grade compressor provided in this embodiment has efficient refrigerating plant 40, can reduce rapidly the temperature of compressed air Degree makes steam liquefaction separation, and the compressed air that output is clean, dry is used for Medical Devices, easy to operate.
