The top plate has an outlet hole opposite to the inlet hole. In the air inlet, a plurality of air deflectors are arranged around the inlet hole to guide the airflow from the air inlet to the air outlet. The plurality of air deflectors are spaced apart from the side wall to form an air outlet between the adjacent air deflectors. The workpiece cooling device comprises a fan and an air guiding device, the fan has an air outlet, the air guiding device comprises a bottom plate, a side wall protruding from the outer edge 200930474 of the bottom plate and a top plate, and the bottom plate has an inlet hole The top plate is opposite to the inlet hole and has an outlet hole. One side of the side wall is provided with an air inlet. The air inlet plate is spaced around the inlet hole. The plurality of air deflectors are arranged to guide the airflow from the air inlet to the outlet hole. Separating from the side wall and forming an air outlet between two adjacent air deflectors, the air inlet of the air guiding device communicates with the air outlet of the fan. Compared with the prior art, the air outlet of the workpiece cooling device surrounds the high temperature profile, and the cooling is uniform, and the profile is not deformed. [Embodiment] The structure of the air guiding device and the workpiece cooling device using the air guiding device will be further described below with reference to the drawings. As shown in Fig. 1, the workpiece cooling device 1 includes an air guiding device 2, a fan 3, and an atomizing device 4. The blower 3 supplies airflow, and the air outlet 31 of the blower 3 and the air guiding device 2 are connected by a windshield 5, or the air outlet 31 of the blower 3 and the air guiding device 2 are directly connected. The workpiece cooling unit can be used to cool high temperature profiles formed by warping, as well as to cool other machined workpieces. Referring to Figures 2, 3, and 4, the air guiding device 2 has an annular structure, including a bottom plate 21, a side wall 22 formed from the outer edge of the bottom plate 21, and a top plate 23 symmetrical with the bottom plate 21, The inner cavity is annular. A circular inlet hole 211 is defined in the bottom plate 21, and an air inlet 221 is defined in one side of the side wall 22. The top plate 23 defines an outlet hole 231 corresponding to the inlet hole 211. The inlet hole 211 is adjacent to the discharge port 61 of the extruder 6, and the high-temperature profile (not shown) processed by the extruder 6 can pass through the inlet hole 211 and the outlet hole 231 of the air guiding device 2 in succession. The air inlet 221 is directly connected to the air outlet 31 of the fan 3; or is connected to the air outlet 31 of the fan 3 through the hood 200930474 5 , the ice near the discharge port μ of the extruder 6 is high, and the wind hood 5 can realize the fan 3 away from the discharge port 61 of the extruder 6, cold air is introduced to enhance the cooling effect. A hollow annular projection f 212 is formed on the outer edge of the inlet hole 211 from the bottom plate 21, and the top surface 2123 of the annular projection 212 is a toroidal surface. A plurality of airflows are provided around the annular collar 212 to guide the airflow from the air inlet to the air outlet 24 and a wind deflector 25. The air deflector 24 is spaced apart from the side walls 22, 〇, respectively. The wind deflector 25 is located on one side opposite to the air inlet 221, and the side wall? Eight, 22 connections are separated from the top plate 23, and (10) of the air guiding device 2 is the first flow path 26 and the second flow path 27. A plurality of air deflectors 24 are circumferentially distributed around the annular boss 212 with the wind deflector 25 as a symmetry plane. An air outlet 29 is opened/formed between the adjacent t 〜 , between the air panels 24 , between the wind deflector 25 and the air deflector 24 adjacent thereto. The air deflector 2 can also be respectively connected to the top of the air. The air machine direction is as shown in Fig. 3. The air flow enters the air guide from the air inlet 22 Under the guidance of the wind deflector 24, a part of the airflow flows from the air outlet 29 in the radial direction to the 屮a ^ a - the outlet 231', and the other part of the airflow moves along the first flow passage 26 and the brother-27 in the circumferential direction, respectively. After the wind plate 25, it finally flows radially from the air outlet D 90 Ά AI , 29 sen to the exit hole 231. In order to make the air outlets at each air outlet 29 roughly the same: Temple ' along the air inlet 221 to the windshield In the direction of 24, the angle between the wind guides and the wind deflectors 25 gradually becomes smaller, and the length of each wind deflector 24 gradually becomes longer. Each air outlet 29 surrounds the entrance hole 2Π, and the air flow is scooped to the entire outer surface of the high temperature profile, so that the high temperature profile is: each = 200930474 airflow may flow into the hole 211, and the inlet hole 211 and the extruder 6 discharge The port 61 is adjacent to each other, and the temperature is high and the heat is not easily dissipated. Therefore, it is desirable to prevent the airflow from flowing into the hole 211. The top surface 2123 of the annular boss 212 is a toroidal surface which is inclined by the inlet hole 211 toward the hole 231. The top surface 2123 has an air guiding effect so that the air flow flows as far as possible to the exit hole 231 to avoid hot air circulation. In order to enhance the air guiding effect, an annular recessed table 232 can be formed to protrude downwardly along the outer edge of the outlet hole 231. The bottom surface 2323 of the annular recessed platform 232 is a ring inclined by the inlet hole 211 toward the outlet hole 231. surface. ❹ Referring to FIG. 5 together, the atomizing device 4 includes an air inlet port 41 for external high pressure gas, a gas flow regulating valve 42 for controlling air flow, a water inlet port 43, a water flow regulating valve 44 for controlling water flow, a mixing chamber 45, and a nozzle. 47. One end of the mixing chamber 45 is connected to the inlet port 41 via the damper valve 42, and the other end is connected to the nozzle 47. The cross-sectional area of the mixing chamber 45 is smaller than the cross-sectional area of the nozzle 47. A water outlet hole 48 is formed in the wall of the mixing chamber 45, and the water outlet hole 48 is connected to the water inlet port 43 via the water flow regulating valve 44. At the air inlet 221 of the air guiding device 2, an interface is provided. The nozzle 47 of the atomizing device 4 is connected to the interface 28. When the air flow regulating valve 42 and the water flow regulating valve 44 are opened, the high pressure gas enters the mixing chamber 45 at a high speed through the air inlet port 41 and the air flow regulating valve 44, and the high pressure gas flow rate is fast, so that a high pressure gas is generated between the high pressure gas and the wall of the mixing chamber 45. Pressurized, the liquid is sucked from the water outlet hole 48 into the mixing chamber 45 by the negative pressure, and is decomposed into fine liquid beads by the high-speed airflow to form a water mist, and enters the air inlet 221' of the air guiding device 2 via the nozzle 47 and the interface 28. Each of the air outlets 29 of the air unit 2 is hooked onto the warm profile. The temperature of the high-temperature profile is often above five hundred degrees, the water mist will become a gas, and the vaporization process of the water mist absorbs a large amount of heat, which accelerates the cooling rate of the high temperature of 200930474. In order to synchronize the water mist spraying process with the extrusion manufacturing process, the atomizing device 4 further includes a set of electromagnetic widths 46 respectively connected in series with the control switches (not shown) of the extruder 6, respectively controlling the water inlet 43 and The switch shape of the air inlet 41. When the control switch is turned on, the extruder 6 works, the water inlet 43 and the air inlet 41 are controlled by the electromagnetic valve 46, and the atomizing device 4 sprays water mist; when the control switch is turned off, the extruder 6 stops working, The solenoid valve 46 controls the water inlet 43 and the air inlet 41 to be closed, and the atomizing device 4 does not spray water mist. If the atomizing device 4 is interlocked with the extruder 6, the water is sprayed when the extruder 6 is in operation. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law.
