Fig. 3 is a schematic structural diagram of a heat exchanger 132 of the gas cooling device 100 according to an embodiment of the invention, please refer to fig. 3.
The heat exchanger 132 is used to cool down the gas entering the cooling chamber 130. Specifically, the heat exchanger 132 includes a condenser tube 138, and a refrigerant is disposed in the condenser tube 138. The condenser tube 138 is a copper tube or other metal tube, and has the characteristic of high heat transfer efficiency, and the condenser tube 138 may be formed by integrally forming a plurality of sections of U-shaped bent tubes and be disposed in the cover 131, or may be disposed in other shapes, which is not limited herein.

The driver 110 adopts a variable frequency motor, the blower 120 adopts a centrifugal fan, and the variable frequency motor is directly connected with the centrifugal fan. Because the variable frequency motor is adopted, the rotating speed of the motor can be adjusted, a speed reducing device can be omitted, the variable frequency motor directly drives the centrifugal fan to rotate, and the air inlet of the centrifugal fan is communicated with the cooling chamber 130. After the centrifugal fan rotates at a high speed, the cooling air in the cooling chamber 130 is sucked out and thrown out to the periphery by the centrifugal force. Then, the workpiece enters the heating chamber 140 through the first air port 143 or the second air port 145, and heat exchange with the workpiece in the heating chamber 140 is continued, so that the workpiece is refrigerated.
The gas cooling device 100 operates as follows:
A first refrigeration scenario, shown in fig. 1, is where the arrows represent the flow direction of the gas. The first cover 144 and the second cover 146 are opened, the first shutter 134 is opened, and the second shutter 136 is closed. A large amount of cooling gas enters the heating chamber 140 from the second tuyere 145 at the fastest speed, and the work piece completes the heat exchange. The gas heated after the heat exchange is discharged from the first tuyere 143, reaches the cooling chamber 130 through the first conduction port 133, exchanges temperature with the cooling water, and the cooling gas temperature is lowered. The cooled gas is sucked out by the centrifugal fan, discharged out of the cooling chamber 130, and again enters the heating chamber 140 through the second air port 145 to form circulated cooling.
A second refrigeration scenario, shown in fig. 2, is where the arrows represent the flow direction of the gas. The first cover 144 and the second cover 146 are opened, the second shutter 136 is opened, and the first shutter 134 is closed. A large amount of cooling gas enters the heating chamber 140 from the first tuyere 143 at the fastest speed, and the heat exchange with the work is completed. The gas heated after the heat exchange is discharged from the second tuyere 145, passes through the second conduction port 135 to the cooling chamber 130, exchanges temperature with the cooling water, and the cooling gas temperature is lowered. The cooled gas is sucked out by the centrifugal fan, discharged out of the cooling chamber 130, and again enters the heating chamber 140 through the first air port 143 to form circulated cooling.
By adopting the circulating cooling mode, the cooling water takes away heat rapidly, so that the workpiece is gas quenched in the shortest time, the gas quenching time of the workpiece is effectively shortened, and the product quality is ensured.
Fig. 4 is a schematic structural diagram of a vacuum gas quenching furnace 200 according to an embodiment of the invention, please refer to fig. 4.
The vacuum gas quenching furnace 200 provided in this embodiment includes a furnace body 210 and the gas cooling device 100 described above, where the gas cooling device 100 is installed in the furnace body 210. A sealed space is formed in the furnace body 210, so that the heat treatment processes such as heating, gas quenching (cooling) and the like of the workpiece are conveniently completed.
In summary, the gas cooling device 100 and the vacuum gas quenching furnace 200 provided by the invention have the following advantages:
The present invention provides a gas cooling apparatus 100 and a vacuum quenching furnace 200, which are provided with a driver 110, a blower 120, a cooling chamber 130 and a heating chamber 140. By changing the state of the first baffle 134 and the second baffle 136 to change the direction of the air flow, cooling of the workpiece can be achieved through different air flow paths. The forced hot gas is first cooled by heat exchanger 132, exhausted by a centrifugal fan, and recirculated back into heating chamber 140 for circulating refrigeration to the workpiece to effect the gas quenching process. The gas cooling device 100 and the vacuum gas quenching furnace 200 are simple in structure and flexible in temperature control, heat is taken away rapidly through cooling water, a workpiece is gas quenched in the shortest time, the gas quenching time of the workpiece is effectively shortened, and the product quality is ensured.
