[0012] Preferably, a plurality of mounting holes are provided on the fixing ring corresponding to the flange, and at least one baffle is fixed on the inner wall of the pipe cover.

[0013] Technical effects and advantages of the utility model:

[0014] In the utility model, the mixed gas enters from the air inlet pipe and is discharged from the air outlet pipe, and the mixed gas is cooled by heat conduction. The coolant is in direct contact with the pipeline. The baffle plate is set to reduce the flow rate of the mixed gas, increase the time the mixed gas stays in the serpentine pipe, and thus improve the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
