PURPOSE:To enhance cooling efficiency, by respectively connecting the inflow port and the outflow port opened to the outside of a chemical agent tank to the hydraulic circuit of a pest control machine. CONSTITUTION:Both end parts of a heat exchanger 21 are respectively connected and fixed to opening parts of the inflow port 25 and the outflow port 26, which are pierced through a flange 24 secured by bolts 23 through packings 22', inside a chemical agent tank 1 so as to close orifices 22 provided to the side wall of said chemical agent tank 1 by drilling. The inflow port 25 and the outflow port 26 are also opened to the outside of the chemical agent tank 1 to form an inflow opening port 25a and outflow opening 26a and both openings 25a, 26a are respectively connected to oil motors 18, 19 and an oil tank 16 by pipelines 27, 28.
