Further, the end of described baffle a is connected with the box body wall over against water intake, and the other end of baffle a is connected with box body wall over against heat exchange area.
Further, the guide face of described baffle a and the angle between the box body wall are 10 ° ~ 80 °.
Further, with the water outlet of exhalant region over against corner be provided with baffle b.
Further, the end of described baffle b is connected with the box body wall over against water outlet, and the other end is connected with box body wall over against heat exchange area.
Further, the guide face of described baffle b and the angle between the box body wall are 10 ° ~ 80 °.
Further, described baffle a adopts the cabinet wall that is bolted to inhalant region, and perhaps baffle a and casing are one-body molded.
Further, described baffle b adopts the cabinet wall that is bolted to exhalant region, and perhaps baffle b casing is one-body molded.
Further, the guide face of described baffle a is for facing directly or curved surface; The guide face of described baffle b is for facing directly or curved surface.
Than prior art, the utility model arranges baffle a at inhalant region, when baffle a is passed through in water inlet, because the guide functions of baffle a is changed the direction of a stream of water, reduced the reverse resistance of current, flow resistance reduces, and flow velocity increases, improve heat exchange efficiency, and can reduce the fuel consumption of motor.
