As a further improvement on the present invention, cooling water inlet pipe extends substantially horizontally, thus more conducively current are along body
The rotation of inwall.
As a further improvement on the present invention, the link position of cooling water inlet pipe and condenser body is on gravity direction
Higher than inlet channel and the link position of condenser body, and it is connected to the lower half of condenser body.Therefore cooling water is from place
In the downstream of condenser air circulating direction fan and air heating apparatus farther out, the globule to disperse be not easy to be blown into fan and
In air heating apparatus.In addition, cooling water is more preferable closer to the position in air flow collection, heat exchange effect.
As a further improvement on the present invention, cooling water inlet pipe is so configured so that cooling water centrifuges along this body sidewall
Rotation, and the centrifugal rotation direction of air of the direction of rotation with entering body from inlet channel is identical.Therefore the resistance of air flow
Power is smaller, and cooling water is not easy to be blown afloat spray, and air and cooling water time of contact are more long, and heat exchange effect is more preferable.
