A heat exchange unit suitable for combination with a propeller fan comprises at least one pipe for coolant having porous passages for coolant inside thereof, said pipe being either spirally wound or one of a plurality of substantially circular pipes which are coaxially arranged. An inlet header are and an outlet header respectively connected to the inlet or the outlet of the pipe for coolant. At least one corrugated fin is interposed in a space formed between the adjacent pipes or portions of the spirally wound pipe. The heat exchanger is provided with a space at the central portion, and a fan motor is positioned in the central space of the heat exchanger. A propeller fan is fitted to the rotary shaft of the fan motor to feed air to the heat exchanger.

DETAILED DESCRIPTION The foregoing and the other object of the present invention have been attained by providing a heat exchanger unit suitable for combination with a propeller fan comprising (a) at least one pipe for coolant having porous passages for coolant inside thereof, the pipe being spirally wound or composed of a plurality of substantially circular members which are coaxially arranged; (b) an inlet header connected to the inlet of the pipe; (c) an outlet header connected to the outlet of the pipe; and (d) at least one corrugated fin interposed in a space formed between adjacent pipes or portions of the pipe.
In this construction, the heat exchanger is formed by the pipe for coolant, the inlet and outlet headers, and the corrugated fin.
The heat exchanger is provided with a space at the central portion, and a fan motor is positioned in the central space of the heat exchanger.
A propeller fan is fitted to the rotary shaft of the fan motor to feed air to the heat exchanger.
