| 摘要 |
The present invention discloses a heat exchanger tube for a heating system, which is suitable for any kinds of heating systems mounted in doors. The heat exchanger tube comprises a tube body, in which a plurality of lobes are formed on an outside surface of the tube body around the peripheral of the tube body and a plurality of ribs are formed on an outside surface of the tube body along the length of the tube body. Each of the ribs is inclined with respect to the longitude axis of the tube body by an angle of about 15 degree. The advantages of the present invention are in that: 1. the ribs could increase the heat exchanging surface; 2. the lobes could increase the heat radiating surface; and 3. as the heat exchanger tube is made of aluminum or aluminum alloy, the heating medium would not be polluted by rust generated in iron tubes.
