PURPOSE:To improve weight balance by dividing a cooling water heat exchanger into a main and an auxiliary heat exchangers, and disposing the main heat exchanger on one side in the lateral direction of a body frame, and a lubricating oil heat exchanger and the auxiliary heat exchanger vertically on the other side. CONSTITUTION:A cooling water heat exchanger 1, interposed in a water cooling system Cw, is formed into the two-piece structure of a main heat exchanger 11, of large capacity and an auxiliary heat exchanger 12 of smaller capacity, and the main heat exchanger 11 is disposed on the front part let side of a body frame F, along the down tube 5 of the body frame F. The auxiliary heat exchanger 12 and a lubricating oil heat exchanger 2 are disposed vertically on the right side of the body frame F, along the down tube 5; and the main heat exchanger 11, and the lubricating oil heat exchanger 2 and auxiliary heat exchanger 12 are disposed in mutually parallel proximity, with the body frame interposed in between. This enables compact disposition, improves weight balance, attains low center-of-gravity, and above all improve the cooling efficiency of the lubricating oil heat exchanger 2. |
