Kind Code:
B2
Abstract:
PURPOSE:To simplify a heat insulating construction and improve soundproof performance by partitioning an upper room into two rooms and arranging a heat exchanger and an exhaust silencer in one room and a radiator in the other room, in a package device in which an engine and a working machine are arranged on the lower part of the package. CONSTITUTION:In a package C, a lower room in which an engine E and a working machine 9 such as a generator are arranged, is built as a soundproof room A, and sound insulating material is stuck inside of this soundproof room A and at upper part of this room A a ventilative fan 11 having small bore diameter and small capacity is provided. By actuation of this ventilative fan 11, fresh air is introduced into the soundproof room A from an intake gallery 16 which intakes cooling air of an upper radiator room B through a duct constructed with interior of a control board room 14. And an upper room over the soundproof room A is partitioned into the radiator room B and a heat exchanger room D with a partition wall 18, a radiator R is in the room B, and an exhaust gas heat exchanger 2, a water/water heat exchanger 8, and an exhaust silencer 3 are respectively in the room D arranged and provided.
