Title
(EN) Cooling structure of construction machine
(ZH) 建筑机械的冷却构造
Abstract
(EN) The object of the invention is to increase soundproof performance of a cooling structure of a construction machine on an intake side without increasing the size of an intake chamber. The intake chamber (16) is formed in an engine room (12) on the intake side of a heat exchanger (15), and a first intake port (17) is formed in the upper surface part of the intake chamber (16). An independent duct (18) as a shielding member is installed in the intake chamber (16) so as to surround airtight the core surface (15a) of the heat exchanger (15) from the periphery and the inside of the intake chamber (16) can be partitioned into two chambers (16a) and (16b). A second intake port (23) is formed in the duct (18) to form the intake chamber (16) in a double duct structure so as to lead an air sucked from the first intake port (17) to the core surface (15a) of the heat exchanger through an intake passage bent in a roughly L-shape.

本发明的课题在于,不扩张吸气室且提高吸气侧的隔音性能。在发动机室(12)内的热交换器(15)的吸气侧形成吸气室(16),在该吸气室(16)的上表面部上设置第1吸气口(17)。在吸气室(16)内,以从周围气密地包围热交换器(15)的芯面(15a)并且将吸气室(16)内部分隔为两个室(16a、16b)的状态,设置作为屏蔽部件的独立的管道(18)。通过在该管道(18)上设置第2吸气口(23),使吸气室(16)为双层管道构造,使从第1吸气口(17)吸入的空气通过弯曲成大致L字形的吸气通路而将其导向热交换器芯面(15a)。
