Abstract
(EN)

[PROBLEMS] To increase soundproof performance of a cooling structure of a construction machine on an intake side without increasing the size of an intake chamber. [MEANS FOR SOLVING PROBLEMS] 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.

(KO) 본 발명의 과제는 흡기실을 확장하지 않고, 또한 흡기측의 방음 성능을 향상시키는 것이다. 엔진룸(12) 내에 있어서의 열교환기(15)의 흡기측에 흡기실(16)을 형성하고, 이 흡기실(16)의 상면부에 제1 흡기구(17)를 형성한다. 흡기실(16)에는, 차폐 부재로서의 독립된 덕트(18)를, 열교환기(15)의 코어면(15a)을 주위로부터 기밀하게 둘러싸는 동시에, 흡기실(16) 내를 2실(16a, 16b)로 구획하는 상태로 설치한다. 이 덕트(18)에 제2 흡기구(23)를 형성함으로써, 흡기실(16)을 이중 덕트 구조로 하고, 제1 흡기구(17)로부터 흡입된 공기를 대략 L자형으로 굴절된 흡기 통로를 통해 열교환기 코어면(15a)으로 유도하도록 구성했다.
