    • A cooling unit is provided for use with a cooling system of an internal combustion engine. The cooling system includes an air-cooled radiator to reject heat from a coolant of the internal combustion engine. The cooling unit comprises an air-cooled heat exchanger to reject heat from another medium to an air flow, an air receiver and at least one releasable clamp. The heat exchanger includes an inlet for the air flow, an outlet for the air flow, and an outer perimeter extending between the inlet and the outlet. The air receiver is connectable to the radiator and surrounds the outer perimeter of the heat exchanger. The air receiver includes an inlet end for the air flows, an outlet end for the air flow, and an air duct extending between the inlet end and the outlet end to direct the air flow from the outlet of the heat exchanger to the outlet end of the air receiver. The inlet end and the inlet are substantially coplanar. The clamp is engaged with the air receiver to tighten the air receiver against the heat exchanger.
    • 提供了一种与内燃机的冷却系统一起使用的冷却单元。 该冷却系统包括一个风冷散热器,以排除内燃机冷却剂的热量。 冷却单元包括一个空气冷却的热交换器,用于将来自另一介质的热量排除到空气流,空气接收器和至少一个可释放夹具。 热交换器包括用于空气流的入口,用于空气流的出口以及在入口和出口之间延伸的外周边。 空气接收器可连接到散热器并且围绕热交换器的外周。 空气接收器包括用于空气流的入口端,用于空气流的出口端,以及在入口端和出口端之间延伸的空气管道,以将空气流从热交换器的出口引导到出口端 空气接收器。 入口端和入口基本上共面。 夹具与空气接收器接合,以将空气接收器紧固在热交换器上。

    • An engine cooling air passage for construction equipment, which is capable of reducing noise released from a cooling air exhaust port with back pressure of cooling air remaining low and making an engine room compact, is provided. To this end, in the engine cooling passage, a fan air diversion passage (53) of a predetermined length, which has a fan air diversion opening (53a) located near an outer periphery portion of a cooling fan (16) and taking in a cooling air blown by the cooling fan (16), at one end side, and an opening (53b) located near a lateral end portion of a counterweight (61) and discharging the cooling air taken in to an outside, at the other end side, is formed either in a front portion of or in front of the counterweight (61).
    • 提供一种用于施工设备的发动机冷却空气通道,其能够降低冷却空气排出口的噪音,并且使冷却空气的背压保持低压并使发动机室紧凑。 为此,在发动机冷却通道中,具有预定长度的风扇空气引导通道(53),其具有位于冷却风扇(16)的外周部附近的风扇空气分配开口(53a) 在一端侧由冷却风扇(16)吹出的冷却空气和位于配重(61)的侧端部附近的开口(53b),并且将另一端侧的冷却风排出到外部 形成在配重(61)的前部或前方。
