AI Technical Summary

Problems solved by technology

In the first example, since the front of the radiator 33 is provided with an oil cooler 34 and an intercooler 35 side by side, when cleaning the dust adhering to the front of the radiator 33, the oil cooler 34 and the intercooler 35 must be disassembled, which increases the unnecessary work time
In addition, since the radiator 50 and the intercooler 52 in the second example are integrated, sometimes only one side needs to be disassembled from the vehicle body for maintenance, and both sides must be disassembled, resulting in waste.
In the third example, since the oil cooler 64 can be tilted forward, although the front and upper part of the radiator 63 can be cleaned, it is difficult for the cleaning tool to penetrate into the lower part.
Furthermore, if the inclination is increased, it is difficult to improve due to the constraints of the body space.

Embodiment Construction

[0022] Below to Figure 1 to Figure 6 Embodiments of the cooling device for construction machines according to the present invention will be described.

[0023] First, with Figure 1 to Figure 5 The first embodiment will be described. figure 1 It is a front view of the cooling device of the first embodiment, figure 2 is the Z view of the graph, image 3 yes figure 1 the Y view. in addition, Figure 4 yes figure 2 the X view, Figure 5 is a perspective view of the fan guard.

[0024] Such as Figure 1 ~ Figure 4 As shown, the cooling device 10 is installed on the upstream side of the fan 26 on the engine 25, and the frame 1 with the opening 1a is provided on the ventilation path of the fan 26. In the opening 1 a of the frame 1 , a radiator 11 , an oil cooler 12 , and an aftercooler 13 are arranged in parallel, and their front surfaces are substantially on the same plane. Frame 1 is made up of upper and lower brackets 4,5 connected up and down between the left and...

Abstract

A cooling device for a construction machine allowing easy maintenances such as cleaning, inspection and repair of cooling apparatuses such as a radiator, an oil cooler and an after cooler, comprises a frame 1 forming an opening part 1a on an airflow route is provided upstream of a fan 26. The radiator 11A and the oil cooler 12, or the radiator 11 and the oil cooler 12 and the after cooler 13 are arranged on the opening part 1a of the frame 1 in parallel and the one of the radiator 11A and the oil cooler 12, or the radiator 11 and the oil cooler 12 and the after cooler 13 is detachably attached on the frame 1. A fan shroud 19 is attached on the frame 1. A part of the fan shroud 19 can be detachable.

Description

technical field [0001] The present invention relates to a cooling device for a construction machine. Background technique [0002] Construction machinery must have a radiator for cooling the engine cooling water and an oil cooler for cooling the working oil of the hydraulic unit. In recent years, in order to improve the efficiency of engine intake air and improve engine performance, an aftercooler is used to cool the compressed charge air. Several proposals have previously been made to improve the cooling efficiency and completeness and compactness of the installation space of these cooling devices. [0003] For example, as a first example, it is a cooling device for a construction machine disclosed in JP 11-350530 A, Figure 7 It is a layout diagram of the cooling device published in this gazette. Figure 7 Radiator 33 is arranged on the cooling device 30 in, is arranged on the front of the fan 32 driven by engine 31. An oil cooler 34 and an intercooler 35 are arranged in...
