[Industrial applications]

 The present invention relates to an air guide device particularly suitable for an intercooler for a turbo engine.

[0002]

[Prior art]

 For example, in a turbo engine intercooler for a diesel engine in a cab-over type truck, as shown in FIG. 7, an intercooler 52 is installed in front of a radiator 51, as shown in FIG. This is because it is intended to cool the intercooler 52 at the same time by placing it in front of the radiator 51.

In addition, for example, in Japanese Utility Model Laid-Open No. 57-80622 as well, for the same reason, as shown in FIG. 8, the aftercooler 61 is also provided in front of the radiator 62 in the vicinity thereof.

Another conventional technique related to this type of cooling and heat insulation is disclosed in Japanese Utility Model Laid-Open No. 56-36583. As shown in FIGS. 9 and 10, this is to improve the heat insulation of the cab 71 by providing an outside air introduction path 74 between the floor plate 72 and the underfloor plate 73 of the cab 71. Similarly, in order to improve the heat insulation from the operator's cab, as shown in FIGS. 11 and 12, the floor panel under the bed in the cab has a double structure, and the air between the floor panels 81 and 82 is doubled. A heat insulating chamber 83 is formed, and the air heat insulating chamber 83 is provided with an outside air outlet 84, which is disclosed in Japanese Utility Model Laid-Open No. 62-15684.

[Problems to be solved by the device]

 However, if an intercooler is installed in front of the radiator, the intercooler may deteriorate the cooling performance of the radiator. To prevent this, the radiator must be upsized, which is not preferable. This is especially a problem when mounted on a swirl chamber type diesel engine, which is advantageous for noise control and exhaust gas control. This is because the whirlpool type diesel engine does not have very good cooling performance.

Further, the above-mentioned related art in which the outside of the cab has a double structure to introduce outside air into the structure is not a direct solution to such a problem.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and aims to solve the problem by providing an intercooler air guide device capable of mounting an intercooler without impairing the cooling performance of the radiator. is there.

Therefore, in the present invention, as shown in FIG. 1, in a vehicle having a radiator 2 in front of the engine 1, an intercooler 3 is provided at a position behind the cab 4, and an air for introducing traveling air to the intercooler 3 is introduced. It is characterized in that the guide 5 is provided along the floor surface 6 of the cab 4.

[0009]

[Action]

 Since the intercooler 3 and the radiator 2 are separately arranged, the intercooler 3 and the radiator 2 are cooled by separate traveling winds, respectively, and the cooling performance of the radiator 2 does not deteriorate at all.

Moreover, since the intercooler 3 is provided behind the cab 4, there is no problem in the arrangement around the cab and the layout is easy. Also, the piping to the intercooler 3 can be relatively short.

Since the air guide 5 is provided rearward along the floor surface of the cab 4, the air guide 5 can be shared with the middle member which is a structural member of the cab 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a perspective view of a frame portion of a cab-over type vehicle, 11 is an engine, and 12 is a radiator. An intercooler 13 is fixed to a frame 15 by a bracket 14 behind the engine 11. Details of fixing the intercooler 13 are as shown in FIG. In the figure, 16 is a sending side pipe, and 17 is a return air pipe.

As shown in FIGS. 4 and 5, an air guide 19 for introducing traveling wind is provided along the floor surface of the cab 18 to the intercooler 13 located behind the cab 18. FIG. 6 shows a cross section of the air guide 19, which forms a running air introduction path together with the floor 20 of the cab 18.

The present embodiment is mounted on a vehicle as described above, and as is clear from FIGS. 2 and 4, an intercooler 13 is arranged behind the cab 18, and a traveling wind separate from the radiator 12 is used. Since it is cooled, it has a high cooling effect and does not affect the cooling performance of the radiator 12. Therefore, it can also be applied to swirl chamber diesel engines that do not have very good cooling performance.

Further, the delivery side pipe 16 and the return air side pipe 17 accompanying the installation of the intercooler 13 can be relatively short. Of course, it does not adversely affect the layout around the cab 18.

Further, the air guide 19 is formed in a closed surface shape by utilizing the middle member on the lower surface of the cab floor, and the middle member can be partially used, which is advantageous in layout.

The air guide may be an air guide 21 provided along the floor surface of the cab, as shown in FIGS.

[0018]

[Effect of device]

 According to this invention, since the intercooler is arranged separately from the radiator, the intercoolers are cooled by separate running winds and the cooling performance of the radiator does not deteriorate at all.

Moreover, since the intercooler is located behind the cab, there is no problem in the layout around the cab and the layout is easy. Also, the piping to the intercooler can be relatively short.

Further, since the air guide is provided rearward along the floor surface of the cab, it is possible to share this air guide with the middle member which is a structural member of the cab, which is advantageous in layout.
