Abstract

In many cases, it is necessary to mount electric cables in the vicinity of hot components in a vehicle engine compartment. According to the present invention, an arrangement is used comprising an elongated channel in which the electric cables are enclosed and an adjacent elongated tubular channel in which a cooling air stream flows. One end of the air channel is connected to a fan cover and in operation a fan will draw air not only through a radiator but also create a low air pressure in the fan cover that will result in an air stream through the cooling channel. Thereby, the electric cables are cooled by the air stream in the adjacent cooling channel. Furthermore, the walls of the cable channel protect the electric cables from the heat radiation from hot components.

An arrangement for cooling of electric cables in a vehicle engine compartment

In many cases, it is necessary to mount electric cables in the vicinity of hot components in a vehicle engine compartment. Such components are, for example, exhaust manifolds and turbo aggregates. However, there is a risk that electric cables mounted in the vicinity of such components can be demaged by the heat from the components.  

According to the present invention, an arrangement is used comprising an elongated channel in which the electric cables are enclosed and an adjacent elongated tubular channel in which a cooling air stream flows. Thereby, the electric cables are cooled by the air stream in the adjacent cooling channel. Furthermore, the walls of the cable channel protect the electric cables from the heat radiation from hot components.

Fig. 1 and 2 show an embodiment of the invention. An internal  combustion engine 1 is mounted in a vehicle engine compartment. A radiator installation 2 is mounted in a front area of the vehicle. The radiator installation 2 comprises an intercooler 3 and a radiator 4. Behind the radiator 4, it is a fan cover 5 and a fan 6, which is sucking air through the intercooler 3, the radiator 4 and so on. A turbo aggregate 7 is mounted on the hot side of the internal combustion engine 1. A bundle of electric cables 8 is mounted such that they have an extension in the vicinity of the internal combustion engine 1. An arrangement 9 for protecting the electric cables 8 from the heat from the turbo aggregate 7 is arranged along the hot side of the internal combustion engine 1.

Fig. 2 shows a cross section view of the arrangement 9. The arrangement 9 includes a profile 9a forming a c...
