Abstract

The present solution relates to a cooling arrangement and method for controlling a cooling arrangement of a vehicle. The cooling arrangement comprises a cooling package 1, e.g. radiator for cooling engine coolant. The cooling arrangement comprises a mechanically or hydraulically operated first fan unit 2 and an electrically operated second fan unit 3. The first and second fan units 2, 3 are arranged in connection to the cooling package 1 so that air A may be provided to the cooling package 1. The cooling arrangement may be controlled based on current situation during vehicle operation so that the first fan unit 2 and/or the second fan unit 3 are operated.

COOLING ARRANGEMENT AND METHOD FOR CONTROLLING COOLING ARRANGEMENT

ABSTRACT

The present solution relates to a cooling arrangement and method for controlling a cooling arrangement of a vehicle. The cooling arrangement comprises a cooling package 1, e.g. radiator for cooling engine coolant. The cooling arrangement comprises a mechanically or hydraulically operated first fan unit 2 and an electrically operated second fan unit 3. The first and second fan units 2, 3 are arranged in connection to the cooling package 1 so that air A may be provided to the cooling package 1. The cooling arrangement may be controlled based on current situation during vehicle operation so that the first fan unit 2 and/or the second fan unit 3 are operated.

BACKGROUND ART

Commercial vehicles usually have a cooling arrangement with a cooling package and mechanically or hydraulically operated fans for providing air cooling, i.e. mechanical or hydraulic fans. Sometimes such vehicles have an electrically operated fan, i.e. an electrical fan. Generally the electrical fan does not have enough cooling capacity to be used in heavier applications. For example a city bus with gas fuel is considered not to be suitable for electrical fans.

TECHNICAL SOLUTION

The present solution relates to a cooling arrangement and a method for controlling the cooling arrangement.

Fig. 1 below illustrates such a cooling arrangement for a vehicle according to an aspect of the present solution.

The vehicle may be any suitable vehicle such as a commercial vehicle, in the shape of a truck or a bus.

The cooling arrangement according to the aspect of the present solution illustrated in fig. 1 comprises a cooling package 1. The cooling package may be any suitable cooling package involving heat exchange associated with a fan arrangement configured to force air in connection to the cooling package. Thus, the cooling package may be any suitable cooling package where cooling by means of a fan arrangement, i.e. one or more fan units, configured to provide air A for cooling is required.

The cooling package 1 may comprise a radiator, e.g. an engine coolant radiator for cooling engine coolant, air being configured to be forced through the radiator by means of operating the fan arrangement. The cooling package 1 may comprise a so called Charge Air Cooler (CAC) configured to cool charged air before it enters the engine of the vehicle. The cooling package 1 may comprise an oil cooler configured to use engine oil as coolant, air being configured to be forced through the oil cooler by means of operating the fan arrangement.

The cooling arrangement according to the aspect of the present solution illustrated in fig. 1 comprises a fan arrangement 2, 3. The fan arrangement according to the aspect illustrated in fig. 1 comprises a first fan unit 2 arranged downstream of the cooling package 1 and a second fan unit 3 arranged upstream of the cooling package 1.

The first fan unit 2 is according to an aspect of the present sol...
