Description:TECHNICAL FIELD
[001]
The present subject matter relates to a cooling system of a vehicle, more particularly, a configuration of a heat sink assembly on a frame assembly on a vehicle.
BACKGROUND 5
[002]
In general, a conventional vehicle comprises of a plurality of electrical and electronic components for regulating one or more vehicle functions. These electrical and electronic components are conventionally composed of a plurality of integrated circuits.
[003]
In general, plurality of integrated circuits comprises of IGBTs (insulated-10 gate bipolar transistor) and MOSFETs (metal-oxide-semiconductor field-effect transistor) which are conventionally used for regulating the electronic component based on a power supply provided by a battery. Due to the continuous operation of the electronic components, the IGBTs and MOSFETs heats up quickly and thereby reduces the overall efficiency of the electronic components. 15
[004]
In general, if effective heat dissipation from the plurality of electronic ??????????????????????????????????????????????????????????????????????????????????????????ignition of the electronic components. In order to prevent overheating and ignition of the electronic components, conventionally a plurality of cooling fans are used to dissipate the heat from the plurality of electronic components to the external atmosphere. 20
[005]
In general, each of the plurality of electronic components is provided with a corresponding cooling fan for heat dissipation. However, this configuration of providing a cooling fan with each of the plurality of electronic components makes the electronic components bulky and increases overall part count of the vehicle.
[006]
Furthermore, conventionally the packaging of the plurality of electronic 25 components with a corresponding cooling fan is difficult due to limited space in a vehicle, especially a two wheeled vehicle. Furthermore, the packaging of the cooling fan requires additional mounting brackets which in turn increases the overall part count and the overall weight of the vehicle.
[007]
Moreover, the packaging of the electronic components in the vehicle 30 layout is restricted due to disposition of the cooling fans in proximity to the external
3
environment
. This in turn decreases flexibility of packaging the electronic components in the vehicle and in turn reduces vehicle modularity.
[008]
Additionally, the conventional configuration of the electronic components coupled to a cooling fan increases the overall assembly time of the vehicle.
[009]
Hence, it is preferred to have a vehicle cooling system for cooling the 5 plurality of electronic components in the vehicle without increasing the part count and without changing the packaging layout of the vehicle.
