Description

Technical Field

[0001] This disclosure relates to a vehicle spoiler. Background Technology

[0002] It is known from US 2019 / 027818 A1 that the TCU is arranged in the cavity of the spoiler. Summary of the Invention

[0003] The purpose of this invention is to provide a vehicle spoiler that allows for improved functionality and availability of telematics systems.

[0004] This invention provides a vehicle spoiler comprising a body and electronic components, wherein the body includes a cavity in which the electronic components are disposed, wherein the spoiler includes an external recess, wherein the spoiler includes an external heat sink disposed in the external recess of the body, and wherein the external recess opens into the cavity. This spoiler is suitable for enhancing the thermal management of telematics systems because the electronic components, as part of the spoiler, can be effectively cooled.

[0005] Furthermore, the spoiler body includes an internal recess, and the spoiler includes an internal heat sink, wherein the internal heat sink is disposed within the internal recess of the body, and the internal recess opens into a cavity, wherein the cavity is disposed between the external recess and the internal recess. A second heat sink enhances the spoiler's cooling capacity.

[0006] Furthermore, the external heat sink is either part of the body's skin or is covered by the body's skin. This positioning of the external heat sink provides effective cooling because it can be cooled directly or almost directly by the airflow.

[0007] Furthermore, the main body includes a cooling channel structure, wherein an internal recess is arranged between the cavity and the intermediate section of the cooling channel structure, and wherein the cooling channel structure includes at least one inlet and at least one outlet. Cooling capacity is enhanced by the cooling channel structure. This means that cooling is more efficient.

[0008] Furthermore, the inlet and outlet are positioned on the spoiler in such a way that airflow is generated within the cooling channel structure by an airflow, wherein the inlet is located in the front region of the spoiler body, where an overpressure is generated by the airflow, and wherein the outlet is located in the rear region of the spoiler body, where the pressure is lower than the overpressure. This arrangement results in highly efficient cooling.

[0009] Furthermore, the inlet and outlet are positioned on the spoiler in such a way that airflow is generated within the cooling channel structure, with the outlet located in the front region of the spoiler body where suction is generated by the airflow, and the inlet located in the rear region of the spoiler body where air can be drawn in. This arrangement results in highly efficient cooling.

[0010] Furthermore, the spoiler includes a fan, which is arranged either within the cooling channel structure or external to the main body, at the outlet or inlet of the cooling channel structure. Where the fan is located external to the spoiler's main body, the fan includes a housing whose shape is aerodynamically designed and complementary to the main body. This arrangement allows for continued effective cooling when the vehicle is parked or during traffic jams. Additionally, the fan's location within the spoiler has the advantage that, since there is no direct connection between the spoiler and the vehicle interior, the fan will not be audible inside the vehicle.

[0011] Furthermore, the electronic component includes

[0012] - Antenna, or

[0013] -TCU, or

[0014] - Antenna and TCU, or

[0015] - Antenna and TCU, as well as additional electronic components, such as at least one amplifier,

[0016] In cases where electronic components include an antenna and a TCU, the antenna is housed in a cavity near an external heat sink, while the TCU is housed in a cavity near an internal heat sink. This structure ensures reliable cooling of the TCU.

[0017] Furthermore, it is specified that the at least one amplifier is arranged in a cavity, either near the TCU and near the internal heat sink, or near the antenna and near the external heat sink. This structure allows for effective cooling of most of the electronics necessary for telematics functions, especially the antenna amplifier.

[0018] According to another embodiment, a first cooling channel structure is positioned to cool the TCU, and at least one additional cooling channel structure is positioned to cool at least one antenna and / or at least one amplifier. This arrangement with multiple cooling channel structures makes cooling more efficient and allows the dimensions of each cooling channel structure to be designed according to the required cooling capacity.

[0019] According to the present invention, the TCU is an embedded system mounted on a vehicle that provides the vehicle with radio communication capabilities, such as access to the Internet.

[0020] According to the present invention, the electronic component includes at least one electronic unit, such as a TCU as a first electronic unit, an antenna as a second electronic unit, and an amplifier as an optional third electronic unit. Attached Figure Description

Therefore, the internal heat sink 222 is cooled by the surrounding air A flowing through the cooling channel structure 241.

[0037] Inlet 243 and outlet 244 are positioned on the body 202 of spoiler 201 in such a manner that airflow AS generates airflow AF in cooling channel structure 241, wherein inlet 243 is located in front region 245 of body 202 of spoiler 201, where overpressure P1 is generated by airflow AS. Outlet is located opposite inlet 243 in rear region 246 of body 202 of spoiler 201. Airflow AS and airflow AF flow in approximately the same direction, i.e., in the direction of airflow AS.
