CROSS REFERENCE

The present application claims the benefit under 35 U.S.C. § 119 of German Patent Application No. DE 102018202303.4 filed on Feb. 15, 2018, which is expressly incorporated herein by reference in its entirety.

BACKGROUND INFORMATION

The present invention relates to a sensor system for attaching a sensor set-up to a vehicle, and to a vehicle having this sensor system.

German Patent Application No. DE 101 60 935 A1 describes a motor vehicle cooling apparatus for electrical devices. In this context, at least one electrical device to be cooled is situated in the interior of a vehicle. The device includes a heat pipe, which connects the device thermally to the air-conditioning system of the vehicle.

German Patent Application No. DE 10 2010 064 343 A1 describes a method of cooling a module for a vehicle, as well as a corresponding cooling apparatus and a vehicle. In this context, the cooling apparatus includes a passive heat conductor and a heat sink in the region of the roof of the vehicle. The waste heat of the module is absorbed by the heat conductor and transported to the heat sink with the aid of the heat conductor.

SUMMARY

The present invention describes a sensor system for attaching a sensor set-up to a vehicle. The sensor set-up of the sensor system includes a housing and a sensor. In addition to the sensor set-up, the sensor system includes a connecting assembly capable of being mounted to the vehicle. The sensor set-up is fastened to the connecting assembly. In addition, the sensor system includes at least one heat pipe. The heat pipe connects the sensor set-up and the connecting assembly in a thermally conductive manner.

An advantage of an example sensor system in accordance with the present invention is that the sensor set-up may be adjusted by at least one degree of freedom with respect to the connecting assembly. Thus, after the sensor is attached, the position and/or the direction of the sensor may be changed, in order to adjust the sensing range of the sensor to the requirement.

Another advantage of an example sensor system in accordance with the present invention is that the heat of the sensor is conducted by at least one heat pipe to the connecting assembly and/or to the vehicle. Consequently, an overly high temperature of the sensor, which may result in damage to the sensor, is prevented.

According to an embodiment of the present invention, not only may the sensor be mounted to the vehicle so as to be adjustable by at least one degree of freedom, but also the heat of the sensor may simultaneously be conducted by at least one heat pipe to the connecting assembly and to the vehicle. Within the scope of the present invention, it has been recognized that in spite of its thermally conductive contact with the sensor set-up and with the connecting assembly, the heat pipe is sufficiently flexible to allow relative movement of these two set-ups with respect to each other.

The heat pipe is a component part for transporting heat from one location to another. The heat pipe may also be referred to as a thermally conductive pipe. The heat pipe is designed for a high heat-flux density, using a heat of vaporization of a medium; that is, large amounts of heat may be transported through the heat pipe on a small cross-sectional area.

Further refinements of the present invention are described herein.

It is preferably provided in accordance with the present invention that the sensor set-up be rotationally and/or slidably mounted to the connecting assembly. Because of this, the sensor set-up is rotatable and/or displaceable with respect to the stationary connecting assembly.

In particular, it is provided that the connecting assembly include at least one adjusting element for moving the sensor set-up. By adjusting the adjusting element, the sensor set-up may be adjusted rotatably and/or slidably. In addition, the sensor set-up may be held in the set position by the adjusting element.

The adjusting element preferably takes the form of an adjusting screw. The sensor set-up may be adjusted by screwing the adjusting screw in or out. In addition, the sensor set-up may be held by the adjusting screw, so that the sensor set-up may not move freely.

As an option, it is provided that the heat pipe have at least one curved region. The curved region is able to be bent in response to adjusting the sensor set-up. In this context, the heat pipe is advantageously positioned and bent in a suitable manner, so that it abuts the sensor set-up and/or the connecting assembly to produce as much contact surface as possible.

The heat pipe is preferably bent in an L-shaped manner. The L-shaped heat pipe allows two sides of the sensor set-up and the connecting assembly forming an angle with each other, to be connected thermally. The L-shaped heat pipe includes, in particular, two non-parallel arms, which are connected by the curved region.

In addition, the heat pipe may be bent in the shape of a U. The U-shaped heat pipe allows two opposite sides of the sensor set-up and the connecting assembly to be connected thermally. The U-shaped heat pipe includes, in particular, two parallel arms, which are connected by the curved region.

The heat pipe, in particular, the two arms of the U-shaped or L-shaped heat pipe, are situated preferably in a first plane. The sensor set-up is preferably movable about an axis of rotation with respect to the connecting assembly. This axis of rotation stands preferably vertically on the first plane. Due to this, a mechanical loading of the curved region of the heat pipe, which is as low as possible, is generated during adjustment.

It is preferably provided that the heat pipe abuts the housing and/or be situated in a groove of the housing, and/or be in a hole of the housing. If the heat pipe abuts the housing, then the mounting of the heat pipe is relatively simple. The heat pipe in the groove or in the hole produces a relatively greater contact surface between the heat pipe and the housing, as well as more effective protection of the heat pipe from mechanical effects.

The heat pipe preferably abuts the connecting assembly and/or is situated in a groove of the connecting assembly and/or is in a hole of the connecting assembly. If the heat pipe abuts the connecting assembly, then the mounting of the heat pipe is relatively simple. The heat pipe in the groove or in the hole produces a relatively greater contact surface between the heat pipe and the connecting assembly, as well as more effective protection of the heat pipe from mechanical influences.

The heat pipe contains, in particular, a hermetically encapsulated volume, preferably in the form of a tube. The volume of the heat pipe is filled, in particular, with a working medium, such as water or ammonia. In particular, the working medium of the heat pipe fills up a small part of the volume in the liquid state and a larger part in the vaporous state. The heat pipe includes, in particular, a vapor duct for the vaporous working medium of the heat pipe and a condensate duct for transporting the working medium back. After condensing, the working medium is transported back by gravity or capillary action. In this context, the heat pipe optionally includes a capillary structure.

The sensor preferably takes the form of an environmental monitoring sensor for monitoring a surrounding area of a vehicle. The environmental monitoring sensor is used for acquiring data about the surrounding area of the vehicle.

The environmental monitoring sensor optionally takes the form of radar, lidar, a camera, infrared sensor or ultrasonic sensor.

The sensor system may preferably include at least two of the described heat pipes. Preferably, at least two heat pipes are positioned in parallel with each other.

The present invention further includes a vehicle, preferably a road vehicle, including at least one sensor system described above. The sensor system allows flexible monitoring of the surrounding area of the vehicle. This information may be communicated to the driver via, e.g., an interface, so that the driving safety is increased. In addition, the information may be used by a driver assistance system.
