Abstract: A roof assembly for forming a vehicle roof on a motor vehicle, the roof assembly has a panel component which forms at least sections of a roof cladding of the vehicle roof, the roof cladding acting as an outer sealing surface, and a roof opening system having a lid part which is configured to selectively open or close a roof opening provided in the panel component, and at least one electric and/or electronic and/or electromagnetic component and an air conditioner, via which waste heat released by the electronic component and/or heat introduced from outside are able to be dissipated, wherein the roof opening system has at least one water gutter via which at least one cooling channel of the air conditioner is formed, the waste heat of the component and/or the heat introduced from outside being able to be dissipated from the roof assembly via cooling channel.

Abstract: A heat exchanger for transferring heat between a coolant and refrigerant, the heat exchanger comprising a heating device for heating the refrigerant and the coolant, comprises a bottom wall forming an end-face end of a stack of at least two flow volumes through which the refrigerant or coolant flows, a first flow volume for the refrigerant to flow through, which first flow volume is adjacent to the bottom wall and is connected to a first fluid inlet and to a first fluid outlet, which are configured to produce a connection to a refrigerant circuit, the first flow volume additionally being defined by a first partition opposite the bottom wall, and a second flow volume for the coolant to flow through, which second flow volume is adjacent to the first partition and opposite the first flow volume and is connected to a second fluid inlet and to a second fluid outlet.

Abstract: A sensor module for a motor vehicle, which has a carrier element, a see-through area, an environment sensor, which can capture a vehicle environment through the see-through area and which is adjustable relative to the carrier element, and an air-conditioning device. The air-conditioning device has a fan, which is arranged on the carrier element and is aimed at an inflow area of the environment sensor to air-condition the environment sensor.

Abstract: A sensor module for a motor vehicle may have a see-through area, an environmental sensor, which can detect the vehicle surroundings through the see-through area, and a climate control device (28) for the climate control of the environmental sensor, wherein the climate control device has a cooling device having a contact element for in particular thermally contacting and cooling the environmental sensor and a heating device having at least one heating element, wherein the at least one heating element is arranged at the contact element or is integrated in the contact element.

Abstract: A roof for a motor vehicle, in particular for a passenger car, having a roof skin which is disposed above a roof substructure and having a sensor system which has at least one sensor module having at least one environment sensor for detecting a vehicle environment. The roof has a cooling device for the sensor module, said cooling device having a compressed-air device by which compressed air is applied to the sensor module.
