4 shows a side view of the carrier with which the external unit can be attached to a vehicle.

The invention relates to a lockable external unit 2 by means of a first carrier 3 and a second carrier 4 , which is releasably connectable to the first carrier, on a vehicle (car, truck, motorcycle, boat, ect.) Or trailer detachably connectable. The second unit 2 is detachable with a first unit 1 connected, which comprises at least one heat exchanger and / or a thermocouple. The first unit 1 is with the exhaust system 14 and / or another quickly heated part of the vehicle thermally conductively connected, whereby the first unit 1 is heated by the waste heat of the internal combustion engine.

In the second, external unit 2 Various energy (eg electricity, gas or fuel) powered devices can be installed, such as a water heater, a refrigerator 8th , a gas stove 7 , a flush / shower device 6 , a sink 15 , a toilet (similar to patent EP 0 812 732 A1 . GB 1308825 ). Furthermore, the second, external unit 2 be provided with various supply and storage elements, such as a gas cylinder and / or a gas cartridge 10 , a water reservoir 9 and a battery with / without voltage converter or power generator and / or solar system 11 , Because the second, external unit 2 separably connected to the vehicle and includes various power supply modules, the second, external unit 2 be operated independently of the vehicle.

The Collectors of the solar system can e.g. on the outside the external unit can be mounted.

For energy saving reasons, it is intended to use the waste heat generated during operation of the vehicle. For this purpose, at one, during operation of the vehicle particularly strong and quickly heated, vehicle part, such as the exhaust system 14 , a heat exchanger 1 installed thermally conductive. The heat exchanger 1 is by means of a heat carrier line 16 , For example, a flexible water pipe, and a heat transfer circulating device 5 , For example, a water circulation pump, with a heat carrier storage 17 , For example, a water storage operatively connected, in / on the vehicle and in the second, external unit 2 can be installed.

The heat exchanger is divisible to ensure easy mounting on the exhaust system. In order to ensure the largest possible contact surface with the exhaust system, the contact surface of the heat exchanger is adapted to the shape of the exhaust system. The heat exchanger consists of two half shells, which are placed around the exhaust pipe and fastened together.

By a in the hot water supply 16 installed remotely controllable distribution valve 12 The water is optionally through the hot water tank 17 directed, so that by circulating through the heat exchanger / water storage circuit, the water is heated or the water directly to the flush / shower device 6 directed.

Another remotely controllable distributor valve 13 in the supply lines to the flush / shower device 6 controls the water supply either directly from the heat exchanger 1 or from the water reservoir 17 , Via a suction pump 18 is the operating pressure of the flushing / showering device 6 regulated.

The flush / shower device 6 may contain a mixer to mix by mixing hot and cold water (eg from water storage 9 ) to set the desired mixing temperature.

The energy to operate the refrigerator 8th can also be obtained from the waste heat of the internal combustion engine. For this purpose, the heating element of the refrigerator is thermally conductive with the heat-carrying vehicle part, for example, the exhaust system 14 connected and installed the cooling element of the refrigerator in a cooler area of the vehicle, preferably in such a way that the cooling element is exposed to the wind, for example, in the outer region of the second, external unit 2 or near the vehicle radiator grill slots. A temperature switch and / or a voltage monitor on the thermocouple regulates the supply of the refrigerator via the thermocouple and / or the electrical system and / or a solar system or via gas, so that an optimal power supply of the refrigerator or other connected consumers is guaranteed.

To generate electricity, the Seebeck effect can be exploited. For this purpose, a thermocouple on the exhaust system 14 or be installed on any other heat-carrying element (see patent DE 4118979 ). The thermocouple consists of a heated and a cooled element. The temperature difference essentially determines the achievable voltage generated by the thermocouple. Preferably, the cooled part should be installed in the headwind at the coolest point possible, for example, near the vehicle radiator grill slots.

The carrier 2 is attached to the vehicle under the trunk. The load T1, eg the second, external unit 2 is about the carrier 3 & 4 distributed to the train stops T2. The tension holders at the draw points T2 receive the entire load transmitted via the lever arm a. The carrier 3 & 4 distributes the tensile load at the Zughaltepunkten T2 via the lever arm b on the pressure surface of the. Breakpoints T3.

The carrier 3 & 4 passes under the bumper so that the bumper does not need to be modified when mounting the carrier. The carrier is divisible, so that the carrier half can be removed on the load side in a few touches without removing the entire carrier from the vehicle. Preferably, the carrier is separated by a plug / screw connection below the bump days to ensure easy handling. Furthermore, such a direct view of the mounted carrier half is avoided, so that the optics of the vehicle is not disturbed.

by virtue of the construction of the carrier Is it possible, the carrier to any vehicle regardless of pre-installed attachment points assemble. For this purpose, only at least four anchoring points necessary: two breakpoints T2 in the rear of the vehicle and two breakpoints T3 towards the rear axle of the vehicle. Preferably, the distance keep the holding points T2 and T3 as large as possible, so that the Lever arm b as long as possible is. Furthermore, the lever arm a should be kept as short as possible so that the ratio a / b as small as possible becomes. For fixing to the pressure points T3 can be found on the vehicle carrier spars conventional Vehicles i.a. enough Holes, so there is no need mounting holes to create. To fix the carrier are thus only two more Drilling through the boot floor panel needed to the drawbar T2 too Fasten.
