^II EXHAUST GAS LIQUID HEAT EXCHANGER ^II

2) Field of application ι The invention relates to a liquid heat exchanger, which can subsequently be easily inserted into the exhaust pipe in caravans, mobile homes, mobile or stationary sales booths that are already equipped with circulating air or radiant heating and whose exhaust gases are diverted via the roof or wall chimney can be.

3) Purpose:

With the "exhaust gas liquid heat exchanger" both domestic water and liquid can be heated for heating purposes without additional energy costs.

4) State of the art:

There is a wide variety of electric or gas-operated hot water devices for domestic hot water or to heat liquids.

of the technique:

Hot water devices of all conceivable variations are available especially for caravans the market.

However, "exhaust gas-liquid heat exchangers I ^{1" are excluded}

For all vehicles mentioned under (2) etc. there is not electrical energy everywhere available and is not possible everywhere due to the high connected load. For hot water devices that run on gas In addition to the high purchase price, they have their own burner need to have at their disposal and thus consume additional energy hot exhaust gases are released into the open unused.

The conclusion of the above statements is: Devices that produce hot domestic water must consume additional energy, the hot exhaust gases go unused into the open, without this additional energy being able to contribute to the indoor climate.

6) Task ^ The invention is based on the task for the area of application described under (2), hot service water or liquids for heating purposes, e.g. a "mobile underfloor heating" DE 3203428 A1, F 24 D, 19/02 too operate. It should be a device that can be used without difficult conversions, can be easily inserted into the existing exhaust pipe. This should be linked to the purchase price be lower than conventional devices, especially since there are no additional energy costs develop.

7) Solution ^ The object is thereby achieved according to the invention

solved that a pipe section of the same diameter like the exhaust pipe, which can be flexible or rigid, into the exhaust pipe is inserted by push-in sleeves or clamps. This pipe section is from a (Surrounded at the top and bottom of a closed cylinder from which the pipe section ends protrude. The medium to be heated is located in the cylinder. The hot exhaust gases flow through the piece of pipe, which is surrounded by the liquid hedium, and heat the same in the process fruf. On the upper and lower part of the cylinder there is a hole each with a connection for the flow and return. The cylinder can fcuch be divided into two chambers by an intermediate floor, but must then with each Two connections can be made so that domestic water and a frost-proof Medium can be heated for heating purposes

If sufficient electrical energy is available, the "exhaust gas / liquid heat exchanger" can also be equipped with • an electric heater. J) it is "exhaust gas-liquid heat exchanger" The feet are provided with insulation.

^The " ¹ ^ of ^the invention achievable advantages are in particular that: warm service water and / or liquids for heating purposes can be provided without additional costs.

the "exhaust gas-liquid heat exchanger" retrofitted in caravans, mobile homes, mobile or stationary sales stands, weekend or Hunting lodges and boats that are equipped with radiation or convection heating are easy to install. a device can be offered which is low in purchase price and does not cause any follow-up costs.

Due to its Eauart it has no mechanical parts, no operation required, and absolutely is maintenance-free.

Result of own research:

After reviewing the patent documents in Darmstadt, only one patent application became that of the utility model application comes close, under No. 25 30 219 F 24 B 9/00, but which has a different purpose serves, found.

9) Description_of

An embodiment of the invention is shown in the drawing and is in described in more detail below. Show it:

Fig. 1 an "exhaust gas-liquid heat exchanger"

Fig. 2 the representation of the "exhaust gas liquid heat exchanger" in half cut.

Pos. 1 the pipe section through which the exhaust gases flow will.

Pos. 2 the top and bottom closed cylinder that surrounds the pipe section.

Pos. 3 the medium to be heated.

Pos. 4 the insulation.

Pos. 5 the connections for flow and return.

Pos. 6 the intermediate floor for a second chamber.
