Definitions
- the invention relates to a heat exchanger, in particular for use in absorption refrigeration systems suitable is.
- Heat exchangers of known design for absorption refrigeration systems consist of horizontal Tube bundles that are rolled or welded into tube sheets on both sides. Such Execution is z. B. described in US 5 463 880 A. In these embodiments it is problematic to compensate for the differences in length caused by thermal expansion. In addition, it is relatively expensive to distribute the solution evenly to ensure the tube bundle. This requires trickle trays with a variety of holes and other spray devices, such as. B. according to US 5 463 880 A, over the entire Pipe bundles are distributed, which means a high level of construction and maintenance The openings have been cleaned.
- the object of the invention is therefore to find a solution that allows, if possible to arrange a large number of pipe spirals in a small space and yet a simple one Allow assembly.
- the object is achieved by the features of the claim, by arrangement the collecting and distribution pipes on the outer circumference of the spiral, the pipe spiral on the outside Manifold begins spiraling inward, reverses near the center and in the radial gaps of the spiral led out again in opposite directions and opens into the collecting tube. That presupposes that the radial distance between the spiral turns is slightly larger than the pipe diameter.
- the spiral can be made from two symmetrical parts. These single spirals are inserted into each other in mirror image and in the middle by a suitable piece of pipe connected with each other.
- the overall height is minimized by arranging them vertically one below the other Spirals with their ends leading outwards alternately from left and right can be integrated into a distributor or manifold.
- the same effect is achieved through the Separation of collecting and distribution pipes into several, but at least two individual pipes achieved.
- the spiral ends leading outwards are alternately divided into different and manifolds integrated.
- Fig. 1 shows how a tube spiral 2 housed in a container 1 and with the ends in a manifold 4 and a manifold 3 is integrated.
- 1 begins the first Pipe spiral 2 in the distribution pipe 3 and ends in the same plane in the collecting pipe 4.
- the second Pipe spiral 5 is arranged in mirror image and begins according to FIG. 2 in the collecting pipe 4 and ends in the distributor pipe 3. From FIG. 3 it can be seen how through the mutual integration of the pipe spirals 2 and 5 there is twice the installation distance at the connection point, while the pipe spirals 2 and 5 are only a simple distance apart vertically.
- the pipe spiral 4 is the incorporation of the pipe spirals into several distributor and collecting pipes 3 and 4 shown.
- the upper tube spiral 2 begins in the first distributor tube 3 and ends in the same Level in the first collecting tube 4.
- the tube spiral 5 underneath begins in the second distributor pipe 3 and ends in the second header pipe 4. Also at this embodiment is sufficient with minimal vertical expansion of the tube bundle Space for the installation of the individual spirals gained.
- the individual manifolds and manifolds 3 and 4 are each connected and have a common inflow and outflow.
