Definitions

the invention relates to a heat exchanger for direct heating or cooling of a storage medium, preferably in process water or heating buffer stores.
finned tubes are usually used on the outside of the heat exchanger tube, the large outside surface of which compensates at least partially for the low alpha value on the outside.
the increase in performance that can be achieved does not increase linearly with the increase in surface area, because there is only a very small amount of convection, in particular in the case of the desired small temperature differences, and on the other hand a so-called rib efficiency which is dependent on the rib height becomes effective.
the performance can thus be further improved by forcibly flowing around the finned tube via a pump arrangement (see publication 50.040. 977 by Sulo).
a pump arrangement see publication 50.040. 977 by Sulo.
this design requires a comparatively high amount of energy for the circulation pumps used for this.
the invention is therefore based on the object of improving the efficiency of heat exchangers in containers.
This object is achieved in that the natural thermal convection around the heat exchanger is decisively increased by rising or sinking shafts which extend from the upper to the lower container area and have a flow cross-section which is approximately the same as that of the heat exchanger bundle.
the inflow area to the heat exchanger should consist of the largest possible, preferably horizontal, surface.
the convection effect can be further increased by partially or completely filling the passage cross-sectional areas within the sink shaft funnel that cannot be directly influenced by the heat exchanger. It is also advantageous that the heat exchanger bundle is as small as possible, because this reduces both the natural friction of the container medium and disruptive turbulence, which hinder the convection flow.
the advantages of this sinkhole principle are based on the alpha value of the outer surface, which is considerably improved by the higher convection speed. This greatly increases the performance of the heat exchanger without energy expenditure or a larger construction volume, and there is also the possibility of using cheaper, low-finned pipes.
the invention makes it possible therefore, to equip small, light and inexpensive heat exchangers with high performance without energy and high expenditure on equipment.
Fig. 1 The heat exchanger (1) is in the funnel-shaped head part (2) of the sink shaft (3).
the free cross-section of the heat exchanger which is preferably wound in a spiral, is closed by a lock (4), so that all the water circulated by the convection brushes the finned tubes.
the arrangement of the sealing cap on the end of the heat exchanger facing the sink shaft and the somewhat conical design of the side wall of the head part (2) are advantageous here, because this means that a larger part of the heat exchanger can be acted upon by a storage medium which is still thermally uninfluenced, so that in a larger one Area of the heat exchanger the max. possible temperature difference between the heat exchanger and storage medium can be used.
the arrangement shown serves to cool the storage medium, the arrangement is reversed for heating.
