- the exchange surface measured in square meters is at least a factor 20 greater than that outer volume of the housing 40 in cubic meters, as shown in Fig. 20.
- the heat exchanger unit 74 can be designed such that it represents a module and thus there is the possibility, for example, of extending the jacket body 46 to form a jacket body 46 'and retaining the upper housing cover 42 and of the lower housing cover 44, two such heat exchanger units 74 designed as modules can be arranged in an inner space 72 'of such a modified housing 40', so that the exchange area can be further increased in square meters per cubic volume, so that the exchange area now more than a factor of 25 is greater.
- This ratio exchange surface to volume can be increased even further, if, as shown in a third embodiment, the housing 40 "by extending the shell body 46" is still increased so that in the interior 72 "of the housing 40" three heat transfer units 74th as individual modules in the stacking direction 76 are arranged one above the other, so that in this case the ratio of
