Embodiment Construction
[0037] Figure 1A to Figure 1D Four different embodiments of heat transfer modules 10, 20, 30, 40 are shown, each of which can be formed such as Figure 2 to Figure 5 One of the layers of the multilayer body 102, 202, 302 of the heat exchanger 100, 200, 300 is shown. Each heat exchanger multilayer body 102, 202, 302 includes such as Figure 1A to Figure 1D A plurality of heat transfer modules 10, 20, 30, 40 are shown in . If desired, only one type of heat transfer module 10 , 20 , 30 , 40 may be employed in the heat exchanger multilayer body 102 , 202 , 302 . Alternatively, however, it is also conceivable to equip the heat exchanger multilayer body 102, 202, 302 with e.g. Figure 1A , Figure 1B , Figure 1C or Figure 1D At least two different types of heat transfer modules 10, 20, 30, 40 are shown in .
[0038] Figure 1A The heat transfer module 10 shown in includes a heat transfer module body 10a and ribs or fins 12 integrally formed with the heat transfer module bod...

Abstract
A Heat exchanger (100, 200, 300) comprises a plurality of heat transfer modules (10, 20, 30, 40) which are disposed side by side so as to define a multilayer body (102, 202, 302) of the heat exchanger (100, 200, 300), wherein each heat transfer module (10, 20, 30, 40) is provided with at least one heat transfer medium channel (14, 24, 34, 44) designed to allow a flow of a heat-carrying medium therethrough, wherein at least one portion of the multilayer body (102, 202, 302) of the heat exchanger (100, 200, 300) is provided with a curvature which is designed so as to allow the heat exchanger (100, 200, 300) to be used as a curved outer skin section of a craft, and wherein adjacent heat transfer modules (10, 20, 30) of said at least one portion of the multilayer body (102, 202, 302) are arranged with a tilt angle of their central axes (A); towards each other such that each heat transfer module (10, 20, 30, 40) is aligned towards the center of a local osculating circle defined by an outer surface (106, 206, 306) of the heat exchanger (100, 200, 300).
Description
technical field [0001] The invention relates to an aircraft outer skin heat exchanger, to the use of such an outer skin heat exchanger in an aircraft and to a method for producing such an aircraft outer skin heat exchanger. Background technique [0002] Fuel cell systems are capable of generating electricity with low emissions and high efficiency. To this end, efforts are currently being made to use fuel cell systems to generate electrical energy in various mobile applications such as, for example, in automotive engineering or aeronautics. For example, it is conceivable to use fuel cell systems in aircraft to replace generators, which are currently used to provide electrical power on board and which are driven by the main engines or auxiliary power units (APUs). In addition, fuel cell systems can also be used to provide emergency power to aircraft and replace ram air turbines (RATs) that have been used as emergency power systems until now. [0003] In addition to electrica...
