Embodiment Construction

[0019] exist figure 1 In the plant leaf 1 shown, the problem of distributing the water supplied via the petiole to all the cells of the leaf through the network of veins 2 with minimal energy utilization has been solved over millions of years of evolution. The system of veins 2 comprises a main shaft 3 , which continues in a straight line from the petiole, from which cotyledonary veins 4 distributed over the length of the main shaft or at the root of the main shaft form.

[0020] As the distance from the main axis 3 increases, the cotyledon veins 4 branch off one or more times.

[0021] figure 1 The heat exchanger 11 schematically shown in the figure adopts the bifurcated tube structure of the plant leaf 1, but the fundamental difference from the plant leaf 1 is that the heat transfer fluid supplied at the input connection 12 cannot be like the water supplied to the leaf 1 That evaporates and has to be sent away again via the output connection 13 . However, the flow-promoti...

Abstract

Disclosed is a heat exchanger (11) comprising a two-dimensional branched pipe structure for a heat transfer fluid. The branched pipe structure has a plurality of branching points and junction points (15, 17, 19) between an inlet connection (12) and an outlet connection (13). The junction points (19) are all arranged in an external edge region (27) of the pipe structure and are connected via a collecting pipe (14) that extends within the edge region (27).

Description

technical field [0001] The invention relates to a heat exchanger, especially a heat exchanger suitable for use as an evaporator in a refrigeration appliance. Existing heat exchangers with unbranched tube structures generally comprise a base plate on which a continuous tube extends serpentinely from an input connection to an output connection. By means of the meandering delicate extension, the temperature change associated with the supply of the heat transfer fluid can be spread over the entire surface of the substrate in a short time. However, it has the disadvantage that the large length of the individual tubes causes a sudden drop in the pressure of the heat transfer fluid in the heat exchanger, thus requiring a high driving power to circulate the heat transfer fluid. The serpentine route enables heat exchange between adjacently extended upstream and downstream sections of the tube, which reduces the efficiency of the heat exchanger. Background technique [0002] A heat ...
