Latent cold storage device

摘要

The invention relates to a latent cold storage device with an improved structure and an improved mode of operation by means of a sandwich-type arrangement of the heat conducting elements and cold storage elements, whereby the cold storage elements made in the form of pockets containing a cold storage medium, are deformable.

主权项

1. A latent cold storage device (100), in particular for a vertical air conditioning system of a vehicle with a cold storage medium (3), wherein the latent cold storage device (100) comprises a plurality of heat conducting elements (1) having at least one plate-shaped section (1a) and a plurality of cold storage elements (2) wherein the heat conducting elements (1) and the cold storage elements (2) are connected in an alternating sandwich fashion such that at least some cold storage elements (2) abuts two plate-shaped sections (1a), wherein heat is exchanged directly through the abutment between the heat conducting elements (1) and the cold storage elements (2), wherein the cold storage elements (2) are deformable pockets, and wherein at least one tube (10) conveying circuit medium for charging (10a) and/or discharging (10b) the cold storage elements (2) is at least partially connected with the heat conducting elements (1) such that there is a positive interlocking and/or frictional engagement between the tube (10) and the heat conducting element (1), and wherein heat is exchanged directly between the at least one tube (10) and the cold storage elements (2), and directly between the at least one tube (10) and the plate-shaped sections (1a) of the heat conducting elements (1) for further transfer into the cold storage elements (2);
at least one pair of adjacent cold storage elements (2) having opposed ends forming an expansion area; and wherein the at least one tube (10) has a portion that extends adjacent both the at least one expansion area and adjacent at least one of the opposed ends forming the expansion area.
