Heat-exchanger esp for vehicle cooling system - has hollow chamber arrangement with network of recesses woven or arranged in all spatial directions in grid structure

摘要

The heat-exchanger (10) has a head conductive body (11,12) and a hollow chamber arrangement associated with the heat conductive body (11,12). A gaseous of fluid heat conductive medium flows through the hollow chamber arrangement. The heat conductive body has a three dimensional grid structure. The hollow chamber arrangement is passed through by a network of recesses. The network is entwined or woven into the grid structure in all spatial directions. The heat conductive body preferably has a uniform structure. The network preferably also has a uniform construction. The heat conductive body may be formed of several three dimensional grid elements with pairs of V-shaped element parts running in two perpendicular planes.
