Abstract
Abstract High-temperature storage battery with a double-walled housing and insulating material between the housing walls. At least one storage cell as well as a heat sink is arranged in the interior of the housing. The cooling device for the storage cell is designed as a heat exchanger and at least one and preferably several storage cells are associated with each exchanger.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
231 words
A high-temperature storage battery comprising a double-walled housing with insulating material between the two walls of the housing, a plurality of storage cells in the interior of the housing associated with one or more heat exchangers in the form of a slab-shaped heat sink which have at least two large cooling surfaces and in their interior several cooling loops, each cooling loop formed by at least two canals arranged vertically one below the other and connected to each other at a first end of the heat sink via a deflection opening, each cooling loop having only one entrance opening and only one exit opening for introduction and discharge of a cooling medium, the entrance opening is in communication with a common feed canal and the exit opening is likewise in communication with a common discharge canal for the coolant, the entrance opening of the cooling loop is arranged at a second end of the heat sink in the vicinity of a first cooling surface of said two large cooling surfaces and the exit opening of the cooling loop is installed at the second end in the vicinity of the second cooling surface of said two large cooling surfaces, the storage cells having their longitudinal axes perpendicular to the canals of the cooling loops, and the storage cells arranged in a row and installed in a heat-conducting connection along the cooling surfaces.
