Hochtemperaturbatterie

摘要

In high-temperature battery for-the power supply of electrically powered vehicles, having a thermally insulating housing 2 and a cooling system with a cooling body 6 which is arranged inside the thermally insulating housing for cooling cells 5, through which body air flows and which penetrates the thermally insulating wall of the housing 2 solely by means of air inlet 3 and air outlet (4 Fig. 2b) connecting elements arranged on it, to achieve better cooling action, the cooling body 6 is formed by a parallel arrangement of plate-shaped cooling-body elements 7 through which air flows and which are designed as hollow bodies, the bar-shaped battery cells 5 being arranged in the space between the cooling-body elements, and an inlet funnel 8 which widens downstream in breadth distributes coolant over the inlet openings of all the cooling body elements 7 and an outlet funnel (14 Fig. 2b) which narrows downstream in breadth collects coolant flowing out of the outlet openings of all the cooling body elements. Baffle plates may be arranged inside each cooling body element.
