Abstract

The invention relates to a solid oxide battery module temperature control assembly, which comprises a heat preservation cover, a temperature control plate and insulating plates, an inlet and an outlet are respectively arranged at two transverse sides of the heat preservation cover, the insulating plates are symmetrically arranged at the top and the bottom in the heat preservation cover, and the temperature control plate is arranged between the insulating plates and the inlet. The side, facing the inlet, of the temperature control plate is a plurality of slopes, the side, facing the outlet, of the temperature control plate is a plane, and a plurality of gas channels penetrating to the slopes are formed in the plane. According to the invention, the temperature control plate and the flow guide plate of the gas are additionally arranged in the galvanic pile module, so that the problems of poor heat dissipation at the middle position and good heat dissipation at the peripheral position in the running process of the galvanic pile are solved, the influence on the performance of the galvanic pile and the system due to temperature difference expansion between the galvanic piles is avoided, and the control on the temperature distribution in the galvanic pile module is passively realized; the stack module with uniform temperature distribution greatly reduces the damage risk of the stack, reduces the control difficulty of a power generation system, improves the power generation efficiency and shortens the loading time.
