The utility model relates to a temperature conditioning and air guiding device. The temperature conditioning and air guiding device comprises an air guide plate, a fan and a mounting seat which is used for mounting the air guide plate; the air guide plate consists of a heat conducting ceramic substrate and an electric heating device, wherein the heat conducting ceramic substrate is provided with air guide holes, and the electric heating device is integrally arranged inside or on the external surface of the heat conducting ceramic substrate; and the mounting seat comprises a plate-shaped base body and a columnar fan fixing seat, wherein the fan fixing seat is provided with a fan mounting hole, two fixing plates which are used for fixing the air guide plate are arranged at the end parts of the two ends of the plate-shaped base body, and clamping structures which are used for clamping the air guide plate are arranged at corresponding positions on the opposite faces of the two fixing plates. According to the temperature conditioning and air guiding device, the air guide plate is placed in a battery box when the air guide plate is used, does not generate heat and only play an air guiding role when cooling is needed, and can guide air as well as electrically heat in cold environments, so that an air heater and a structure for fixing the air heater can be omitted; and the air guide plate and the fan are arranged on the same fixing seat, so that the valuable space inside the battery box is greatly saved, and the manufacturing cost is reduced.
