Abstract

PURPOSE:To reduce manufacturing processes as compared with the former high temperature cell device while making it possible to get rid of generation of a short-circuit when connecting by providing the second heat transfer medium on the space of the collected high temperature cells for making it en bloc with the first heat transfer medium on the lower end part. CONSTITUTION:High temperature cells 1 are housed inside the porous electrically insulated bottomed tubular bodies 9 composed of ceramics or glass while being collectively placed on the top of the first heat transfer medium 10 made of a good heat transfer material of aluminum or the like. Further, the second heat transfer medium 8 made of the same material with the first heat transfer medium is arranged while being made en bloc with the first heat transfer medium 10 on the lower end part. On the other part a heating medium 11 such as an electric heater or the like is laid on the inside bottom of an armored can 6 while thereon the first heat transfer medium 10 is provided. Thereby, the connection is simplified as compared with the former device while being able to housed in a limited space thus reducing manufacturing processes.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high-temperature battery device comprising a plurality of batteries that operate at high temperatures, and more specifically to a collective heating structure for a high-temperature battery device. .

Prior art and origin high temperature battery devices, for example sodium-sulfur t! operated at 550°C! A plurality of I batteries are assembled and connected in series and parallel to each other to heat and keep warm, and have a structure as shown in Fig. 3. In other words, the 31st! ! ! In I, 1 is a high temperature battery, and its cathode current collecting terminal 2 and anode current collecting terminal 4 are connected in parallel through a cathode terminal 3 and an anode terminal 5, respectively. The high-temperature batteries assembled in this way are housed in an exterior can 6 having a heating element 7 on the outer surface, and constitute a high-temperature battery device.

When such high-temperature battery devices are further assembled to increase output, this can be achieved by arranging the above-mentioned outer cans 6 side by side and connecting the respective cathode terminals 3 and anode terminals 5 in series and parallel.

However, in a high-temperature battery device configured in this way, the interconnection of the heating elements 7 is complicated, which not only causes a short circuit, but also requires a large amount of man-hours to assemble the high-temperature batteries 1, and also requires a large amount of space. It has disadvantages such as being large and difficult to accommodate in a limited container, and has low practicality.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a highly practical high-temperature battery device that eliminates the above-mentioned drawbacks.

Composition of the Invention The high-temperature battery device of the present invention has a heating medium such as an electric heater placed on the inner bottom of the outer can, and high-temperature batteries are assembled on the top surface of the can via a first heat transfer medium, and providing a second heat transfer medium in the gap between the assembled high-temperature batteries;
The lower end portion is integrated with the first heat transfer medium.

EXAMPLES The present invention will be explained below using examples. FIG. 1 is a top view of the high temperature battery device of the present invention, and FIG. 2 is a partially cutaway front view of the same. In Figures 1 and 2, the same numbers are used for the same parts as in Figure 3. The high-temperature battery 1 is housed in a porous electrically insulating bottomed cylinder 9 made of ceramic, glass, etc., and assembled on the upper surface of a first heat transfer medium 10 made of a good heat transfer material such as aluminum. 1iA11t. Further, a second heat transfer medium 8 made of the same material as the first heat transfer medium is disposed on the display of the assembled and placed high temperature batteries, and is integrated with the first heat transfer medium 10 at the lower end. It becomes. On the other hand, a heating medium 11 such as an electric heater is placed on the inner bottom surface of the outer can 6, and the first heat transfer medium 10 is provided on the top surface thereof.

Now, 24 cells of high temperature batteries 1 are connected 6 in parallel and 4 in series to configure the high temperature battery device of the present invention as described above and the conventional high temperature battery device as shown in Fig. F3. The number of short circuits, occupied floor space, and volumetric efficiency were compared, and the results are shown in Table 1. Note that the volumetric efficiency is shown without including the heat insulating layer.

Table 1 From Table 1, the high temperature battery device of the present invention can reduce the number of manufacturing steps compared to the conventional high temperature battery device.
It can be seen that not only can generation be eliminated, the occupied floor space can also be reduced, and volumetric efficiency can also be increased.

Effects of the Invention As detailed in the Examples, the high-temperature T& pond device of the present invention is easier to connect than conventional devices, requires fewer manufacturing steps, and can be housed in a limited space. It can be used as a power source for load adjustment, etc.
Its uses can be expanded.

In the present invention, the method of laying the heating medium, the shape of each heat transfer medium, and the shape of the electrically insulating bottomed cylinder can be determined arbitrarily.
