Japanese Patent No. 4845984

By the way, in the conventional tank floor member 103 of the culture medium cultivation tank Sa, since there is one storage groove 105 in which the heat exchanger H is put, a plurality of heat exchangers H are provided to perform heating or cooling. There has been a problem that it is not possible to cope with the case where it is desired to increase the heat exchange capacity. In order to cope with the problem, a tank floor member having a plurality of storage grooves 105 may be separately prepared and used. However, in this case, the type of the tank floor member increases, and the manufacturing is complicated. And the storage and management become complicated.
The present invention has been made in view of such a problem, and it is possible to provide heat exchange bodies of different numbers even by one kind, and to widen a setting range of a heat exchange ability to improve versatility. In addition, an object of the present invention is to provide a tank floor member and a tank that are easy to manufacture, store, and manage.

The tank floor member of the present invention for achieving such an object is a floor portion of a tank in which a liquid and / or solid medium is placed, and performs heat exchange with the medium along one direction. A tank floor member that constitutes a whole or a part of a floor portion to which a tubular heat exchanger is attached, and that is formed in a rectangular plate shape and is continuously arranged in a plurality along the one direction to form a row portion,
One surface capable of forming a floor surface of the floor portion, the other surface capable of forming a floor surface of the floor portion, a pair of outer ends along the one direction, and a shape orthogonal to the one direction and joined to each other. The pair of joining side ends is formed, and the floor surface of the row-shaped portion can be formed by one of the one surface and the other surface, and the heat exchanger is disposed on the one surface side along the one direction. Forming one or more storage grooves capable of storing and holding, and forming one or more storage grooves capable of storing and holding the heat exchanger along the one direction on the other surface side; The number of storage grooves on one side is different from the number of storage grooves on the other side.
Here, in the heat exchange between the medium and the heat exchanger, when heat is applied to the medium by heating or cooling the medium by the heat exchanger, the heat is cooled or cooled by the medium to transfer heat from the medium. Including any case of taking out.

  When the floor of the tank is formed using the tank floor member, the storage formed on one side and the other surface of the tank floor member according to the heat exchange capacity of the heat exchanger required by the tank. The number of heat exchangers to be arranged is determined in accordance with the number of grooves, and one of the surfaces of the tank floor member and one of the other surfaces are set to the floor surface in accordance with the number of the heat exchange members, and the tank floor member is sequentially placed at the joining end thereof. Join and assemble a row of required length. Then, a floor portion is formed by arranging one or a plurality of the row portions in another direction orthogonal to one direction. After that, the heat exchanger is housed and held in the housing grooves of the row portion. Further, a side wall is constructed on the floor portion, and a tank is formed by appropriately covering the floor surface and the inner surface of the side wall with a covering member such as a sheet. In the tank constructed in this way, for example, when heating or cooling the medium by a heat exchanger to apply heat to the medium, when the temperature of the medium is low, the medium is heated by the heat exchanger, and the medium is heated. When the temperature is high, the medium is cooled by the heat exchanger so that the temperature of the medium is always kept properly. In this case, even if one kind of tank floor member is used, it is possible to provide a different number of heat exchangers by selecting either one side or the other side. Performance can be improved. In addition, the manufacture, storage, management, and the like of the tank floor member are also facilitated.

In addition, if necessary, a first engagement projection is formed on one of the pair of joining side ends, the first engagement projection being provided on the one surface side and extending between the pair of outside ends. And a first engaging recess formed on the other surface side and between the pair of outer ends and adjacent to the first engaging convex portion,

A second engaging projection is formed, and the first engaging projection is recessed on the one surface side, between the pair of outer ends, and adjacent to the second engaging projection. It is configured to form a second engaging concave portion having a shape that is in a mating relationship. Since the engaging projections and the engaging recesses are formed on the entire joint side end, the continuous connection can be strengthened.

  Further, if necessary, the first engagement protrusion and the first engagement recess are continuously formed between the pair of outer ends, and the second engagement protrusion and the second engagement recess are formed in the pair of outer ends. It is effective that it is formed continuously between the outer ends. Since the first engagement protrusion, the first engagement recess, the second engagement protrusion, and the second engagement recess are formed continuously, the strength can be increased.

  Furthermore, if necessary, the engagement relationship between the first engagement protrusion and the second engagement recess, and the engagement relationship between the first engagement recess and the second engagement protrusion, The first engagement protrusion, the first engagement recess, the second engagement protrusion, and the second engagement so as to restrict movement in the other direction which is orthogonal to the direction and connects the pair of outer ends. A step is formed in the recess to surround the storage groove. Since movement in the other direction is regulated, positioning is facilitated when assembling the tank floor member in a row, so that assembling can be performed easily and reliably.

If a heat transfer plate is provided, the heat transfer plate will be supported by the support, but the surface of the heat transfer plate will be flush with the general surface of one or the other side of the support. Therefore, adverse effects on the medium can be reduced. In this case, the heat exchanger is in contact with the metal heat transfer plate.For example, when heating or cooling the medium by the heat exchanger to apply heat to the medium, the medium is heated via the heat transfer plate. Although it is heated or cooled, since the heat transfer plate is planar and has a large heat dissipation area, heat from the heat exchanger is uniformly transferred to the medium, and the heat transfer efficiency is improved. On the other hand, for example, when heat is taken out of the medium by heating or cooling the heat exchanger with the medium, the heat transfer efficiency is similarly improved.

  A tank according to the present invention for achieving the above object is a tank in which a medium made of liquid and / or solid is put, and is formed using one of the one surface and the other surface using the tank floor member. A row is formed having a floor surface to be formed, and one or more of the row portions are arranged in a row perpendicular to the one direction and in the other direction connecting the pair of outer ends to form a floor. The heat exchanger is housed and held in the housing groove of the row portion. The same operations and effects as described above are achieved.
