Abstract

The invention relates to a casing for receiving at least one energy storage device, whereof the temperature in the casing interior can be regulated to a predetermined temperature level. For this purpose the casing interior is thermally insulated and is in direct heat conducting connection with a heat transfer device, substantially the entire heat flow into and out of the casing interior taking place through the heat transfer device when the casing interior is closed.

Claims

1. A cabinet for receiving energy storage devices (12), comprising:

a casing (10) having side walls (14), a rear wall (18), a door (16), a top (42), and a bottom (43), all of the side walls (14), rear wall (18), door (16), top (42), and bottom (43) having an inside,

a thermally insulated casing interior (22), the casing interior (22) including insulating inserts (24) on the inside of the side walls (14), rear wall (18), door (16), top (42), and bottom (43), and having a closed condition,

a plurality of heat transfer means (30) for regulating the temperature of the casing interior (22) to a predetermined temperature level, the heat transfer means (30) being in direct heat conducting connection with the casing interior (22), the entire heat flow into and out of the casing interior (22) taking place through the heat transfer means when the casing interior (22) is in the closed condition,

a heat exchanger (20) in the area of the rear wall (18), the heat exchanger (20) having a flow channel (40) and at least one delivery means (44) for delivery of a cooling medium through the flow channel (40),

the heat transfer means (30) being connected in conducting manner to the heat exchanger (20),

wherein;

the heat exchanger (20) has a spine fin recuperator (38) having a spine fin structure, the spine fin structure being integrated into the rear wall (18) of the casing (10);

the casing interior (22) is provided with a frame (26) having superimposed shelves (28) for receiving the energy storage devices (12), each shelf (28) being connected in heat conducting manner with one of the heat transfer means (30), and

the insulating insert (24) on the inside of the rear wall (18) is provided with reception openings (32) for receiving a heat transfer means (30), whereby each reception opening (32) is oriented both vertically and horizontally centrally with respect to one of the shelves (28) of the frame (26).

2. The cabinet according to claim 1, wherein the heat transfer means are constructed as Peltier elements (30).

3. The cabinet according to claim 1, wherein the at least one delivery means is an axial flow fan (44).

4. The cabinet according to claim 1, wherein the delivery means (44) is switched off if the heat transfer means (30) heats the casing interior (22).

5. The cabinet according to claim 1, wherein each heat transfer means (30) is connected in heat conducting manner to the corresponding shelf (28) of the frame (26) in the casing interior (22) with the aid of a heat transmitting element (34).

6. The cabinet according to claim 5, wherein each transmitting element (34) is arranged in the reception opening (38) of the insulating insert (24) and is positioned between the corresponding shelf (28) and the heat transfer means (30).

7. The cabinet according to claim 5, wherein the heat transmitting element (34) is made from a material having a high thermal conductivity A.

8. The cabinet according to claim 1, wherein the heat transfer means (30) is connected in heat conducting manner to the heat exchanger (20) by a further heat transmitting element (36).

9. The cabinet according to claim 8, wherein each further transmitting element (36) is arranged in the reception opening (38) of the insulating insert (24) and is positioned between the heat exchanger (20) and the corresponding heat transfer means (30).

10. The cabinet according to claim 8, wherein the further heat transmitting element (36) is made from a material having a high thermal conductivity.

11. The cabinet according to claim 1, wherein at least two of the shelves (28) are connected in heat conducting manner by at least one heat transmitting element (34) and the heat transmitting element (34) is thermally coupled to one of the heat transfer means (30).

12. The cabinet according to claim 1, wherein the energy storage device (12) has at least one accumulator and at least one battery.

13. The cabinet according to claim 1, wherein the energy storage device (12) has at least one accumulator.

14. The cabinet according to claim 1, wherein the energy storage device (12) has at least one battery.
