    [0001] The present disclosure relates to a battery cooling system and a battery shelf applied to it, and more specifically, to a battery cooling system having a Z-type cooling channel and a battery shelf applied to it.
    [0002] The present disclosure claims priority for Korean Patent Application No. 10-2011-0052262 filed in the Republic of Korea on May 31, 2011 and the disclosures are incorporated herein by reference.
    [0003] In addition, the present disclosure claims priority for Korean Patent Application No. 10-2012- 0051678, filed in the Republic of Korea on May 15, 2012, and the disclosures are incorporated herein by reference. TECHNICAL FUNDAMENTALS
    [0004] A battery shelf having a plurality of battery modules loaded in it includes a frame manufactured to have an appropriate hexahedral shape, a plurality of horizontal strips dividing the frame into a plurality of levels and installing and securing the battery modules in that place, panels side, top, bottom and rear respectively fixed to the sides, top, bottom and back of the frame, and a door or front panel coupled to the front portion of the frame.
    [0005] The battery rack is coupled with a predetermined cooling device to properly maintain the temperature of the battery modules installed inside the rack. To couple the cooling device, slits are formed in the upper and lower panels of the battery rack to allow a coolant such as air to pass through. The upper and lower panels are connected respectively to a refrigerant introduction duct and a refrigerant release duct. In this configuration, if a refrigerant forcibly blows into the refrigerant delivery duct or discharges forcefully from the refrigerant release duct, a refrigerant flows from top to bottom on the battery shelf, and the refrigerant flows. from the top to the bottom it passes through channels (cracks) formed in the battery modules attached to the slats. In this process, the heat generated from the battery modules is absorbed by the refrigerant and discharged to the outside.
    [0006] Figure 1 is a schematic view showing a conventional battery cooling system to which the refrigerant flow as described above is applied.
    [0007] With reference to Figure 1, the conventional battery cooling system has a structure in which a cooling channel is formed on a shelf for battery 1, where the battery modules 2 stacked in the vertical direction are loaded, to pass through the modules battery 2 in the direction from the top to the bottom (see the arrow in Figure 1).
    [0008] In this case, a temperature variation occurs between the battery modules 2 charged at different levels and the cooling channel is stretched to cause a relatively large differential pressure between them. The relatively large differential pressure acts as a factor by increasing the temperature variation of battery modules 2 charged at different levels.
    [0009] Generally, a battery's durability deteriorates significantly if the battery's internal temperature exceeds a specific temperature. Therefore, the temperature variation between battery modules 2 loaded at different levels from the shelf to battery 1 negatively affects the operating performance and durability of the battery modules 2.
    [0010] Consequently, a battery cooling system to minimize a temperature variation between the battery modules loaded on the shelf for the battery is in great demand.
    [0011] However, as a shelf for the conventional battery is commonly placed inside an automobile or in power transmission installations, people or users are likely to see it. However, as facilities such as an energy storage system, an electric vehicle charging device or the like, are more likely to be placed in a residence or a location having a large floating population, a battery cooling system having an appearance nice, despite a cooling device loaded in it, is also in demand.

BEST MODE
    [0040] In the following, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Prior to the description, it should be understood that the terms used in the specification and the appended claims should not be considered as limited to common and dictionary meanings, but interpreted based on the meanings and concepts in accordance with the technical aspects of the present disclosure based on on the principle that the inventor is allowed to define terms appropriately for better explanation. Therefore, the description proposed here is only a preferable example for the purpose of the illustrations only, not intended to limit the scope of the disclosure, so it should be understood that other equivalents and modifications could be made to it without departing from the essence and scope of revelation.
    [0041] Next, the configuration of a battery cooling system 10 according to an embodiment of the present disclosure will be described in detail with reference to Figure 2.
    [0042] Figure 2 is an exploded perspective view showing a battery cooling system according to an embodiment of the present disclosure.
    [0043] Referring to Figure 2, the battery cooling system 10 according to an embodiment of the present disclosure includes a shelf for battery R and a battery module M.
    [0044] The battery shelf R is a frame on which the battery modules M are loaded, and includes a main frame 11, a space-dividing frame 12, a coolant guide plate G, side panels 15, a top panel 16 , a front panel 17 and a back panel 18. The M battery modules include a first M1 battery module loaded on a first shelf level for battery R and a second M2 battery module loaded on a second level adjacent to the first level and located under it, and each M1, M2 battery module has heat release slits C formed at least on its upper and lower sides.
    [0045] The main frame 11 defines a shelf structure for the battery R and provides an internal space in which the battery modules M are accommodated.
    [0046] The space-dividing frame 12 divides the internal space provided by the main frame 11 into a plurality of levels and supports the bottom edge of the battery modules M, so that the battery modules M can be loaded into the main frame 11 Although it is illustrated in the drawings that only two space-dividing frames are provided and thus the M battery modules are loaded on both levels, the present disclosure is not limited to this. That is, it is also possible that three or more space-dividing frames 12 are provided, and thus the M battery modules are loaded on three or more levels, as is obvious in the art.
    [0047] The refrigerant guide plates G are installed respectively on the upper and lower ends of the battery modules M and installed so that they are inclined in the same direction at predetermined angles with respect to their surfaces, top and bottom. A pair of refrigerant guide plates G is installed respectively in the upper and lower portions of the battery modules M loaded at the same level as the shelf for battery R. That is, the refrigerant guide plates G include the first and the second refrigerant guide plate 13a, 13b provided respectively in the upper and lower portions of the first battery module M1, and third and fourth refrigerant guide plates 14a, 14b provided respectively in the upper and lower portions of the second battery module M2.
    [0048] Refrigerant guide plates G provided respectively in the upper and lower portions of the same battery module M can be installed in parallel with each other. That is, the first and second refrigerant guide plate 13a, 13b can be installed in parallel with each other, and the third and fourth refrigerant guide plate 14a, 14b can also be installed in parallel with each other.
    [0049] However, the second refrigerant guide plate 13b and the third refrigerant guide plate 14a, facing each other, are installed so as to be inclined in different directions. More particularly, the second refrigerant guide plate 13b and the third refrigerant guide plate 14a can be in a flat symmetrical relationship. In that case, one end of the second refrigerant guide plate 13b may contact one end of the third refrigerant guide plate 14a in a space formed between the battery modules M1, M2 charged at adjacent levels in the vertical direction.
    [0050] The side panels 15 are coupled to both sides of the main frame 11 and have channel slits 15a formed respectively on one side adjacent to the front surface (direction F) of the shelf for battery R and the other side adjacent to the rear surface (direction B ) from the shelf to battery R. Channel slots 15a are used as a passageway to connect the flow of a refrigerant such as air between the internal space where the battery module M is charged and the external space.
    [0051] The upper panel 16, the front panel 17 and the rear panel 18 are coupled to the upper, front and rear portions of the main frame 11, respectively. The main frame 11 can be coupled to panels 16, 17 and 18 using various known methods including bolting, welding or the like, without being limited to this. However, the front panel 17 can be a hinged door on the main frame 11.
    [0052] In the following, the principle of the battery cooling system 10 for cooling the battery modules M loaded therein according to an embodiment of the present invention will be described in detail with reference to Figures 3 to 5.
    [0053] Figure 3 is a side view showing the battery cooling system in Figure 2, where the refrigerant flow (inflow and outflow) is illustrated, Figure 4 is a schematic front view showing the battery cooling system in Figure 2, where the refrigerant flow (inflow) is illustrated, and Figure 5 is a schematic rear view showing the battery cooling system of Figure 2, where the refrigerant flow (flow) is illustrated.
    [0054] Referring to Figures 3 to 5, the channel slots 15a include a first channel slot S1, a second channel slot S2, a third channel slot S3 and a fourth channel slot S4, which are formed in different positions.
    [0055] The first channel slot S1 is formed in an area D1 of the side panel 15, which corresponds to a space between the first refrigerant guide plate 13a and the first battery module M1, and the second channel slot S2 is formed in a area D2 of side panel 15, which corresponds to a space between the second refrigerant guide plate 13b and the first battery module M1. In addition, the third channel slot S3 is formed in an area D3 of the side panel 15, which corresponds to a space between the third refrigerant guide plate 14a and the second battery module M2, and the fourth channel slot S4 is formed in an area D4 of the side panel 15, which corresponds to a space between the fourth refrigerant guide plate 14b and the second battery module M2.
    [0056] The first slit of channel S1 acts as an air passage serving as a refrigerant that flows from the outside of the shelf to the battery R to its inside. The refrigerant flowing into the battery shelf is guided by the first refrigerant guide plate 13a and passes around the heat release slits C (see Figure 1) formed in the first battery module M1 to absorb the heat emitted from of the heat release slits C, which increases the temperature of the refrigerant. The increased temperature refrigerant is guided by the second refrigerant guide plate 13b and completely discharges off the shelf into battery R, thereby cooling the first battery module M1.
    [0057] However, if the first M1 battery module has the heat release slits C at least on its upper and lower sides, the refrigerant passes not only around the heat release slits C, but also through the first battery module M1, which can improve cooling efficiency. That is, the refrigerant flows into the first battery module Ml through the heat release slot C formed on the top surface of the first battery module Ml, absorbs the heat generated from a battery cell (not shown) and then discharges through of the heat release slot C formed on the bottom surface of the first M1 battery module. The refrigerant discharging out of the first battery module M1 is guided by the second refrigerant guide plate 13b and completely discharges out of the shelf into the battery R through the second channel slot S2, thereby cooling the first battery module M1.
    [0058] Similarly, the fourth channel slot S4 functions as a passage of a refrigerant that flows from the outside of the shelf to the battery R into it. The refrigerant flowing to the battery shelf R is guided by the fourth refrigerant guide plate 14b to pass around the heat release slits C (see Figure 1) formed in the second battery module M2 and then guided by the third guide plate of refrigerant 14a to discharge off the shelf into battery R through the third channel slot S3.
    [0059] In addition, if the second M2 battery module has the heat release slots C at least on its upper and lower sides, the cooling efficiency can be improved by allowing a refrigerant to pass through the second M2 battery module, similar to the case of the first M1 battery module.
    [0060] However, a cooling fan (not shown) can be provided for at least one of the areas D1 and D2 and at least one of the areas D3 and D4 in order to make the inflow or forcible flow of a refrigerant. When the cooling fan operates, the refrigerant moves by force in a Z-shaped pattern approximately along the direction of the arrow, so that the M battery modules can be cooled efficiently. The cooling fan is preferably installed on the inner side of the side panel 15 in consideration of the appearance of the battery cooling system 10.
    [0061] In the following, the battery cooling system 20 according to another embodiment of the present invention will be described in detail with reference to Figures 6 to 8.
    [0062] Figure 6 is a side view showing the battery cooling system according to another embodiment of the present disclosure, where the refrigerant flow (inflow and outflow) is illustrated, Figure 7 is a schematic front view showing the battery cooling system. battery according to another embodiment of the present disclosure, where the refrigerant flow (inflow) is illustrated, and Figure 8 is a schematic rear view showing the battery cooling system according to another embodiment of the present disclosure, where a flow of refrigerant (flow) is illustrated.
    [0063] Most components of the battery cooling system 20 of this modality are identical to that of the battery cooling system 10 according to the previous modality of the present disclosure, except for the installation direction of the refrigerant guide plates G and the slots positions channel 15a through which a refrigerant flows in or out. When describing the battery cooling system 20 of this modality, repetitive description will be omitted, and the battery cooling system 20 of this modality will be described based on the installation direction of the refrigerant guide plates G and the positions of the channel slots 15a through which a coolant flows in and out.
    [0064] With reference to Figures 6 to 8, the refrigerant guide plates G are installed respectively on the upper and lower ends of the battery modules M so that they are inclined in the same direction at predetermined angles with respect to their surfaces, top and bottom . The refrigerant guide plates G are installed in the upper and lower portions of the battery modules M loaded on the same level as the battery shelf R. That is, the refrigerant guide plates G include the first and second refrigerant guide plate. 13a, 13b respectively provided in the upper and lower portions of the first battery module M1 and third and fourth refrigerant guide plate 14a, 14b provided respectively in the upper and lower portions of the second battery module M2. The refrigerant guide plates 13a, 13b, 14a, 14b are installed so as to be inclined in the same direction and the plates can also be installed entirely or partially so that they are parallel to each other.
    [0065] As the installation directions for the refrigerant guide plates G are varied, the refrigerant to cool the second battery module M2 flows on the shelf to battery R through the third channel slot S3 formed in area D3 and discharges out through the fourth slot channel S4 formed in area D4, opposite to the previous modality.
    [0066] As described above, as the battery cooling system 10, 20 according to the present embodiment has channel slits 15a between the shelf levels for battery R for inflowing or draining a refrigerant to diverge the air flow, excellent cooling effects are presented. That is, as the battery cooling system 10, 20 in accordance with the present disclosure decreases the length of the channel slots, it is possible to decrease a temperature variation between the M1, M2 battery modules loaded at different levels and smooth the increase differential pressure.
    [0067] The previous exemplary modalities and advantages are only explanatory and should not be considered as limiting the present inventive concept. In addition, the description of the modalities of the present disclosure is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be evident to those skilled in the art.
