[0032] Figure 1 It is a bottom perspective view of the temperature control device of the energy storage system of the present invention; Figure 2 This is an exploded perspective view of the lower side of the temperature control device for the energy storage system of the present invention; Figure 3 is Figure 2 An exploded perspective view of the lower side of the energy storage system temperature control device with the cover removed; Figure 4 is Figure 3 An exploded perspective view of the lower side of the energy storage system temperature control device with the cooling fan portion removed; Figure 5 is Figure 4 An exploded perspective view of the lower side of the energy storage system temperature control device with the transfer fins removed.

[0033] The embodiments of the present invention are described with reference to the accompanying drawings. The temperature control device for an energy storage system of the present invention may be composed of a housing 100 , a temperature control element 200 , and a heat dissipation unit 300 .

[0034] The housing 100 is formed in a right hexahedron shape, and a space for accommodating the energy storage system is formed inside the housing 100. The housing 100 may be composed of a side wall 120, a lower side 130, and an upper side 110.

[0035] To replace the energy storage system, the housing 100 can be formed so that the upper side 110 can be detachably formed. Therefore, by removing the upper side 110 of the housing 100, the user can expose the interior space of the housing 100 to the outside. Therefore, the energy storage system stored inside the housing 100 can be replaced. On the other hand, the housing 100 does not necessarily have to have a structure in which only the upper side 110 can be detached. Depending on the use, the housing 100 can also be formed so that a portion of the side wall or the lower side 130 can be detached. In other words, as long as the interior of the housing 100 can be exposed to the outside, there is no problem.

[0036] On the other hand, the housing 100 is different from the above-mentioned one, and the housing 100 itself can be sealed. Therefore, there is a way to replace the entire housing 100 in the event of a problem with the energy storage system.

[0037] A temperature control element 200 may be configured on one side of the housing 100. More preferably, Figure 1 Confirmed in, but from Figure 5 It can be confirmed that it can be arranged on the lower side 130 of the housing 100. The temperature control element 200 can cool or heat the control surface as the power is supplied. Here, the control surface of the temperature control element 200 can be the surface that is in contact with the housing 100. Figure 5 The upper side surface may be the control surface.

[0038] Temperature control element 200 cools the control surface when supplied with a first power source and heats the control surface when supplied with a second power source. Temperature control element 200 can vary its cooling and heating temperatures based on the polarity and intensity of the first and second power sources. The opposite side of the control surface of temperature control element 200 can be a corresponding surface. The corresponding surface and the control surface can experience opposite temperature changes. That is, if the control surface of temperature control element 200 is cooled, the corresponding surface can be heated.

[0039] In the opposite case, if the control surface of the temperature control element 200 is heated, the corresponding surface can be cooled. Figure 5 It can be confirmed that a plurality of temperature control elements 200 can be configured.

[0040] The heat dissipation unit 300 can be connected to the temperature control element 200. The heat dissipation unit 300 is connected to the corresponding surface of the temperature control element 200, and can release the temperature of the corresponding surface to the outside.

[0041] As described above, the present invention houses the energy storage system in a housing 100, controls the temperature of the housing 100 through the temperature control element 200, and releases heat to the outside when necessary by operating the heat dissipation unit 300. Therefore, the present invention can easily control the temperature of the batteries in the energy storage system and can be miniaturized. As can be seen from these descriptions, the temperature control element 200 and the heat dissipation unit 300 of the present invention are the characteristics of the invention. Figures 2 to 5 The heat dissipation unit 300 and the temperature control element 200 are described in detail.

[0042] from Figure 1 As can be seen in the figure, when observing the heat dissipation unit 300 from the outside, only the cover 310 is visible. The cross-section of the cover 310 is a rectangular hexahedron similar to that of the housing 100. However, unlike the housing 100, omitting the upper side of the cover 310 is not a problem. This is because the lower side 130 of the housing 100 closes the upper side of the cover 310. The cover 310 may be formed with multiple heat dissipation holes. Therefore, the air inside the cover 310 can communicate with the external air. Therefore, the cover 310 can release heat generated when the corresponding surface is heated to the outside.

[0043] On the other hand, to avoid blocking the heat dissipation holes of the cover 310, the housing 100 may be formed with legs 150. Legs 150 serve to separate the cover 310 from the ground. Therefore, the heat dissipation holes of the cover 310 do not need to be blocked. The shape of the legs 150 is not a problem as long as they separate the cover 310 from the ground without blocking the heat dissipation holes.

[0044] For example, the leg 150 may be formed on the side of the housing 100 to be longer than the longitudinal length from the position where the leg 150 is formed to the cover 310. That is, the lower end of the leg 150 contacts the ground to physically raise the shape of the cover 310. Figure 2 As shown, the leg 150 is formed into a U-shape, and the area in contact with the ground is large, so it can be stably supported by the ground. On the other hand, although not shown, the heat dissipation hole can also be configured with a filter to prevent external foreign matter from passing through while allowing air to pass through.

[0045] In order to release heat through the heat dissipation holes of the cover 310, a structure that can forcibly move heat is required. Figure 3 、 4 This can be achieved through the cooling fan unit 320 and the transfer fin unit 330. The cooling fan unit 320 generates wind in one direction when powered. For example, the cooling fan unit 320 may consist of a fin unit and a motor, with the motor rotating the fin unit about an axis. Therefore, when powered, the cooling fan unit 320 can forcibly move air. Consequently, heat generated on the corresponding surface can be dissipated to the exterior of the cover 310 through the heat dissipation holes in the cover 310.

[0046] The transfer fins 330 physically transfer heat. A transfer surface 331 is formed on the upper side of the transfer fins 330, and multiple ridges 332 may be formed extending from the control surface. Thus, the transfer fins 330 transfer heat from the control surface through the ridges 332. Furthermore, the multiple ridges 332 enhance thermal conductivity. The aforementioned cooling fan unit 320 is positioned on the ridges 332, allowing heat from the corresponding surface to be transferred through the transfer fins 330 and released to the exterior of the cover 310.

[0047] Finally, the temperature control element 200, a characteristic feature of the present invention, can be disposed on one side (the lower side) of the housing 100. As described above, the temperature control element 200 can be composed of a control surface and a corresponding surface. The control surface can be heated or cooled, and the corresponding surface can operate in the opposite direction according to the operation of the control surface.

[0048] On the other hand, a plurality of temperature control elements 200 may be provided; although not shown, a pattern may be formed on the lower side of the housing 100 in order to facilitate temperature control by the temperature control element 200 .

[0049] In addition, a setting groove 131 may be formed on the lower side of the housing 100. The setting groove 131 can accommodate a portion of the temperature control element 200. Therefore, the temperature (heating, cooling) controlled by the temperature control element 200 can be more easily transmitted to the energy storage system.

[0050] As described above, in the present invention, the temperature control element 200 can easily control the temperature and release heat to the outside as needed, so the temperature of the energy storage system can be controlled even in a small size.

[0051] The present invention has been illustrated and described above in relation to specific embodiments, and various modifications and changes can be made without departing from the scope of the invention and the scope of the invention as expressed in the claims, and can be easily understood by anyone with general knowledge in the relevant field.
