Both methods have relatively high noise and consume a large amount of electric energy to achieve the cooling effect, reducing the overall system efficiency. Due to the relatively complex structure, during actual use, components such as compressors and fans need to be maintained regularly, resulting in high maintenance costs and usage costs. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a modular energy storage heat dissipation device, which has a simple structure, low energy consumption, low noise, high working efficiency, and low maintenance and usage costs.
[0004] To achieve this purpose, the utility model adopts the following technical solutions:
[0005] The utility model discloses a modular energy storage heat dissipation device, including: a collector, which has a liquid cavity and is used to collect the heat generated during the operation of the energy storage system; a radiator, which has a heat dissipation cavity and is buried underground; a circulation pump, which is arranged between the radiator and the collector and is used to drive the liquid to circulate between the liquid cavity and the heat dissipation cavity.
[0006] In some embodiments, a heat-conducting adhesive layer is provided on the side wall of the collector, and the collector is bonded to the energy storage system through the heat-conducting adhesive layer.
[0007] In some embodiments, the radiator includes a plurality of heat dissipation units, and the plurality of heat dissipation units are arranged in multiple rows and columns.
[0008] In some specific embodiments, each heat dissipation unit forms a heat dissipation pipeline.
[0009] In some embodiments, the liquid cavity has a liquid outlet and a liquid return port, and the heat dissipation cavity has a heat dissipation inlet and a heat dissipation outlet; the modular energy storage heat dissipation device further includes a first connection pipe and a second connection pipe. The two ends of the first connection pipe are respectively connected to the liquid outlet and the heat dissipation inlet, and the two ends of the second connection pipe are respectively connected to the liquid return port and the heat dissipation outlet; wherein:
[0010] The circulation pump is arranged on the first connection pipe and / or the second connection pipe.
[0011] In some specific embodiments, a control valve is further provided on the first connection pipe and / or the second connection pipe.
[0012] In some specific embodiments, both the first connecting pipe and the second connecting pipe include an above-ground pipeline and a below-ground pipeline. The above-ground pipeline and the below-ground pipeline are arranged at an angle. The above-ground pipeline is connected to the liquid cavity, and the below-ground pipeline is connected to the heat dissipation cavity.
[0013] In some embodiments, there are multiple collectors, and each collector corresponds to one battery of the energy storage system.
[0014] In some embodiments, there are multiple radiators, and the multiple radiators are respectively connected to the collectors.
[0015] In some embodiments, the materials of both the collector and the radiator are metals.
[0016] The beneficial effects of the modular energy storage and heat dissipation device of the present utility model: During the actual working process, the collector is used to collect the heat generated when the energy storage system works.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.
[0028] The present utility model discloses a modular energy storage and heat dissipation device, such as Figure 1As shown in the figure, the modular energy storage cooling device includes a collector 100, a radiator 200, and a circulation pump 300. The collector 100 has a liquid chamber and is used to collect the heat generated during the operation of the energy storage system. The radiator 200 has a cooling chamber and is buried underground. The circulation pump 300 is arranged between the radiator 200 and the collector 100 and is used to drive the liquid to circulate between the liquid chamber and the cooling chamber. It can be understood that during the actual operation process, the collector 100 is used to collect the heat generated during the operation of the energy storage system. The liquid in the liquid chamber absorbs heat and rises in temperature, and is output to the cooling chamber of the radiator 200 under the drive of the circulation pump 300. Since the radiator 200 is buried underground, the heat carried by the liquid in the cooling chamber can be quickly transferred to the ground and become low-temperature liquid and then return to the liquid chamber again. Thus, under the drive of the circulation pump 300, the heat generated during the operation of the energy storage system can be transferred to the ground during the process of the liquid circulating between the liquid chamber and the cooling chamber. Compared with the existing fan cooling and refrigeration system cooling methods, the electrical equipment of the modular energy storage cooling device in this embodiment only includes a circulation pump 300, with low energy consumption, low noise, and high working efficiency. And since the modular energy storage cooling device only includes three parts: the collector 100, the radiator 200, and the circulation pump 300, the structure is very simple, and both the maintenance cost and the usage cost are relatively low.
[0029] In some embodiments, a heat-conducting adhesive layer is provided on the side wall of the collector 100, and the collector 100 is bonded to the energy storage system through the heat-conducting adhesive layer. It can be understood that the collector 100 is bonded to the energy storage system through the heat-conducting adhesive layer. On the one hand, it can improve the installation stability of the collector 100 and ensure the stable installation of the collector 100 and the energy storage system. On the other hand, the heat-conducting adhesive layer can quickly transfer the heat generated during the operation of the energy storage system to the collector 100, which is absorbed by the liquid in the collector 100, thus helping to improve the cooling efficiency of the modular energy storage cooling device for the energy storage system. Of course, in other embodiments of the present invention, the collector 100 can also be fixed by other methods such as welding, connection by connectors, or clamping, and is not limited to bonding with the heat-conducting adhesive layer.
[0030] In some embodiments, as Figure 2 shown, the radiator 200 includes a plurality of heat dissipation units, and the plurality of heat dissipation units are arranged in multiple rows and multiple columns. It can be understood that setting a plurality of heat dissipation units in the radiator 200 can quickly dissipate heat to the ground and improve the heat dissipation efficiency of the radiator 200. The plurality of heat dissipation units are arranged in multiple rows and multiple columns, which can further improve the heat dissipation efficiency. Of course, in other embodiments of the present invention, the plurality of heat dissipation units can also be arranged in a circular array according to actual needs, etc., and are not limited to the above limitations.
[0031] In some specific embodiments, each heat dissipation unit becomes a heat dissipation pipeline. It can be understood that each heat dissipation unit is composed of a heat dissipation pipeline, which simplifies the structure of the heat dissipation unit on the one hand, makes the structure of the entire radiator 200 relatively simple, and is conducive to reducing the manufacturing cost of the radiator 200. On the other hand, it can increase the heat dissipation area of the heat dissipation unit, thereby improving the heat dissipation efficiency of the radiator 200.
[0032] It should be added that in the embodiments of the present invention, the cross-sectional shape, size, and length of the heat dissipation pipeline can all be selected according to actual needs, and the structure of the heat dissipation pipeline is not specifically limited here. Of course, in other embodiments of the present invention, each heat dissipation unit can also be formed into other structures such as heat dissipation coils, and is not limited to the heat dissipation pipeline of this embodiment.
[0033] In some embodiments, the liquid cavity has a liquid outlet and a liquid return port, and the heat dissipation cavity has a heat dissipation inlet and a heat dissipation outlet; refer to Figure 1 As shown, the modular energy storage heat dissipation device further includes a first connecting pipe 400 and a second connecting pipe 500. The two ends of the first connecting pipe 400 are respectively connected to the liquid outlet and the heat dissipation inlet, and the two ends of the second connecting pipe 500 are respectively connected to the liquid return port and the heat dissipation outlet. It can be understood that the connection between the liquid cavity and the heat dissipation cavity is realized through the first connecting pipe 400 and the second connecting pipe 500, which is convenient for assembly and has good connection tightness, and the probability of liquid leakage is relatively low.
[0034] Optionally, the two ends of the first connecting pipe 400 are respectively welded to the collector 100 and the radiator 200. Thus, on the one hand, it can improve the connection stability between the first connecting pipe 400 and the collector 100 and the radiator 200, and on the other hand, it can ensure the connection tightness between the first connecting pipe 400 and the collector 100 and the radiator 200.
[0035] Optionally, the two ends of the second connecting pipe 500 are respectively welded to the collector 100 and the radiator 200. Thus, on the one hand, it can improve the connection stability between the second connecting pipe 500 and the collector 100 and the radiator 200, and on the other hand, it can ensure the connection tightness between the second connecting pipe 500 and the collector 100 and the radiator 200.
[0036] Optionally, the circulation pump 300 is arranged on the first connecting pipe 400. Of course, in an alternative embodiment, the circulation pump 300 can also be arranged on the second connecting pipe 500. The specific position of the circulation pump 300 can be selected according to actual needs.
[0037] In some specific embodiments, a control valve is further provided on the first connecting pipe 400 and / or the second connecting pipe 500. It can be understood that during the actual working process, the control of the liquid circuit is achieved by adjusting the on / off state of the control valve, so as to cool the energy storage system according to actual needs. In some embodiments, a control valve is provided on the first connecting pipe 400; in some embodiments, a control valve is provided on the second connecting pipe 500; in some embodiments, control valves are provided on both the first connecting pipe 400 and the second connecting pipe 500.
[0038] In some specific embodiments, both the first connecting pipe 400 and the second connecting pipe 500 include an above-ground pipeline and an underground pipeline. The above-ground pipeline and the underground pipeline are arranged at an angle. The above-ground pipeline is connected to the liquid chamber, and the underground pipeline is connected to the heat dissipation chamber. It can be understood that due to the existence of the underground pipeline, the entire radiator 200 can be buried at a deeper position, which is beneficial to the heat dissipation of the radiator 200.
[0039] It should be added that in the embodiments of the present invention, the shapes and laying methods of the first connecting pipe 400 and the second connecting pipe 500 can be selected according to the actual structure of the energy storage system and the environment where the energy storage system is located. The specific structures of the first connecting pipe 400 and the second connecting pipe 500 are not limited herein.
[0040] In some embodiments, the material of the collector 100 is metal. It can be understood that metal has good thermal conductivity. Using metal to manufacture the collector 100 can quickly transfer the heat generated during the operation of the energy storage system to the collector 100, which is beneficial to improving the heat dissipation efficiency of the energy storage system. In the embodiments of the present invention, the specific type of metal selected for the collector 100 can be selected according to actual needs. In addition, in other embodiments of the present invention, the collector 100 can also be manufactured using materials with good thermal conductivity other than metal.
[0041] In some embodiments, the material of the radiator 200 is metal. It can be understood that metal has good thermal conductivity. Using metal to manufacture the radiator 200 can quickly transfer the heat to the ground, which is beneficial to improving the heat dissipation efficiency of the energy storage system. In the embodiments of the present invention, the specific type of metal selected for the radiator 200 can be selected according to actual needs. In addition, in other embodiments of the present invention, the collector 100 can also be manufactured using materials with good thermal conductivity other than metal.
[0042] In some embodiments, such as Figure 3As shown, there are multiple collectors 100, and each collector 100 corresponds to one battery of the energy storage system. It can be understood that, usually, multiple batteries can be set in an energy storage system, and each battery corresponds to one collector 100. During the actual working process, each battery can be cooled by a collector 100, ensuring good temperature uniformity of multiple batteries in the energy storage system and better avoiding the phenomenon of thermal runaway in the energy storage system.
[0043] In some embodiments, as Figure 4 shown, there are multiple radiators 200, and the multiple radiators 200 are respectively connected to the collectors 100. It can be understood that by using multiple radiators 200 to dissipate heat, the heat carried by the liquid can be quickly dissipated into the ground, which is beneficial to improving the cooling efficiency of the energy storage system.
