[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0033] Example 1:
[0034] like Figure 1 and Figure 3 As shown, the liquid-cooled dehumidification module in one embodiment of the present invention includes an inlet pipe 10, an outlet pipe 20, a turbulence pipe 30, an exhaust assembly 40, a drainage assembly 50, and a liquid-cooled unit 60.
[0035] The inlet pipe 10 and the outlet pipe 20 are directly or indirectly connected. When the inlet pipe 10 and the outlet pipe 20 are indirectly connected, a liquid cooling plate is provided between them. The liquid cooling unit 60 has at least one outlet and at least one inlet. The inlet pipe 10 is connected to the outlet of the liquid cooling unit 60, and the outlet pipe 20 is connected to the inlet of the liquid cooling unit 60. Preferably, both the inlet pipe 10 and the outlet pipe 20 are made of stainless steel.
[0036] like Figure 1 and Figure 4 As shown, a baffle pipe 30 is installed on a portion of the liquid inlet pipe 10. Preferably, the baffle pipe 30 is located at the end of the liquid inlet pipe 10 near the liquid outlet of the liquid cooler unit 60. A vent 31 is provided on the baffle pipe 30. When a cool condensate is introduced into the liquid inlet pipe 10 through the liquid cooler unit 60, condensation forms on the surface of the liquid inlet pipe 10 because the air temperature is higher than the condensate. The baffle pipe 30, located outside the liquid inlet pipe 10, can be used to collect this condensate. Based on this design, the liquid inlet pipe 10 and the liquid outlet pipe 20 not only serve as cooling elements, but the liquid inlet pipe 10 can also serve as a dehumidification element, thus eliminating the need for a separate dehumidification module to dehumidify the energy storage system's enclosure.
[0037] The evaporation pipe 30 has a first end a and a second end b arranged opposite to each other in the radial direction. In order to effectively drain the collected condensation, there is a height difference between the first end a and the second end b in the vertical direction. A drainage component 50 is provided on the evaporation pipe 30 at the lower end of the first end a and the second end b.
[0038] like Figure 1 and Figure 2As shown, the drainage assembly 50 includes a drainage pipe 51 and a drainage channel 52. The drainage pipe 51 is connected to the lower end of the baffle pipe 30. The drainage channel 52 is located below the baffle pipe 30 and corresponds to the outlet end of the drainage pipe 51.
[0039] It is understood that when the liquid-cooled dehumidification module of this embodiment is installed in the energy storage system, in order to prevent the condensation from affecting the components inside the energy storage system, an additional drainage pipe C can be provided on the drainage tank 52. The additional drainage pipe C can extend directly out of the energy storage system to discharge the condensation in the drainage tank 52 directly into the energy storage system.
[0040] To further improve dehumidification efficiency, an exhaust assembly 40 is also provided in this embodiment. The exhaust assembly 40 includes an exhaust duct 41 connected to the baffle duct 30 and an exhaust device 42 acting on the exhaust duct 41. After the exhaust device 42 is operated, it allows external air to flow sequentially through the vent 31, the baffle duct 30, and the exhaust duct 41 before being discharged from the exhaust device 42.
[0041] The turbulence duct 30 includes a first side and a second side that are arranged opposite to each other. The vent 31 is arranged on the first side, the exhaust duct 41 is arranged on the second side, and the exhaust duct 41 extends in a direction away from the second side. The exhaust device 42 is arranged at the end of the exhaust duct 41 away from the turbulence duct 30.
[0042] In this embodiment, by further defining the relative positions of the exhaust duct 41 and the exhaust device 42 to the baffle duct 30, the direction of air circulation can be controlled. Therefore, when the liquid-cooled dehumidification module of this embodiment is installed in the energy storage system, the rapid air circulation within the energy storage system can be controlled in a directional manner based on the placement position of the battery pack in the energy storage system and the temperature difference inside the enclosure caused by the placement position of the battery pack. This further improves the dehumidification efficiency and ensures that the air flows through the battery pack as much as possible, providing both liquid cooling and air cooling to the battery pack.
[0043] For example, such as Figure 1 and Figure 5 As shown, the liquid inlet pipe 10 may include a liquid inlet section 11 extending in a first direction. The liquid inlet section 11 is located near the liquid outlet of the liquid chiller 60. A baffle pipe 30 may be fitted onto the liquid inlet section 11 and also extends in the first direction. Since the condensate exiting the liquid chiller 60 has a low temperature, it is more likely to condense into condensate when air flows through the liquid inlet section 11 near the liquid outlet of the liquid chiller 60. Therefore, preferably, the baffle pipe 30 is fitted onto the liquid inlet section 11 to collect the condensate.
[0044] The exhaust duct 41 extends in the second direction. The first side where the vent 31 is located on the baffle duct 30 and the second side where the exhaust duct 41 is located are two opposite sides in the second direction, which can increase the time for air to contact the liquid inlet section 11. In conjunction with the fact that the exhaust duct 41 extends in the second direction away from the first side of the baffle duct 30, it can cause a certain directional flow of external air in the second direction. Of course, the vent 31 can also be located on other sides of the baffle duct 30. There can be multiple vents 31, and multiple vents 31 can be arranged in an array on the baffle duct 30.
[0045] The exhaust device 42 is located at the end of the exhaust duct 41 away from the turbulence pipe 30 and is configured to exhaust air upwards in a third direction after operation. The exhaust device 42 is preferably a dehumidifying exhaust fan or dehumidifying exhaust fan with an air volume of 70 CFM. The second direction intersects or is perpendicular to the first direction, and the third direction intersects or is perpendicular to the plane formed by the first and second directions.
[0046] Preferably, the second direction is perpendicular to the first direction, and the third direction is perpendicular to the plane formed by the first and second directions.
[0047] The placement of the exhaust device 42 and its outlet orientation in the third direction allow air to circulate in the second direction. When the liquid-cooled dehumidification module of this embodiment is installed in the energy storage system, the inlet section of the liquid inlet pipe 10 is located near the interior of the energy storage system and extends along the length of the system. The exhaust pipe 41 extends along the width of the system, and the exhaust device 42 is located near the exterior (where the door is) within the energy storage system. This creates an air circulation from the inside out, allowing the hot air near the interior of the energy storage system to be quickly dehumidified and cooled. Simultaneously, the exhaust pipe 1 is extended to the battery compartment 1 (e.g., Figure 3 As shown, the exhaust fan 42 is located at the bottom of the battery compartment, which allows the rapidly dehumidified and cooled air to circulate between the battery packs inside the battery compartment, thereby cooling the battery packs.
[0048] Furthermore, the exhaust assembly 40 may include multiple exhaust ducts 41 and multiple exhaust devices 42, wherein one exhaust duct 41 may correspond to one or more exhaust devices 42. The multiple exhaust ducts 41 are arranged in an array along the first direction on the baffle duct 30.
[0049] To prevent further heat release, the liquid outlet pipe 20 is covered with a heat insulation layer (not shown in the figure).
[0050] In this embodiment, the liquid-cooled dehumidification module utilizes the low outlet water temperature (typically ≤18℃) of the liquid-cooled unit 60. Instead of thermal insulation protection for the inlet pipe 10, it leverages the fact that the temperature of the condensate flowing through the stainless steel inlet pipe 10 (typically ≤18℃) is lower than the air temperature inside the energy storage system (typically above 25℃). This allows water molecules in the air to exchange heat with the condensate, transforming from a gaseous state to a liquid state and adhering to the surface of the inlet pipe 10. When a certain amount of condensation is reached, it drips into the baffle pipe 30 and is then discharged through the drain pipe 51. When the air humidity is high, water molecules in the air condense more easily on the surface of the inlet pipe 10. Simultaneously, the exhaust assembly 40 draws air into the baffle pipe 30, ensuring continuous airflow through the inlet pipe 10 during air circulation, achieving the same effect as a dehumidifier.
[0051] Example 2:
[0052] The energy storage system in one embodiment of this utility model includes a housing, a battery module located inside the housing, and a liquid-cooled dehumidification module as described in Embodiment 1.
[0053] The battery module includes battery compartment 1 (e.g., Figure 3 As shown, at least one battery pack is installed in the battery compartment. The battery pack is equipped with a liquid cooling plate, which includes an inlet and an outlet. The inlet and outlet of the liquid cooling plate are respectively connected to an inlet pipe and an outlet pipe.
[0054] The inlet and outlet pipes are located inside the tank. The inlet pipe includes an inlet section that extends along the length of the tank. A baffle is installed on the inlet section.
[0055] The ventilation assembly extends along the width of the housing, and part of the ventilation assembly extends into the battery compartment of the battery module. The ventilation device in the ventilation assembly is installed on the ventilation duct inside the battery compartment.
[0056] In this second embodiment, the liquid-cooled dehumidification module not only dehumidifies the energy storage system's enclosure but also utilizes the placement of the exhaust fan to allow the generated airflow to pass through the battery pack located in the battery compartment, thereby cooling the battery pack. Combined with the liquid cooling of the battery pack via inlet and outlet pipes, the cooling effect is further enhanced. The generated airflow also further improves the dehumidification effect.
[0057] Compared with the prior art, the liquid-cooled dehumidification module and energy storage system of this utility model not only serve as a cooling element but also as a dehumidification element. The turbulence pipe not only serves to limit the directional circulation of air but also collects the condensation formed outside the liquid inlet pipe. It can dehumidify the energy storage system box without the need to install a separate dehumidification module. It has a simple structure, saves space, reduces costs, consumes less energy, and is easy to maintain.
[0058] The liquid-cooled dehumidification module and energy storage system of this invention, through the positional arrangement of the exhaust component relative to the turbulence pipe, enables directional air circulation. When applied to an energy storage system, it can more efficiently achieve dehumidification and cooling of the energy storage system's enclosure.
[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
