[0031] Example:

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment illustrates a liquid-cooled immersion tank for accommodating and cooling energy storage batteries. The liquid-cooled immersion tank includes a tank body 100 and a tank door 200. The tank door 200 is disposed on the tank body and can open or close the opening. The tank body 100 has a cavity with an opening 110, providing space for installing energy storage batteries. During use, the cavity is filled with cooling medium to submerge the energy storage batteries placed within.

[0033] The door 200 is detachably mounted on the opening 110 of the silo body 100. The plurality of fasteners 300 are arranged circumferentially around the door 200 and connected between the door 200 and the silo body 100. The plurality of fasteners 300 arranged circumferentially around the door 200 tightly connect the door 200 to the opening of the silo body 100, and a sealing structure is provided between the door 200 and the opening of the silo body 100 to improve the airtightness of the cavity.

[0034] Specifically, a first sealing member 410 is provided between the warehouse door 200 and the warehouse body 100 and surrounds the exterior of the warehouse opening 110 .

[0035] At the same time, the sealing portion 211 is provided with a second sealing member 420 between the circumferential side surface around the opening direction of the port 110 and the surface of the cavity for sealing the two when the port door is closed. The port door 200 is provided with a sealing portion 211 that can be embedded in the port 110. When the port door 200 is fastened to the port 110, the sealing portion 211 can be embedded in the port 110, and the circumferential side surface around the opening direction of the port 110 of the sealing portion 211 is close to the surface of the cavity, and the gap between the two is completely filled and sealed by the second sealing member 420. A double sealing structure is formed between the port door 200 and the port 110 of the port body 100 by the first sealing member 410 and the second sealing member 420, thereby improving the sealing effect of the port door 200 and the airtightness of the cavity.

[0036] In particular, because the cavity surface at the port opening 110 and the surface of the port opening 110 facing the door 200 are generally perpendicular to each other, the circumferential surface of the sealing portion 211 surrounding the opening of the port opening 110 and the surface of the door 200 facing the port opening 110 are also generally perpendicular to each other. Therefore, the first sealing member 410 and the second sealing member 420 are respectively provided on two nearly perpendicular sealing surfaces, which greatly improves the sealing effect compared to the method of providing two inner and outer sealing members on a single sealing surface.

[0037] In some embodiments, the sealing portion 211 is provided with a second sealing groove 212 on one of the circumferential side surface surrounding the opening direction of the port opening 110 and the surface of the cavity, and the second sealing member 420 is disposed in the second sealing groove 212. It is readily understood that the second sealing groove 212 can be provided on the circumferential side surface of the sealing portion 211 or on the surface of the cavity located at the port opening 110.

[0038] In some embodiments, the second sealing member 420 has an arc-shaped sealing surface 421. Figure 4 In the embodiment, the second sealing member 420 is an O-ring. The O-ring is placed on the circumferential surface of the sealing portion 211. Usually, the circumference of the O-ring is slightly smaller than the circumference of the sealing portion 211, so that the O-ring can be tightened on the circumferential surface of the sealing portion 211 after being placed on the circumferential surface. With the axis of the O-ring as the center, the O-ring has relative (radially) inner and outer side surfaces. The inner side of the O-ring is the part that contacts the circumferential surface of the sealing portion 211, and the outer side of the O-ring is the part that can contact the cavity surface at the port 110 during sealing.

[0039] The arcuate sealing surface 421 includes at least an outer side surface and an inner side surface of the sealing ring. In this embodiment, the cross-section of the arcuate sealing surface 421 on the O-ring is circular. In a cross-section taken along the axial direction of the second sealing member 420, the outer side surface of the arcuate sealing surface 421 faces away from the axis of the second sealing member 420.

[0040] In addition, in some alternative embodiments, the second sealing member 420 may also use a D-type sealing ring instead of an O-type sealing ring. Figure 5 As shown, a D-shaped sealing ring is provided in the second sealing groove 212 on the peripheral surface of the sealing portion 211 , and the outer side surface of the arcuate sealing surface 421 of the D-shaped sealing ring faces away from the axis of the second sealing member 420 .

[0041] In some embodiments, the second sealing groove 212 is a circular groove or a rectangular groove. In this embodiment, the second sealing groove 212 disposed at the opening 110 of the chamber body 100 is used as an example for illustration. The depth of the second sealing groove 212 is less than the cross-sectional diameter of the second sealing member 420. Thus, when the second sealing member 420 is disposed within the second sealing groove 212, the outer portion of the second sealing member 420 is exposed from the opening of the second sealing groove 212, thereby forming a close contact with the cavity surface at the opening 110 and forming a seal.

[0042] In some embodiments, a first sealing groove 130 is provided on at least one of the surface of the door 200 facing the port opening 110 and the surface of the port opening 110 facing the door 200. Similarly, the first sealing groove 130 also surrounds the exterior of the port opening 110. The first sealing member 410 is disposed within the first sealing groove 130. When the door 200 is fastened to the port opening 110 of the silo body 100 by the fastener 300, the first sealing member 410 between the two may be squeezed and deformed. By providing a first sealing groove 130 of predetermined dimensions, the deformation of the first sealing member 410 can be constrained, maintaining a corresponding pressure on its sealing surface, thereby meeting airtightness requirements. Furthermore, since the first sealing member 410 is partially located within the first sealing groove 130, the sidewalls of the sealing groove can provide support to the first sealing member 410 after contact with the exterior surface of the first sealing member 410, preventing the first sealing member 410 from deforming outward and increasing its perimeter.

[0043] It is easy to understand that the first sealing groove 130 can be provided on the surface of the compartment door 200 facing the compartment opening 110, or on the surface of the compartment opening 110 facing the compartment door 200, or two first sealing grooves 130 can be provided at the same time, one on the surface of the compartment door 200 facing the compartment opening 110, and the other on the surface of the compartment opening 110 facing the compartment door 200, with the two first sealing grooves 130 facing each other and each accommodating a portion of the first sealing member 410. When two sealing grooves facing each other are provided on two surfaces, the groove depth of each sealing groove should be reduced accordingly.

[0044] In some embodiments, the first seal 410 is a flat gasket seal. The first sealing groove 130 is a rectangular groove, and the width of the flat gasket seal along its axial direction is greater than the groove depth of the rectangular groove. Since the warehouse door 200 is fastened to the warehouse opening 110 by multiple fasteners 300. After the first seal 410 adopts a flat gasket seal, its two sealing surfaces are two planes opposite to each other in the axial direction of the flat gasket seal. The plane on one side of the axial direction of the flat gasket seal is located in the first sealing groove 130 and fits the bottom surface of the groove, and the plane on the other side faces the warehouse door 200, and when the warehouse door 200 is fixed by the fasteners 300, it can fit tightly with the surface of the warehouse door 200 and form a seal. Since both side surfaces of the flat gasket seal are flat, the warehouse door 200 can be evenly stressed after being fastened, and local uneven stress can be avoided as much as possible.

[0045] In some embodiments, the angle between the surface of the door 200 facing the port opening 110 and the circumferential surface of the sealing portion 211 in the direction of the port opening 110 is 85° to 95°. It will be readily understood that the angle between the surface of the door 200 facing the port opening 110 and the circumferential surface of the sealing portion 211 in the direction of the port opening 110 is typically set to 90°, but considering factors such as processing technology, the angle may be set within a certain range.

[0046] In some embodiments, the silo body 100 is provided with an outer flange 120 on the outer wall of the silo opening 110. Multiple fasteners 300 are provided between the silo door 200 and the flange 120. These fasteners surround the first seal 410 and connect the edges of the silo door to the flange 120. These fasteners 300 can be universal threaded fasteners, allowing for uniform configuration and enhanced versatility.

[0047] In some embodiments, the door 200 includes a door panel and a door frame 210 disposed around the door panel. A surface of the door frame 210 forms the surface of the door 200 facing the hatch 110, and the sealing portion 211 is disposed around this surface of the door frame 210. The provision of the door frame 210 strengthens the strength of the door 200 on all sides, preventing local deformation due to insufficient strength after the door 200 is connected to the warehouse body 100 using multiple fasteners 300, thereby preventing a decrease in airtightness caused by local deformation.

[0048] In some embodiments, the door 200 is located on the periphery of the warehouse body 100, and the door frame 210 forms a seal with the door 200. The door panel is a transparent door panel. The door panel is sealed with the door frame 210. The door 200 is located on the periphery of the warehouse body 100 to facilitate loading and unloading of the energy storage battery. Furthermore, the transparent door panel allows for easy observation of the energy storage battery inside the warehouse body 100, providing timely information on the heat dissipation of the energy storage battery and the level of the cooling medium.

[0049] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are included within the scope of the claims.
