[0009] As a preferred technical solution, the sunshade is designed with an arc-shaped structure.

[0010] As a preferred technical solution, the liquid outlet pipe and the liquid inlet pipe are arranged in parallel, one above the other.

[0011] As a preferred technical solution, the circulation pipe is located at the highest point of the annular cooling chamber.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure, the coolant discharged from the industrial chiller can be injected into the annular cooling chamber through the inlet pipe, and as the coolant level rises, it can fully cover the inner tank and absorb heat quickly.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an industrial chiller for a hydrogen station, comprising an industrial chiller 1 for cooling a hydrogen tank 2. The inner liner of the hydrogen tank 2 has a first annular groove on its outer ring, and the outer shell of the hydrogen pipe has a second annular groove on its inner cavity. The first annular groove and the second annular groove combine to form an annular cooling chamber 10. Multiple bases 3 are installed on the hydrogen tank 2, and an inlet pipe 4 communicating with the annular cooling chamber 10 is installed between the bases 3. An outlet pipe 5 communicating with the annular cooling chamber 10 is provided on the side of the hydrogen pipe away from the base 3. One end of the inlet pipe 4 is bent and communicates with the outlet end of the industrial chiller 1, and the other end of the outlet pipe 5 is bent and communicates with the inlet end of the industrial chiller 1. A sunshade 6 is provided on the outside of the hydrogen tank 2.

[0020] In this embodiment, a liquid injection pipe 11 is vertically installed on a section of the liquid inlet pipe 4 inside the base 3, and the other end of the liquid injection pipe 11 extends into the annular cooling chamber 10. Multiple circulation pipes 12 are installed on one side of the liquid outlet pipe 5, and the other end of the circulation pipes 12 extends into the annular cooling chamber 10.

[0021] In this embodiment, multiple support frames 7 are installed on the inner side of the sunshade 6. Each support frame 7 is sleeved on the liquid outlet pipe 5. Both ends of the support frame 7 are extended to form a placement part, which is placed on the hydrogen tank 2. Multiple first screw holes are provided on the support frames 7 on both sides. Second screw holes are provided on the outer wall surface of the liquid outlet pipe 5 opposite to the first screw holes. Bolts 8 are threaded into the corresponding first screw holes and second screw holes.

[0022] In this embodiment, a plurality of positioning rings 9 are installed on the liquid outlet pipe 5, and the opposite surfaces of the positioning rings 9 are set to abut against the opposite end surfaces of the support frame 7. During the installation of the sunshade, the support frame can be directly fitted onto the liquid outlet pipe, while the outermost support frame abuts against the positioning ring. After rotating the bolts, the sunshade can be fixed onto the liquid outlet pipe. The positioning ring can axially position the sunshade, preventing axial movement.

[0023] In this embodiment, the sunshade 6 is arranged in an arc shape, which can cover the upper part of the hydrogen tank and avoid direct sunlight.

[0024] In this embodiment, the liquid outlet pipe 5 and the liquid inlet pipe 4 are arranged in parallel, one above the other; the circulation pipe 12 is located at the highest point of the annular cooling chamber 10, so that the water level can be discharged smoothly only after the inner tank is submerged, thereby fully cooling the inner tank.

[0025] The industrial chiller injects coolant into the annular cooling chamber through the inlet and injection pipes. As the coolant continues to enter, it envelops the inner liner of the hydrogen tank. As the coolant continues to flow in, the inner liner is submerged. After the water level rises again, the coolant is discharged from the circulation pipe and flows back into the industrial chiller through the outlet pipe. This submersion method provides efficient and thorough cooling of the hydrogen tank, avoiding the dangers caused by high temperatures. The upper part of the hydrogen pipe is equipped with a sunshade to cover it. The sunshade can effectively block sunlight, avoid the temperature rise caused by exposure to sunlight, and increase safety. The sunshade is also easy to install and remove.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
