AI Technical Summary
Existing security cabins lack internal cooling capabilities, resulting in poor comfort for personnel in the event of a fire, and conventional cooling methods cannot be used when isolated from the outside world.
An internal circulation cooling device is adopted, including a heat dissipation unit and a storage tank. The cooling medium circulates in the medium pipeline to cool the interior of the cabin, and the fire resistance and heat insulation capabilities are enhanced by the combination of a metal shell and a frame structure.
It achieves effective cooling inside the cabin while isolated from the outside world, ensuring the comfort and safety of personnel and extending the service life of the security cabin.

Abstract
Claims
1. A security cabin based on circulating cooling medium, characterized in that, Includes a cabin and an internal circulation cooling device installed inside the cabin; The internal circulation cooling device includes a heat dissipation unit and a storage tank; The storage tank is used to store the cooling medium. A medium pipeline is provided between the heat dissipation unit and the storage tank, and a pump body is provided corresponding to the medium pipeline. The cooling medium is pumped into the heat dissipation unit through the pump body, and exchanges heat with the internal environment of the cabin in the heat dissipation unit, thereby achieving the cooling of the internal environment of the cabin.
2. The cooling medium circulation-based cooling shelter for security protection according to claim 1, wherein, The cabin includes an outer shell and a frame disposed inside the outer shell. The frame is fitted to the inner wall of the outer shell and is used to support the outer shell.
3. The cooling medium circulation-based cooling shelter for security protection according to claim 2, wherein, The heat dissipation unit and / or the storage box are respectively fixedly connected to the frame; And / or, Constraints are provided corresponding to the medium pipeline. Multiple constraint members are spaced apart along the axial direction of the medium pipeline to achieve a tight connection between the medium pipeline and the skeleton.
4. The cooling medium circulation-based cooling shelter for security protection according to claim 2 or 3, wherein, The frame is provided with a skin on the side away from the outer shell, and a sandwich space is formed between the skin and the outer shell, which can accommodate the internal circulation cooling device.
5. The cooling medium circulation-based cooling-type security cabin according to claim 2 or 3, wherein The outer casing includes a metal shell, fire-retardant paint applied to the outer wall of the metal shell, and a heat-insulating portion applied to the inner wall of the metal shell.
6. The cooling medium circulation-based cooling shelter for security protection according to claim 5, wherein, The heat insulation part includes a multi-layer aerogel heat insulation layer and a fiberglass cloth stacked sequentially from the side closest to the metal shell to the other side.
7. The cooling medium circulation-based cooling shelter according to any one of claims 1 to 3, wherein, The cooling unit includes a heat exchange section, heat dissipation components, and a cooling fan. The heat exchange section has a medium flow channel, and both ends of the medium flow channel are connected to the medium pipeline, so that the cooling medium flows in the medium flow channel. The heat dissipation component includes a substrate and heat-conducting parts and heat dissipation fins disposed on both sides of the substrate. The heat-conducting parts abut against the heat exchange parts, and the cooling fan is aligned with the heat dissipation fins.
8. The cooling medium circulation-based cooling shelter according to claim 7, wherein, The medium flow channel is a "U"-shaped channel, or is formed by multiple "U"-shaped channels connected in series; And / or, Thermal grease is provided between the heat exchange section and the heat conduction section.
9. The security cabin based on cooling medium circulation cooling according to any one of claims 1 to 3, wherein, At least one media injection pipe is provided corresponding to the storage box. One end of the medium injection pipe is connected to the storage tank, and the other end is located in the cabin space, so as to complete the injection of cooling medium into the storage tank inside the cabin; And / or, One end of the medium injection pipe is connected to the storage tank, and the other end is connected to an interface on the cabin body to complete the filling of cooling medium from the outside. A sealing cap is provided corresponding to the interface.
10. The cooling medium circulation-based cooling shelter according to any one of claims 1 to 3, wherein, An emergency power supply is installed at the bottom of the cabin to power the internal circulation cooling device; And / or, The interior space of the cabin is also equipped with an oxygen supply device to supply oxygen to the interior space of the cabin.
