Description

Technical Field

[0001] This utility model belongs to the technical field of radiant cooling cabinet structure, and in particular relates to an outdoor cabinet with radiant cooling function. Background Technology

[0002] When the sunlight is strong, the internal temperature of various outdoor server racks rises quickly. In order to keep the internal temperature of the rack within a suitable range, an air conditioning system is usually required. However, such racks with air conditioning systems are not only more expensive to manufacture, but also increase energy consumption.

[0003] Radiative cooling, as a passive cooling technology, can exchange heat with outer space through atmospheric windows without consuming energy, resulting in a surface temperature of the radiative cooling material that is lower than the ambient temperature. Existing technologies include using a radiative cooling layer on the outer wall of the server rack to lower the surface temperature below ambient temperature, thereby slowing down the temperature rise inside the rack. However, this simple method of installing a radiative cooling layer only lowers the rack temperature to ambient temperature and does not effectively dissipate heat from inside the rack. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an outdoor cabinet with radiative cooling function, which can automatically reduce the internal temperature without consuming energy.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed:

[0006] An outdoor cabinet with radiative cooling function includes: cabinet body, cabinet door and top cover.

[0007] Both the surface of the top cover and the outer wall of the cabinet are equipped with a radiant cooling layer;

[0008] The top cover has ventilation holes on its periphery, which are connected to the inside of the cabinet and located on the outside of the cabinet.

[0009] The lower edge of the radiant cooling layer on the outer wall of the cabinet is at a predetermined distance from the bottom surface of the cabinet.

[0010] The bottom of the cabinet has ventilation holes, which are covered with ventilation and dustproof panels.

[0011] The cabinet is equipped with support legs at the bottom to support the cabinet.

[0012] The beneficial effects of this utility model are as follows: by setting up a radiant cooling layer, the temperature inside the cabinet can be lower than the ambient temperature; and the airflow inside the cabinet can automatically circulate, which can carry away the heat inside the cabinet during the airflow circulation process, thereby achieving the purpose of heat dissipation; the overall structure of the solution is simple, which can not only improve the heat dissipation effect of the cabinet, but also requires no energy consumption.

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, an outdoor cabinet with radiant cooling function includes: cabinet body 1, cabinet door 2, and top cover 3.

[0021] Both the surface of the top cover 3 and the outer wall of the cabinet 1 are provided with a radiant cooling layer.

[0022] The top cover 3 has an exhaust hole 31 on its periphery. The exhaust hole 31 is connected to the inside of the cabinet 1 and is located on the outside of the cabinet 1.

[0023] The lower edge of the radiant cooling layer on the outer wall of cabinet 1 is at a predetermined distance from the bottom surface of cabinet 1. This can also be understood as the radiant cooling layer on the outer wall of cabinet 1 only covering the middle and upper sections of cabinet 1, while the lower section of the outer wall of cabinet 1 is not equipped with a radiant cooling layer.

[0024] The bottom surface of the cabinet 1 has ventilation holes 11, and ventilation and dustproof panels 12 are laid on the ventilation holes 11. The ventilation and dustproof panels 12 are made of cotton fabric or sponge.

[0025] The bottom of the cabinet 1 is provided with support legs 13 to support the cabinet 1, so that there is a predetermined gap between the bottom surface of the cabinet 1 and the installation ground to facilitate gas circulation.

[0026] In this embodiment, by setting radiant cooling layers on the surface of the top cover 3 and the middle and upper sections of the outer wall of the cabinet 1, the temperature inside the cabinet can be lower than the ambient temperature, thus slowing down the temperature rise inside the cabinet. In this solution, the outer wall of the cabinet 1 is only set with radiant cooling layers in the middle and upper sections, while the lower section of the cabinet 1 is not set with radiant cooling layers. The purpose is to make the temperature at the bottom of the cabinet higher than the temperature at the top of the cabinet. Because the density of gas in a high-temperature environment is lower than that in a low-temperature environment, the gas at the bottom of the cabinet will automatically rise, then pass through the top of the cabinet 1 and be discharged from the exhaust port 31. After the gas at the bottom of the cabinet rises, it will automatically draw in the gas between the cabinet and the ground and enter the cabinet through the vent 11 to balance the air pressure inside and outside the cabinet. Through the above method, the airflow inside the cabinet will automatically circulate. During the airflow circulation process, the heat inside the cabinet can be carried out, thereby achieving the purpose of heat dissipation. The overall structure of the solution is simple, which not only improves the heat dissipation effect of the cabinet, but also requires no energy consumption.

[0027] Preferably, the outer wall of the cabinet door 2 is provided with a radiative cooling layer, and the lower edge of the radiative cooling layer is at a predetermined distance from the bottom edge of the cabinet door 2, so as to further reduce the temperature inside the cabinet and increase the temperature difference between the bottom and top of the cabinet, thereby improving the gas flow efficiency.

[0028] Preferably, the radiative cooling layer is a radiative cooling film or a radiative cooling coating. When the radiative cooling layer is a radiative cooling film, it is applied to the surface of the top cover 3 and the outer wall of the cabinet 1 by adhesive bonding. When the radiative cooling layer is a radiative cooling coating, it is applied to the surface of the top cover 3 and the outer wall of the cabinet 1 by spraying.

[0029] Preferred, such as Figure 1 As shown, a fan 4 for airflow above the cabinet is installed on the ventilation and dustproof plate 12. When the ambient temperature is too high, the fan 4 can blow air upwards to improve the circulation efficiency of the airflow inside the cabinet 1 and increase the heat dissipation effect.

[0030] Preferred, such as Figure 3 , Figure 4 As shown, the bottom surface of the top cover 3 is provided with a heat insulation layer 32 to further reduce the impact of external light on the internal temperature of the cabinet.

[0031] Preferred, such as Figure 4 As shown, the top cover 3 has an inwardly extending inner buckle plate 33 on its periphery. The inner buckle plate 33 is located on the outside of the cabinet 1, and the edge of the inner buckle plate 33 is flush with the wall of the cabinet 1. The inner buckle plate 33 is lower than the top surface of the cabinet 1. The exhaust hole 31 is opened on the inner buckle plate 33. This structural design makes the exhaust hole 31 located below the periphery of the top cover 3, which can effectively prevent rainwater from entering the cabinet 1. Moreover, with this structural design, the airflow discharged from the exhaust hole 31 will sweep across the outer wall of the cabinet 1, thereby achieving the purpose of heat dissipation of the outer wall of the cabinet 1.

[0032] Preferred, such as Figure 4 As shown, the top of the cabinet 1 is provided with a guide plate 5. The guide plate 5 is inclined towards the outer side of the cabinet 1, and the end of the guide plate 5 is bent inward towards the buckle plate 33. By setting the guide plate 5, the rising airflow can flow quickly to the four sides of the cabinet 1, and after passing through the bent structure at the end of the guide plate 5, the airflow is guided into the exhaust hole 31, so as to improve the air circulation speed inside the cabinet and thus improve the heat dissipation effect of the cabinet.

[0033] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
