X, the invention name is "a heat dissipation system for a retaining structure", the priority of the Chinese application, the entire contents of which are incorporated by reference. Combined in this application. Technical field

The invention relates to the field of ground source heat dissipation, and in particular to a heat dissipation system for a building structure. Background technique

With the development of broadband network systems, large-capacity broadband book access devices need to be deployed to the street-side cabinets near residential areas to provide network services to residents. Broadband access equipment generates a large amount of heat during operation, so it is necessary to effectively dissipate the heat inside the cabinet in time to provide a suitable working environment temperature for the broadband access equipment. The heat dissipation system inside the cabinet is usually cooled by a fan. The fan generates noise when it is working. The heat of the device is higher, and the noise is more serious. Because street cabinets are often close to residential areas, excessive noise will affect residents' sleep and reduce the quality of life at night. Currently, the regulatory requirements for such noises in the world are becoming stricter. Therefore, low-noise and efficient heat dissipation must be adopted. At the same time, the size of the street cabinet needs to be compact, does not affect traffic, and is easy to arrange.

Referring to FIG. 1 , in the prior art, the heat dissipation system of the sealed cabinet 1 is installed in a sealed cabinet 1 isolated from the external environment. The sealed cabinet 1 is installed on the ground 7 through the cement base 6 in the sealed cabinet. A fan 2 is provided in the upper portion of the communication device 3. The wall surface 5 of the hermetic cabinet 1 may have a pleated structure to increase the surface area.

When the communication device 3 in the sealed cabinet 1 needs to dissipate heat, the fluid generated by the communication device 3 in the sealed cabinet 1 is enhanced by the action of the fan 2, and the internal circulating airflow is formed in the closed cabinet 1 by natural convection. Thus, the heat generated by the communication device 3 is transmitted to the wall surface 5 of the closed cabinet 1 by convection, heat conduction, radiation, etc., and then the heat generated by the communication device 3 is transferred to the external environment through the wall surface 5 of the sealed cabinet 1.

In the process of implementing the present invention, the inventors found that at least the following problems exist in the prior art:

Since the heat dissipation capability of the sealed cabinet 1 is restricted by the temperature of the external ambient air, when the external ambient temperature of the sealed cabinet 1 is higher than the temperature inside the sealed cabinet 1, the heat generated by the communication device 1 is difficult to pass through the convection, heat conduction, and radiation. The wall 5 of the cabinet 1 is transferred to the external environment. Summary of the invention
