Heat dissipation structure and machine cabinet

Abstract

Embodiments of the invention disclose a heat dissipation structure. The heat dissipation structure comprises a shell and a partition plate, wherein the shell is of a full-sealing structure and comprises a top and a bottom; the partition plate is fixed to the interior of the shell; the partition plate comprises a side plate and a bottom plate, and the side plate extends from the top to the bottom;a first air duct is formed between the side plate and the shell; the bottom plate is located at the bottom, and a second air duct is formed between the bottom plate and the shell; one side, deviatingfrom the first air duct and the second air duct, of the partition plate is an accommodating space, wherein the accommodating space is used for accommodating a heating element; an air inlet is formed in a position, close to the top, of the side plate; an air outlet is formed in the bottom plate; a fan is arranged at the air inlet, wherein the fan is used for pumping hot air into the first air duct;and the hot air passes through the first air duct and the second air duct, and the shell transmits the heat of the hot air to the outer side, so that the temperature of the hot air is reduced and thehot air is changed into cold air to flow into the accommodating space from the air outlet. The embodiments of the invention further disclose a buried machine cabinet. By adopting the heat dissipationstructure provided by the embodiments of the invention, the problems of soaking and salt mist corrosion are solved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of cabinets, in particular to a heat dissipation structure of buried cabinets. Background technique [0002] As a brand-new form of base station, buried base stations have attracted the attention of the three major operators in the Chinese market. The buried base station is to place the base station underground and bury it in the soil. The heat dissipation capability of the buried base station determines the configuration, heat consumption, and power of the base station, thereby determining the market competitiveness of the product. [0003] Usually, the setting of the buried base station is: the cabinet is buried underground, and the heat inside the cabinet is exported to above the ground through the cold and hot air pipes. The structure of the hot and cold air ducts extending from the ground to the surface is complex and expensive, and when the cabinet is connected to the air, it cann...

AI Technical Summary

Problems solved by technology

The structure of the hot and cold air pipes extending from the ground to the surface is complex and expensive, and when the cabinet is connected to the air, it cannot achieve high-level waterproof performance, and the cabinet has the risk of water immersion and salt spray corrosion
