Technical Field

[0001] This application relates to the field of modular data center building technology, and more particularly to a ventilation mechanism for modular buildings. Background Technology

[0020] The beneficial effects of this application are:

[0021] 1. This ventilation mechanism for modular buildings, by setting up a low-level air inlet, a high-level air inlet, an air cavity, and a high-level air outlet, delivers air into the air cavity through the low-level and high-level air inlets, and then exhausts the air from the air cavity through the high-level air outlet. It utilizes the heat generated by the roof panels of the modular building, as well as the heat generated by the operation of outdoor equipment and air conditioning units, to create thermal pressure, which promotes the rapid flow of hot air to the upper atmosphere. This avoids the problem of high energy consumption in traditional modular buildings when used in high-temperature environments due to the lack of a roof ventilation design specifically optimized for the characteristics of modular buildings, which easily leads to the heat island effect. This improves the practicality of the mechanism.

[0022] 2. This ventilation mechanism for modular buildings, by setting a limiting frame, a fixing frame and a filter screen, uses the limiting frame to limit the fixing frame, the fixing frame to fix the filter screen, and the filter screen to filter impurities in the air, avoiding the problem of traditional modular buildings being unable to filter impurities in the air, thus improving practicality.
