Roof heat-dissipating device

Abstract

The invention relates to a roof heat-dissipating device which comprises an outer hood erected and mounted on a roof, a barrier plate arranged at one end of the outer hood and a fan unit arranged at the barrier plate, wherein the outer hood and the barrier plate are combined to form a hollow space part, so that a housing of the fan unit can be accommodated in the space part. The barrier plate is composed of an air outlet hole communicating to the space part, a fixed groove located in the periphery of the air outlet hole and a screw hole formed between the fixed groove and the air outlet hole. The fan unit is composed of a substrate arranged at the barrier plate, a housing arranged on another side surface of the substrate, a hollow accommodation chamber composed of the housing the substrate,a joint part formed by stretching outward from the substrate in a protruding manner, an exhaust hole penetrating the joint part and communicating to the accommodation chamber, an air inlet hole located in the housing and communicating to the accommodation chamber, a motor arranged on the housing and a fan blade arranged at an axle rod of the motor and accommodated in the accommodation chamber.

Description

technical field [0001] The invention relates to a roof cooling device, in particular to a roof cooling device which can be directly disassembled, installed and maintained on the roof. Background technique [0002] Generally, the factory building of the iron house type will be about 2 to 3 stories high when it is built. In order to prevent the iron roof from being exposed to the sun for a long time and cause hot air to concentrate in the iron house, some operators have developed a heat dissipation structure for the iron roof, such as figure 1 As shown, it mainly provides a vent 10 at an appropriate place on the roof corrugated board 1, so that the hollow cylindrical body 11 can be assembled on the roof corrugated board 1; The shaft portion 120 of the fixed bracket 12 can be sleeved with a shaft 13 (that is, it is best to interpose a bearing between the shaft portion 120 and the shaft 13, not shown in the figure), and the other end of the shaft 13 is sleeved On the fixed pla...

AI Technical Summary

Problems solved by technology

[0004] When the exhaust motor 17 suspended at the roof corrugated board 1 with a height of about 2 to 3 floors breaks down, it is necessary to ask a professional to replace and repair it, and it is necessary to cooperate with the schedule of the professional to repair it. The required exhaust motor 17 and support 16 have a certain volume and weight. In addition, the installation location is under the roof (i.e. without any support), which often requires multiple people to disassemble, repair or replace at the same time. As a result, it will not only make the time of stopping the ventilation longer, but also cause the air in the house to overheat, causing heat stroke or dehydration of the workers inside, and at the same time, it will also make the maintenance personnel have no safe and stable standing position, resulting in It is not easy to apply force to disassemble and install, and the required maintenance time and labor cost are greatly increased
