Description

Structure of built-in fan for building heat sink and its manufacturing method

The invention relates to a construction equipment, in particular to a structure of a built-in fan of a radiator cover of a building and a manufacturing method thereof.

In order to effectively exclude or dissipate the hot air in the building, many buildings will have an exhaust perforation at the top of the building, and a heat sink will be installed outside the hole of the exhaust perforation at the top of the building. The cover can be used to guide the hot air to the outside through the interior of the venting opening and the top venting top hole, and then the various rainproof water leakage guides or baffles are arranged inside the heat absorbing cover to avoid Rainwater falls into the interior of the building through the exhaust top hole and the exhaust vents of the building.

In the previously known construction, the inventors have thought of providing a fan inside the heat shield to accelerate the exhaust. However, it has been found that it is not difficult to install a fan inside the heat sink. However, the effect is limited in practice. The main reason is that the fan is mainly a pumping process, and the pumping process must simply pump the hot air in the building. In the process of fan pumping, it is not possible to extract air from other sources, otherwise it is easy to cause so-called "circulating negative pressure". If there is negative pressure in the cycle, the fan pumping process will continue to be sucked up due to "near end". Air to other sources can cause hot air in buildings that really need to be taken out.

From the foregoing, the fan must form a dense leak-proof measure with the exhaust perforation, and try to avoid the leakage. Therefore, if a fan is installed inside the heat-dissipating cover, the heat-dissipating cover is integrally installed in the hole of the exhaust perforation. The edge, because the fan is already inside the heat sink, it is impossible to prevent the fan and the exhaust perforation from leaking.

Furthermore, even if someone wants to use the fan first from the inside to the top of the building, it is usually necessary to set up an elevated structure inside the building, and installing the fan from the inside of the building must have a high construction risk.

In view of the problems of the prior art, the inventor believes that there should be a need to solve the previous problem, and a construction method is designed for this, that is, a method for manufacturing a built-in fan of a radiator cover of a building, the steps of which include at least one row at the top of a building. The air perforation is provided with a heat dissipation cover on the top of the building corresponding to the exhaust perforation, and a fan is disposed inside the heat dissipation cover, and the fan is stacked on the exhaust perforation in advance by the top of the building by the periphery. Above the hole edge, a gap-preventing edge is formed at the hole of the fan and the hole of the exhaust hole, and then the heat shield is assembled on the top of the building. In this way, firstly, it is superposed on the top of the hole of the exhaust perforation by the top construction of the building, so that the constructor can be constructed on the top of the building, which is relatively safe. And pre-stacked by the top of the building and stacked above the hole edge of the exhaust perforation, so that the fan installation work can be uncoupled from the heat sink cover and independently, contributing to the fan and the exhaust perforation. The hole-edge gap is constructed to form a gap-proof leak-proof edge, so as to avoid the air drawn from other sources during the pumping process, which causes "circulating negative pressure", so that the pumping process can simply pump the heat in the building. .

The structure, features, and embodiments of the present invention will be described in conjunction with the drawings.

Referring to the first figure, the present invention relates to a method for manufacturing a built-in fan of a building heat sink, the steps of which at least include providing an exhaust perforation (11) at a top (1) of a building.

Please refer to the third and fourth figures, and a heat shield (2) is arranged on the top (1) of the building corresponding to the exhaust perforation (11), and a fan (3) is arranged inside the heat shield (2). ).

Referring to the first and second figures, the fan (3) is superposed above the hole edge of the exhaust perforation (11) by the construction of the top (1) of the building in advance. A gap between the fan (3) and the hole edge of the exhaust perforation (11) is formed to form a gap leakage preventing edge (4), and then the heat shield (2) is assembled to the top (1) of the building.

At the same time, the present invention is also based on the same general invention, and forms a structure of a built-in fan of a building heat sink, including the exhaust perforation (11) at the top of the building (1), and the building corresponding to the exhaust perforation (11) The heat sink (2) is disposed on the top (1) of the object, and the fan (3) is disposed inside the heat shield (2), and the peripheral edge of the fan (3) and the hole of the exhaust hole (11) are provided with the connection Gap leakage prevention edge (4).

In this way, firstly, the top of the building (1) is superposed on the edge of the hole of the exhaust perforation (11), so that the constructor can be constructed on the top of the building (1), which is relatively safe.

And pre-stacked above the hole edge of the exhaust perforation (11) by the top of the building (1), so that the fan (3) installation work can be decoupled from the heat shield (2) and independently Helping the fan (3) and the vent hole (11) to form a gap-proof leakage edge (4) to prevent the fan (3) from drawing air to other sources (for example, the air inside the heat sink), causing "circulating negative pressure", so that the pumping process can simply pump the hot air inside the building.

It must be noted that most of the construction camps such as the installation of heat sinks are not the main business of large-scale buildings and construction enterprises, but belong to small and medium-sized enterprises or scattered work. Therefore, their improvement has always been paid less attention to the industry. Although it is considered to be relatively simple by the present invention, the progressive element is not simple, that is, the invention patent is not available, and the case is indeed improved to avoid the long-term drawbacks of "circulating negative pressure", so that the pumping process can be simply The heat in the building is pumped to enhance the heat dissipation efficiency. Based on the encouragement of research and development of small and medium-sized enterprises, it is still necessary to consider many aspects.

In summary, the present invention is indeed in line with industrial utilization, and is not found in publications or publicly used before application, nor is it known to the public, and has non-obvious knowledge, conforms to patentable requirements, and patents are filed according to law. . However, the above description is a preferred embodiment of the industry of the present invention, and all the equivalent changes made by the scope of the patent application of the present invention are within the scope of the claim.
