Description

Cabinet and air supply system

technical field

The utility model relates to the technical field of communication, in particular to a cabinet and an air supply system.

Background technique

With the increasing integration of communication units, the number of communication units installed in the computer room is increasing, and the total heat generated by the communication units is also increasing. In order to cool the communication unit and prolong its service life, the traditional working method of "cooling the environment first and then cooling the equipment" is generally adopted in the prior art, that is, by controlling the ambient temperature of the entire computer room, the ambient temperature is reduced to An appropriate temperature value thus indirectly lowers the temperature of the communication unit. The disadvantage of this method is that since all objects in the computer room, such as walls and floors, consume a large part of cold air, this solution wastes a lot of cooling resources while cooling the communication unit.

In the existing technology, the method of "cooling the equipment first, then cooling the environment" is proposed. The main idea is to use the closed cold aisle to precisely supply air "on demand" according to the heat generation requirements of different equipment. In this way, the reasonable distribution of refrigeration support can be realized, the utilization efficiency of air conditioners can be greatly improved, and electric energy can be saved. This is the precise air supply technology currently used.

Specifically, the precise air supply technology refers to the technology that directly transmits the cold air from the air conditioner to the communication cabinet through a special air duct. When the cold air is sent into the communication cabinet, an interface device—an air blower is required. The existing The types of air blowers are mainly divided into two types: door panel type and suspension type. From the appearance, the door panel air blower is an integral box cover with air inlet holes on it. This air blower is used to replace the front door of the communication cabinet with the communication unit installed. When the air is blowing, the cold air passes through the air duct It enters the cabinet through the air inlet, thereby cooling the communication unit; the structure of the suspended air blower is similar to that of the door panel air blower, and it is also an integral box cover with an air inlet, but the suspended air blower When the air blower is in use, there is no need to replace the entire front door of the communication cabinet. It only needs to be hung on the front door of the cabinet, and through the opening on the front door of the cabinet, the cold air will be delivered to the cabinet through the air inlet hole through the opening.

The defect of the above two air blowers provided in the prior art is that they are an integral box cover, which is relatively heavy in structure, and when in use, the plane cabinet front door of the cabinet will become a certain depth. The front door of the box-type cabinet will affect the normal opening of the front door of the cabinet; in addition, since the cold air needs to enter the cabinet through the air blower, there is a problem that the air blower itself will consume more cooling capacity.
