Description

A communication transmission cabinet chassis air guide and heat dissipation device

Technical Field

The utility model relates to the technical field of cabinet chassis heat dissipation, in particular to an air guiding and heat dissipating device for a communication transmission cabinet chassis.

Background Art

The communication transmission cabinet is used for power distribution or communication data transmission. The inside of the cabinet generates heat due to power or communication data transmission, so various heat dissipation systems are needed to solve the heat dissipation problem. The current practice is to cool down by delivering cold air through air conditioning, and the equipment in the cabinet is usually integrated into one subsystem. The heat dissipation systems of multiple cabinets are connected together. When delivering cold air for cooling, the hot air flow discharged from the bottom of the cabinet mixes with the cold air from the air conditioner, so that the temperature of the cold air in the cold air channel increases, affecting the heat dissipation of other cabinet groups. In order to ensure the temperature of the cold air in the cold air channel, the current common practice is to lower the temperature of the air conditioner and increase the speed of the air conditioner to ensure that other cabinets can work normally, but this practice will increase the power consumption of the air conditioner and increase the cost of use. To this end, the present application proposes a communication transmission cabinet chassis air guide and heat dissipation device to solve the above problems.

DETAILED DESCRIPTION

The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model. All directional indications in the utility model (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

As shown in Figures 1-3, this embodiment provides a communication transmission cabinet chassis air guiding and heat dissipation device, which includes a guide air duct 1, which is vertically installed on one side of each set of communication transmission cabinet chassis, and the upper end of the guide air duct 1 is an air outlet end 101, and the lower end of the guide air duct 1 is connected to the static pressure box 2, and an air inlet 201 is provided on one side of the static pressure box 2. The air inlet 201 is a bell mouth, and the port edge of the air inlet 201 extends outward and is provided with a plurality of mounting holes at the extended position. Bolts pass through the mounting holes and are fixedly connected to the outer wall of the chassis' air outlet, thereby connecting the guide air duct 1 with the chassis' air outlet, and a fan assembly is provided on the static pressure box 2. A temperature controller 3 is installed on one side of the static pressure box 2. In order to prevent the temperature controller 3 from falling into dust, a box body 4 is fixed on one side of the static pressure box 2, and the temperature controller 3 is installed in the box body 4.

As shown in Figures 1 and 3, in the structural design of the guide air duct 1, in this embodiment, the guide air duct 1 is a rectangular structure, and a plurality of mounting frames 102 are arranged on the side of the guide air duct 1 close to the chassis. The mounting frames 102 are fixedly connected to the outer wall of the chassis by bolts, thereby ensuring the stability of the guide air duct 1. An air outlet 103 is arranged at the air outlet end 101 of the guide air duct 1, and the air outlet 103 is a mesh structure, which can prevent dust from being sucked into the interior when hot air is not exhausted, thereby affecting the service life of components inside the chassis, and can also prevent other debris from falling into the guide air duct 1 and blocking the circulation of the guide air duct 1.

The air outlet end 101 of the guide air duct 1 is arranged above the chassis, so as to guide the hot air to the top of the chassis and separate it from the cold air below.

A fan cover 5 is provided between the guide air duct 1 and the static pressure box 2 to prevent the fan assembly from blowing in large particles that would obstruct ventilation.

The fan assembly includes a fixing frame 6 and a fan 7. There are two fans 7, and two accommodating chambers are provided on the fixing frame 6. The two fans 7 are respectively installed in the accommodating chambers. The blowing direction of the fan 7 is perpendicular to the inlet direction of the air inlet 201, and the blowing direction of the fan 7 is directly opposite to the outlet end 101. When blowing, the wind blown by the fan 7 directly enters the guide air duct 1, so that the air pressure in the guide air duct 1 is reduced, so that the hot air in the chassis quickly enters the guide air duct 1, and the wind blown by the fan 7 will not enter the chassis, effectively preventing external dust from entering the chassis. In order to achieve the exhaust speed of hot air, the fan 7 uses a stepless speed fan, and the fan 7 is connected to the temperature controller 3. When the temperature controller 3 detects that the temperature at the bottom of the chassis is too high, the temperature controller 3 turns on the fan 7 and controls the rotation speed of the fan 7 to export the hot air at the bottom of the chassis through the guide air duct 1.

Its working principle is: the internal temperature of the chassis is monitored by the temperature controller 3, and the rotation speed of the fan 7 in the fan assembly can be adjusted according to the temperature inside the chassis, and the hot air in the chassis is discharged through the air guide channel, and the cold air in the cold air channel is blown into the chassis, which can not only quickly cool down the inside of the chassis, but also avoid the mixing of hot air and cold air inside the chassis, thereby reducing the temperature of the cold air in the cold air channel, reducing the power consumption of the air conditioner, and achieving the purpose of energy saving and emission reduction.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
