Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.
Referring to fig. 1, a self-cooling type fan room 10 according to a preferred embodiment of the present invention includes an air inducing fan room 100 and a blower fan room 200. The induced draft fan house 100 and the blower house 200 are connected together, and both have a common wall 300. Wherein the common wall 300 extends in a first direction D1.
The induced draft fan room 100 is usually provided with an induced draft fan 110, an induced draft fan air outlet 112 of the induced draft fan 110 is communicated with other equipment, and air enters the induced draft fan 110 from an induced draft fan air inlet 111 of the induced draft fan 110 and then enters other equipment through the induced draft fan air outlet 112 so as to provide required air volume for the work of other equipment. In the illustrated embodiment, the centerline of the induced draft fan 110 is parallel to the first direction D1. That is, the center line of the induced draft fan 110 is parallel to the extending direction of the common wall 300. It can be understood that the arrangement of the induced draft fan 110 may also be changed according to actual needs, so that the center line of the induced draft fan 110 is perpendicular to the first direction D1.
In addition to the induced draft fan 110, other devices for maintaining the normal operation of the induced draft fan room 100 are generally required to be arranged in the induced draft fan room 100. The induced draft fan 110 and the devices need to ventilate and dissipate heat during operation. In order to improve the quality of the acoustic environment in the plant area where the induced draft fan room 100 is located, noise abatement needs to be performed on the induced draft fan 110 and the ventilation system thereof, so as to effectively reduce the noise value in the plant area.
The blower room 200 is usually provided with a blower 210 for providing required air volume for other equipment to work. In the illustrated embodiment, the centerline of the blower 210 is parallel to the first direction D1. That is, the center line of the blower fan 210 is parallel to the extending direction of the common wall 300.
In addition to the blower 210, other devices for maintaining the normal operation of the blower room 200 are generally required in the blower room 200. The blower 210 and these devices are operated to ventilate and dissipate heat. In order to improve the quality of the acoustic environment in the factory site where the blower room 200 is located, the blower 210 and its ventilation system also need to be subjected to noise abatement, so as to effectively reduce the noise value in the factory site.
In order to ventilate and dissipate heat of the fan room 10 including the air inducing fan room 100 and the air blower room 200, such as in the illustrated embodiment, an air inlet passage 150 is provided on the first wall 120 of the air inducing fan room 100 to provide an inlet of cooling air for the air inducing fan room 100. A ventilation passage 310 is provided in the common wall 300 to provide a communication port through which cooling air flows for the induced air room 100 and the blower room 200.
Depending on the arrangement of the devices in the blower room 200 and the blower inlet 211 of the blower 210, the ventilation channel 310 is preferably disposed on the common wall 300 at a position far from the blower inlet 211 in the first direction D1. Therefore, after entering the blower room 200 from the induced-draft fan room 100 through the ventilation channel 310, the cooling air firstly flows through other equipment in the blower room 200, then enters the blower 210 from the blower air inlet 211, is pressurized by the blower 210, and then enters other air-using equipment from the blower air outlet 212, so that the flow path of the cooling air in the blower room 200 can be effectively increased, the cooling air can fully flow through the equipment in the blower room 200, the purpose of cooling the blower 210 and other equipment in the blower room 200 by utilizing the inlet air of the blower 210 is realized, the number of heat-radiating equipment such as fans in the blower 210 can be reduced, and the cost is effectively reduced.

And more preferably, the intake passage 150 is distant from the ventilation passage 310 in the first direction D1. Thus, after entering the induced draft fan room 100 through the air inlet passage 150, the cooling air can flow through the induced draft fan 110 and other devices in the induced draft fan room 100, so that the flow path of the cooling air in the induced draft fan room 100 can be effectively increased, and the induced draft fan room 100 can be sufficiently cooled.
