Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1 to fig. 2.
A liquid cooled constant load fan housing assembly as shown in fig. 1, comprising: centrifugal fan casing 1, ring flange 2, separate heat exchanger 7 and liquid cooling coil 9, ring flange 2 sets up at centrifugal fan casing 1's back, can fix through the screw, and sound construction. In this embodiment, a motor mounting seat 11 is disposed on an outer side surface of the flange 2, a motor 12 is disposed on the motor mounting seat 11, and a rotating shaft of the motor 12 extends into the centrifugal fan casing 1.
The front surface of the centrifugal fan shell 1 is provided with an air inlet guide ring 10 which is concentric with the flange plate 2, so that the centrifugal fan shell is conveniently connected with an air inlet pipeline to guide air flow. An air outlet 5 is formed in the bottom of the centrifugal fan shell 1, and air flow pressure is improved and then is discharged out through the air outlet 5.
The heat insulation cover 7 is arranged on the front surface of the flange plate 2 and is positioned in the centrifugal fan shell 1, and the heat insulation cover is welded and fixed, so that the air tightness is good. In this embodiment, the heat shield 7 is of a circular ring structure, a sealing sleeve 8 connected with a central hole of the flange plate 2 is arranged in the heat shield 7, and the sealing sleeve 8 and the central hole of the flange plate 2 are welded and fixed, so that the structure is stable. The sealing sleeve 8 is beneficial to the penetration of the motor rotating shaft, so that the motor rotating shaft extends into the centrifugal fan shell 1 to drive the impeller to rotate.
With liquid cooling coil 9 setting in separate heat exchanger 7 and be located the outside of seal cover 8, in this embodiment, liquid cooling coil 9 is in the heat exchanger 7 spiral distribution that separates, extension cooling route, enlarges cooling range and effect. In addition, it has heat insulating part 6 to fill in heat shield 7, heat insulating part 6 adopts thermal-insulated cotton or foaming thermal-insulated plastics, reduces heat to the transmission of ring flange 2 in centrifugal fan casing 1 through heat insulating part 6, in addition liquid cooling coil 9's effect, greatly reduced the temperature rise condition of ring flange 2, be favorable to when promoting thermal-insulated effect, reduce heat insulating part 6 and heat shield 7's thickness to reduce the occupation to 1 inner space of centrifugal fan casing, be favorable to the design and the work of impeller.
As shown in fig. 2, in this embodiment, the flange 2 is provided with a liquid inlet port 3 and a liquid outlet port 4 connected to two ends of the liquid cooling coil pipe 9, and is connected to the liquid inlet port 3 and the liquid outlet port 4 through an external cooling water circulation system to form a cooling circulation, so as to take away heat of the heat insulating member 6 in the heat insulating cover 7, thereby improving the heat insulating effect.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
