Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1-3, the invention discloses a heat exchange device of a smoke exhaust fan, which comprises a pipe body 10 and a container, wherein a cooling liquid is arranged in the container, the pipe body 10 is immersed in the cooling liquid, the pipe body 10 comprises a first port 11 and a second port 12, the first port 11 is connected with a smoke pipe, and the second port 12 is connected with the fan. The cooling fluid may be water.

Be provided with the stirring subassembly in body 10, the stirring subassembly includes mount pad 20 and the fan blade spare that is located the mounting bracket, and fan blade spare rotates with mount pad 20 to be connected. The fan blade spare includes installation department 22 and a plurality of blade 23, and a plurality of blade 23 encircle installation department 22 circumference and evenly set up, and blade 23 is the angle of inclination with the axis direction of installation department 22. The plurality of blades 23 are inclined at the same angle around the mounting portion 22. An attachment shaft 30 is provided below the attachment portion 22, and a plurality of stirrers 31 are provided on the attachment shaft 30. The airflow flows in the pipe 10 to drive the fan blade to rotate, and the fan blade rotates to drive the stirring member 31 to stir the airflow. Because the pipe 10 is immersed in the cooling liquid, heat exchange can be realized, and the temperature of the airflow in the pipe 10 is reduced, so that the damage to the fan caused by overhigh temperature of the airflow can be prevented. If the stirring assembly is not arranged, the outer wall of the pipe body 10 is in contact with cooling liquid, so that the problem that heat distribution of the center and the periphery of the air flow is uneven is easily caused, on one hand, the temperature of the air at the center of the pipeline is too high, and when the length of the pipeline is short, the air flow in the middle of the pipe body 10 is discharged from the fan without being cooled, and the fan can be damaged; on the other hand, the uneven temperature of the air flow in the pipe body 10 greatly affects the heat exchange efficiency, and the utilization rate of the heat energy is reduced.

The stirring member 31 has a rod-like or sheet-like shape. The plurality of stirring members 31 are arranged in order in the axial direction of the mounting shaft 30. The plurality of stirring members 31 are uniformly arranged around the circumferential direction of the mounting shaft 30 along the axial projection of the mounting shaft 30. When the air current flows, set up by the blade 23 slope of fan blade spare, the air current can drive fan blade spare rotatory, so, installation axle 30 also rotates in step, and the stirring piece 31 on the installation axle 30 can stir the air current for the heat of air current is even in the body 10. In the stirring process of the stirring member 31, the airflow stirring can be realized only by the flow of the airflow without adding a driving source such as a motor in the pipe fitting.

The pipe body 10 may be a U-shaped pipe. The tube 10 may also have a serpentine shape.

A plurality of stirring components are arranged in the pipe body 10. The purpose of setting up a plurality of stirring subassemblies is in order to stir by the multistage to can be more even with the uneven air current stirring of heat.
