[0049] like Figure 3 As shown, the mine chamber fan unit 100 of the utility model is equipped with a hydraulic fan 20 and a surface cooler assembly 30 on the base 11a. In this embodiment, the hydraulic fan 20 and the surface cooler assembly 30 are arranged in sequence in the direction from the front side of the paper to the depth side of the paper. The surface cooler assembly 30 has a coil 33 inside the shell 34, and the coil 33 is used to supply cooling water S to flow inside it, so as to exchange heat between the cooling water S and the air passing through the surface of the coil 33.

[0050] In this embodiment, a cooling water inflow pipe 31 for cooling water S to flow into the coil 33 of the cooling water assembly 30 is connected to the upper side of one end (left end in the figure) of the shell 34 of the cooling water assembly 30, and a cooling water outflow pipe 32 for cooling water S to flow out of the coil 33 of the cooling water assembly 30 is connected to the lower side of one end of the shell 34 of the cooling water assembly 30 (see FIG.

[0052] Figure 4 The utility model is a schematic diagram showing the cooling water flow path of the mine chamber fan unit.

[0053] like Figure 4 As shown, a connecting pipe 232 is connected between the cooling water outflow pipe 32 of the condenser and the cooling water inflow pipe 22 of the fan, and is used to connect the cooling water outflow pipe 32 of the condenser and the cooling water inflow pipe 22 of the fan.

[0054] According to such a mine chamber fan unit, by arranging the cooling water inlet and outlet pipes as described above, the structure is simple and the repair and maintenance of the connection between the surface cooler assembly and the hydraulic fan is convenient.

[0055] In this embodiment, when the mine chamber fan unit 100 is in operation, the cooling water S from the cooling water supply device (not shown) is connected to the cooling water inflow pipe 31 of the cooling water assembly 30. That is, the cooling water enters the coil 33 of the cooling water assembly 30 from the cooling water inflow pipe 31 of the cooling water assembly 30, flows out from the cooling water outflow pipe 32 of the cooling water assembly 30, flows into the hydraulic fan 20 through the fan cooling water inflow pipe 22 via the connecting pipe 232, and flows out from the fan cooling water outflow pipe 21.

[0056] According to such a mine chamber fan unit, it can be easily installed and moved at any time.

[0057] Figure 5 It is a structural diagram schematically showing the hydraulic fan of the utility model.

[0058] like Figure 5 As shown, the hydraulic fan 20 includes a hydraulic motor 23 and a fan 24. In this embodiment, the fan 24 and the hydraulic motor 23 are arranged in sequence in the direction from the front side of the paper to the depth side of the paper. The fan cooling water inlet pipe 22 is connected to the lower side of one end of the hydraulic motor 23, and the fan cooling water outlet pipe 21 is connected to the upper side of one end of the hydraulic motor 23. The fan 24 includes a blade 241, an air duct member 242 and a fan cover 243 (see Figure 2 ). The air duct member 242 is a member arranged around the blade 241 to efficiently supply air, and is used to form an air supply channel, which is preferred in this embodiment. By using the air duct member, the air supply efficiency is improved. In addition, the fan cover 243 is a member designed to protect the blade 241. It is designed to improve safety, but it is not necessary, and the fan cover may not be provided. By using the fan cover to safely protect the blades, safety is improved.

[0059] In this embodiment, if Figure 1 and Figure 2As shown, the fan cover 243 is fixed to one side of the external box body 10. According to such a mine chamber fan unit, the fan cover 243 is fixed to one side of the external box body 10, which is convenient for use and easy to disassemble and assemble.

[0060] In addition, in this embodiment, if Figure 2 As shown, the shape of the external box body is a rectangular parallelepiped, and the fan 24, the hydraulic motor 23 and the surface cooler assembly 30 are arranged in sequence along the width direction of the top surface of the external box body 10.

[0061] According to such a mine chamber fan unit, the supply path of cooling water can be shortened and the refrigeration efficiency can be improved.

[0062] The working principle of the mine chamber fan unit 100 of the present invention is described in detail below.

[0063] As described above, when the mine chamber fan unit 100 is in operation, first, the cooling water S from the cooling water supply device (not shown) flows into the coil 33 of the surface cooler assembly 30 through the surface cooler cooling water inflow pipe 31, and flows out from the surface cooler cooling water outflow pipe 32, and flows into the hydraulic motor 23 of the hydraulic fan 20 through the connecting pipe 232 and the fan cooling water inflow pipe 22. At this time, the cooling water S drives the hydraulic motor 23 to work (drives the water wheel of the hydraulic motor 23 to drive the connecting shaft to rotate), and the hydraulic motor 23 drives the blades 241 of the fan 24 to rotate, thereby guiding the high-temperature air in the chamber (at Figure 3 , Figure 5 The airflow (the airflow closer to the front side than the fan 24) is discharged from the end of the blade 241 to the rear side (the depth side of the paper), thereby achieving strong convection heat exchange between the high-temperature air and the cooling water S in the coil 33 of the surface cooler assembly 30 that does not flow through the hydraulic motor 23. Therefore, low-temperature air can be delivered to reduce the temperature inside the chamber space.

[0064] As described above, the utility model can realize regional air supply by only connecting water pipes, so the size of the whole machine is small, the machine can be moved at any time, and the installation is convenient. In addition, the air supply is realized by using water power, and no electric drive is required, which has high safety and reliability. In addition, the cooling water from the cooling water supply device can be used as a driving force for power output and as a refrigerant for heat exchange.

[0065] Moreover, by using the cooling water S flowing out of the cooler assembly 30 as the driving force for driving the hydraulic motor 23 (hydraulic fan 20), compared with the cooling water S as the driving force first flowing into the hydraulic motor 23 (hydraulic fan 20) and then flowing into the cooler assembly 30, it is possible to avoid the cooling water S being heated by relatively high-temperature hot air and then flowing into the cooler assembly 30 to perform the heat exchange function as a refrigerant, thereby improving the cooling efficiency of the cooling water, achieving better cooling, and improving the heat exchange effect.

[0066] Of course, the mining chamber fan unit of the utility model is not limited to the structure described in the above embodiment. As long as it can exert a good cooling function and ensure convenient installation and safety and reliability, various appropriate changes can be made.

[0067] It should be noted that the various aspects of the utility model described for one embodiment can be included in other different embodiments, although not specifically described for the other different embodiments. In other words, all embodiments and / or the features of any embodiment can be combined in any way and / or combination, as long as they are not contradictory.
