Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an integrated fan cabinet. Background Art

[0002] A fan is a mechanical device used to generate air flow or increase gas pressure. Common fans include a casing having an air inlet end and an air outlet end, an impeller rotatably disposed inside the casing for generating air flow and compressing gas through the rotational movement of blades; and a motor for driving the impeller to rotate. To protect the fan, the fan is usually assembled in a cabinet.

[0003] During operation, the high-speed rotation of the motor will generate a large amount of heat, so it is necessary to cool the motor. The usual method is to provide an air inlet and an air outlet on the opposite or adjacent side walls of the cabinet to accelerate the air flow inside the cabinet for heat dissipation. However, in this technical solution, the heat generated by the motor usually diffuses inside the cabinet, and some hot air circulates inside the cabinet and is not easily discharged, resulting in a relatively high temperature inside the main engine room. Moreover, the cold air entering from the air inlet of the cabinet will heat the hot air inside the cabinet before reaching the outer wall of the motor, so its cooling effect is not obvious. For this reason, the Chinese utility model patent with the authorization announcement number of "CN221010596U" discloses an integrated cabinet, which reduces the temperature inside the cabinet by providing a plurality of heat dissipation plates with a wind-dispersing box body inside the cabinet. However, this technical solution has the disadvantages of complex structure and high manufacturing cost.

[0004] Therefore, there is a need to design an integrated fan cabinet with good heat dissipation effect and simple structure. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an integrated fan cabinet aiming at the defects and deficiencies of the prior art, to solve the above technical problems, and it has the advantages of good heat dissipation effect and simple structure.

[0006] To achieve the above purpose, the utility model provides an integrated fan cabinet, including:

[0007] A cabinet body formed by enclosing a plurality of side walls, and the side walls are provided with an air inlet and an air outlet, and the air inlet and the air outlet are arranged on different side walls;

[0013] Optionally, an air suction fan is assembled inside the cold air hood or at the tail end of the motor housing.

[0014] Optionally, the air suction fan and the motor shaft are coaxially arranged.

[0015] Optionally, a filter mesh cover is further arranged between the air suction port of the cold air hood and the air inlet of the cabinet body; the filter mesh cover includes a housing with ventilation holes, and filter meshes are arranged on the ventilation holes; one end of the housing abuts against the wall surface of the cabinet body, and the other end of the housing abuts against the cold air hood; the air inlet of the cabinet body is communicated with the air suction port of the cold air hood through the filter mesh cover.

[0016] Optionally, an exhaust fan is arranged at the air outlet of the cabinet body to discharge the hot air in the cabinet body.

[0019] Optionally, the fan is a centrifugal fan, and both the air outlet end and the air inlet end of the centrifugal fan are connected to the wall surface of the cabinet body through a sealing plate.

[0020] Compared with the prior art, the advantages of the present application are as follows:

[0042] Embodiment 1

[0043] Please refer to Figures 1 to 7, an embodiment of the present utility model provides a fan integrated cabinet 100, including: a cabinet body 1, a fan, and a air supply member. Among them, the cabinet body 1 is formed by enclosing a plurality of side walls 11. Among them, in this embodiment, the cabinet body 1 is generally square, but in other embodiments, the cabinet body 1 can also be in other shapes, such as cylindrical, etc., which is not specifically limited. The side wall 11 of the cabinet body 1 has an air inlet a and an air outlet b, and the air inlet a and the air outlet b are arranged on different side walls 11. Optionally, the air inlet a and the air outlet b can be arranged on the opposite side walls 11 of the fan motor 24; or the air inlet a is arranged on one of the side walls 11, and the air outlet b can be arranged on other side walls 11; or two side walls 11 are provided with the air inlet a, and two side walls 11 are provided with the air outlet b; as long as the air inlet a and the air outlet b are arranged on different side walls 11 to form air convection for heat dissipation. The fan is assembled inside the cabinet body 1. Specifically, the fan can be assembled in the cabinet body 1 through fasteners (not shown in the figure). Specifically, the fan is assembled in the support base 12 inside the cabinet body 1 through fasteners. Optionally, the fan includes a casing having an air inlet end and an air outlet end, an impeller (not shown in the figure) rotatably arranged inside the casing for generating air flow and compressing gas through the rotational movement of the blades; and a motor 24 for driving the impeller to rotate. In this embodiment, the air outlet end of the fan penetrates through one side wall 11 of the cabinet body 1 and communicates with the outside, and the air inlet end of the fan penetrates through one side wall 11 of the cabinet body 1 and communicates with the outside. Optionally, in this embodiment, the fan is specifically a centrifugal fan 2. The casing of the centrifugal fan 2 is a volute 21. The air outlet end of the centrifugal fan 2 is a guide cylinder 23, and the guide cylinder 23 penetrates through one side wall 11 of the cabinet body 1 and communicates with the outside; the air inlet end of the centrifugal fan 2 is an air inlet cylinder 22, and the air inlet cylinder 22 penetrates through one side wall 11 of the cabinet body 1 and communicates with the outside. Of course, in other embodiments, the fan can also be other fans, and its air inlet end and air outlet end penetrate through one side wall 11 of the cabinet body 1 and communicate with the outside through a ventilation pipe (not shown in the figure), which is not limited here. The air supply member has an air suction port 31 and an air supply end 32, and the air supply end 32 is located on one side of the motor housing 241 of the fan. Specifically, in this embodiment, the air supply end 32 can be attached to the outer surface of the motor housing 241, or the air supply end 32 can be arranged close to the outer surface of the motor housing 241. As long as the cold air at its air outlet end can directly blow on the outer surface of the motor housing 241 to dissipate heat from the motor 24. The distance h between the air suction port 31 of the air supply member and the air inlet a of the cabinet body 1 is less than or equal to 100 mm. Optionally, the distance h between the air suction port 31 of the air supply member and the air inlet a of the cabinet body 1 can be 0 mm (i.e., the air supply member is attached to the side wall 11 of the air inlet a), 10 mm, 40 mm, 60 mm, 80 mm, 100 mm; as long as the distance h between the air suction port 31 of the air supply member and the air inlet a of the cabinet body 1 is less than or equal to 100 mm. Of course, in another embodiment, the air supply member penetrates through the air inlet a of the cabinet body 1, and its air suction port 31 is located outside the cabinet body 1.

[0044] Since the air supply end 32 of the air supply member is located on one side of the motor housing 241 of the blower, and the distance h between the air suction port 31 of the air supply member and the air inlet a of the cabinet 1 is less than or equal to 100 mm, or the air supply member penetrates through the air inlet a of the cabinet 1 and its air suction port 31 is located outside the cabinet 1, the hot air circulating inside the cabinet 1 cannot enter the air suction port 31 of the air supply member and then flow to the surface of the motor 24. In this way, it can ensure that the cold air entering from the air inlet a is not heated by the hot air of the cabinet 1, and then continuously cools the motor 24. The hot air is discharged through the air outlet b. Therefore, it has the advantage of good heat dissipation effect. In addition, compared with the prior art, this structure does not need to add a heat dissipation plate and air duct box or similar structure, so it has the advantage of simple structure.

[0045] To further ensure that the hot air cannot enter the air supply member through the air suction port 31 of the air supply member, preferably, the distance h between the air suction port 31 of the air supply member and the air inlet a of the cabinet 1 is less than or equal to 80 mm, and the effect is better.

[0046] Optionally, please refer to Figures 4 to 7 , in this embodiment, the motor housing 241 has a heat dissipation air duct c that penetrates axially. Specifically, there are multiple heat dissipation air ducts c, which are arranged around the axis of the motor housing 241. The heat dissipation air duct c penetrates from the tail end to the front end of the motor housing 241. It should be noted that in the art, the tail end of the motor housing 241 refers to the end of the motor 24 away from the volute 21 of the blower, and the end close to the volute 21 of the blower is the front end. The air supply member is a cold air hood 3; the cold air hood 3 covers the tail end of the motor housing 241, and the air supply end 32 of the cold air hood 3 is communicated with the air inlet end d of the heat dissipation air duct c. In this way, the cold air entering from the air inlet a of the cabinet 1 enters through the air suction port 31 of the cold air hood 3, blows from the air supply end 32 to the air inlet end d of the heat dissipation air duct c of the motor housing 241, the cold air flows through the housing heat dissipation air duct c, and flows out from the air outlet end e of the housing heat dissipation air duct c, so as to take away the heat on the surface of the motor housing 241. The hot air flowing out from the air outlet end e of the heat dissipation air duct c passes through the internal cavity of the cabinet 1 and then flows out of the cabinet 1 through the air outlet b of the cabinet 1. In this way, the internal heat of the cabinet 1 can be reduced to dissipate heat from the motor 24.

[0047] To increase the air intake of the cold air hood 3, optionally, please refer to Figure 6 , in this embodiment, a suction fan 4 is assembled at the tail end of the motor housing 241. Since the suction fan 4 can generate negative pressure, the efficiency of sucking cold air into the cold air hood 3 can be increased, and thus the heat dissipation effect on the motor housing 241 can be improved. Optionally, the suction fan 4 and the motor shaft 242 are coaxially arranged. Of course, in some other embodiments, the suction fan 4 can also be independently assembled at the tail end of the motor housing 241. It can be understood that the suction fan 4 can also be assembled in the air duct inside the cold air hood 3, and in this way, the effect of increasing the efficiency of sucking cold air into the cold air hood 3 can also be achieved.

[0048] In order to prevent debris from entering the cold air cover 3 through the air inlet 31 and damaging the cold air cover 3 or the air inlet fan 4 at the rear end of the motor housing 241, optionally, please refer to Figure 5 In this embodiment, a filter screen cover 5 is further arranged between the air inlet 31 of the cold air cover 3 of the fan integrated cabinet 100 and the air inlet a of the cabinet 1; the filter screen cover 5 includes a cover shell 51 with a vent f, and a filter screen 52 is arranged on the vent f; one end of the cover shell 51 abuts against the wall 11 of the cabinet 1, and the other end of the cover shell 51 abuts against the cold air cover 3; the air inlet a of the cabinet 1 is connected to the air inlet 31 of the cold air cover 3 through the filter screen cover 5. In this way, when the debris passes through the air inlet 31, it will be blocked by the filter screen cover 5 to avoid entering the cold air cover 3 and damaging the air inlet fan 4 in the hood or the tail end of the motor housing 241.

[0049] Optionally, see Figure 1 and Figure 2 In this embodiment, the fan is a centrifugal fan 2, and both the air outlet and the air inlet of the centrifugal fan 2 are connected to the cabinet 1 wall 11 through the sealing plate 6. Specifically, since the air outlet of the centrifugal fan 2 is the air guide 23, and the air inlet is the air inlet 22; and the free ends of the air guide 23 and the air inlet 22 are flared structures, when the air guide 23 and the air inlet 22 are inserted into the cabinet 1 wall 11, there is a large gap between the air inlet 22, the air inlet 22 and the cabinet 1 wall 11. Connecting both the air outlet and the air inlet of the centrifugal fan 2 to the cabinet 1 wall 11 through the sealing plate 6 can prevent debris from entering the cabinet 1 through the gap to damage the equipment in the cabinet 1.

[0050] Optionally, see Figure 1 , Figure 2 , Figure 4 In this embodiment, the air inlet a is a plurality of air inlet holes arranged in an array on the face wall 11 of the cabinet 1 near the rear end of the motor 24. The air outlet b is an exhaust louver arranged on the two adjacent side walls 11 of the face wall 11 where the air inlet a is located. In this way, the cold air entering through the air inlet a passes through the cold air cover 3 and the heat dissipation air duct c of the motor housing 241, and after flowing out from the air outlet end e of the heat dissipation air duct c, it can be discharged through the exhaust louvers on the face walls 11 on both sides of the motor 24, thus forming an air flow path. The positions of the air inlet a and the air outlet b of the cabinet 1 are set. When the fan is a centrifugal fan 2, since the centrifugal fan 2 has a volute 21 in the electrode axial direction, and the volute 21 will block the hot air flowing out from the outlet end e of the heat dissipation duct c of the motor housing 241, the air outlet b is set on the two adjacent side walls 11 of the face wall 11 of the air inlet a, and the air flow path is shorter, so the discharge of hot air in the cabinet 1 can be accelerated.

[0051] Embodiment 2

[0052] This embodiment is basically the same as the first embodiment, except that an exhaust fan 7 is added to the air outlet b of the cabinet body 1 to increase the rate of discharging the hot air inside the cabinet body 1. Optionally, please refer to Figure 8 , in this embodiment, an exhaust fan 7 is provided at the air outlet b of the cabinet body 1 to discharge the hot air in the cabinet body 1 to the outside of the cabinet body 1.

[0053] Embodiment Three

[0054] This embodiment is basically the same as the first embodiment, except for the specific structure of the air supply member. Specifically, the motor housing 241 has a heat dissipation air duct c that penetrates axially, and the air supply member is an air duct (not shown in the figure); the air supply end 32 of the air duct is provided at the tail end of the motor housing 241 and communicates with the air inlet end d of the heat dissipation air duct c.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application.
