Description

Technical Field

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

[0002] A fan is a mechanical device used to generate airflow or increase gas pressure. A common fan includes a housing with an air inlet and an air outlet, an impeller rotatably arranged in the housing for generating airflow and compressing gas through the rotation of blades, and a motor for driving the impeller to rotate. In order to protect the fan, the fan is usually installed in a cabinet.

[0003] When working, the high-speed rotation of the motor will generate a lot of heat, so the motor needs to be cooled. The usual practice is to set air inlets and outlets on the opposite or adjacent walls of the cabinet to speed up the flow of air in 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 in the cabinet and is not easy to discharge, which causes the temperature in the host room to be high, and the cold air coming in from the air inlet of the cabinet will heat the hot air in 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 "CN221010596U" discloses an integrated cabinet, which reduces the internal temperature of the cabinet by setting a wind-dispersing box with multiple heat sinks inside the cabinet. However, this technical solution has the disadvantages of complex structure and high manufacturing cost.

[0004] Therefore, a fan integrated cabinet with good heat dissipation effect and simple structure needs to be designed. Utility Model Content

[0005] The utility model aims to provide a fan integrated cabinet to solve the above technical problems in view of the defects and shortcomings of the prior art, and has the advantages of good heat dissipation effect and simple structure.

[0006] To achieve the above object, the utility model provides a fan integrated cabinet, comprising:

[0007] The cabinet body is formed by enclosing a plurality of facing walls, and the facing walls are provided with air outlets;

[0008] A fan is installed inside the cabinet, with its air outlet end penetrating through a side wall of the cabinet and communicating with the outside, and its air inlet end penetrating through a side wall of the cabinet and communicating with the outside;

[0009] An air supply member, comprising an air suction port and an air supply end, wherein the air supply end is located on one side of the motor housing of the fan;

[0010] A first air intake fan is mounted on a face wall of the cabinet and is arranged on a different face wall from the air outlet;

[0011] Wherein, the distance between the air inlet of the air supply member and the air outlet of the first air intake fan is less than or equal to 100 mm.

[0012] Optionally, the distance between the air intake port of the air supply member and the air outlet of the first air intake fan is less than or equal to 80 mm.

[0013] Optionally, the motor housing has a heat dissipation air duct running through in the axial direction, the air supply member is a cold air hood, the cold air hood is arranged at the rear end of the motor housing, and the air supply end of the cold air hood is connected to the air inlet end of the heat dissipation air duct.

[0014] Optionally, a second air intake fan is installed in the cold air hood or at the rear end of the motor housing.

[0015] Optionally, the second suction fan and the motor shaft are coaxially arranged.

[0016] Optionally, the fan is a centrifugal fan, the air inlet end of the centrifugal fan is an air inlet cylinder, and the air outlet end of the centrifugal fan is an air guide cylinder; the centrifugal fan also includes a volute, an impeller rotatably arranged in the volute and used to generate airflow and compress gas through the rotational movement of blades, and a motor that drives the impeller to rotate.

[0017] Optionally, the air inlet tube and the air guide tube of the centrifugal fan are both connected to the cabinet wall via a sealing plate.

[0018] Optionally, the air outlet is an exhaust louver arranged on two adjacent side walls of the face wall where the first intake fan is located.

[0019] Optionally, an exhaust fan is provided on the air outlet of the cabinet to exhaust the hot air in the cabinet.

[0020] Optionally, the motor housing has a heat dissipation air duct running through in the axial direction, and the air supply member is an air duct; the air supply end of the air duct is arranged at the rear end of the motor housing and is connected to the air inlet end of the heat dissipation air duct.

[0021] Compared with the prior art, the advantages of this application are:

[0022] Since the air supply end of the air supply member is located on one side of the motor housing of the fan, and the distance between the air intake of the air supply member and the air outlet of the first air intake fan is less than or equal to 100 mm. Therefore, the hot air circulating in the cabinet can no longer enter the air intake of the air supply member and then flow to the surface of the motor. This ensures that the cold air entering the air inlet is not heated by the hot air of the cabinet, but is continuously blown to the motor to cool the motor, and the hot air is discharged through the air outlet, so that the fan integrated cabinet has the advantage of good heat dissipation effect. In addition, since the first air intake fan can accelerate the cold air outside the cabinet to enter the air supply member, the heat dissipation effect of the fan motor can be improved. In addition, compared with the prior art, this structure does not need to add a wind venting box with a heat dissipation plate, or a similar structure, so it has the advantage of simple structure.

[0044] Embodiment 1

[0045] Please refer to Figures 1 to 7, an embodiment of the utility model provides a fan integrated cabinet 100, comprising: a cabinet 1, a fan, an air supply member and a first air intake fan 4. The cabinet 1 is formed by a plurality of facing walls 11. In the present embodiment, the cabinet 1 is square as a whole, but in other embodiments, the cabinet 1 as a whole may also be in other shapes, such as a columnar shape, etc., without specific limitation. An air outlet a is provided on the facing wall 11 of the cabinet 1. Optionally, the air outlet a may be provided on one of the facing walls 11, or the air outlet a may be provided on a plurality of facing walls 11 at the same time to accelerate the dissipation of heat in the cabinet 1. The fan is assembled inside the cabinet 1, and specifically, the fan may be fixed in the cabinet 1 by fasteners (not shown in the figure). Specifically, the fan is assembled in the support base 12 in the cabinet 1 by fasteners. Optionally, the fan includes a casing having an air inlet end and an air outlet end, an impeller (not shown) rotatably arranged in the casing for generating airflow and compressing gas through the rotational movement of blades; and a motor 24 for driving the impeller to rotate. In this embodiment, the air outlet end of the fan is arranged through a side wall 11 of the cabinet 1 and is connected to the outside, and the air inlet end of the fan is arranged through a side wall 11 of the cabinet 1 and is connected to the outside. Optionally, in this embodiment, the fan is specifically a centrifugal fan 2. The air outlet end of the centrifugal fan 2 is an air guide 23, which is arranged through a side wall 11 of the cabinet 1 and is connected to the outside; the air inlet end of the centrifugal fan 2 is an air inlet 22, which is arranged through a side wall 11 of the cabinet 1 and is connected to the outside. Specifically, the casing of the centrifugal fan 2 is a volute 21, and the impeller is rotatably arranged in the volute 21. Of course, in other embodiments, the fan may also be other fans, whose air inlet and air outlet are connected to the outside through a ventilation pipe (not shown in the figure) through a side wall 11 of the cabinet 1, which is not limited here. The air supply member has an air inlet e and an air supply end f, and the air supply end f is located on one side of the motor housing 241 of the fan. Specifically, in the present embodiment, the air supply end f may be attached to the outer surface of the motor housing 241, or the air supply end f may be arranged close to the outer surface of the motor housing 241. As long as the cold air at its air outlet can blow directly to the outer surface of the motor housing 241 to dissipate heat for the motor 24. The first air intake fan 4 is mounted on the face wall 11 of the cabinet 1, and is arranged on a different face wall 11 from the air outlet a. Specifically, the first air intake fan 4 may be an exhaust fan. That is, cold air is drawn from outside the cabinet 1 into the cabinet 1 to dissipate heat for the motor 24 of the fan in the cabinet 1. The distance h between the air inlet e of the air supply member and the air outlet g of the first air suction fan 4 is less than or equal to 100 mm. Optionally, the distance h between the air inlet e of the air supply member and the air outlet g of the first air suction fan 4 can be 0 mm (that is, the outer shells of the air supply member and the air outlet g of the first air suction fan 4 fit together), 10 mm, 40 mm, 60 mm, 80 mm, 100 mm; as long as the distance h between the air inlet e of the air supply member and the air outlet g of the first air suction fan 4 is less than or equal to 100 mm.

[0046] Since the air supply end f of the air supply member is located on one side of the motor housing 241 of the fan, and the distance h between the air inlet e of the air supply member and the air outlet g of the first air intake fan 4 is less than or equal to 100 mm, the hot air circulating in the cabinet 1 can no longer enter the air inlet e of the air supply member and then flow to the surface of the motor 24. This ensures that the cold air entering the air inlet is not heated by the hot air of the cabinet 1, but is continuously blown to the motor 24 to cool the motor 24, and the hot air is discharged through the air outlet a, so that the fan integrated cabinet 100 has the advantage of good heat dissipation effect. In addition, compared with the prior art, this structure does not need to add a wind-dissipating box with a heat dissipation plate, or a similar structure, so it has the advantage of simple structure.

[0047] In order to further ensure that hot air cannot enter the air supply member through the air suction port e of the air supply member, preferably, the distance h between the air suction port e of the air supply member and the air outlet g of the first suction fan 4 is less than or equal to 80 mm, which has a better effect.

[0048] Optionally, see Figures 4 to 7 In this embodiment, the motor housing 241 has a heat dissipation duct b that penetrates along the axial direction. Specifically, there are multiple heat dissipation ducts b, which are arranged around the motor housing 241. The heat dissipation duct b is set from the tail end to the front end of the motor housing 241. It should be noted that in this field, the tail end of the motor housing 241 refers to the end of the motor 24 away from the fan volute 21, and the end close to the fan volute 21 is the front end. The air supply member is a cold air cover 3; the cold air cover 3 is covered at the tail end of the motor housing 241, and the air supply end f of the cold air cover 3 is connected to the air inlet end c of the heat dissipation duct b. In this way, the cold air delivered from the first air intake fan 4 enters through the air intake port e of the cold air cover 3, and blows from the air supply end f to the air inlet end c of the heat dissipation duct b of the motor housing 241, and the cold air flows through the housing heat dissipation duct b and flows out from the air outlet end d of the heat dissipation duct b of the motor housing 241, so as to take away the heat on the surface of the motor housing 241. The hot air flowing out of the air outlet d of the heat dissipation air duct b passes through the internal cavity of the cabinet 1 and then flows out of the cabinet 1 through the air outlet a of the cabinet 1. In this way, the heat inside the cabinet 1 can be reduced to dissipate the heat of the motor 24.

[0049] To increase the air intake of the cold air hood 3, optionally, refer to Figure 6In this embodiment, the tail end of the motor housing 241 is equipped with a second air intake fan 5. Since the second air intake fan 5 can generate negative pressure, the efficiency of the cold air hood 3 sucking cold air can be increased, thereby improving the heat dissipation effect of the motor housing 241. Optionally, the second air intake fan 5 and the motor shaft 242 are coaxially configured. Of course, in other embodiments, the air intake fan can also be independently assembled at the tail end of the motor housing 241. It can be understood that the second air intake fan 5 can also be assembled in the air duct in the cold air hood 3, so that the effect of increasing the efficiency of the cold air hood 3 sucking cold air can be achieved. Optionally, a filter 8 is also provided at the air intake port e end of the cold air hood 3. In this way, when the debris passes through the air intake port e, it will be blocked by the filter 8 to avoid entering the cold air hood 3 and damaging the hood, or the second air intake fan 5 at the tail end of the motor housing 241.

[0050] 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.

[0051] Optionally, see Figure 1 , Figure 2 and Figure 4 In this embodiment, the air outlet a is an exhaust louver disposed on the two adjacent side walls 11 of the face wall 11 where the first air intake fan 4 is located. In this way, the cold air entering through the first air intake fan 4 passes through the cold air cover 3 and the heat dissipation air duct b of the motor housing 241, and flows out from the air outlet d of the heat dissipation air duct b, and 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 and the air outlet a of the cabinet 1 are set. When the fan is a centrifugal fan 2, since the centrifugal fan 2 has a vortex shell 21 in the electrode axial direction, and the vortex shell 21 will block the hot air flowing out of the air outlet d of the heat dissipation air duct b of the motor housing 241, therefore, the air outlet a is set on the two adjacent side walls 11 of the face wall 11 of the air inlet, and its air flow path is shorter, so the heat in the cabinet 1 can be quickly discharged.

[0052] Embodiment 2

[0053] This embodiment is basically the same as the first embodiment, and the difference is only in the specific structure of the air outlet a of the cabinet 1. In order to speed up the hot air in the cabinet 1 to be discharged outside the cabinet 1, optionally, please refer to Figure 8 In this embodiment, an exhaust fan 7 is provided on the air outlet a of the cabinet 1 to accelerate the exhaust of hot air in the cabinet 1 to the outside of the cabinet 1.

[0054] Embodiment 3

[0055] This embodiment is basically the same as the first embodiment, and the difference is only in the specific structure of the air supply member. Specifically, in this embodiment, the motor housing 241 has a heat dissipation duct b that penetrates along the axial direction, and the heat dissipation duct b is set from the tail end to the front end of the motor housing 241. The air supply member is an air duct (not shown in the figure); the air supply end f of the air duct is arranged at the tail end of the motor housing 241 and is connected to the air inlet end c of the heat dissipation duct b. In this way, the cold air entering from the first air intake fan 4 enters through the air intake port e of the air duct, and blows from the air supply end f to the air inlet end c of the heat dissipation duct b of the motor housing 241, and the cold air flows through the heat dissipation duct b of the housing, and flows out from the air outlet end d of the heat dissipation duct b of the motor housing 241, so as to take away the heat on the surface of the motor housing 241. The hot air flowing out of the air outlet end d of the heat dissipation duct b passes through the internal cavity of the cabinet 1 and then flows out of the cabinet 1 through the air outlet a of the cabinet 1. In this way, the internal heat of the cabinet 1 can be reduced to dissipate the heat of the motor 24.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
