Description

Technical Field

[0001] The present invention relates to the technical field of air suspension blowers, and more particularly to an air suspension blower with a heat dissipation structure. Background Art

[0002] Air suspension fan is also called air suspension centrifugal blower. Air suspension centrifugal blower (single-stage high-speed centrifugal blower) is a new concept blower. It adopts three core high-end technologies: "ultra-high-speed direct-connected motor", "air suspension bearing" and "high-precision single-stage centrifugal impeller". It has created a new era of high-efficiency, high-performance, low-noise and low-energy consumption fans. It is a new generation of high-tech civilian products developed with the experience of aviation turbomachinery design.

[0003] The principle of air suspension fan is mainly based on the principle of gas dynamics, using the high-speed airflow and gas dynamic pressure generated by the high-speed rotating impeller to achieve contactless support and rotation of the rotor. This fan realizes the suspension and rotation of the rotor through air suspension bearing technology, high-speed permanent magnet motor and its control technology. It has the advantages of no friction, no vibration, and quietness, and is suitable for high-speed, high-precision, and high-load application scenarios.

[0004] At present, the existing air suspension fans have poor self-heating performance, and because the air suspension fans will generate high temperatures when running, long-term high temperatures may cause damage to the air suspension fans.

[0005] Therefore, in view of this, the existing structure is studied and improved, and an air suspension fan with a heat dissipation structure is provided, in order to achieve a more practical purpose. Summary of the invention

[0006] 1. Technical problems to be solved

[0020] Compared with the prior art, the advantages of the present invention are:

The filtering component can effectively absorb dust in the inhaled gas, and the cooling component can significantly reduce the temperature of the gas entering the air suspension fan. When the gas is operating in the air suspension fan, the temperature rises, but because the gas temperature has been reduced in advance, until the gas in the air suspension fan is discharged, it still does not reach a high temperature that may damage the air suspension fan, and the cooling gas that subsequently enters can cool down the internal high temperature of the air suspension fan. In this way, the heat dissipation of the air suspension fan can be achieved, avoiding the high temperature that reaches a dangerous level when the air suspension fan is operating, and thereby preventing the air suspension fan from being damaged under high temperature operation.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figure 1 - Figure 5 An air suspension fan with a heat dissipation structure includes a grid base 1 and an air suspension fan body 2 fixed to one side of the top of the grid base 1. The grid base 1 and the air suspension fan body 2 are the main bodies of the entire device for air suspension operations.

[0041] An air inlet 201 is provided at one end of the air suspension fan body 2, and an exhaust port 202 is provided at the other end of the air suspension fan body 2. A cooling component 3 is provided at the port of the air inlet 201 for significantly cooling the gas that is about to enter the air suspension fan body 2. In this way, the gas will not reach a high temperature that may cause harm after working inside the air suspension fan body 2. At the same time, the gas that enters subsequently will cool the heat inside the air suspension fan body 2.

[0042] The cooling assembly 3 includes a ventilation sleeve 301, both ends of which are fixedly installed with flange interfaces 3011, one end of the ventilation sleeve 301 is fixed to the air inlet 201 through the flange interface 3011, a cold liquid storage tank 302 is arranged in the vertical direction of the ventilation sleeve 301, the middle part of the cold liquid storage tank 302 runs through the interior of the entire ventilation sleeve 301, one end of the cold liquid storage tank 302 is fixedly provided with a liquid injection port 303, and the other end of the cold liquid storage tank 302 is fixed A drain port 304 is provided, and a control valve 305 is fixedly installed on the injection port 303 and the drain port 304. When the external air is introduced through the ventilation sleeve 301, it will pass through the gap between the cold liquid storage tank 302 of the cooling component 3 and the ventilation sleeve 301, thereby realizing the cooling of the gas. During the continuous cooling operation, new cold liquid can be added through the injection port 303, and the cold liquid with increased temperature is discharged from the drain port 304 to ensure the effect of the cold liquid inside the cold liquid storage tank 302.

[0043] See also Figure 2 , Figure 3and Figure 4 Specifically, the cold liquid storage tank 302 includes an upper T-shaped liquid sealing box 3021 and a lower T-shaped liquid sealing box 3022. The upper T-shaped liquid sealing box 3021 and the lower T-shaped liquid sealing box 3022 have the same structure and are symmetrically arranged. The cold liquid is stored between the upper T-shaped liquid sealing box 3021 and the lower T-shaped liquid sealing box 3022, and the cold liquid is ensured to be interconnected between the upper T-shaped liquid sealing box 3021 and the lower T-shaped liquid sealing box 3022 through a slender liquid storage tube 3023.

[0044] A plurality of slender liquid storage tubes 3023 are arranged between the upper T-shaped liquid sealing box 3021 and the lower T-shaped liquid sealing box 3022 .

[0045] Specifically, the liquid injection port 303 is fixed on the side of the upper T-shaped liquid sealing box 3021, and the pipeline of the liquid injection port 303 is connected to the inside of the upper T-shaped liquid sealing box 3021. Injecting cold liquid from the liquid injection port 303 can ensure that the cold liquid in the entire cold liquid storage tank 302 is filled.

[0046] Specifically, the drain port 304 is fixed on the side of the lower T-shaped sealing liquid box 3022, and the pipeline of the drain port 304 is connected to the lowest liquid level inside the lower T-shaped sealing liquid box 3022. Discharging the cold liquid from the drain port 304 can ensure complete discharge of the cold liquid.

[0047] Specifically, a first temperature sensing probe 3024 is fixedly disposed inside the upper T-shaped sealing liquid box 3021, and a second temperature sensing probe 3025 is fixedly disposed inside the lower T-shaped sealing liquid box 3022. The first temperature sensing probe 3024 and the second temperature sensing probe 3025 sense the temperature at corresponding positions respectively, and when the temperature of the cold liquid rises and the cooling effect does not meet the standard, a reminder to replace the cold liquid can be provided.

[0048] Specifically, there are fourteen slender liquid storage tubes 3023, and the slender liquid storage tubes 3023 run through the entire side of the ventilation sleeve 301. A sealing gasket 3026 is provided at the connection between the slender liquid storage tubes 3023 and the ventilation sleeve 301. The contact area between the gas and the slender liquid storage tubes 3023 is increased, and the slender liquid storage tubes 3023 are thin-walled copper tubes, which facilitate heat exchange. At the same time, the sealing gasket 3026 can prevent the gas from being discharged outward from the connection between the slender liquid storage tubes 3023 and the ventilation sleeve 301.

[0049] Specifically, an air passage 3027 is provided between the two elongated liquid storage tubes 3023, and the width of the air passage 3027 is smaller than the thickness of the inner cavity of the elongated liquid storage tube 3023. This further ensures that the air contacts the elongated liquid storage tube 3023 over a large area, thereby improving the cooling effect.

[0050] Embodiment 2:

[0051] Based on the above embodiment 1, further description is given.

[0052] See also Figure 1 , Figure 2 and Figure 5 A filter component 4 is provided at one end of the cooling component 3 for filtering dust and other substances that may be contained in the external gas.

[0053] The filter assembly 4 includes an air cylinder 401, one end of which is fixed to the other end of the ventilation sleeve 301 through a flange interface 3011, and an adsorbent cotton 402 is arranged inside the air cylinder 401. The gas enters from one end of the air cylinder 401, absorbs dust through the adsorbent cotton 402, and then is discharged from the other end to the ventilation sleeve 301 of the cooling assembly 3.

[0054] Specifically, the gas cylinder 401 includes a bearing cylinder 4011 and a metal cover cylinder 4012, and the adsorbent cotton 402 is placed between the bearing cylinder 4011 and the metal cover cylinder 4012. When the bearing cylinder 4011 and the metal cover cylinder 4012 are separated, the adsorbent cotton 402 can be replaced conveniently.

[0055] Specifically, a plurality of positioning holes 4013 are formed on the metal cover tube 4012, and a corresponding number of magnetic plugs 4014 are fixedly provided on the carrier tube 4011, and the magnetic plugs 4014 are correspondingly inserted into the positioning holes 4013. By utilizing the magnetic attraction between the metal cover tube 4012 and the magnetic plugs 4014, after the magnetic plugs 4014 are inserted into the positioning holes 4013, the carrier tube 4011 and the metal cover tube 4012 can be quickly connected.

[0056] Working principle:

[0057] When the entire device is in use, first, external air enters through one end of the air cylinder 401, and then, under the adsorption effect of the adsorption cotton 402, flows into the ventilation sleeve 301 from the other end of the air cylinder 401, and passes through the air passage 3027. At this time, there is a large temperature difference between the cold liquid in the slender liquid storage tube 3023 and the gas in the air passage 3027, and heat exchange can be completed quickly. In this way, the gas passing through the air passage 3027 can be effectively cooled, and the cooled gas can effectively cool the inside of the air suspension fan body 2.

[0058] At the same time, the filter assembly 4, the cooling assembly 3 and the air suspension fan body 2 in the device are connected by a Ferra disc structure, so that the disassembly, cleaning and replacement of the filter assembly 4 and the cooling assembly 3 can be facilitated.

[0059] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
