Description

Technical Field

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

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas delivery machinery in China. The fans usually include ventilators, blowers, and wind turbines.

[0003] When the fan is in use, the fan wheel rotates under the drive of the motor, and the air enters the wind chamber inside the fan and is finally discharged through the air outlet. However, after the air (referring to natural wind) enters the fan, the fan has a certain amount of heat inside, so that when the air is discharged, the temperature of the air will be slightly higher than the temperature of the air itself. When the user needs to discharge cold air at different temperatures (cold air refers to a temperature lower than that of natural wind), it is obviously impossible for the current fans to achieve this. Moreover, due to the wind wheel, the existing fans will generate certain noise when in use, which makes the use effect of the fan poor. For this reason, we propose a silent air cooler.

DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-8 As shown,

[0029] A silent air cooler, comprising a shell 1, a hood 2, a motor 3, a wind wheel 4, a lightweight and high-strength noise reduction mechanism 5 and a cooling mechanism 25; the shell 1 and the hood 2 are both single-layer structures; the open end of the shell 1 is fixedly connected to the hood 2, the interior of the hood 2 is provided with a motor 3, and the power output end of the motor 3 is connected to the wind wheel 4; the inner wall of the hood 2 is provided with a first slot body 6, a second slot body 7 and a third slot body 8, and the inner wall of the shell 1 is provided with a fourth slot body 9, a fifth slot body 10 and a sixth slot body 11; the interiors of the first slot body 6, the second slot body 7, the third slot body 8, the fourth slot body 9, the fifth slot body 10 and the sixth slot body 11 are all provided with a lightweight and high-strength noise reduction mechanism 5; the lightweight and high-strength noise reduction mechanism 5 comprises a noise reduction layer 12 and a lightweight and high-strength layer 13, and the noise reduction layer 12 and the lightweight and high-strength layer 13 are bonded and fixed ; The noise reduction layer 12 is one end close to the inner wall of the shell 1 or the hood 2; in the present embodiment, the shell 1 and the hood 2 are set to a single-layer structure, and the shell 1 and the hood 2 of the single-layer structure can be formed during the preparation process of the layer blow molding process, and the first slot body 6, the second slot body 7, the third slot body 8, the fourth slot body 9, the fifth slot body 10 and the sixth slot body 11 can be formed, and then the lightweight and high-strength noise reduction mechanism 5 is bonded to the inner wall of each slot body to achieve the noise reduction and silencing effect and high-strength performance; one end of the shell 1 is also provided with an air outlet 20, and the air outlet 20 is connected to a cold air mechanism 25, and the cold air mechanism 25 includes a tube body 26, and the interior of the tube body 26 is provided with an air duct 27, and the interior of the air duct 27 is provided with a cooling pipe 28; by providing the cold air mechanism 25, the temperature of the outlet air can be changed to meet the needs of different users;

[0030] In addition, the noise reduction layer 12 is a sound-absorbing cotton layer; since the thickness of the double-layer structure is generally twice or more than that of the single-layer structure, under the premise of equal thickness, the lightweight and high-strength noise reduction mechanism 5 will occupy the thickness of the "single-layer structure", and the noise reduction effect of the "single-layer structure" is better because the sound-absorbing cotton has a better sound-absorbing effect than plastic; moreover, the lightweight and high-strength layer 13 includes an epoxy resin layer and a fir fiber bundle. The strength of the lightweight and high-strength layer 13 formed by the epoxy resin layer and the fir fiber bundle is higher than that of plastic; at the same time, the weight of the noise reduction layer 12 and the lightweight and high-strength layer 13 combined is also lower than that of plastic of the same thickness, which is more convenient for users to use.

[0031] As a preferred embodiment; the cooling pipe 28 and the air duct 27 are both spiral-shaped, the cooling pipe 28 is arranged in the middle of the air duct 27, one end of the cooling pipe 28 is connected to a liquid inlet pipe 29, and the other end of the cooling pipe 28 is connected to a liquid outlet pipe 30, and the liquid inlet pipe 29 and the liquid outlet pipe 30 are both extended to the outside of the tube body 26; the purpose of this structural arrangement is to: arrange the cooling pipe 28 in the middle of the air duct 27, so that the air circulation is more uniform, and then the air is evenly heat-exchanged with the cooling pipe 28, thereby improving the cooling effect of the air; the use of the spiral cooling pipe 28 can increase the contact with the air The spiral air duct 27 is used to increase the area, so that the air can better contact the cooling pipe 28 without being too dispersed, thereby further improving the cooling effect of the air. In addition, it should be pointed out that: the present application mainly injects cold water into the cooling pipe 28, and different cold water temperatures can adjust different air outlet temperatures. For example, the lower the temperature of the cold water injected into the cooling pipe 28, the lower the temperature of the air after heat exchange, and the temperature adjustment of the air outlet can be achieved to meet the needs of different users. At the same time, cooling gas, such as nitrogen, etc., can also be injected into the cooling pipe 28. Both cooling liquid and cooling gas can be injected into the cooling pipe 28.

[0032] As a preferred embodiment; the air inlet end of the tube body 26 is provided with a first air guide plate 31, and the air outlet end of the tube body 26 is provided with a second air guide plate 32, the first air guide plate 31 and the second air guide plate 32 are respectively fixedly connected to the air duct 27, and the first air guide plate 31 and the second air guide plate 32 are both trumpet-shaped; by providing the first air guide plate 31, the air can enter the cooling pipe 28 more concentratedly, and the air can enter the cooling pipe 28 more quickly, thereby improving the cooling effect of the air; by providing the second air guide plate 32, the wind pressure can be further increased, thereby enhancing the air outlet effect.

[0033] As a preferred embodiment; the fir fiber bundle is arranged inside the epoxy resin layer; it can be understood that the preparation method of the lightweight and high-strength layer 13 is: first, the surface of the noise reduction layer 12 is covered with the fir fiber bundle using a mold, and then epoxy resin glue is injected. At this time, the epoxy resin glue will penetrate into various places of the fir fiber bundle, and when it solidifies, a lightweight and high-strength layer 13 can be formed. At this time, the fir fiber bundle is located inside the epoxy resin layer, and the sound-absorbing cotton of the noise reduction layer 12 is also bonded together to form a lightweight and high-strength noise reduction mechanism 5; the lightweight and high-strength noise reduction mechanism 5 can be bonded to the inner wall of each trough body by cutting and other means.

[0034] It is worth mentioning that the noise of the fan mainly comes from the wind wheel 4 and the power output shaft. Therefore, when the first slot body 6, the second slot body 7, the third slot body 8, the fourth slot body 9, the fifth slot body 10 and the sixth slot body 11 are set, the fourth slot body 9, the fifth slot body 10 and the sixth slot body 11 have basically surrounded the wind wheel 4, achieving a good noise reduction and silencing effect; the first slot body 6, the second slot body 7 and the third slot body 8 are arranged at the open end of the wind cover 2, on the one hand, to surround the power output shaft, and on the other hand, to form a gap at the connection between the shell 1 and the wind cover 2 to eliminate noise. Noise can also be reduced, and better noise reduction and silencing effects can be achieved; in addition, the motor 3 will also generate certain noise, but the noise is smaller than the noise mentioned above, and the main part of the wind hood 2 is thicker, and a mounting hole 24 is provided in the inner middle part of the wind hood 2, and the motor 3 is fixedly installed in the mounting hole 24; after the motor 3 is installed, the distance between the motor 3 and the outer wall of the wind hood 2 is sufficient to achieve better noise reduction and silencing effects; similarly, the noise reduction layer 12 and the lightweight high-strength layer 13 are integrated, and the position where the lightweight high-strength layer 13 is arranged is also sufficient to increase the strength of the fan as a whole.

[0035] As a preferred embodiment, a connecting groove 16 is provided between the shell 1 and the wind hood 2, and the shell 1 and the wind hood 2 are fixedly connected by a gasket 17 and a screw 18; the purpose of this design is to facilitate the installation and disassembly of the shell 1 and the wind hood 2.

[0036] As a preferred embodiment; an air inlet 19 is provided at one end of the shell 1, and an air outlet 20 is provided at the other end of the shell 1; a grille 21 is installed at the air inlet 19, and an air outlet pipe 22 is installed at the air outlet 20, and the air outlet pipe 22 is in a trumpet shape; by providing the grille 21, some larger particulate impurities can be filtered, thereby improving the air quality; in addition, the air outlet pipe 22 is in a trumpet shape, which can increase the air outlet range while concentrating the wind force, thereby achieving a better air outlet effect.

[0037] As a preferred embodiment; the wind wheel 4 is located inside the outer shell 1, and a wind cavity 23 is formed between the wind wheel 4 and the outer shell 1, one end of the wind cavity 23 is connected to the air inlet 19, and the other end of the wind cavity 23 is connected to the air outlet 20; it can be understood that the wind cavity 23 is located on the outside of the wind wheel 4, and is also arranged in a circular shape, which can increase the wind pressure, make the wind volume stronger, and thus improve the wind outlet effect.

[0038] The working process of the utility model is as follows: start the motor 3 to drive the fan wheel 4 to rotate, thereby forming a negative pressure inside the housing 1, and the air will enter the air cavity 23 from the air inlet 19, and then be discharged from the air outlet 20; when being discharged, the air will pass through the cold air mechanism 25, which can cool the air; if the user does not need cold air, the cold air mechanism 25 can be omitted (it can be used as a fixed part), and the air will be discharged normally.

[0039] It should be pointed out that the main problem in the prior art is that after the air (referring to natural wind) enters the fan, the fan has a certain amount of heat inside, so that when the air is discharged, the temperature of the air will be slightly higher than the temperature of the air itself. When the user needs to discharge cold air at different temperatures (cold air refers to a temperature lower than that of natural wind), it is obvious that this type of fan cannot achieve this.

[0040] Therefore, after the improvement of the present application, by providing a cold air mechanism 25, the air can be cooled when the air is discharged, so that the effect of discharging cold air can be achieved, and the temperature of the cold air can also be adjusted according to the temperature of the cooling pipe 28, so that the temperature of the air outlet can meet the needs of more different users and achieve different temperatures of air outlet;

[0041] In addition, by setting the outer shell 1 and the wind cover 2 as a single-layer structure, and providing various slots, and installing a lightweight and high-strength noise reduction mechanism 5 in each slot, the lightweight and high-strength noise reduction mechanism 5 includes a sound-absorbing cotton layer and a lightweight and high-strength layer 13. The sound-absorbing cotton layer can be used for noise reduction and sound absorption. The lightweight and high-strength layer 13 adopts an epoxy resin layer and a fir fiber bundle, and has the characteristics of lightness and high strength. Compared with the double-layer structure in the prior art, under the condition of the same thickness, the sound-absorbing cotton layer and the lightweight and high-strength layer 13 are lighter in weight, have better silencing effect, and have greater strength, so that the use effect of the fan is better; in addition, during production, a single-layer process structure is adopted to reduce the difficulty of its preparation process, thereby further reducing the production cost.

[0042] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
