Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifuge technology, specifically to a ventilation and heat dissipation structure for a room temperature centrifuge. Background Technology
[0002] When a room-temperature centrifuge is working, the motor drives the rotor to rotate counterclockwise, which generates a lot of heat through friction with the air in the chamber, causing the temperature inside the chamber to rise. Therefore, the chamber needs ventilation to dissipate heat. Traditional room-temperature centrifuges ventilate by drilling holes in the side wall or bottom of the chamber to allow hot air to escape.
[0003] The existing ventilation and heat dissipation structure of ambient temperature centrifuges has the following defects:
[0004] 1. The existing heat dissipation method of drilling holes at the bottom of the boiler cavity generates sharp noise during the heat dissipation process, resulting in a relatively high noise level during centrifuge operation;
[0005] 2. The existing centrifuges with holes drilled at the bottom of the chamber have poor heat dissipation. After the centrifuge has been running for a long time, the internal temperature cannot be effectively dissipated, resulting in poor heat dissipation performance and affecting the stability of operation.
[0006] Therefore, a solution is needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 This utility model provides a technical solution:
[0025] Example 1
[0026] Regarding the problem 1 that needs to be solved above: the existing heat dissipation method of drilling holes at the bottom of the boiler cavity generates sharp noise during the heat dissipation process, resulting in a relatively high noise level during centrifuge operation.
[0027] The solution is as follows: A ventilation and heat dissipation structure for a room-temperature centrifuge includes a centrifuge shell 9, a base plate 8 connected to the bottom of the centrifuge shell 9, a protective sleeve 4 between the top of the base plate 8 and the centrifuge shell 9, a chamber 3 located inside the protective sleeve 4, two layers of sound-insulating cotton 5 pasted in the gap between the chamber 3 and the protective sleeve 4, a motor 2 located between the middle of the centrifuge shell 9 and the base plate 8, a rotor 1 located on the drive end of the motor 2, a foam pad 6 installed between the bottom of the chamber 3 and the centrifuge shell 9, and several support columns 7 evenly distributed between the foam pad 6 and the base plate 8. The sound-insulating cotton 5 in different layers has a notch 12 on the right side and a notch 23 on the lower left side. The top space of the sound-insulating cotton 5 with notch 12 forms a heat dissipation duct 10, and the top space of the sound-insulating cotton 5 with notch 23 forms a heat dissipation duct 21. Specifically, as shown... Figure 2 and Figure 3 As shown in the figure, the arrows indicate the airflow direction within heat dissipation duct 10 and heat dissipation duct 21.
[0028] Furthermore, a support block is installed on the bottom of the centrifuge housing 9, and the top part of the base plate 8 is embedded in the centrifuge housing 9. The top height of the pot cavity 3 is lower than the top of the protective sleeve 4.
[0029] Furthermore, the bottom of the protective sleeve 4 is welded and fixed to the base plate 8, the outer edge of the sound insulation cotton 5 is attached to the protective sleeve 4 and the pot cavity 3 respectively, and the rotor 1 is located inside the pot cavity 3.
[0030] Furthermore, the outer edge of the foam pad 6 is flush with the outer edge of the pot cavity 3, the support column 7 is inserted into the inside of the foam pad 6, and the support column 7 is fixedly connected to the bottom plate 8 by bolts.
[0031] Furthermore, the position of gap one 12 is at the top of gap two 13, and there is a gap between the different layers of sound insulation cotton 5.
[0032] Furthermore, the motor 2 is fixed at the center position between the base plate 8 and the pot cavity 3.
[0033] Example 2
[0034] Regarding the second problem to be solved above: the heat dissipation effect of the existing centrifuge with holes drilled at the bottom of the chamber is poor. After the centrifuge has been running for a long time, the internal temperature cannot be effectively dissipated, resulting in poor heat dissipation performance and affecting the stability of operation.
[0035] The solution is as follows: By using longer heat dissipation ducts 10 and 11, the cooling distance of the hot air can be effectively extended. The protective cover allows for smoother airflow, and the longer ducts reduce wind speed, thus improving the ventilation and heat dissipation effect.
[0036] Working principle: During operation, when motor 2 drives rotor 1 to rotate counterclockwise at high speed, the friction between rotor 1 and the air inside the pot cavity 3 generates a large amount of heat, causing the temperature inside the pot cavity 3 to rise. The air inside the pot cavity 3 also rotates counterclockwise. The hot air passes through the gap between the pot cavity 3 and the protective sleeve 4 and enters the heat dissipation duct 10 (e.g., Figure 1 The location of the heat dissipation air duct 10 shown in the figure is in the first layer of the air duct, due to the gap 12 on the sound insulation cotton 5 (as shown in the figure). Figure 2 (as shown in the notch 12 position), so the hot air rotates counterclockwise through the notch 12 and enters the heat dissipation duct 2 11 (as shown in the image). Figure 1 The location of the heat dissipation duct 21 shown in the figure), in this duct, due to the gap 213 on the sound insulation cotton 5 (as shown in the figure), Figure 3 (as shown in the position of notch 2 13), so hot air can only go out through notch 2 13 and exit through the holes on the base plate. Due to the length of the heat dissipation duct 1 10 and the heat dissipation duct 2 11, the heat dissipation can be well dissipated and no significant noise will be generated.
[0037] The rotor-1, motor-2, pot cavity-3, protective sleeve-4, sound insulation cotton-5, foam pad-6, support column-7, base plate-8, centrifuge shell-9, heat dissipation duct one-10, heat dissipation duct two-11, notch one-12, and notch two-13 of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that the existing heat dissipation method of drilling holes at the bottom of the pot cavity generates sharp noise during the heat dissipation process, resulting in a large noise level during centrifuge operation. This utility model can effectively reduce the temperature of the centrifuge during operation by combining the above-mentioned components. The heat dissipation duct one and heat dissipation duct two can effectively increase the movement distance of hot air. The addition of the protective sleeve makes the air flow smoother. At the same time, the design of two layers of sound insulation cotton forms heat dissipation duct one and heat dissipation duct two, reducing wind speed and noise, and making the ventilation and heat dissipation effect better.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
