Description

TECHNICAL FIELD

[0001] The present application relates to the field of experimental instruments, in particular to a centrifuge device for centrifugal separation of samples in experiments in the fields of food, biopharmaceuticals, environmental protection, etc. BACKGROUND

[0002] Centrifuges are experimental instruments widely used in the fields of food, biopharmaceuticals, environmental protection, etc., which separate different materials to be separated in the experimental process by using centrifugal force, and can realize multiple functions such as separation, concentration, purification, etc. of samples.

[0003] The centrifuge includes a centrifugal component and a centrifugal motor. When the centrifugal motor is running, the motor shaft of the centrifugal motor drives the centrifugal component to rotate at high speed. Generally, the centrifugal component at least includes a centrifuge rotor rotating by motor driving, and a sample container for containing samples. When the centrifuge rotor is driven by the motor to rotate at high speed, the sample placed in the sample container is correspondingly rotated. Through the centrifugal force, the separation of the sample is realized.

[0004] In the fields such as biopharmaceuticals, there are certain requirements for the temperature of the sample. In order to ensure the activity of the sample, it is necessary to keep the sample at a lower temperature. During the operation of the centrifuge, the temperature of the sample may rise, thereby negatively affecting the sample. Therefore, there is a centrifuge with temperature control function, which includes a refrigeration device including a condenser, a compressor, a refrigerant pipeline, etc. The refrigerant pipeline transports the refrigerant to the compressor. The refrigerant is compressed into a liquid state in the compressor, and the refrigerant pipeline transports the refrigerant compressed into a liquid state to the centrifugal component. At the centrifugal component, the refrigerant absorbs heat and expands, for example, expands into a gaseous state, thereby cooling the centrifugal component and further cooling the sample at the centrifugal component.

[0005] The prior art shows that the centrifuge with temperature control function is proved to be advantageous in many aspects, but it still has some deficiencies or defects. These deficiencies or defects, for example, relate to insufficient environmental compatibility or insufficient safety of the centrifuge, etc., thereby there is a need for further improvement of the structure of the centrifuge. CONTENT OF THE INVENTION

[0006] The present application is made to overcome the technical problems existing in the prior art centrifuge. The purpose of the present application is to improve the structure of the existing centrifuge device, so as to improve at least one of the safety and environmental compatibility of the centrifuge.

[0007] In known cases, the refrigerants widely used in centrifuge refrigeration devices include R134a, R22, etc., but these refrigerants are fluorine-containing refrigerants, which have some shortcomings in environmental compatibility. On the other hand, if a fluorine-free refrigerant is selected, the known choices include: R1270, R600a, R290, R32, R717, all of which are flammable and have some safety deficiencies. Therefore, fluorine-free refrigerants such as R290 have many restrictions in the use of centrifuges, such as being commonly used in low-temperature refrigeration equipment with less liquid charge, or as a component of low-temperature mixed refrigerants, and the corresponding refrigeration device has a relatively high installation sealing performance.

[0008] Based on the understanding of the above two different refrigerant selections and characteristics, the inventors of the present application propose a scheme to improve the structure of the existing centrifuge equipment. The centrifuge structure of the present application can allow more efficient use of other environmentally friendly refrigerants other than fluorine-containing refrigerants. For example, through the centrifuge of the present application, R290 or other environmentally friendly but flammable refrigerants can be safely used, reducing the safety risk when these refrigerants leak, thereby effectively improving the use restrictions of these refrigerants in centrifuges and expanding the application scenarios.

[0009] The present application provides a centrifuge device, which comprises a housing, a centrifuge device, a refrigeration device and electronic devices are contained in the housing, wherein the centrifuge device comprises a centrifuge component capable of performing a centrifugal separation operation on a sample, and the refrigeration device comprises a refrigerant pipeline assembly connected to the centrifuge device to provide a refrigerant to the centrifuge device to cool the sample in the centrifuge device. In this centrifuge device, a partition is provided in the housing, which separates the space in the housing into a refrigeration area and a non-refrigeration area, and the refrigeration area and the non-refrigeration area are independent of each other and do not have fluid communication. Among them, at least the refrigeration device is located in the refrigeration area, and the electronic devices are located in the non-refrigeration area. And a first air inlet and a first air outlet communicating with the refrigeration area are provided on the housing, and external air can enter the refrigeration area through the first air inlet, and the heat-exchanged air in the refrigeration area can be discharged from the refrigeration area through the first air outlet.

[0010] As mentioned above, if an environmentally friendly fluorine-free refrigerant (including but not limited to: R1270, R600a, R290, R32, R717) is used, the inventors of the present application believe that if the refrigerant in the refrigeration device leaks, the flammable refrigerant that leaks will contact components that are prone to generate sparks, such as the electronic devices in the centrifuge, which will have the risk of explosion.

[0011] The electronic devices are, for example, circuit boards, switches, relays and the like used for power supply and / or control in the centrifuge device. In particular, the switches, relays and the like can generate electric sparks at the moment of opening and closing.

[0012] Based on such understanding, the present inventors propose that, by separating the space in the housing of the centrifuge device into a refrigeration region and a non-refrigeration region, the components such as the circuit boards, switches and the like that are prone to generate sparks are placed in the non-refrigeration region and are isolated from the refrigerant. This can improve the safety of the centrifuge device and, in particular, can eliminate or at least significantly reduce the risk of explosion caused by contact between the refrigerant and the components prone to generate electric sparks.

[0013] In addition to improving safety and being environmentally friendly, the use of the partition also has the advantages of low cost, ease of maintenance and high reliability. For example, if the safety is improved by increasing the sealing of the refrigeration device in the centrifuge, the installation cost of the centrifuge will increase, and as the centrifuge operates, the sealing of the refrigerant can fail, thus requiring additional maintenance and repair after installation to ensure the integrity of the sealing components in the refrigeration device, but sometimes it cannot completely guarantee that the refrigerant leakage is completely eliminated, and the reliability is not strong.

[0014] In particular, the refrigeration device comprises a condenser located near the first air inlet and positioned such that the ambient air flowing into the refrigeration region via the first air inlet flows through the condenser; a condenser fan installed on the condenser; a compressor; and a refrigerant pipe assembly comprising a first refrigerant pipe connected between the condenser and the compressor and a second refrigerant pipe leading into the centrifuge device. The condenser, the condenser fan, the compressor and the refrigerant pipe are all located in the refrigeration region. Such an arrangement can ensure that the refrigeration device containing the refrigerant is isolated as a whole in the refrigeration region, preventing it from leaking into the non-refrigeration region and improving the safety of the centrifuge device.

[0015] Preferably, a second air inlet and a second air outlet are also provided on the housing and communicate with the non-refrigeration region, so that the ambient air can enter the non-refrigeration region via the second air inlet, and the heat-exchanged air in the non-refrigeration region can be discharged from the non-refrigeration region via the second air outlet. Thus, the components in the non-refrigeration region can also be cooled by heat dissipation.

[0016] Preferably, an electronic device fan is provided in the non-refrigeration region. The electronic device fan can facilitate the circulation of air in the non-refrigeration region. Thus, by providing the electronic device fan, it helps to improve the heat dissipation effect of the circuit boards, switches and other electronic devices

[0017] Further, the centrifuge device further comprises a centrifugal motor for driving the centrifugal component to rotate, and the centrifugal motor is located in the refrigeration region. Different from the aforementioned electronic devices located in the non-refrigeration region, the centrifugal motor is located in the refrigeration region. The main consideration includes: generally, the electronic devices such as conventional motor, for example, brushless motor, etc. are not easy to generate sparks, and the region containing the centrifugal motor can be communicated with the region containing the refrigeration device, and the air used for heat dissipation of the refrigeration device can also be used for heat dissipation of the centrifugal motor, and the utilization efficiency of the air for heat dissipation can be improved.

[0018] In an exemplary structure, the centrifuge device comprises an upper portion and a lower portion, the refrigeration region comprises a first refrigeration sub-region located in the upper portion and a second refrigeration sub-region located in the lower portion, wherein the refrigeration device is located in the first refrigeration sub-region, and the centrifugal motor is located in the second refrigeration sub-region; the upper portion comprises a first base plate, the lower portion comprises a second base plate, the first base plate supports the centrifugal device and the refrigeration device, and separates the upper portion and the lower portion, and the second base plate supports the centrifugal motor. Wherein, a third air inlet is formed in the first base plate, and the first refrigeration sub-region and the second refrigeration sub-region are communicated with each other through the third air inlet. A third air outlet is provided in the second refrigeration sub-region, and the air after heat exchange with the centrifugal motor can be discharged through the third air outlet.

[0019] Through such a structure, the air flowing into the first refrigeration sub-region from the first air inlet can also be used to cool the centrifugal motor. Thus, it is not necessary to provide an additional fan for the centrifugal motor, which is conducive to reducing the manufacturing cost of the centrifuge device.

[0020] Preferably, the partition comprises a first partition extending from the housing to the outer peripheral surface of the centrifugal device, and the refrigeration device and the electronic device are located on two sides of the centrifugal device respectively. In such an arrangement, the centrifugal device also plays a role of separating the refrigeration region and the non-refrigeration region, which can simplify the installation of the first partition, and the subsequent after-sales maintenance work is also relatively convenient.

[0021] The partition can further comprise a second partition arranged around the centrifugal motor to form the second refrigeration sub-region, and extending from the first base plate to the second base plate. Such an arrangement of the second partition can make the cooling air flow around the centrifugal motor for one round, and fully contact the centrifugal motor, thereby improving the cooling efficiency.

[0022] The material for manufacturing the partition can be selected as required. For example, the partition can be made of a material selected from the following: a metal plate, a foam material, or a combination of a metal plate and a foam material. Among them, the foam material can be selected from, for example, PUR material, EVA material, or other flame-retardant foam materials. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0030] The specific embodiments of the present application will be described below in detail with reference to the drawings. It should be understood that the drawings shown in the drawings are only the preferred embodiments of the present application, and do not constitute a limitation on the scope of the present application. Those skilled in the art can make various obvious modifications, variations, equivalent replacements to the present application on the basis of the embodiments shown in the drawings, and under the premise of not contradicting, the technical features described in the following different embodiments can be combined with each other arbitrarily, which all fall within the protection scope of the present application.

[0031] Figure 1 A schematic perspective view showing a centrifuge apparatus 1 of the present application is shown, wherein the centrifuge apparatus 1 is partially exploded to show the specific internal components and configurations of the centrifuge apparatus 1.

[0032] ​​The centrifuge apparatus 1 includes a housing 10 in which components of the centrifuge apparatus 1 are housed. Specifically, the components housed in the housing 10 of the centrifuge apparatus 1 include a centrifuge device 20, a refrigeration device 30, a centrifuge motor 40, and electronics 60.

[0033] The centrifuge device 20 is exemplarily shown in the figures as a cylindrical shape, but the centrifuge device 20 can also take other common shapes and configurations of existing centrifuge devices, which are also within the scope of the present application. The centrifuge device 20 has a centrifuge cavity formed therein in which a centrifuge component (not specifically shown) can be disposed, and by rotating the centrifuge component, centrifugation of a sample contained in the centrifuge cavity can be performed. Here, the centrifuge device 20 and the centrifuge component therein are conventional components in the art, and their specific configurations will not be described in further detail herein.

[0034] The refrigeration device 30 includes a condenser 31, a compressor 32, and a refrigerant piping assembly. Refrigerant of the refrigeration device 30 is transported between the components of the refrigeration device 30 via the refrigerant piping assembly, and refrigerant can be transported to the centrifuge device 20 via the refrigerant piping assembly. The refrigerant used in the refrigeration device 30 can be R290, or other refrigerant types commonly used in the art. As previously mentioned, R290 is a refrigerant form of propane, which is a hydrocarbon refrigerant, and has the characteristics of being free of fluorine and chlorine, and does not cause damage to the ozone layer, and has very small greenhouse effect. Other non-fluorine containing refrigerants listed in the summary of the invention are also known refrigerant choices in the art, and will not be recited herein.

[0035] Specifically, as can be seen from Figure 1 and Figure 2 , the refrigerant piping assembly includes a first refrigerant piping 33 and a second refrigerant piping 34. The first refrigerant piping 33 is connected between the condenser 31 and the compressor 32, which allows refrigerant to be transported from the compressor 32 to the condenser 31 to allow the condenser 31 to cool air flowing therethrough. The second refrigerant piping 34 is connected between the compressor 32 and the centrifuge device 20, for transporting refrigerant from the compressor 32 to the centrifuge device 20 for cooling the centrifuge device 20.

[0036] In the exemplary configuration shown in the figures, the centrifuge apparatus 1 includes a double-layer structure, in which the centrifuge device 20 and the refrigeration device 30 are housed in the upper layer portion, while the centrifuge motor 40 is located in the lower layer portion, and directly below the centrifuge device 20, which is connected to the centrifuge component in the centrifuge device 20 to drive the centrifuge component to rotate. Of course, the double-layer structure shown is a preferred structure of the present application, and the centrifuge apparatus 1 can also be a single-layer structure, and embodiments of the single-layer structure are also within the scope of the present application.

[0037] The housing 10 also houses electronic components 60, which may include, for example, a circuit board and a power switch. Preferably, the electronic components 60 and the cooling device 30 are positioned on opposite sides of the centrifuge device 20. In the case of the double-layer structure shown in the figure, the electronic components 60 may be located in the upper layer, with the cooling device 30 disposed on one side of the centrifuge device 20 and the electronic components 60 disposed on the other side. In another alternative structure, the space in the housing 10 that houses the electronic components 60 may extend through the upper and lower layers, and be arranged side by side with the space in the upper layer that houses the cooling device 30 and the space in the lower layer that houses the centrifuge motor 40.

[0038] In this application, the space within the housing 10 of the centrifuge device 1 is divided into two regions: a refrigeration region 2 and a non-refrigeration region 3. A separator is used to separate the refrigeration region 2 and the non-refrigeration region 3, ensuring that there is no, or at least substantially no, fluid communication between them. This prevents gas from flowing from the refrigeration region 2 into the non-refrigeration region 3, and vice versa. Furthermore, each of the refrigeration region 2 and the non-refrigeration region 3 has its own dedicated air inlet and air outlet, as will be described in more detail below.

[0039] Here, the term "basically" means that even if there is some gas leakage between the refrigerated zone 2 and the non-refrigerated zone 3, the amount of gas leaking from one zone to the other is very small, so that its impact on the gas characteristics of the space it flows into is negligible.

[0040] In the structure of the double-layer centrifuge device 1 shown in the figure, the refrigeration zone 2 includes two parts located in the upper and lower layers, namely the first refrigeration partition 21 located in the upper layer (labeled as...). Figure 2 (middle) and the second cooling zone 22 located in the lower part (marked in Figure 4 middle).

[0041] Figure 2 It shows Figure 1 The upper part of the centrifuge device 1 with a double-layer structure is shown, which mainly shows the first refrigeration zone 21 located in the upper part of the refrigeration zone 2 and the structure and arrangement of the components arranged in the first refrigeration zone 21.

[0042] In the upper portion, the first refrigeration sub-zone 21 is separated from the non-refrigeration area 3 by the first partition 51. As shown in the figure, the refrigeration area 2 is located at one side of the centrifugal device 20 (the right side in the figure), and the non-refrigeration area 3 is located at the other side of the centrifugal device 20 opposite to the first refrigeration sub-zone 21. The first partition 51 is arranged between the non-refrigeration area 3 and the first refrigeration sub-zone 21, and extends from the housing 10 to the outer peripheral surface of the centrifugal device 20. For example, in the exemplary structure shown in the figure, the first partition 51 includes two parts, which extend from the inner walls of the front and rear sides of the housing 10 to the outer peripheral surface of the centrifugal device 20, thereby separating the non-refrigeration area 3 and the first refrigeration sub-zone 21, so that the gas in the first refrigeration sub-zone 21 cannot or substantially cannot flow into the non-refrigeration area 3.

[0043] The first partition 51 can be a metal plate, a foam material, or a combination of a metal plate and a foam material, which can be selected according to the required characteristics of the first partition 51. For example, the metal plate can be selected as a steel plate, and the foam material can be selected as a PUR material, an EVA material, etc. For example, in the structure shown in the figure, the distance between the rear side plate (the lower side in the figure) of the housing 10 and the centrifugal device 20 is large, and the first partition 51 extending therebetween needs to have a certain structural strength, so the first partition 51 can be made of a metal plate or a combination of a metal plate and a foam material. The distance between the front side plate (the upper side in the figure) of the housing 10 and the centrifugal device 20 is short, or in other words, the two are very close, so from the perspective of cost saving, the first partition 51 arranged therebetween can be made of only a foam material. Figure 2 Figure 2 Figure 2

[0044] The refrigeration device 30, in particular the condenser 31, the compressor 32, the first refrigerant pipeline 33, and the second refrigerant pipeline 34 of the refrigeration device 30 are located in the first refrigeration sub-zone 21, and the inlet of the second refrigerant pipeline 34 into the centrifugal device 20 is also located in the first refrigeration sub-zone 21. Specifically, the condenser 31 and the compressor 32 of the refrigeration device 30 and the centrifugal device 20 are supported on the first base plate 16 of the upper portion.

[0045] A first air inlet 11 is formed on the portion of the housing 10 corresponding to the first refrigeration sub-zone 21, which is used to introduce external air flow into the first refrigeration sub-zone 21. The first air inlet 11 is arranged close to the condenser 31, so that the air introduced into the first refrigeration sub-zone 21 flows through the condenser 31, which can be cooled by the condenser 31. Preferably, a condenser fan 35 is also arranged in the first refrigeration sub-zone 21, which is installed on the condenser 31 to facilitate the suction of external air into the first refrigeration sub-zone 21. ​​​

[0046] A first air outlet 12 is also formed in the portion of the housing 10 corresponding to the first refrigeration zone 21, which is preferably located close to the compressor 32. In this way, the air flowing into the first refrigeration zone 21 can flow through the compressor 32 to cool the compressor 32.

[0047] Figure 3 Another view of the upper portion of the centrifuge apparatus 1 is shown, in which the structure and arrangement of the components in the non-refrigeration zone 3 are mainly displayed. Electronic devices including circuit boards, switches, etc. are arranged in the non-refrigeration zone 3. A second air inlet 13 and a second air outlet 14 are formed in the portion of the housing 10 corresponding to the non-refrigeration zone 3, through which external air can flow into the non-refrigeration zone 3 and out of it. Preferably, the second air inlet 13 and the second air outlet 14 are arranged at the positions of the front and rear side plates of the housing 10 shown in the figure, respectively, to allow air to sufficiently flow through the internal space of the non-refrigeration zone 3 to cool the electronic devices 60 located therein.

[0048] Preferably, an electronic device fan 61 is also arranged in the non-refrigeration zone 3, which promotes the suction of air into the non-refrigeration zone 3 and the flow of air through the electronic devices 60 to sufficiently cool them.

[0049] Since the first partition 51 is arranged between the first refrigeration zone 21 and the non-refrigeration zone 3, even if refrigerant leakage occurs in the refrigeration device 30 in the first refrigeration zone 21, the leaked refrigerant is limited within the scope of the first refrigeration zone 21 and does not or rarely flows into the non-refrigeration zone 3, thereby reducing the risk of explosion caused by the contact between the sparks possibly occurring in the electronic devices 60 and the refrigerant.

[0050] It is to be noted that the electronic devices 60 have relatively small heat generation, and the heat dissipation requirement of the electronic devices 60 can be met by relying on the convective heat exchange of the air sucked from the outside.

[0051] Figure 4 Another view of the upper portion of the centrifuge apparatus 1 is shown, in which the structure and arrangement of the components in the non-refrigeration zone 3 are mainly displayed. Electronic devices including circuit boards, switches, etc. are arranged in the non-refrigeration zone 3. A second air inlet 13 and a second air outlet 14 are formed in the portion of the housing 10 corresponding to the non-refrigeration zone 3, through which external air can flow into the non-refrigeration zone 3 and out of it. Preferably, the second air inlet 13 and the second air outlet 14 are arranged at the positions of the front and rear side plates of the housing 10 shown in the figure, respectively, to allow air to sufficiently flow through the internal space of the non-refrigeration zone 3 to cool the electronic devices 60 located therein. Figure 1The structure of the lower portion of the centrifuge apparatus 1 in which the centrifuge motor 40 is positioned, particularly supported on the second base plate 17 of the lower portion. A second partition 52 is provided in the second refrigeration zone 22, which is preferably provided around the centrifuge motor 40. Also, the second partition 52 is further provided to extend from the first base plate 16 of the upper portion to the second base plate 17 of the lower portion. In this way, the second refrigeration zone 22 surrounding the centrifuge motor 40 is formed by the second partition 52, and the second partition 52 at least separates the second refrigeration zone 22 from the non-refrigeration area 3. It is also noted that the second partition 52 can be fixed to either of the first base plate 16 and the second base plate 17, but can also only be in contact with the first base plate 16 and the second base plate 17, but not fixed or connected to them.

[0052] Similar to the first partition 51, the second partition 52 can also be made of a metal plate, a foam material, or a combination thereof.

[0053] Returning to Figure 2 It can be seen from the above that a third air inlet 15 is provided on the portion of the first base plate 16 located on the side of the first refrigeration zone 21, which is, for example, a through opening provided on the first base plate 16, thereby connecting the first refrigeration zone 21 and the second refrigeration zone 22 together. In Figure 4 The position of the second refrigeration zone 22 corresponding to the third air inlet 15 is indicated in

[0054] By providing the third air inlet 15, the cooling air in the first refrigeration zone 21 is allowed to flow into the second refrigeration zone 22 via the third air inlet 15, and then flow around the centrifuge motor 40 to cool the centrifuge motor 40.

[0055] The air flow circulation path for cooling the components of the centrifuge apparatus 1 will be described in detail below.

[0056] As Figure 2 shown, external air is drawn into the first refrigeration zone 21 of the refrigeration area 2 via the first air inlet 11, for example, by the action of the condenser fan 35. The drawn-in air first flows through the condenser 31 and is cooled. Then, part of the cooled air flows to the compressor 32 to cool the compressor 32, and then flows out from the first air outlet 12.

[0057] Another part of the air flows into the second refrigeration zone 22 via the third air inlet 15, and as Figure 4The air flows around the centrifugal motor 40 as shown, allowing sufficient contact between the air and the centrifugal motor 40 for adequate cooling. After heat exchange with the centrifugal motor 40, the cooled air exits from the third air outlet 41.

[0058] like Figure 3 As shown, under the action of, for example, the electronic device fan 61, outside air flows into the non-cooled area 3 through the second air inlet 13, and after exchanging heat with the electronic device 60 to cool the electronic device 60, the air flows out through the second air outlet 14.

[0059] The exemplary structure of the centrifuge equipment of this application has been described in detail above. Those skilled in the art will recognize that various obvious modifications, variations, and recombinations can be made based on the above disclosure, and these are all within the scope of this application.
