However, there is a risk of sample leakage within the thermostatic chamber. If leakage occurs, the entire circulation loop will be contaminated. Furthermore, the temperature regulating device is complex and difficult to clean. Utility Model Content

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] Please see Figure 1 This application provides a temperature control system 10, which is applied to a sample processing device 1. The temperature control system 10 includes a sample processing container 110, a first circulation pipeline 120, a temperature regulating device 130, and a second circulation pipeline 140. The sample processing container 110 is connected to the first circulation pipeline 120, the temperature regulating device 130 is connected to the second circulation pipeline 140, and the first circulation pipeline 120 and the second circulation pipeline 140 are separated and thermally connected.

[0030] In this embodiment, the sample processing container 110 has a storage cavity 111 for accommodating and storing samples. The sample processing container 110 can be made of metal or plastic to facilitate cleaning. This embodiment does not limit the specific form of the sample. For example, in one embodiment, the sample can be a biological sample, and in another embodiment, the sample can be a viral sample, etc., depending on the actual situation. Similarly, this embodiment does not limit the specific structure of the storage cavity 111. For example, it can be a square cavity. In some other embodiments, the specific structure of the storage cavity 111 can also be set to a corresponding ellipsoidal or circular structure, etc., depending on the actual situation.

[0031] The first circulation pipeline 120 is used to contain the first heat exchange liquid. In this embodiment, the specific form of the first heat exchange liquid is not limited. For example, it can be distilled water or biological saline solution. The specific form can be limited according to the actual situation. In this embodiment, the first heat exchange liquid in the first circulation pipeline 120 is connected to the storage cavity 111 so that the first heat exchange liquid can enter and leave the storage cavity 111, thereby changing the temperature in the storage cavity 111.

[0032] The second circulation pipe 140 is used to contain the second heat exchange fluid. This embodiment does not limit the specific form of the second heat exchange fluid. For example, the second heat exchange fluid can be a liquid with a low specific heat capacity, which allows for faster temperature changes within the entire second circulation pipe 140. This enables faster heat transfer to the first circulation pipe 120 for heat transfer with the first circulation pipe 120, and thus allows for more rapid control of temperature changes within the storage chamber 111. For example, in one embodiment, the heat exchange fluid can be an antifreeze containing ethylene glycol. It is understood that since liquids with low specific heat capacity are usually toxic, water can also be used directly as the second heat exchange fluid in some embodiments, which is safer and more environmentally friendly. It is understood that in this embodiment, the first circulation pipe 120 and the second circulation pipe 140 can also be made of metal or plastic to facilitate cleaning of the sample processing container 110.

[0033] The temperature regulating device 130 is used to cool and heat the second heat exchange fluid in the second circulation pipe 140. It should be noted that, in one embodiment, the temperature regulating device may only cool the second heat exchange fluid in the second circulation pipe 140; in other embodiments, the temperature regulating device may only heat the second heat exchange fluid in the second circulation pipe 140. In a specific embodiment, the refrigeration device may be a chiller, specifically a room temperature chiller or a low-temperature industrial chiller.

[0034] It should be noted that the embodiments of this application do not limit the flow mode of the first heat exchange fluid and the second heat exchange fluid. The arrows in the figure only show one flow mode of the first heat exchange fluid and the second heat exchange fluid in this embodiment. In some other embodiments, the first heat exchange fluid and the second heat exchange fluid may also flow counterclockwise, or one of the first heat exchange fluid and the second heat exchange fluid may flow clockwise and the other may flow counterclockwise, etc. The specific settings can be made according to the actual situation.

[0035] The temperature control system 10 provided in this application embodiment sets up two independent first circulation pipes 120 and second circulation pipes 140. A temperature regulating device 130 is set on the second circulation pipe 140 to regulate the liquid temperature in the second circulation pipe 140. The liquid temperature in the first circulation pipe 120 is changed by heat exchange between the first circulation pipe 120 and the second circulation pipe 140. The first circulation pipe 120 is connected to the storage cavity 111, thereby changing the temperature in the storage cavity 111 by heat exchange. In this embodiment, the storage chamber 111 and the second circulation pipeline 140 are not interconnected, so that the liquid in the storage chamber 111 will not exchange with the liquid in the second circulation pipeline 140. Even if the sample in the storage chamber 111 leaks, it will not affect the temperature regulation device 130 on the second circulation pipeline 140. In addition, since the sample processing container 110 and the first circulation pipeline 120 are used to hold water for a long time and are in a low-temperature environment, moss and other dirt may slowly grow on the inner wall of the sample processing container 110 and the first circulation pipeline 120. This application separates the first circulation pipeline 120 and the second circulation pipeline 140, which can also prevent dirt in the first circulation pipeline 120 from entering the second circulation pipeline 140. This can solve the problem of inconvenient cleaning of the chiller caused by sample leakage and circulation water pollution in the current constant temperature chamber.

[0036] It should be noted that the thermal connection in this application refers to a connection method capable of heat exchange. This application does not limit the thermal connection method of the first circulation pipe 120 and the second circulation pipe 140. For example, in one embodiment, the first circulation pipe 120 and the second circulation pipe 140 can be in side-by-side contact to achieve heat exchange between the first heat exchange fluid in the first circulation pipe 120 and the second heat exchange fluid in the second circulation pipe 140. Besides the side-by-side contact method, the first circulation pipe 120 and the second circulation pipe 140 can also be thermally connected via a heat exchange device 150. In this embodiment, the temperature control system 10 further includes a heat exchange device 150. A portion of the heat exchange device 150 is connected to the first circulation pipe 120, and another portion of the heat exchange device 150 is connected to the second circulation pipe 140. That is, in this embodiment, the first circulation pipe 120 and the second circulation pipe 140 are separated from each other and thermally connected through the heat exchange device 150. The first heat exchange liquid in the first circulation pipe 120 can flow into the first area of ​​the heat exchange device 150, and the second heat exchange liquid in the second circulation pipe 140 can flow into the second area of ​​the heat exchange device 150. The first area and the second area are separated from each other to avoid cross-contamination between the first circulation pipe 120 and the second circulation pipe 140.

[0037] This application does not limit the specific structure and form of the heat exchange device 150. For example, it can be a plate heat exchanger, an immersed coil heat exchanger, a shell-and-tube heat exchanger, or a tube-and-tube heat exchanger. Taking the heat exchange device 150 as a plate heat exchanger as an example, the first region and the second region can be arranged in a cross-layered manner. This can increase the contact area between the first region and the second region, thereby improving the heat exchange efficiency and facilitating temperature control within the storage cavity 111.

[0038] In one embodiment, the temperature control system 10 may also have an insulation layer (not shown in the figure), wherein the insulation layer may be made of a sponge or foam type heat insulation material. It is understood that the surfaces of the first circulation pipe 120, the second circulation pipe 140, and the storage cavity 111 will all be in contact with the first heat exchange liquid or the second heat exchange liquid. Therefore, the temperature of the first heat exchange liquid and the second heat exchange liquid may be wasted because the temperature of the first heat exchange liquid or the second heat exchange liquid is transferred to the outside after passing through the first circulation pipe 120, the second circulation pipe 140, or the storage cavity 111. Therefore, in one embodiment, at least one of the outer surfaces of the first circulation pipe 120, the second circulation pipe 140, and the storage cavity 111 is provided with an insulation layer to reduce energy waste, reduce heat loss in the storage cavity 111, and prevent condensation on the outer surfaces of the first circulation pipe 120, the second circulation pipe 140, and the storage cavity 111.

[0039] It should be noted that the embodiments of this application do not limit the connection method between the insulation layer and the surfaces of the first circulation pipe 120, the second circulation pipe 140 and the storage cavity 111. For example, the insulation layer can be sprayed onto the surfaces of the first circulation pipe 120, the second circulation pipe 140 and the storage cavity 111, or the insulation layer can be pasted onto the surfaces of the first circulation pipe 120, the second circulation pipe 140 and the storage cavity 111. The specific choice can be made according to the actual structure of the insulation layer.

[0040] Furthermore, the temperature control system 10 provided in this application embodiment also includes a liquid level sensor 171. The liquid level sensor 171 is used to detect the liquid level in the storage cavity 111. It can be understood that the temperature control system 10 provided in this application embodiment is applied to the sample processing device 1, and therefore needs to be processed in a liquid environment. The liquid level sensor 171 can be used to detect the height of the liquid level, and then determine whether the sample to be processed is below the liquid surface, so as to ensure that the sample stored in the storage cavity 111 can be processed. In this embodiment, the liquid level sensor 171 can be any one of the following types: float type, float cylinder type, capacitive type, hydrostatic type, optical type, ultrasonic type, laser type, conductive type, diaphragm type, etc. It should be noted that this application embodiment does not limit the specific location and number of liquid level sensors 171 installed. The specific settings can be flexibly configured according to the sample to be processed. For example, in a specific embodiment, a conductive liquid level sensor 171 can be installed on the inner wall of the storage cavity 111.

[0041] In one embodiment, the temperature control system 10 may further include a temperature sensor 172, which is used to detect the temperature inside the storage cavity 111. In this embodiment, the temperature sensor 172 can be any type of thermocouple, thermistor, platinum resistance thermometer, infrared sensor, semiconductor sensor, etc. It should be noted that this application does not limit the specific type or location of the temperature sensor 172. For example, in one embodiment, the temperature sensor 172 can be placed below the liquid surface and used to detect the liquid temperature inside the storage cavity 111. In another embodiment, the temperature sensor 172 can be placed in the cavity area above the liquid surface and used to detect the cavity temperature inside the storage cavity 111. The specific configuration can be adjusted according to actual conditions. In a specific embodiment, a thermistor can be installed on the bottom wall 184 of the storage cavity 111 as the temperature sensor 172.

[0042] Furthermore, in one embodiment, the temperature control system may further include a control unit 173. A first water pump 191 is connected to the first circulation pipe 120 to drive the flow of liquid in the first circulation pipe 120, thereby enabling the first heat exchange liquid in the first circulation pipe 120 to exchange heat with the second heat exchange liquid in the second circulation pipe 140, thus improving the heat exchange efficiency between the first and second heat exchange liquids. A second water pump 192 is connected to the second circulation pipe 140 to drive the flow of liquid in the second circulation pipe 140. The principle and function of the second water pump 192 are similar to those of the first water pump 191, as detailed above. Temperature sensor 172, the first water pump 191, and the second water pump 192 are all communicatively connected to the control unit 173. The control unit 173 can acquire the temperature feedback from the temperature sensor 172 and control the operation of the first and second water pumps 191 and 192 to achieve heat exchange between the first and second heat exchange liquids, thereby changing and controlling the temperature within the storage chamber 111.

[0043] It should be noted that this application does not limit the specific structure and form of the first water pump 191 and the second water pump 192. For example, a positive displacement pump or a vane pump can be used. Furthermore, a water pump with a fixed flow rate or an adjustable speed can be used. This facilitates the control of the flow rate of the first heat exchange liquid in the first circulation pipeline 120 and the second heat exchange liquid in the second circulation pipeline 140, thereby facilitating the control of the heat transfer efficiency of the first heat exchange liquid and the second heat exchange liquid.

[0044] In another embodiment, the temperature regulating device 130 can also be connected to the control unit 173. In this case, the control unit 173 can control the temperature regulating device 130 to cool or heat the second heat exchange liquid in the second circulation pipeline 140 according to the temperature fed back by the temperature sensor 172, so as to achieve the effect of changing the temperature in the storage chamber 111.

[0045] Please also refer to Figure 2 and Figure 3 In one embodiment, the temperature control system 10 may further include a protective housing 180. The heat exchange device 150 and the first circulation pipeline 120 are installed within the protective housing 180. In a more specific embodiment, the sample processing container 110 is also installed within the protective housing 180. The protective housing 180 provides protection for the heat exchange device 150, the first circulation pipeline 120, and the sample processing container 110, preventing or reducing the impact of the external environment. In some embodiments, the control unit 173 may also be housed within the protective housing 180, similarly preventing or reducing the impact of the external environment.

[0046] The second circulation pipeline 140 includes a pipeline connector 181 fixed to the protective shell 180. The pipeline connector 181 is connected to the temperature regulating device 130. That is, in this embodiment, the second circulation pipeline 140 can be divided into two parts. One part is connected between the heat exchange device 150 and the pipeline connector 181, and the other part is connected between the temperature regulating device 130 and the pipeline structure. When the heat exchange device 150 needs to be cleaned or replaced, only the part of the second circulation pipeline 140 connected to it can be disassembled. This can further avoid or reduce the possibility of cross-contamination of the temperature regulating device 130. As mentioned above, in this embodiment, the first water pump 191 can be disposed inside the protective shell 180, and the second water pump 192 can be disposed outside the protective shell 180 and integrated into the temperature regulating device 130.

[0047] As mentioned above, this application does not limit the specific structure and form of the protective shell 180. For example, it can be a square protective shell 180, or it can be a protective shell 180 customized based on the installation environment, etc., and can be set according to the actual situation. In this embodiment, the protective shell 180 may have a first sidewall 182 and a second sidewall 183 arranged opposite to each other, and a bottom wall 184 connected to the bottom surface of the first sidewall 182 and the second sidewall 183. The pipe joint 181 can be set on the first sidewall 182, and the heat exchange device 150 and the first water pump 191 can be set on the bottom wall 184 and located close to the first sidewall 182. This can reduce the length of the part between the second circulation pipe 140 and the heat exchange device 150. It should be noted that this application does not limit the connection method between the pipe joint 181 and the first sidewall 182. For example, it can be a detachable connection such as a snap-fit, or a fixed connection such as welding, or it can be an integrally formed setting, and can be set according to the actual situation. Meanwhile, this application embodiment does not restrict the connection method between the heat exchange device 150 and the bottom wall 184 or the connection method between the first water pump 191 and the bottom wall 184. For example, it can be a fixed connection, which can prevent the heat exchange device 150 and the first water pump 191 from being displaced relative to the bottom wall 184, thereby preventing the first circulation pipe 120 or the second circulation pipe 140 from being disconnected.

[0048] The working principle of the temperature control system 10 provided in the embodiments of this application is as follows:

[0049] The control unit 173 can preset the temperature to T, and then manually or by using the control unit 173, set the temperature of the temperature regulating device 130 to T1. At this time, the temperature difference ΔT = T - T1.

[0050] The control unit 173 can control the first water pump 191 to work according to ΔT, so that the first heat exchange liquid circulates in the first circulation pipeline 120 and the storage chamber 111, and the first heat exchange liquid undergoes heat exchange in the heat exchange device 150 through temperature difference, thereby allowing the first heat exchange liquid to absorb or dissipate heat, and the temperature in the storage chamber 111 is dynamically maintained at T.

[0051] Specifically, the magnitude and sign of ΔT can be determined based on the environment in which the storage cavity 111 is located. For example:

[0052] When the room temperature is 25 degrees Celsius, the set temperature T is lower than the room temperature, and the temperature of the sample storage container will continue to rise when it is in operation, it can be determined that it is necessary to continuously absorb the heat emitted by the storage chamber 111, and the set value T1 of the temperature regulating device 130 is lower than T. △T is positive, and its size is determined according to the heat exchange heat and efficiency, and is generally set to 3 to 5 degrees Celsius.

[0053] When the room temperature is 25 degrees Celsius, the set temperature T is higher than the room temperature, and the temperature of the sample storage container will continue to drop when it is in operation, it can be determined that heat needs to be continuously supplied to the storage chamber 111. The set value T1 of the temperature regulating device 130 needs to be higher than T, and ΔT is negative. The value is determined according to the heat exchange heat and efficiency, and is generally set to 3 to 5 degrees Celsius.

[0054] Specifically, it can be determined whether to continuously replenish heat to the storage device or absorb heat based on the actual situation, thereby determining whether the temperature regulation device 130 should be turned on for cooling or heating, as well as the magnitude and sign of the temperature difference ΔT.

[0055] Please see Figure 4 This application also provides a sample processing device 1, which includes an ultrasonic sample processing system 20 and a temperature control system 10 as described above. The ultrasonic sample processing system 20 is used to process samples stored in a storage cavity 111 and located in a first heat exchange fluid. Since the sample processing device 1 provided in this application uses the temperature control system 10 described above, it can also solve the problem of inconvenient chiller cleaning caused by sample leakage in the constant temperature chamber leading to contamination of the circulating water circuit.

[0056] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
