[0067] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0068] The core of this application is to provide a high-flux heating device and a control method thereof.

[0069] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0070] High-temperature heating is a common experimental requirement in materials science, chemical synthesis, biological experiments, and industrial production. The high-throughput heating device described in this application is particularly suitable for experimental environments that require high-temperature heating and process a large number of samples of varying types. This device can effectively prevent sample contamination, achieve high-throughput processing, and provide precise temperature control.

[0071] This embodiment provides a high-flux heating device. Figure 1 A schematic diagram of a high flux heating device provided in an embodiment of the present application is shown in FIG. Figure 1 Shown, including:

[0072] Heater fixture 1, heater 2, sample stage 3 for placing multiple independent samples, sample stage moving module, controller;

[0073] The heater 2 is fixed by the heater fixture 1; the sample stage 3 is arranged below the heater 2 and does not contact the heater 2; the sample stage moving module is connected to the sample stage 3; the controller is connected to the heater 2 and the sample stage moving module;

[0074] The controller controls the movement of the sample stage moving module, driving the sample stage 3 to move, so that one or more target samples to be heated on the sample stage 3 are successively located under the heater 2; the controller controls the heater 2 to heat and generate heat, which is transferred to the sample to be heated on the sample stage 3 through thermal radiation.

[0075] The heater fixture 1 is typically constructed of metal and graphite components and is used to secure and stabilize the heater 2. Preferably, the heater fixture 1 is secured to the heater 2 with screws, ensuring stability and ease of replacement. This embodiment does not limit the specific material type of the heater, but the heater must be a high-temperature resistant and conductive material, such as graphite film, carbon felt, graphite boat, tungsten boat, molybdenum boat, nickel foam, etc.

[0076] Sample stage 3 is positioned below heater 2, avoiding direct contact. Heat is transferred via thermal radiation, minimizing contamination risk. This embodiment does not limit the number of samples that can be heated simultaneously, nor does it limit the number of heaters 2. This can be configured based on experimental needs. For example, heater 2 can heat 10 samples simultaneously, heating the next group of 10 samples after the current 10 samples are heated. Alternatively, samples can be heated individually.

[0077] Joule heating is the process by which electrical energy is converted into thermal energy when current passes through a conductor. In ultrafast high-temperature heating devices, current passing through a resistive material generates Joule heating, rapidly heating the sample to the desired temperature. Radiative heating is a non-contact heating method that uses electromagnetic waves to transfer heat from the heat source to the sample. This method eliminates the need for a medium, avoids contamination, and ensures uniform temperature, making it suitable for high-temperature material processing and precision experiments.

[0078] The material of the sample stage 3 for placing multiple independent samples is not limited, but it needs to be a high-temperature resistant and easily machined material to ensure stability in long-term high-temperature operation, such as ceramics, carbon materials, metal materials, glass, etc.

[0079] The sample stage 3 can be either a flat plate or a well plate, and can accommodate multiple samples. Well plate sample stages can be shaped in a variety of shapes, including but not limited to rectangular, circular, and polygonal arrays. Figure 2(a) illustrates a circular array sample stage, Figure 2(b) illustrates a hexagonal array sample stage, and Figure 2(c) illustrates a rectangular array sample stage. In practical applications, the choice can be made based on actual needs.

[0080] In addition, no matter whether it is a flat plate sample stage 3 or a well plate sample stage 3 , the arrangement positions of the samples to be heated on the sample stage can be regular or irregular.

[0081] Preferably, each well can independently control temperature and time. Preferably, a 5×12 rectangular array design is used, which can accommodate at least 60 samples. The rectangular array sample stage facilitates regular movement and easy control of the number of samples heated simultaneously. The fixed number of wells in each row facilitates row-by-row heating by the heater.

[0082] The sample stage moving module is used to move the sample stage 3 so that the target sample to be heated is located under the heater 2 to achieve heating. A high-precision motion platform combined with a position sensor can ensure accurate positioning.

[0083] The controller receives the heating parameters set by the user, controls the sample stage moving module and heater 2, and realizes the automated heating process.

[0084] Under the control of the controller, heater 2 generates heat according to the set temperature and time parameters. Driven by the sample stage movement module, sample stage 3 is precisely positioned at the specified location for heating. The user sets the heating parameters through the computer, and the controller automatically executes the heating and movement instructions.

[0085] The number and layout of the slots on the sample stage 3 can be adjusted according to experimental requirements. The sample stage movement module can use a robotic arm to further improve the level of automation.

[0086] In addition, depending on the specific working experimental environment requirements, if a vacuum or specific gas-filled environment is required, a gas control system can be added to meet specific experimental conditions. If rapid cooling is required, a rapid cooling system such as a liquid nitrogen quenching device can be added.

[0087] With the high-throughput heating device provided by the embodiments of the present application, the sample to be heated is placed on a sample stage, which supports the placement of multiple independent samples to be heated. The controller controls the movement of the sample stage movement module so that one or more target samples to be heated on the sample stage are successively positioned below the heater. The heater efficiently transfers energy to heat the sample through thermal radiation, allowing parallel heating of multiple samples in a single experiment. The present application can efficiently process multiple types and large quantities of samples in a single heating process, significantly shortening the experimental cycle and improving data output efficiency, meeting diverse experimental needs and optimizing the overall experimental operation process.

[0088] According to the above embodiment, preferably, the method further comprises: a heater moving module;

[0089] The heater fixture 1 is arranged on the heater moving module, and the heater moving module is connected to the controller;

[0090] The controller controls the heater moving module to drive the heater 2 to move, so that the target sample to be heated on the sample stage 3 is moved below the heater 2 .

[0091] The heater movement module is used to move the heater according to the controller's instructions. When the sample stage is inconvenient to move, the heater movement module can be used to move the heating head to achieve heating. For example, if the sample to be heated is a liquid, to avoid spilling the sample when moving the sample stage, the heater movement module can be controlled to move Heater 2 so that the target sample on Sample Stage 3 is positioned below Heater 2.

[0092] According to the above embodiment, in order to flexibly adjust the heating area to adapt to the high-temperature heating treatment environment of samples of different sizes and shapes, in a specific embodiment, the heating head of the heater 2 is a heating head with adjustable size and shape.

[0093] The heater 2 can be made of any high-temperature-resistant and conductive material, and its heating head is designed to be detachable or adjustable.

[0094] The heating head is detachable, and heating heads of different shapes and sizes can be installed according to needs to meet special heating requirements.

[0095] Among them, the adjustable structure can be a heating head made of foldable material that is folded to form a protruding heating head, and the size of the protruding heating head can be changed according to different folding schemes; or the heating head adopts a variable diameter heating coil, and the coil expansion area is changed through a mechanical adjustment mechanism; or the heating head adopts a retractable structure, and the effective heating area is changed through electric or manual adjustment.

[0096] In addition, the circular / square heating head is interchangeable to meet the needs of different sample shapes.

[0097] This high-throughput heating device significantly improves the flexibility and adaptability of the device through the design of adjustable heating head size and shape, and can more widely meet different experimental needs.

[0098] According to the above embodiment, in an optional solution, the sample stage 3 includes a plurality of independent sample well slots; the size of the heating head of the heater 2 is such that it can cover the size of one independent sample well slot or the size of multiple independent sample well slots;

[0099] The controller controls the movement of the sample stage moving module or the heater moving module so that a target sample to be heated on the sample stage 3 is positioned point by point under the heating head of the heater 2 or multiple target samples to be heated on the sample stage 3 are positioned as a group under the heating head of the heater 2 one by one.

[0100] The sample stage 3 is made of high-temperature resistant and easily machined materials. The size of the heating head is precisely matched to a single well or a single row of wells. The heating head of the heater 2 can be the size of an independent sample well slot, achieving single-point heating. Figure 3 A schematic diagram of a point-by-point heating method provided in an embodiment of the present application; Figure 3 As shown in the figure, the size of the heating head is sufficient to cover an independent sample well slot, achieving point-by-point heating.

[0101] Figure 4 A schematic diagram of a row-by-row heating method provided in an embodiment of the present application; Figure 4 As shown, the size of the heating head is the size of a row of independent sample well slots, so that row-by-row heating is achieved, and the target samples to be heated are placed one by one under the heating head of the heater 2 for heating.

[0102] Figure 5 (a) is a schematic diagram of a heater shape provided in an embodiment of the present application, Figure 5 (b) is a schematic diagram of another heater shape provided in an embodiment of the present application, Figure 5 (c) is a schematic diagram of another heater shape provided in an embodiment of the present application, and Figure 5 (d) is a schematic diagram of another heater shape provided in an embodiment of the present application. As shown in the figures, the shape of the heating head of the heater is not limited and can be set according to actual needs. In addition, the size of the heating head can also be a heating head that can cover the size of two, three, or other independent sample well slots, which can be set according to actual heating needs.

[0103] As an optional solution, in the above-mentioned high-flux heating device, the heater fixture 1 includes two clamping arms; each of the two clamping arms is provided with an electrode;

[0104] One end of the two electrodes is connected to the heater 2 , and the other end of the two electrodes is connected to the power supply; the power management system of the power supply is connected to the controller.

[0105] In this embodiment, the electrodes of the heater are arranged on the two clamping arms of the heater clamp 1 , and the controller controls the heating temperature of the heater by controlling the current and voltage of the electrodes.

[0106] According to the above embodiment, the sample stage moving module is a key component of the high-throughput heating device. It is responsible for accurately controlling the position of the sample stage 3 to achieve point-by-point or row-by-row heating of the sample. In an optional solution, the sample stage moving module includes a sample stage connector 4 and a three-dimensional motion device; the three-dimensional motion device includes: an X-axis adjustment device 6, a Y-axis adjustment device 7, and a Z-axis adjustment device 5;

[0107] One end of the sample stage connecting member 4 is fixedly connected to the sample stage 3, and the other end of the sample stage connecting member 4 is rigidly connected to the moving parts of the X-axis adjusting device 6, the Y-axis adjusting device 7, and the Z-axis adjusting device 5;

[0108] The X-axis adjustment device 6 or the Y-axis adjustment device 7 is fixedly connected to the bottom of the housing, and the X-axis adjustment device 6 is connected to the Y-axis adjustment device 7; the Z-axis adjustment device 5 is vertically connected to the X-axis adjustment device 6 and the Y-axis adjustment device 7, and is arranged at the bottom of the sample stage connector 4;

[0109] The three-dimensional motion device drives the sample stage 3 to move along the X direction, Y direction, and Z direction through the X-axis adjustment device 6, the Y-axis adjustment device 7, and the Z-axis adjustment device 5, so that the target sample to be heated on the sample stage 3 is located below the heating head of the heater 2.

[0110] The sample stage connector 4 acts as a bridge, with one end fixedly connected to the sample stage 3 and the other end rigidly connected to the moving components of the three-dimensional motion mechanism. This ensures that the sample stage 3 can be precisely positioned as the three-dimensional motion mechanism moves. The connection between the sample stage connector 4 and the sample stage 3 must be strong and reliable to withstand the thermal and mechanical stresses that may be generated during heating. Furthermore, a rigid connection to the moving components of the three-dimensional motion mechanism ensures accurate and stable transmission.

[0111] The three-dimensional motion device is composed of an X-axis adjustment device 6, a Y-axis adjustment device 7 and a Z-axis adjustment device 5, and is responsible for driving the sample stage 3 to move in three-dimensional space.

[0112] The X-axis adjustment device 6 controls the movement of the sample stage 3 in the horizontal X direction, and the Y-axis adjustment device 7 controls the movement of the sample stage 3 in the horizontal Y direction; wherein, either the X-axis adjustment device 6 or the Y-axis adjustment device 7 is fixedly connected to the bottom of the shell, the X-axis adjustment device 6 is connected to the Y-axis adjustment device 7, and the Y-axis adjustment device 7 works together with the X-axis adjustment device 6 to realize the movement of the sample stage 3 to any position on the horizontal plane.

[0113] The Z-axis adjustment device 5 controls the movement of the sample stage 3 in the vertical Z direction, is vertically connected to the X-axis adjustment device 6 and the Y-axis adjustment device 7, and is arranged at the bottom of the sample stage connector 4 to realize the lifting and lowering of the sample stage 3 in the vertical direction.

[0114] When point-by-point heating is required, the three-dimensional motion device, according to the instructions of the controller, precisely cooperates with the X-axis, Y-axis and Z-axis adjustment devices 5 to position the target samples to be heated one by one under the heating head of the heater 2 for heating.

[0115] For the row-by-row heating mode, the three-dimensional motion device moves the multiple rows of sample wells of the sample stage 3 in sequence along the Y-axis (or X-axis, depending on the specific design) to the bottom of the heating head for heating according to the set order.

[0116] The sample stage moving module realizes the precise movement and positioning of the sample stage 3 in three-dimensional space through the precise coordination of the sample stage connector 4 and the three-dimensional motion device, providing a strong guarantee for the efficient operation of the high-throughput heating device.

[0117] According to the above embodiment, the sample stage moving module of the high-flux heating device has specific design and functional features, which are mainly reflected in the X-axis adjustment device 6, the Y-axis adjustment device 7, and the Z-axis adjustment device 5. In an optional solution, the X-axis adjustment device 6 and the Y-axis adjustment device 7 are automatic adjustment devices; the Z-axis adjustment device 5 is a manual adjustment device;

[0118] The Z-axis adjustment device 5 includes: an anti-loosening locking mechanism and a spiral lifting adjustment mechanism; the anti-loosening locking mechanism is used to lock the position of the sample stage 3 after the adjustment is completed, and the spiral lifting adjustment mechanism is used for vertical lifting adjustment;

[0119] The X-axis adjustment device 6 and the Y-axis adjustment device 7 are connected to a controller, and the controller controls the sample stage 3 to move along the X direction and the Y direction.

[0120] Both the X-axis adjustment device 6 and the Y-axis adjustment device 7 are automatic adjustment devices, meaning they automatically and precisely control the movement of the sample stage 3 in the horizontal plane (XY plane) according to a preset program or controller instructions. They receive signals from the controller to adjust the position of the sample stage 3 in real time. This connection ensures high precision and efficiency during the heating process.

[0121] The automatically adjustable X-axis and Y-axis devices enable the sample stage 3 to be moved quickly and accurately under the heating head of the heater 2, supporting point-by-point or line-by-line heating modes, thereby improving the flexibility and throughput of the experiment.

[0122] The Z-axis adjustment device 5 is different from the X-axis and Y-axis devices in that it is a manual adjustment device, which means that the user needs to manually adjust the position of the sample stage 3 in the vertical direction (Z direction).

[0123] The Z-axis adjustment device 5 includes a locking mechanism and a screw-type adjustment mechanism. The locking mechanism is used to lock the position of the sample stage 3 after adjustment, preventing it from moving due to vibration or thermal stress during the heating process. The screw-type adjustment mechanism provides precise vertical lifting function.

[0124] The manually adjustable Z-axis device allows the user to precisely adjust the distance between the sample stage 3 and the heater 2 according to actual needs to adapt to the heating requirements of different samples.

[0125] The combination of automatically adjustable X- and Y-axis mechanisms and a manually adjustable Z-axis ensures high precision and automation of the heating process while providing the flexibility of manual intervention. This design allows the device to adapt to different experimental needs and operating habits.

[0126] Although the Z-axis is manually adjustable, its operation is relatively simple and intuitive. The user only needs to rotate the screw lift mechanism to achieve precise adjustment. At the same time, the anti-loosening locking mechanism design also avoids safety hazards during adjustment.

[0127] According to the above embodiment, in order to ensure the stability and reliability of the device in a high temperature working environment, in an optional solution, it further includes: a water cooling system, a gas control system, and a cavity 8;

[0128] The cavity 8 is a closed space, and the heater fixture 1, heater 2, sample stage 3, and sample stage moving module are arranged inside the cavity 8; the outside of the cavity 8 is connected to the water cooling system and the gas control system;

[0129] The controller is connected to the water cooling system and the gas control system; the controller controls the water cooling system to adjust the temperature inside the cavity 8 and controls the gas control system to adjust the gas environment conditions inside the cavity 8.

[0130] Cavity 8 is a sealed space designed to provide a stable and uniform operating environment for the internal components. The heater fixture 1, heater 2, sample stage 3, and sample stage movement module are all located within cavity 8. This sealed structure reduces the impact of external heat on the internal heating process and prevents internal high temperatures from radiating heat to the outside of the device and the surrounding environment.

[0131] The water cooling system typically includes components such as a chiller, piping, and valves. Circulating cooling water absorbs and removes excess heat generated by heating within cavity 8, maintaining the internal temperature within a stable range. The absorbed heat is dissipated into the air through the chiller, and the cooled water is then recirculated into cavity 8, forming a closed-loop control system.

[0132] The controller is responsible for receiving feedback signals from temperature sensors and other sources, and controlling the operation of the water cooling system according to preset logic, including the start and stop of the chiller, the flow rate and temperature of the cooling water, etc.

[0133] The controller is connected to the water cooling system through electrical signals to control the operating parameters of the water cooling system.

[0134] The controller is also connected to the gas control system through electrical signals to control the gas pumping and deflation operations of the gas control system to maintain the gas environment conditions inside the cavity 8.

[0135] The gas control system is mainly used to maintain the vacuum condition inside the cavity 8 to eliminate or reduce the influence of air on the heating process, especially in experiments requiring high purity or special atmosphere environments.

[0136] In addition, preferably, the gas control system unit can also be connected to different types of gas cylinders for filling inert gas to provide different cavity environments, such as vacuum, air, nitrogen, argon and other gas environments.

[0137] During the heating process, heater 2 generates high temperatures, which are transferred to the sample on sample stage 3 through thermal radiation. Simultaneously, a water cooling system continuously circulates cooling water, absorbing and removing excess heat within the chamber to maintain a stable temperature. The gas control system maintains a vacuum or other gas environment within the chamber, depending on experimental requirements. This ensures stable operation of the high-throughput heating device in high-temperature, vacuum, or specialized atmospheres, improving experimental accuracy and reliability. Furthermore, precise temperature control and heat dissipation management reduce energy consumption and extend the life of the equipment.

[0138] According to the above embodiment, in an optional solution, it further includes: a temperature measuring window 9, an infrared temperature measuring device 10;

[0139] The temperature measuring window 9 is provided at the top of the cavity 8; the infrared temperature measuring device 10 is provided outside the cavity 8 and is aligned with the center position of the heater 2 through the temperature measuring window 9;

[0140] The infrared temperature measuring device 10 is connected to the controller, and the controller receives the temperature signal collected by the infrared temperature measuring device 10 .

[0141] The temperature measuring window 9 is provided at the top of the cavity 8, providing an unobstructed observation channel for the infrared temperature measuring device 10. The main function of the temperature measuring window 9 is to allow the infrared rays of the infrared temperature measuring device 10 to penetrate directly to the center of the heater 2, thereby achieving accurate measurement of the temperature of the heater 2.

[0142] The infrared temperature measuring device 10 is arranged outside the cavity 8, and forms an infrared temperature measuring optical path with the heater 2 through the temperature measuring window 9. The infrared temperature measuring device 10 is connected to the controller and transmits the measured temperature data to the controller in real time.

[0143] Infrared temperature measurement device 10 utilizes the principle of infrared radiation to measure the temperature of heater 2 in a non-contact manner. This measurement method is not only highly accurate but also avoids the potential safety hazards associated with direct contact with heater 2. By providing real-time feedback on temperature data, the controller can dynamically adjust the heating power of heater 2 according to a preset temperature curve or heating program, ensuring that the sample reaches the desired temperature during heating and maintaining temperature stability and uniformity.

[0144] The combined use of temperature measuring window 9 and infrared temperature measuring device 10 ensures accurate measurement of the temperature of heater 2. The non-contact measurement method of infrared temperature measuring device 10 reduces sources of error and improves measurement accuracy. This non-contact temperature measurement method avoids the potential safety hazards of direct contact with the high-temperature heater 2, thereby improving the safety performance of the device.

[0145] The temperature measurement module in this solution realizes real-time and accurate measurement of the temperature of the heater 2 through the precise combination of the temperature measurement window 9 and the infrared temperature measurement device 10, providing strong support for the performance improvement of the high-flux heating device.

[0146] In a specific embodiment, it further includes: an observation window 11;

[0147] The observation window 11 is provided at the front of the chamber 8 , and the observation range of the observation window 11 faces the heater 2 and the sample stage 3 .

[0148] It is convenient for the experimenter to visually monitor the sample heating process in real time, so that the experimenter can observe the experimental phenomenon intuitively. The observation range of the observation window 11 is not limited in this embodiment, and a wider range can be observed. An observation window with adjustable observation direction can also be set according to needs.

[0149] This embodiment also provides a control method for a high-flux heating device, which is applied to the high-flux heating device. The high-flux heating device includes: a heater fixture 1, a heater 2, a sample stage 3 for placing multiple independent samples, a sample stage moving module, and a controller. The heater 2 is fixed by the heater fixture 1; the sample stage 3 is arranged below the heater 2 and does not contact the heater 2; the sample stage moving module is connected to the sample stage 3; and the controller is connected to the heater 2 and the sample stage moving module.

[0150] like Figure 6 As shown, the method includes:

[0151] S11: receiving a heating instruction;

[0152] S12: Controlling the sample stage moving module to move, driving the sample stage to move, so that one or more target samples to be heated on the sample stage are successively positioned under the heater;

[0153] S13: Control the heater to generate heat, and transfer the heat to the sample to be heated on the sample stage through thermal radiation.

[0154] In this embodiment, step S11 of receiving a heating instruction indicates that the system has received a heating instruction from the user. This can be achieved through the device's operating interface, remote control system, or other means. The user can customize the heating temperature and heating time for different hole positions.

[0155] In step S12, the controller controls the sample stage moving module to move so that the target sample to be heated on the sample stage 3 is located below the heater 2. After receiving the heating instruction, the controller sends a signal to the sample stage moving module to drive it to move the sample stage 3 so that the target sample to be heated (i.e., the hole where the sample to be heated is located) is accurately positioned below the heater 2.

[0156] The target sample to be heated is the user-specified or preset well where the sample to be heated is located. This ensures that only the sample to be heated is placed within the radiation range of the heater 2, improving the accuracy and efficiency of heating.

[0157] In step S13, heater 2 generates heat, which is then transferred to the sample on stage 3 via thermal radiation. Once the target sample is in place, the controller controls heater 2 to begin heating, generating heat. This heat is transferred to the sample on stage 3 via thermal radiation, achieving non-contact heating.

[0158] The user sends a heating instruction through the operation interface or remote control system. After receiving the instruction, the controller controls the sample stage moving module to move the sample stage 3 so that the target sample to be heated is positioned under the heater 2. The controller controls the heater 2 to start heating, and the heat generated is transferred to the sample to be heated through thermal radiation. The heater efficiently transfers energy to heat the sample through thermal radiation, so that parallel heating treatment of multiple samples can be completed in a single experiment. The present application can efficiently process multiple types and a large number of samples in a single heating process, significantly shorten the experimental cycle and improve data output efficiency, meet the needs of diverse experiments, and optimize the overall experimental operation process.

[0159] Furthermore, the high-flux heating device further comprises: a heater moving module; the heater fixture 1 is arranged on the heater moving module, and the heater moving module is connected to the controller;

[0160] The method also includes:

[0161] The heater moving module is controlled to drive the heater 2 to move so that the target sample to be heated on the sample stage 3 is positioned below the heater 2 .

[0162] The heater moving module is used to move the heater according to the instructions of the controller. When the sample stage is inconvenient to move, the heater head can be moved by the heater moving module to achieve heating.

[0163] The controller independently or collaboratively controls the sample stage motion module and the heater motion module, enabling two selectable motion modes: In the first, the sample stage motion module drives the sample stage along a preset path while the heater remains stationary, precisely positioning the target sample within the heating zone. In the second, the heater motion module dynamically adjusts the heater's position in three dimensions while the sample stage remains stationary, actively moving the heater to cover different areas of the target sample. These two modes can be switched freely or operated collaboratively to accommodate diverse experimental needs.

[0164] According to the above embodiment, in an optional solution, the size of the heating head of the heater 2 is such that it can cover the size of one independent sample well slot or the size of multiple independent sample well slots;

[0165] Correspondingly, controlling the sample stage moving module to move drives the sample stage 3 to move so that one or more target samples to be heated on the sample stage 3 are successively positioned below the heater 2 , including:

[0166] When the size of the heating head of the heater 2 is large enough to cover an independent sample well slot, the sample stage moving module is controlled to move or the heater moving module is controlled to move so that a target sample to be heated on the sample stage 3 is positioned point by point under the heating head of the heater 2;

[0167] When the size of the heating head of heater 2 is large enough to cover multiple independent sample hole slots, the multiple target samples to be heated on the sample stage 3 are treated as a group, and the sample stage moving module is controlled to move or the heater moving module is controlled to move so that each group of target samples to be heated is located under the heating head of heater 2 one by one.

[0168] In this embodiment, the heating head is sized to cover one or multiple independent sample well slots, improving experimental throughput and data output speed. The design of the heating head of Heater 2 allows the device to flexibly switch between single-point heating and multi-point heating modes to meet different experimental needs, allowing for more concentrated and efficient energy utilization, and improving heating efficiency and uniformity.

[0169] The controller also precisely controls sample movement and heating by receiving real-time feedback from the sample stage movement module. It also schedules the heating sequence and duration of samples based on preset heating parameters and experimental requirements, ensuring efficient experiment execution.

[0170] Preferably, the high-flux heating device further comprises: an infrared temperature measuring device 10; and the method further comprises:

[0171] receiving a surface temperature signal of the heater collected by the infrared temperature measuring device 10;

[0172] The heating temperature of the heater is adjusted according to the temperature signal.

[0173] According to the above embodiment, this can be achieved by providing a temperature measuring window 9 at the top of the cavity 8, thereby providing an unobstructed observation channel for the infrared temperature measuring device 10. The main function of the temperature measuring window 9 is to allow the infrared rays of the infrared temperature measuring device 10 to penetrate directly to the center of the heater 2, thereby achieving accurate measurement of the temperature of the heater 2.

[0174] The infrared temperature measuring device 10 is arranged outside the cavity 8, and forms an infrared temperature measuring optical path with the heater 2 through the temperature measuring window 9. The infrared temperature measuring device 10 is connected to the controller and transmits the measured temperature data to the controller in real time.

[0175] After receiving the temperature signal, the controller adjusts the heating temperature of the heater by adjusting the current and voltage.

[0176] According to the above embodiment, in order to achieve accurate heating of each target sample to be heated in the sample stage 3, in an optional solution, controlling the heater 2 to generate heat includes:

[0177] Receive the target heating temperature and target heating time corresponding to each target sample to be heated;

[0178] The heater 2 is controlled to heat the current target sample to be heated to the corresponding target heating temperature and for the target heating time.

[0179] The controller first receives the target heating temperature and target heating time set by the user or a preset program for each target sample to be heated. These target heating temperatures and target heating times may vary depending on factors such as experimental requirements and sample characteristics.

[0180] The controller controls the heater 2 to heat the current target sample to be heated to the corresponding target heating temperature and the target heating time by adjusting the current, voltage and other parameters of the heater 2 according to the received target heating temperature and target heating time.

[0181] This embodiment allows different heating temperatures and times to be set for each target sample to be heated, thereby improving the flexibility and accuracy of the experiment. The controller accurately controls the heating process of heater 2, ensuring that each target sample to be heated reaches the preset target heating temperature.

[0182] During the heating process, the controller monitors the actual temperature of the heater 2 in real time through the infrared temperature measuring device, and makes real-time adjustments based on the deviation between the actual temperature and the target temperature to ensure the stability and accuracy of the heating process.

[0183] By setting a different heating temperature for each target sample and precisely controlling the heating process, the accuracy and repeatability of the experiment are improved. Users can flexibly set heating parameters according to experimental requirements to meet diverse experimental needs.
