Detailed Description
The present application is further described in conjunction with the drawings and detailed embodiments below to enable one skilled in the art to better understand and practice the application.
Referring to fig. 1, the radiation source device provided by the application aims to provide accurate calibration references for measurement equipment such as infrared thermal imagers, infrared thermometers and the like through an efficient and stable heat transfer mechanism. The device integrates various advanced technical elements including a heating surface 101, an axial flow pump 102, an eddy current temperature rise device 103, a ribbed radiator 104, a radiation surface 105, a temperature sensor 106 and a power unit 107, and forms a closed-loop temperature control system together.
The radiation source device mainly comprises a heating surface 101, an axial flow pump 102, an eddy current temperature rise device 103, a fin radiator 104, a radiation surface 105, a temperature sensor 106, a power unit 107 and the like. These components together achieve precise control of the temperature of the radiating surface 105 by means of a well-designed layout and connection.
The heating surface 101 is located on the rear side of the radiation surface 105 and is the source of heat generation. The interior of the device is designed with a plurality of smooth pipelines for accommodating and heating heat source liquid.
The axial flow pump 102 is responsible for driving the heat source liquid to circulate in the system, ensuring that heat is transferred evenly and quickly to the radiant surface 105. The axial flow pump
The eddy current temperature rising device 103 is used as a main provider of a heat source, converts electric energy into heat energy through the electromagnetic induction principle, and heats heat source liquid flowing through the eddy current temperature rising device.
The fin radiator 104 is located on the circulation path of the heat source liquid, and is used for absorbing and radiating excessive heat when the liquid flows through, so as to keep the stable operation of the system.
The radiation surface 105 faces the infrared measurement device to be calibrated, has the characteristic of high emissivity, and can simulate a real temperature distribution scene.
The temperature sensor 106 monitors the temperature of the heat source liquid and the radiation surface 105 in real time, providing accurate data support for temperature control.
The power unit 107 intelligently adjusts the power output of the eddy current Wen Shengqi and the axial flow pump 102 according to the feedback signal of the temperature sensor 106, so as to realize accurate control of the temperature of the radiation surface 105.
When the radiation source device is activated, the power unit 107 first supplies the electric energy to the eddy current temperature rising vessel 103, so that it generates heat and heats the heat source liquid flowing through the inside thereof. At the same time, the axial flow pump 102 starts to operate, and the heat source liquid is driven to circulate in the system according to the open/close states of the shutoff valve 108 and the shutoff valve 109. The heat source liquid is heated while flowing through the current vortex temperature rising device 103, and then is transferred to the heating surface 101 through a smooth pipe. At the heating surface 101, the heat source liquid emits heat, which causes the radiation surface 105 to rise in temperature and emit infrared radiation. The temperature sensor 106 monitors the temperature of the heat source liquid and the radiation surface 105 in real time and feeds data back to the power unit 107. The power unit 107 intelligently adjusts the power output of the eddy current Wen Shengqi 103 and the axial flow pump 102 according to a preset temperature set point and a feedback signal of the temperature sensor 106 so as to keep the temperature of the radiation surface 105 stable and uniform.
The heating surface 101 is one of the core components of the radiation source device, and is internally provided with a plurality of smooth pipelines. The pipelines are separated by partition boards made of the same materials, so that the heat source liquid can keep a stable flowing state in the heating process. The smooth pipeline is made of materials with excellent heat conduction performance such as red copper and the like so as to improve the heat transfer efficiency. The heat source liquid filled in the smooth pipe can be mineral oil and other substances with good heat stability and fluidity. In addition, in order to prevent impurities in the heat source liquid from damaging the system, a filtering device can be arranged inside the smooth pipeline for filtering treatment.
The performance of the axial flow pump 102 as a driving device for the heat source liquid directly affects the circulation efficiency and stability of the system. Therefore, parameters such as flow, lift, efficiency, etc. of the axial flow pump 102 need to be considered in selecting the axial flow pump to meet the actual demands of the system. The eddy current Wen Shengqi, 103, which is the main provider of the heat source, works on the principle that eddy currents are generated in the conductor by electromagnetic induction and generate heat. The electric vortex temperature-rising device 103 has the advantages of high heating speed, accurate temperature control and the like, and can rapidly convert electric energy into heat energy and heat source liquid.
The finned heat sink 104 is an important heat sink component in the radiation source device, and its design directly affects the heat dissipation effect and stability of the system. The fin radiator 104 employs a variable cross-section design in which the cross-sectional dimensions or spacing of the fins can be adjusted according to the flow rate of the heat source liquid and the heat dissipation requirements. The design mode can furthest improve the heat radiating area and the heat radiating efficiency, and ensures that the system can still keep a stable running state under a high-temperature environment. In addition, a heat radiation fan may be provided on the fin radiator 104 to enhance the heat radiation effect. The rotational speed of the cooling fan can be intelligently adjusted according to the temperature feedback of the fin radiator 104 to achieve more accurate temperature control.
The temperature sensor 106 is one of the key sensing devices in the radiation source apparatus, whose performance directly affects the accuracy and stability of the temperature control. The temperature sensor 106 needs to have characteristics of high accuracy, high stability, and quick response to monitor the temperature of the heat source liquid and the radiation surface 105 in real time. The power unit 107 intelligently adjusts the power output of the eddy current Wen Shengqi and the axial flow pump 102 according to the feedback signal of the temperature sensor 106 so as to realize accurate control of the temperature of the radiation surface 105. The power unit 107 may change the operating states of the eddy current temperature booster 103 and the axial flow pump 102 by adjusting parameters such as a power supply voltage, a current, or a frequency to reach a preset temperature set value.
The radiation source device adopts an efficient and stable heat transfer mechanism, heats heat source liquid through the electric vortex temperature rise device 103 and drives the heat source liquid to circularly flow through the axial flow pump 102 to transfer heat to the radiation surface 105. This design ensures even distribution and rapid transfer of heat in the system, thereby achieving efficient, stable and precise control of the temperature of the radiation surface 105. The device has higher thermal efficiency and faster response speed than conventional electrical heating elements or solid state thermal conduction.
The variable cross-section design of the fin radiator 104 and the intelligent regulation function of the radiator fan enable the radiation source device to be flexibly regulated according to the flow rate of the heat source liquid and the heat dissipation requirement. The design not only improves the heat dissipation efficiency, but also enhances the adaptability and stability of the system. Under the high-temperature environment, the heat dissipation fan can be automatically accelerated to enhance the heat dissipation effect; in a low temperature environment, the rotation speed can be reduced to reduce the energy consumption. In addition, the variable cross-sectional design of the fin radiator 104 also allows the cross-sectional dimensions or spacing of the fins to be adjusted according to actual requirements to further optimize heat dissipation performance.
The cooperation of the temperature sensor 106 and the power unit 107 enables a precise control of the temperature of the radiation surface 105. The temperature sensor 106 is capable of monitoring the temperature of the heat source liquid and the radiation surface 105 in real time and feeding back data to the power unit 107. The power unit 107 intelligently adjusts the power output of the eddy current Wen Shengqi and the axial flow pump 102 according to the preset temperature set value and the feedback signal of the temperature sensor 106, so as to keep the temperature of the radiation surface 105 stable and uniform. This closed loop control mechanism ensures that the temperature of the radiation surface 105 is always kept within a preset range, providing a reliable calibration reference for the infrared measurement device.
The radiation source device fully considers the requirements of environmental protection and energy conservation in the design and use process. The heat source liquid adopts environment-friendly materials such as mineral oil, so that the pollution to the environment is reduced. Meanwhile, through accurate temperature control and an efficient heat dissipation system, the energy consumption and heat loss of the system are reduced. In addition, the device still possesses intelligent regulation function, can adjust power output and radiating effect according to actual demand, has further improved energy utilization efficiency.
The radiation source device can be widely applied to the field of calibration and detection of measurement equipment such as an infrared thermal imager, an infrared thermometer and the like.
