Description

Technical Field

[0001] This utility model relates to the field of moisture detector technology, specifically a high-temperature resistant near-infrared moisture detector. Background Technology

[0002] In the mining industry, moisture analyzers are crucial devices for real-time monitoring of the moisture content of ores or other materials. These devices typically operate in harsh environments, including high temperatures, high humidity, and dust. While existing moisture analyzers, especially online near-infrared moisture analyzers, offer significant advantages in detection accuracy and response speed, their stability and reliability under high-temperature conditions still face challenges.

[0003] Existing online near-infrared moisture analyzers are prone to damage to their internal electronic components due to overheating when operating in high-temperature environments, leading to decreased detection accuracy or even equipment malfunction. For example, when the ambient temperature reaches 60-70 degrees Celsius, the internal temperature of the device will rise further, exceeding the normal operating temperature range of the electronic components. Current heat dissipation measures mainly include air cooling, but these methods have limited effectiveness in high-temperature environments. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-temperature resistant near-infrared moisture detector. By starting a micro motor, a micro fan blade can be driven to rotate, and the gas containing heat inside the shell is transported to the air duct through the air inlet pipe. After the gas is cooled by heat dissipation fins and water cooling device in the air duct, the low-temperature gas will be blown from the exhaust port of the exhaust pipe to the electrical components on the mounting bracket to cool the electrical components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-temperature resistant near-infrared moisture detector includes a housing. A water-cooling device is provided at the top of the housing, and an air duct is provided at the bottom of the water-cooling device. Heat dissipation fins are provided inside the air duct and are in contact with the water-cooling device. An exhaust pipe and an air inlet pipe are respectively provided at both ends of the air duct and are connected to the air duct. A suction device is provided on the air inlet pipe. A mounting bracket for installing electrical components is provided at the bottom of the housing. An air inlet facing the electrical components is provided at the bottom of the air inlet pipe, and an air outlet facing the electrical components is provided at the bottom of the exhaust pipe.

[0006] Preferably, the water-cooling device has a water-cooling cavity located at the top of the housing. The water-cooling cavity has an inlet pipe and an outlet pipe at its two ends, respectively. A water chiller is located at the top of the housing, and the inlet pipe and outlet pipe are both connected to the water chiller.

[0007] Preferably, the suction device includes multiple frames, the frames are located at the air inlet, a micro motor is mounted on the frame, and a micro fan blade is mounted on the power output end of the micro motor.

[0008] Preferably, both the heat dissipation fins and the water cooling cavity are made of aluminum.

[0009] Preferably, the housing contains a storage battery, which is electrically connected to a micro motor.

[0010] Preferably, the front side of the housing is provided with a front door panel, and the rear side of the housing is provided with a rear door panel.

[0011] Preferably, the interior of the housing, as well as the inner sides of the front and rear door panels, are provided with heat insulation cotton.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a simple structure. By activating the suction device, the heat generated by the electrical components is transported to the air duct through the air inlet pipe. Since the air duct is equipped with multiple heat dissipation fins, and the heat from the contact between the heat dissipation fins and the water cooling device is conducted to the water cooling device for heat dissipation, the heat transported to the air duct will continuously decrease due to the continuous cooling of the water cooling device. As the suction device continues to work, it will continuously bring in hot gas into the air duct. After the gas is cooled by the heat dissipation fins and the water cooling device in the air duct, the low-temperature gas will be blown from the exhaust port of the exhaust pipe to the electrical components on the mounting bracket to cool the electrical components. Through the combination of water cooling and air cooling, the airflow inside the shell is driven to flow, continuously carrying away the heat generated by the electrical components and cooling the electrical components through the low-temperature airflow, ensuring the normal operation of the moisture detector and ensuring the service life of the moisture monitor.

[0013] 2. This device transfers heat from the interior of the casing to the heat dissipation fins via thermal convection. The fins then transfer the heat to the water-cooling cavity via thermal conduction. Since both the heat dissipation fins and the water-cooling cavity are made of aluminum, aluminum's high thermal conductivity ensures efficient heat transfer from the fins to the water-cooling cavity. The water inside the water-cooling cavity is connected to an external water chiller via pipes. The water chiller cools the water inside the cavity through its refrigeration system, thereby removing heat and maintaining a low temperature inside the water-cooling cavity.

[0014] 3. In addition to the battery, the housing of this device also contains a microcontroller, which receives sensor signals and controls the operation of the micro motor according to preset logic, as well as a power management module, which can not only manage the charging and discharging of the battery to ensure that the battery works within a safe voltage range, but also provide a stable power supply voltage for the micro motor to avoid the impact of voltage fluctuations on the micro motor. A control switch is located on the outside of the housing to control the microcontroller.

[0015] 4. This device features front and rear door panels on the front and rear sides of the housing, respectively. These panels provide quick access to the interior of the housing, facilitating regular inspections, cleaning, component replacement, and troubleshooting by maintenance personnel. This design reduces maintenance time and workload, improving the availability and reliability of the equipment. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 A high-temperature resistant near-infrared moisture detector, with the following structure: Figures 1-5 As shown, the device includes a housing 1. A water-cooling device is provided at the top of the housing 1. An air duct 9 is provided at the bottom of the water-cooling device. Heat dissipation fins 8 are provided inside the air duct 9 and are in contact with the water-cooling device. An exhaust pipe 10 and an air inlet pipe 11, which are connected to the air duct 9, are respectively provided at both ends of the air duct 9. A suction device is provided on the air inlet pipe 11. A mounting bracket 15 for installing electrical components is provided at the bottom of the housing 1. An air inlet 17 facing the electrical components is provided at the bottom of the air inlet pipe 11, and an exhaust outlet 16 facing the electrical components is provided at the bottom of the exhaust pipe 10.

[0020] When the moisture detector is in use, the electrical components inside the housing 1 are prone to overheating due to the high ambient temperature. By activating the suction device, the heat generated by the electrical components is transported to the air duct 9 through the air inlet pipe 11. Since the air duct 9 is equipped with multiple heat dissipation fins 8, and the heat from the contact between the heat dissipation fins 8 and the water cooling device is conducted to the water cooling device for heat dissipation, the heat transported to the air duct 9 will continuously decrease due to the continuous cooling of the water cooling device. As the suction device continues to work, it will continuously bring in hot gas into the air duct 9. After the gas is cooled by the heat dissipation fins 8 and the water cooling device in the air duct 9, the low-temperature gas will be blown from the exhaust port 16 of the exhaust pipe 10 to the electrical components on the mounting bracket 15 to cool the electrical components. Through the combination of water cooling and air cooling, the airflow inside the housing 1 is driven to flow, continuously carrying away the heat generated by the electrical components and cooling the electrical components through the low-temperature airflow, ensuring the normal operation of the moisture detector and ensuring the service life of the moisture detector.

[0021] The water cooling device has a water cooling chamber 7 located at the top of the housing 1. The water cooling chamber 7 has an inlet pipe 5 and an outlet pipe 6 at its two ends. The housing 1 has a water chiller 4 at the top. The inlet pipe 5 and the outlet pipe 6 are both connected to the water chiller 4.

[0022] When the water chiller 4 is working, water from inside the water cooling chamber 7 is drawn into the water chiller 4 through the water inlet pipe 5. After being cooled by the water chiller 4, the low-temperature water enters the water cooling chamber 7 through the water outlet pipe 6, ensuring that the water temperature inside the water cooling chamber 7 is at a low temperature. This facilitates the heat dissipation fins 8 to transfer the heat in the airflow to the water cooling chamber 7, thereby achieving the effect of cooling the airflow inside the casing 1 and ensuring the normal operation of the moisture detector.

[0023] The suction device includes multiple frames 13, which are located at the air inlet 17. A micro motor 14 is mounted on the frame 13, and a micro fan blade 12 is mounted on the power output end of the micro motor 14.

[0024] Multiple micro motors 14 are installed at the air inlet 17 of the air inlet duct 11 through corresponding frames 13. The micro motors 14 drive the micro fan blades 12 to rotate, which transport the gas inside the housing 1 to the air duct 9 through the air inlet duct 11, so as to effectively cool the high temperature gas. At the same time, the cooled low temperature gas can be blown to the electrical components on the mounting bracket 15 through the exhaust port 16 of the exhaust duct 10, so as to effectively cool the electrical components.

[0025] Both the heat dissipation fins 8 and the water cooling cavity 7 are made of aluminum.

[0026] When hot air flows through the heat dissipation fins 8, heat is transferred to the fins 8 via thermal convection. The heat dissipation fins 8 then transfer the heat to the water-cooling cavity 7 via thermal conduction. Since both the heat dissipation fins 8 and the water-cooling cavity 7 are made of aluminum, the high thermal conductivity of aluminum ensures that heat can be efficiently transferred from the heat dissipation fins 8 to the water-cooling cavity 7. The water inside the water-cooling cavity 7 is connected to the external water chiller 4 through pipes. The water chiller 4 cools the water inside the water-cooling cavity 7 through its refrigeration system, thereby removing heat and maintaining a low temperature inside the water-cooling cavity 7.

[0027] The housing 1 contains a storage battery, which is electrically connected to the micro motor 14.

[0028] The housing 1 also houses a microcontroller for receiving sensor signals and controlling the operation of the micro motor 14 according to preset logic, as well as a power management module, which can not only manage the charging and discharging of the battery to ensure that the battery works within a safe voltage range, but also provide a stable power supply voltage for the micro motor 14 to avoid voltage fluctuations affecting the micro motor 14. The housing 1 is equipped with a control switch for controlling the microcontroller.

[0029] Example 2 Based on Embodiment 1, the front side of the housing 1 is provided with a front door panel 2, and the rear side of the housing 1 is provided with a rear door panel 3.

[0030] By providing a front door panel 2 and a rear door panel 3 on the front and rear sides of the housing 1 respectively, the front door panel 2 and the rear door panel 3 can provide a quick way to open the interior of the housing 1, facilitating maintenance personnel to perform regular inspections, cleaning, component replacement, or troubleshooting. This design reduces maintenance time and workload, and improves the availability and reliability of the equipment.

[0031] The interior of the housing 1, as well as the inner sides of the front door panel 2 and the rear door panel 3, are all provided with heat insulation cotton.

[0032] Thermal insulation effectively reduces heat transfer, maintaining a relatively stable internal temperature for the housing 1. This is particularly important for moisture detectors that operate in high-temperature environments, preventing external heat from affecting internal components. By installing thermal insulation on the interior of the housing 1 and the inner walls of the front and rear panels 2 and 3, the thermal stability of the equipment is significantly improved, internal components are protected, energy efficiency is enhanced, and safety and protective performance are strengthened. This design not only reduces the impact of the external environment on the equipment but also optimizes its operating efficiency and extends its service life. A mounting bracket with through holes is located on the top of the housing, allowing for easy installation of the device at the desired moisture detection location using screws and nuts.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
