Description

Technical Field

[0001] The invention relates to the field of infrared heating, and in particular to a high-efficiency water-cooled and air-cooled integrated infrared focusing device. Background Art

[0002] Existing infrared focusing devices face many challenges in actual use. On the one hand, when the device is running, since the infrared source continues to generate heat, the traditional single cooling method is difficult to effectively dissipate the heat, which easily leads to overheating of the device. The overheating problem not only affects the performance stability of the device, greatly reducing the accuracy and effect of infrared focusing, but also may shorten the service life of key components inside the device, increase the maintenance cost and replacement frequency of the equipment, and thus affect the reliability and operation efficiency of the entire system. When starting in a low-temperature environment, the infrared source needs to reach a specific operating temperature to have enough energy for precise focusing. However, traditional infrared focusing devices often have the defect of slow preheating speed during low-temperature startup. This not only prolongs the waiting time for the equipment to enter the normal working state and reduces the working efficiency, but also consumes a lot of energy during the preheating process. At the same time, due to the slow heating process during low-temperature startup, the infrared source is also at risk of being damaged due to uneven temperature changes, further reducing the reliability and service life of the device.

[0003] In response to these problems, the prior art has proposed some improvement plans, but there are still certain limitations. For example, the patent with publication number CN114501700A discloses an explosion-proof infrared heating device with low energy consumption, which still has the following deficiencies in the field of infrared heating: 1. The device can monitor the internal temperature in real time and use a fan to dissipate heat. This heat dissipation method has high requirements for the ambient temperature. When the ambient temperature is high, the heat dissipation may be lower than the heat generation, which reduces the heating efficiency of the infrared heating mechanism and also reduces the service life of the equipment. 2. For cold areas, the low-temperature startup of the equipment has a greater impact on the life of the infrared source, and the efficiency of the infrared source in generating heat is not high enough under low temperature conditions, requiring a long time of preheating. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the present invention aims to provide a highly efficient water-cooled and air-cooled integrated infrared focusing device, which solves the problems existing in the prior art. By combining water cooling with air cooling, an air cooling mechanism is fixed on the upper end of the water-cooled infrared source, and the infrared source body is cooled by water cooling. The air cooling mechanism assists in further heat dissipation, effectively preventing the device from overheating during operation, ensuring the stability of the device performance and the normal service life of each component. In addition, the water-cooled and air-cooled integrated structure can ensure that the device can quickly reach the operating temperature when started in a low-temperature environment, reducing energy consumption during preheating, not only improving the efficiency of the device entering the working state, but also being more energy-saving and environmentally friendly, while also reducing the risk of damage to the infrared source due to uneven temperature changes during low-temperature startup, and extending the overall service life of the device.

[0006] (II) Technical solution

[0007] To achieve the above purpose, the present invention provides the following technical solutions: an efficient water-cooled and air-cooled integrated infrared focusing device, comprising a water-cooled infrared source, an air-cooling mechanism fixed on the upper end of the water-cooled infrared source, and a shell fixed on the outer side of the air-cooling mechanism; the water-cooled infrared source is the core structure of the device, which provides infrared light by an incandescent lamp, and gathers the infrared light through a lampshade to heat the object. Compared with other light sources, the incandescent lamp has the advantages of mature technology, good luminous stability, low cost, etc., and under normal working conditions, the infrared radiation intensity output by it is relatively stable, and there will be no obvious flicker or fluctuation. On the one hand, the air-cooling mechanism can work in coordination with the water-cooling system in the water-cooled infrared source, quickly take away the heat generated inside the device, avoid heat accumulation, effectively reduce the temperature of the device, and ensure that the device is maintained in a suitable temperature range while operating efficiently; on the other hand, it enhances the air flow inside the device, improves the heat dissipation efficiency, and ensures the performance stability and service life of each component of the device. The shell protects the internal components from external physical impacts and cooperates with the air-cooling mechanism, making the air flow in the air-cooling mechanism more reasonable, and improving the heat dissipation efficiency of the air-cooling mechanism.

[0008] The air cooling mechanism includes a cover plate fixed on the upper end of the water-cooled infrared source, a lamp holder is fixed on the upper end of the cover plate, an air inlet is fixed on the upper end of the lamp holder, a copper column is fixed on the circumference of the upper end of the lamp holder, and a heat dissipation fan is fixed on the upper end of the copper column; the cover plate is fixed on the upper end of the water-cooled infrared source, and plays the role of connecting the water-cooled infrared source and other components of the air cooling mechanism, and together with the water-cooling shell and the lampshade, it forms a closed space to prevent the water in the water-cooled infrared source from flowing out and affecting the operation of the device. The lamp holder is used to fix the incandescent lamp and dissipate heat, and the heat dissipation area is increased by the heat dissipation fins to quickly dissipate heat into the air. The air flows inside and around the lamp holder through the through holes and the air inlet, enhancing the heat dissipation effect and ensuring that the components on the lamp holder work in a suitable temperature environment. The air inlet is the main entrance of the cold air of the air cooling system, connecting the external air to enter the lampshade, taking away the heat emitted by the incandescent lamp, ensuring that the incandescent lamp will not overheat when working, and greatly extending the service life of the incandescent lamp. The copper column connects the lamp holder and the heat dissipation fan, provides physical support for the heat dissipation fan, and uses the good thermal conductivity of copper to conduct heat. While ensuring the stable installation of the cooling fan, the heat on the lamp holder can be dissipated into the air and blown out of the device by the cooling fan, which improves the heat dissipation performance of the entire device. The cooling fan drives the blades to rotate through the motor to generate forced airflow.

DETAILED DESCRIPTION

[0031] The following will be combined with the attached examples of the present invention Figure 1 -Attached Fig.11 The technical solution in this embodiment is described clearly and completely. Obviously, the described embodiment is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, the present invention provides a technical solution: a high-efficiency water-cooled and air-cooled integrated infrared focusing device, comprising a water-cooled infrared source 1, an air-cooling mechanism 2 is fixed on the upper end of the water-cooled infrared source 1, and a shell 3 is fixed on the outer side of the air-cooling mechanism 2; the water-cooled infrared source 1 is the core structure of the device, which is provided with infrared light by an incandescent lamp 101, and the infrared light is gathered through a lampshade 105 to heat the object, and the incandescent lamp 101 has the advantages of mature technology, good luminous stability, low cost, etc. compared with other light sources, and under normal working conditions, the infrared radiation intensity outputted by it is relatively stable, and no obvious flicker or fluctuation will occur. On the one hand, the air-cooling mechanism 2 can work in coordination with the water-cooling system in the water-cooled infrared source 1, quickly take away the heat generated inside the device, avoid heat accumulation, effectively reduce the temperature of the device, and ensure that the device is maintained in a suitable temperature range while operating efficiently; on the other hand, it enhances the air flow inside the device, improves the heat dissipation efficiency, and ensures the performance stability and service life of each component of the device. The housing 3 protects the internal components from external physical impacts and cooperates with the air cooling mechanism 2 to make the air flow in the air cooling mechanism 2 more reasonable, thereby enhancing the heat dissipation efficiency of the air cooling mechanism 2.

[0033] like Figure 2As shown, the air cooling mechanism 2 includes a cover plate 201 fixed to the upper end of the water-cooled infrared source 1, a lamp holder 202 is fixed to the upper end of the cover plate 201, an air inlet 203 is fixed to the upper end of the lamp holder 202, a copper column 204 is fixed to the upper end of the lamp holder 202, and a heat dissipation fan 205 is fixed to the upper end of the copper column 204; the cover plate 201 is fixed to the upper end of the water-cooled infrared source 1, and plays the role of connecting the water-cooled infrared source 1 and other components of the air cooling mechanism 2, and together with the water-cooling shell 102 and the lampshade 105, it forms a closed space to prevent the water in the water-cooled infrared source 1 from flowing out and affecting the operation of the device. The lamp holder 202 is used to fix the incandescent lamp 101 and dissipate heat, and the heat dissipation area is increased by the heat dissipation fins 2021 to quickly dissipate heat into the air. The air flows inside and around the lamp holder 202 through the through holes and the air inlet holes, enhancing the heat dissipation effect and ensuring that the components on the lamp holder 202 work in a suitable temperature environment. The air inlet 203 is the main entrance of the cold air of the air cooling system. It connects the external air to enter the lampshade 105, takes away the heat emitted by the incandescent lamp 101, ensures that the incandescent lamp 101 will not overheat when working, and greatly prolongs the service life of the incandescent lamp 101. The copper column 204 connects the lamp holder 202 and the heat dissipation fan 205, provides physical support for the heat dissipation fan 205, and conducts heat by using the good thermal conductivity of copper. While ensuring the stable installation of the heat dissipation fan 205, the heat on the lamp holder 202 can be dissipated into the air, and blown out of the device by the heat dissipation fan 205, thereby improving the heat dissipation performance of the entire device. The heat dissipation fan 205 drives the blades to rotate through the motor to generate forced airflow. Blowing through the copper column 204 and the lamp holder 202, the air flow speed inside the device is enhanced, and the air cooling efficiency is greatly improved. It can quickly take away the heat generated inside the device, prevent heat accumulation, and ensure that the device maintains a low temperature while operating efficiently.

[0034] like Figure 3As shown, the water-cooled infrared source 1 includes an incandescent lamp 101 fixed on a lamp holder 202, a lampshade 105 is arranged outside the incandescent lamp 101, a water-cooled shell 102 is fixed outside the lampshade 105, a glass cover plate 106 is installed at the lower part of the water-cooled shell 102, a water inlet 104 is fixed on the side of the water-cooled shell 102, and a water outlet 103 is fixed above the water inlet 104; the incandescent lamp 101 is the core heating component of the device, and generates heat through the current passing through the filament, thereby emitting infrared light. It is the source of infrared radiation of the entire device and provides an energy basis for infrared focusing. The water-cooled shell 102, the lampshade 105 and the cover plate 201 form a closed water-cooled space. The circulation of cooling water is realized through the water inlet 104 and the water outlet 103. The heat generated by the incandescent lamp 101 is effectively absorbed to prevent the device from being damaged due to overheating. Through water cooling, the heat can be quickly taken away, the internal temperature of the device is maintained stable, and the long-term stable operation of the device is guaranteed. The water outlet 103 is at the top and the water inlet 104 is at the bottom, which can ensure the high efficiency of water cooling and heat dissipation to the greatest extent. When the water is heated, water vapor will be formed in the water-cooled shell 102. After the water vapor accumulates, the water in the water-cooled shell 102 will become less. The water outlet 103 is at the top, which can discharge the water vapor in time. At the same time, water enters from the bottom, and the water rises after being heated, ensuring that the discharged water fully absorbs the heat of the incandescent lamp 101 before being discharged. The lampshade 105 firstly protects the incandescent lamp 101 from external physical damage and interference from impurities such as dust; secondly, it gathers and guides the infrared light to a certain extent. The various hole structures inside it provide channels for air circulation. The glass cover 106 is used to protect the incandescent lamp 101 inside, and can filter the light generated by the incandescent lamp 101, so as to transmit the infrared light to the greatest extent and ensure the high efficiency of heating.

[0035] like Figure 4 As shown, the lamp holder 202 is evenly provided with heat dissipation fins 2021 on the circumference, a fixing hole 2022 is provided at the center of the lamp holder 202, a first through hole 2023 is provided on the side of the fixing hole 2022, a second through hole 2024 is provided on the side of the first through hole 2023, and a first air inlet 2025 is symmetrically provided on the second through hole 2024; heat dissipation fins 2021 The heat dissipation fins 2021 are designed on the circumference of the lamp holder 202, and their shape is generally thin and has a plurality of fin structures. This design can greatly increase the surface area of ​​the lamp holder 202 in contact with the air. The fixing hole 2022 is used to fix the incandescent lamp 101, the first through hole 2023 and the second through hole 2024 are used to place the temperature sensor, and the first air inlet 2025 is used to receive the air entering from the air inlet 203.

[0036] like Figure 5As shown, a fixing platform 2011 is arranged at the center of the cover 201, a third through hole 2012 is arranged on the side of the fixing platform, a fourth through hole 2013 is arranged on the side of the third through hole, and a second air inlet hole 2014 is symmetrically arranged on the fourth through hole 2013; after the incandescent lamp 101 passes through the fixing hole 2022, it is placed on the fixing platform 2011 to fix its position, the third through hole 2012 and the fourth through hole 2013 are both used to pass the temperature sensor, and the second air inlet hole 2014 is used to pass the air entering from the air inlet 203.

[0037] like Figure 6 As shown, a lamp hole 1051 is arranged at the center of the lampshade 105, a countersunk hole 1052 is arranged on the side of the lamp hole 1051, a fifth through hole 1053 is arranged on the side of the countersunk hole 1052, and a third air inlet hole 1054 is symmetrically arranged on the fifth through hole 1053; the incandescent lamp 101 penetrates into the lampshade 105 from the lamp hole 1051, the countersunk hole 1052 and the fifth through hole 1053 are both used to place temperature sensors, and the air entering from the air inlet 203 finally enters the interior of the lampshade 105 through the third air inlet hole 1054.

[0038] like Figure 7 As shown, the fifth through hole 1053 and the third air inlet hole 1054 connect the upper end and the interior of the lampshade 105; the setting of the fifth through hole 1053 can ensure that the temperature sensor extends into the lampshade 105, thereby measuring the temperature of the air inside the lampshade, adjusting the volume of air entering the air inlet 105, and ensuring that the incandescent lamp 101 is at a suitable operating temperature.

[0039] like Figure 8 As shown, the countersunk hole 1052 penetrates into the upper 1 / 2 position of the lampshade; the setting of the countersunk hole 1052 can ensure that the temperature sensor is located inside the lampshade 105, accurately measure the temperature inside the lampshade 105, adjust the size of the water flow, and ensure that the lampshade 105 will not be deformed due to high temperature.

[0040] like Fig. 9 and 10 As shown, the fixing hole 2022 is a stepped hole, the upper half is a waist-shaped hole 20221, and the lower half is a special-shaped hole 20222. The two sides of the special-shaped hole 20222 form steps with the waist-shaped hole 20221; after the incandescent lamp 101 is placed on the fixing platform 2011 of the cover plate 201, the special-shaped hole 20222 limits the planar movement of the incandescent lamp 101, and the waist-shaped hole 20221 limits the vertical movement of the incandescent lamp 101, so that the installation of the incandescent lamp 101 is more stable.

[0041] like Figure 7 As shown, the first air inlet 2025, the second air inlet 2014 and the third air inlet 1054 form an intake flow passage, as shown in FIG. Figure 8The fixing hole 2022, the fixing platform 2011 and the lamp hole 1051 form an air outlet passage, and air flows out from the gap outside the incandescent lamp 101. Figure 3 The water inlet 104 and the water outlet 103 shown form a water channel. The three channels cooperate with each other to achieve the following effects:

[0042] 1. Heat dissipation during operation: When the device is in operation, the water channel is responsible for taking out the heat from the lampshade 105. After the air flows into the lampshade 105 from the inlet channel, it will flow downward along the inner wall of the lampshade 105 due to the effect of viscosity, fully absorbing the heat in the lampshade 105. After absorbing the heat in the lampshade 105, the air gathers at the bottom of the lampshade 105 and then flows over the surface of the incandescent lamp 101. Due to the special design of the special-shaped hole 20222 and the outlet channel (formed by the fixing hole 2022, the fixing platform 2011 and the lamp hole 1051), the air can fully take away the heat on the surface of the incandescent lamp 101 when passing through the surface. The special-shaped hole 20222 is not only used to fix the incandescent lamp 101, but also provides an area with a larger diameter for the outlet channel. When the air passes through this area, the flow rate is reduced, so that the heat can be more fully transferred to the lamp holder 202. The lamp holder 202 is evenly provided with heat dissipation fins 2021 on the circumference thereof. The heat dissipation fins 2021 are in the shape of thin sheets and have a plurality of fin structures, which greatly increases the surface area of ​​the lamp holder 202 in contact with the air. After the heat is transferred to the lamp holder 202, it is dissipated through the heat dissipation fins 2021 and finally blown out of the device by the heat dissipation fan 205, which greatly improves the air cooling efficiency, prevents heat accumulation, and ensures that the device maintains a low temperature while operating efficiently.

[0043] 2. Heating effect during low-temperature startup: Heat absorption and transfer of the inlet air duct: During low-temperature startup, air enters from the air inlet 203 and enters the device through the inlet air duct (the first air inlet 2025, the second air inlet 2014 and the third air inlet 1054). After entering, the air passes through the inner wall of the lampshade 105. At this time, the water flow temperature outside the lampshade 105 is higher than 0°C, because the water circulates in the water-cooled shell 102 and can maintain a certain temperature even in a low-temperature environment. The air absorbs its heat when passing through the inner wall of the lampshade 105. Heating of the incandescent lamp by the outlet air duct: The air that has absorbed the heat continues to flow through the incandescent lamp 101. At the same time, the larger diameter area (formed by the special-shaped hole 20222) on the outlet air duct (formed by the fixing hole 2022, the fixing platform 2011 and the lamp hole 1051) can reduce the air flow rate, so that the incandescent lamp 101 can fully absorb the heat in the air. In this way, the incandescent lamp 101 can quickly reach the operating temperature when it is started at a low temperature, so that it can emit infrared light normally, providing an energy basis for the normal operation of the entire device. The coordination between these channels ensures that the device can work stably and efficiently under different working conditions (operation heat dissipation and low temperature start heating).

[0044] like Fig.11As shown, an air inlet 301 is arranged on the circumference of the lower end of the side of the housing 3, and an air outlet 302 is evenly arranged on the upper end surface of the housing 3. A square flange socket 303 is arranged at the center of the upper end surface of the housing 3; air flows from the air inlet 301 to the air outlet 302 and flows through the heat dissipation fins 2021, so that the device can fully dissipate heat. The square flange socket 303 is used to connect the external power supply and the internal electrical appliances.

[0045] How it works

[0046] In terms of water cooling and heat dissipation: the water-cooling shell 102 of the water-cooled infrared source 1, the lampshade 105, and the cover plate 201 form a closed water cooling space, and the cooling water circulates through the water inlet 104 and the water outlet 103, which can effectively absorb the heat generated by the incandescent lamp 101. The design of the water outlet 103 at the top and the water inlet 104 at the bottom can ensure the high efficiency of water cooling and heat dissipation, maintain the internal temperature of the device stable, and prevent overheating damage.

[0047] Air cooling:

[0048] The cover plate 201 of the air cooling mechanism 2 connects the water-cooled infrared source 1 and other components to form a closed space to prevent water leakage; the lamp holder 202 is used to fix the incandescent lamp 101 and increase the heat dissipation area through the heat dissipation fins 2021, and the air inlet 203 introduces external cold air into the lampshade 105 to take away heat. The copper column 204 connects the lamp holder 202 and the heat dissipation fan 205 to conduct heat and provide support. The heat dissipation fan 205 generates forced airflow to enhance the air flow speed and improve the heat dissipation efficiency.

[0049] Air flow and heat dissipation process: the first air inlet 2025, the second air inlet 2014 and the third air inlet 1054 form an inlet air duct, so that after the external cold air enters the lampshade 105, it flows downward along the inner wall to absorb heat, and then flows through the surface of the incandescent lamp 101 to take away the heat, and flows out through the outlet air duct formed by the fixing hole 2022, the fixing platform 2011 and the lamp hole 1051. The air flow rate at the special-shaped hole 20222 in the outlet air duct is reduced, and the heat is fully transferred to the lamp holder 202. After the heat is dissipated by the heat dissipation fins 2021, it is blown out of the device by the heat dissipation fan 205.

[0050] Heating principle at low temperature start-up

[0051] When starting at low temperature, air enters from the inlet flow channel, passes through the inner wall of the lampshade 105 to absorb the heat of the external circulating water flow (because the water flow temperature is higher than 0°C), and then flows through the incandescent lamp 101. At the same time, the larger diameter area on the outlet flow channel allows the incandescent lamp 101 to fully absorb the heat in the air, so that the incandescent lamp 101 quickly reaches the operating temperature and ensures the normal operation of the device.
