Description

Technical Field

[0001] This utility model belongs to the field of heater technology, specifically relating to a linear focusing heater. Background Technology

[0002] A focusing heater, also known as a focusing lamp, works by reflecting and focusing the light emitted from an infrared heating tube, thereby achieving a heating effect.

[0003] The inventor has been applying for related patents for linear focusing heaters since 2020. In 2021, a linear focusing heater using air cooling was applied for, and in 2023, a linear focusing heater using water cooling was applied for. For specific technical solutions, please refer to the water-cooled linear focusing heater disclosed in Chinese Utility Model Patent No. CN220017285U, which includes a heater body and a light-emitting component. The front end of the heater body is provided with a mounting groove for accommodating the light-emitting component. A cooling device is provided at the rear of the mounting groove. The cooling device passes through the heater body through a water inlet channel and a water outlet channel, and a water circulation structure is provided at the end away from the water supply device.

[0004] While the above-mentioned technical solutions have achieved good technical results, increasing customer demands require adaptation to linear focusing heaters with higher heat generation and better heat dissipation. Therefore, the inventors have improved the existing technology to meet the requirements of more customers. Utility Model Content

[0005] In order to overcome at least some of the shortcomings of the prior art, the present invention provides a linear focusing heater.

[0006] The technical solution provided by this utility model is as follows: A linear focusing heater includes a heating component, a base for mounting the heating component, and a reflector formed by the inward indentation of the lower end of the base. The heating component is installed inside the reflector. Protective shells are provided on both sides of the base. The two ends of the heating component are inserted into the protective shells. The base is machined with a liquid flow channel and an air flow channel. The air flow channel is connected to the protective shell. The protective shell is provided with at least one heat dissipation through hole.

[0007] Furthermore, the fluid flow channel is connected to at least two fluid connectors that connect to external cooling fluid.

[0008] Furthermore, the airflow channel is a bidirectional through-body channel structure, and the protective shell is provided with vent holes corresponding to the airflow channel.

[0009] Furthermore, it also includes a protective component, which includes an L-shaped bent mounting plate and a light-transmitting cover; one end of the mounting plate is fixedly connected to the end face of the base facing the heating component, and the other end is enclosed with the surface of the base to form a receiving cavity; the light-transmitting cover cooperates in the receiving cavity to form a closed heating cavity, and the heating component is located in the heating cavity.

[0010] Furthermore, the heating assembly includes at least one infrared heating lamp and at least one ceramic connector, the ceramic connector being connected to one end of the infrared heating lamp.

[0011] Furthermore, the heating component is connected to the base body via a fixing structure. The fixing structure is provided on the protective shell for fixing the I-shaped groove and adjusting bracket of the ceramic connector. The adjusting bracket is connected to the end of the infrared heating lamp tube away from the ceramic connector.

[0012] Furthermore, the adjustment hole on the adjustment bracket is an oblong hole, and the adjustment bracket is provided with a lamp tube hole. One end of the infrared heating lamp tube passes through the lamp tube hole, and the adjustment bracket is connected to the protective shell by fasteners passing through the adjustment hole.

[0013] The beneficial effects of this invention are as follows: This invention adopts a dual cooling structure of liquid cooling and air cooling, which can be adjusted to three levels. First, the air cooling device removes heat from the base. When the temperature rises further, the liquid cooling device is activated to cool down, while the air cooling device is turned off to control production costs. When the temperature rises even further, both the liquid cooling and air cooling devices are activated simultaneously for the most efficient cooling. This allows for the adaptation to heating components with higher temperatures while also ensuring the lifespan of the heater. Moreover, during production, the corresponding cooling mode can be flexibly matched according to the actual temperature of the focusing heater, avoiding the limitations of a single cooling method. This ensures stable equipment operation while minimizing energy consumption and cost input during the production process. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0016] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0017] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0018] See Figures 1 to 5 This embodiment discloses a linear focusing heater including a heating component 1, a base 2 for mounting the heating component 1, and a reflector 3 formed by the inward recess of the lower end of the base 2. The heating component 1 is installed inside the reflector 3. Protective shells 4 are respectively provided on both sides of the base 2. The two ends of the heating component 1 are respectively inserted into the protective shells 4. The base 2 is machined with a liquid flow channel 21 and an air flow channel 22. The air flow channel 22 communicates with the protective shell 4. The protective shell 4 is provided with at least one heat dissipation through hole 41.

[0019] In some possible embodiments, the base 2 can be made of materials such as stainless steel that can be machined into complex shapes by CNC milling. This allows for the machining of complex shapes required for key structures such as the reflector and the airflow channel 22. Furthermore, the structural strength and stability of the material itself provide reliable guarantees for the installation and positioning of the heating component 1, the energy focusing effect, and the overall heat dissipation efficiency, ensuring the long-term stable operation of the heater.

[0020] In this embodiment, the surface of the reflector is parabolic. Most of the thermal radiation emitted by the heating component will directly irradiate the object to be heated, but some thermal radiation needs to be reflected by the surface of the reflector before it can radiate to the object to be heated. The parabolic shape is the result of optimization. In some possible embodiments, the surface of the reflector can be a smooth curved surface or a complex curved surface after detailed path optimization.

[0021] In practical operation, gradient cooling can be used based on liquid cooling channel 21 and air cooling channel 22 to dissipate heat under different working conditions: When the equipment is started, the external air valve is first opened to allow air to circulate through the air cooling channel 22 and begin cooling, providing basic heat dissipation for the heater under normal operating conditions; when the cooling effect of the air cooling device is insufficient to meet the temperature control requirements after long-term use of the heater, the air valve is closed and the external liquid valve is opened to allow the coolant to flow through the liquid cooling channel 21 for heat dissipation; if liquid cooling alone is still insufficient for effective temperature control, both the air valve and the liquid valve are opened simultaneously to achieve the strongest cooling effect by having both liquid and air cooling work together. The combination of liquid cooling channel 21 and air cooling channel 22 can adapt to the heat dissipation requirements of different working conditions while avoiding unnecessary energy consumption.

[0022] Furthermore, at least two liquid connectors 23 connected to the liquid flow channel 21 are provided for connection with external cooling liquid. In this embodiment, two liquid connectors 23 are used in conjunction with the liquid flow channel 21 to form a complete liquid cooling circulation path. Of course, in actual production, more liquid connectors 23 can be added to increase the coolant flow rate according to the size of the part to be processed or the actual cooling requirements.

[0023] Furthermore, the airflow channel 22 is a bidirectional channel structure that runs through the base 2. The protective shell 4 is provided with a vent 42 corresponding to the airflow channel 22. After the airflow flows out through the airflow channel 22, it is not directly discharged from the equipment. Instead, it first flows through the internal space of the protective shell 4 to cool the end of the heating component 1 located inside the protective shell 4. Then, it is discharged to the outside of the equipment through the heat dissipation hole 41 on the protective shell 4. While cooling the base 2, it can also meet the heat dissipation requirements of the end of the heating component 1.

[0024] Furthermore, it also includes a protective component 5, which comprises an L-shaped bent mounting plate 51 and a light-transmitting cover 52. One end of the mounting plate 51 is fixedly connected to the end face of the base 2 facing the heating component 1, and the other end forms a receiving cavity with the surface of the base 2. The light-transmitting cover 52 cooperates to form a closed heating cavity 53 within the receiving cavity, and the heating component 1 is located within the heating cavity 53. The light-transmitting cover 52 is usually made of transparent quartz glass, mainly used to transmit infrared radiation and prevent smoke from entering and contaminating the reflector 3, thus extending the service life of the reflector 3.

[0025] Furthermore, the heating component 1 includes at least one infrared heating lamp tube 11 and at least one ceramic connector 12. Preferably, in this embodiment, one infrared heating lamp tube and one ceramic connector are used. The lamp tube is an infrared heating lamp tube. Compared with traditional infrared halogen lamp tubes, infrared heating lamp tubes have higher heating efficiency and more concentrated heat radiation. Of course, in some application scenarios where the heating requirements are not high, the infrared heating lamp tube 11 can also be replaced with a traditional halogen lamp tube. The length of the lamp tube is adapted to the length of the base 2 to ensure the coverage of linear heating. The ceramic connector 12 is connected to one end of the infrared heating lamp tube 11. Its ceramic material has excellent insulation and high temperature resistance, which can prevent the equipment from leaking electricity and provide stable support for the infrared heating lamp tube 11.

[0026] Furthermore, the heating component 1 is connected to the base 2 via a fixing structure. The fixing structure includes an I-shaped groove 43 and an adjusting bracket 6 disposed on the protective shell 4 for fixing the ceramic connector 12. The adjusting bracket 6 is connected to the end of the infrared heating lamp 11 away from the ceramic connector 12. The I-shaped groove 43 is directly machined on the surface of the protective shell 4, and its groove structure is adapted to the shape of the ceramic connector 12, which can realize the rapid positioning and fixing of the ceramic connector 12 and effectively prevent the heating component 1 from shifting during operation. The adjusting bracket 6 is used to fine adjust the axial position of the lamp.

[0027] Furthermore, the adjustment hole 61 on the adjustment bracket 6 is an oblong hole. The adjustment bracket 6 is connected to the protective shell 4 by fasteners passing through the adjustment hole 61. The adjustment bracket 6 is provided with the lamp hole 62. One end of the infrared heating lamp 11 passes through the lamp hole 62. The operator can loosen the fasteners to finely adjust the position of the adjustment bracket 6 along the extension direction of the oblong hole, thereby moving the infrared heating lamp 11. The distance between the lamp hole 62 and the protective shell 4 can be adjusted through the oblong hole to accommodate more models of infrared heating lamps 11.

[0028] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
