Description

Technical Field

[0001] This utility model relates to the field of PTC heater technology, and in particular to a low-power superconducting PTC heater assembly. Background Technology

[0002] A PTC heater, also known as a PTC heating element, is a heating element composed of a PTC ceramic heating element and an aluminum tube. The PTC heater utilizes the constant-temperature heating characteristic of the PTC thermistor. After the PTC thermistor is energized, it heats up and its resistance enters the transition region, and its surface temperature will remain constant. This temperature is only related to the Curie temperature of the PTC thermistor and the applied voltage. The PTC ceramic heating element is usually composed of a galvanized outer pressure plate, a stainless steel corrugated spring sheet, a galvanized inner pressure plate, a single-layer aluminum heat sink, a PTC heating element, a double-layer aluminum heat sink, nickel-plated copper electrode terminals, and a PPS high-temperature plastic electrode sheath.

[0003] Traditional devices are difficult to dynamically match heating needs, resulting in energy waste. Fixed spacing cannot adjust the layout of the heaters according to the size, shape or heat demand of the heating target. When heating small objects, too large a spacing causes heat to disperse, requiring a longer heating time and increasing standby power consumption. When heating large objects, too small a spacing causes local overheating while the edge area is not hot enough, forcing a longer overall heating time and increasing energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a low-power superconducting PTC heater assembly that can solve the problems of traditional devices having difficulty dynamically matching heating needs, resulting in energy waste, fixed spacing that cannot adjust the heater layout according to the size, shape or heat demand of the heating target, excessive spacing when heating small objects causing heat dispersion, requiring longer heating time and increasing standby power consumption, and insufficient spacing when heating large objects causing local overheating while the edge area is not hot enough, forcing a longer overall heating time and increasing energy consumption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-power superconducting PTC heater assembly, including a heater body and a connecting mechanism disposed on the outer side of the end of the heater body, the connecting mechanism being used to flexibly and quickly adjust the distance between the two heater bodies.

[0006] In a preferred embodiment, the connecting mechanism includes a connecting block, which is fixedly connected to the outer side of one end of the heater body. A plug rod is slidably connected to the inner side of one end of the connecting block. A connecting rod is fixedly connected to the outer side of one end of the plug rod. A limiting ball is fixedly connected to the outer side of the end of the connecting rod. Locking blocks are slidably connected to the inner sides of both ends of the connecting block. The outer side of the limiting ball contacts one side of the locking block. A limiting plate is slidably connected to the outer side of the connecting block.

[0007] In a preferred embodiment, a spring is fixedly connected to the outer side of one end of the connecting rod, and the outer side of one end of the spring is fixedly connected to the inner side of one end of the connecting block.

[0008] In a preferred embodiment, a first handle is fixedly connected to the outer side of one end of the insertion rod, and a second handle is fixedly connected to one side of the connecting block.

[0009] In a preferred embodiment, an anti-slip strip is fixedly connected to the outer side of one end of the card block, and the anti-slip strip is made of rubber.

[0010] In a preferred embodiment, a slider is fixedly connected to the outer side of one end of the heater body, and a slide rail is slidably connected to the outer side of the slider.

[0011] In a preferred embodiment, connecting plates are fixedly connected to the outer sides of both ends of the slide rail, and cooling fans are installed on the inner sides of both ends of the connecting plates.

[0012] In a preferred embodiment, a handle is fixedly connected to one side of the connecting plate.

[0013] Compared with existing technologies, the advantages and positive effects of this utility model are as follows: In use, the spacing of the connecting mechanism can be dynamically adjusted according to actual heating needs, ensuring uniform heat distribution and avoiding power waste caused by localized overheating. When heating large-area objects, increasing the spacing between the heating element bodies expands the heat coverage area and reduces energy consumption from repeatedly heating the same area. Increasing the spacing also reduces internal heat conduction losses, allowing more heat to act on the target object. Conversely, reducing the spacing between the heating element bodies utilizes the synergistic effect between them to rapidly raise the temperature, shortening preheating time and avoiding prolonged, inefficient heating. Furthermore, some superconducting materials possess highly efficient thermal conductivity; adjusting the spacing between the heating element bodies can optimize the thermal superconducting path and reduce energy attenuation during heat transfer.

[0021] 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.

[0022] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a low-power superconducting PTC heater assembly, including a heater body 1 and a connecting mechanism 2 disposed on the outer side of the end of the heater body 1. The connecting mechanism 2 is used to flexibly and quickly adjust the distance between the two heater bodies 1. The connecting mechanism 2 includes a connecting block 21, which is fixedly connected to the outer side of one end of the heater body 1. A plug rod 22 is slidably connected to the inner side of one end of the connecting block 21. A connecting rod 23 is fixedly connected to the outer side of one end of the plug rod 22. A limit switch is fixedly connected to the outer side of the end of the connecting rod 23. Ball 24 and connecting block 21 are slidably connected to the inner sides of both ends of the ball 24 and the connecting block 21. The outer side of the ball 24 is in contact with one side of the connecting block 25. The outer side of the connecting block 21 is slidably connected to the limiting plate 215. One end of the connecting rod 23 is fixedly connected to the outer side of one end of the connecting block 21. One end of the spring 26 is fixedly connected to the outer side of one end of the connecting block 21. One end of the insert rod 22 is fixedly connected to the outer side of one end of the first handle 27. One side of the connecting block 21 is fixedly connected to the second handle 28. One end of the connecting block 25 is fixedly connected to the outer side of the anti-slip strip 29. The anti-slip strip 29 is made of rubber.

[0023] When adjusting the distance between the two heater bodies 1 using this device, the user can simultaneously grip the first handle 27 and the second handle 28. Since the second handle 28 is fixedly connected to one side of the connecting block 21, it will cause the connecting rod 23 and the limiting ball 24 on one side of the insertion rod 22 to slide inwards towards the connecting block 21, simultaneously compressing the spring 26. At this point, the outer side of the limiting ball 24 disengages from the two locking blocks 25, and the limiting ball 24 loses its support for the two locking blocks 25. The user can then slide the connecting block 21, thereby causing the two heater bodies 1 to slide, adjusting the distance between them. After the position adjustment is complete, the user releases the grip on the first handle 27 and the second handle 28. The elastic potential energy of the spring 26 is released, pushing the connecting rod 23 outwards, and the limiting ball 24 again presses against the two locking blocks. On the outside of block 25, the anti-slip strip 29 on one side of block 25 applies pressure to the inner wall of the trapezoidal groove on one end of the limiting plate 215, limiting the connecting block 21. The spacing can be dynamically adjusted according to the actual heating requirements through the connecting mechanism 2, so that the heat is evenly distributed and the power waste caused by local overheating is avoided. When heating a large area of ​​objects, increasing the spacing of the heating body 1 can expand the heat coverage area and reduce the energy consumption of repeatedly heating the same area. By increasing the spacing, the internal heat conduction loss can be reduced, so that more heat can be applied to the target object. By reducing the spacing of the heating body 1, the synergistic effect between the heating body 1 can be used to quickly heat up, shorten the preheating time, and avoid long-term low-efficiency heating. Some superconducting materials also have high-efficiency thermal conductivity. The thermal superconducting path can be optimized by adjusting the spacing of the heating body 1 to reduce the energy attenuation during the heat transfer process.

[0024] like Figure 1 - Figure 4 As shown, a slider 211 is fixedly connected to the outer side of one end of the heater body 1, a slide rail 210 is slidably connected to the outer side of the slider 211, a connecting plate 212 is fixedly connected to the outer sides of both ends of the slide rail 210, a cooling fan 213 is installed on the inner side of both ends of the connecting plate 212, and a handle 214 is fixedly connected to one side of the connecting plate 212.

[0025] Meanwhile, the stability of the movement of the two heating element bodies 1 can be increased by the slider 211 and the slide rail 210, and the cooling fan 213 can be activated to dissipate heat from the heating element bodies 1. The device can be easily moved by the two handles 214.

[0026] Working principle: When adjusting the distance between the two heater bodies 1, the user can simultaneously grip the first handle 27 and the second handle 28. Since the second handle 28 is fixedly connected to one side of the connecting block 21, it will cause the connecting rod 23 and the limiting ball 24 on one side of the insertion rod 22 to slide inwards towards the connecting block 21, simultaneously compressing the spring 26. At this time, the outer side of the limiting ball 24 disengages from the two locking blocks 25, and the limiting ball 24 loses its support for the two locking blocks 25. The user can then slide the connecting block 21, thereby causing the two heater bodies 1 to slide, adjusting the distance between them. After the position adjustment is complete, the user releases the grip on the first handle 27 and the second handle 28. The elastic potential energy of the spring 26 is released, pushing the connecting rod 23 outwards. The limiting ball 24 then again presses against the outer side of the two locking blocks 25. At this time, the anti-slip strip 29 on one side of the locking block 25 engages with the trapezoidal passage on the inner side of one end of the limiting plate 215. Pressure is applied to the inner wall of the tank to limit the connection block 21. The spacing can be dynamically adjusted according to the actual heating requirements through the connection mechanism 2 to ensure uniform heat distribution and avoid power waste caused by local overheating. When heating a large area of ​​objects, increasing the spacing between the heater bodies 1 can expand the heat coverage area and reduce the energy consumption of repeatedly heating the same area. Increasing the spacing can reduce internal heat conduction loss and allow more heat to act on the target object. By reducing the spacing between the heater bodies 1, the synergistic effect between the heater bodies 1 can be used to quickly raise the temperature, shorten the preheating time, and avoid long-term inefficient heating. Some superconducting materials also have high thermal conductivity. The thermal superconducting path can be optimized by adjusting the spacing between the heater bodies 1 to reduce energy attenuation during heat transfer. At the same time, the stability of the movement of the two heater bodies 1 can be increased by the slider 211 and the slide rail 210. The cooling fan 213 can be activated to dissipate heat from the heater bodies 1. The device can be easily moved by the two handles 214.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
