Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a cooling circulation device for a high-frequency induction heating equipment. Background Technology

[0002] In modern industrial production, high-frequency induction heating technology has been widely used in many fields due to its significant advantages such as fast heating speed, high efficiency, and uniform heating. Currently, the most common cooling methods on the market are air cooling and liquid cooling. Air cooling has relatively low heat dissipation efficiency, and it is often difficult to effectively control the coil temperature when faced with the large amount of heat generated during high-frequency heating. This leads to a decline in equipment performance or even failure after prolonged operation. While some liquid cooling methods have improved heat dissipation efficiency, the design of the cooling system is not reasonable enough to fully enclose the high-frequency spiral heating coil, resulting in uneven heat dissipation and affecting the overall performance and lifespan of the heating coil. In addition, the components of these liquid cooling systems are usually fixedly connected, making the disassembly process very cumbersome when the equipment malfunctions and needs maintenance. This consumes a lot of time and labor costs, reducing the practicality of the equipment to a certain extent and failing to meet the needs of efficient and convenient maintenance in industrial production.

[0003] To address the shortcomings of the aforementioned technologies, we propose a cooling circulation device for high-frequency induction heating equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling circulation device for a high-frequency induction heating equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling circulation device for a high-frequency induction heating equipment includes a heating platform with a cooling circulation assembly on its upper side. The cooling circulation assembly includes a base plate with a lower annular cavity fixedly connected to its upper side. An upper annular cavity is screwed onto the upper side of the lower annular cavity. A long connecting pipe is fixedly connected to the side wall of the lower annular cavity, and a lower connecting pipe is fixedly connected to the end of the long connecting pipe. An upper short pipe is fixedly connected to the side wall of the upper annular cavity. A circulation pump is fixedly installed on the upper side of the upper short pipe, and an upper connecting pipe is fixedly installed on the upper side of the output end of the circulation pump. Several plug-in cylinders are fixedly installed at equal intervals on the upper sides of both the lower and upper connecting pipes, and several thin-walled transparent plastic tubes are inserted between the plug-in cylinders on both sides.

[0006] Furthermore, a sealing washer is provided at the screw connection of the upper annular cavity.

[0007] Furthermore, spiral grooves are provided on the inner walls of both the lower and upper annular cavities, and high-frequency spiral heating coils are embedded in the inner sides of the spiral grooves.

[0008] Furthermore, the high-frequency spiral heating coil is fixedly connected to two ends with a power plug, and a power socket is provided on the upper side of the heating platform corresponding to the lower side of the power plug, with the power plug inserted into the inside of the power socket.

[0009] Furthermore, both the lower and upper annular cavities are made of high-density ceramic material, and the thin-walled transparent plastic tube is made of PES plastic material.

[0010] Furthermore, a sealing plate is fixedly installed on the inner side of the lower annular cavity, and the base plate is screwed onto the upper side of the heating platform.

[0011] Furthermore, a side support is fixedly installed on the side wall of the heating platform, and a fan is fixedly installed on the side support. The air outlet of the fan is aligned with the thin-walled transparent plastic tube.

[0012] Furthermore, a control switch is fixedly installed at the end of the heating platform.

[0013] Compared with related technologies, the cooling circulation device for high-frequency induction heating equipment proposed in this utility model has the following beneficial effects: In this invention, a cooling circulation device for a high-frequency induction heating equipment utilizes a cooling circulation assembly. Within this assembly, a circulation pump activates, drawing cooling water from the upper annular cavity through an upper short pipe, the circulation pump's working chamber, an upper through pipe, a thin-walled transparent plastic pipe, a lower through pipe, a long connecting pipe, and the lower annular cavity to form a water-cooled circulation path. The lower and upper annular cavities enclose the high-frequency spiral heating coil, allowing the heat generated during operation to be transferred via the water-cooled circulation to the inside of the thin-walled transparent plastic pipe for heat exchange with the air, thus dissipating heat. Simultaneously, a side fan can be activated to accelerate airflow, further increasing the heat dissipation rate of the thin-walled transparent plastic pipe. This combination of water-cooling and air-cooling significantly improves the heat dissipation rate of the high-frequency spiral heating coil. Furthermore, all components of the cooling circulation assembly are detachable, facilitating future maintenance and repair, and enhancing practicality. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Reference Figures 1-5 A cooling circulation device for a high-frequency induction heating equipment includes a heating platform 1, on the upper side of which a cooling circulation component 5 is provided. The cooling circulation component 5 includes a base plate 51, a lower half-annular cavity 52 fixedly connected to the upper side of the base plate 51, an upper half-annular cavity 53 screwed onto the upper side of the lower half-annular cavity 52, a long connecting pipe 55 fixedly connected to the side wall of the lower half-annular cavity 52, a lower connecting pipe 56 fixedly connected to the end of the long connecting pipe 55, an upper short pipe 58 fixedly connected to the side wall of the upper half-annular cavity 53, a circulation pump 59 fixedly installed on the upper side of the upper short pipe 58, an upper connecting pipe 510 fixedly installed on the upper side of the output end of the circulation pump 59, and several plug-in tubes 57 fixedly installed at equal intervals on the upper sides of the lower connecting pipe 56 and the upper connecting pipe 510, with several thin-walled transparent plastic tubes 511 inserted between the several plug-in tubes 57 on both sides.

[0018] In this method, spiral grooves 54 are provided on the inner walls of the lower half-annular cavity 52 and the upper half-annular cavity 53. A high-frequency spiral heating coil 6 is embedded in the inner side of the spiral groove 54. Power plugs 61 are fixedly connected to both ends of the high-frequency spiral heating coil 6. A power socket is provided on the upper side of the heating table 1 corresponding to the lower side of the power plug 61. The power plug 61 is inserted into the inner side of the power socket.

[0019] With the above-described configuration, the power connector 61 is used to pass a high-frequency alternating current into the high-frequency spiral heating coil 6. When the high-frequency alternating current passes through the spiral coil, a high-frequency alternating magnetic field is generated around the coil. If a metal workpiece is placed within this magnetic field, according to the law of electromagnetic induction, an induced electromotive force will be generated inside the metal workpiece, thus forming closed eddy currents. Because the metal workpiece itself has resistance, the eddy currents will generate Joule heat during their flow due to the resistance, causing the temperature of the metal workpiece to rise rapidly. This is a prior art method and will not be elaborated further here.

[0020] In this method, a side support 3 is fixedly installed on the side wall of the heating table 1, and a fan 4 is fixedly installed on the side support 3. The air outlet of the fan 4 is aligned with the thin-walled transparent plastic tube 511, and a control switch 2 is fixedly installed at the end of the heating table 1.

[0021] With the above-mentioned setup, when the fan 4 starts, it can accelerate the airflow speed at the thin-walled transparent plastic tube 511, thereby accelerating the rate of heat exchange between the thin-walled transparent plastic tube 511 and the air, and further improving the heat dissipation efficiency of the water cooling cycle.

[0022] In this method, a sealing washer 512 is provided at the screw connection of the upper annular cavity 53.

[0023] By setting the sealing gasket 512 in the above manner, when the lower half-ring cavity 52 and the upper half-ring cavity 53 are screwed together, the internal chambers can maintain a mating and sealing state.

[0024] In this method, both the lower annular cavity 52 and the upper annular cavity 53 are made of high-density ceramic material, and the thin-walled transparent plastic tube 511 is made of PES plastic material.

[0025] With the above-mentioned setup, both the high-density ceramic material and the PES plastic material are non-magnetic. As a result, when the high-frequency spiral heating coil 6 is working, the lower half-ring cavity 52, the upper half-ring cavity 53, and the thin-walled transparent plastic tube 511 are not affected by the working magnetic field of the high-frequency spiral heating coil 6. In addition, the long-term operating temperature of the PES plastic material is 180°C, and it can withstand a high temperature of 220°C for a short period of time, which has good heat resistance.

[0026] In this configuration, a sealing plate 513 is fixedly installed on the inner side of the lower annular cavity 52, and a base plate 51 is screwed onto the upper side of the heating platform 1.

[0027] With the above-mentioned configuration, the sealing plate 513 ensures that the cooling water in the water-cooled cavity formed after the lower half-annular cavity 52 and the upper half-annular cavity 53 are screwed together will circulate once before returning to the original flow during water cooling circulation. This allows the cooling water to dissipate heat around the inner high-frequency spiral heating coil 6, ensuring uniform heat dissipation.

[0028] The working principle of the cooling circulation device for a high-frequency induction heating equipment provided by this utility model is as follows: During use, while the high-frequency spiral heating coil 6 is working, the operator starts the cooling circulation system via the control switch 2 at the end of the heating platform 1. At this time, the circulation pump 59 starts working, driving the cooling water to flow in the cooling circulation assembly 5, forming a water-cooled circulation path. The specific process is as follows: after the circulation pump 59 starts, the cooling water in the upper annular cavity 53 is drawn into the working chamber of the circulation pump 59 through the upper short pipe 58, and then discharged through the upper through pipe 510 at the output end of the circulation pump 59. The plug-in sleeve 57 on the upper through pipe 510 is plugged into and connected to the thin-walled transparent plastic tube 511. Cooling water enters the thin-walled transparent plastic tube 511, then flows into the lower through pipe 56 through the plug-in sleeve 57, then flows into the lower half-annular cavity 52 through the long connecting pipe 55, and finally returns to the upper half-annular cavity 53. This cycle repeats. Inside the lower half-annular cavity 52 and the upper half-annular cavity 53, there are spiral grooves 54 on the inner wall, in which the high-frequency spiral heating coil 6 is embedded. Therefore, when the cooling water flows in the cavity of the half-annular cavity, it will tightly surround the high-frequency spiral heating coil 6, fully absorbing the heat generated during its operation. At the same time, the sealing plate 513 on the inner side of the lower half-annular cavity 52 plays a key role. It prevents the cooling water from flowing back directly during water cooling circulation. Instead, it needs to circulate once before flowing into the lower through pipe 56 through the long connecting pipe 55. This ensures that the cooling water can fully and evenly contact the high-frequency spiral heating coil 6, dissipating heat around its periphery and ensuring the uniformity of heat dissipation. To further improve heat dissipation efficiency, the fan 4 installed on the side support 3 on the side wall of the heating platform 1 will also start simultaneously. The air outlet of the fan 4 is aligned with the thin-walled transparent plastic tube 511, and the air blown out by it accelerates the airflow around the thin-walled transparent plastic tube 511. When the cooling water that has absorbed heat flows in the thin-walled transparent plastic tube 511, the heat will be transferred to the air through the tube wall, and the accelerated airflow can quickly carry away this heat, thereby accelerating the heat dissipation rate of the thin-walled transparent plastic tube 511 and realizing a highly efficient heat dissipation method that combines water cooling circulation and air cooling.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
