Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating equipment, and in particular to an ultra-high frequency heating unit. Background Technology
[0002] Traditional heating equipment typically consists of coal-fired boilers or resistance heating systems. In terms of thermal efficiency, coal-fired boilers generally have a thermal efficiency of 60%-80% (mainly due to flue gas and heat loss), while resistance heating systems typically have a thermal efficiency of 85%-90% (due to surface heat loss). In terms of energy conservation and environmental protection, coal-fired boilers cause severe pollution and require desulfurization and denitrification equipment, while resistance heating systems have higher energy consumption. In terms of safety, coal-fired boilers pose risks of explosion and carbon monoxide poisoning, while resistance heating systems have the risk of electric leakage and can cause burns due to high surface temperatures. In terms of installation, coal-fired boilers require a large area of land and are complex to install; they also require frequent maintenance (ash cleaning, descaling, and furnace inspection).
[0003] To address the aforementioned issues, an electromagnetic induction heating method has emerged in the prior art. This method utilizes the principle of electromagnetic induction to convert electrical energy into heat energy. Traditional electromagnetic induction water heaters typically use metal pipes as the heating element, around which an electromagnetic coil is wound to heat the water. However, the heating element in the prior art is usually cylindrical, resulting in uneven heating of the water inside during the heating process. That is, the water near the heating element is heated more, while the water in the center is heated less, leading to poor heat exchange. To address this problem, this application proposes an ultra-high frequency heating unit. Utility Model Content
[0004] The purpose of this invention is to solve the problem of poor heat exchange effect of the heating element in electromagnetic induction heating in the prior art, and to propose an ultra-high frequency heating unit.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An ultra-high frequency heating unit includes a casing, a heating element is disposed inside the casing, an electromagnetic induction heating structure is disposed around the heating element, a turbulence structure is disposed inside the heating element, and a water inlet pipe is disposed on the water inlet pipe.
[0006] Preferably, the heating body is provided with a cavity for containing water, with a water outlet at the top and a water inlet at the bottom, and the turbulence structure is located inside the cavity.
[0007] Preferably, one end of the water inlet pipe is connected to the water inlet of the heating element, and the water inlet pipe is in communication with the interior of the heating element.
[0008] Preferably, a water inlet connector is fixedly installed on the lower back of the chassis, and a water pump is installed between the other end of the water inlet pipe and the water inlet connector.
[0009] Preferably, the top of the heating element is provided with a water outlet pipe, one end of the water outlet pipe is connected to a water outlet and the water outlet pipe is in communication with the interior of the heating element, the other end of the water outlet pipe is fixedly provided with a water outlet connector, the water outlet connector is fixedly provided in the middle of the back of the casing, and a heat insulation layer is provided on the water outlet pipe.
[0010] Preferably, the heat exchange structure includes a heat exchange cylinder, which is sleeved on the water inlet pipe, and heat exchange plates are fixedly installed on the heat exchange cylinder.
[0011] Preferably, the turbulence structure includes a turbulence plate and a spiral blade, wherein the turbulence plate is fixedly disposed on the inner wall of the heating body, and the spiral blade is fixedly disposed at the inner end of the turbulence plate.
[0012] Preferably, the electromagnetic induction heating structure includes a coil, which is spirally wound around the outer ring surface of the heating body.
[0013] Preferably, the bottom of the chassis is provided with heat dissipation holes, and both sides of the upper part of the chassis are provided with cooling fans.
[0014] Compared with the prior art, this utility model provides an ultra-high frequency heating unit with the following beneficial effects.
[0015] 1. This utility model, by setting a turbulence component in the heating body, can, on the one hand, make the water form turbulence in the heating body to improve the heat exchange effect, and on the other hand, increase the heat exchange area to further improve the heat exchange effect, thereby solving the problem of uneven heating caused by the heating body of electromagnetic induction heating in the prior art.
[0016] 2. This utility model can exchange heat generated inside the chassis by setting a heat exchange structure on the water inlet pipe. The cold water in the water inlet pipe is used to cool the inside of the chassis, and at the same time, it can also achieve the effect of preheating the water. The heat generated inside the chassis is mainly the heat leakage of the heating element and the heat generated by the coil itself.
[0017] 3. This utility model, by setting an insulation layer on the water outlet pipe, can prevent heat loss during the discharge process of heated water, thus ensuring the temperature of the outlet water.
[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0028] Please refer to Figures 1-7 An ultra-high frequency heating unit includes a casing 1, a heating element 5 is provided inside the casing 1, an electromagnetic induction heating structure is provided around the heating element 5, a turbulence structure is provided inside the heating element 5, and a water inlet pipe 7 is provided on the water inlet pipe 7.
[0029] In a specific embodiment of this utility model, the electromagnetic induction heating structure enables the heating of water using electromagnetic induction. Compared with traditional heating methods, it has advantages such as high thermal efficiency, zero emissions, power consumption only, compliance with environmental protection policies, and a water-electricity-wind heating method (the heating element 5 has no direct contact with the circuit), eliminating the risk of leakage and fire. It is also compact, lightweight, requires no chimney or coal storage, and maintenance only requires cleaning the heating element 5, without complex procedures. The turbulence structure within the heating element 5 achieves water turbulence, improving heat exchange, and increases the heat exchange area, further enhancing the heat exchange effect and enabling rapid water temperature increase, reducing heating time and energy consumption, thus achieving energy savings. The heat exchange structure on the inlet pipe 7 cools the inside of the casing 1 and preheats the water. Cooling the inside of the casing 1 prevents overheating of the coil 6, which would increase resistance and damage over time.
[0030] The heating element 5 has a cavity for holding water, an outlet at the top, an inlet at the bottom, and a turbulence structure inside the cavity. In use, the heating element 5 generates heat under the action of the electromagnetic induction heating structure to heat the water passing through the heating element 5. Water enters from the inlet of the heating element 5 and exits from the outlet.
[0031] One end of the water inlet pipe 7 is connected to the water inlet of the heating element 5, and the water inlet pipe 7 is connected to the interior of the heating element 5.
[0032] A water inlet connector 12 is fixedly installed on the lower back of the chassis 1, and a water pump 9 is installed between the other end of the water inlet pipe 7 and the water inlet connector 12.
[0033] Specifically, the inlet of the water pump 9 is connected to the water inlet connector 12, the outlet of the water pump 9 is connected to the other end of the water inlet pipe 7, and the water inlet connector 12 is connected to an external water source through a pipeline. When in use, the water pump 9 is used to pump water to the heating element 5.
[0034] The top of the heating element 5 is provided with a water outlet pipe 4. One end of the water outlet pipe 4 is connected to the water outlet and the water outlet pipe 4 is connected to the interior of the heating element 5. The other end of the water outlet pipe 4 is fixedly provided with a water outlet connector 11. The water outlet connector 11 is fixedly provided in the middle of the back of the casing 1. An insulation layer 10 is provided on the water outlet pipe 4.
[0035] Specifically, the water outlet connector 11 is connected to the user area through a pipeline; the insulation layer 10 is made of high temperature resistant and low thermal conductivity insulation material, such as rock wool, aluminum silicate fiber or polyurethane foam, and is wrapped around the outside of the water outlet pipe 4.
[0036] To further improve the safety of this device, a temperature sensor is installed on the heating element 5 to monitor the temperature of the heating element 5 and prevent overheating; a pressure gauge is installed on the water outlet pipe 4 to monitor the water pressure and prevent overpressure; all of the above settings can adopt existing conventional settings.
[0037] The heat exchange structure includes a heat exchange cylinder 13, which is fitted onto the water inlet pipe 7. Heat exchange plates 8 are fixedly installed on the heat exchange cylinder 13. The inner diameter of the heat exchange cylinder 13 matches the outer diameter of the water inlet pipe 7, so that the inner ring surface of the heat exchange cylinder 13 is tightly attached to the outer ring surface of the water inlet pipe 7, achieving a better heat exchange effect. Several heat exchange plates 8 are evenly arranged on the heat exchange cylinder 13 to increase the heat exchange area. During use, the heat generated by the heating element 5 and the heat generated by the coil 6 inside the casing 1 radiates outward and can also radiate to the heat exchange plates 8. Since the heat exchange structure is located on the water inlet pipe 7, and the temperature of the water inlet pipe 7 is relatively low, this heat can be exchanged, achieving cooling while slightly preheating the water in the water inlet pipe 7. This improves the heating speed of the water to a certain extent and also achieves the effect of saving resources.
[0038] The turbulence structure includes a turbulence plate 14 and a spiral blade 15. The turbulence plate 14 is fixedly disposed on the inner wall of the heating body 5, and the spiral blade 15 is fixedly disposed on the inner end of the turbulence plate 14.
[0039] Specifically, multiple baffles 14 are arranged in a circumferential array and evenly distributed on the inner wall of the heating body 5. The baffles 14 are inclined so that when water passes through, they can block the water and change its flow direction. At the same time, the baffles 14 can increase the heat exchange area, so that the water in the middle can also directly participate in heat exchange. The outer side of the spiral blades 15 does not contact the inner wall of the heating body 5. The spiral blades 15 can further increase the heat exchange area. At the same time, in conjunction with the baffles 14, the water is turbulent, which further improves the heat exchange effect.
[0040] The heating element 5 is preferably made of a high magnetic permeability metal material, such as carbon steel, 430 stainless steel or cast iron. The better the magnetic permeability, the higher the efficiency of converting the magnetic field into eddy currents. The baffle plate 14 and the spiral blade 15 are made of the same material as the heating element 5.
[0041] The electromagnetic induction heating structure includes a coil 6, which is spirally wound on the outer ring surface of the heating body 5, and also includes an ultra-high frequency inverter for supplying high-frequency current into the coil 6; the coil 6 is preferably made of oxygen-free pure copper wire.
[0042] In use, the ultra-high frequency inverter converts the industrial frequency AC power into ultra-high frequency current, which is then fed into coil 6. Coil 6 generates a strong alternating magnetic field, which acts on the heating element 5, causing eddy currents to be generated inside it. The eddy currents generate heat due to the resistance, causing the heating element 5 to heat up rapidly, thereby heating the water flowing inside the heating element 5. In addition, the temperature of the medium can be monitored in real time by a temperature sensor and fed back to the control system to dynamically adjust the output power, ensuring that the heating temperature is stable within the set range. This setting is a conventional setting.
[0043] The bottom of the chassis 1 is provided with ventilation holes 2, and cooling fans 3 are provided on both sides of the upper part of the chassis 1. The ventilation holes 2 and cooling fans 3 can help dissipate heat when the internal temperature of the chassis 1 is too high, thus preventing the internal temperature of the chassis 1 from becoming too high.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
