Description

Technical Field

[0001] This utility model relates to the field of electromagnetic heating technology, specifically an electromagnetic cooling and heating device. Background Technology

[0002] Currently, electromagnetic heating is widely used in household and commercial appliances. It primarily utilizes the principle of eddy current heating through magnetic field induction. A medium-frequency or high-frequency alternating current passes through a coil to generate a medium-frequency or high-frequency magnetic field. When the magnetic field lines pass through a magnetically conductive metal material, countless eddy currents are generated within the metal. The high-speed collisions of these eddy currents cause the metal material to heat up rapidly, thus achieving the purpose of heating the metal. However, during continuous high-power heating, the coil generates a significant amount of heat. Current technology relies on fans for heat dissipation, but this alone is insufficient to effectively remove heat from the coil, leading to excessively high coil temperatures and potentially causing the coil to burn out, posing safety hazards. Furthermore, heat loss due to heat dissipation results in resource waste. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide an electromagnetic cooling and heating device to overcome the shortcomings of the prior art.

[0004] An electromagnetic cooling and heating device designed for this purpose includes a coil, which is an electromagnetic coil spirally wound from a hollow tube, and has a coil inlet and a coil outlet at its two ends, respectively. The coil inlet is connected to a liquid supply end, and the coil outlet is connected to a magnetically heated tube, which is a hollow tube wound inside the coil.

[0005] The magnetic heating tube is provided with a heating liquid inlet and a hot vapor liquid outlet at both ends. The heating liquid inlet is located on the same side as the coil liquid outlet and the two are connected to each other. The hot vapor liquid outlet is located on the same side as the coil liquid inlet.

[0006] The coil is spirally wound into a cylindrical shape, and a magnetic field cavity is provided at its center. The magnetically heated tube is spirally wound inside the magnetic field cavity.

[0007] The coil and the magnetized heating tube are mutually dependent, or a gap is formed between the coil and the magnetized heating tube.

[0008] Both the coil and the magnetized heating tube are made of metal and are either integrally formed or separately installed and then welded together.

[0009] This electromagnetic cooling and heating device also includes an IGBT module, or an IGBT module heat sink, or a MOS field-effect transistor, or a MOS field-effect transistor heat sink. The liquid at the liquid supply end flows through the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink before entering the coil. Alternatively, the liquid in the coil flows through the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink before entering the magnetically heated tube.

[0010] This electromagnetic cooling and heating device further includes a water pump, the inlet end of which is connected to the supply end, and the outlet end of which is connected to the coil inlet or the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink.

[0011] The IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink is further provided with a heat dissipation tube. The heat dissipation tube is a hollow tube, and its two ends are respectively provided with a heat dissipation inlet and a heat dissipation outlet. The heat dissipation inlet is connected to the outlet end of the water pump or the supply end, and the heat dissipation outlet is connected to the coil inlet.

[0012] The IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink is further provided with a heat sink tube. The heat sink tube is a hollow tube, and its two ends are respectively provided with a heat sink inlet and a heat sink outlet. The heat sink inlet is connected to the coil outlet, and the heat sink outlet is connected to the heating inlet.

[0013] The heat pipe is made of metal or non-metal material and is wound around the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect module heat sink.

[0014] This invention, through structural improvements, utilizes a hollow tube spirally wound into a coil, within which a similarly hollow tube magnetic heating tube is wound. The coil is then connected to the liquid supply end via its inlet and to the magnetic heating tube via its outlet, allowing liquid to sequentially enter both the coil and the heating tube. The liquid entering the coil dissipates heat quickly and efficiently, effectively reducing the coil's operating temperature and ensuring stable operation. Because the magnetic heating tube is wound inside the coil, the magnetic field generated within the coil is evenly and effectively distributed onto the heating tube, which receives the magnetic field and generates heat. The liquid entering the heating tube is then thoroughly and evenly heated, allowing the heating tube to discharge high-temperature steam or liquid. Furthermore, the liquid flowing through the coil is preheated, effectively utilizing heat resources and reducing waste. The fast and efficient liquid heating makes it widely applicable in household and commercial liquid heating equipment, with a broad range of applications. Attached Figure Description

[0024] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0026] See Figures 1-7 The electromagnetic cooling and heating device includes a coil 1, which is an electromagnetic coil made of a hollow tube spirally wound, and has a coil inlet 1.1 and a coil outlet 1.2 respectively at its two ends. The coil inlet 1.1 is connected to the liquid supply end, and the coil outlet 1.2 is connected to a magnetic heating tube 2, which is a hollow tube wound inside the coil 1.

[0027] In this embodiment, a hollow tube is spirally wound into a coil 1, and a hollow tube magnetic heating tube 2 is wound inside the coil 1. The coil 1 is then connected to the liquid supply end via the coil inlet 1.1 and to the magnetic heating tube 2 via the coil outlet 1.2, allowing liquid to sequentially enter the coil 1 and the magnetic heating tube 2. The liquid entering the coil 1 dissipates heat quickly and efficiently, effectively reducing the temperature of the coil 1 during operation and ensuring stable operation. Because the magnetic heating tube 2 is wound inside the coil 1, ... The magnetic field generated inside the coil 1 can be evenly and effectively distributed onto the magnetized heating tube 2. The magnetized heating tube 2 can receive the magnetic field of the coil 1 to a large extent and generate heat. The liquid entering the magnetized heating tube 2 can be heated comprehensively and evenly, allowing the magnetized heating tube 2 to discharge high-temperature steam or high-temperature liquid. In addition, the liquid flowing through the coil 1 can also be preheated. This not only effectively utilizes heat resources and reduces resource waste, but also heats the liquid quickly and efficiently. It can be widely used in household or commercial liquid heating equipment and has a wide range of applications.

[0028] This electromagnetic cooling and heating device includes a circuit board 4, which is electrically connected to the coil 1 to control the coil 1. In addition, the circuit board 4 generates a low voltage of less than 48V when it is working, so it can avoid the problem of user injury caused by leakage when the liquid flows in the coil 1 and the magnetic heating tube 2. It is safe and reliable to use.

[0029] The magnetic heating tube 2 is provided with a heating liquid inlet 2.1 and a hot vapor liquid outlet 2.2 at both ends. The heating liquid inlet 2.1 and the coil liquid outlet 1.2 are located on the same side and are connected to each other. The hot vapor liquid outlet 2.2 and the coil liquid inlet 1.1 are located on the same side.

[0030] In this embodiment, since the heating liquid inlet 2.1 and the coil liquid outlet 1.2, and the hot vapor liquid outlet 2.2 and the coil liquid inlet 1.1 are arranged on the same side, the space occupancy rate can be effectively reduced.

[0031] The coil 1 is spirally wound into a cylindrical shape, and a magnetic field cavity 1.3 is provided at its center. The magnetic heating tube 2 is spirally wound inside the magnetic field cavity 1.3, so that the magnetic heating tube 2 can be effectively located inside the magnetic field cavity 1.3 of the coil 1, thereby receiving the magnetic force of the magnetic field emitted by the coil 1.

[0032] The coil 1 and the magnetically heated tube 2 are mutually dependent, or a gap is formed between the coil 1 and the magnetically heated tube 2.

[0033] In this embodiment, a gap is formed between the coil 1 and the magnetic heating tube 2, and a heat insulation component 3 is provided within the gap to effectively reduce the heat transfer from the magnetic heating tube 2 to the coil 1 during heating, thus preventing the coil 1 from overheating.

[0034] Both coil 1 and magnetized heating tube 2 are made of metal materials, and they are either integrally formed or separately installed and then welded together.

[0035] In this embodiment, the coil 1 and the magnetized heating tube 2 can be made of copper or aluminum. They are set separately and then fixed to each other by welding.

[0036] Positioning components 6 are provided on the circuit board 4 corresponding to the extension tubes of the coil inlet 1.1 and the heating inlet 2.1. The extension tubes of the coil inlet 1.1 and the heating inlet 2.1 are positioned by the positioning components 6 to ensure stable assembly.

[0037] This electromagnetic cooling and heating device also includes an IGBT module, or an IGBT module heat sink, or a MOS field-effect transistor, or a MOS field-effect module heat sink 5. The liquid at the liquid supply end flows through the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect module heat sink 5 before entering the coil 1.

[0038] In this embodiment, the IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5 will generate a certain amount of heat when it is working. When the liquid flows through the IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5, it can dissipate heat and ensure stable operation. In addition, the heat from the IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5 will also be transferred to the liquid, so that the liquid can be preheated.

[0039] This electromagnetic cooling and heating device also includes a water pump 7. The inlet end of the water pump 7 is connected to the supply end, and the outlet end of the water pump 7 is connected to the coil inlet 1.1 or the IGBT module, or the IGBT module heat sink, or the MOS field effect transistor, or the MOS field effect module heat sink 5.

[0040] In this embodiment, the water pump 7 is used to pump liquid into the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink 5. The liquid dissipates heat through the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect transistor heat sink 5, and then enters the coil 1.

[0041] Specifically, the IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5 is also provided with a heat sink 8. The heat sink 8 is a hollow tube, and its two ends are respectively provided with a heat sink inlet 8.1 and a heat sink outlet 8.2. The heat sink inlet 8.1 is connected to the outlet end of the water pump 7, and the heat sink outlet 8.2 is connected to the coil inlet 1.1.

[0042] The heat pipe 8 is made of metal or non-metal materials and is wound on the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect module heat sink 5.

[0043] In this embodiment, the heat sink 8 is made of copper or aluminum and is independent of the coil 1 and the magnetic heating tube 2. The three are then fixed together by welding.

[0044] While the liquid effectively dissipates heat from the coil 1, IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5, the coil 1, IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5 also conduct secondary heat transfer to the liquid, effectively preheating the liquid. This allows the liquid to be heated quickly and efficiently after entering the magnetic heating tube 2. Example 2

[0045] See Figure 8 The electromagnetic cooling and heating device differs from the first embodiment in that:

[0046] The liquid inside coil 1 flows through the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect module heat sink 5, and then enters the magnetically heated tube 2.

[0047] Specifically, the IGBT module, or IGBT module heat sink, or MOS field-effect transistor, or MOS field-effect transistor heat sink 5 is also provided with a heat sink 8. The heat sink 8 is a hollow tube, and its two ends are respectively provided with a heat sink inlet 8.1 and a heat sink outlet 8.2. The heat sink inlet 8.1 is connected to the coil outlet 1.2, and the heat sink outlet 8.2 is connected to the heating inlet 2.1.

[0048] In this embodiment, the water pump 7 is used to draw liquid into the coil 1 and dissipate heat from the coil 1. The liquid then enters the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect module heat sink 5. The liquid dissipates heat from the IGBT module, or the IGBT module heat sink, or the MOS field-effect transistor, or the MOS field-effect module heat sink 5, and then enters the magnetic heating tube 2.

[0049] Other undescribed parts are the same as in the first embodiment. Example 3

[0050] See Figure 9 The electromagnetic cooling and heating device differs from the first embodiment in that:

[0051] The water pump 7 is directly connected to the coil 1, and the coil 1 is then directly connected to the magnetically heated tube 2.

[0052] In this embodiment, a water pump 7 is used to draw liquid into the coil 1 and dissipate heat from the coil 1. The liquid then enters the magnetically heated tube 2.
