Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transformer equipment technology, specifically a small transformer for household appliances with rapid heat dissipation. Background Technology
[0002] Transformers are important components in household appliances, primarily used to change AC voltage. During operation, small transformers generate a significant amount of heat in their winding coils. If heat dissipation is insufficient, the transformer temperature can become excessively high, affecting its performance and lifespan, and potentially even posing safety hazards.
[0003] In current technology, small transformers for household appliances typically rely on natural heat dissipation from the casing or simple fan cooling, which has low heat dissipation efficiency and is difficult to meet the heat dissipation requirements of long-term high-load operation. Especially in summer when the ambient temperature is high, the transformer is more prone to failure due to overheating. Therefore, a small transformer for household appliances with rapid heat dissipation is proposed to address the above problems. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A small transformer for household appliances with rapid heat dissipation, comprising a mounting plate; a protective shell is fixedly connected to the middle part of the top of the mounting plate; a first connecting plate is fixedly connected to one side of the protective shell; a second connecting plate is fixedly connected to one side of the protective shell away from the first connecting plate; cooling pipes are fixedly connected to the opposite sides of the first and second connecting plates; a water inlet pipe is fixedly connected to the side of the first connecting plate away from the cooling pipe; a cooler is fixedly connected to the other side of the water inlet pipe; a water outlet pipe is fixedly connected to the side of the cooler away from the water inlet pipe; and the other side of the water outlet pipe is connected to the second connecting plate. The cooling pipes are symmetrically arranged.
[0006] Preferably, the cooling pipes are equidistantly distributed between the first connecting plate and the second connecting plate.
[0007] Preferably, an iron core is fixedly connected to the bottom of the inner wall of the protective shell, a winding coil is sleeved on the outer surface of the iron core, and a protective cover is fixedly connected to the top of the protective shell.
[0008] Preferably, a ventilation opening is provided in the middle of the protective cover, a cooling fan is fixedly connected to the top of the ventilation opening, and a dustproof net is fixedly connected to the top of the cooling fan.
[0009] Preferably, heat dissipation fins are equidistantly arranged on the outer side of the protective shell, and the heat dissipation fins are symmetrically arranged.
[0010] Preferably, heat-dissipating silicone is fixedly provided around the inner wall of the protective shell.
[0011] The beneficial effects of this utility model are:
[0012] By setting up symmetrical and equidistantly distributed cooling pipes, in conjunction with inlet pipes, coolers, and outlet pipes to form a circulating cooling system, heat from the protective casing is quickly dissipated. The reasonable layout of the iron core and winding coils, combined with the top cooling fan to accelerate internal air circulation, and the dust filter to ensure cleanliness, further enhances the heat dissipation area by setting symmetrical and equidistant heat dissipation fins on the outer side, and the heat dissipation silicone on the inner wall to enhance heat conduction. The synergy of multiple components significantly improves heat dissipation efficiency, extends the service life of the transformer, and ensures stable operation. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Specific implementation examples are given below.
[0021] Please see Figure 1 - Figure 3This utility model provides a small transformer for household appliances with rapid heat dissipation, including a mounting plate 1. A protective shell 2 is fixedly connected to the middle part of the top of the mounting plate 1. A first connecting plate 7 is fixedly connected to one side of the protective shell 2. A second connecting plate 9 is fixedly connected to the end of the protective shell 2 away from the first connecting plate 7. Cooling pipes 8 are fixedly connected to the opposite sides of the first connecting plate 7 and the second connecting plate 9. A water inlet pipe 6 is fixedly connected to the side of the first connecting plate 7 away from the cooling pipe 8. A cooler 5 is fixedly connected to the other side of the water inlet pipe 6. A water outlet pipe 10 is fixedly connected to the side of the cooler 5 away from the water inlet pipe 6. The other side of the water outlet pipe 10 is connected to the second connecting plate 9. The cooling pipes 8 are symmetrically arranged and are equidistantly distributed between the first connecting plate 7 and the second connecting plate 9.
[0022] During operation, the cooler 5, acting as the core of the cooling medium processing, cools the coolant to a low temperature with efficient heat absorption capacity. The cooled medium, after being cooled by the cooler 5, is then transported to the first connecting plate 7 via a water inlet pipe 6 connected to one side of the cooler 5. Since the first connecting plate 7 is fixedly connected to one end of multiple equidistant and symmetrically arranged cooling pipes 8, the low-temperature cooling medium is evenly distributed to each cooling pipe 8 through the first connecting plate 7. The cooling pipes 8 are installed between the first connecting plate 7 and the second connecting plate 9 on both sides of the protective shell 2, which is fixed to the top center of the mounting plate 1. When the internal components of the outer casing 2 generate heat during operation, the heat is transferred to the protective outer casing 2 and absorbed by the surrounding cooling pipes 8. During the flow process, the low-temperature cooling medium in the cooling pipes 8 continuously exchanges heat with the pipe wall of the cooling pipes 8, constantly absorbing the heat conducted from the protective outer casing 2, thereby cooling the protective outer casing 2 and its internal components. Finally, the cooling medium that has absorbed heat and increased in temperature will flow along the cooling pipes 8 to the second connecting plate 9 on the other side. The second connecting plate 9 is connected to the water outlet pipe 10 of the cooler 5. The heated cooling medium then flows back to the cooler 5 through the water outlet pipe 10, where it is cooled down again by the cooler 5.
[0023] Furthermore, such as Figure 2 The bottom of the inner wall of the protective housing 2 is fixedly connected to an iron core 12. A winding coil 13 is sleeved on the outer surface of the iron core 12. A protective cover 3 is fixedly connected to the top of the protective housing 2. A ventilation opening is provided in the middle of the protective cover 3. A cooling fan 4 is fixedly connected to the top of the ventilation opening. A dustproof net is fixedly connected to the top of the cooling fan 4.
[0024] During operation, the core of the electromagnetic system is formed by the iron core 12 at the bottom of the inner wall of the protective shell 2 and the winding coil 13 on the outer surface. When the winding coil 13 is energized, it will work with the iron core 12 to generate an electromagnetic effect to achieve the core function of the device. During this process, the electromagnetic components will continuously generate heat. The heat is transferred to the inside of the protective shell 2 through the iron core 12 and the winding coil 13. The cooling fan 4 at the ventilation port in the middle of the protective cover 3 is started. The fan blades rotate to accelerate the airflow inside the protective shell 2 and exhaust the heat generated by the electromagnetic components from the ventilation port. At the same time, the dustproof net on the top can prevent external dust from entering and affecting the operation of the internal components.
[0025] Furthermore, such as Figure 3 The protective shell 2 shown has heat dissipation fins 11 arranged at equal intervals on its outer side. The heat dissipation fins 11 are arranged symmetrically. Thermal silicone is fixedly installed around the inner wall of the protective shell 2.
[0026] During operation, when the winding coil 13 and the iron core 12 generate heat, the heat-dissipating silicone around the inner wall of the protective shell 2 first comes into play. Its excellent thermal conductivity quickly conducts the heat generated by the electromagnetic components from the surface of the iron core 12 and the winding coil 13 to the inner wall of the protective shell 2, reducing heat accumulation on the internal components. Subsequently, the heat is transferred through the protective shell 2 to the equidistantly symmetrically arranged heat dissipation fins 11 on its outer side. The heat dissipation fins 11 increase the contact area with the outside air, accelerating the natural dissipation of heat to the surrounding environment. At the same time, the original cooling system and the cooling fan 4 continue to work together: the cooling pipe 8 carries away the heat from the protective shell 2 through the circulating medium, while the cooling fan 4 accelerates the airflow inside the shell and exhausts hot air, complementing the natural heat dissipation of the heat dissipation fins 11.
[0027] Working principle: The cooler 5 first cools the coolant, which is then sent to the first connecting plate 7 through the inlet pipe 6, and then distributed to multiple symmetrically spaced cooling pipes 8. The cooling pipes 8 are installed between the first connecting plate 7 and the second connecting plate 9 on both sides of the protective shell 2. When the iron core 12 and the winding coil 13 inside the protective shell 2 generate heat, the heat is transferred to the shell and absorbed by the coolant in the cooling pipes 8. The heated liquid then flows back to the cooler 5 through the second connecting plate 9 and the outlet pipe 10 to be cooled again. At the same time, the cooling fan 4 on the protective cover 3 rotates, exhausting the hot air inside the shell through the vents, and the dust filter can block dust. In addition, the heat dissipation silicone on the inner wall of the shell can quickly transfer the heat from the iron core 12 and the winding coil 13 to the shell, and the heat dissipation fins 11 on the outer side of the shell increase the surface area to help dissipate heat.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
