Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer frame with efficient heat dissipation. Background Technique

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] For example, the patent document with the application number 202120496929.3 discloses a transformer with efficient heat dissipation, including a hollow plate, a top plate, and a transformer. The transformer is vertically installed at the center of the top of the hollow plate, and strip plates are horizontally arranged on a pair of symmetrical sides at the bottom of the hollow plate and are hollow. The internal structures of the two strip plates are the same, and a sleeve is vertically and fixedly connected to the inner bottom of the strip plate. A sliding plate is vertically slidably connected inside the sleeve, and a limiting mechanism for limiting the sliding plate is provided at the inner bottom of the sleeve. First heat dissipation mechanisms for dissipating heat from the transformer are provided on two symmetrical sides of the transformer, and a second heat dissipation mechanism for dissipating heat from the transformer is provided inside the hollow plate. An installation plate is horizontally installed on the top of the transformer, and the top plate is horizontally arranged directly above the transformer. A plurality of diversion grooves are opened on the top of the top plate and are evenly distributed. The utility model increases the heat dissipation effect of the heat sink on the transformer, thereby improving the service efficiency and service life of the transformer.

[0004] For similar transformers, since they will be continuously in a high-temperature environment during long-term operation, more heat will be generated inside the transformer, and a more effective heat dissipation method is needed to reduce the temperature rise to ensure the normal operation of the equipment. For transformers with insufficient heat dissipation efficiency to maintain high-intensity operation through conduction heat dissipation, heat accumulation will occur.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a transformer frame with efficient heat dissipation is proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a transformer frame with efficient heat dissipation, because during long-term operation, it will be continuously in a high-temperature environment, more heat will be generated inside the transformer, and a more effective heat dissipation method is needed to reduce the temperature rise to ensure the normal operation of the equipment. For transformers with insufficient heat dissipation efficiency to maintain high-intensity operation through conduction heat dissipation, heat accumulation will occur.

[0007] To achieve the above object, the utility model provides the following technical solutions: A transformer frame with efficient heat dissipation, including a frame body, side boxes, a fan assembly, a front heat dissipation net and a rear heat dissipation net. On the right side of the top surface of the frame body, there is a high-voltage outgoing terminal. In front of the high-voltage outgoing terminal, there is a low-voltage outgoing terminal. The fan assembly is arranged on the left side of the top surface of the frame body. The side boxes are arranged on both sides of the frame body, and side heat dissipation plates are arranged at the front and rear ends of the two side boxes. On the front surface of the frame body, there are two protective doors. On the left side of the protective doors, there are two connecting hinges. The front heat dissipation net is arranged at the center of the protective doors. The rear heat dissipation net is arranged on the rear surface of the frame body. On the bottom surface of the frame body, there are two connecting bases.

The output end of the blower is provided with an air delivery pipe. On the top surface of the inner cavity of the frame body, there is a blowing cylinder.

[0009] Further, the surface of the side heat dissipation plates is made of aluminum alloy plates with a number of diamond structures. The surfaces of the front heat dissipation net and the rear heat dissipation net are both in a honeycomb structure.

[0010] Further, one end of the air delivery pipe far away from the blower penetrates through the frame body and is connected to the blowing cylinder. The positions of the two front heat dissipation nets correspond to each other.

[0011] Further, one ends of the two connecting hinges far away from the protective doors are both installed on the left side of the front surface of the frame body.

[0012] Further, there is a handle on the right side of the protective door, and there is a connecting ear on the right side of the high-voltage outgoing terminal.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: By setting the fan assembly to blow from the inside outwards, it can more effectively guide the air flow. The frame door with a porous honeycomb structure can increase the surface area, and blowing from the inside outwards can take away the heat, further accelerating the heat dissipation speed and improving the heat dissipation efficiency. The specific content is as follows:

[0015] There are side heat dissipation plates, a front heat dissipation net and a rear heat dissipation net. The front heat dissipation net and the rear heat dissipation net with a honeycomb structure can increase the contact area between air and the inside of the frame, promote heat transfer. The rhombic side heat dissipation plates can increase the ventilation channels, promote air flow, reduce air resistance, accelerate heat dissipation. The layout of the rhombic heat dissipation holes can make the air flow more evenly over the surface of the heat dissipation plates, improving the heat dissipation efficiency.

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figures 1 to 4As shown in the figure, a transformer frame with efficient heat dissipation includes a frame body 1, side boxes 3, a fan assembly 4, a front heat dissipation net 61 and a rear heat dissipation net 8. On the right side of the top surface of the frame body 1, there is a high-voltage outgoing terminal 2, which provides a connection point for the high-voltage line to ensure efficient power transmission. In front of the high-voltage outgoing terminal 2, there is a low-voltage outgoing terminal 10, which provides an output terminal for the low-voltage line to ensure safe and reliable power output. The side boxes 3 are arranged on both sides of the frame body 1. Electrical components are placed in the side boxes 3, playing an isolation and protection role to reduce external interference. On the front surface of the frame body 1, there are two sets of protective doors 6. The protective doors 6 can be opened or closed, facilitating maintenance personnel to enter the interior of the frame body 1 for repair and inspection operations to ensure the normal operation of the equipment. On the left side of the protective door 6, there are two sets of connecting hinges 11. One end of the two sets of connecting hinges 11 away from the protective door 6 is installed on the left side of the front surface of the frame body 1. The connecting hinges 11 enable the protective door 6 to be fixed on the frame body 1 and can be flexibly opened or closed, facilitating maintenance personnel to enter the interior for operations. On the right side of the protective door 6, there is a handle 12, which provides a handle for the operator to open or close the protective door 6, facilitating maintenance and repair. On the right side of the high-voltage outgoing terminal 2, there is a connecting ear 9, which provides a connecting point for conveniently lifting and moving the frame;

[0023] The fan assembly 4 is arranged on the left side of the top surface of the frame body 1. The fan assembly 4 includes a blower 401, an air duct 402 and a blowing cylinder 403. The blower 401 is arranged on the left side of the top surface of the frame body 1. The blower 401 generates air flow through rotating blades, sucks in air and pushes it into the air duct 402 to form a power source for air flow transmission. The output end of the blower 401 is provided with the air duct 402. The air duct 402 transmits the air flow through its internal space and guides the air flow generated by the blower 401 into the blowing cylinder 403 to achieve the functions of air flow transmission and distribution. On the top surface of the inner cavity of the frame body 1, there is a blowing cylinder 403. One end of the air duct 402 away from the blower 401 penetrates the frame body 1 and is connected to the blowing cylinder 403. The blowing cylinder 403 receives the air flow transmitted by the air duct 402 and releases the air flow in a directed manner to the position where the blowing cylinder 403 is located to achieve the required air supply effect;

[0024] On the front and rear ends of both groups of side boxes 3, there are side heat dissipation plates 5. The surface of the side heat dissipation plate 5 is an aluminum alloy plate with a number of diamond-shaped structures. The surface of the side heat dissipation plate 5 has a diamond-shaped structure, which increases the surface area. Moreover, aluminum alloy has good heat conduction performance and lightweight characteristics, making it easier for heat to be conducted to the plate and then dissipated to the external environment through air convection and conduction, achieving the effect of heat dissipation and temperature reduction. The front heat dissipation net 61 is set at the center of the protective door 6. The positions of the two groups of front heat dissipation nets 61 correspond to each other. The rear heat dissipation net 8 is set on the rear end face of the frame body 1. The surfaces of the front heat dissipation net 61 and the rear heat dissipation net 8 both have a honeycomb structure. The honeycomb structure of the front heat dissipation net 61 increases the surface area of the heat dissipation surface, which is conducive to heat transfer and dissipation. At the same time, it can filter and block external foreign objects. The honeycomb structure of the rear heat dissipation net 8 increases the air outlet area of the ventilation opening, promotes air circulation, prevents blockage by dust and other sundries, and ensures the heat dissipation effect and ventilation effect of the system, ensuring the normal operation of the system. The bottom end face of the frame body 1 is provided with connection bases 7. There are two groups of connection bases 7. The connection bases 7 provide a stable supporting force. The connection bases 7 can reduce the vibration of the system and lower the noise.

[0025] In summary, as Figures 1 to 4 shown, for this transformer frame with high-efficiency heat dissipation, the frame body 1 provides the installation and fixing structure of the transformer. The high-voltage outgoing terminal 2 and the low-voltage outgoing terminal 10 are connected to the circuit to achieve the functions of electric energy transmission and voltage transformation. The connection base 7 fixes the frame body 1 and provides a supporting function. The side box 3 protects the internal equipment. The connecting hinge 11 connects the frame body 1 and the protective door 6 and provides the function of rotating support for opening and closing. The operator holds the handle 12 on the protective door 6 to pull open the protective door 6. The connecting ear 9 provides a connection point, which is convenient for lifting and moving the transformer frame;

[0026] When the transformer frame dissipates heat, the powerful air flow brought by the blower 401 in the fan assembly 4 can accelerate the heat transfer speed and help the heat be taken away faster. The air supply pipe 402 can orderly guide the air flow generated by the blower 401 to the air blowing cylinder 403. The air blowing cylinder 403 can guide the air flow into the interior of the frame body 1 for blowing and heat dissipation inside, avoiding local heat accumulation and ensuring that the air flow covers every corner of the transformer frame. The side heat dissipation plate 5 helps with heat dissipation. The layout of the diamond-shaped heat dissipation holes can make the air flow through the surface of the heat dissipation plate more evenly, thus maintaining the normal working temperature of the internal components and equipment. The honeycomb-structured front heat dissipation net 61 and rear heat dissipation net 8 can increase the contact area between the air and the interior of the frame, thereby promoting the increase in heat transfer efficiency. When the fan assembly 4 blows and dissipates heat, the heat is transferred from the inside to the outside through the side heat dissipation plate 5, the front heat dissipation net 61, and the rear heat dissipation net 8.
