Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more specifically, to a transformer with high-frequency magnetic materials. Background Art

[0002] The working principle of a high-frequency transformer is based on electromagnetic induction. When an alternating current passes through a wire (referred to as the primary coil), a magnetic field is generated around the wire. This magnetic field induces an electromotive force in the secondary coil, thereby achieving voltage conversion.

[0003] Regarding transformers, there are many existing technologies, such as:

[0004] Chinese Patent Publication No. CN119140a383B discloses a high-frequency transformer, including a transformer body and a heat dissipation mechanism. The heat dissipation mechanism includes an air-cooling fan and a cooling pipeline. The air-cooling fan is configured to provide forced air-cooling for the transformer body when the temperature of the transformer body reaches a first temperature threshold; the cooling pipeline includes a cooling pipe wound around the outer periphery of the transformer body, and the liquid inlet of the cooling pipe is configured to receive a coolant when the temperature of the transformer body reaches a second temperature threshold, thereby providing water-cooling for the transformer body.

[0005] It can be seen that the heat generated by a high-frequency transformer during operation mainly comes from the losses of the iron core and the windings, and the greater the working load of the high-frequency transformer, the more heat is generated during its operation. In the existing technology, most heat dissipation of transformers adopts a combination of air-cooling and water-cooling.

[0006] However, when the transformer is installed on the ground, in order to prevent rain, a support frame is usually provided at the bottom of the transformer to keep the transformer at a certain distance from the ground. Thus, in a high-temperature and windless environment in summer, since the support frame encloses the heat at the bottom of the transformer, it prevents the external air from exchanging heat with the heat, resulting in the heat dissipated from the bottom of the transformer accumulating at the bottom, causing the phenomenon of excessive heat at the bottom. Secondly, due to the air-cooling heat dissipation method, the fans are mostly arranged on one side of the transformer, resulting in a better heat dissipation effect on the windward side of the transformer than on the leeward side, causing the phenomenon of uneven heat dissipation. If fans are arranged around the transformer, although it can achieve a good heat dissipation effect, its subsequent maintenance cost and power consumption will also increase accordingly. Summary of the Invention

[0007] The purpose of the present invention is to provide a transformer with high-frequency magnetic materials to solve the problems raised in the above background art.

[0008] To achieve the above-mentioned purpose, the present invention aims to provide a transformer with high-frequency magnetic materials, including a transformer body, a lower base and an upper base, a heat dissipation fan is arranged on the upper base on one side of the transformer body, a liquid cooling system is arranged on the transformer body, a trigger mechanism is arranged on the top of the transformer body, the trigger mechanism is used to control the start and stop of the heat dissipation fan and the liquid cooling system according to the temperature change inside the transformer body, and air induction plates are rotatably arranged on the upper base on both sides of the leeward side of the transformer body, and an air guide box is slidably arranged on the upper base between the air induction plates on both sides. When the heat dissipation fan and the liquid cooling system are working at the same time, the air induction plates are used to guide the airflow flowing through the side of the transformer body to the back of the transformer body, so that the two airflows flow alternately to take away the heat from the leeward side of the transformer body, and the air guide box is used to guide the airflow to be discharged from between the upper base and the lower base, so as to form a negative pressure at the bottom of the transformer body, take away the heat accumulated at the bottom of the transformer body, and reduce the accumulation of heat at the bottom of the transformer body.

[0009] As a further improvement of the present technical solution, an air induced draft plate is provided on the leeward side of the transformer body. Under normal conditions, the air induced draft plates on both sides are inclined in an outward-facing "X" shape and are used to guide the airflow on both sides of the transformer body toward the leeward side so that the airflow on the leeward side can flow, and a return spring is elastically connected between the bottom of the air induced draft plate and the surface of the upper base.

[0012] As a further improvement of the technical solution, a sliding rod passing through the outer shell is fixedly provided on the movable plate, and a retractable rod extending toward the air induced plate is fixedly provided at the bottom of the sliding rod. The end of the retractable rod is bent downward near the air induced plate to form a bent end, and a first wedge block is provided in contact with the bent end.

[0013] As a further improvement of the present technical solution, the first wedge block is fixedly arranged with the air induced draft plate, so that when the internal temperature of the transformer body rises, the air induced draft plate is moved closer to the transformer body by using the bent end, thereby narrowing the air flow channel formed between the air induced draft plate and the transformer body.

[0014] As a further improvement of the present technical solution, a second wedge block is fixedly provided at the inner bottom of the air duct plate away from the rotation connection with the upper base, and the second wedge block is used to lift the air guide box. Auxiliary rods slidably connected to the second wedge block are fixedly provided on both sides of the air guide box, and the auxiliary rods are located on the rotation path of the second wedge block.

[0015] As a further improvement of the present technical solution, the air guide box is located in a through groove opened on the upper base, one end of the air guide box is an air inlet end, and the other end is an air outlet end, and the connection between the air inlet end and the air outlet end is a duct. Under normal conditions, the top of the air inlet end is horizontally flush with the upper surface of the upper base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the transformer with high-frequency magnetic material, under the action of the bent end and the first wedge block, the bent end slides along the inclined surface of the first wedge block, and the air induced plates on both sides rotate clockwise and counterclockwise respectively and overcome the elastic potential energy of the reset spring. As the rotation amplitude of the air induced plates increases, the distance between the air flow channels between the air induced plates and the transformer body decreases, so that the air flow flowing through the air flow channel can pass quickly, thereby increasing the pressure difference on the back of the transformer body, so as to use the pressure difference to take away more heat from the leeward side, which is helpful to dissipate heat from the leeward side of the transformer body.

[0019] 2. In the transformer with high-frequency magnetic material, the second wedge block is used to abut against the auxiliary rod on the air guide box, so that the auxiliary rod and the air guide box keep moving vertically upward, and the air inlet end on the air guide box guides the airflow into the exhaust end and discharges it, so as to form a flowing airflow between the lower base and the upper base, so that the air circulates between the lower base and the upper base, reduce the heat accumulation at the bottom of the transformer body, and further improve the heat dissipation effect of the transformer body.

[0036] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0038] As Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, a transformer with a high-frequency magnetic material is provided, which includes a transformer body 100, a lower base 101, and an upper base 102. A cooling fan 110 is provided on the upper base 102 on one side of the transformer body 100. A liquid cooling system 120 is provided on the transformer body 100. A trigger mechanism 140 is provided on the top of the transformer body 100. The trigger mechanism 140 is used to control the start and stop of the cooling fan 110 and the liquid cooling system 120 according to the temperature change inside the transformer body 100.

[0039] Among them, the transformer body 100 is used to provide functions of a high-frequency transformer known in the prior art such as voltage conversion and current transfer, and the transformer body 100 has different temperatures when operating under different working loads. When the temperature inside the transformer body 100 reaches a preset first gradient temperature threshold, the trigger mechanism 140 controls the cooling fan 110 to start working, and at this time, the liquid cooling system 120 is in a stopped state. When the temperature inside the transformer body 100 rises to a second gradient temperature threshold, the trigger mechanism 140 controls the cooling fan 110 and the liquid cooling system 120 to work simultaneously, so as to be able to select a reasonable cooling method according to the working load of the transformer body 100 to dissipate heat from it, preventing the transformer body 100 from being at a high temperature for a long time and affecting its performance.

[0040] It should be noted that: the above-mentioned first gradient temperature threshold and second gradient temperature threshold can be specifically set according to the usage situation, which belongs to the prior art and will not be elaborated here.

[0041] Secondly, air guide plates 130 are rotatably provided on the upper base 102 on both sides of the leeward side of the transformer body 100, and an air guide box 150 is slidably provided on the upper base 102 between the air guide plates 130 on both sides. When the heat dissipation fan 110 and the liquid cooling system 120 are working at the same time, the air guide plates 130 are used to guide the airflow flowing through the side of the transformer body 100 to the back of the transformer body 100, so that the two airflows flow alternately to take away the heat from the leeward side of the transformer body 100, and the air guide box 150 is used to guide the airflow to be discharged from between the upper base 102 and the lower base 101, so as to form a negative pressure at the bottom of the transformer body 100, take away the heat accumulated at the bottom of the transformer body 100, reduce the heat accumulation at the bottom of the transformer body 100, and improve the multi-directional heat dissipation effect of the transformer body 100.

[0042] That is, when the temperature in the transformer body 100 is at the first gradient temperature threshold, the heat dissipation fan 110 starts to work to dissipate heat from the transformer body 100. Figure 2 As shown by the middle arrow, the arrows represent the direction of airflow. The side of the transformer body 100 close to the heat dissipation fan 110 is the windward side, and the opposite side is the leeward side. As a result, the cooling effect on the leeward side is uneven compared with the cooling on the windward side.

[0043] To this end, based on the above diagram, combined with Figure 4 As shown, an air induced draft plate 130 is provided on the leeward side of the transformer body 100. Under normal conditions, the air induced draft plates 130 on both sides are inclined in an outward-facing shape and are used to guide the airflow on both sides of the transformer body 100 to the leeward side so that the airflow on the leeward side can flow, and a return spring 133 is elastically connected between the bottom of the air induced draft plate 130 and the surface of the upper base 102.

[0044] Combination Figure 5 and Figure 6 As shown, the specific structure of the trigger mechanism 140 is shown. The trigger mechanism 140 includes a primary memory spring 141 and a secondary memory spring 142 arranged on the top of the transformer body 100. The primary memory spring 141 and the secondary memory spring 142 are both located in a housing 140a fixedly arranged on the top of the transformer body 100. The primary memory spring 141 is fixedly arranged with the secondary memory spring 142. One end of the secondary memory spring 142 is fixedly connected to the inner wall of the trigger mechanism 140. The deformation temperature of the secondary memory spring 142 is greater than the deformation temperature of the primary memory spring 141.

[0045] One end of the primary memory spring 141 away from the secondary memory spring 142 is fixedly connected to a movable plate 145, and a trigger member 146 is fixedly arranged on one side of the movable plate 145. The trigger member 146 is sequentially arranged on the horizontal moving path, and a primary signal trigger point 160 and a secondary signal trigger point 161 are sequentially arranged on the top of the transformer body 100. The primary signal trigger point 160 and the secondary signal trigger point 161 are connected to the control system on the transformer body 100.

[0046] It is worth noting that the deformation temperature of the primary memory spring 141 corresponds to the first gradient temperature threshold, and similarly, the deformation temperature of the secondary memory spring 142 corresponds to the second gradient temperature threshold.

[0047] On the other hand, a sliding rod 143 passing through the shell 140a is fixedly provided on the movable plate 145, and a retracting rod 144 extending toward the air induced plate 130 is fixedly provided at the bottom of the sliding rod 143. The end of the retracting rod 144 is bent downward near the air induced plate 130 to form a bent end, and a first wedge block 131 is fitted with the bent end. The first wedge block 131 is fixedly provided with the air induced plate 130, so that when the internal temperature of the transformer body 100 rises, the bent end can be used to move the air induced plate 130 closer to the transformer body 100, thereby shrinking the air flow channel formed between the air induced plate 130 and the transformer body 100.

[0048] Working principle: When the temperature in the transformer body 100 reaches the first gradient temperature threshold, the primary memory spring 141 is deformed, wherein the primary memory spring 141 is in an elongated state at a low temperature and in a compressed state at a high temperature. Similarly, the deformation principle of the secondary memory spring 142 is the same as that of the primary memory spring 141. Therefore, when the primary memory spring 141 is deformed, the primary memory spring 141 pulls the slide bar 143 to move, and the contraction rod 144 moves synchronously with the slide bar 143. In this process, the bending end and the first wedge are deformed. Under the action of block 131, the bent end slides along the inclined surface of the first wedge block 131, and the air guide plates 130 on both sides rotate clockwise and counterclockwise respectively and overcome the elastic potential energy of the return spring 133. As the rotation amplitude of the air guide plates 130 increases, the distance between the air flow channel between the air guide plates 130 and the transformer body 100 decreases, so that the air flow flowing through the air flow channel can pass quickly, thereby increasing the pressure difference on the back of the transformer body 100, so as to utilize the pressure difference to take away more heat from the leeward side, which is helpful to dissipate heat from the leeward side of the transformer body 100.

[0049] When the air induction plate 130 rotates in the opposite direction under the action of the return spring 133 , the air flow channel spacing between the air induction plate 130 and the transformer body 100 increases, and the external environment air flow can flow at this time to dissipate heat for the transformer body 100 .

[0050] Secondly, when the temperature inside the transformer body 100 reaches the second gradient temperature threshold, similar to the first-stage memory spring 141, at this time, the cooling fan 110 and the liquid cooling system 120 work together to dissipate heat from the transformer body 100, so as to reduce the temperature inside the transformer body 100 and improve its working performance.

[0051] It needs to be disclosed that: on the leeward side of the transformer body 100, if the air flow velocity decreases, the dynamic pressure will be converted into static pressure. If the flow velocity at the air flow channel is faster than before (due to the narrowing of the channel), then the decrease in static pressure at the air flow channel will be more significant, thus forming a larger pressure difference on the leeward side of the transformer body 100.

[0052] Furthermore, two air flows discharged from the air flow channel are staggered between the ends of the air guiding plate 130. When the staggered air flows are discharged, a negative pressure is formed on the transformer body 100, so as to take away the heat gathered on the back of the transformer body 100 and improve the heat dissipation effect of the transformer body 100. At the same time, in combination with Figure 7 and Figure 8 As shown in, during the rotation of the air guiding plate 130, since the second wedge-shaped block 132 is fixedly arranged at the inner bottom of the air guiding plate 130 far away from the rotation connection with the upper base 102, the second wedge-shaped block 132 is used to lift the air guiding box 150. The auxiliary rods 152 slidably connected with the second wedge-shaped block 132 are fixedly arranged on both sides of the air guiding box 150, and the auxiliary rods 152 are located on the rotation path of the second wedge-shaped block 132.

[0053] In addition, the air guiding box 150 is located in the through groove 103 opened on the upper base 102. One end of the air guiding box 150 is the air inlet end, and the other end is the air outlet end. The connection between the air inlet end and the air outlet end is a conduit. Under normal conditions, the top of the air inlet end is flush with the upper surface of the upper base 102 in the horizontal direction. When the air inlet end moves upward, the air inlet end and the air outlet end are conducted, so as to realize guiding the air flow above the upper base 102 into and discharging between the upper base 102 and the lower base 101. Among them, the air flow direction in the air guiding box 150 refers to the arrow e to f in Figure 7 as shown.

[0054] In this way, during the rotation of the air guiding plate 130, the air guiding plate 130 can not only guide the air flow on the side of the transformer body 100, but also drive the second wedge block 132 to move, and utilize the second wedge block 132 to abut against the auxiliary rod 152 on the air guiding box 150, so that the auxiliary rod 152 and the air guiding box 150 keep moving vertically upward. The air inlet end on the air guiding box 150 guides the air flow into the exhaust end and discharges it. That is to say, when the air inlet end of the air guiding box 150 moves upward to exceed the upper surface of the upper base 102 in the horizontal direction, the air guiding box 150 divides the air flow above the upper base 102 into two streams. Among them, one stream of air directly flows away between the two side air guiding plates 130, and the other stream is diverted by the air guiding box 150 to flow away between the lower base 101 and the upper base 102, thereby forming a flowing air flow between the lower base 101 and the upper base 102, enabling the air circulation between the lower base 101 and the upper base 102, reducing the accumulation of heat at the bottom of the transformer body 100, and further improving the heat dissipation effect of the transformer body 100.

[0055] To ensure the stability of the air guiding box 150 during movement, a vertical rod 151 for keeping the air guiding box 150 moving in the vertical direction is fixedly arranged on the lower base 101. The vertical rods 151 are slidably arranged between each other to maintain the stability of the air guiding box 150 during reciprocating up and down movement.
