Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor iron core heat dissipation structure. Background Art

[0002] A reactor, also known as an inductor, is a component used to limit current in a circuit. Its working principle is based on the law of electromagnetic induction, that is, when a conductor is energized, a magnetic field is generated around it, and this magnetic field in turn affects the flow of current. The basic structure of a reactor is composed of a coil of wire. When the reactor is connected to a circuit, it will generate a magnetic field in the opposite direction of the current. This magnetic field will resist changes in the current, thereby limiting the increase or decrease of the current.

[0003] With the rapid development of power electronics technology, reactors are indispensable components in power systems. The stability and reliability of their performance are crucial to the safe and efficient operation of the entire system. The heat dissipation of the reactor core is one of the key factors affecting its performance. The traditional heat dissipation method of the reactor core mainly relies on the contact between the heat sink and the iron wire for heat conduction and heat dissipation, but it shows obvious limitations in practical applications. First, the heat dissipation efficiency is limited. Due to the limited contact area and the thermal conductivity performance of the heat sink itself, it is difficult to meet the heat dissipation requirements of high-power and high-density reactors. Secondly, this heat dissipation method is overly dependent on the ambient temperature. The heat dissipation effect will be significantly reduced in a high temperature environment, thereby affecting the normal operation of the reactor. Therefore, seeking a more efficient and reliable heat dissipation structure has become an important research direction for reactor design.

[0004] Chinese patent document CN203760266U discloses a core heat dissipation structure of a reactor, wherein the reactor comprises an iron core and a coil, wherein the coil is composed of a wire wound outside the iron core, and the iron core is composed of a silicon steel sheet and a non-magnetic heat conductive sheet laminated together, wherein the non-magnetic heat conductive sheet is clamped between the silicon steel sheets of the iron core; however, the following defects still exist in the implementation process:

[0005] Although the device in the above-mentioned document can quickly bring the heat generated by the reactor core to the outside of the product through a non-magnetic thermal conductive sheet, thereby cooling the core, the device in the above-mentioned document uses a thermal conductive sheet to dissipate the heat from the core, resulting in limited heat dissipation efficiency and difficulty in meeting the heat dissipation requirements of high-power, high-density reactors. Moreover, this heat dissipation method is overly dependent on the ambient temperature, and the heat dissipation effect will be significantly reduced in a high temperature environment, thereby affecting the normal operation of the reactor. Utility Model Content

[0006] The utility model aims to provide a reactor core heat dissipation structure to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A reactor core heat dissipation structure comprises a plurality of reactor bodies; a connection block 1 is fixedly connected to the upper parts of the plurality of reactor bodies, a heat sink is fixedly connected to the connection block 1, a certain gap exists between the lower end of the connection block 1 and the upper part of the heat sink, a wind dispersion mechanism is fixedly connected to the lower parts of the plurality of reactor bodies, the wind dispersion mechanism comprises a connection block 2, the connection block 2 is fixedly connected to the lower parts of the plurality of reactor bodies, a guide plate is fixedly connected to the upper part of the connection block 2, an exhaust assembly is fixedly connected to one side of the guide plate, a filter structure is fixedly connected to the side of the exhaust assembly away from the connection block 2, and the inner cavities of the plurality of reactor bodies are fixedly connected to the core bodies.

[0011] A further improvement of the technical solution of the utility model is that a plurality of heat pipes are fixedly connected to the lower end of the heat sink, and the inner cavities of the connection grooves with the same center are fixedly connected to the outer surfaces of the heat pipes.

[0012] The above technical solution is adopted, in which the inner cavity of the connecting groove is fixedly connected to the outer surface of the heat pipe, so that the heat of the core body can be quickly transferred to the heat sink by using the heat pipe, and then the heat is dissipated to the environment through the large area of ​​the heat sink, thereby improving the efficiency of the entire heat dissipation system and ensuring that equipment such as reactors can still operate stably in high temperature environments; since the heat pipe uses the phase change process of the internal working fluid to transfer heat, it can achieve a large amount of heat transfer under a very small temperature difference, thereby ensuring that the heat of the core body can be quickly taken away, thereby improving the heat dissipation efficiency of the core body.

[0013] A further improvement of the technical solution of the utility model is that a plurality of airflow holes penetrating through the upper end of the guide plate and extending to the inner cavity of the guide plate are opened on the upper end of the guide plate, and the inner cavity of the airflow holes on the same axis is communicated with the inner cavity of the flow slot.

[0014] The above-mentioned technical scheme is adopted, in which the circulation groove is connected with the inner cavity of the wind hole, so that the cold air delivered to the inner cavity of the guide plate can flow to the upper part through the inner cavity of the circulation groove through the cooperation of the wind hole and the circulation groove, and then flow to the gap between the connecting block 1 and the heat sink through the holes opened on the upper part of the heat sink, and then flow to the outside from the gap, so that the heat on the core body can be taken away during the air flow, thereby enhancing the heat dissipation of the core body.

[0015] A further improvement of the technical solution of the utility model is that the filtering structure comprises a second connecting plate, the second connecting plate is symmetrically slidably connected with a slider, and the opposite surfaces of the two sliders are commonly fixedly connected with a filter plate.

[0016] By adopting the above technical solution, the cold air extracted by the exhaust component can be filtered and intercepted by the filter plate, and the dust in the air can be filtered and collected, so as to prevent the dust from entering the circulation slot device and causing damage to the electronic components inside the device.

[0017] A further improvement of the technical solution of the utility model is that the sliding block is T-shaped.

[0018] The above technical solution is adopted, in which the slider is set to a T shape, so that the slider can be used to limit the moving trajectory of the exhaust assembly when the filter plate moves, thereby facilitating the separation and installation of the filter plate and the connecting plate 2.

[0019] A further improvement of the technical solution of the utility model is that the exhaust assembly includes a connecting plate 1, a side of the connecting plate 1 close to the guide plate is fixedly connected to the guide plate, a side of the connecting plate 1 close to the connecting plate 2 is fixedly connected to the connecting plate 2, a plurality of air inlet holes are opened in the middle of the connecting plate 1, and the inner cavities of the plurality of air inlet holes are fixedly connected to motor fans.

[0020] By adopting the above technical solution, the air around the device can be extracted by the motor fan and then transported to the inner cavity of the guide plate, so that the air extracted by the motor fan can be used to dissipate the heat of the core body.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
