Description

Technical Field

[0001] This utility model belongs to the field of reactor technology, and in particular relates to a heat dissipation structure for a series reactor. Background Technology

[0002] A reactor, also known as an inductor, is a passive electrical component that operates based on the principle of electromagnetic induction. Its core structure is a coil wound with wire. Its main characteristic is that it uses the resistance of inductance to changes in current to achieve key functions such as current limiting, filtering, and reactive power compensation in power systems and electronic circuits.

[0003] For example, Chinese patent CN222734774U discloses a heat dissipation structure for a series reactor, relating to the field of heat dissipation structure technology. It includes a reactor body with a base at its bottom; a dustproof shell covers the reactor body and is connected to the base of the reactor body by screws; multiple cooling fans are fixedly installed on one side of the dustproof shell, with the air intake of the cooling fans located inside the dustproof shell; a through hole is opened on the side of the dustproof shell away from the cooling fans, and an air intake square pipe is fixedly connected to the side wall of the dustproof shell at the location of the through hole. This invention protects the reactor body by setting up a dustproof shell and providing a dedicated airflow channel for exhaust and intake. This allows external air to be filtered through the dedicated channel before entering the dustproof shell, and heat is exhausted by the cooling fans. This prevents dust from adhering to and seeping into the coils, thus avoiding the impact on heat dissipation and greatly improving the heat dissipation effect of the reactor body.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use, such as: the dust cover is fixed with bolts, making it impossible to disassemble without tools, thus preventing the reactor body from being removed; also, the filter screen becomes clogged after prolonged use, reducing its filtration efficiency and airflow; and the inability to replace the filter screen further reduces airflow and heat dissipation. Therefore, we propose a series reactor heat dissipation structure. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for a series reactor to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a heat dissipation structure for a series reactor, including a reactor body and several negative pressure fans, and further comprising: A first housing is inserted and installed on the reactor body. A second housing is inserted and installed on the reactor body and on one side of the first housing. Several negative pressure fans are fixedly installed on the second housing. A fixed shell is fixedly installed on the first housing. A limit groove is formed in the fixed shell. A fixed frame is inserted into a limiting groove. A filter screen is fixedly installed inside the fixed frame. A limiting rod is rotatably installed inside the limiting groove and at the bottom of the fixed frame. The upper end of the limiting rod extends into the fixed frame and is inserted into the fixed frame. A fixing component, located on the second housing, is used to fix the positions of the first housing and the second housing; A drive assembly, located within a fixed housing, is used to drive the limit rod to rotate.

[0007] In this technical solution, when it is necessary to dissipate heat from the reactor body, several negative pressure fans are first started to draw outside air into the fixed shell. Then, the filter screen can filter the air, and the dust in the air will be collected on the top of the filter screen. Then, the dust-free air enters the first shell and the second shell, which can cool the reactor body. At the same time, the hot air in the first shell and the second shell is discharged to the outside through several negative pressure fans, which can effectively dissipate heat from the reactor body. When the fixed frame needs to be disassembled and cleaned, the set drive component can drive the limit rod to rotate forward. After the limit rod is disengaged from the fixed frame, the staff can pull the fixed frame and filter screen out for cleaning. After cleaning, the fixed frame is inserted into the fixed shell. The set drive component can drive the limit rod to rotate in the opposite direction. Finally, the upper end of the limit rod is inserted into the fixed frame, which can fix the position of the fixed frame, making it convenient to clean the filter screen. The operation is convenient and simple. When it is necessary to disassemble the first and second housings, the first and second housings can be removed using the fixed components, and the reactor body can be removed. When it is necessary to install the whole device, the first and second housings are inserted into the reactor body, and the fixed components can fix the positions of the first and second housings, which facilitates the disassembly and installation of the first and second housings.

[0008] In the above technical solution, the fixing component further includes: Two fixed posts are fixedly installed on the top of the second housing. Each of the two fixed posts has a sliding groove, and a sliding post is slidably installed in each of the two sliding grooves. A tension spring is fixedly installed on each of the two sliding posts. The bottom ends of the two tension springs are fixedly connected to the inner walls of the two sliding grooves, respectively. The lower ends of the two sliding posts pass through the two sliding grooves and extend into the first housing. The lower ends of the two sliding posts are inserted into the first housing. The upper ends of the two sliding posts pass through the two sliding grooves and extend to the outside.

[0009] In this technical solution, when it is necessary to disassemble the first housing and the second housing, firstly, pull the connecting rod upward. The connecting rod drives the two sliding columns to slide upward, and at the same time, both tension springs are stretched. After the two sliding columns are disengaged from the first housing, the first housing and the second housing can be removed, and the reactor body can be removed. When it is necessary to install the whole device, insert the first housing and the second housing into the reactor body, and then release the connecting rod. Under the action of the tension of the two tension springs, the connecting rod and the two sliding columns slide downward. Finally, the two sliding columns are inserted into the first housing, which can fix the position of the first housing and the second housing, making it convenient to disassemble and install the first housing and the second housing.

[0010] In the above technical solution, the driving component further includes: A fixed rod is fixedly installed on a limiting rod. A disc is fixedly installed on the fixed rod. A torsion spring is sleeved on the fixed rod. The two ends of the torsion spring are fixedly connected to the disc and the inner wall of the limiting groove, respectively. One end of the fixed rod passes through the limiting groove and extends to the outside.

[0011] In this technical solution, when the fixed frame needs to be disassembled and cleaned, first rotate the fixed rod forward. The fixed rod drives the disc and the limiting rod to rotate forward, and at the same time, the torsion spring twists. After the limiting rod disengages from the fixed frame, the operator can pull the handle and pull the fixed frame and filter screen out for cleaning. After cleaning, the fixed frame is inserted into the fixed shell, and then the fixed rod is released. Under the torsional force of the torsion spring, the fixed rod, disc, and limiting rod all rotate in the opposite direction. Finally, the upper end of the limiting rod is inserted into the fixed frame, which can fix the position of the fixed frame, making it convenient to clean the filter screen. The operation is convenient and simple.

[0012] In the above technical solution, both the fixing rod and the disc are rotatably connected to the limiting groove.

[0013] In this technical solution, it is ensured that both the fixing rod and the disc can rotate within the limiting groove.

[0014] In the above technical solution, a handle is further fixedly installed on one side of the fixed frame.

[0015] In this technical solution, a handle is provided to facilitate pulling out the fixed frame.

[0016] In the above technical solution, the bottom of the filter screen and the bottom of the fixed frame are located on the same horizontal line, and the thickness of the filter screen is less than the thickness of the fixed frame.

[0017] In this technical solution, it is ensured that dust can remain on top of the filter.

[0018] In the above technical solution, furthermore, the tops of the two sliding columns are fixedly installed with the same connecting rod.

[0019] In this technical solution, it is ensured that when the operator pulls the connecting rod, the two sliding columns can slide simultaneously.

[0020] The beneficial effects of this utility model are: 1. In this series reactor heat dissipation structure, when the fixed frame needs to be disassembled and cleaned, the set drive component can drive the limit rod to rotate in the forward direction. After the limit rod is disengaged from the fixed frame, the operator pulls the fixed frame and filter screen out for cleaning. After cleaning, the fixed frame is inserted into the fixed shell, and the set drive component can drive the limit rod to rotate in the reverse direction. Finally, the upper end of the limit rod is inserted into the fixed frame, which can fix the position of the fixed frame, making it convenient to disassemble and clean the filter screen. The operation is convenient and simple.

[0021] 2. The heat dissipation structure of this series reactor allows for the removal of the first and second housings via a fixing component when disassembly is required, enabling the reactor body to be removed. When the entire device needs to be installed, both the first and second housings are inserted into the reactor body, and the fixing component secures their positions, facilitating disassembly and installation without the need for tools.
