Description

Technical Field

[0001] This utility model relates to the field of circulator technology, and in particular to a cooled circulator. Background Technology

[0002] A circulator is a device in a microwave radio frequency system that uses unidirectional electromagnetic wave transmission. It is typically used between a microwave source and a load to prevent interference from the load direction, thus ensuring stable operation of the microwave source. With increasing market demand, the power requirements for circulators are becoming increasingly stringent, with some products requiring circulators with power up to 10kW. However, excessively high power generates a large amount of heat during operation, which accumulates inside the circulator and cannot be released. Prolonged operation can negatively impact the circulator's performance, and continuous operation may even lead to burnout.

[0003] Therefore, there is an urgent need for a cooling circulator to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a cooling circulator that can solve the problem that the circulator generates a large amount of heat that cannot be released during operation, which affects the performance of the circulator or even causes it to burn out.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cooling circulator, comprising:

[0007] The housing and a central conductor, two ferrites, two uniform magnetic sheets, two cooling components, and two magnetic sheets are placed inside the housing. The two ferrites, two uniform magnetic sheets, two cooling components, and two magnetic sheets are respectively placed on both sides of the central conductor from near to far.

[0008] The cooling assembly includes a cooling element and two throttle valves. The cooling element has a continuous curved groove inside, and the curved groove includes an inlet and an outlet. The inlet and the outlet are both located on the side wall of the cooling element. One of the throttle valves is located at the inlet, and the other throttle valve is located at the outlet.

[0009] As a preferred technical solution for a cooling annular device, the path of the curved groove is a continuous S-shaped path.

[0010] As a preferred technical solution for a cooling circulator, the cooling component includes a main body and a sealing plate. The main body has a first receiving groove on the side facing the ferrite. The curved groove is placed in the first receiving groove. The inlet and the outlet are both located on the side wall of the first receiving groove. The sealing plate is used to block the first receiving groove.

[0011] As a preferred technical solution for the cooling annulus, the side of the sealing plate is welded to the inner wall of the first receiving groove.

[0012] As a preferred technical solution for the cooling circulator, the first receiving groove is a stepped groove, which includes a first groove and a second groove that are connected. The sealing plate is placed in the first groove, the height of the first groove is the same as the thickness of the sealing plate, and the curved groove is placed in the second groove.

[0013] As a preferred technical solution for the cooling circulator, the cooling circulator further includes two temperature compensation plate assemblies, which are respectively placed on the side of the two magnet plates away from the cooling element, and both temperature compensation plate assemblies are placed inside the housing.

[0014] As a preferred technical solution for the cooling circulator, the main body has a second receiving groove on the side facing the magnet sheet, and both the magnet sheet and the temperature compensation plate assembly are placed in the second receiving groove.

[0015] As a preferred technical solution for the cooling circulator, the cooling circulator further includes two shims, which are respectively placed on the side of the two temperature compensation plate assemblies away from the magnet plate.

[0016] As a preferred technical solution for a cooling circulator, the housing includes an enclosure and two cover plates. The enclosure consists of four side plates connected end to end, and the two cover plates respectively block the two openings of the enclosure.

[0017] As a preferred technical solution for a cooling circulator, the surrounding member is provided with a clearance hole, and the throttle valve is located in the clearance hole.

[0018] Compared with the prior art, the cooling ring device provided by this utility model has the following technical advantages:

[0019] 1. By setting up a cooling component and making the cooling component fit in close contact with the ferrite, coolant can be supplied to the inlet when the cooling circulator is working. The coolant flows along the curved groove to the outlet. During the flow, the coolant absorbs the heat generated by the ferrite, which quickly cools the ferrite and prevents a large amount of heat from accumulating inside the cooling circulator. This ensures the performance of the cooling circulator and prevents it from burning out during operation.

[0020] 2. By placing two ferrites, two uniform magnetic plates, two cooling components, and two magnetic plates on both sides of the central conductor from near to far, the internal components of the cooling circulator are designed in a symmetrical layout. This ensures that the heat generated on both sides of the central conductor of the cooling circulator is balanced, preventing the heat generated by the cooling circulator from concentrating in one location and improving the safety of the cooling circulator.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figures 1 to 5 As shown, this embodiment provides a cooled circulator, which includes a housing 1 and a central conductor 2, two ferrites 3, two uniform magnetic plates 4, two cooling components 5, and two magnetic plates 6 disposed inside the housing 1. The two ferrites 3, two uniform magnetic plates 4, two cooling components 5, and two magnetic plates 6 are positioned from near to far on both sides of the central conductor 2. The central conductor 2 is used for signal transmission, the magnetic plates 6 are used to provide an external bias magnetic field, and the uniform magnetic plates 4 are used to make the external bias magnetic field uniform. The ferrites 3 provide a rotating magnetic field. The ferrites 3 generate the most heat during the operation of the cooled circulator. The cooling components 5 are in close contact with the ferrites 3, enabling rapid cooling of the ferrites 3 during operation and preventing the circulator from generating excessive heat. In this embodiment, the functions of the central conductor 2, uniform magnetic plates 4, ferrites 3, and magnetic plates 6 are common knowledge in the field of circulators and will not be elaborated further.

[0037] The cooling assembly 5 includes a cooling element 51 and two throttle valves 52. The cooling element 51 has a continuous curved groove 5112 inside, with an inlet and an outlet, both located on the side wall of the cooling element 51. One throttle valve 52 is located at the inlet, and the other at the outlet. When the cooling circulator is working, coolant is supplied to the inlet, flowing through the curved groove 5112 to the outlet. During this flow, the coolant absorbs the heat generated by the ferrite 3, enabling rapid cooling of the ferrite 3 during operation. This prevents excessive heat buildup inside the circulator, ensuring its performance and preventing burn-out. One throttle valve 52 is located at the inlet, and the other at the outlet. When the circulator is working, the operator opens both throttle valves 52 to allow coolant to flow within the curved groove 5112. When the circulator is not in operation, both throttle valves 52 are closed.

[0038] The cooling circulator provided in this embodiment, by setting up a cooling component 5 and making the cooling component 5 fit in contact with the ferrite 3, can deliver coolant to the inlet when the cooling circulator is working. The coolant flows along the curved groove 5112 to the outlet. During the flow, the coolant absorbs the heat generated by the ferrite 3, rapidly cooling the ferrite 3 and preventing a large amount of heat from accumulating inside the cooling circulator, thus ensuring the performance of the cooling circulator and preventing it from burning out during operation. By placing the two ferrites 3, two uniform magnetic plates 4, two cooling components 5, and two magnetic plates 6 on both sides of the central conductor 2 from near to far, that is, designing the internal components of the cooling circulator in a symmetrical layout, it can ensure that the heat generated on both sides of the central conductor 2 of the cooling circulator is balanced, avoiding the heat generated by the cooling circulator from concentrating in one place, thus improving the safety of the cooling circulator.

[0039] For coolant, glycerin-based coolant, ethylene glycol-based coolant, and propylene glycol-based coolant can be used. There are no specific restrictions on the type of coolant.

[0040] As a preferred option, such as Figure 1 , Figure 4 and Figure 5As shown, the curved groove 5112 follows an S-shaped path, allowing it to cover a larger area within the cooling element 51. When the coolant flows along the curved groove 5112, more heat from the ferrite 3 is absorbed, improving the cooling effect of the cooling assembly 5 on the ferrite 3 and thus enhancing the safety of the cooling circulator. Furthermore, the width of the curved groove 5112 is 3cm-5cm, and its depth is 2cm-3cm. Excessive width and depth of the curved groove 5112 will affect the coolant flow rate, hindering balanced cooling of all areas of the ferrite 3 and consequently impacting its performance. The specific width and depth of the curved groove 5112 should be determined based on the dimensions of the ferrite 3 and the specifications of the cooling circulator; no specific limitations are imposed here.

[0041] For example, the cooling component 51 includes a main body 511 and a sealing plate 512. The main body 511 has a first receiving groove 5111 on the side facing the ferrite 3. A curved groove 5112 is placed inside the first receiving groove 5111, and the inlet and outlet of the curved groove 5112 are both located on the side wall of the first receiving groove 5111. The sealing plate 512 is used to seal the first receiving groove 512. This makes it easier to process and assemble the cooling component 51, and after the sealing plate 512 seals the first receiving groove 512, it can ensure the flow of coolant in the first receiving groove 5111.

[0042] Furthermore, the side of the sealing plate 512 is welded to the inner wall of the first receiving groove 5111 so that the sealing plate 512 can seal the first receiving groove 5111. By welding the sealing plate 512 to seal the first receiving groove 5111, the overall structural stability of the cooling component 51 can be improved.

[0043] Preferably, the first receiving groove 5111 is a stepped groove, which includes a first groove and a second groove that are connected. The sealing plate 512 is placed in the first groove, and the height of the first groove is the same as the thickness of the sealing plate 512. The curved groove 5112 is placed in the second groove. This makes it easier to assemble the sealing plate 512. After assembly, the sealing plate 512 is flush with the end face of the cooling component 51, avoiding local compression of the ferrite 3 inside the cooling annulus and affecting the performance of the ferrite 3.

[0044] In this embodiment, as Figure 1As shown, the cooling circulator also includes two temperature compensation assemblies 7, which are respectively placed on the side of the two magnet plates 6 away from the cooling element 51, and both temperature compensation assemblies 7 are housed within the housing 1. When the cooling circulator is working, its internal temperature will change, which may cause changes in the parameters of the cooling circulator. The temperature compensation assemblies 7 help to maintain the temperature stability of the cooling circulator, thereby ensuring the stability of its parameters and further improving the stability of the cooling circulator's operation. Specifically, the temperature compensation assembly 7 includes two mutually fitted temperature compensation plates, namely a first temperature compensation plate 71 and a second temperature compensation plate 72.

[0045] As a preferred option, such as Figure 1 and Figure 6 As shown, the main body 511 has a second receiving groove 5113 on the side facing the magnet plate 6, wherein both the magnet plate 6 and the temperature compensation plate assembly 7 are placed in the second receiving groove 5113. The second receiving groove 5113 is provided to position the magnet plate 6 and the temperature compensation plate assembly 7, making it easier to assemble the cooling ring device.

[0046] Preferably, the cooling annulus further includes two shims 8, which are respectively placed on the side of the two temperature compensation plate assemblies 7 away from the magnet plate 6. Specifically, the two shims 8 abut against the top and bottom surfaces of the housing 1, respectively. The arrangement of the shims 8 can prevent multiple components inside the housing 1 from shaking and improve the stability of the layout of multiple components inside the housing 1.

[0047] Exemplarily, the housing 1 includes a surround 11 and two cover plates 12. The surround 11 is composed of four side plates 111 connected end to end, which facilitates the assembly of the surround 11. Simultaneously, the four side plates 111 improve the performance of the rotating magnetic field and the external deflection magnetic field, preventing leakage of these fields. The cover plates 12 respectively block two openings of the surround 11, protecting the components placed inside. Furthermore, the surround 11 includes a clearance hole, in which the throttle valve 52 is located. Specifically, the clearance hole is disposed on the side plate 111 opposite to the throttle valve 52, making the structural design of the surround 11 more rational.

[0048] Furthermore, the cover plate 12 is connected to the main body 511 by fasteners, while the side plate 111 is connected to the side wall of the main body 511 by fasteners. In this embodiment, bolts are selected as the fasteners.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
