Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency DC isolators, in particular to a radio frequency DC isolator control device. Background Art

[0002] RF DC block is a device used to isolate and block the propagation of RF signals in a circuit or system. Its main function is to effectively isolate the interference between different signals in the RF system, prevent mutual interference and crosstalk between signals, so as to ensure stable transmission and normal operation of the signal;

[0003] RF DC blockers may generate a certain amount of heat during operation, especially when processing high-power RF signals. The degree of heat generation depends on factors such as the design of the DC block, operating frequency, and power. In order to effectively reduce the heating problem, some RF DC block designs will consider heat dissipation structures, such as heat sinks, fans, etc., to help dissipate heat and keep the temperature within a safe range;

[0004] There are many types of RF DC blocks with different sizes. Smaller RF DC blocks may face overheating problems when handling high-power RF signals. However, the small size makes it difficult for the heat sink to play a good heat dissipation effect. To achieve effective heat dissipation, a certain number of heat sinks are required, but the small size limits the possibility of using a large number of heat sinks. Utility Model Content

Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] In order to solve the problem that a relatively small RF DC block is prone to overheating when processing high-power RF signals due to its small size and limited heat dissipation area, the utility model provides the following technical solutions:

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0027] Reference Figures 1 to 5 , is an embodiment of the utility model, which provides a radio frequency DC block control device, such as Figure 1-Figure 2 As shown, the heat dissipation assembly 100 includes a heat dissipation copper tube 101, which is arranged in a spiral shape and spread out along a plane. When a smaller RF isolator can cover its surface, the space occupied by the heat dissipation copper tube 101 only needs to refer to the thickness of the heat dissipation copper tube 101. There is a uniform interval 102 between adjacent heat dissipation copper tubes 101, which increases the heat dissipation efficiency.

[0028] The heat dissipation copper tube 101 is a hollow structure, and has a heat dissipation chamber 100-1. An opening is provided on the heat dissipation copper tube 101, which is conducive to further heat dissipation of the RF isolator. The fan assembly 200 cooperates with the heat dissipation copper tube 101. Under the action of the fan, wind enters the interior of the heat dissipation copper tube 101 through the opening, accelerating heat loss.

[0029] like Figure 3As shown, the heat dissipation copper tube 101 has a side opening 101a on the side and a top opening 101b on the top. Wind will enter the heat dissipation copper tube 101 from the gap 102 between adjacent heat dissipation copper tubes 101 through the side opening 101a. The top opening 101b mainly serves to increase the air circulation in the heat dissipation copper tube 101, effectively promote the heat dissipation, and further improve the heat dissipation efficiency.

[0030] like Figure 3 As shown, the heat dissipation copper tube 101 includes a first heat dissipation area 101c and a second heat dissipation area 101e. The first heat dissipation area 101c is composed of alternately arranged concave surfaces 101c-1 and planes, and a heat dissipation groove 101c-1a is provided on the concave surface 101c-1. The second heat dissipation area 101e is in direct contact with the surface of the RF isolator, and heat is transferred from the second heat dissipation area 101e to the first heat dissipation area 101c. The second heat dissipation area 101e is mainly responsible for transferring heat, while the first heat dissipation area 101c effectively conducts heat through the surface formed by the alternately arranged concave surfaces 101c-1 and the planes, thereby improving the heat dissipation efficiency. By making the first heat dissipation area 101c composed of alternately arranged concave surfaces and planes, and making the second heat dissipation area 101e in direct contact with the surface of the RF isolator, heat can be effectively transferred and conducted, thereby improving the heat dissipation efficiency.

[0031] like Figure 4 , Figure 5 As shown, both sides of the heat dissipation copper tube 101 have flat surfaces, so for some low-power RF isolators, they can be directly installed on the RF isolators without using the fan assembly 200. The generated heat is discharged from the side opening 101a, the top opening 101b, and the first heat dissipation area 101c.

[0032] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete element may be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure described herein that performs the function, and is not only structurally equivalent but also an equivalent structure.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0033] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment may not be described (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention).

[0034] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
