Description

Technical Field

[0001] The utility model relates to the technical field of microwave, in particular to a stacked structure of microwave components. Background Technique

[0002] At present, the main structure in the industry is to use a scheme of milling cavities and installing cover plates on both the front and back sides, so that the two printed circuit boards share a bottom surface. During use, it is necessary to make concessions for the screws on the printed circuit boards on both the front and back sides, resulting in the need to consider screw interference problems during hardware design, with many limitations; and because the printed circuit board with cavities milled on both sides cannot be placed at the bottom of the radio frequency microwave module, the heat dissipation of the devices with high heat consumption on the printed circuit board is poor, affecting the module performance. Therefore, a microwave radio frequency module structure that can reduce design limitations and ensure heat dissipation is needed.

[0003] Under the current industry trends of high power, multi-function and miniaturization, the traditional structure is increasingly unable to meet the requirements of installation space, heat dissipation and weight. Because the two printed circuit boards on the front and back share a bottom surface, it is necessary to consider avoiding the installation and avoidance of screws on both sides during the design of the printed circuit board, and concessions have to be made in the module performance indicators. At the same time, as the device power gradually increases, and the whole machine uses water cooling or air cooling at the bottom of the module, the traditional structure can no longer meet the heat dissipation requirements of the microwave radio frequency module and reduce the reliability of the microwave radio frequency module. Content of the Utility Model

[0004] To overcome the deficiencies of the prior art, the utility model provides a stacked structure of microwave components, which solves the shortcomings of the prior art such as insufficient installation space for module components, poor heat dissipation of devices, and high module weight.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A stacked structure of microwave components, including a top module, a middle module, and a bottom heat dissipation module arranged in sequence from top to bottom. The bottom heat dissipation module includes a cavity, and a limiting step is provided on the inner side wall of the cavity.

[0007] As a preferred technical solution, the position of the limiting step in the height direction is adjustable.

[0008] As a preferred technical solution, the top module includes a first circuit board, the middle module includes a second circuit board, a partition, and a third circuit board, the bottom heat dissipation module includes a fourth circuit board, and the first circuit board, the second circuit board, the partition, the third circuit board, the fourth circuit board, and the cavity are arranged in sequence from top to bottom.

[0009] As a preferred technical solution, it includes a cover plate arranged above the first circuit board.

[0010] As a preferred technical solution, the cover plate and the first circuit board are installed by screw mounting or welding.

[0011] As a preferred technical solution, the cover plate is provided with first screw holes, and the first circuit board is provided with second screw holes, and the first screw holes cooperate with the second screw holes.

[0012] As a preferred technical solution, the second circuit board is installed on one side of the partition by screw mounting or welding, and the third circuit board is installed on the other side of the partition by screw mounting or welding.

[0013] As a preferred technical solution, the fourth circuit board and the cavity are installed by screw mounting or welding.

[0015] As a preferred technical solution, the cover plate is provided with first screw holes, and the cavity is provided with sixth screw holes.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) Originally, two cover plates were required for the structural parts, and both sides of the cavity needed to be processed, resulting in a relatively high cost. After replacing with the new structure, only one side of the cavity needs to be processed, reducing the processing cost of the structural parts.

[0018] (2) The traditional cavity can only install two circuit boards. After using the new structure, four circuit boards can be installed, which can reduce the external dimensions and weight of the module, facilitating the trend of miniaturization and light weight.

[0019] (3) The current structure can directly place the device at the bottom of the module, enabling it to directly dissipate heat to the whole machine's cold plate, enhancing its heat dissipation performance. Description of the Drawings

[0049] Such as Figures 1 to 2As shown in the figure, as a further optimization of Embodiment 1, on the basis of Embodiment 1, this embodiment further includes the following technical features:

[0050] This utility model mainly divides the microwave radio frequency module into three parts:

[0051] The first part is the top module composed of a cover plate 1 and a first circuit board 2. The first circuit board 2 is fastened to the cover plate 1, and the fastening method can be fastening by screw holes (the second screw hole 201 and the first screw hole 101) or welding;

[0052] The second part is the middle module composed of a partition 4, a second circuit board 3 and a third circuit board 5. Among them, the second circuit board 3 and the third circuit board 5 are respectively fixed on both sides of the partition 4 by screws or welding. The second circuit board 3 and the partition 4 can be fastened on the partition 4 through through holes 301 and the third screw hole 401.

The cavity 7 is mainly composed of a limit step 701, a fifth screw hole 702 (partition installation screw hole) and a sixth screw hole 703 (cover plate installation screw hole).

[0054] Among them, the four circuit boards are connected through connectors, and the structural parts are installed by screws.

[0055] Usage method:

[0056] 1. Install the first circuit board 2 to the cover plate 1 by screws or welding to form the top module;
