Description

Technical Field

[0001] The present invention relates to the technical field of piezoelectric ceramic controllers, and in particular to a piezoelectric ceramic controller. Background Art

[0002] Piezoelectric controllers, as high-precision control devices, are widely used in various high-tech fields. Traditional piezoelectric controllers typically consist of stacked layers of printed circuit boards (PCBs), a design that enables complex functionality. These layers are connected by connectors to achieve coordinated control of the entire system. However, this design presents several technical challenges in practical application.

[0003] First, heat dissipation is a key challenge in multilayer piezoelectric ceramic controllers. Under normal circumstances, fans are typically used for cooling to effectively dissipate heat. However, in some special environments, such as a vacuum, fans are unable to circulate air, preventing the effective removal of heat. In these cases, heat is trapped inside the chassis, adversely affecting electrical components and, in severe cases, causing overheating or even damage to the device.

[0004] Secondly, maintenance issues significantly impact the practical application of multilayer piezoelectric ceramic controllers. For single-layer piezoelectric ceramic controllers, maintenance is relatively simple, requiring only opening the chassis. However, when controllers are designed with multilayer stacked structures, disassembly and assembly become significantly more difficult due to the entanglement of various leads and connectors. Repairs often require disassembly of the entire device, which is not only time-consuming and labor-intensive but can also lead to increased downtime, impacting its efficiency and reliability.

[0005] In summary, heat dissipation and maintenance issues are particularly prominent in the application of multilayer piezoelectric ceramic controllers. These technical challenges need to be addressed urgently to improve the performance of the equipment and facilitate maintenance. Summary of the Invention

[0057] Implementation Method 11: Combination Figure 1-8 This embodiment further clearly and completely describes the technical solution provided above through specific examples, specifically:

[0058] The purpose of this embodiment is to provide a piezoelectric ceramic controller chassis that can be used in special environments. During use, the heating surfaces of all heat-generating electronic components are in direct contact with the chassis, and all heat is transferred from the chassis in the form of conduction and radiation. The multi-layer PCB boards are installed in their own independent sub-chassis, and each chassis can be removed separately. This utility model is achieved by the following methods:

[0059] Install a heat sink on the heating surface of the heating electrical component. The heat sink is in direct contact with or integrated with the chassis shell, so that the generated heat can be transferred out through the chassis shell.

[0060] The heating elements on the side can directly dissipate heat by contacting the heat dissipation surface with the panel, or heat dissipation plates of different specifications can be installed to conduct heat to the panel. The heating elements on the inside can be equipped with a heat dissipation plate integrated with the chassis between the heat dissipation surface and the PCB board for heat conduction.

[0061] Each layer of PCB is installed in its own independent sub-chassis, which are connected by screws, and the boards are connected in series using inter-board connectors.

[0062] like Figure 1 As shown, a schematic diagram of the overall piezoelectric ceramic controller chassis that can be used in special environments includes an upper panel 1, an upper sub-box 2, a lower sub-box 3 and a lower panel 4. The upper panel 1, the upper sub-box 2, the lower sub-box 3 and the lower panel 4 are connected in sequence from top to bottom by screws to form a closed box, and each box can be disassembled and installed separately.

[0063] like Figure 2-4 As shown, a schematic diagram of the connection between the upper panel and the upper sub-box includes an upper heat sink 101, an upper heat sink 202, an upper panel edge 103, a matching heat sink 201, a matching heat sink 202, an upper sub-box edge 203, a fixing bar 204, and an upper inter-board connector 205. The upper inter-board connector 205 is mounted on the PCB and can transmit signals to the lower layer.

[0064] A PCB is installed in the upper housing 2. When the main heat generating component of the installed PCB is a chip, a heat sink that meets the chip specifications can be processed and matched with the chip. The heat sink is installed to a position connected to the heat dissipation surface of the chip. The heat sink 1 201 and the heat sink 2 202 are respectively installed on the fixing bar 204 on the other side of the PCB by multiple screws. The heat sink can have various specifications and shapes. The heat sink 1 201 and the heat sink 2 202 are not the only types that can be installed.

[0065] The upper sub-box 2 is connected to the upper panel 1 with screws. The positioning screws pass through the through holes on the upper panel edge 103 and the upper sub-box edge 203 respectively to complete the positioning of the two. The upper sub-box 2 can be disassembled and installed separately.

[0066] like Figure 5-7 As shown, the lower sub-box 3 includes a processed heat dissipation plate 301, a heating element 302, a non-heating surface 3021 of the element, a heating surface 3022 of the element, a lower sub-box side 303, a non-heating element 304, and a lower inter-board connector 305. The lower board connector 305 is mounted on the PCB board and connected to the upper board connector 205. Signals can be transmitted between the two, and disassembly and assembly can be directly plugged in and out.

[0067] The lower sub-box 3 is installed with a PCB board. To maintain the normal function of the PCB board, a heating element 302 and a non-heating element 304 are provided. The non-heating element 304 is a conventional electrical component and can be directly installed on the PCB board. The heating element 302 can be divided into two sides: a non-heating surface 3021 and a heating surface 3022. During installation, the heating surface 3022 is installed on the PCB board through the processed heat sink 301, so that heat can be directly transferred to the processed heat sink 301.

[0068] The heat dissipation plate 301 is processed integrally with the box body, and the processing position is determined according to the position of the heating element 302 on the PCB board. The processing area and position can be determined according to the position of the heating element 302;

[0069] The lower sub-box body 3 is connected to the upper sub-box body side 203 by screws through the lower sub-box body side 303 to complete the positioning of the two, and the lower sub-box body 3 can be disassembled and installed separately;

[0070] like Figure 8 As shown, the lower panel 4 includes a heat dissipation portion 401, a non-heat dissipation portion 402, and a lower panel edge 403;

[0071] The heat dissipation portion 401 and the non-heat dissipation portion 402 together constitute the lower panel 4. The area and position of the two are determined according to the position of the electrical components on the PCB board. The non-heat dissipation portion 402 is a conventional panel, and the heat dissipation portion 401 is a thickened panel, which can be in direct contact with the components that need to be cooled, thereby achieving a heat dissipation effect. The lower panel edge 403 is used to fix the lower panel 4 on the lower sub-box body 3 by screws.

[0072] Working principle: In some environments where fan cooling is not possible, the piezoelectric ceramic controller can transfer the generated heat to the outer surface of the chassis through various heat dissipation plates and panels, through direct contact with the heating surface 3022 of the heating element 302, thereby cooling the inside of the chassis and ensuring the normal operation of the electrical components. At the same time, each sub-chassis and its internal PCB board are installed independently, and each sub-chassis is an independent entity. The sub-chassis are connected by plate connectors to achieve series control, ensuring normal use while having the function of convenient disassembly and maintenance.

[0073] The utility model works according to the above method and has the following beneficial effects:

[0074] The heating surfaces of the heating electrical components are in direct contact with the heat sink, which is either in direct contact with the chassis or is part of the chassis. The heat generated by the heating electrical components is transferred to the chassis through the heat sink and then radiated out, thus achieving cooling inside the chassis without the need for a fan.

[0075] The heat sink can be flexibly adjusted according to the structure and position of the PCB board and the electrical components on it. The outer heat sink can be in direct contact with the chassis, and the inner heat sink can be processed to be integrated with the chassis, meeting the structural requirements of all types of controllers.

[0076] Each layer of PCB board can be installed separately in the sub-chassis of each layer. The sub-chassis of each layer can be disassembled and assembled independently, and the boards are connected through board connectors to complete the series connection of signals.

[0077] The above further describes in detail the technical solution provided by the present invention through several specific implementation methods in order to highlight the advantages and benefits of the technical solution provided by the present invention. However, the several specific implementation methods described above are not intended to limit the present invention. Any reasonable modification and improvement of the present invention, combination of implementation methods and equivalent replacement based on the spirit and principles of the present invention should be included in the scope of protection of the present invention.
