[0002] In numerous fields such as industrial production, laboratory research, and environmental monitoring, paperless recorders play a crucial role due to their digital data recording capabilities based on modern computer and electronic information technologies. Their principle involves using sensors to convert physical quantities such as temperature, pressure, and flow rate into electrical signals. These electrical signals are then processed into digital signals by an internal analog-to-digital converter, enabling data acquisition, storage, and display. However, the panels currently installed in paperless recorders on the market have significant drawbacks. Firstly, the panel layout is not optimal; secondly, the spacing between panels is too tight, resulting in poor heat dissipation and slow cooling. Over time, this severely impacts the lifespan of the paperless recorder, making it difficult to meet the requirements for stable and long-term operation. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figure 1 As shown, this utility model provides a partitioned heat dissipation chassis for a paperless recorder. A paperless recorder typically consists of a motherboard, input port, memory, display screen, communication interface, converter, circuit, channel board, power supply and button components. It has functions such as parameter data acquisition, processing and display. Its principle belongs to the prior art and will not be described in detail here.

[0035] In existing technologies, the internal structure of paperless recorders is poorly designed, resulting in overly compact circuit boards or panels, leading to poor heat dissipation and affecting normal operation. This invention optimizes the internal structure of the chassis, rationally separating key components and effectively increasing the spacing between circuit boards or panels to create better airflow channels. This significantly improves heat dissipation efficiency, ensuring the paperless recorder maintains a suitable temperature range during long-term operation and fully leverages its performance advantages.

[0036] Specifically, such as Figure 2 and 3 As shown, the chassis includes: display frame 100, plate 200, crossbeam 300, guide rail 400 and cover plate 500. The combination of the above sides forms a complete chassis structure. The components cooperate with each other, the layout is compact, and the space can be fully utilized to improve the space utilization rate of the chassis.

[0037] like Figure 2 As shown, a connecting frame 11 is provided on one end face of the display frame 100. The connecting frame 11 is formed by an integrally molded connecting plate, which can enhance the structural strength and stability of the connecting frame 11 and ensure that the connection between the display frame 100 and other components is more firm and reliable.

[0038] like Figure 2 As shown, a panel 200 is provided on the display frame 100. The panel 200 consists of a top plate 21, a bottom plate 22, and two side plates 23. The top plate 21, bottom plate 22, and side plates 23 are all assembled and connected to the connecting frame 11, thus forming the overall appearance structure of the chassis. Multiple rows of heat dissipation holes 24 are provided on the top plate 21 and bottom plate 22. These holes dissipate heat generated by the internal components of the chassis, improving the service life of the device.

[0039] In addition, such as Figure 4 and 5As shown, crossbeams 300 are provided on both side panels 23. Two sets of crossbeams 300 are arranged in pairs, facing each other vertically. Each crossbeam 300 has multiple protrusions 31 that divide it into multiple mounting areas 32, each independently configured. Since multiple circuit boards or panels with different performance parameters need to be installed inside the chassis, one mounting area 32 located on the side of the crossbeam 300 constitutes the first area 321, which is the high-power area. The leftmost or rightmost mounting area 32 can be selected according to actual needs. The remaining mounting areas 32 constitute the second area 322, which is the low-power area with lower power output than the first area 321. For example, the core card panel 60 is installed in the first area 321, while something like a memory is installed in the second area 322. Typically, the core card needs to handle more computational tasks and control logic, while the memory's main task is data storage, and its power consumption is relatively low. This will not be discussed further. By separating the high-power and low-power areas, the low-power area is prevented from being disturbed by the heat dissipation of the high-power area, ensuring that the components in the low-power area can operate in a relatively stable temperature environment.

[0040] like Figure 3 As shown, the panel assembled in the first area 321 can also be attached to the side panel 23 to perform the function of heat transfer. Relying on the large area of ​​contact, its heat dissipation effect is improved.

[0041] In each of the aforementioned installation areas 32, that is, on the crossbeam 300, a guide rail 400 is provided. The guide rail 400 has a slot 41 for fitting with a circuit board or panel, and both ends of the guide rail 400 are respectively engaged with a crossbeam 300.

[0042] Specifically, such as Figure 5 and 6 As shown, each mounting area 32 is provided with a positioning hole 33 and a first mounting hole 34 adjacent to the positioning hole 33. The guide rail 400 has a positioning post 44 on one end face opposite to its slot 41, which is adapted to the positioning hole 33. The guide rail 400 also has a second mounting hole 43 corresponding to the first mounting hole 34. During installation of the guide rail 400, the positioning post 44 is first inserted into the positioning hole 33 to pre-position the guide rail 400 and the crossbeam 300. Then, the nut 52 is fitted into either the first mounting hole 34 or the second mounting hole 43 to connect them, thus satisfying a certain degree of quick-release requirements. Simultaneously, the crossbeam 300 and guide rail 400 facilitate the fixing and support of the circuit board or panel, allowing it to be installed at a predetermined position and angle while maintaining a certain distance, which is beneficial for heat dissipation.

[0043] Among them, such as Figure 6As shown, flared sections 42 are provided at the insertion ports at both ends of the guide rail 400 slot 41, and the bottom surface of the flared section is inclined. The flared section and the inclined bottom surface guide the insertion of the circuit board or panel, unlike the setting of a vertical section, which requires the circuit board or panel to be more precisely aligned with the position of the insertion port before it can be inserted and assembled. This solves the problem of cumbersome assembly and improves installation efficiency.

[0044] However, the guide rail 400 is supported on the crossbeam 300 and is not flush with the bottom of the crossbeam 300, that is, there is a height difference, which gives the bottom of the guide rail 400 a certain space for airflow to improve the rapid dissipation of heat.

[0045] The top plate 21 and bottom plate 22 are fitted and abut against the crossbeam 300, making the overall structure relatively compact. The large-area fit also facilitates heat transfer. Furthermore, the positions of each row of heat dissipation holes 24 correspond to the intervals between the two guide rails 400 or are staggered from the guide rails 400, allowing the heat dissipation holes 24 to directly correspond to the circuit board or panel, enabling faster airflow instead of being directly blocked by the guide rails 400, thus increasing the airflow path.

[0046] like Figure 7 As shown, a cover plate 500 is also provided on a crossbeam 300 and connected by fasteners, such as nuts 52. The assembly of the cover plate 500 makes the chassis a whole. When the circuit board or panel is assembled into the slot 41, the cover plate 500 is assembled with the crossbeam 300. At the same time, insertion ends 51 are provided opposite to each other on the two end faces of the cover plate 500. The top of the insertion end 51 is provided with a pressing bevel 511. When the pressing bevel 511 is inserted and contacts the circuit board or panel, it can smoothly restrict the circuit board or panel between the two insertion ends 51, improve the stability of the circuit board or panel, or in other words, separate the distance between the two circuit boards or panels.

[0047] In addition, the display frame 100, plate 200, crossbeam 300, guide rail 400 and cover plate 500 are all aluminum alloy components, and they are made of 6063 series aluminum alloy. This series of aluminum alloy has a high thermal conductivity, which can effectively transfer heat to the surface.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
