Description

Technical Field

[0001] This utility model belongs to the technical field of RFID electronic tag readers, and specifically relates to an RFID electronic tag reader that can improve heat dissipation. Background Technology

[0002] An RFID electronic tag reader, also known as an RFID reader-writer or RFID reader, is a device used to read and write information from RFID electronic tags. It uses radio frequency technology to exchange data with the electronic tags.

[0003] Most existing RFID electronic tag readers use heat sinks and open heat dissipation channels for heat dissipation. If the ambient humidity is high, the humidity in the air will enter the casing through the heat dissipation channels, which can easily damage the internal components. Moreover, since there are many types of components in the reader, and different components generate different amounts of heat, when they are mixed and installed in one space, the overall temperature of the reader can easily become high, causing other components to be in a high-temperature environment and affecting the stability of operation.

[0004] Therefore, an RFID electronic tag reader with improved heat dissipation is proposed. Summary of the Invention

[0005] This invention provides an RFID electronic tag reader with improved heat dissipation, which aims to solve the problems mentioned above.

[0006] This utility model provides an RFID electronic tag reader with improved heat dissipation, including a component-separating heat insulation assembly. The component-separating heat insulation assembly includes: a cross-shaped heat insulation plate; a ridge integrally formed on the top of the cross-shaped heat insulation plate; a slot and a wire-passing hole on the outer wall of the cross-shaped heat insulation plate, the slot being located on one side of the wire-passing hole; a first docking hole respectively formed on the top and bottom of the cross-shaped heat insulation plate; an upper heat dissipation assembly located above the cross-shaped heat insulation plate; and a lower heat dissipation assembly located below the cross-shaped heat insulation plate. The upper heat dissipation assembly includes: four upper shells located above the cross-shaped heat insulation plate; a first retaining strip integrally formed on the bottom of the inner part of the upper shell; and heat dissipation fins integrally formed on the outer wall of the upper shell; and a second docking hole penetrating through the top of the upper shell. The lower heat dissipation assembly includes: four lower shells located below the cross-shaped heat insulation plate; a second retaining strip integrally formed on the top of the lower shell; and a third docking hole at the bottom of the lower shell.

[0007] Furthermore, the lower heat dissipation assembly also includes: a flow guide shroud and a flow guide plate fixed to the bottom of the lower shell plate by bolts, the flow guide shroud being located on one side of the flow guide plate and connected to it, and a fan being provided inside the flow guide shroud.

[0008] Furthermore, the outer sidewalls of both the first and second card strips are matched and fitted with the inner sidewall of the card slot, and both the first and second card strips are slidably connected to the card slot.

[0009] By adopting the above technical solution, it is easy for card strip one and card strip two to connect with the card slot.

[0010] Furthermore, the upper shell and the cross-shaped heat insulation plate are fixed together by screws passing through the second docking hole and screwing into the first docking hole, and the lower shell plate and the cross-shaped heat insulation plate are fixed together by screws passing through the third docking hole and screwing into the first docking hole;

[0011] By adopting the above technical solution, the upper shell and lower shell plate can be connected and fixed to the cross-shaped heat insulation plate.

[0012] Furthermore, the upper shell and the lower shell plate are fixed to the cross-shaped heat insulation plate and are in a tight docking state, and the upper shell is composed of three panels that are perpendicular to each other;

[0013] By adopting the above technical solution, the upper shell, lower shell plate and cross heat insulation plate are connected to form a sealed environment, thereby preventing the entry of external air and moisture, and preventing water vapor in the air from entering the interior of the RFID electronic tag reader, thus preventing damage to internal components. The upper shell is composed of three mutually perpendicular panels, which can form a frame structure, thereby forming a sealed space after assembly.

[0014] Furthermore, a total of seven guide vanes are provided, and the seven guide vanes are arranged in a divergent pattern on the outside of the guide shield;

[0015] By adopting the above technical solution, the airflow can be guided by the deflector, thereby accelerating the airflow rate at the bottom of the lower shell and improving the heat dissipation effect.

[0016] Furthermore, an interface is provided on one side of the outer wall of one of the upper housings;

[0017] By adopting the above technical solution, it is convenient to carry out external wiring operations.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention combines an upper shell, a lower shell plate, and a cross-shaped heat insulation plate. By utilizing the heat insulation capacity of the cross-shaped heat insulation plate and the heat conduction capacity of the upper and lower shell plates, the RFID electronic tag reader can form four sealed and independent heat dissipation spaces. On the one hand, this avoids mixing internal components in one space, allowing the heat generated by the internal components of the RFID electronic tag reader to be dispersed and dissipated separately. This can effectively dissipate heat from high-heat-generating components and better protect heat-sensitive components. On the other hand, it prevents humidity from the air from entering the reader and damaging the internal components.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1-5 This utility model embodiment proposes an RFID electronic tag reader with improved heat dissipation, including a cross-shaped heat insulation plate 11 in the component separating heat insulation assembly 1. The top and bottom of the cross-shaped heat insulation plate 11 are integrally formed with ridge protrusions 12, and the outer side wall of the cross-shaped heat insulation plate 11 is provided with a slot 13 and a wire hole 14. The slot 13 is located on one side of the wire hole 14. A through docking hole 15 is provided at the top of the cross-shaped heat insulation plate 11 near the outer side of the ridge protrusion 12. Four upper shells 21 of the upper heat dissipation assembly 2 are provided above the cross-shaped heat insulation plate 11. One of the upper housings 21 has an interface on one side of its outer wall for easy external wiring. All four upper housings 21 have integrally formed retaining strips 22 on their inner tops, and all four upper housings 21 have integrally formed heat dissipation fins 23 on their outer side walls. The top of each upper housing 21 has a through-hole 24. Four lower housing plates 31 of the lower heat dissipation assembly 3 are located below the cross-shaped heat insulation plate 11. The upper housings 21 and lower housing plates 31 are tightly joined after being fixed to the cross-shaped heat insulation plate 11, thus ensuring a tight connection between the upper housings 21, lower housing plates 31, and the cross-shaped heat insulation plate 11. After the hot plates 11 are joined, a sealed environment is formed, preventing external air and moisture from entering and avoiding moisture in the air from entering the interior of the RFID electronic tag reader, thus preventing damage to internal components. The upper shell 21 is composed of three mutually perpendicular panels, which can form a frame-like structure, thus forming a sealed space after assembly. The top of each of the four lower shell plates 31 is integrally formed with a second locking strip 32. The outer walls of the first locking strip 22 and the second locking strip 32 are matched and fitted with the inner wall of the slot 13, and the first locking strip 22 and the second locking strip 32 are slidably connected to the slot 13. To facilitate the docking of the first and second clips 22 and the slot 13, the top of the lower shell plate 31 is provided with a docking hole 33 near the second clip 32. The upper shell 21 and the cross heat insulation plate 11 are fixed by screws passing through the docking hole 24 and screwing into the docking hole 15. The lower shell plate 31 and the cross heat insulation plate 11 are fixed by screws passing through the docking hole 33 and docking hole 15. This allows the upper shell 21 and the lower shell plate 31 to be docked and fixed with the cross heat insulation plate 11. The upper shell 21, the lower shell plate 31 and the heat dissipation fins 23 are all made of aluminum alloy.

[0030] The specific implementation method is as follows: In use, the components that generate a lot of heat during operation are separated and installed on the top of the four lower shell plates 31 respectively. The second clip 32 on the lower shell plate 31 is inserted into the slot 13 on the cross heat insulation plate 11 and fixed with screws. The components are connected by passing the wire harness through the wire hole 14. After the lower shell plate 31 and the cross heat insulation plate 11 are connected, the first clip 22 on the upper shell 21 is inserted into the slot 13 on the cross heat insulation plate 11 and fixed with screws. After the upper shell 21, lower shell plate 31 and cross heat insulation plate 11 are combined and connected, a sealed environment is formed. Due to the barrier of the cross heat insulation plate 11 on the adjacent upper shell 21 and adjacent lower shell plate 31, and through the heat insulation capacity of the cross heat insulation plate 11 itself, four independent heat dissipation spaces can be formed, and the heat can be dispersed and separated for individual heat dissipation. This can effectively dissipate heat from the components that generate a lot of heat and better protect the components that are not heat resistant.

[0031] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the bottom of the four lower shell plates 31 are fixedly connected to the air guide shrouds 34 by bolts, and air guide plates 35 are provided at the bottom of the four lower shell plates 31 near the outer side of the air guide shrouds 34. There are a total of seven air guide plates 35, and the seven air guide plates 35 are arranged in a divergent manner on the outer side of the air guide shrouds 34. The air guide plates 35 can guide the airflow, thereby accelerating the airflow rate at the bottom of the lower shell plates 31 and improving the heat dissipation effect. A fan 36 is fixedly installed inside the air guide shrouds 34.

[0032] The specific implementation method is as follows: When performing active heat dissipation, the fan 36 is controlled to work. The fan 36 blows air into the interior of the air guide shroud 34. The air enters the space between adjacent air guide plates 35 under the guidance. The air accelerates and contacts the air guide plates 35 and the lower shell plate 31, improving the heat exchange rate and thus improving the heat dissipation of the RFID electronic tag reader. The airflow flowing in four directions can also dissipate heat in the four independent heat dissipation spaces inside the RFID electronic tag reader.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
