Description

Technical Field

[0001] This utility model relates to the field of terminal device technology, specifically a terminal device with electromagnetic compatibility design. Background Technology

[0002] Electromagnetic compatibility (EMC) design of terminal devices is a key technological product that ensures stable operation of equipment in complex electromagnetic environments without interfering with other devices. Its design must comprehensively consider the suppression of electromagnetic interference, the reduction of electromagnetic susceptibility, and the overall EMC of the system. This is achieved by blocking the propagation path of electromagnetic waves through a metal casing or shielding layer, thus reducing radiated interference. Selecting metals with good conductivity, such as copper and aluminum, as shielding materials ensures the integrity of the shielding structure and prevents leakage due to holes or gaps.

[0003] In existing technologies, such as the terminal device based on electromagnetic compatibility design disclosed in announcement number CN209842522U, a panel and a housing are included. The panel is provided with a display screen hole, key holes, and screen edge keys. An interface board is provided inside the housing. An LCD screen is provided on the front of the interface board. A keyboard board and a touch screen are provided on the LCD screen. The keyboard board is connected to the screen edge keys through the key holes. The touch screen is fixed to the panel through the display screen hole. An external memory, a CPU module, and a first filter component are provided on the back of the interface board. This reduces interference radiation from the source, reduces the difficulty of housing shielding measures, enhances the self-compatibility inside the chassis, reduces the electromagnetic emission of the vehicle commander terminal, better meets the requirements of RE102, effectively reduces electromagnetic radiation, and enhances the electromagnetic shielding effectiveness of the whole machine. Through the detection and preliminary test of electromagnetic radiation of the actual object, the above-mentioned vehicle commander terminal structure was finally formed, which effectively suppresses electromagnetic radiation.

[0004] Existing terminal devices reduce interference radiation at the source, simplify the shielding measures, enhance the internal compatibility of the chassis, and reduce electromagnetic emissions from the vehicle terminal, thus better meeting the requirements of RE102. However, due to the overall sealing of the device, the heat generated by the internal components during operation cannot be dissipated in time, resulting in severe overheating of the components and affecting their service life. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology involves sealing the entire device, the heat generated by the internal components during operation cannot be dissipated in time, resulting in severe overheating of the components and affecting their service life.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An electromagnetic compatibility-designed terminal device includes a device housing, with a heat dissipation mechanism at the lower end of the housing for dissipating heat from the device interior, and a cooling mechanism on the right side of the heat dissipation mechanism for cooling the coolant.

[0009] The heat dissipation mechanism includes a liquid storage tank, which is welded to the lower surface of the device housing. A submersible pump is fixed inside the liquid storage tank by screws. The output end of the submersible pump is connected to a delivery pipe. The end of the delivery pipe is connected to a heat-conducting plate fixed to the inner wall of the device housing. An insulating heat-conducting pad is placed on the upper surface of the heat-conducting plate.

[0010] As a further improvement of this utility model: the upper surface of the insulating thermal pad is connected to a circuit board that is fixedly connected to the outer shell of the device, and the lower end of the thermal plate is connected to a return pipe that is connected to the liquid storage tank.

[0011] As a further improvement of this utility model: the cooling mechanism includes a heat-conducting pipe, and a plurality of heat-conducting pipes are provided. The heat-conducting pipes penetrate the inner wall of the liquid storage tank, and heat dissipation fins are welded to the ends of the heat-conducting pipes.

[0012] As a further improvement of this utility model: a mounting plate is connected to the right side of the heat dissipation fins, and a cooling fan is installed inside the mounting plate.

[0013] As a further improvement of this utility model, a shielding inner layer is fixed to the inner surface of the device housing.

[0014] As a further improvement of this utility model: a fixing cover is installed on the upper surface of the device housing, and a display screen is embedded on the upper surface of the fixing cover.

[0015] As a further improvement of this utility model: two sets of fixing bolts are symmetrically installed on the upper end of the fixing cover, and the ends of the two sets of fixing bolts are threaded with threaded grooves opened on the outer shell of the device.

[0016] As a further improvement of this utility model: three first filter capacitors are installed on the upper surface of the circuit board, and a second filter capacitor is installed to the left of the first filter capacitors.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model transfers heat to the heat-conducting plate through an insulating thermal pad, while the coolant absorbs the heat from the heat-conducting plate, thereby indirectly dissipating heat from electronic components. The cooling fan on the mounting plate blows air onto the heat sink fins, thereby improving the cooling effect of the coolant and ensuring the effectiveness of subsequent circulation.

[0019] 2. This utility model allows for the removal of the fixing bolts on the fixing cover, separating the fixing bolts from the threaded groove and releasing the fixing cover from its fixation, thus facilitating the maintenance of the internal parts. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Please see Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a terminal device with electromagnetic compatibility design, including a device housing 1. The lower end of the device housing 1 is provided with a heat dissipation mechanism for dissipating heat inside the device, and the right side of the heat dissipation mechanism is provided with a cooling mechanism for cooling the coolant.

[0031] The heat dissipation mechanism includes a liquid storage tank 2, which is welded to the lower surface of the device housing 1. A submersible pump 21 is fixed inside the liquid storage tank 2 by screws. The output end of the submersible pump 21 is connected to a delivery pipe 22. The end of the delivery pipe 22 is connected to a heat-conducting plate 23 fixed to the inner wall of the device housing 1. An insulating heat-conducting pad 24 is placed on the upper surface of the heat-conducting plate 23.

[0032] Specifically, the upper surface of the insulating heat-conducting pad 24 is connected to a circuit board 25 that is fixedly connected to the outer casing 1 of the device, and the lower end of the heat-conducting plate 23 is connected to a return pipe 26 that is connected to the liquid storage tank 2.

[0033] Furthermore, the insulating thermal pad 24 absorbs the heat from the circuit board 25 and transfers the heat to the heat-conducting plate 23.

[0034] Specifically, the cooling mechanism includes heat pipes 3, and there are several heat pipes 3. The heat pipes 3 penetrate the inner wall of the liquid storage tank 2, and heat dissipation fins 31 are welded to the end of the heat pipes 3.

[0035] Furthermore, the heat pipe 3 absorbs heat from the coolant and transfers the heat to the surface of the heat dissipation fins 31, allowing the heat dissipation fins 31 to dissipate the heat to the outside.

[0036] Specifically, a mounting plate 32 is connected to the right side of the heat dissipation fins 31, and a cooling fan 33 is installed inside the mounting plate 32.

[0037] Furthermore, the cooling fan 33 on the mounting plate 32 can blow air onto the heat sink 31, thereby improving the cooling effect of the coolant and ensuring the effect of subsequent circulation.

[0038] During use, the electronic components on the circuit board 25 generate heat during operation. The heat is absorbed by the insulating thermal pad 24 and transferred to the heat-conducting plate 23. The submersible pump 21 installed in the liquid storage tank 2 starts, which draws out the coolant from the liquid storage tank 2 and delivers it to the heat-conducting plate 23 through the delivery pipe 22. The coolant absorbs the heat in the heat-conducting plate 23, thereby indirectly dissipating heat from the electronic components and effectively reducing the occurrence of overheating of the electronic components. The coolant that has absorbed heat will flow back into the liquid storage tank 2 through the return pipe 26 for recycling. The heat is also absorbed by the heat-conducting pipe 3 installed on the inner wall of the liquid storage tank 2 and transferred to the surface of the heat dissipation fins 31, allowing the heat dissipation fins 31 to dissipate heat to the outside. The cooling fan 33 on the mounting plate 32 blows air onto the heat dissipation fins 31, thereby improving the cooling effect of the coolant and ensuring the effect of subsequent circulation.

[0039] In summary, when the terminal device with this electromagnetic compatibility design is in use, the insulating thermal pad 24 absorbs the heat from the circuit board 25, the coolant absorbs the heat from the heat-conducting plate 23, thus indirectly dissipating heat from the electronic components. The heat pipe 3 absorbs the heat from the coolant, and the cooling fan 33 blows air onto the heat dissipation fins 31, thereby improving the cooling effect of the coolant and ensuring the effect of subsequent circulation.

[0040] Example 2

[0041] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0042] Specifically, a shielding inner layer 4 is fixed to the inner surface of the device housing 1, and a fixing cover 5 is installed on the upper surface of the device housing 1. A display screen 6 is embedded on the upper surface of the fixing cover 5.

[0043] Furthermore, the display screen 6 installed on the fixed cover 5 facilitates the display of the device's real-time operating status.

[0044] Specifically, two sets of fixing bolts 7 are symmetrically installed on the upper end of the fixing cover 5, and the ends of the two sets of fixing bolts 7 are threadedly connected to threaded grooves 8 opened on the outer shell 1 of the device.

[0045] Furthermore, by unscrewing the fixing bolts 7 provided on the fixing cover 5, the fixing bolts 7 are separated from the threaded groove 8, and the fixing cover 5 can be disassembled.

[0046] Specifically, three first filter capacitors 9 are mounted on the upper surface of the circuit board 25, and a second filter capacitor 10 is mounted on the left side of the first filter capacitors 9.

[0047] Furthermore, the first filter capacitor 9 and the second filter capacitor 10 provided on the circuit board 25 can filter the electrical signals of the interface, thereby improving the electromagnetic compatibility shielding effect.

[0048] In use, the outer casing 1 is installed in a suitable position and connected to external devices through the interface provided on the outer casing 1. Electromagnetic compatibility shielding is performed by the shielding inner layer 4 provided inside the outer casing 1. The first filter capacitor 9 and the second filter capacitor 10 provided on the circuit board 25 can filter the electrical signals of the interface, thereby improving the electromagnetic compatibility shielding effect. The display screen 6 provided on the fixed cover 5 can conveniently display the real-time operating status of the device. By unscrewing the fixing bolt 7 provided on the fixed cover 5, the fixing bolt 7 is separated from the threaded groove 8, and the fixing cover 5 is released, which can disassemble the fixed cover 5 and facilitate the maintenance of the internal parts.

[0049] In summary, when the terminal device with this electromagnetic compatibility design is in use, the insulating thermal pad 24 absorbs the heat from the circuit board 25, the coolant absorbs the heat from the heat-conducting plate 23, thus indirectly dissipating heat from the electronic components. The heat pipe 3 absorbs the heat from the coolant, and the cooling fan 33 blows air onto the heat dissipation fins 31, thereby improving the cooling effect of the coolant and ensuring the effect of subsequent circulation. Furthermore, by unscrewing the fixing bolt 7 on the fixing cover 5, the fixing bolt 7 is separated from the threaded groove 8, allowing the fixing cover 5 to be disassembled, which facilitates the maintenance of the internal components.
