Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of industrial tablet computers, in particular to an industrial tablet computer provided with a sealed heat dissipation structure. Background Art

[0002] Industrial tablets are industrial control computers designed for industrial use. Their basic performance and compatibility are similar to those of commercial computers, but they focus more on security and stability in different environments. Since industrial tablets generate a lot of heat when running high-load tasks for a long time, if this heat cannot be dissipated in time, it will lead to tablet performance degradation, system instability, and even hardware damage.

[0003] Traditional industrial tablet computers typically use cooling fans or heat sinks to remove internal heat from the tablet. While this can alleviate the heat dissipation problem to a certain extent, it often suffers from problems such as low heat dissipation efficiency and poor sealing. This is especially true in industrial environments with high sealing requirements. Traditional heat dissipation methods are unable to meet the dual requirements of tablet computers for both efficient heat dissipation and good sealing. Therefore, we propose an industrial tablet computer with a sealed heat dissipation structure to address the above issues. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the conventional heat dissipation method of the prior art, which uses a heat dissipation fan or a heat sink to remove the heat from the industrial tablet computer, such as low heat dissipation efficiency and poor sealing, and to propose an industrial tablet computer with a sealed heat dissipation structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An industrial tablet computer with a sealed heat dissipation structure includes a tablet computer body, a heat dissipation box embedded in the bottom of the tablet computer body to seal the bottom of the tablet computer body, a first through hole and a second through hole respectively formed on the top of the heat dissipation box, each of which is connected to the interior of the tablet computer body, and a heat-conducting aluminum plate provided on the bottom of the heat dissipation box. The industrial tablet computer also includes:

[0007] A fixing component is provided on the outside of the heat dissipation box and is used to fix the tablet computer body and the heat dissipation box;

[0008] The heat dissipation component is arranged inside the heat dissipation box and is used to dissipate heat from the tablet computer.

[0009] In one possible design, the fixing assembly includes four fixing ears, which are arranged at equal intervals on the outer wall of the heat dissipation box. The four fixing ears are all threaded with a first screw. The bottom of the tablet computer body is provided with fixing grooves corresponding to the four fixing ears. The four fixing ears are respectively located inside the corresponding fixing grooves. The four first screws are all connected to the tablet computer body screws. A sealing strip for sealing is provided inside the tablet computer body at the top of the heat dissipation box.

[0010] In one possible design, the heat dissipation assembly includes a heat conducting plate, which is fixedly connected to the CPU of the tablet computer body that needs to dissipate heat by a second screw, and a water cooling head is fixedly connected to the bottom of the heat conducting plate, and the bottom of the water cooling head passes through the first through hole and extends to the interior of the heat dissipation box, and a heat conducting pipe is fixedly provided on the top inner wall of the heat dissipation box, one end of the heat conducting pipe is connected to the water outlet of the water cooling head, and a water pump is fixedly provided on the top inner wall of the heat dissipation box, and the water outlet of the water pump is connected to the water inlet of the water cooling head, and the water inlet of the water pump is connected to the other end of the heat conducting pipe.

[0011] In a possible design, heat dissipation fins are provided on the heat conducting pipe, a heat dissipation fan is fixedly provided on the top inner wall of the heat dissipation box, and an air outlet of the heat dissipation fan faces the heat dissipation fins.

[0012] In a possible design, four fixing blocks are symmetrically fixed on the top inner wall of the heat dissipation box, and threaded holes are provided in the four fixing blocks. Mounting holes corresponding to the four threaded holes are opened on the heat-conducting aluminum plate, and third screws are threadedly connected in the four mounting holes. The four third screws are respectively threadedly connected to the corresponding threaded holes.

[0013] In a possible design, the top of the heat-conducting aluminum plate contacts the heat sink fins, so that the heat of the heat sink fins is transferred to the outside of the tablet computer body through the heat-conducting aluminum plate.

[0014] In one possible design, two support plates are provided on the top inner wall of the heat dissipation box, and the bottoms of the two support plates are in conflict with the thermal conductive aluminum plate, which are used to divide the internal space of the heat dissipation box, so that the wind blown out by the cooling fan can circulate internally in the heat dissipation box, and can support the thermal conductive aluminum plate to prevent the thermal conductive aluminum plate from sinking, which affects heat dissipation and use.

[0015] In the present application, when the tablet computer is running, the heat generated by the CPU and other heating components is transferred to the water-cooling head through the heat-conducting plate. During the process, the water pump is started to pump water from one end of the heat-conducting pipe into the water-cooling head. After absorbing the heat, the water becomes hot water and flows out from the water outlet of the water-cooling head and enters the heat-conducting pipe. The hot water flows in the heat-conducting pipe and transfers the heat to the heat dissipation fins. At the same time, the heat dissipation fan is started, and the air blown out not only blows directly to the heat dissipation fins to accelerate the dissipation of heat, but also passes through the first through hole, the second through hole on the heat dissipation box and the two support plates therein for partitioning to form an internal circulation of the air flow in the heat dissipation box, thereby further accelerating the dissipation of heat. At the same time, the support plate supports the heat-conducting aluminum plate to prevent it from sagging and affecting the heat dissipation effect.

[0016] Because the heat-conducting aluminum plate is connected to the heat-dissipating fins, the heat transferred to the heat-dissipating fins is conducted to the heat-conducting aluminum plate, which then conducts the heat to the outside of the tablet computer, thereby reducing the temperature inside the heat dissipation box. The cold water after being dissipated by the heat-dissipating fins returns to the water inlet of the water pump, forming a cycle.

[0017] The fixing assembly firmly connects the tablet computer body and the heat dissipation box through four fixing ears and a first screw, and ensures the sealing of the tablet computer through a sealing strip.

[0018] Beneficial effects:

[0019] In the utility model, the industrial tablet computer with a sealed heat dissipation structure not only achieves efficient heat dissipation of the tablet computer but also ensures the sealing of the tablet computer by embedding a heat dissipation box and a heat dissipation component therein at the bottom of the tablet computer body, thus meeting the heat dissipation and sealing requirements of the tablet computer in the industrial environment.

[0020] In the utility model, the industrial tablet computer provided with a sealed heat dissipation structure is designed so that the connection between the tablet computer body and the heat dissipation box is more stable, thereby avoiding loosening of the connection due to vibration or external force, and improving the stability and service life of the tablet computer.

[0021] In the utility model, the industrial tablet computer provided with a sealed heat dissipation structure adopts a heat dissipation component that combines water cooling and air cooling. Through the synergistic effect of components such as the heat conducting plate, water cooling head, heat conducting pipe, water pump and heat dissipation fan, the rapid transfer and dissipation of heat is achieved, the heat dissipation efficiency is improved, and the noise level is reduced.

[0022] In the utility model, by embedding the heat dissipation box and the heat dissipation component therein at the bottom of the tablet computer body, not only efficient heat dissipation of the tablet computer is achieved, but also the sealing of the tablet computer is ensured, meeting the heat dissipation and sealing requirements of the tablet computer in the industrial environment. The synergistic effect of the heat conduction plate, water cooling head, heat conduction pipe, water pump, heat dissipation fan and heat conduction aluminum plate and other components in the heat dissipation component realizes rapid transfer and dissipation of heat, improves heat dissipation efficiency and reduces noise level.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1: Reference Figure 1-4 An industrial tablet computer includes a tablet computer body 1 and a heat sink 2. Heat sink 2 is embedded in the bottom of tablet computer body 1. Heat sink 2 is designed to seal the bottom of tablet computer body 1 and simultaneously dissipate heat. Heat sink 2 has a first through hole 201 and a second through hole 202 defined in the top. These two through holes communicate with the interior of tablet computer body 1, facilitating heat transfer and the placement of heat dissipation components.

[0030] A heat-conducting aluminum plate 11 is provided at the bottom of the heat dissipation box 2 . The heat-conducting aluminum plate 11 has good heat-conducting performance and can effectively conduct the heat inside the heat dissipation box 2 to the outside of the tablet computer body 1 .

[0031] To secure the tablet computer body 1 to the heat sink 2, a fixing assembly is provided. This fixing assembly comprises four fixing ears 4, equally spaced on the outer wall of the heat sink 2. Each ear 4 is threaded with a first screw. The bottom of the tablet computer body 1 is provided with fixing slots 3 corresponding to the four fixing ears 4. When the heat sink 2 is inserted into the bottom of the tablet computer body 1, the four fixing ears 4 are located within the corresponding fixing slots 3. By tightening the four first screws, the tablet computer body 1 and the heat sink 2 are securely fixed.

[0032] In addition, in order to enhance the sealing performance, a sealing strip 14 is provided on the top of the heat dissipation box 2 inside the tablet computer body 1. The sealing strip 14 can effectively prevent dust and moisture from entering the tablet computer, thereby ensuring the stable operation of the device.

[0033] The heat dissipation assembly includes a heat conducting plate 5, which is fixedly connected to the CPU inside the tablet computer body 1 that needs heat dissipation via a second screw. A water cooling head 6 is fixedly connected to the bottom of the heat conducting plate 5, and the bottom of the water cooling head 6 passes through the first through hole 201 and extends into the interior of the heat dissipation box 2. A heat pipe 7 and a water pump 8 are fixedly installed on the top inner wall of the heat dissipation box 2. One end of the heat pipe 7 is connected to the water outlet of the water cooling head 6, while the water outlet of the water pump 8 is connected to the water inlet of the water cooling head 6. The water inlet of the water pump 8 is connected to the other end of the heat pipe 7, thereby forming a circulating water circuit.

[0034] When the tablet is running, the heat generated by the CPU is transferred to the water cooling head 6 through the heat conducting plate 5, then carried away by the circulating water circuit and dissipated through the heat pipe 7. To further improve the heat dissipation efficiency, the heat pipe 7 is also provided with heat dissipation fins 9, which can increase the heat dissipation area and improve the heat dissipation effect.

[0035] At the same time, a heat dissipation fan 10 is fixedly provided on the top inner wall of the heat dissipation box 2, and the air outlet of the heat dissipation fan 10 faces the heat dissipation fins 9. When the heat dissipation fan 10 is working, it can accelerate the air flow around the heat dissipation fins 9, thereby further improving the heat dissipation efficiency.

[0036] Four fixing blocks 13 are symmetrically mounted on the top inner wall of the heat sink 2, each with a threaded hole. Mounting holes corresponding to the four threaded holes are provided on the heat-conducting aluminum plate 11. Four third screws are threaded into the corresponding threaded holes to secure the heat-conducting aluminum plate 11 within the heat sink 2.

[0037] This application can be used in the field of industrial tablet computer heat dissipation technology, and can also be used in other fields applicable to this application.

[0038] Example 2: Reference Figure 2-4 , improved on the basis of embodiment 1: an industrial tablet computer with a sealed heat dissipation structure, which is applied to the field of heat dissipation technology of industrial tablet computers. In addition, the top of the heat-conducting aluminum plate 11 and the heat dissipation fins 9 are in conflict with each other, so that the heat of the heat dissipation fins 9 can be conducted to the outside of the tablet computer body 1 through the heat-conducting aluminum plate 11, further improving the heat dissipation effect.

[0039] To prevent the heat-conducting aluminum plate 11 from denting and affecting heat dissipation and usability, two support plates 12 are installed on the top inner wall of the heat dissipation box 2. The bottoms of these support plates 12 contact the heat-conducting aluminum plate 11, dividing the internal space of the heat dissipation box 2. This way, when the cooling fan 10 is operating, the air blown out can circulate within the heat dissipation box 2, further improving heat dissipation efficiency. At the same time, the support plates 12 also support the heat-conducting aluminum plate 11, preventing it from denting.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the devices are commonplace and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
