Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of computer sealing, and particularly relates to a tablet computer with a high-closeness waterproof structure. BACKGROUND

[0002] Industrial tablet computers are widely used in industrial control, automated production, outdoor operation and the like, and factors such as moisture, water mist and liquid splashing in an industrial environment also require the equipment to have good waterproof capability. In order to meet the heat dissipation requirement, liquid cooling heat dissipation technology is widely used in industrial tablet computers. Compared with traditional air cooling heat dissipation, liquid cooling heat dissipation has higher heat conduction efficiency and can more effectively transfer heat from a heat source to a heat sink.

[0003] A liquid cooling system is usually composed of a cooling head, a pump, a heat dissipation pipeline and a heat sink and the like. The cooling head is directly in contact with a heat generating element such as a CPU, and heat is taken away through circulation of cooling liquid. However, the liquid cooling system has a risk of liquid leakage, and the joint of the cooling head is most prone to liquid leakage.

[0004] When liquid leakage occurs, although timely power-off can avoid short circuit of electronic elements, the liquid leakage is usually caused by sealing failure or pipeline damage, and the cooling liquid will continue to seep out, leading to diffusion of the cooling liquid along the internal structure to an area far away from the leakage point, and expansion of the damage range.

[0005] Since disassembly of the computer requires professional technology and tools, it is difficult to operate the plugging of the liquid leakage part, and thus the computer needs to be repaired. The bumping and vibration during transportation for repair will accelerate the leakage of the cooling liquid. The corrosive cooling liquid will not only cause damage to the transportation tool, but also spread in the equipment, continuously corroding the electronic elements. Even if the leakage point is repaired subsequently, the equipment may still frequently malfunction due to circuit risks.

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0048] As Figures 1 to 11The high-closeness waterproof structure tablet computer comprises a body, a heat dissipation part, an air exhaust part, a buffer mechanism, a smearing mechanism and a tapping mechanism.

[0049] The body comprises an outer shell 1, a protective layer 2 and a back cover 5, the front of the outer shell 1 is a display screen, the back is a back plate, the protective layer 2 is fixedly installed on the outer wall of the outer shell 1, the protective layer 2 is made of rubber material and is used for wrapping the outer wall except the side of the display screen, and the back cover 5 is fixedly installed on the back of the outer shell 1, the middle part of the back cover 5 is raised and used for providing a mounting space for electronic elements.

[0050] The heat dissipation part comprises a contact plate 14 and a cooling head assembly 13 with a circulating water pump, the cooling head assembly 13 can be a forced refrigeration liquid cooling head with a semiconductor refrigeration sheet arranged inside, a copper pipe interface is arranged outside the cooling head assembly 13, the circulating water pump inside the cooling head assembly 13 is used for controlling the internal cooling liquid to flow in the copper pipe and the cooling head assembly 13, so that heat is absorbed in the closed space.

[0051] The heat absorption end of the cooling head assembly 13 is in contact with the CPU of the body through the contact plate 14, in the embodiment, the contact plate 14 is made of copper plate, one side of the contact plate 14 is located inside the cooling head assembly 13 and is in contact with the cooling liquid, and the other side of the contact plate 14 is located outside the cooling head assembly 13 and is coated with heat-conducting silicone grease and is used for being in contact with the heat generating part of the CPU.

[0052] The heat dissipation part is used for blowing air towards the heat dissipation end of the cooling head assembly 13, so that the cooling liquid inside the cooling head assembly 13 is cooled.

[0053] The buffer mechanism comprises an external connector 3, a buffer barrel 16 and a switching plate 9, the switching plate 9 is rotationally arranged outside the cooling head assembly 13, the external connector 3 is fixedly installed on the outer wall of the back cover 5, and the external connector 3 is used for being in one-way communication with the inner cavity of the switching plate 9.

[0054] The smearing mechanism comprises a closing plate 32, a scraping plate 35 and a flow guide groove 21 arranged inside the switching plate 9, the inner cavity of the buffer barrel 16 is in communication with the inner cavity of the flow guide groove 21, and one end of the flow guide groove 21 penetrates out of the outer wall of the switching plate 9.

[0055] The internal part of the cooling head assembly 13 is provided with a monitoring module (a cooling liquid pressure monitoring module is selected), when the joint part outside the cooling head assembly 13 leaks, the monitoring module monitors and transmits the liquid leakage information to the CPU, and the display screen displays the liquid leakage reminding information.

[0056] When the liquid leakage reminding information appears, the syringe is inserted into the external connector 3, then the silicone waterproof sealant is pushed into the inner cavity of the flow guide groove 21, at this time, the discharge end of the flow guide groove 21 is closed, the silicone waterproof sealant enters the inner cavity of the buffer barrel 16, and the temporary storage of the silicone waterproof sealant is realized.

[0057] The closing plate 32 is elastically arranged at the bottom of the adapter plate 9 and is used to intermittently close the flow guide groove 21. The outer wall of the closing plate 32 is attached to the outer wall of the adapter plate 9. During the rotation of the adapter plate 9, the closing plate 32 intermittently closes the flow guide groove 21. During the injection of the glue, the adapter plate 9 remains fixed, and the closing plate 32 remains in the state of closing the flow guide groove 21.

[0058] The scraper 35 is fixedly installed on the bottom surface of the closing plate 32. After the injection of the glue, the syringe is pulled out. At this time, the internal space of the buffer cylinder 16 is compressed, so that the glue has a tendency to be discharged from the flow guide groove 21. At this time, the display screen side of the shell 1 is upward, that is, the flow guide groove 21 is directed to the ground. At this time, the adapter plate 9 is rotated along the outer wall of the cooling head assembly 13, and the closing plate 32 and the scraper 35 are rotated along the outer wall of the cooling head assembly 13. During this process, the closing plate 32 is synchronously intermittently slid along the bottom surface of the adapter plate 9, so as to cause the flow guide groove 21 to be intermittently communicated, the glue to be discharged, and the glue discharged from the flow guide groove 21 to be evenly coated on the joint of the outer wall of the cooling head assembly 13 by the scraper 35, so as to achieve temporary plugging of the liquid leakage and prevent the cooling liquid from continuing to leak and pollute the internal electronic components of the computer.

[0059] The process of injecting glue can be quickly handled by ordinary people (non-professional computer maintenance staff).

The time for repair is provided, and the damage of the cooling liquid leakage to the internal components of the tablet computer is prevented in the first time. The time for subsequent maintenance of the equipment is saved. The emergency treatment in the sudden leakage scene is suitable. In a simple and efficient way, the safety of the equipment is protected.

[0060] At the same time, the closing plate 32 and the scraper 35 are intermittently slid during the rotation of the adapter plate 9, because the glue has poor fluidity, so that the time for the glue to flow downward to the joint of the cooling head assembly 13 is provided. Compared with the synchronous scraping method when the glue is discharged, the phenomenon of missed coating caused by the joint not being in contact with the glue is effectively prevented, and the quality of temporary plugging is maintained.
