[0054] Big data is a collection of data characterized by large capacity, multiple types, fast access speed and application value. Analyzing big data in modern society can produce accurate results for various needs. Terminals are needed in big data analysis and processing to display data and input and output data.

[0055] The terminal generates a lot of heat during operation, and a heat dissipation device is needed to cool the terminal. Existing terminals usually use fans for heat dissipation.

[0056] However, the heat dissipation efficiency of the fan is low, and the heat inside the terminal cannot be efficiently and quickly diffused to the outside. Long-term use may cause the terminal to crash, reducing the service life and practicality of the terminal.

[0057] In view of this, the terminal provided by the present application dissipates heat inside the terminal body by setting a circular tube inside the terminal body and then injecting water into the circular tube, and then discharges the heat to the outside of the terminal body through the exhaust fan on the top of the terminal body. At the same time, a refrigeration component is set inside the terminal body, and the refrigeration component includes a refrigerator and at least one fan. Starting the refrigerator can cool the inside of the terminal body, and then the fan on the side wall of the terminal body is used to circulate the cold air generated by the cold end of the refrigerator through the air, thereby realizing efficient heat dissipation of the terminal and improving the service life and practicality of the terminal.

[0058] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

Figure 4 for Figure 2 A schematic diagram of the structure of the partition in FIG. Figure 5 A schematic diagram of the structure of a mobile component in a terminal provided in an embodiment of the present application.

[0060] See also Figure 1 and Figure 2 A terminal provided in the present application includes a terminal body 100, a heat dissipation component 200 and a refrigeration component 300. The heat dissipation component 200 includes a circular pipe 210 and at least one exhaust fan 220. The circular pipe 210 is arranged inside the terminal body 100, and the exhaust fan 220 is installed on the top of the terminal body 100 to discharge the heat in the terminal body 100; the refrigeration component 300 includes a refrigerator 310 and at least one fan 320. The refrigerator 310 is installed on the inner bottom wall of the terminal body 100, and the cold end of the refrigerator 310 faces the circular pipe 210, and the hot end of the refrigerator 310 faces away from the circular pipe 210; the fan 320 is installed on the side wall of the terminal body 100 to accelerate the circulation of air above the refrigerator 310.

[0061] In the present application, the function of the meandering tube 210 is to exchange heat inside the terminal body 100. By injecting water into the meandering tube 210, the inside of the terminal body 100 is water-cooled. The meandering design can increase the heat exchange contact area, thereby improving the heat exchange effect.

[0062] At the same time, in order to discharge the heat generated by the terminal to the outside of the terminal body 100, an exhaust fan 220 is arranged on the top of the terminal body 100. When the exhaust fan 220 is started, the heat generated by the terminal body 100 during operation can be discharged to the outside of the terminal body 100. The number and layout of the exhaust fans 220 are only given for example, and the specific ones can be set according to actual needs, and this embodiment is not limited here.

[0063] In specific implementation, a refrigerator 310 is provided on the inner bottom wall of the terminal body 100, and cold air is produced through the cold end of the refrigerator 310 to reduce the temperature inside the terminal body 100, further improving the heat dissipation efficiency inside the terminal body 100. At the same time, a fan 320 is installed on the side wall of the terminal body 100. When the fan 320 is started, the cold air generated by the refrigerator 310 can be circulated inside the terminal body 100 through the air, thereby improving the cooling efficiency.

[0064] It is understandable that the number and layout of the fans 320 are given for exemplary purposes only and can be set according to actual needs, and this embodiment does not limit this.

[0065] Therefore, through the coordinated use of the loop tube 210, the exhaust fan 220, the cooler 310 and the fan 320, efficient heat dissipation of the terminal is achieved, thereby improving the service life and practicality of the terminal.

[0066] See also Figure 1 and Figure 2In the embodiment of the present application, a water inlet 110 communicating with the loop pipe 210 is disposed on one side of the terminal body 100 , and a water outlet 120 communicating with the loop pipe 210 is disposed on the other side of the terminal body 100 .

[0067] Among them, in order to realize water-cooled heat exchange, a water inlet 110 and a water outlet 120 with a control valve are arranged on one side of the terminal body 100, and the water inlet 110 and the water outlet 120 are respectively connected to the two ends of the loop pipe 210. The control valve arranged at the water inlet 110 allows the external water body to enter the loop pipe 210 inside the terminal body 100 through the water inlet 110, and then the heat exchange is performed on the inside of the terminal body 100 through the water body, and the heat inside the terminal body 100 is dissipated through the water outlet 120. Therefore, the temperature inside the terminal body 100 can be reduced, the normal operation of the terminal body 100 can be guaranteed, and the service life of the electrical components inside the terminal body 100 can be improved.

[0068] See also Figure 1 and Figure 2 In the embodiment of the present application, at least one filter 130 is embedded in the side wall of the terminal body 100, and the filter 130 is arranged in a one-to-one correspondence with a side of the fan 320 away from the meander tube 210.

[0069] In the present application, a filter 130 is embedded in the side wall of the terminal body 100. The filter 130 may be rectangular, circular or other suitable shapes, and this embodiment is not limited here. The purpose of setting the filter 130 is to filter dust and prevent dust from entering the interior of the terminal body 100 through the fan 320, thereby ensuring the normal use of the terminal.

[0070] During installation, the filter 130 is disposed on a side of the fan 320 that is away from the loop-shaped tube 210 , and is disposed one-to-one with the fan 320 to ensure the dust isolation effect of the filter 130 .

[0071] See also Figure 2 In the embodiment of the present application, the refrigerator 310 is a semiconductor refrigerator.

[0072] In some embodiments, the refrigerator 310 may be a semiconductor refrigerator, which has the characteristics of no noise, no vibration, small size, light weight, etc., and is reliable in operation, easy to operate, and easy to adjust the cooling capacity.

[0073] The size and model of the semiconductor refrigerator can be set according to actual needs, and this embodiment does not limit it.

[0074] It can be understood that during the operation of the terminal body 100, the semiconductor refrigerator can be started by a controller (not shown in the figure), the cold end of the semiconductor refrigerator is facing the circular tube 210, and cold air is generated through the cold end of the semiconductor refrigerator to reduce the temperature inside the terminal body 100 and further improve the heat dissipation efficiency inside the terminal body 100.

[0075] See also Figure 3 In the embodiment of the present application, a screen 221 is provided at one end of the exhaust fan 220 away from the terminal body 100; a dust cleaning rod 222 is provided on the side of the screen 221 away from the exhaust fan 220, and the dust cleaning rod 222 is rotatably connected to the output shaft of the exhaust fan 220.

[0076] In a specific implementation, a screen 221 is installed at one end of the exhaust fan 220 away from the terminal body 100. The purpose of setting the screen 221 is to filter dust and reduce dust falling into the interior of the terminal body 100 without affecting the ventilation and heat dissipation function of the exhaust fan 220.

[0077] It is understandable that in order to facilitate the cleaning of dust on the surface of the screen 221, the output shaft of the exhaust fan 220 is rotatably connected to a cleaning rod 222. Regularly using the cleaning rod 222 to clean the dust accumulated on the surface of the screen 221 can effectively increase the air circulation rate of the terminal body 100, thereby improving the heat dissipation efficiency of the terminal body 100.

[0078] See also Figure 2 and Figure 3 In the embodiment of the present application, at least one mounting plate 400 is further included, and one end of the exhaust fan 220 facing the terminal body 100 is fixedly connected to the mounting plate 400, and the mounting plate 400 is fixedly connected to the top of the terminal body 100 by bolts 500; the top of the terminal body 100 has a heat dissipation channel 600, and the exhaust fan 220 is connected to the interior of the terminal body 100 through the heat dissipation channel 600.

[0079] In order to fix the exhaust fan 220 on the top of the terminal body 100, a mounting plate 400 may be provided at one end of the exhaust fan 220 facing the terminal body 100. The mounting plate 400 and the exhaust fan 220 may be an integrally formed part, so that it is convenient to process the exhaust fan 220 and the mounting plate 400. The exhaust fan 220 and the mounting plate 400 may also be fixedly connected by welding or other installation methods, in order to stably mount the exhaust fan 220 on the mounting plate 400, which is not limited in this embodiment.

[0080] In the present application, during installation, the mounting plate 400 is detachably connected to the top of the terminal body 100 by bolts 500. Such a design facilitates the disassembly and installation of the mounting plate 400, thereby facilitating the inspection and maintenance of the exhaust fan 220 and the cleaning of the screen 221.

[0081] It can be understood that the number and layout of the bolts 500 are only given for example, and can be set according to actual needs, and this embodiment is not limited thereto.

[0082] In a specific implementation, the exhaust fan 220 is connected to the interior of the terminal body 100 through the heat dissipation channel 600 at the top of the terminal body 100. The heat inside the terminal body 100 is discharged to the outside of the terminal body 100 through the heat dissipation channel 600 using the exhaust fan 220, thereby improving the heat dissipation efficiency.

[0083] See also Figure 2 and Figure 4 In the embodiment of the present application, a partition 140 is fixedly connected to the inner wall of the terminal body 100, one side of the partition 140 has a groove 141 corresponding to the ring-shaped tube 210, and the ring-shaped tube 210 is partially inserted into the groove 141, and the partition 140 has a plurality of through holes 142; the refrigerator 310 and the fan 320 are located below the partition 140.

[0084] In the present application, in order to increase the air circulation rate inside the terminal body 100, a partition 140 can be set inside the terminal body 100. In order to fit the partition 140 inside the terminal body 100, a groove 141 corresponding to the circular tube 210 can be set on one side of the partition 140. Therefore, during installation, the circular tube 210 is partially inserted into the groove 141.

[0085] In some embodiments, the partition 140 can be fixedly connected to the inner wall of the terminal body 100 by plug-in installation, and the partition 140 can also be installed by other connection methods to achieve fixed connection between the partition 140 and the inner wall of the terminal body 100. This embodiment is not limited here.

[0086] Among them, the partition 140 is provided with a through hole 142 for air circulation, and an air channel is formed in the channel separated by the partition 140 and the bottom wall of the terminal body 100. The refrigerator 310 and the fan 320 are turned on, and the fan 320 allows the cold air generated by the cold end of the refrigerator 310 to pass through the through hole 142 evenly into the interior of the terminal body 100, thereby increasing the air circulation rate inside the terminal body 100. Under the action of the exhaust fan 220, the heat dissipation inside the terminal body 100 is accelerated, and the temperature inside the terminal body 100 is reduced.

[0087] It is understandable that the number and layout of the through holes 142 are only given for example, and can be specifically set according to actual needs, and this embodiment is not limited thereto.

[0088] See also Figure 2 and Figure 5 In the embodiment of the present application, it also includes a moving component 700; the moving component 700 includes at least one hydraulic rod 710, at least two universal wheels 720 and a connecting plate 730, the hydraulic rod 710 is embedded in the bottom of the terminal body 100, and the moving end of the hydraulic rod 710 passes through the bottom of the terminal body 100 and is fixedly connected to one end of the connecting plate 730 facing the terminal body 100; the universal wheel 720 is rotatably connected to the end of the connecting plate 730 away from the terminal body 100 through a rotating shaft.

[0089] In the present application, in order to facilitate the movement of the terminal body 100, a moving component 700 is set at the bottom of the terminal body 100, wherein a hydraulic rod 710 is embedded in the bottom of the terminal body 100, and the extension and retraction of the hydraulic rod 710 is adjusted to drive the movement of the connecting plate 730.

[0090] It can be understood that the universal wheel 720 is rotatably connected to the end of the connecting plate 730 away from the terminal body 100 through a rotating shaft. That is to say, the extension of the hydraulic rod 710 drives the connecting plate 730 to move toward the ground, thereby controlling the universal wheel 720 to contact the ground. The movement of the universal wheel 720 on the ground drives the terminal body 100 to move, thereby improving the convenience of use.

[0091] After the terminal body 100 is moved to a suitable position, the hydraulic rod 710 is adjusted to contract to drive the connecting plate 730 to move away from the ground, thereby controlling the universal wheel 720 to separate from the ground, thereby fixing the terminal body 100.

[0092] See also Figure 1 In the embodiment of the present application, at least three supporting blocks 150 are disposed at the bottom of the terminal body 100 .

[0093] Among them, a support block 150 is set at the bottom of the terminal body 100. The number and layout of the support blocks 150 are only given for example. The specific layout can be set according to actual needs. The purpose is to ensure the placement stability of the terminal body 100. This embodiment is not limited here.

[0094] In a specific implementation, the support block 150 can be fixed to the bottom of the terminal body 100 by welding, and the support block 150 and the terminal body 100 can also be connected by other means, so as to achieve a stable support of the terminal body 100 by the support block 150.

[0095] That is, after the terminal body 100 is moved to the corresponding position via the universal wheels 720 , the hydraulic rod 710 is adjusted to contract so that the universal wheels are separated from the ground and the support blocks 150 are in contact with the ground, thereby achieving fixed placement of the terminal body 100 .

[0096] See also Figure 1 In the embodiment of the present application, an inspection door 160 is rotatably connected to the back side of the terminal body 100 .

[0097] In the present application, the back side of the terminal body 100 is rotatably connected to an inspection door 160 with a handle. When in use, the staff can open the inspection door 160 through the handle, and then drive the universal wheel 720 to rise and fall by adjusting the hydraulic rod 710. At the same time, the provision of the inspection door 160 also facilitates the staff to inspect the electrical components inside the terminal body 100, thereby improving the practicality and service life of the terminal.

[0098] In summary, the terminal provided by the present application dissipates heat inside the terminal body 100 by disposing a circular tube 210 inside the terminal body 100, and then injecting water into the circular tube 210 to perform water cooling on the inside of the terminal body 100, and then the heat is discharged to the outside of the terminal body 100 through the exhaust fan 220 on the top of the terminal body 100. At the same time, a refrigeration component 300 is disposed inside the terminal body 100. The refrigeration component 300 includes a refrigerator 310 and at least one fan 320. Starting the refrigerator 310 can cool the inside of the terminal body 100, and then the fan 320 on the side wall of the terminal body 100 is used to circulate the cold air generated by the cold end of the refrigerator 310 through the air, thereby achieving efficient heat dissipation of the terminal and improving the service life and practicality of the terminal.
