Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The purpose of the present invention is to provide an industrial Internet intelligent terminal chassis and an industrial Internet intelligent terminal to solve the problems existing in the above-mentioned prior art, so that the chassis has a cooling function while still being able to seal and protect electronic components.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The present invention provides an industrial Internet intelligent terminal chassis, such as Figure 1As shown, it includes a chassis 1, a refrigeration device and an air circulation drive device;

[0038] The chassis 1 has a closed cavity, which is used to accommodate electronic components to prevent dust and water from entering and damaging the electronic components.

[0039] like Figure 2 and Figure 3 As shown, the cooling end of the refrigeration device is arranged in a closed cavity; the cooling end releases cold energy and cools the surrounding air to cool down the electronic components; in some embodiments, the refrigeration device includes a refrigeration plate 3, a heat dissipation pipe 6, and a refrigerant circulating in the refrigeration plate 3 and the heat dissipation pipe 6, the refrigerant is a state refrigerant, the refrigeration plate 3 is the refrigeration end, the heat dissipation pipe 6 is the heat dissipation end, the heat dissipation pipe 6 is arranged outside the chassis 1, the refrigerant releases cold energy in the refrigeration plate 3, and absorbs cold energy in the heat dissipation pipe 6. Preferably, as Figure 6 As shown, in order to protect the heat dissipation pipe 6, the heat dissipation pipe 6 is arranged in a heat dissipation box 7, the heat dissipation box 7 is provided with an air outlet 702 at the bottom, an air inlet at the top, the heat dissipation pipe 6 is arranged between the air outlet 702 and the air inlet, and an air extraction device is arranged at the air outlet 702. The air extraction device is used to draw the air outside the heat dissipation box 7 into the heat dissipation box 7 through the air inlet and then draw it out through the air outlet 702 to take away the heat emitted by the heat dissipation pipe 6. The air extraction device is arranged to promote the air circulation efficiency inside the heat dissipation box 7 and ensure the heat dissipation effect of the refrigerant inside the heat dissipation pipe 6. In other embodiments, a filtering device is arranged at the air inlet to filter the air entering the heat dissipation box 7 to prevent impurities in the air from contaminating the heat dissipation pipe 6.

[0040] like Figure 2 and Figure 3 As shown, the air circulation driving device is used to drive the cold air flow at the refrigeration end to achieve cooling of the electronic components, and the air circulation driving device is used to increase the diffusion speed of cold energy. In some embodiments, the air circulation driving device is a fan 4, and the number of fans 4 is preferably two, the fan 4 is arranged on one side of the refrigeration plate 3, the refrigeration plate 3 is hollowed out, and the refrigeration plate 3 is formed by bending and spiraling the refrigeration pipe. The fan 4 blows toward the refrigeration plate 3 and drives the cold air flow at the refrigeration plate 3, thereby achieving the purpose of diffusing the cold air around the electronic components and cooling the electronic components.

[0041] Therefore, the industrial Internet intelligent terminal chassis provided by the present invention adopts a refrigeration device to directly cool the closed cavity in the chassis 1, and drives the cold air flow at the refrigeration end through an air circulation drive device to achieve uniform cooling. The effect of cooling the inner cavity of the chassis 1 can be achieved without opening a heat dissipation port on the chassis 1, and dust and water flow can be effectively prevented from entering and causing damage to electronic components.

[0042] In some embodiments, in order to realize automatic control of the refrigeration device, the following improvements are made:

[0043] like Figure 2 and Figure 8 As shown, the circulation of the refrigerant in the heat pipe 6 and the refrigeration plate 3 is driven by the electric circulation pump 5, and a temperature control switch 2 is also provided in the closed cavity. The temperature control switch 2 has the function of detecting the air temperature. The temperature control switch 2 and the electric circulation pump 5 and the air circulation drive device are all connected in communication to realize the temperature control switch 2 to transmit signals to the electric circulation pump 5 and the air circulation drive device;

[0044] The specific control process is as follows: the first temperature threshold and the second temperature threshold are input into the temperature control switch 2 in advance. When the temperature inside the closed cavity exceeds the first temperature threshold set by the temperature control switch 2 (that is, it proves that the temperature is high), the temperature control switch 2 controls the air circulation drive device and the electric circulation pump 5 to automatically turn on to achieve automatic cooling. When the temperature inside the closed cavity drops to the second temperature threshold set by the temperature control switch 2 (that is, it proves that the temperature is low), the temperature control switch 2 controls the air circulation drive device and the electric circulation pump 5 to automatically turn off to avoid waste of cold energy and achieve energy-saving effect.

[0045] Therefore, the above embodiment realizes the automatic control of the start and stop of the electric circulation pump 5 and the fan 4 by the temperature control switch 2, thereby realizing the function of automatic cooling, without the need for frequent manual control, and better meeting the use requirements.

When the filter screen cylinder 8 rotates, the brush rod 12 can remove impurities attached to the outside of the filter screen cylinder 8 to prevent the impurities from clogging the filter screen cylinder 8 and affecting the ventilation and heat dissipation effect inside the heat dissipation box 7. The liquid inlet and liquid outlet of the hydraulic reduction motor 10 are also connected to the heat dissipation pipe 6, and the refrigerant can drive the hydraulic reduction motor 10 to operate when it flows from the liquid inlet end of the hydraulic reduction motor 10 to the liquid outlet end. When multiple filter screen cylinders 8 are provided, the hydraulic reduction motor 10 drives the multiple filter screen cylinders 8 to rotate through a belt transmission mechanism; and a brush rod 12 is fixedly arranged between two adjacent filter screen cylinders 8, and the brush rod 12 is provided with bristles 1201 on the sides of the two filter screen cylinders 8. Specifically, three filter screen cylinders 8 and two brush rods 12 are arranged in parallel, and the two brush rods 12 are fixedly arranged between two adjacent filter screen cylinders 8 .

[0048] Among them, Figure 5 and Figure 7 As shown, a driving pulley 1001 is installed on the rotating shaft of the hydraulic reduction motor 10, and a driven pulley 801 is provided on one side of the filter screen cylinder 8. The driving pulley 1001 is connected to the three driven pulleys 801 through a transmission belt 11. The liquid inlet and outlet ends of the hydraulic reduction motor 10 are connected to the pipeline of the heat dissipation pipe 6. While the liquid circulates inside the heat dissipation pipe 6, the liquid enters the hydraulic reduction motor 10, driving the hydraulic reduction motor 10 to operate. The hydraulic reduction motor 10 drives the three filter screen cylinders 8 to rotate at a low speed through the transmission belt 11, thereby achieving the effect of cleaning impurities on the outside of the filter screen cylinder 8.

[0049] In the above two embodiments, the hydraulic reduction motor 10 that drives the filter screen cylinder 8 to rotate and the hydraulic motor 9 that drives the impeller 901 to rotate are both driven by the refrigerant in the refrigeration device, which fully utilizes the characteristics of the refrigerant as a fluid, and achieves that after the electric circulating pump 5 in the refrigeration device is turned off, the hydraulic motor 9 and the hydraulic reduction motor 10 also stop working immediately, without the need to set up separate lines to control the hydraulic motor 9 and the hydraulic reduction motor 10.

[0050] More specifically, Figure 6As shown, three air inlet grooves 701 are arranged in sequence on the top of the heat sink 7, and an air inlet top port 7011 is opened on the top of the air inlet groove 701. The three air inlet top ports 7011 form the above-mentioned air inlet, and air outlet side ports 7012 are respectively opened on both sides of the bottom of the air inlet groove 701. The air outlet side ports 7012 are connected to the inside of the heat sink 7, and the filter screen cylinder 8 is located in the air inlet groove 701. The filter screen cylinder 8 is rotatably connected to the air inlet groove 701.
