[0002] With the rapid development of mobile communication technology, the number of users of wireless communication equipment has doubled year by year. A large number of computers, network servers, switches, etc. are stored in the cabinet. These devices may generate electromagnetic waves to propagate outward during operation. The shielded computer room is mainly used to prevent the signal leakage of computers, network servers, switches and communication electronic equipment during operation and to prevent the above equipment from being interfered by external electromagnetic waves during operation to ensure normal operation.

[0003] However, electronic equipment tends to generate heat when working. Excessive temperature can easily cause electronic equipment failure, posing a safety hazard. Some existing shielded machine rooms will install air conditioners for cooling, but the uneven air flow distribution of the air conditioner leads to uneven heat dissipation. As a result, the electronic equipment close to the air conditioner can get normal heat dissipation, while the electronic equipment far from the air conditioner has poor heat dissipation effect.

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] See also Figures 1 to 6 As shown, a shielded computer room with heat dissipation function includes a computer room body 1, a shielding door 11, a top plate 2, a bottom plate 3, an air inlet 6, an exhaust assembly 8 and a refrigeration assembly 9. The computer room body 1 is a house structure with a hollow interior and an electromagnetic shielding function, and is used to store electronic equipment, such as computers, network servers, switches, etc. The shielding door 11 is arranged on one side of the computer room body 1, and is used to open or close the computer room body 1. The top plate 2 is fixedly arranged at the upper part of the interior of the computer room body 1, and is combined with the top wall and side walls of the computer room body 1 to form an exhaust chamber 4, which is used to discharge the hot air generated by the electronic equipment in the computer room body 1. The bottom plate 3 is fixedly arranged at the lower part of the interior of the computer room body 1, and is combined with the bottom wall and side walls of the computer room body 1 to form an air inlet chamber 5. The air inlet 6 is arranged on one side of the air inlet chamber 5, and is used to provide cool natural air from the outside to the interior of the computer room body 1.

[0029] In this embodiment, multiple vents 7 are evenly distributed on the top plate 2 and the bottom plate 3 for connecting the air inlet chamber 5 and the exhaust chamber 4 with the interior of the machine room body 1. The multiple vents 7 arranged on the bottom plate 3 can make the air in the air inlet chamber 5 flow evenly to the machine room body 1, and the multiple vents 7 arranged on the top plate 2 can make the hot air inside the machine room body 1 be evenly discharged from the exhaust chamber 4. Preferably, the multiple vents 7 are evenly distributed on the top plate 2 and the bottom plate 3 in a rectangular array to make the air circulation more uniform and further improve the heat dissipation effect. Furthermore, an electromagnetic shielding net 71 is fixed in each vent 7, wherein the electromagnetic shielding net 71 adopts the beryllium copper wire mesh in the prior art. The electromagnetic shielding net 71 not only ensures the internal heat dissipation of the machine room body 1, but also performs electromagnetic shielding on the electronic equipment, thereby improving the electromagnetic shielding effect of the machine room body 1.

[0030] The exhaust components 8 are two components fixed on opposite sides of the exhaust chamber 4, which are used to quickly extract the air in the exhaust chamber 4 and discharge it to the outside of the computer room body 1. The two exhaust components 8 each include an exhaust channel 81 and an exhaust fan 82. One end of the exhaust channel 81 is connected to the exhaust chamber 4, and the exhaust fan 82 is arranged at the other end of the exhaust channel 81 and is connected to the exhaust channel 81. By setting the exhaust fan 82, the air in the exhaust chamber 4 can be quickly extracted. At the same time, by arranging the exhaust components 8 on opposite sides of the exhaust chamber 4, the air in the exhaust chamber 4 can be made to flow out as evenly as possible to avoid uneven heat dissipation inside the computer room body 1 caused by unilateral outflow.

[0031] The refrigeration assembly 9 is fixedly mounted on one side of the air inlet chamber 5, and is used to provide low temperature to the air inlet chamber 5. The refrigeration assembly 9 includes a cooling pipe 91 and a water chiller 92 for providing cooling liquid to the cooling pipe 91, wherein the cooling machine is a prior art that can cool water or cooling liquid, and will not be described in detail here. The cooling pipe 91 passes through the side wall of the machine room body 1 and is arranged inside the air inlet chamber 5. In this embodiment, one end of the cooling pipe 91 is a water outlet end, which is connected to the water chiller 92. After passing through the side wall of the machine room body 1, the cooling pipe 91 is laid in an S shape inside the air inlet chamber 5 to fully cool the air inlet chamber 5, and then the other end of the cooling pipe 91 passes through the side wall of the machine room body 1 and is connected to the water chiller 92, that is, the cooling liquid in the cooling pipe 91 forms a closed loop with the water chiller 92, and the cooling of the water chiller 92 is used to provide a cold source for the air inlet chamber 5.

[0032] In this embodiment, there are multiple air inlets 6, and each air inlet 6 is provided with a filter assembly 61 for filtering dust in the air to prevent dust from entering the interior of the machine room body 1 from the air inlet chamber 5 and contaminating the electronic equipment inside the machine room body 1. The filter assembly 61 includes an electromagnetic shielding cover 611, a protective net 612, and a dust filter 613. The electromagnetic shielding cover 611 is a beryllium copper wire mesh in the prior art, which is fixed on the side of the air inlet 6 close to the air inlet chamber 5 to further improve the electromagnetic shielding effect of the machine room body 1. The protective net 612 is fixed on the other side of the air inlet chamber 5, that is, the protective net 612 is fixed on the outside of the air inlet 6. The dust filter 613 is filled and arranged between the electromagnetic shielding cover 611 and the protective net 612 to prevent external dust from entering. The protective net 612 is used to protect the dust filter 613.

[0033] In this embodiment, one end of the protective net 612 in the length direction is hinged to the side wall of the computer room body 1, and the other end of the protective net 612 is screwed to the side wall of the computer room body 1 through the ingot nut 614. By setting the ingot nut 614, the staff can easily remove the protective net 612 without the help of other tools when opening the protective net 612, which is convenient and quick.

[0034] When the utility model is implemented, the staff first starts the refrigeration component 9. The cooling pipe 91 of the refrigeration component 9 is cooled to reduce the temperature inside the air inlet chamber 5. At the same time, the exhaust component 8 is turned on, and the exhaust fan 82 of the exhaust component 8 is turned on to form a negative pressure in the exhaust chamber 4. Therefore, the heat generated by the electronic equipment in the computer room body 1 is evenly discharged into the exhaust chamber 4 through the multiple air vents 7 on the top plate 2. At this time, a slight negative pressure is generated in the computer room body 1, which drives the cold air cooled by the cooling pipe 91 in the air inlet chamber 5 to be evenly discharged into the computer room body 1 to cool the electronic equipment.

[0035] It should be noted that, in the present invention, since the air intake chamber 5 for generating cold air is arranged below the machine room body 1, and the exhaust chamber 4 is arranged above the machine room body 1, and according to the principle that cold air descends and hot air rises, the inside of the machine room body 1 can be gradually cooled down through the exhaust assembly 8. Furthermore, according to the principle of pre-condensation of water vapor, the cold air is prevented from being blown directly to the upper part of the machine room body 1, and condensed into water droplets after meeting the hot and humid gas in the air, which may cause the water droplets to be blown directly onto the electronic equipment, causing the hidden danger of damage to the electronic equipment.

[0036] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
