technical field

The utility model relates to the technical field of computer hardware, in particular to a computer case with heat dissipation and dustproof functions.

Background technique

In order to enhance its internal heat dissipation, the chassis of the existing computer is provided with an air exhaust port on the side plate or other parts of the chassis, and an exhaust fan is arranged at the position of the air exhaust outlet. To cool down, some of these exhaust fans use independent fans, and some directly use the built-in fan of the power supply. However, the existing chassis is not equipped with an air intake device for automatically and quickly sucking the cold air from the outside into the chassis, and it is impossible to realize the cold air from the outside. The rapid air convection between the chassis and the chassis, therefore, the heat dissipation effect is poor, and the existing chassis does not have a dust-proof device, and the air dust is easy to enter the chassis. When the dust accumulates to a certain amount, it will affect the normal operation of the computer. Reduce the life of each component in the chassis, and then cause the computer to go black or shut down, affect the normal use of the computer by the user, and even lose important data, causing irreparable losses.

Utility model content

The technical solution adopted by the utility model is: including a box body, the box body includes a rear panel, a left side wall panel, and a right side wall panel, an air outlet is arranged on the upper part of the rear panel, and a The exhaust fan is provided with an air inlet in the middle part of the left side wall or the middle part of the right side wall, and an air inlet fan is arranged in the box facing the position of the air inlet, and the air outlet and the air inlet are covered There is an air filter.

In order to achieve a better air dust filtering effect, the air filter is rectangular as a whole. The air filter is composed of an electrostatic adsorption net in the middle and a rubber rectangular frame around it. The edge of the electrostatic adsorption net is fixed to the side wall of the hollow part of the rubber rectangular frame. connect.

In order to produce a good electrostatic adsorption effect, the electrostatic adsorption net is made of chemical fiber materials.

In order to facilitate the installation and disassembly of the air filter, the back surface of the rubber rectangular frame is provided with an adhesive material layer.

In order to make the speed of the intake fan and exhaust fan automatically increase or decrease with the temperature inside the cabinet to achieve a better heat dissipation effect, a temperature sensor and a fan speed controller are installed in the cabinet, and the fan speed controller is connected with the temperature sensor, the intake fan, Exhaust fan electrical connection.

In order to improve the flow and velocity of air, both the intake fan and the exhaust fan are turbofans.

The positive effects of the utility model are: the utility model has simple structure, reasonable design, stable performance, and well solves two major problems of heat dissipation and dust prevention. The air inlet and fan are added to quickly suck the cool air outside the chassis into the chassis to directly cool down the electronic components in the chassis, speed up the air circulation in the box, improve the heat dissipation efficiency, and ensure the normal speed of the computer. The mouth is covered with an air filter to prevent the dust in the air from entering the chassis, avoiding the components in the chassis from being infringed by dust, thereby prolonging the service life of the hardware in the chassis, and keeping the interior of the chassis clean while effectively dissipating heat. The utility model can automatically adjust the rotating speeds of the intake fan and the exhaust fan according to the difference of the ambient temperature in the case through the cooperation of the temperature sensor, the controller and the cooling fan, so that the temperature control of the case is more intelligent.

Detailed ways

As shown in Figures 1 and 2, the utility model includes a box body 1, and the box body 1 includes a rear panel 3, a left side wall panel 7, and a right side panel 4, and an air outlet 8 is arranged on the top of the rear panel 3. An exhaust fan 9 is arranged in the box body 1 at the position of the air outlet 8, and an air inlet 10 is provided at the middle of the right side wall 4 or an air inlet (not shown) is provided at the middle of the left side wall 7. Only one air inlet can be provided. Because the positions of the air inlet of the left side wall 7 and the air inlet 10 of the right side wall 4 are symmetrical and have the same structure, the air inlet of the left side wall 7 will not be described in detail here. An air inlet fan 11 is arranged in the cabinet 1 facing the air inlet of the left side wall 7 or the air inlet 10 of the right side wall 4 , and an air filter 2 is covered on the air outlet 8 and the air inlet 10 . As shown in Fig. 3 and Fig. 4, the air filter screen 2 is rectangular as a whole. The side walls of the hollow part are fixedly connected. The electrostatic adsorption net 13 is preferably made of chemical fiber material, because chemical fiber material is easy to generate static electricity, and static electricity has a good adsorption effect on dust. The back surface of the rubber rectangular frame 12 is provided with an adhesive material layer 14, and the two air filter screens 2 are respectively bonded to the air inlet 10 and the periphery of the air outlet 8 by the respective adhesive material layers 14 to completely cover the air inlet 10 and the air outlet 8. After using it for a period of time, you can open the box body 1 and use a brush to gently brush off the dust adsorbed on the air filter 2, or gently tear off the old air filter 2, and stick a new air filter 2. It is very easy to replace convenient.
