[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figs. 1-3 In this embodiment: a high-heat-dissipation computer case includes a case body 1. The front, bottom and right side of the case body 1 are respectively provided with a first air inlet 1-1, a second air inlet 1-2 and a third air inlet 1-3. A vertical row of inclined first heat sink 3 and a horizontal row of inclined second heat sink 4 are respectively installed at the first air inlet 1-1 and the third air inlet 1-3. The purpose of setting the first heat sink 3 and the second heat sink 4 is to increase the heat dissipation area of the case body 1 and improve the overall heat dissipation effect of the computer case. A bracket 6 is installed on the inner side of the first air inlet 1-1. Three intake fans 7 are installed on the bracket 6. The function of the intake fans 7 is to draw external air into the interior of the case body 1 from the first air inlet 1-1. When the external air enters from the first air inlet 1-1, it will pass through the first heat sink 3 and carry away some of the heat on the first heat sink 3.
[0024] The top and rear of the chassis body 1 are respectively provided with a first air outlet 1-4 and a second air outlet 1-5. Three first exhaust fans 10 are installed inside the first air outlet 1-4, and one second exhaust fan 11 is installed inside the second air outlet 1-5. The total number of exhaust fans is greater than the total number of intake fans. When all the intake and exhaust fans are started, the air volume of the chassis body 1 will be greater than the air volume of the intake, thus forming a negative pressure inside the chassis body 1. This causes external air to be drawn into the chassis body 1 from the second air inlet 1-2 and the third air inlet 1-3, making the airflow more uniform. This effectively avoids heat dissipation dead zones and keeps the temperature inside the chassis body 1 stable. Moreover, when the external air enters from the third air inlet 1-3, it will pass through the second heat sink 4 and carry away some of the heat on the second heat sink 4.
[0025] The bottom left and right sides of the chassis body 1 are equipped with a pair of strip-shaped support legs 8. The bottom of the chassis body 1 and between the two support legs 8 are equipped with two rows of fourth heat sinks 9. The two rows of fourth heat sinks 9 are located in front of and behind the second air inlet 1-2, respectively. The purpose of setting the fourth heat sinks 9 is to increase the heat dissipation area of the chassis body 1 and improve the overall heat dissipation effect of the computer chassis. When the chassis body is placed on the desktop, the outside air enters from the second air inlet 1-2 and passes through the fourth heat sinks 9, and at the same time, it will carry away some of the heat on the fourth heat sinks 9.
[0026] The chassis body 1 has an opening on the left side, and a removable cover plate 2 is installed at the opening with screws. After removing the cover plate 2, computer components can be installed inside the chassis body 1. The cover plate 2 has a fourth air inlet 2-1, and a horizontally inclined third heat sink 5 is installed at the fourth air inlet 2-1. When a negative pressure is formed inside the chassis body 1, external air can be drawn into the chassis body 1 through the fourth air inlet 2-1. When the external air enters from the fourth air inlet 2-1, it will pass through the third heat sink 5 and carry away some of the heat on the third heat sink 5.
[0027] A first filter 12, a second filter 13, and a third filter 14 are respectively installed on the outer sides of the first air inlet 1-1, the second air inlet 1-2, and the third air inlet 1-3 on the main body of the chassis 1. A fourth filter 15 and a fifth filter 16 are respectively installed on the outer sides of the first air outlet 1-4 and the second air outlet 1-5 on the main body of the chassis 1. A sixth filter 17 is installed on the outer side of the fourth air inlet 2-1 on the cover plate 2. The purpose of setting filters on the outer sides of all air inlets and outlets is to block dust and prevent dust from entering the interior of the main body of the chassis 1 and affecting the heat dissipation of the internal computer components. During the use of this computer chassis, the filters need to be cleaned regularly to avoid clogging and affecting ventilation and heat dissipation.
[0028] The main body 1 of the chassis is made of aluminum alloy or steel, and the cover plate 2 is made of aluminum alloy or steel. The first heat sink 3, the second heat sink 4, the third heat sink 5 and the fourth heat sink 9 are all made of aluminum alloy or steel. Both aluminum alloy and steel have good thermal conductivity. Aluminum alloy is lighter, making the computer chassis easier to carry. Steel has high strength and durability, allowing the computer chassis to bear greater weight and effectively protect the internal components from physical damage. The specific material used depends on the actual situation.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
