Cooling device for server chassis

technical field

The utility model relates to a heat dissipation device of a computer case, in particular to a heat dissipation device inside a computer server case.

Background technique

With the continuous development of manufacturing technology, a revolution of hardware equipment is going on in the computer field. On the one hand, we have higher and higher requirements for computer performance, which requires higher processing power of the CPU. Generally, the higher the processing power of the CPU, the greater the power consumption and the more heat emitted. On the other hand, the computer The profile of the server case is getting smaller and smaller, and its heat dissipation ability is worse, which makes people have high requirements for the cooling device of the computer. To be done. Therefore, the heat dissipation effect is poor, and it cannot meet the requirements of high-power CPU ventilation and heat dissipation.

There are many ways to dissipate heat in the chassis at present. In computer server chassis, the server needs to work for many years. How to guide the hot air in the chassis to reduce the temperature in the chassis and prolong the service life of the server also needs to consider the limited space of the server chassis. factor. Moreover, the operating frequency of the server is not consistent. How to intelligently adjust the fan to adapt to different temperature changes is also a problem that needs to be considered in the design of the current server chassis.

In order to achieve the above-mentioned functions inside the computer mainframe, many additional electronic components are added in the limited space of the computer case, which makes the internal space of the case smaller and more compressed. The electronic components in the computer case operate normally under normal operating temperature, so it is necessary to find another heat dissipation countermeasure to solve the heat dissipation problem of the computer case. However, the space inside the chassis itself is limited, and it is impossible to use natural convection to assist the heat dissipation of each electronic component. Therefore, the existing heat dissipation method is to directly install a heat dissipation structure on each electronic component, such as a heat dissipation fan. The strong airflow directly blows the electronic components, and the heat generated by the electronic components is directly taken away by the air to keep the electronic components working at a normal temperature. Although this heat dissipation method can quickly take the heat away from each electronic component, However, the heat taken away still accumulates inside the computer case, which instead causes a temperature rise effect, which not only fails to solve the original heat dissipation problem, but directly causes direct damage to all electronic components inside the computer case.

Utility model content

In order to solve the internal heat dissipation problem of the server chassis in the prior art, the utility model proposes a heat dissipation device that installs a plurality of fans in the limited space of the chassis to cool down the hard disk and at the same time cool down the electronic components on the motherboard.

Detailed ways

As shown in Figure 1, the hard disk is installed in the front of the server chassis, the main board and power supply are installed in the rear, the middle board is installed between the hard disk and the main board, and the two ends of the middle board are fixed on both sides of the chassis by screws. 1. The fixing plate 2 and the bottom plate 3, there are a plurality of screw holes 6 on the top plate 1, and the fan is fixed by the screws passing through the screw holes 6 and elastic clips. There are four fan fixing holes 4 on the fixing plate 2. The size of the fan fixing holes 4 is designed according to the size of the fan to be installed. Different types of fans can be installed on the same middle plate. Generally, the fans with high power are installed in the middle two. Inside the fan fixing holes, fans with low power are installed in the fan fixing holes on both sides. Base plate 3 is groove shape, and base plate 3 can be fixed on the chassis base plate, also can not be fixed on the case base plate, after fan is stuck in the fan fixing hole, the bottom of fan is inserted in the groove of base plate 3, prevents from shaking. On the bottom plate of the chassis between the middle board and the hard disk, four fan fixing seats 5 are also installed. Seat 5 is used to install spare fan, and each spare fan is all the same size as the corresponding fan on the fixed plate 2, and the spare fan is closely attached to the fan in the fixing hole 4, and the two fans share an air duct for air supply. When the load on the server is high, the heat will be dissipated accordingly. The temperature control module installed in the chassis is used to control the fan speed and the start and stop of the backup fan, so as to ensure the maximum temperature balance in the chassis and achieve the purpose of cooling.

When the fan of the cooling device is working, the heat generated by the hard disk in the front of the chassis is sucked away and sent to the rear of the chassis, and the wind enters from the front of the chassis to cool the hard disk.
