Background technique

In order to meet consumers' requirements for data processing speed and start executing various programs in the shortest time, the computer system in the industry uses means of increasing chip precision to achieve the development goal of increasing processing speed and multi-tasking computing. The processing speed of the system continues to increase, and the size of the current electronic components is becoming smaller and smaller, followed by the problem of high heat generated by the computer device.

If the heat energy is not dissipated in time, the high temperature will seriously affect the stability and efficiency of the chip or the electronic processing unit during operation, and even shorten the service life of the computer device or cause damage. Therefore, how to quickly discharge the heat energy generated by the computing processing unit has become one of the issues that relevant researchers have focused on in recent years.

In order to solve the heat dissipation problem of computer devices, such as desktop computers or servers, the most commonly used existing heat dissipation method is to install a cooling fan inside the computer device, and directly blow a forced airflow to the electronic components with high heat energy to dissipate heat. Exhaust heat is removed from the computer unit to reduce the internal ambient temperature.

In recent years, a technology of using a wind guide cover to improve heat dissipation efficiency has been developed. The air guide cover is arranged adjacent to or covered on the central processing unit (CPU) or peripheral electronic components, and an air flow channel is formed by the air guide cover, and then matched with the air guide cover arranged on one side of the air guide cover channel The fan, the airflow generated by the fan can pass through the flow channel, and is more directly and concentratedly blown to the electronic components for more efficient heat dissipation.

At present, computer devices such as large servers must adopt dual-chip or even multi-chip processing systems to meet the needs of the computer system to smoothly process and calculate a large amount of information. In order to dissipate heat from multiple chip systems at the same time, an air guide cover with several air outlet channels is disclosed in China Taiwan Patent No. The channels respectively correspond to the chip systems, and an isolator is provided between the air outlet channels to prevent the airflows generated by the fans from influencing each other to form turbulent flow, so as to increase the overall heat dissipation efficiency.

Although the aforementioned patent No. M244718 can simultaneously dissipate heat from multiple chip systems that generate high heat energy, the number of air outlet channels set by the air guide cover is not necessarily applicable to various types of computer devices. If the air guide cover is installed in a computer device with a smaller number of chip systems than the number of air outlet channels, the airflow generated by the fan cannot be blown to the chip system through the air outlet channels, resulting in a waste of resources, and even lower cooling efficiency due to airflow. scattered and reduced.

The cover body is arranged on the casing, and at least two air guide areas are partitioned inside the cover body, and an air port corresponding to the electronic component is respectively provided on one side of the air guide area. The windshield is installed at the position of the tuyere that does not correspond to the electronic component. The side of the windshield opposite to the electronic component has a fool-proof part, and the relative positions of the fool-proof part and the electronic component overlap each other to prevent the windshield from being installed. Set to the corresponding air outlet with electronic components.
