Description

Fanless cabinet heat dissipation device

The present invention relates to a fanless cabinet heat dissipation device, in particular, it can use the hollow flow channel on one side of the cabinet group to naturally form a chimney effect, so as to increase the convection of the airflow, and provide a light, efficient, and double rapid heat dissipation device.

According to the current traditional heat dissipation cabinet (1), it is provided with a cabinet body (10), which is respectively provided with a top cooling hole slot (11) and a peripheral cooling hole slot (12) on the top and the periphery of the cabinet body (10) , And in the cabinet body (10) are provided with several interlayer plates (13), so that the top and the periphery are respectively provided with top heat dissipation hole slots (11) and peripheral heat dissipation hole slots (12) to communicate with the outside to form a cabinet body (1) The heat dissipation function, but it still has the following deficiencies: 1. Although the cabinet body (1) is provided with heat dissipation holes (11, 12), but the heat is concentrated inside, which cannot effectively dissipate heat, and a cooling fan must be installed (The picture is not drawn) to increase its convection to improve its heat dissipation. Once the wind breaks down, effective heat dissipation cannot be formed. In addition to the appearance of audio and video and the increase in volume costs, it also increases the failure rate and maintenance inconvenience; 2. In addition, the interlayer board (13) inside the cabinet (1) is a dense laminate, which blocks the convection of the internal heat source and causes the wires to be squeezed between the interlayer boards (13), so that there is no proper storage space for the wires. However, it occupies more space, in addition to affecting the overall outlook and cost, it also loses the lack of lightness and beauty, which is not in line with economic benefits.

In view of the shortcomings of the above-mentioned knowledge, there is a need for improvement. The inventor has exhausted his mind to study and design, and uphold the creative spirit of perseverance. After many discussions and trials, and fully perfected ideas and improvements, the inventors have introduced A fanless cabinet with independent heat dissipation that can utilize the convection and enhanced convection design with the chimney.

In view of the shortcomings of the traditional intercooler tube making, the inventor has thought and created the idea, so he designed it with many years of experience, and after various discussions and trial samples, With many modifications and improvements, the present invention was introduced. In view of this, the present inventors rely on long-term research on the relevant plasma polishing industry and the concept of thorough understanding, and then design with many years of experience, and after various discussions and trial samples The test is to launch the present invention.

The main purpose of the present invention is to provide a fanless cabinet heat sink, especially the cabinet body of the cabinet group. The first cabinet is provided with a closed hollow chamber, and a hollow second cabinet is provided on one side, so that the second cabinet One end of the cabinet is formed with an independent external flow channel inlet and one end with an independent external flow channel outlet, so that the first cabinet and the second cabinet are connected and adjacent to each other by the cabinet side plate of the first cabinet, so that the load is carried by the cabinet partition with airflow cooling holes. The device is fixed on the inner side of the first cabinet to form an internal compartment, and a first heat sink is arranged inside the cabinet side plate of the first cabinet, and the inside of the second cabinet corresponds to the first heat sink inside the cabinet side plate of the first cabinet The second heat sink is connected to form a heat conduction effect, so that the hot air in the first cabinet will follow the baffle of the cabinet partition and the airflow heat dissipation holes upward, and the heat dissipation device will conduct the heat to the second cabinet through heat dissipation. The hot air can rise along the hollow flow channel to form a chimney effect. The air flow caused by the hot air radiating through the independent external flow channel outlet, and at the same time, the outdoor air is drawn into the population through the independent external flow channel to fill in, so that air convection and heat dissipation can be quickly caused The effect is to enhance the convection design with the chimney convection effect, and to improve the traditional cabinet. The heat dissipation fan must cause the air convection to discharge the hot air. It is unnecessary to increase the material cost and affect the appearance of the exterior. It can also effectively save assembly space and Reduce the failure rate, making it a fanless cabinet with independent heat dissipation design and fast heat dissipation.
