Abstract

The invention relates to a heat radiation device and especially relates to a circuit board air-cooled heat radiation device. The circuit board air-cooled heat radiation device comprises a cabinet, fans and heat-conducting plates. The cabinet is internally provided with circuit boards. One end of the cabinet is provided with a heat radiation chamber. A separator plate is arranged between the cabinet and the heat radiation chamber. The separator plate is provided with heat radiation holes and insert holes, wherein the heat radiation holes and the insert holes enable the cabinet and the heat radiation chamber to be communicated. The heat radiation chamber is provided with air inlets and air outlets. The fans are arranged in the air outlets respectively. Each heat-conducting plate comprises aheat-conducting area and a radiating area. The heat-conducting area and the radiating area are in an overall structure. The heat-conducting areas are fixedly arranged on the circuit boards and make contact with high-power heat radiation components; the radiating areas are arranged at the outer sides of the circuit boards, and are away from the circuit boards; and the radiating areas pass through the insert holes and are arranged in the heat radiation chamber. By prolonging the heat-conducting plates to form independent heat radiation channels, the device helps to realize centralized air cooling; the cabinet is compact in structure and can install more circuit boards under the condition of same size; and the device is better in heat radiation effect and is not easy to accumulate dusts.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a circuit board air-cooled heat dissipation device. Background technique [0002] With the advancement of production technology, the volume of the control box of some CNC equipment is getting smaller and smaller, and it is developing towards thinner and lighter. Due to the shrinking space and limited installation space, the heat generated by the components accumulates and is difficult to dissipate, which is likely to cause local overheating and damage. Ventilation and cooling are required, but the dust in the airflow is likely to have a negative impact on the components and cause the heat dissipation effect to deteriorate. [0003] For example, Chinese patent CN105960154A discloses a circuit board air-cooling adjustment device, including a fan and a fixing seat, the fixing seat is arranged above the fan, and a through hole is arranged in the fixing seat, and a through hole is arranged...
