Description

Technical Field

[0001] The utility model relates to the technical field of heat sink detection, in particular to a heat dissipation performance detection device for continuous detection. Background Art

[0002] Heat sinks are usually made of metal and are heat dissipation devices that improve heat dissipation efficiency by increasing the heat dissipation area. They can quickly dissipate the heat generated by electronic equipment or electrical appliances to the surrounding environment to ensure the normal operation of the equipment and extend its service life. The heat sink needs to be tested for thermal conductivity after production.

[0003] Patent No. CN202122961959.X proposes a thermal detection device for a graphite heat sink. By turning on the dual-axis motor with the cooperation of a dual-axis motor, a guide rod, a fixed rod, a movable seat, fan blades, a disc, a fixed shaft, a connecting rod and a support shaft, the fan blades will rotate, so that the fan blades will blow the heat on the resistance wire and then transfer it to the graphite heat sink. At the same time, the turning on of the dual-axis motor also drives the disc to rotate, and then the movable seat moves on the guide rod, which will drive the fan blades to heat different positions. It can only be loaded manually and can only be detected once, and continuous detection cannot be performed. Therefore, the technical personnel in this field provide a heat dissipation performance detection device for continuous detection to solve the problem that it can only be loaded manually and can only be detected once, and continuous detection cannot be performed.
