[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for a graphics card radiator. Background Art

[0002] As the performance of electronic devices continues to improve, their heating problem has become increasingly prominent. Graphics cards, as one of the important components in computers, will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will affect the performance and service life of the graphics card. Therefore, radiators are used, and during the production process of radiators, their performance needs to be tested, so detection devices are used to detect them.

[0003] When the existing detection device is in use, it lacks the ability to detect the flatness of the radiator, and cannot ensure that the subsequent radiator can be in close and uniform contact with the graphics card, which affects the heat dissipation effect.
