AI Technical Summary
Existing cold plate heat dissipation testing fixtures have a relatively fixed and simple structure, making it impossible to change the size of the grippers according to the specifications and thickness of the cold plate. This limits their application range, and thermal expansion and deformation can affect the test results.
A cold plate heat dissipation testing fixture was designed, which includes a tooling plate, mounting groove, connecting bolts, F-type clamps, a backing plate, threaded holes, and fixing holes. The mounting groove and bolts allow for the replacement of F-type clamps of different sizes according to the thickness of the cold plate, and the backing plate prevents the heat sink from deforming, thus achieving a stable installation.
It enables flexible adjustment of the gripper size according to the thickness of the cold plate, preventing the hot plate from expanding and deforming, ensuring the accuracy of the test results and the wide applicability of the equipment.
