The flow chamber and the lower flow chamber are provided with multiple jet holes on the partition. The upper end of the upper flow chamber is installed with a cover plate, which is installed with an inlet connected to the upper flow chamber. The lower end of the lower flow chamber is installed with a microfluidic base plate, which is distributed with multiple triangular bosses. The clamping mechanism includes a rotating handle, a swivel, and a bearing. The rotating handle is screwed to the swivel, which is connected to the lower end of the rotating handle. The swivel is connected to the upper cover through a thread, and the bearing is set between the swivel and the test cover frame.

After the upper cover is re-closed, the rotating ring is rotated to apply a clamping force to the chip to fix the chip, and the moving length of the limiting member in the limiting groove is adjusted by inserting the adjusting pins into different sockets, and then the rotation angle of the rotating ring is adjusted, thereby adjusting the degree of clamping of the rotating ring on the chip; a preliminary experiment is carried out before the formal test, and the adjusting pins are inserted into several sockets in order of the moving length of the limiting member relative to the limiting groove from small to large, so that the clamping force applied by the rotating ring on the chip increases successively, and the most suitable socket can be selected through debugging, so that the rotating ring can be rotated to a fixed angle through the limiting effect of the adjusting pin in the formal batch testing work, thereby ensuring that the clamping force of the fixed chip is the same each time and improving stability.

The heat dissipation fan accelerates the air flow and thus improves the efficiency of heat exchange between the air and the heat dissipation connection block, thereby dissipating the heat of the chip.
