A chip heat sink for a chip and a nucleic acid extraction device, where the chip has a channel for conveying a fluid, and on/off of the channel is controlled by an solenoid valve, the chip heat sink includes: a substrate, where the substrate has a first surface for placing the chip, and the first surface is provided with a first accommodating groove for accommodating an electromagnet; and a heat dissipation structure on the substrate and for dissipating heat from the electromagnet.

Chip heat sink and nucleic acid extraction device

A control valve structure, a using method thereof, a microfluidic chip, and a nucleic acid extraction device. The control valve structure includes: a cover plate layer, a first channel layer, a first adhesive layer, a second channel layer, at least one valve core, and at least one elastic film. When the valve core is embedded in the first limiting hole, the elastic film seals the first limiting hole, and the second limiting hole, the first through hole and the liquid outlet channel form a sample liquid flow channel; and when the valve core is embedded in the second limiting hole, the elastic film seals the second limiting hole so as to block the sample liquid flow channel.
