Reaction device for detection chip and reaction system

A reaction device for a detection chip, comprising:

• a chip carrier, configured to place and fix the detection chip;
• an electrical signal control unit, configured to apply an electrical signal to the detection chip so as to drive a heating electrode of the detection chip;
• and
• a support frame,
• wherein the chip carrier comprises a bottom plate, a support portion, a limiting groove, and at least one limiting block;
• the bottom plate comprises a hollow region, and is configured to be in sliding connection with the support frame;
• the support portion is in the hollow region of the bottom plate, and is configured to support the detection chip;
• the limiting groove is around the hollow region of the bottom plate, and is configured to prevent shift of the detection chip;
• the limiting block is on at least one side of the limiting groove, and is configured to prevent warping of the detection chip,
• wherein the chip carrier further comprises a clamp, and
• the clamp is configured to be capable of moving close to or away from the support portion, so as to allow the detection chip to be at a fixed position or a variable position relative to the support portion.
