Heat dissipation apparatus and electronic device

A heat dissipation apparatus, comprising:

• a first branch pipeline, capable of accommodating a heat dissipation medium and configured for dissipating heat for a first heating element;
• a second branch pipeline, capable of accommodating the heat dissipation medium and configured for dissipating heat for a second heating element;
• a connection pipeline, two ends of the connection pipeline being connected to the first branch pipeline and the second branch pipeline respectively, including:
• a first pipeline part, two ports of the first pipeline part being respectively connected to a first end of the second branch pipeline and a first end of the first branch pipeline;
• and
• a second pipeline part, a first end of the second pipeline part being connected to a side wall of the first pipeline part, and a second end of the second pipeline part being connected to an output pipeline;
• the output pipeline, connected to the connection pipeline;
• and
• a moving member, movably arranged in the first pipeline part and capable of moving toward the first branch pipeline side or the second branch pipeline side in the first pipeline part to adjust a communication area between the first branch pipeline and the output pipeline and a communication area between the second branch pipeline and the output pipeline;
• wherein:
• a length of a first port of the second pipeline part in a first direction is greater than a length of a second port of the second pipeline part in the first direction;
• and
• a chamber of the second pipeline part is flat, and a height of the second pipeline part in a second direction is smaller than a height of the moving member.
