Computer heat dissipation device controlled by APP

The invention provides a computer heat dissipation device controlled by APP. A cold accumulation liquid storage cavity and an air feeding and exhausting channel arranged on one side of the cold accumulation liquid storage cavity are in an integrated structure; a fixed module is arranged on the other side of the cold accumulation liquid storage cavity; the cold accumulation liquid storage cavity is internally filled with cold accumulation liquid; the two ends of a circulating pipeline are communicated with the cold accumulation liquid storage cavity respectively; the circulating pipeline is provided with a circulating pump and a refrigerating machine; the air feeding and exhausting channel is internally provided with a fan, a noise reduction pore plate and a dustproof net; the cold accumulation liquid storage cavity is provided with a plurality of refrigerating channels; the refrigerating channels are communicated with the air feeding and exhausting channel; an APP signal receiving module is electrically connected with a single chip microcomputer; and the single chip microcomputer is electrically connected with the circulating pump, the refrigerating machine and the fan respectively. The computer heat dissipation device controlled by the APP has the beneficial effects that the computer heat dissipation device is convenient to turn on and off, can rapidly dissipate heat and has a wide applicable range.
