The invention discloses a double-cavity valveless piezoelectric pump provided with convolution line flow pipes and having a computer CPU water cooling function. The double-cavity valveless piezoelectric pump comprises a hexagon head bolt, a pump cover, an O-shaped ring, a piezoelectric vibrator, an annular ring, a sealing ring, a pump body, a nut, an inlet pipe and an outlet pipe. The pump body is provided with a hexagonal head bolt hole, a sealing ring groove, a second flow channel, an annular ring groove, a pump cavity, a first flow channel, a liquid inlet and a liquid outlet. The pump body and the piezoelectric vibrator are connected in a sealed manner. The bottom of the pump cavity protrudes to form a sector with the central angle of 225 degrees. The piezoelectric pump utilizes the piezoelectric vibrator to generate volume change of the pump cavity so as to realize directional conveying of fluid; the two convolution line flow pipes and the sector-shaped pump cavity are arranged, so that the pump-out amount is increased; the piezoelectric pump has the advantages of small size, low power consumption, no electromagnetic interference, simple structure and the like; and the piezoelectric pump has the wide market prospects in the fields of computer chip cooling and the like.

Description

technical field [0001] The invention relates to a double-cavity valveless piezoelectric pump with a swirl flow tube and a computer CPU water cooling function, which belongs to the field of fluid machinery. Background technique [0002] In order to meet the needs of CPU heat dissipation, the macro pipeline water cooling system plays an important role in chip heat dissipation. The technical content of macroscopic pipeline water cooling is relatively low, and the processing of heat dissipation devices is relatively simple, which can be accepted by most people. Its outstanding advantages are efficient heat dissipation and low noise, but heat dissipation devices are also prone to frost and water leakage. . Traditional water cooling also has many deficiencies. For example, the water pressure of the electromagnetic centrifugal pump is low. If the thickness of the loop channel becomes thinner, the flow of cooling liquid will be limited. A small amount of penetration will occur when...
