The invention belongs to the field of the heat dissipation of electronic devices and specifically discloses a multi-
branch jet flow microchannel
chip liquid cooling and heat radiating device which comprises a cooling liquid inlet
pipe, a cooling liquid outlet
pipe and a multi-
branch jet flow microchannel cavity. The cooling liquid inlet
pipe and the cooling liquid outlet pipe are installed on themulti-
branch jet flow microchannel cavity which is a compact
whole body formed by stacking and bonding an inlet and outlet layer, a
recovery layer, a
recovery hole layer, a jet
nozzle layer and a microchannel layer in order, the cooling liquid inlet pipe is arranged on the inlet and outlet layer and communicates with the jet
nozzle layer, cooling liquid enters into the microchannel layer via the jet
nozzle layer, the cooling liquid outlet pipe is arranged on the inlet and outlet layer and communicates with the
recovery layer, and the heat-absorbing cooling liquid is discharged out of the cooling liquid outlet pipe from the microchannel layer via the jet nozzle layer, the recovery hole layer and the recovery layer. According to the multi-branch jet flow microchannel
chip liquid cooling andheat radiating device, the uniformity of the temperature of a
chip can be improved, the heat dissipation performance is improved, and the heat dissipation problems of a
high heat flux density chip anda heat generating electronic device can be solved.
