The invention belongs to the field of heat dissipation of phase-change electronic devices, and specifically discloses a flat plate evaporator suitable for pouring capillary cores, which includes a heating surface, a shell, a capillary core, a liquid inlet and a gas outlet, wherein: the heating The surface of the lower side of the surface is smooth, and the upper side is provided with a plurality of heat conduction ribs at intervals. The gaps between the heat conduction ribs form steam channels; Circumferential slot; the capillary core is formed by pouring pouring material into the cavity. After the pouring is completed, the capillary core is in close contact with the upper side of the heat conduction rib, and the circumferential slot is submerged, and the cavity The part of the body without capillary cores is a compensation chamber; the liquid inlet communicates with the compensation chamber, and the gas outlet communicates with the steam channel. The invention realizes good heat transfer performance, sealing performance and reliability of the evaporator, and can solve the problems of heat dissipation of large heat sources, multiple heat sources at intervals and heat dissipation of heterogeneous heat sources.
Description
technical field [0001] The invention belongs to the field of heat dissipation of phase-change electronic devices, and more specifically relates to a flat plate evaporator suitable for pouring capillary cores. Background technique [0002] With the power increase and scene update of electronic device heat dissipation, the heat dissipation technology is also constantly adjusted and optimized accordingly. In the phase change heat device, the loop heat pipe is widely used in the fields of military industry, aerospace and electronic product heat dissipation. It relies on the phase change to drive the internal working fluid flow of the system to achieve directional heat transfer. The loop heat pipe has great heat dissipation potential, and at the same time has the advantages of no moving parts, low noise during operation, long pipeline and flexible layout, and anti-gravity operation. [0003] Generally, the process of heat pipe or loop heat pipe used for heat dissipation of elect...
