The invention discloses a spray type cabinet heat dissipation
system. The
system comprises a spraying
phase change heat absorption module, a
liquid storage tank, a pre-cooling module, a liquid
circulating pump and insulating cooling liquid, wherein the spraying
phase change heat absorption module, the liquid
circulating pump, the
liquid storage tank and the pre-cooling module form a
phase change heat dissipation circulating loop, the insulating cooling liquid flows in the phase change heat dissipation circulating loop, and the spraying phase change heat absorption module comprises a liquid inlet
pipe, a controllable spraying device, a
steam condensation module, a liquid
recovery module and a liquid return header
pipe; the
steam condensation module is positioned above a
server in the cabinet and comprises a
steam condensation surface, a cold source channel and a
cooling chamber; functional condensation units are orthohexagnal, the centers of the functional condensation units protrude, and the peripheries of the functional condensation units are low. According to the invention, the liquid
recovery efficiency is effectively improved; the controllable spraying device, the steam condensation module and the pre-cooling module are integrated in the cabinet, the structure is compact, and modular production is easy.
