Abstract

The invention relates to a micro cooler capable of condensing steam into drops and automatically collecting water. The micro cooler adopts a three-layer structure of an upper glass plate, a middle silicon slice and a lower glass plate, wherein the upper glass plate and the middle silicon slice are bonded to form a condenser, an evaporator, a liquid pipe and a steam pipe; the lower glass plate and the middle silicon slice are bonded to form a high-temperature chip heat transferring zone and a cooling water pipe. The micro cooler disclosed by the invention adopts a special truncated pyramid-hemisphere type micron-nanometer double-layer heterostructure to modify a silicon condensation surface, so that drop-shaped liquid drops can be quickly formed by the condensation of steam in the condenser, autonomously concentrated close to the liquid pipe, and sent to the evaporator to absorb heat by a large capillary driving force provided by the liquid pipe consisting of a plurality of capillary tubes. The invention further relates to a manufacturing method of the micro cooler. The micro cooler disclosed by the invention has the advantages of being novel in structure, small in size, light in weight, good in stability, and excellent in refrigeration performance.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a dropwise condensation and self-collecting microrefrigerator and a manufacturing method thereof. Background technique [0002] The existing chip-level phase-change micro-device design scheme mainly adopts the micro-capillary pump suction loop scheme. The micro-refrigerator produced by this scheme is mainly composed of an evaporator, a condenser, a steam pipe, a liquid pipe, a liquid storage tank and a filling area. When the micro-cooler is working, the liquid first evaporates into steam in the evaporator, taking away the heat of the evaporator, the steam flows to the condenser through the steam pipe, condenses into liquid in the condenser, and releases heat to the external environment, and the liquid flows back through the liquid pipe to The evaporator completes a cycle. The fill zone is used to inject liquid, the reservoir is used to store excess liquid, and the steam g...
