Embodiment 1

[0027] The utility model relates to a bionic liquid-absorbing core with a spider web structure, which is a groove structure formed along a spider web-shaped path on the inner side wall of an evaporation plate base. Boss areas are arranged around the evaporating plate for welding with the condensing plate to form a closed cavity.

[0028] The cobweb-shaped path is concave, and the concave part forms a groove structure.

[0029] The cobweb-shaped path includes a ring-shaped auxiliary path and multiple main paths; multiple main paths converge at the center of the evaporating plate and diverge to the surroundings of the evaporating plate, and the annular auxiliary path diverges from the middle of the evaporating plate in a spiral circle, and is connected with each main path. The paths intersect multiple times, so that the main path and the ring-shaped auxiliary path form a spider web; multiple main paths converge at the central point, and the main path and the ring-shaped auxiliar...

Embodiment 2

[0032] In this embodiment, along the helical divergence direction of the circular secondary path, the circular secondary path segments between adjacent nodes are arc-shaped, and the arc-shaped transitions between adjacent circular secondary path segments are smooth.

[0033] The parts not mentioned in this embodiment are the same as those in Embodiment 1.

[0034] The depth of the grooves is 0.4mm and the width of the spider web path is 0.5mm.

Embodiment 3

[0036] In this embodiment, the cobweb-shaped path is convex, and a groove structure is formed between the convex parts.

[0037] The absorbent core adopts sintered powder porous structure.

[0038] The parts not mentioned in this embodiment are the same as those in Embodiment 1.

[0039] The depth of the grooves is 0.3 mm and the width of the spider web path is 0.6 mm.

Abstract

The invention relates to a bionic liquid absorption core with a cobweb structure, which is a groove type structure which is positioned on the inner side wall of an evaporation plate and is formed according to a cobweb-shaped path. The cobweb-shaped path is concave, and the groove type structure is formed by the concave part. The cobweb-shaped path is convex, and the groove type structure is surrounded among the convex parts. The invention also relates to a soaking plate using the bionic liquid absorption core with a cobweb structure. The soaking plate comprises an evaporation plate and a condensation plate which are matched with each other; the evaporation plate and the condensation plate are connected and sealed with each other to form a closed cavity; the interior of the closed cavity is vacuumized, and is filled with a liquid working medium; the interior of the closed cavity is of a support pillar structure; and the bionic liquid absorption core is arranged on the inner side wall of the evaporation plate. The liquid working medium can be transported efficiently, the heat dissipation efficiency is high, and the liquid absorption core belongs to the field of soaking plates.

Description

technical field [0001] The invention relates to the field of soaking plates, in particular to a bionic liquid-absorbing core with a spider web structure and a soaking plate applied thereto. Background technique [0002] In recent years, the optoelectronic industry represented by microelectronic chips and semiconductor light-emitting elements has gradually developed in the direction of high performance and high integration. The heating power of electronic components is gradually increased and the effective heat dissipation space is gradually reduced, and the heat dissipation problem is gradually highlighted. The internal heat of electronic components accumulates, and the temperature of the working environment continues to rise, causing the performance of electronic components to be greatly reduced. At the same time, the electrical stress or thermal stress caused by the temperature rise may also lead to a decrease in the reliability of electronic components and a greatly short...
