[0002] With the rapid development of electronic technology, electronic products are widely used in military and civilian fields, especially high-power electronic products, which have been rapidly promoted. However, the heat generated by electronic products has seriously increased safety risks. Therefore, cooling and heat dissipation have become a hot topic in the industry. In particular, energy-saving, miniaturized, and high-heat-dissipation technologies are the focus of research in countries around the world. To date, a large number of heat dissipation technologies have been applied, some of which have played a very good role. However, facing the problems of high-power electronic products malfunctioning or even burning due to high heat, traditional heat dissipation technologies are clearly no longer suitable for technological development. Therefore, it is urgent to research and design a self-starting heat pipe with high heat dissipation function. After several years of dedicated research, the inventor has systematically innovated an energy-saving, miniaturized, and highly efficient phase-change heat dissipation technology, striving to play a positive role in promoting the application of high-power electronic products.

[0013] The beneficial effects of this invention are: The present invention discloses a high-power micro heat pipe device, which is composed of a boiling vaporizer 2 with high-efficiency boiling vaporization characteristics, a condenser 3 with high-efficiency heat dissipation and cooling phase change liquefaction characteristics, and a capillary liquid transfer block 4 with high-speed liquid transfer function through capillary attraction. A high-temperature heat source contacts the boiling vaporizer 2, causing the working fluid permeated in the copper foam to boil and vaporize efficiently, thus efficiently absorbing heat from the high-temperature heat source. The gaseous working fluid generated by the vaporization phase change diffuses and flows through the upper space of the micro heat pipe shell 1 to the condenser 3, causing the gas to liquefy and transform into a liquid. Due to the innovative technology of the condenser 3 of this invention, the liquid after phase change migrates rapidly under the action of van der Waals forces, improving the liquefaction phase change and accelerating the heat dissipation efficiency. This achieves high efficiency in heat absorption from the high-temperature heat source and heat dissipation in the heat dissipation area, ultimately achieving the goal of high-power heat dissipation. This invention provides an effective solution to the problem of high-temperature generation in high-power electronic products. Attached Figure Description

[0021] The present invention will be further described below with reference to embodiments and accompanying drawings: The present invention discloses a high-power micro heat pipe, comprising a micro heat pipe shell 1, a boiling vaporizer 2, a condenser liquefying device 3, a capillary liquid transfer block 4, a finned radiator 5, a liquid reservoir 6, and a pipe plug 7, the structure of which is as follows: Figure 1 , Figure 2 As shown.

[0022] Example 1

[0023] The micro heat pipe shell 1 of this invention includes a gas-liquid regulating port 1-1, a pipe end port 1-2, a finned opening 1-3, and a vertical wall surface 1-4. The entire micro heat pipe shell 1 is a square-mouthed flat tube. Except for the three openings mentioned above, the rest are sealed. The gas-liquid regulating port 1-1 and the finned opening 1-3 are on opposite wall surfaces, and their structure is as follows: Figure 3 As shown.

[0024] The boiling vaporizer 2 of this invention includes a boiling bed 2-1, a liquid transport bridge 2-2, a liquid transfer connecting piece 2-3, and a liquid storage tank 2-4. The boiling vaporizer 2 is integrally made of foamed copper material with a pore size of 60 ppl-130 ppl. The bottom planes of the boiling bed 2-1, the liquid transport bridge 2-2, and the liquid storage tank 2-4 are on the same plane and have the same width, equal to the width of the inner wall of the micro heat pipe shell 1. Two vertical walls are in close contact with the corresponding inner walls of the vertical walls 1-4 of the micro heat pipe shell 1. The liquid storage tank 2-4 and the liquid transfer connecting piece 2-3 are located at both ends of the boiling vaporizer 2. The liquid storage tank 2-4 is adjacent to the boiling bed 2-1, and the other end of the boiling bed 2-1 is adjacent to the liquid transport bridge 2-2. The other end of the liquid transport bridge 2-2 is adjacent to the liquid transfer connecting piece 2-3. The upper plane of the liquid storage tank 2-4 is higher than the boiling bed 2-1 and the liquid transfer connecting piece 2-3. The infusion bridge 2-2 and the boiling bed 2-1 have closely spaced, equally spaced V-shaped grooves at their upper ends, with the grooves opening upwards. The bottom edge of each V-shaped groove is equidistant from the vertical wall 1-4 of the micro heat pipe shell 1. One end of the bottom of each V-shaped groove connects to the reservoir 2-4, and the other end connects to the infusion bridge 2-2. The inverted V-shaped ridges formed by the closely spaced V-shaped grooves of the boiling bed 2-1 have a tip height consistent with the upper plane of the infusion bridge 2-2. The width of the liquid transfer connecting piece 2-3 is consistent with that of the infusion bridge 2-2, with its bottom plane higher than the bottom plane of the infusion bridge 2-2 and its upper plane lower than the upper plane of the infusion bridge 2-2. One vertical end face of the reservoir 2-4 contacts one vertical inner wall of the micro heat pipe shell 1. The bottom planes of the boiling bed 2-1, infusion bridge 2-2, and reservoir 2-4 are in close contact with the bottom surface of the inner wall of the micro heat pipe shell 1. Its structure is as follows: Figure 4 , Figure 7 As shown.

[0025] The gas-liquid regulating port 1-1 in the micro heat pipe shell 1 provides for the injection or extraction of gas and heat transfer medium inside the pipe. Due to the microporous characteristics of foamed copper, after the working medium is injected into the micro heat pipe shell 1, it is absorbed by the boiling vaporizer 2. When a high-temperature heat source inputs heat to the bottom of the boiling bed 2-1, the working medium in the boiling bed 2-1 undergoes high-temperature boiling phase change vaporization. The closely arranged, equally spaced V-shaped grooves at the upper end of the boiling bed 2-1 facilitate the overflow of vaporized gas, promoting the vaporization phase change of the working medium. The gas after phase change automatically flows to the next stage of the working process. The storage in the boiling vaporizer 2... Liquid reservoir 2-4 and boiling bed 2-1 are homogeneous. When boiling bed 2-1 undergoes a phase change and the density of the liquid working fluid decreases, the liquid working fluid in the delivery bridge 2-2 and the storage reservoir 2-4 automatically seeps into the boiling bed 2-1 due to the loss of balance caused by van der Waals forces, reducing the occurrence of cavitation in the boiling bed 2-1. Conversely, when the density of the working fluid in the storage reservoir 2-4 decreases, the working fluid is similarly drawn from the boiling bed 2-1 for storage. The working fluid liquid in the delivery bridge 2-2 comes from the next stage of the working process and is continuously supplied to the boiling bed 2-1, enabling the boiling bed 2-1 to continuously absorb heat, undergo a phase change, and vaporize.

The liquid receiving end face 4-2 is in close contact with the end face perpendicular to the longitudinal micro-groove 3-3 of the condenser liquefaction unit 3. The two vertical walls are in close contact with the inner walls of the corresponding positions of the vertical walls 1-4 of the micro heat pipe shell 1. The capillary liquid transfer block 4 is made of flexible absorbent cotton material. Its structure is as follows: Figure 6 As shown. The liquid storage bladder 6 is a hexahedron with its bottom plane flush with the condenser 3. One vertical wall surface is in close contact with the other end face perpendicular to the longitudinal microgroove 3-3 in the condenser 3. The upper flat wall surface is higher than the tip of the cone 3-1 in the condenser 3, allowing it to contact the inner wall of the upper end of the micro heat pipe shell 1. Two longitudinal vertical walls are in close contact with the inner walls of the vertical walls 1-4 of the micro heat pipe shell 1 at corresponding positions, with the other wall located at the pipe port 1-2 of the micro heat pipe shell 1. The liquid storage bladder 6 is made of flexible absorbent cotton material. Its structure is as follows: Figure 1 As shown. The boiling vaporizer device Z comprises a boiling vaporizer 2 installed inside one end of a micro heat pipe shell 1. A vertical end face of the liquid reservoir 2-4 in the boiling vaporizer 2 contacts the vertical inner wall of one end of the micro heat pipe shell 1. The bottom surface of the boiling vaporizer 2 is in close contact with the bottom surface of the inner wall of the micro heat pipe shell 1. The liquid transport bridge 2-2 in the boiling vaporizer 2 is tightly inserted into the recess 4-1 in the capillary liquid transfer block 4. The liquid receiving end face 4-2 of the capillary liquid transfer block 4 is in close contact with the vertical end face perpendicular to the longitudinal micro-groove 3-3 in the condenser liquefaction device 3. The bottom plane of the finned radiator 5 is opposite to the bottom plane of the condenser liquefaction device 3. The condenser 3 is installed inside the micro heat pipe shell 1, and the finned radiator 5 is outside the micro heat pipe shell 1. The bottom plane of the finned radiator 5 is on the same plane as the bottom inner wall of the opening of the micro heat pipe shell 1. The other end face of the vertical micro groove 3-3 of the condenser 3 is in close contact with one vertical wall of the liquid storage bladder 6. The other opposite wall of the liquid storage bladder 6 is at the pipe port 1-2 of the micro heat pipe shell 1. The pipe plug 7 covers the pipe port 1-2 of the micro heat pipe shell 1 and seals it. The inverted V-shaped sharp ridge of the boiling bed 2-1 of the boiling vaporizer 2, the upper plane of the liquid transport bridge 2-2, the sharp point of the cone 3-1 of the condenser liquefaction 3, and the capillary liquid transfer block 4 are on the same plane and have the same spatial distance from the inner upper wall of the micro heat pipe shell 1. A miniature heat pipe system is formed by combining a boiling vaporizer 2 with high-efficiency boiling vaporization characteristics, a condenser 3 with high-efficiency heat dissipation and cooling phase change liquefaction characteristics, and a capillary liquid transfer block 4 with high-speed liquid transfer function through capillary attraction. The high-temperature heat source described in the previous working process contacts the boiling vaporizer 2, causing the working fluid permeated in the copper foam to boil efficiently and undergo a phase change. The gaseous working fluid generated by the vaporization phase change diffuses through the upper space of the miniature heat pipe shell 1 to the next working process. The high-temperature gas flow causes the condenser 3 to liquefy the gas, transforming it into a liquid. Due to the innovative technology of the condenser 3 of this invention, the liquid after phase change migrates rapidly under the action of van der Waals forces, improving the liquefaction phase change and accelerating heat dissipation efficiency. The liquid reservoir 6 is in close contact with the other end face of the vertical micro-groove 3-3 of the condenser 3. Due to capillary force, the liquid reservoir 6 draws in the working fluid. When the amount of working fluid in the condenser 3 is insufficient, the micro-groove of the condenser 3 absorbs the working fluid in the liquid reservoir 6 to replenish the working fluid under normal working conditions, ensuring the normal operation of the high-power micro heat pipe. The notch 4-1 of the capillary liquid transfer block 4 is in close contact with the liquid connection piece 2-3 in the boiling vaporizer 2, and the liquid receiving end face 4-2 is in close contact with the end face perpendicular to the longitudinal micro groove 3-3 of the condenser liquefaction 3. The liquefied liquid in the condenser liquefaction 3 is transferred to the liquid connection piece 2-3 in the boiling vaporizer 2 through the capillary liquid transfer block 4, and finally transferred to the boiling vaporizer 2, forming a loop circulation, continuously transferring the heat of the high temperature heat source to the finned heat sink 5 through the high-power micro heat pipe, realizing high-power heat dissipation.

The use of these terms is merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
