Abstract
The invention discloses a micro heat pipe. The micro heat pipe comprises a heat pipe casing and working medium inside the heat pipe casing. The heat pipe casing is composed of at least one micro fluid pipes; both ends of every micro fluid pipe are sealed, the inside of the micro fluid pipe is filled with the working medium, and the micro fluid pipe is made of metal with high heat conductivity and flexibility and can be bent at different angles as required. The micro heat pipe is composed of a plurality of the independent micro fluid pipes, so that damage of one of the micro fluid pipes cannot affect radiation of the others micro fluid pipes. The micro heat pipe is high in heat transfer performance and good in use expandability and can avoid installation difficulty and meet the requirements of electronic components in different sizes on heat radiation.
Description
Technical field
The present invention relates to technical field of heat exchange, specifically, relate to a kind of micro heat pipe.
Background technology
Heat pipe is a kind of heat transfer element with high heat-transfer performance, and it carrys out transferring heat by the latent heat of phase change of working media in airtight vacuum shell, and inside heat pipe medium is subject to thermal evaporation, after rising to top, in radiating segment condensation heat release in bringing-up section.The heat transfer property of heat pipe is similar to the electric conductivity of superconductor, and therefore, it is large that it has heat-transfer capability, the feature that heat transfer efficiency is high.The heat transfer property superior because of it and technical characteristic and be widely used in energy-saving field.。At present, heat pipe is usually used in the fields such as equipment cooling, waste heat recovery and VMC.
Existing heat pipe structure is fixed, heat radiation is all air-heat pipe heat radiation, radiating efficiency is not high, how to found a kind of light, cost is low, be easy to install, save space, and efficiency of thermal transfer is high, directly with the heat pipe needing radiating element transmission of heat by contact, the real important research target belonging to current this area.
Summary of the invention
One provided by the invention can contact with needs radiating element maximum area, takies minimum space, and the micro heat pipe that heat transfer efficiency is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of micro heat pipe, comprises thermotube shell and the working medium being positioned at thermotube shell inside; Described thermotube shell is at least made up of a minisize fluid pipe; The two ends sealing of each described minisize fluid pipe, inside is filled with described working medium.
Each described minisize fluid pipe is a single hole fluid hose above, and all minisize fluid pipes are put in a row side by side or arranged more, then fixes formation entirety.
The surrounding of the above minisize fluid pipe is provided with radiating fin.
The above minisize fluid pipe is a concurrent flow porous micro channel flat tube, and Dou Shi two ends, each hole sealing of concurrent flow micro-channel flat, its inside is all filled with working medium.
The above minisize fluid pipe is the good metal material of conductivity of heat and pliability.
The working medium of micro heat pipe of the present invention is selected can be can be any one in water, inorganic matter, R22, R134a or R410a according to working environment.
The advantage of micro heat pipe of the present invention is:
(1) micro heat pipe of the present invention farthest can reduce heat transfer resistance, improves efficiency of thermal transfer, reduces heat loss;
(2) micro heat pipe of the present invention selects to have good flexibility metal, can curve different angles plane as required;
(3) micro heat pipe of the present invention is made up of multiple independent minisize fluid pipe, one of them has gone bad the heat radiation not affecting other minisize fluid pipe, its heat conveyance performance and use extended capability well, can be avoided installing difficulty, meet the needs of arbitrary size cooling electronic component.

Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the present invention is described in more detail.
First of micro heat pipe of the present invention implement structural representation as shown in Figure 1, comprise thermotube shell and the working medium being positioned at thermotube shell inside; Thermotube shell is made up of multiple single hole minisize fluid pipe; The two ends sealing of each minisize fluid pipe, inside is filled with working medium, and in the present embodiment, all minisize fluid pipes are closely in a row by putting side by side, then fix formation entirety.
Second of micro heat pipe of the present invention implement structural representation as shown in Figure 2, comprise thermotube shell, be positioned at working medium and the radiating fin of thermotube shell inside; The two ends sealing of each minisize fluid pipe, inside is filled with working medium, and in the present embodiment, all minisize fluid pipes have certain intervals and put into two rows side by side, form a whole.
The 3rd of micro heat pipe of the present invention implement structural representation as shown in Figure 3, comprise thermotube shell and the working medium being positioned at thermotube shell inside, thermotube shell is a concurrent flow porous micro channel flat tube, and Dou Shi two ends, each hole sealing of concurrent flow micro-channel flat, its inside is all filled with working medium.
The working medium of all embodiments is selected can be any one in water, inorganic matter, R22, R134a or R410a according to working environment above.Because micro heat pipe selects to have good flexibility metal, difformity can be curved as required, during work, evaporator section working medium is heated vaporization, and expansion Working medium gas reaches condensation segment rapidly, and condensed worker quality liquid flows back to evaporator section along micro-pore wall and completes diabatic process.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
