Abstract

A heat pipe type of heat transfer and elimination device used in semiconductor refrigeration is disclosed, which features that the mixed working medium is sequentially circulated in I-shaped heat pipe composed of collecting cavity, boiling chamber, evaporating cavity, condensing cavity, reflux hopper and reflux pipe. The natural convection of ordinary-temp air or water is used to refrigerate by heat exchange. Its advantages are no mechanically moving part, high reliability, saving energy, no polution and noise, and long service life.

Description

I-shaped circulating heat pipe

The invention belongs to heat pipe biography, heat abstractor that a kind of working medium that is applied in the conductor refrigeration circulates in worker's shape framework.

It is cylindrical that present heat pipe is a word, form by shell, tube core, evaporation cavity, working medium, mainly be applicable to high temperature section, and in 30 ℃ of-50 ℃ of temperature sections, do not have suitable working medium and a structure, therefore being applied in still needs the blower fan heat radiation on the conductor refrigeration, can not accomplish movement-less part and noiselessness fully.

The objective of the invention is to improve above-mentioned deficiency, mixed working fluid boiling in I-shaped framework, evaporation, heat transfer, heat radiation, condensation, constitute circulation, utilize the heat transfer free convection of air or water to carry out refrigeration, thereby thoroughly accomplish movement-less part, long-lived, reliable, energy-conservation, pollution-free, noiselessness.

Feature of the present invention is the worker's shape framework circulating heat pipe that is made of collecting chamber, boiling-house, evaporation cavity, condensation chamber, backflow funnel and return duct, it at the bottom of the I-shaped framework flat lumen, causing with acetone is the mixed working fluid structure that circulates of one-dimensional order ground very easily of base, cause simultaneously bigger heat-delivery surface again, make it in air or water, to get final product heat exchange refrigeration, on attached to casing, just form the casing heat radiating type: in being installed in intermediate water tank, just form casing water of radiation cold mould by free convection.

Accompanying drawing 1 is depicted as longitudinal section of the present invention.

Accompanying drawing 2 is depicted as A of the present invention to side view.

Accompanying drawing 3 is depicted as casing heat radiating type of the present invention.

Accompanying drawing 4 is depicted as casing water of radiation cold mould of the present invention.

Specify below in conjunction with accompanying drawing:

As Fig. 1,2. the end of I-shaped framework (down horizontal) is flat lumen, it is the collecting chamber (2) of mixed working fluid (1), form certain angle of inclination a with horizontal plane, collect in order to working medium, the hot side of position, intermediate portion contact semiconductor cooling chip (3), it is the position of directly accepting thermal source, be referred to as boiling-house (4), the top of boiling-house is to lean in I-shaped to be evaporation cavity (5), horizontal I-shaped is condensation chamber (6), several be the backflow funnel (7) being convenient to collect after the mixed working fluid condensation and the return ducts (8) of below thereof are being arranged below the condensation chamber, and return duct leads in the collecting chamber (2), constitutes I-shaped circulating heat pipe thus.

As Fig. 3, I-shaped circulating heat pipe is tight or integrated attached on the refrigeration casing, utilizes casing side big surperficial (9) to amass and carries out heat exchange, and air vent (10) is arranged on it, is beneficial to Natural Heat Convection.

As Fig. 4, I-shaped circulating heat pipe is installed in the intermediate water tank (11), fill water (12) in it, water tank is thin and high, be convenient to the water convection current, surface temperature height in the formation, the low thermograde of following surface temperature, water tank is also as casing one side, the water tank outer surface has than large tracts of land increases further increased area of radiated rib (13) simultaneously again, strengthen heat radiation, water inlet (14) arranged under the water tank, on delivery port (15) is arranged, water has absorbed behind the heat that I-shaped circulating heat pipe gives out self temperature and has risen, but the water after the pre-temperature of this kind is linked into saves energy in the hot-water cylinder in the cold and hot water drinking machine, and had not only utilized the refrigeration of semiconductor chip but also the heating that utilizes to a certain extent, play the effect of " dual-use ".

When taking in acetone as base, with methyl alcohol, ethanol, ether, potassium hydroxide is auxiliary material, and pour in the I-shaped circulating heat pipe with certain prescription, after vacuumizing sealing, just can start working, at first accept heat by the collecting chamber middle part, mixed working fluid seethes with excitement at boiling-house, expand into evaporation cavity rapidly, absorb in large quantities and the transmission heat, when the working medium of evaporating attitude rises in the condensation chamber of transverse presentation, because the structure that condensation chamber has the utmost point to be convenient to dispel the heat, big heat exchange area is promptly arranged, or by the cross-ventilation heat exchange, or be embedded in the water, absorb its heat by water, so, the rapid release heat of working medium just condensation is therein got off, vapor state becomes vapour drips, and is dripped by little vapour to become big working medium through the backflow funnel and drip again, and just gets back in the collecting chamber along return line flow, for the boiling-house recirculated work, finish the absorption heat thus, transmit heat, the process of distribute heat, because collecting chamber is the flat lumen and the certain angle that tilts, the working medium of boiling is laterally blocked by liquid refrigerant, can only supply its explosive evaporation continuously, and the gas of explosive evaporation can not reversely be diffused in the collecting chamber, cause the one-dimensional order circulation, therefore can efficient operation, in addition, in this process, there is not mechanical moving element, there is not noise, efficient energy-saving, pollution-free, can constitute new generation of semiconductor refrigerator with breakthrough.
