Abstract
The invention relates to a heat pipe type fin heat exchanger which is mainly characterized in that the inner part of each heat exchange fin is a cavity, the inner part of each cavity is in a vacuum state, and a heat transfer medium is filled in each cavity. A heat pipe fin module is formed by combining a plurality of single heat pipe fins along different dimensional directions, heat pipe fin cavities can be mutually independent and are not communicated, and the heat transfer medium is filled in each single vacuum cavity; and the heat pipe fin cavities can also be mutually communicated to form a whole, and the heat transfer medium is filled in the whole vacuum cavity. The equivalent heat conduction coefficient of the heat pipe type fin heat exchanger of the invention is thousands of times of the heat conduction coefficient of a solid metal fin, and the heat pipe type fin heat exchanger has very small heat resistance and very high isothermal performance. Thus, the base surface temperature of a two-dimensional heat exchange surface and a three-dimensional heat exchange surface which are formed by the invention is infinitely close to the base surface temperature of a one-dimensional heat exchange surface, which can be considered as isothermal heat exchange, and the heat efficiency is close to 95%-99%.
Description
Technical field the present invention relates to the fin on a kind of heat-exchanger rig, particularly heat-exchanger rig.
Background technology is present, in heat exchange fields such as fluid thermal exchange, solar energy heating and power electronics heat radiations, in order effectively to utilize heat transfer space, enhanced heat exchange effect, heat-transfer surface generally can be by One-Dimensional Extended to two dimension and then extend to three-dimensional again, the concrete practice is to be provided with the entity mental-finned on heat-transfer surface, this fin comprises fin, fin and fin, and commonly used has: pipe face ring rib, pipe face side rib, the straight rib of pipe face, the pipe face rib of column, the plate face rib of column and the straight rib of plate face.Although above-mentioned fin can improve heat exchange efficiency, but also there is weak point in it, promptly cause owing to entity mental-finned self thermal resistance, there is thermograde in the heat conduction of entity mental-finned along its short transverse (the free-ended distance from the fin stiff end to fin), the entity fin height is high more, its heat-transfer surface basal plane temperature will be low more, heat exchange efficiency will be low more, therefore general entity mental-finned height is unsuitable too high, that is to say that the expansion of heat-transfer surface two-dimensional directional and three-dimensional is subjected to the restriction of entity mental-finned heat exchange efficiency, propagation size is limited.
Summary of the invention the object of the present invention is to provide a kind of unit space heat-transfer surface two dimension, three-dimensional extended scope big, heat exchange efficiency height, the heat pipe type fin heat exchanger of compact conformation.
The present invention is provided with the vacuum cavity that is filled with heat-transfer working medium in the heat exchange fin.Fin of the present invention is a heat pipe type fin, and promptly the structure of fin (comprising the rib of column, rib of slab) and operation principle are all identical with heat pipe, and this fin can be the monomer heat pipe fin that uses separately, also can be the heat pipe fin module that is used in combination.Wherein monomer heat pipe fin profile can have multiple, as plume rib and hot plate rib etc., its inside is cavity, is vacuum state in the cavity, the inside fills heat-transfer working medium, and the above-mentioned monomer heat pipe fin of making in advance is weldering, expanded joint or be bonded on the object that needs heat exchange directly.Heat pipe fin module can be by several monomer heat pipe fins along different dimensional to combining, this heat pipe fin module has two kinds of cavitys to be communicated with form, one monomer heat pipe fin is combined by welding, expanded joint or bonding mode, heat pipe fin cavity is separate not to be communicated with, and fills heat-transfer working medium in the monomer vacuum chamber; Its two monomers heat pipe fin is combined by welding manner, and heat pipe fin cavity is interconnected and forms integral body, fills heat-transfer working medium in the integral cavity.This heat pipe fin module mainly contains plume fin and the combination of plume fin, plume fin and the combination of hot plate fin, hot plate fin and three kinds of patterns of hot plate fin combination.Three kinds of integrated modes of this heat pipe fin module, the vacuum cavity of monomer whose heat pipe fin have whole UNICOM and two kinds of forms of independent existence.
The metal material of above-mentioned monomer heat pipe fin and heat pipe fin module can adopt existing chemistry and comparatively stable simple metal and the alloy of physical property, for example copper, aluminium alloy, carbon steel or stainless steel etc.; And heat-transfer working medium can adopt existing chemistry and the comparatively stable liquid of physical property, for example water, acetone, ethanol, naphthalene, liquefied ammonia or liquid potassium, sodium etc.
The course of work of the present invention is summarized as follows: monomer heat pipe fin hot junction and the heat exchange of thermal source object are also conducted heat to the heat-transfer working medium in the heat pipe fin cavity, becoming gas behind this heat-transfer working medium absorption heat spreads to heat pipe fin cold junction, heat-transfer working medium after heat pipe fin cold junction and the heat exchange of low-temperature receiver object in the cavity becomes liquid, under gravity or the effect of capillary surface tension force, get back to the hot junction, and so forth circulation; Heat pipe fin module is that the one dimension heat-transfer surface links to each other with the thermal source object, it is two-dimentional heat-transfer surface that this one dimension heat-transfer surface conducts heat to hot plate, this two dimension heat-transfer surface scatters the high density heat along two dimensional surface fast by the phase transformation of its internal heat transfer working medium, heat is the phase transformation continuation shunting diffusion of heat pipe fin internal heat transfer working medium by three-dimensional heat-transfer surface simultaneously, and heat conducts to the low-temperature receiver object the most at last.
The present invention compared with prior art has following advantage:
1, equivalent heat conductivity of the present invention is thousands of times of entity mental-finned thermal conductivity factor, and thermal resistance is minimum, has very high isothermal performance.Therefore two-dimentional heat-transfer surface and the three-dimensional heat-transfer surface basal plane temperature that is made of the present invention is infinitely close to one dimension heat-transfer surface basal plane temperature, can be considered the isothermal heat exchange, and its thermal efficiency approaches 95%～99%.
2, the present invention has changed traditional heat exchange form, is 1.3-1.7 times of traditional heat exchange form thermal efficiency.
3, the present invention can realize heat-transfer surface to two dimension, three-dimensional expands on a large scale.
4, the present invention can be applicable to various heat exchange fields such as fluid thermal exchange, solar energy heating and power electronics heat radiation; And be specially adapted to precise and tiny heat exchange, thermal-arrest and heat radiation field.
