Description
Technical field
The utility model relates to a kind of miniature micro channel heat exchanger technology, particularly the embedded heat exchanger of a kind of miniature microchannel metal circular tube.
Background technology
Home-use or commercial at present, industrial direct-fired HTHP or corrosion resistance heat exchanger great majority adopt be shell and tube, board-like, stacked, in environment more than 200 DEG C, board-like, stacked heat exchanger bears limited pressure, its stressed point is all in commissure, but weld seam is long again, pressure-bearing is subject to certain restrictions, and the weld seam of shell and tube is less, caliber, wall thickness adjustable, withstand voltage properties is better, in direct-fired or high temperature pressure corrosion environment, adopt the more of shell and tube, as fuel oil, combustion boiler furnace, baking oven etc., but the heat exchanger caliber adopted at present is larger, general caliber is all more than 1 millimeter, large has tens of hundreds of millimeter, therefore to be withstand voltagely subject to certain restrictions, thicken wall thickness volume weight added cost, the thick heat exchange efficiency of caliber is lower, volume is larger.
Summary of the invention
The purpose of this utility model is the deficiency in order to solve above-mentioned technology, and can bear pressure higher in high temperature, high pressure, corrosive atmosphere, heat exchange efficiency is higher, and volume is less, the embedded heat exchanger of security better miniature microchannel metal circular tube.
In order to achieve the above object, the embedded heat exchanger of the miniature microchannel of the one designed by the utility model metal circular tube, comprises miniature microchannel metal circular tube heat exchanger, is provided with heat-conducting layer in metal circular tube heat exchanger side, miniature microchannel.In miniature microchannel, metal circular tube heat exchanger opposite side is provided with reservoir.Thermal insulation layer is provided with in the outer layer side of reservoir.Heat-insulation layer is provided with in the outside of thermal insulation layer.Miniature microchannel metal circular tube heat exchanger is embedded between heat-conducting layer and reservoir.Described thermal insulation layer is coat Huo Tu paste layer.Heat-conducting layer is directly fixed with miniature microchannel metal circular tube heat exchanger.Etching groove on heat-conducting layer, miniature microchannel metal circular tube heat exchanger riveting or welding are closely fixed on groove.
Described miniature microchannel metal circular tube heat exchanger comprises collector tube, dry pipe, heat exchanger tube, and heat exchanger tube is placed between collector tube and dry pipe, and through the connecing of weldering forms mutually, and described heat exchanger tube internal diameter is 0.1mm ~ 0.4mm.Also support is provided with between heat exchanger tube.The shape of heat-conducting layer can be dull and stereotyped, also can be flute profile, drum-shaped, polygon and various geometry, and described heat-conducting layer can the height of environmentally temperature, can adopt metal or nonmetallic heat conductive material
Described metal guide thermosphere or nonmetallic heat conductive layer, can embed microchannel pipe in groove by etching groove, combines closely through riveting or welding and heat-conducting layer.Described heat-conducting layer and miniature microchannel metal circular tube heat exchanger also can not open channels, the form such as die casting, casting is adopted reservoir and heat-conducting layer to be combined closely, make miniature microchannel metal circular tube heat exchanger be embedded in centre, or be fixed on heat-conducting layer by other forms, make thermal resistance less.
At this, described reservoir can be the metal or nonmetallic materials that heat capacity ratio is higher, by forms such as die casting, casting, stickup, sintering, reservoir and heat exchanger and heat-conducting layer are combined closely integral, but thermal resistance is minimum, heat capacity ratio is maximum, and its thickness can decide according to the size of the size of quantity of heat storage and thermal resistance; Also the size can bearing pressure according to microchannel metal circular tube heat exchanger decides, and pressure is little, temperature is low, quantity of heat storage is few, can be thinner.If bearing capacity is large, temperature is high, and quantity of heat storage is large, then should be thicker, and reservoir not only plays heat accumulation effect, and also play the effect of protection microchannel pipe heat exchanger, being reservoir, is also protective layer.
Described thermal insulation layer can be metal or nonmetallic materials, also can be the paint coatings of composite material, it can be rigid material, also can be nonrigid material, can to chemically or physical means heat-barrier material and reservoir are bonded together, also can bundle, make the least possible loss of heat, reservoir is isolated from the outside out.
Described heat-insulation layer can be metal or nonmetallic materials, also can be composite material, can be rigid material, also can be flexible material, to play the effect protecting and prevent thermal loss, also plays energy-conservation effect.
The embedded heat exchanger of miniature microchannel metal circular tube that the utility model provides, because it adopts efficient heat-conducting layer and efficient miniature microchannel metal circular tube to make heat exchanger tube, because its internal diameter is between 0.1 ~ 0.4mm, there is the pole phase effect of microscopic heat conduction, entrance effect and capillary, draw ratio and internal-and external diameter sectional area volume ratio higher, the features such as heat transfer coefficient is high, heat transfer temperature difference is low, flow resistance is low.Experiment proves, on 100*10*1mm volume, built-in type microchannel pipe, uses water as medium, the heat of about the 700w that can swap out during heat-conducting layer temperature about 100 DEG C.Along with the rising of temperature, when reservoir temperature is raised to about 220 DEG C, the heat of about the 1600w that can swap out can be hot water, can also be steam, and its heat exchange amount increases along with the rising of temperature.When equilibrium temperature is more than more than 200 DEG C, especially obviously.As long as under the hot environment that heat-conducting layer and reservoir can bear, microchannel pipe heat exchanger just can bear, because heat exchanger tube and liquid in-out steam pipe are subject to the protection of reservoir and heat-conducting layer, the ability of bearing pressure is stronger.
The embedded heat exchanger of miniature microchannel metal circular tube that the utility model provides, because its volume is less, decrease explosion energy, outside also has heat-conducting layer and reservoir to protect, and under high temperature, hyperbaric environment, security is better.
The embedded heat exchanger of miniature microchannel metal circular tube that the utility model provides, because its heat exchange efficiency is high, under the prerequisite of identical heat exchange amount, volume can do more miniaturized, and weight is lighter, can reduce erection space, saves space.
The embedded heat exchanger of miniature microchannel metal circular tube that the utility model provides, can single, also can several serial or parallel connection, can also modular mode use, and all fields of---gas of liquid heat exchange or HTHP---the liquid heat exchange that can be widely used in high temperature, high pressure, corrosion resistant liquid, can be used for the heat exchange needs of national defence, nuclear energy, Aero-Space, chemical industry, boiler, baking oven, special air-conditioning units and all hot environments.
