Description
Technical field:
The utility model relates to the compact microchannel heat exchanger of thermal energy exchange between a kind of working fluid and refrigeration working medium, be particularly related to Teat pump boiler, the condenser that uses in heat pump boiler and the geothermal heat pump, gas cooler or evaporimeter belong to heat transfer heat transfer technology field.
Background technology:
Teat pump boiler all be unable to do without heat exchanger in heat pump boiler and the geothermal heat pump, the performance of heat exchanging device, and size, quality and cost have all proposed very high requirement.To existing the said goods, under the condition that performance and quality are guaranteed, how to make heat exchanger do forr a short time, lighter, more low-cost, become the emphasis of research of technique.Under the certain condition of exchange capability of heat, make the heat exchanger densification, mean that the forced convection heat transfer coefficient of working fluid will improve greatly; The material that heat exchanger constitutes should the intensity height, also wants good heat conductivity, is fit to processing technology.
Researching and developing out at present the micro-channel heat exchanger that is used for heat pump, nearly all is to add the import and export of refrigeration worker system and add and import and export that the worker of freezing makes heat exchanging fluid realize with ready-made aluminum flat tube.As the micro-channel heat exchanger that is used for heat pump of setting forth in number of patent application 200510012007.6,200810115272.0 and 200510079932.0, all be idea or the material object that on the basis of aluminum flat tube, proposes.The structure of the micro-channel heat exchanger that proposes in the number of patent application 200510012007.6 is, many headers and be welded on two flat heat exchange pipe bundles between header, flat heat exchange pipe Shu Caiyong MCA, header adopts many barrel structures of at least two runners, it is characterized in that the header of many barrel structures and the integral planar structure that flat heat exchange pipe bundle solder side adopts extrusion molding.Above structure is the soldering combination between the fin that microchannel that refrigeration worker system is passed through and working fluid pass through, and consequent heat transfer resistance be can not ignore.Simultaneously flat heat exchange pipe is subject to processing the restriction of technology, and the combination to the hydraulic diameter that designs good heat-transfer can implement difficulty or cost is greatly improved.The evaporimeter of the use micro-channel tubes of invention in the micro-channel heat exchanger of invention and the number of patent application 200510079932.0 in the number of patent application 200810115272.0, be that with the difference of the micro-channel heat exchanger of statement in the number of patent application 200510012007.6 the flat heat exchange pipe bundle is to be parallel to ground also to be perpendicular to this overall structure of ground, the flat heat exchange pipe bundle is during perpendicular to ground, help dredging of condensed water, reduce the heat exchange thermal resistance of fin surface under wet cooling condition, help strengthening and conduct heat, improve the heat exchange property of freeze cycle process.But the welding thermal resistance problem between banded pipe in microchannel and the fin, any hydraulic diameter manufacturing cost problem of the microchannel in the banded pipe in microchannel still exists.
Above-mentioned number of patent application is that the refrigeration worker in the micro-channel heat exchanger of representative is made as nature refrigerant or hfc refrigerant, and working fluid is an air.For the microchannel diameter of CO2 in the natural refrigerant, the scope that provides in the number of patent application 200510012007.6 is 0.7 to 1.2mm, and the scope that provides in the number of patent application 200810115272.0 is 0.3 to 3mm.To be used for working fluid be liquid owing to also do not find at present, such as the micro-channel heat exchanger of water, is that the microchannel diameter of the hydraulic fluid side of water and the refrigeration worker micro-channel heat exchanger of making heat exchange need be studied and decides for working fluid therefore.
Summary of the invention:
The purpose of this utility model is at the deficiencies in the prior art, realization is used for liquid and the refrigeration worker makes the micro-channel heat exchanger of heat exchange, as Teat pump boiler, the condenser that uses in heat pump boiler and the geothermal heat pump, gas cooler or evaporimeter usefulness greatly improve the exchange capability of heat of unit volume heat exchanger, save heat exchanger and use material, thereby reduce Teat pump boiler, the volume and weight of heat pump boiler and geothermal heat pump.
The utility model is achieved in that compact microchannel heat exchanger, comprise housing, on described housing, be provided with the import and export of high temperature fluid import and export and cryogen respectively, it is characterized in that: described housing is provided with the microchannel that some plural passage stacked on top of one another form, odd number layer plural number passage is imported and exported with described high temperature fluid and is communicated on the described microchannel, and its even numbers layer plural number passage is imported and exported with described high temperature fluid and communicated.
Interlayer is all being arranged between the high temperature fluid passage, between the cry-fluid passage and between high temperature fluid passage and the cry-fluid passage.
The micro-channel heat exchanger that the utility model proposes and realize is combined into as a whole MCA by the atom diffusion then by the sheet metal lamination of having processed behind the plural passage.The number of plies of microchannel, the columns of every layer of microchannel and the hydraulic diameter of microchannel can be according to heat transfers, the result of heat exchange and mobile performance design, compressive resistance, the design result of rigidity decides.Concrete structure is presented below: processed refrigeration working medium side sheet metal behind the plural passage about, stack is without any the sheet metal of passage, workflow side sheet metal after having processed plural passage again on without any the sheet metal of passage, after the stack, just can design the micro-channel heat exchanger that the size that is met the heat exchange amount and working fluid pressure lose restrictive condition so successively.No matter be the microchannel size of refrigeration working medium side or the microchannel size on workflow side and, can realize conducting heat the design parameter of heat exchange and mobile performance design, compressive resistance, the designing requirement of rigidity without any the thickness of the sheet metal of passage.
The utility model compared with prior art has following advantage:
1. volume is little, under the condition of same exchange capability of heat, compares with double pipe heat exchanger just in use, and volume can reduce more than 100 times.
2. in light weight, under the condition of same exchange capability of heat, to compare with double pipe heat exchanger just in use, weight can be reduced to below 1/8th.
3. the heat transfer area in the unit volume has reached the index of compact heat exchanger definition greater than 700.
