Description
Technical field
Miniature microchannel of the present utility model metal circular tube Wind-cooling type heat exchanger, relate to all and adopt air-cooled industrial air-conditioning, civil air conditioner and auto air-con, or the fields such as microelectronics and air-source water heater.
Background technology
At present in domestic air conditioning, air conditioning for automobiles and the air-cooled heat exchanger of other employings, what adopt is the aluminum alloy flat tube of extrusion modling, its endoporus minimum dimension is all greater than 0.6mm, therefore be called the large scale micro-channel heat exchanger, although improve manyly than traditional pipe type, corrugated tube type, parallel flow type, plate-fin, the heat exchanger efficiency such as stacked, it also fails to reach the minute yardstick effect.It is board-like micro-channel heat exchanger that miniature micro-channel heat exchanger adopted at present, multiplex in liquid-liquid heat exchange.And be used for the solution-air heat exchange namely be used for air-cooled heat exchanger also there is no this class formation.
The utility model content
The purpose of this utility model is the heat exchanger that the miniature microchannel metal circular tube that is used for the Wind-cooling type air-conditioner of a kind of high heat transfer coefficient, high surface-volume ratio, the low heat transfer temperature difference, low flow resistance is provided for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the heat exchanger of the miniature microchannel metal circular tube that is used for the Wind-cooling type air-conditioner that the utility model is designed, it comprises inlet tube, outlet and heat exchange mechanisms, connect by heat exchange mechanisms between inlet tube and outlet, it is characterized in that heat exchange mechanisms adopts miniature microchannel metal circular tube and wire cross to work out, described miniature microchannel metal circular tube is radial line, two ends are connected with outlet with inlet tube, and internal diameter is between 0.1～0.4mm, wire is parallel, and with miniature microchannel metal circular tube, is welded to connect.The characteristics of this structure have been to use miniature microchannel metal circular tube as main heat exchange mechanisms, and wire, as supporting framework, forms whole heat exchanger.
In order to adapt to the needs of various environment for use, described inlet tube and outlet adopt metal circular tube, flat tube or the type pipe of different-diameter, fluting or perforate on its tube wall, miniature microchannel metal circular tube is welded and fixed by fluting or perforate and inlet tube, outlet.
, in order to improve the heat exchange efficiency of heat exchanger, be provided with division board by fluting in described inlet tube and outlet.Also can be provided with conduction hole on division board, with the airflow direction in the guiding heat exchange mechanisms.
In order to increase the service life of heat exchanger, described heat exchange mechanisms surface, and the surface of inlet tube and outlet is equipped with the corrosion proof and leakproof layer.
In order further to improve heat exchange efficiency, described heat exchange mechanisms Multi-layer Parallel is between inlet tube and outlet.
The heat exchanger of the miniature microchannel metal circular tube that is used for the Wind-cooling type air-conditioner that the utility model is designed, by using miniature microchannel metal circular tube, improve efficiency of heat exchanger, experimental results show that, during less than 0.4mm, the macroscopic theory formula is no longer applicable when microchannel diameter.This moment, the frictional resistance of miniature microchannel metal circular tube greatly reduced, and was about the 32%-42% of macroscopic theory value; Heat flow density is up to 100-150, and general traditional heat exchange form can only reach 10-20, and the thermal efficiency greatly improves, and can reach more than 0.95; Nu Saier coefficient (power of reflection convection heat transfer' heat-transfer by convection) reaches as high as 9.20, and the traditional macro passage is up to 8.23.Simultaneously, adopt the mode of braiding, add parallel wiry, increased windage, the wind speed that slows down, improve heat transfer effect; Also have volume little, lightweight, heat exchange efficiency is high, economical with materials, and the characteristics that reduce packing and cost of transportation.
