Abstract
The invention designs a heat exchanger provided with micro micro-channel metal circular pipes for an air cooled air conditioner. The heat exchanger comprises an inlet pipe, an outlet pipe and a heat exchange mechanism, wherein the inlet pipe is connected with the outlet pipe through the heat exchange mechanism. The heat exchanger is characterized in that the heat exchange mechanism is constructed by crossly weaving the micro micro-channel metal circular pipes and metal wires; the micro micro-channel metal circular pipes are radial lines with the two ends being connected with the inlet pipe and the outlet pipe and the inner diameters being 0.1-0.4 millimeter; the metal wires are weft lines, and are connected with the micro micro-channel metal circular pipes by welding. The entire heat exchanger is constructed by taking the micro micro-channel metal circular pipes as a major heat exchange mechanism and taking the metal wires as support frameworks.
Description
Technical field
The air-cooled type heat exchanger of miniature microchannel metal circular tube of the present invention, be related to all using air-cooled industrial sky
Tune, civil air conditioner and auto air-con, or the field such as microelectronics and air-source water heater.
Background technology
At present domestic air conditioning, air conditioning for automobiles and other adopt in air-cooled heat exchanger, the aluminum using extrusion molding closes
Golden flat tube, its endoporus minimum dimension is all higher than 0.6mm, therefore referred to as large scale micro-channel heat exchanger although than traditional pipe type,
Corrugated tube type, parallel flow type, plate-fin, the heat exchanger efficiency such as stacked improve many, but it also fails to reach microscopic heat conduction.Micro-
Type micro-channel heat exchanger at present more uses board-like micro-channel heat exchanger, is used for liquid-liquid heat exchange.And it is used for solution-air heat
Exchange i.e. be used for air-cooled heat exchanger also there is no this class formation.
Content of the invention
The invention aims to solving the deficiency of above-mentioned technology and providing a kind of high heat transfer coefficient, high surface-body
Long-pending ratio, the heat exchanger of the miniature microchannel metal circular tube for Wind-cooling type air-conditioner of the low heat transfer temperature difference, low flow resistance.
In order to achieve the above object, the miniature microchannel metal circular tube for Wind-cooling type air-conditioner designed by the present invention
Heat exchanger, it includes inlet tube, outlet and heat exchange mechanisms, is connected by heat exchange mechanisms between inlet tube and outlet, and it is special
Levy and be that heat exchange mechanisms are worked out with wire cross using miniature microchannel metal circular tube, described miniature microchannel metal
Pipe is radial line, and two ends are connected with outlet with inlet tube, and internal diameter is between 0.1～0.4mm, and tinsel is parallel, and with
Miniature microchannel metal circular tube is welded to connect.The feature of this structure is to employ miniature microchannel metal circular tube as main
Heat exchange mechanisms, tinsel as supporting framework, forms whole heat exchanger.
In order to adapt to the needs of various different use environments, described inlet tube and outlet adopt the gold of different-diameter
Belong to pipe, flat tube or type pipe, fluting or perforate on its tube wall, miniature microchannel metal circular tube passes through fluting or perforate and import
Pipe, outlet are welded and fixed.
In order to improve the heat exchange efficiency of heat exchanger, in described inlet tube and outlet, division board is provided with by fluting.
Conduction hole also can be provided with, to guide the airflow direction in heat exchange mechanisms on division board.
In order to increase the service life of heat exchanger, described heat exchange mechanisms surface, and the surface of inlet tube and outlet
It is equipped with corrosion proof and leakproof layer.
In order to improve heat exchange efficiency further, described heat exchange mechanisms Multi-layer Parallel is between inlet tube and outlet.
The heat exchanger of the miniature microchannel metal circular tube for Wind-cooling type air-conditioner designed by the present invention, by using micro-
Type microchannel metal circular tube, improves efficiency of heat exchanger, it is demonstrated experimentally that when microchannel diameter is less than 0.4mm, macroscopic theory is public
Formula is no longer applicable.Now the frictional resistance of miniature microchannel metal circular tube is greatly reduced, about the 32%- of macroscopic theory value
42%；Heat flow density is up to 100-150, and typically traditional heat exchange form can only achieve 10-20, and the thermal efficiency greatly improves, up to 0.95
More than；Nu Saier coefficient (power of reflection convection heat transfer' heat-transfer by convection) reaches as high as 9.20, and traditional macro passage is up to 8.23.With
When, by the way of braiding, add parallel wiry, increased windage, slow down wind speed, improve heat transfer effect；Also there is body
Long-pending little, lightweight, heat exchange efficiency is high, saves material, and reduces packaging and the feature of cost of transportation.
