Abstract
The utility model relates to the refrigeration filed, in particular to a heat exchanger with micro-channels. The heat exchanger with the micro-channels comprises a support. A collecting pipe one and a collecting pipe two are respectively arranged on the support and are placed parallel to each other. 20-120 flat tubes are connected between the collecting pipe one and the collecting pipe two and are communicated with inner cavities of the collecting pipe one and the collecting pipe two. S-shaped fins are arranged between the flat tubes. Side plates are welded with the two ends of the collecting pipe one and the two ends of the collecting pipe two. The collecting pipe one and the collecting pipe two are respectively sealed with end covers. An outlet pipe, an inlet pipe and a coupling are arranged on the collecting pipe one. A heat shrink tube is connected with the coupling and abrasion of the collecting pipes, the couplings and the like can be avoided. The flat tubes and the collecting pipes are made of aluminum alloy materials. The fins are formed by aluminum foil sheets in a folded mode. The heat exchanger with the micro-channels is high in heat exchanging efficiency, light in weight, high in reliability and low in cost.

Technical field
The utility model relates to refrigerating field, and is especially relevant with a kind of micro-channel heat exchanger.
Background technology
Micro-channel heat exchanger claims again parallel-flow heat exchanger, is a kind of high-efficiency compact formula heat exchanger, the substitute products of fin-tube type heat exchanger, in recent years, along with the rising all the way of copper valency, the substitution problem of air-conditioning system copper material has caused the common concern of industry field, and actively seeks the substitute technology of copper material.
The utility model content
The purpose of this utility model will solve above-mentioned existing various weak points exactly, and a kind of compact appearance is provided, the micro-channel heat exchanger that heat exchange efficiency is high, lightweight, reliability is high and cost is low, for this reason, the utility model by the following technical solutions:
A kind of micro-channel heat exchanger comprises support, it is characterized in that: described header one and header two are rack-mount respectively, and header one is parallel placement with header two; Be connected between header one and the header two and 20-120 the flat tube that communicates with two header inner chambers, be provided with the fin of S shape between flat tube; Header one and header two two ends welding side plate, header one and header two are used respectively end cap seal; At header one outlet, inlet tube and pipe joint are installed, heat-shrink tube is connected on the pipe joint, can prevent that header, pipe joint etc. are corroded.
As the further of such scheme improved and replenish, the utility model also comprises following additional technical feature:
Described fin is folded to form by aluminium foil, has shutter on the fin, and both sides and flat tube weld together.
Described dividing plate inserts in header one, two the inner chamber, and header one is become a plurality of independently cavitys with the header two compartment.
Described flat tube is the pipeline of flat pattern, and there are a plurality of square grooves inside.
Described flat tube, header one and header two are aluminium-alloy pipe.
When the utility model uses, the utility model is installed in air-conditioning or the refrigerating equipment, liquid refrigerant absorbs after the heat of the object that is cooled in evaporimeter, be vaporized into the steam of low-temp low-pressure, enter heat exchanger sucked, be compressed into the steam of high pressure-temperature by compressor after, cold-producing medium flows in the flat tube of microchannel, to cooling medium (water or air) heat radiation, be condensed into highly pressurised liquid, be the cold-producing medium of low-pressure low-temperature through the choke valve throttling; Again enter evaporimeter heat absorption vaporization, reach the purpose of circularly cooling.
Use the utility model can reach following beneficial effect: because its compact conformation, volume are little, full aluminium design, lightweight, easily reclaim and cost low; Heat exchange efficiency is high, reliability is high; Easy to use.
