MCHE Aluminum Microchannel Tube Heat Exchanger

Micro channel heat exchanger (MCHE) is a highly compact heat exchanger, whole body aluminum structure, the diameter of a single control refrigerant circulating about 1MM. Compared with conventional finned tube heat exchanger, MCHE using micro-sized heat transfer technology, smaller, lighter, heat rate increased by 50%, 50% less refrigerant charge fluence, fan power consumption is reduced accordingly. With rising raw material prices, air-conditioning product standards and environmental requirements continue to increase, micro channel heat exchanger is gradually replace traditional heat exchangers, and has been widely used in various fields, such as home air conditioning, commercial air conditioners, precision computer room air conditioners, heat pumps water heaters, refrigeration, air conditioning containers, train air conditioning, automotive air-conditioning and other fields.

MCHEs have an ingeniously simple design-made entirely of all aluminium which is not only lightweight but also prevents galvanic corrosion. The refrigerant-carrying tubes are formed to optimise heat transfer, thus enabling the production of more compact, but equally effective...

Product advantages

Advantage:
1. saving . Energy conservation is an important indicator of today's air conditioner . Conventional heat exchangers difficult to manufacture high-grade energy efficiency standards such as grade Ⅰ products , micro- channel heat exchanger would be the best choice to solve the problem .

2.outstanding heat transfer properties. In terms of household air conditioners , when the flow channel size less than 3mm,
gas-liquid two-phase flow and phase change heat transfer law will be different from the conventional larger size , the smaller the channel , the size effect is more obvious. When the tube diameter as small as ? When 0.5 ~ 1mm, the convective heat transfer coefficient can be increased by 50 % to 100 %. This enhanced heat transfer technology for the air conditioning heat exchangers,heat transfer enhancement measures appropriate to change the heat exchanger structure , process and air side , is expected toeffectively enhance the air conditioning heat exchanger to increase their energy levels.

3. promotion potential. Microchannel heat exchanger technology as well as to promote the potential of air heater air conditioningmanufacturing, can greatly enhance the competitiveness and sustainable development of enterprise products 
Compared with conventional heat exchangers, microchannel heat exchanger heat transfer coefficient is not only smallsize , highheat transfer efficiency , to meet higher energy efficiency standards, and has excellent pressure resistance , can CO2 as the working fluid cooling, in line with environmental requirements, has caused widespread concern in academic and industrial circles.Currently, the micro-channel heat exchanger key technologies - producing micro-channel parallel flow tubes in the country hasmatured , making the micro- channel heat exchanger using a scale as possible.
