Background
The microchannel heat exchanger has stronger heat exchange capability, and at present, two types of air-cooled microchannel heat exchangers are commonly used in the market, one is an aluminum parallel flow microchannel heat exchanger, and the other is a microchannel light tube heat exchanger (also called as a light tube type micro microchannel heat exchanger).
At present, the inner diameter of a copper pipe is larger than that of the copper pipe and is more than 7MM, and the heat exchange efficiency is low. The micro-channel light tube heat exchanger has insufficient fin area for exchanging with air, and the heat exchange efficiency is low.
As for the aluminum parallel flow micro-channel heat exchanger, the heat exchanger consists of the porous micro-channel aluminum flat tubes and the fins, because the heat exchange surface area of the porous micro-channel aluminum flat tubes contacted with air is small, the heat exchange efficiency is low, dense hemp fins are needed to increase the heat exchange surface area, but because the fins are too dense, water and frost are easy to form, and the heat exchange effect is influenced.
For the light pipe type micro-channel heat exchanger, the surface area is more than 3 times larger than that of the aluminum parallel flow for the same diameter of the micro-channel, but the heat exchange surface area is much smaller due to no fins, so that the heat exchange capacity is influenced. The inner diameter of the micro channel of the light pipe type micro channel heat exchanger is too small, so that the internal resistance of the system is very large, the energy conversion efficiency of the system is influenced, and the light pipe type micro channel heat exchanger is only suitable for a changing scene with small heat exchange amount and is not practical in a system with large heat exchange amount. In addition, because of the microchannel light tube, when wind blows over the heat exchanger, the microchannel tube is easy to deform, thereby affecting the heat exchange efficiency and the service life of the heat exchanger.
