本章介绍了微（小）通道及其在太阳能系统中的应用。两种类型的通道，微（迷你）管和微（迷你）热管，已被提出，并在太阳能系统中使用的性能已经说明了在文献中的研究。对于太阳能热系统，微（迷你）通道的集成可以显着提高热性能，与传统通道相比提高了28%。对于PVT系统，微（迷你）通道的使用还通过降低PV板的温度来增强电输出。因此，这些通道的使用增加了PVT系统的总效率，其可以实现约70%的总效率。此外，在本文中，微通道的使用已经说明了一种新型的太阳能PVT回路热管的研究，采用微通道热管蒸发器和PCM三重换热器。该图示示出了环境参数（即太阳辐射、空气温度、风速）、结构参数（即玻璃罩、吸热管的数量、PC电池填充因子）和可变输入（即水入口温度、质量流率），这些参数可以影响新型PVT系统的总体效率。本章表明，微（小）通道在太阳能系统中的应用是有前途的，它们在太阳能技术中的集成可以显着提高其性能和市场份额。
This chapter presented micro (mini)-channels and their applications in solar systems. Two types of channels, micro (mini)-tubes and micro (mini)-heat pipes, have been presented, and the performance of their use in solar systems has been illustrated by studies in the literature. For solar thermal systems, the integration of micro (mini)-channels can increase significantly the thermal performance that achieves an increase of 28% compared to conventional channels. For PVT systems, the use of micro (mini)-channels enhances also the electrical output by decreasing the temperature of PV panels. Consequently, the use of these channels increases the overall efficiency of PVT systems that can achieve the overall efficiency of around 70%. Furthermore, in this paper, the use of micro-channel has been illustrated by the investigation of a novel solar PVT loop heat pipe employing a micro-channel heat pipe evaporator and a PCM triple heat exchanger. This illustration showed environmental parameters (i.e. solar radiation, air temperature, wind velocity), structural parameters (i.e. glazing covers, number of the absorbing heat pipes, PC cell packing factor) and the variable inputs (i.e. water inlet temperature, mass flow rate) that can influence the overall efficiency of the novel PVT system. This chapter showed that application of micro (mini)-channels in solar systems is promising, and their integration in solar technologies can enhance significantly their performance and their market share.
