Abstract
In order to solve the problems of thermal fatigue, high temperature
gasification and low temperature solidification of the heat receiver, a
numerical calculation model for the heat transfer function of the tower type
solar thermal power gener?ation high temperature receiver is proposed. A
perfect analysis method is used for the simulation, and a thermal simulation
program for predicting the heat gain of the solar thermal energy tower is
compiled. In this paper, considering the various field connection
characteristics, numerical value and distribution of convective heat
transfer coefficient of the heat absorption medium, the temperature of the
outer wall of the heat pipe absorption, and the thermal image conversion
work in a non-uniform heat flow boundary area of a model of heat receiver
was studied. The experiments show that when the flow rate of molten salt in
the tube increases from 1 m/s to 2 m/s, the heat collection efficiency of
the heat collection increases rapid?ly, while the flow time is more 3 m/s,
the heat collection efficiency increases more gradually. The efficiency of
heat absorption of the heat receiver is in the middle of the heat receiver,
which can achieve 88 of the thermal image conversion. In the same large
enough value, the heat collected at the inlet and outlet of the heat sink is
about 82. It is clear that the numerical simulation provides a reliable
basis for the design engineering, and provide guidance for the design of a
full control model of tower solar photovoltaic power generation.
