Heat transfer performance of the Trombe wall implanted with heat pipes during daytime in winter
In order to improve the utilization rate of solar energy in winter, a new type of passive solar wall was proposed. Based on walls implanted with heat pipes and the Trombe wall, the Trombe wall implanted with heat pipes (TIHP) was presented. In this article, the ventilation, heat transfer, and outer surface temperature with the intensity of solar radiation were studied, and the heat transfer characteristics of the TIHP were compared with the wall implanted with heat pipes (WIHP). The results show that the TIHP transfers more heat absorbed by the outside surface of the wall into the indoors through the convective heat transfer of air and thermal conduction of heat pipes wall, thereby enhancing the utilization of low-quality solar energy. Under simulated conditions, the average temperature of the outside surface was 50.8 °C; meanwhile, the heat transfer resistance of the wall is effectively reduced. The average daily working hours increased to 6.2 h, and the heat transfer capacity is significantly improved.
