Description

Technical Field

[0001] This utility model relates to the field of solar heating technology, specifically to a heat pump-assisted solar heating device. Background Technology

[0002] With the increasing global demand for clean energy, solar energy, as a renewable and clean energy source, is being used more and more widely in the heating field. Traditional solar heating devices mainly rely on solar collectors to collect solar energy and convert it into heat energy.

[0003] However, existing solar heating devices typically use solar energy to directly heat the heat exchange components (i.e., the water storage chamber), and then use heat exchange to send the heat (i.e., hot air) into the room to complete solar heating. However, the heat exchange components are often directly exposed to the sun, and sunlight often only shines on one side, which easily leads to the waste of solar energy. In addition, the heat exchange space and distance provided during the heat exchange process are often short, so the air circulating is often not fully heated, resulting in low heat exchange efficiency. The heat transfer and conversion process is not efficient enough, leading to serious energy waste. Utility Model Content

Simultaneously, air flows within the guide mechanism, exchanging heat with the heat exchange fins over a long distance, ensuring the air is fully heated and improving heat exchange efficiency. This allows for more efficient heat utilization. Furthermore, the return pipe and protective sleeve of the guide mechanism are positioned on the concentrating side of the concentrating mechanism. The concentrating mechanism reflects and concentrates sunlight that cannot be blocked by the return pipe, allowing both sides of the return pipe to receive sunlight. The protective sleeve, with its dark color, absorbs heat from the sunlight more effectively, further enhancing heat acquisition efficiency. The return pipe allows the internal medium (i.e., the flowing liquid) to be heated under sunlight for a longer period. After the medium enters the guide tube, the collected heat is better transferred to the air in contact with the heat exchange fins. The larger contact area of ​​the heat exchange fins with the air facilitates rapid heat dissipation, resulting in better heating and enhanced heat transfer and utilization.

[0044] In this invention, the working steps of the device are as follows:

[0045] 1. First, fix the protective cylinder 101 to the wall with expansion screws, or install it in a suitable position with the help of an external support structure and ensure stability. Fix the guide cylinder 301 in the middle of the protective cylinder 101 with the limiting plate 104 and the limiting groove 105.

[0048] 4. Finally, the hot air after heat exchange is discharged through the exhaust duct 102 and transported by the delivery pipe 402 to the indoor space that needs heating or other designated locations to achieve effective utilization of heat.
