| 摘要: |
| 本文提出多联式热泵驱动热管的新型供热循环方式。该方式的特征是采用空气源热泵直接驱动串联式热管散热器供热。为验证该供热方式可行性，本文基于额定功率为2.5 kW的压缩机和9台热管散热器搭建了实验台，在不同工况下进行测试。测试结果表明：新型供热装置启动速度较快，当室外温度为-10 ℃时，系统运行36 min时，热管散热器表面温度即可达到45 ℃。热管散热器温度均匀性好，除1#、9#散热器存在过冷、过热现象外，其余散热器之间温差约为1 ℃。同时系统传热温差小，并能在除霜工况下正常运行。 |

| Abstract: |
| A heating cycle mode of heat pump drive multi-connected heat pipe is proposed. The feature of this method is that the air source heat pump is used to drive tandem heat pipe radiator for heating directly. In order to verify the feasibility of this heating method, an experimental platform was built based on a 2.5 kW compressor and 9 heat pipe radiators, and the device was tested under different working conditions. The test results show that the new heating device has a faster starting speed, when the outdoor temperature is -10 °C and the system runs for 36 minutes, the surface temperature of the heat pipe radiator can reach 45 °C. Heat is evenly distributed at the end of the heat pipe radiator. Except for 1# and 9# radiators, which have over-cooling and over-heating, the temperature difference between the other radiators is approximately 1 °C. At the same time, the system has a small heat transfer temperature difference and can operate normally under defrost conditions. |
