摘　　要：本文针对普通住宅房间设计了一台新型平板式热管换热器,该换热器结构紧凑、体积小巧。为研究该换热器的使用条件,本文开展了不同工质(R113、R141b以及这两种工质的混合物)对该热管换热器换热效率影响的实验研究。整个实验在夏季工况下进行,热管真空度为1×10^(-3)Pa,充液量(灌入热管换热器内的工质体积与热管换热器体积之比)为1/3。实验结果表明:该热管换热器热回收效率较高。在整个风量范围内,R141b作为工质的热管换热器换热效果最好,最高效率达到了58.2%。A plate heat pipe heat exchanger for room ventilation was designed. The advantages of the heat pipe heat exchanger are small and high compactness. In this paper, the effect of the working fluid （Rl13, R141b and their mixture） was investigated experimentally for the performance of the heat pipe heat exchanger. The overall experiments were carried out under the simulated summer condition, the vacuum of the heat pipe heat exchanger was set at 1 x 10-3 Pa, and the filling ratio （the ratio of the working fluid volume in the heat pipe heat exchanger to the volume of the heat pipe heat exchanger） was 1/3. The experimental results show that the heat pipe heat exchanger could gain a high efficiency of heat recovery. The effectiveness of heat pipe heat exchanger with R141b as working fluid is superior to other working fluid over the whole air volume range, and the maximum effectiveness could be reached 58.2%.
