The utility model discloses a fin heat exchanger, which comprises a main plate of a heat exchanger and a flow path tube fixed on the main board of the heat exchanger for heat exchange. The upper and lower ends of the main plate of the heat exchanger are also provided with an additional heat transfer tube with a pipe bending position perpendicular to the bend direction of the flow pipe, and the additional heat exchanger tube and the adjacent heat exchanger. The flow pipe is connected. An additional heat transfer tube is set up and down at both ends of the main plate of the heat exchanger in order to improve the circulation of the refrigerant here, so that the heat exchanger at both ends of the heat exchanger is more fully heat exchange in the middle area, so that the cooling medium in the pipe can be filled with heat absorption and evaporation from the case of small air volume at both ends of the heat exchanger, thus reducing the cooling medium. The possibility of returning the liquid to the compressor reduces the liquid strike risk of the compressor; adds the vertical direction of the heat transfer tube, saves the space on the heat transfer main board, increases the pipeline density in the local area, so as to ensure a more sufficient heat transfer. The utility model also discloses an air source heat pump.

一种翅片换热器及空气源热泵
本技术涉及空调设备
,更具体地说,涉及一种翅片换热器,还涉及一种空气源热泵。
技术介绍
热泵为从低温热源吸收热量之后通过压缩机做功把这部分热量传递给高温热源的这样一种装置,从而实现了能量的转移。目前,大多数空气源热泵产品不仅能制热,而且还兼顾制冷。现有技术中,空气源热泵在采用侧出风的结构时,往往翅片换热器主板上的流路均匀分布,不同位置的流路分布情况相同。实际上风机在整个换热过程中每个位置风量并不一样,相对于中部风量来说,上部和下部的风量要小得很多,整个系统风量中部区域不同位置之间的风量偏差在±5%之间,在可接受的偏差范围之内。染而风机上下两端的换热器位置的风量相对于中部区域、只有中部区域风量的80%,这将很大程度上地影响整个换热效果。系统中由于中部区域区和两端区域风量的不同,这将导致在低温制热工况中翅片换热器上部和下部冷媒得不到充分地吸热并蒸发成气态冷媒,一方面影响了系统的换热效果,另一方面将会有一部分液态冷媒进入压缩机造成液击;而在制冷时可能会导致过冷度不够影响影响换热。综上所述,如何有效地解决目前的翅片式换热器在应用于空气源热 ...
