The embodiment of the invention relates to the technical field of charging piles, in particular to a heat exchange mechanism which comprises a shell, a heat dissipation piece and a cover plate. The shell is provided with a containing cavity, a first flow guide groove and a second flow guide groove which are communicated with each other are formed in the containing cavity, and the first flow guide groove and the second flow guide groove are communicated with the external environment; and a horizontal flow channel is also arranged in the first flow guide groove and/or the second flow guide groove. The heat dissipation piece is installed in the first flow guide groove and/or the second flow guide groove. The cover plate is connected with the containing cavity, the cover plate is matched with the first flow guide groove to form a first heat dissipation area isolated from the containing cavity in a sealed mode, and the cover plate is matched with the second flow guide groove to form a second heat dissipation area isolated from the containing cavity in a sealed mode. By means of the design, the module needing heat dissipation is installed in the first heat dissipation area and/or the second heat dissipation area and is isolated from the containing cavity in a sealed mode, so that dust and other impurities in the external environment are prevented from entering the containing cavity, and the heat dissipation efficiency is improved.
本申请实施例涉及充电桩技术领域,特别是涉及了一种换热机构,换热机构包括外壳、散热件和盖板。外壳设有收容腔,收容腔内设置有相连通的第一导流槽和第二导流槽,第一导流槽和第二导流槽分别与外界环境连通;第一导流槽和/或第二导流槽内还设置有水平流道。散热件安装于第一导流槽和/或第二导流槽。盖板与收容腔连接,盖板与第一导流槽配合形成与收容腔密封隔离的第一散热区域,盖板与第二导流槽配合形成与收容腔密封隔离的第二散热区域。通过上述设计,将需要进行散热的模块安装于第一散热区域和/或第二散热区域,并且均与收容腔密封隔离,从而防止外界环境的灰尘等杂质进入收容腔,从而提高散热效率。
