Hot wall type heat exchanger

The invention discloses a hot wall heat exchanger. The hot wall of the hot wall heat exchanger includes an inner support device and a heat exchange partition wall covering the inner support device. section and the upper and lower ends for the left and right circulation of the phase change fluid; the hot wall is rectangular, and several hot walls of the same size are juxtaposed into clusters, or the hot wall is ring-shaped, and several hot walls of different sizes are nested in clusters ; Each adjacent hot wall is provided with channel strips or fins to facilitate the passage of fluid; the fluid side of all channel strips or fins outside the hot wall is divided into multiple regions, which is realized by the phase change fluid in the hot wall Heat exchange of heat exchange fluids. The compactness of the hot wall heat exchanger proposed by the present invention is higher than that of the current heat pipe, and it can be adapted to more heat exchange fields. The variable fluid circulation speed is accelerated, and the heat exchange efficiency is improved.
