The invention provides a heat exchanger of a helicopter cooling system. The heat exchanger comprises a shell; a core body which is arranged in the shell; cold edge inlet and outlet assemblies which are arranged at the two ends of the shell and used for enabling cold edge fluid to flow into or out of the core body and carrying away heat of hot edge fluid; and a hot edge inlet and outlet assembly which is arranged at the top or the bottom of the shell and used for enabling the hot edge fluid to flow into a channel between the shell and the core body or flow out of the channel; according to the heat exchanger, the overall dimension is small, the weight is light, the core body of the heat exchanger is designed to be of a cylindrical hollow structure and placed in the shell, a countercurrent flow heat exchange mode is formed when cold and hot fluid works, and the heat exchange efficiency is improved.

    本发明提供了一种直升机冷却系统的热交换器,包括:壳体;芯体,设置在所述壳体内;冷边进出口组件,设置在所述壳体的两端,用于冷边流体流入或流出所述芯体,并携带走热边流体的热量;热边进出口组件,设置在所述壳体的顶部或底部,用于所述热边流体流入所述壳体与所述芯体之间的通道,或从所述通道流出;本发明提出的一种热交换器,外廓尺寸小、重量轻,将热交换器芯体设计为圆柱空心结构,并放置于壳体内部,冷热流体工作时形成逆流换热方式,提升了换热效率。
