一种用于斯特林热电转换装置的双盘管冷却器
技术领域
本发明属于热电转换发动机领域,具体涉及一种用于斯特林热电转换装置的双盘管冷却器。
背景技术
在斯特林热电转换装置中,冷却器是发动机的一个关键部件,用于冷却工作介质使回热器两端形成足够高的温度差;常规翅片-盘管冷却器一般为圆环形状,有的结构是外层为翅片,内层为冷却盘管,有的结构是内层为翅片,外层为冷却盘管,这种单边翅片-盘管结构,始终有一个侧面会直接与发动机热端高温壁面接触,工作介质在进入回热器之前就被高温壁面加热,减小了回热器两端的温度差,影响了发动机的工作效率。
发明内容
本发明的目的是提供一种用于斯特林热电转换装置的双盘管冷却器。
本发明的技术方案如下:
本发明的用于斯特林热电转换装置的双盘管冷却器,其特点是,所述的双盘管冷却器为圆环柱状结构,包含外管壁、外螺旋盘管、蜂窝状流道、内螺旋盘管和内管壁。所述的双盘管冷却器中的内螺旋盘管、外螺旋盘管内部中空,作为冷却介质的流道。蜂窝状流道由数个框架条构成空间框架结构,双盘管冷却器的上端面与下端面为多孔状。所述的双盘管冷却器的外层为外管壁,外管壁内表面与外螺旋盘管固定连接。内螺旋盘管位于外螺旋盘管内,内螺旋盘管与外螺旋盘管同轴设置。所述的内螺旋盘管与内管壁外表面固定连接。在外管壁、外螺旋盘管、内螺旋盘管和内管壁所构成的环状内部空间中填满蜂窝状流道,蜂窝状流道分别与外管壁、外螺旋盘管、内螺旋盘管和内管壁固定连接。双盘管冷却器的下端面设置有冷却介质流道的入口和出口,入口与出口之间呈一角度。外螺旋盘管的下端口与冷却介质流道的入口相连通,外螺旋盘管上端与内螺旋盘管上端通过U形弯管相连通,内螺旋盘管的下端与冷却介质流道出口相连通。
所述的入口5与出口4之间的角度范围为30度~300度。
本发明中,工作介质为高温的热流体,热流体从双盘管冷却器的上端面和下端面穿过流动,冷却介质从入口处流入外层螺旋盘管和内层螺旋盘管,螺旋盘管壁与周围热流体进行热交换,最后从内层螺旋盘管的出口处流出,进入冷却循环系统;热流体从双盘管的中间的空间穿过,热流体左右两边均为螺旋盘管壁冷却的蜂窝状空间,增大了热交换面积,本发明装置的重量轻、冷却效率高。
