添加制造是热声应用中热交换器制造的一种选择。在热声装置中，热交换器放置在振荡流动中。仔细考虑热交换器的几何形状，可以检查优化热传递和温度梯度的方法的应用。附加制造作为一种替代制造技术被提出，它可以克服目前传统制造加工的局限性。六个相同的横流换热器被制造和测试，其中三个是不锈钢的，三个是铝的。振荡流在圆形断面通道中来回运动，水流在垂直于圆形断面的通道中流动。研究了不同传动比和平均压力下的换热和温度梯度。
Additive manufacturing is an option for the fabrication of heat exchangers for thermoacoustic applications. In thermoacoustic devices, heat exchangers are placed in oscillatory flow. A careful consideration of heat exchanger geometries examines the application of methodologies to optimise heat transfer and the temperature gradient. Additive manufacturing is proposed as an alternative fabrication technique that can overcome the current limitations of conventional fabrication machining. Six identical crossflow heat exchangers were made and tested, three from stainless steel and three from aluminium. The oscillatory flow moves back and forth through circular cross-section channels, and water flows in channels perpendicular to them. Heat transfer and temperature gradients were investigated at different drive ratios and mean pressures.
