The Centre for Advanced Coating Technology (CACT) at the University of Toronto has used thermal spray technology to developing high efficiency heat exchangers and heat pipes. Heat exchanger efficiency can be improved by bonding porous wire meshes, perforated sheets, or metal foams to the surface of heat exchanger tubes, increasing the area for heat transfer. CACT has developed a bonding technique, using a wire-arc spray coating method, to bond metal meshes, foams and perforated sheets to tubes. We will use high-efficiency heat exchangers for a variety of applications, including waste heat recovery, gas heaters and industrial ovens.

多伦多大学的先进涂层技术中心（CACT）已经使用热喷涂技术开发了高效热交换器和热管。热交换器的效率可以通过将多孔金属丝网、穿孔板或金属泡沫粘合到热交换器管的表面来提高，从而增加热传递的面积。CACT开发了一种粘结技术，使用电弧喷涂方法，将金属网、泡沫和穿孔板粘结到管上。我们将在各种应用中使用高效热交换器，包括废热回收、燃气加热器和工业烤箱。
