heat-exchanger是什么意思（中文）：热交换器，也称为换热器，是一种用于传递热量的设备。它通常由管道和壳体组成，通过这些管道流动的流体可以与壳体中流动的另一种流体进行热量交换。热交换器广泛应用于工业生产、空调、汽车发动机等领域。

heat-exchanger的意思（英文）：A heat exchanger, also known as a heat transfer device, is a piece of equipment used for transferring heat. It usually consists of pipes and a shell, through which one fluid flows and exchanges heat with another fluid flowing through the shell. Heat exchangers are widely used in industrial production, air conditioning systems, automobile engines, and other fields.

怎么读（音标）：[hiːt ɪksˈtʃeɪndʒə]

用法：heat-exchanger是一个可数名词，它可以单独使用，也可以作为其他词汇的修饰语。："The factory installed a new heat-exchanger to improve efficiency." （工厂安装了一个新的热交换器来提高效率。）
