一种热交换组件

Abstract

本公开实施例中提供了一种热交换组件，包括：一换热器；第一进气口通过第一外部管道连接于待升温气源以引入待升温气，第二进气口通过第二外部管道连接于热源气源，以引入与待升温气热交换的热源气热交换的；第一出气口输出待升温气源热交换后的升温气；第一出气口连通于第三外部管道；一旁路管道，连通第一外部管道和第三外部管道，以引出待升温气源的分支气流与升温气混合；至少一旁路调节阀，设于旁路管道中，用于被设置开度以调节经混合后的升温气的温度。通过旁路管道使得热交换组件能够在不同负荷条件下保持稳定的热交换性能，同时通过调节旁路调节阀的开度，可以控制旁路管道中分支气流的比例，从而调节混合后的升温气的温度。
