Penukar haba sirip plat is a type of penukar haba design that uses plates and finned chambers to transfer haba between fluids, most commonly gases. It is often categorized as a compact heat exchanger to emphasize its relatively high pemindahan haba surface area to volume ratio. The plate-fin heat exchanger is widely used in many industries, including the aeroangkasa industry for its compact size and lightweight properties, as well as in kriogenik where its ability to facilitate heat transfer with small temperature differences is utilized.
Penukar haba sirip plat aloi aluminium, sering dirujuk sebagai Penukar Haba Aluminium Brazed, telah digunakan dalam industri pesawat selama lebih daripada 60 tahun dan diterima pakai ke dalam industri pengasingan udara kriogenik sekitar masa perang dunia kedua dan tidak lama selepas itu ke dalam proses kriogenik dalam loji kimia seperti Pemprosesan Gas Asli. Ia juga digunakan dalam enjin kereta api dan kereta bermotor. Sirip plat keluli tahan karat telah digunakan di dalam pesawat selama 30 tahun dan kini semakin mantap di kilang kimia.
