HEAT EXCHANGER

摘要

PURPOSE: A heat exchanger is provided to improve protection against heat and to prevent foreign materials from being attached between heat radiation fins. CONSTITUTION: A heat exchanger comprises a board-shape tube(10) and a heat radiation fin(20). The board-shape tube includes an internal flow path in which refrigerant fluid flows and forms layers. The heat radiation fin is arranged between board-shape tubes. The board-shape tube and heat radiation fin are made of an aluminum material and are combined by welding.
