The invention discloses a fin type indoor air temperature regulation product. The contact area between the product and air is much larger than the contact between the production and a common air conditioning heat exchanger, and the fin type indoor air temperature regulation product is even and quick in heat exchange and can achieve good heat transfer and exchange effects without large temperature difference. Even if the fin type indoor air temperature regulation product is used for refrigeration in summer, no condensed water is produced in a room, and the phenomenon that local places are damp and bacteria are bred due to water dropping does not exist. The fin type indoor air temperature regulation product can be installed indoors in various modes, can be hung on a wall to be a wall-mounted product, can stand on a floor to be a floor cabinet type product, can be embedded into a roof to be a ceiling type product and can be suitable for various occasions including home, vehicles, industry and the like.
