(1)Water flow in the inner tube and refrigerant flow in gap between the inner and outter coil, to enhance turbulence intensity and heat transfer coefficient.
(2)Inner tube is high efficiency dual-healix finned copper pipes, and heat exchange surface is 4 times that of smooth pipe.
(3)Fin on the internal and external surface will increase the turbulence of water and refrigerant, which will increase the efficient of heat exchange.
(4)There is no welding point on the copper pipe, so it can make sure the system work stably for a long time.
(5)There is dead zone in the water passageway, water flow at a balance speed. And heat exchanger will not easyly get frozen at part area.
(6)Water gap is at the lowest position of heat exchanger, and that will be convinient for drain away water in cold weather.
(7)The compact structure will help save room for a system, and it is convinient to set other part of a system, so it can decline the overall dimension of all system.
