Product feature

① High thermal exchange efficicieny

(1) Inner tube is high efficiency dual-healix finned copper;pipes, and heat exchange surface is 4 times that of smooth pipe.
(2) Fin on the internal and external surface will increase the turbulence of water and refrigerant, which will increase the efficient of heat exchange.
(3) With special process, the compact structure of heat exchange coiled pipe will well ensure the heat exchange between refrigerant and water.

② Safe

(1) There is no welding point on the copper pipe, so it can make sure the system work stably for a long time.
(2) 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.
3)Water gap is at the lowest position of heat exchanger, and that will be convinient for drain away water in cold weather.

③ Small

(1) 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.
(2) There is reservoir inside, and that will safe a lot of space for a system.

 

Application

Coil-in-shell heat exchanger is widely applied for: heat pump water heater, air source heat pump water heater,central air-conditioning,water source heat pump,swimming pool device, heat recovery system, heating, drying etc.

高效换热蒸发管

高效换热蒸发管在外表面上开有鱼鳞状的细槽,并在管表面下形成互相连通的环形通道,这种特殊的结构形成了优化设计的微孔,提供了蒸发换热所需的大量汽化核心点,又促使液体的汽化过程中形成效率极高的液膜蒸发,使气泡与管壁面的液膜减薄,减小了热阻,还能利用孔隙的毛细作用使液体及气泡在环形通道和孔内形成循环,有助于促进液体的内部对流和外部对流并且清除杂质和减轻结垢,利用这种换热管的特殊结构,冷媒在较小的过热度下就可以产生连续不断的气泡,蒸发传热系数可达光管的30倍以上;管的内表面加工出螺旋内翅,强化管内壁的换热,使总传热系数提高。

高效换热冷凝管

在冷凝器中冷凝换热现象是制冷剂蒸汽分子达到饱和温度附近时热量被带走,开始冷凝形成一层很薄的液膜,并逐渐变厚。高效换热冷凝管因翅片结构呈错开锯齿状,使冷凝液的流动呈扰动状态,促进冷凝液膜的对流传热。这种特殊的结构破坏了冷凝液膜的表面张力,使冷凝液膜更薄,并从翅片顶部快速流向环向分布的翅根部,并在重力作用下由翅根的微通道排放。内表面内翅可以强化内表面积和紊流二次流作用增大,进一步强化总换热能力。
