一种用于加热水的热泵换热器

Heat exchanger of heating pump for heating water

Abstract

本发明公开了一种用于加热水的热泵换热器,包括內桶和外桶,所述內桶嵌套于外桶内部并且两者之间具有供水流动的水流通道,水流入口位于外桶的底部,水流出口位于外桶的顶部并且与水流入口分布于外桶的两侧;所述外桶的外周壁压制形成螺旋状沟槽,所述螺旋状沟槽内设有内部走制热工质的换热结构。有益之处在于:本发明的热泵换热器中,被加热的水和热泵工质完全逆流且流速较高,大幅度提升了换热器的换热效率,降低了结垢速度;换热器采用开放式结构,内桶、外桶可分解,便于实施清洗、除垢作业,确保换热效率和高温热水的卫生标准,为高温热泵热水器的大规模应用提供了有效的解决方案,节能效果显著。
The invention discloses a heat exchanger of a heating pump for heating water. The heat exchanger comprises an inner bucket and an outer bucket, wherein the inner bucket is embedded in the outer bucket; a water flow channel for water flow is formed between the inner and outer buckets; a water flow inlet is formed in the bottom of the outer bucket; a water flow outlet is formed in the top of the outer bucket; the water flow inlet and the water flow outlet are distributed at two sides of the outer bucket; a spiral groove is pressed in the outer peripheral wall of the outer bucket; and a heat exchange structure in which a heating work medium flows is arranged in the spiral groove. The heat exchanger of the heating pump for heating water has the beneficial effect that heated water and the work medium of the heating pump flow in a complete counter-current manner and the flow speeds are relatively high; the heat exchange efficiency of the heat exchanger is greatly improved; the scale formation speed is reduced; the heat exchanger adopts an open type structure, the inner and outer buckets can be detached and the washing and descaling operations can be conveniently realized, so that the heat exchange efficiency and the sanitary standard of high-temperature hot water are guaranteed, an effective solution for large scale application of a water heater of a high-temperature heating pump is provided and the energy-saving effect is remarkable.
