摘要： A heat exchanger for use with a heat pump water heater, the heat exchanger including a first header, a second header, multiple heat exchange tubes extending between the first header and the second header, an inlet pipe connected to the first header, a discharge pipe connected to at least one of the first header and the second header, and a bulkhead positioned in the first header. Each of the heat exchange tubes is curved and includes a flat surface. The bulkhead is positioned such that a circuitous flow path is formed between the first header and the second header. The flow path is configured so that refrigerant flows from the first header to the second header through a first set of heat exchange tubes and then from the second header to the first header through a second set of heat exchange tubes.
摘要翻译：一种与热泵热水器一起使用的热交换器，所述热交换器包括第一集管，第二集管，在第一集管和第二集管之间延伸的多个热交换管，连接到第一集管的入口管，排出管连接到第一头部和第二头部中的至少一个，以及定位在第一头部中的隔板。每个热交换管是弯曲的并且包括平坦表面。隔板的定位使得在第一头部和第二头部之间形成有迂回的流路。流动路径被配置成使得制冷剂通过第一组热交换管从第一集管流向第二集管，然后通过第二组热交换管从第二集管传递到第一集管。

摘要： A pressurized solar water heater, which belongs to solar energy application technology field. The water heater comprises a water storage tank and a solar heat collection device with filling opening and liquid port. The bottom of the inner tank consists of a heat exchange cavity with water inlet and water outlet. The upper surface of the heat exchange cavity is coplanar with the bottom surface of the inner tank. Connect filling opening and return opening of the solar heat collection device to the water inlet and water outlet of the said heat exchange cavity separately, thus forming a cyclical loop. The structure of this invention is relatively simple, which is not reducing the water storage space of the inner tank. And as the high temperature water in the inner tank and heat exchange cavity has a upward trend and the low temperature water has a dropping trend, the upper coplanar surface connects with the water with the lowest temperature in the inner tank all the time and the lower surface connects with the water with the highest temperature in the heat exchange cavity all the time. Then the upper surface and lower surface of the coplanar surface have a maximum difference in temperature to obtain best heat exchange efficiency, increasing the hot water supply greatly.
摘要翻译：一种加压太阳能热水器，属于太阳能应用技术领域。热水器包括一个储水箱和一个带有开口和液体端口的太阳能集热装置。内罐的底部由具有进水口和出水口的热交换腔组成。热交换腔的上表面与内罐的底面共面。将太阳能热采收装置的充填开口和返回开口分别连接到所述热交换腔的进水口和出水口，从而形成循环回路。本发明的结构相对简单，不会减少内箱的储水空间。而内罐和热交换腔内的高温水呈上升趋势，低温水呈下降趋势，上共面与内箱最低温度的水连通，下层表面与热交换腔中最高温度的水连接。然后共面的上表面和下表面具有最大的温差，以获得最佳的热交换效率，大大增加了热水供应。
