Description

Technical Field

[0001] The utility model relates to the technical field of absorber spraying, and more specifically, to an absorber spraying device of an absorption heat pump. Background Art

[0002] The spraying device can evenly spray the absorption solution onto the heat transfer tubes of the absorber, ensuring that each heat transfer tube can fully contact the absorption solution, thereby improving the heat exchange efficiency. This uniform distribution avoids local overheating or overcooling phenomena, which is beneficial to the stability of the overall heat exchange process. Secondly, it can reduce the water flow impact. By optimizing the design of the spraying device, such as using segmented liquid inlet pipes and a dispersed arrangement of multiple spraying units, the impact of the water flow on the heat transfer tubes can be effectively reduced, and the phenomena of fluid rebound and splashing can be reduced, further improving the heat exchange efficiency.

[0003] After retrieval in the existing publicly disclosed technical literature, the patent with the Chinese patent publication number CN204063673U discloses an evaporator and absorber spraying device of an absorption heat pump. In this absorber spraying device, a plurality of shunt plates parallel to the heat exchange tubes are installed below the water spraying tray of the existing spraying device. In this way, the solution is sprayed onto the water spraying tray through the water spraying pipe, and then flows to the shunt plate through the water spraying holes of the water spraying tray. The shunt plate evenly drips the solution onto the central axis of the heat exchange tube through its guiding water outlet holes and flowing water strips. This improves the heat exchange efficiency of the evaporator and absorber, and further improves the heat exchange efficiency of the entire absorption heat pump. However, the following problems still exist when this absorber spraying device is in use.

[0004] During the process of spraying and cooling the absorber by the spraying device, it is necessary to achieve spraying and cooling through a specified position, and it is difficult to achieve large-area mobile cooling of the absorber. Moreover, the cooling is single-directional cooling, resulting in poor spraying and cooling effect of the absorber. Therefore, an absorber spraying device for an absorption heat pump is needed.
