Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, in particular to an axial flow fan for a heat pump unit. Background Art

[0002] A heat pump unit, also known as an air source heat pump, is a central air conditioning unit that uses air as the cold and heat source and water as the cooling and heating medium to meet the year-round cooling and heating needs of buildings or process systems. The axial flow fan is an important component of the heat pump unit.

[0003] However, the prior art still has shortcomings. The axial flow fan in the prior art is only protected by a single protective cover, which can only block large debris but cannot block small dust, resulting in the need for frequent cleaning of the heat exchanger, which increases the workload.

[0004] Therefore, we propose a heat pump unit with an axial flow fan to solve this problem. Utility Model Content
