Technical Field

[0001] The utility model belongs to the technical field of air source heat pump heat dissipation, and in particular relates to a waste heat recovery device for a fan of an air source heat pump water heater. Background Art

[0002] Air source heat pump is a type of heat pump technology, known as "the transporter of nature's energy". It has multiple advantages such as low cost, easy operation, good heating effect, safety and cleanliness. Air source heat pump uses the energy in the air as the main power, drives the compressor to operate through a small amount of electricity to achieve energy transfer, and does not require complex configuration, expensive water intake, recharging or soil heat exchange system and special machine room. It can gradually reduce the large amount of pollutant emissions brought to the atmospheric environment by traditional heating, and achieve the purpose of energy saving and environmental protection while ensuring heating efficiency.

[0003] Air energy (source) heat pump is driven by an electric motor, using the working principle of vapor compression refrigeration cycle, and using ambient air as the cold (heat) source to produce cold (hot) air or cold (hot) water. The main components include heat exchange equipment on the hot side, heat exchange equipment on the heat source side, and compressors. Air energy (source) heat pump uses the heat in the air as a low-temperature heat source, exchanges heat through the condenser or evaporator in the traditional air conditioner, and then extracts or releases heat energy through the circulation system, and uses the unit circulation system to transfer energy to the building to meet users' needs for domestic hot water, floor heating or air conditioning.

[0004] However, air source heat pump hot air blower has many application disadvantages in daily use. The heat pump hot air blower runs in a high temperature environment for a long time, so its own heat dissipation will be affected to a certain extent, resulting in the heat generated by itself cannot be dissipated in time, which will affect the service life of the air source heat pump hot air; for this reason, we propose an air source heat pump water heater fan waste heat recovery device. Summary of the invention

[0005] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an air source heat pump water heater fan waste heat recovery device, which solves the problem that the existing pump heat blower runs for a long time in a high temperature environment and the heat generated by itself cannot be dissipated in time.

[0008] Furthermore, one end of the heat exchange tube is connected to a first valve body, and the other end thereof is connected to a second valve body, and both the first valve body and the second valve body are connected to a quick connector.

[0009] Furthermore, the connecting component is a screw rod, which passes through a first fixing plate provided on the first heat dissipation body and slides inside the first fixing plate, and the other end of the screw rod is threadedly connected to a second fixing plate provided on the second heat dissipation body.

[0010] Furthermore, the connecting assembly includes a screw, a compression spring and a butterfly nut; the compression spring is sleeved on the outside of the screw, and the compression spring is located on the side of the first fixing plate away from the second fixing plate, one end of the compression spring contacts the first fixing plate, and the other end of the compression spring contacts the lower part of the butterfly nut.

In specific use, in order to improve the cooling efficiency of the refrigerant, the cooling heat exchange tube 3 is connected in parallel with the heat pump evaporator through the second valve body 5 and the first valve body 4.
