Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to an air source heat pump. Background Technology

[0002] Air source heat pumps, as devices that utilize heat from the air for heating or cooling, are widely used in many fields due to their energy-saving and environmentally friendly advantages. However, existing air source heat pumps still have room for improvement in heat exchange efficiency. Traditional heat exchanger designs are not sufficiently optimized, leading to incomplete heat transfer and a low overall energy efficiency ratio, increasing energy consumption and operating costs. Furthermore, some air source heat pumps exhibit poor adaptability to different climatic conditions, failing to meet users' needs for stable heating or cooling under extreme weather conditions. Utility Model Content

[0003] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0004] Specifically, the technical problem to be solved by this utility model is to provide an air source heat pump to solve the technical problems of low heat exchange efficiency and high energy consumption of existing air source heat pumps.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An air source heat pump includes a housing, within which a heat exchange assembly, a collection assembly, and a control assembly are disposed;

[0007] The heat exchange assembly includes multiple heat exchange tubes that are tightly wound in a spiral shape and fixedly installed inside the housing. Connecting pipes are installed on the heat exchange tubes, and conductive plates that are arrayed along their height are fixedly installed on the heat exchange tubes. Multiple heat dissipation fins are fixedly installed on the conductive plates.

[0008] As an improved technical solution, the heat dissipation fins are angular fins with fine textures on the surface.

[0009] As an improved technical solution, the collection component includes a guide plate fixedly installed on the conduction plate, a guide groove provided in the guide plate, a guide pipe connected to one end of the guide plate, and a storage tank fixedly installed in the outer shell connected to the end of the guide pipe.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the design of a double-helix heat exchange tube and heat dissipation fins, greatly increases the heat exchange area and simultaneously creates a complex flow path for the refrigerant within the tube, enhancing the heat exchange effect.

[0033] like Figures 1-5As shown in the figure, this embodiment provides an air source heat pump, which includes a housing 1, a heat exchange assembly 2 and a collection assembly 3, and a control assembly 4 inside the housing 1;

[0034] The heat exchange assembly 2 includes multiple heat exchange tubes 21 tightly wound in a spiral shape and fixedly installed inside the housing 1. Each heat exchange tube 21 is made of tightly wound copper alloy tubing, with highly thermally conductive nanoparticles incorporated into the copper to enhance its thermal conductivity. Connecting pipes 22 are connected to each heat exchange tube 21, and conductive plates 23, arranged in an array along its height, are fixedly installed on each heat exchange tube 21. Multiple heat dissipation fins 24 are fixedly installed on each conductive plate 23.

[0035] like Figure 5 As shown, the heat dissipation fin 24 is an angular fin. From the overall shape, it resembles a thin plate bent at a specific angle, presenting a sharp angular shape. The main body of the angular fin is relatively thin and light, made of high thermal conductivity aluminum alloy, which can ensure good thermal conductivity without increasing weight or occupying too much space due to excessive thickness. Its length is determined according to the specifications of the double helix structure heat exchange tube 21, and the surface has fine textures. These textures are formed in the process of precision die casting or stamping. They not only increase the roughness of the fin surface, which helps to generate more turbulence when the air flows, thus improving the heat dissipation effect, but also enhance the structural strength of the fin to a certain extent, preventing deformation during use. The corners of the angular fin can promote the formation of air turbulence. When the air flows over these corners, the airflow is dispersed to form small-scale turbulence areas, making the contact between the air and the fin surface more sufficient, thereby improving the heat dissipation coefficient. In addition, the multiple heat dissipation surfaces of the angular fins increase the total heat dissipation area, allowing heat to be transferred from the heat exchange tubes to the air more quickly, further improving heat exchange efficiency.

[0036] like Figure 2 Figure 5 As shown, the collecting assembly 3 includes a guide plate 31 fixedly mounted on the conduction plate 23, and the guide plate 31 is made of stainless steel. A guide channel 32 is provided inside the guide plate 31. The conduction plate 23 is inclined at an angle of 5-10 degrees. One end of the guide channel 32 and the other end of the guide pipe 33 are inclined at an angle of 10 degrees to ensure that the condensate can accurately flow into the storage tank 34. One end of the guide plate 31 is connected to the guide pipe 33, and the end of the guide pipe 33 is connected to the storage tank 34 fixedly mounted inside the outer casing 1.

[0037] like Figure 5 As shown, the conductive plate 23 and the heat dissipation fins 24 are provided with a hydrophobic layer 5 to prevent condensation from affecting the heat exchange efficiency.

[0038] like Figure 2 and Figure 4As shown, the control component 4 includes a flow regulating valve 41 fixedly installed on the connecting pipe 22. The intelligent flow regulating valve 41 can automatically regulate the refrigerant flow to ensure that the heat exchange process is always in optimal condition. A controller 42 is fixedly installed inside the housing 1. This invention also features an energy-saving compressor that uses variable frequency technology to automatically adjust its speed according to actual load requirements. During low-load operation, the compressor speed decreases, reducing energy consumption; during high-load operation, the compressor can quickly increase its speed to meet heating or cooling needs, thus achieving highly efficient and energy-saving operation of the entire system.

[0039] When the air source heat pump is in use, outdoor air is blown by a fan over the double-helix structure heat exchange tube 21 and heat dissipation fins 24 of the heat exchanger. The refrigerant flows inside the heat exchange tube 21 and exchanges heat with the outside air. The corners of the angular fins promote the formation of air turbulence. When the air flows over these corners, the airflow is dispersed to form small-scale turbulent areas, which makes the contact between the air and the fin surface more sufficient, thereby improving the heat dissipation coefficient. In addition, the multiple heat dissipation surfaces of the angular fins increase the total heat dissipation area, allowing heat to be transferred from the heat exchange tubes to the air more quickly, further improving heat exchange efficiency. Due to the design of the double helix structure and heat dissipation fins 24, as well as the functions of the hydrophobic layer 5 and the condensate collection assembly 3, a highly efficient and stable heat exchange process is achieved. When the air source heat pump is running, the collection of condensate ensures that the heat exchange surface remains relatively dry, reducing the increase in thermal resistance and maintaining high heat exchange efficiency. Furthermore, the refrigerant flow is automatically adjusted by the intelligent flow regulating valve 41, and the variable frequency compressor adjusts its speed according to the load demand, jointly ensuring the efficient and energy-saving operation of the system under different operating conditions.

[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
