[0002] A heat pump is a highly efficient and energy-saving device that makes full use of low-grade heat energy. Heat can spontaneously transfer from a high-temperature object to a low-temperature object, but it cannot spontaneously transfer in the opposite direction. The working principle of a heat pump is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse circulation manner. It consumes only a small amount of net reverse circulation work to obtain a large amount of heat supply, and can effectively utilize low-grade heat energy that is difficult to apply to achieve the purpose of energy saving.

[0003] In existing heat pump systems, after the condenser releases heat, the heat energy is transported and used through heating pipes. However, during the transportation process, heat energy is lost, resulting in uneven medium temperature. Furthermore, dirt easily accumulates on the inner wall of the pipes during the medium flow. Utility Model Content

[0004] Therefore, it is necessary to provide a heat pump heating system to address the problems of heat loss and dirt accumulation on the inner walls of pipes.

[0005] A heat pump heating system includes a heat pump unit and a heat storage tank installed on its outer side, with a heating pipe between the heat pump unit and the heat storage tank; it also includes a flow guiding mechanism, which is disposed inside the heating pipe and is used to guide the high-temperature medium in different ways to reduce heat loss and reduce the accumulation of dirt inside the heating pipe; wherein, the flow guiding mechanism includes an outer ring disposed inside the heating pipe and a set of arc-shaped plates, the arc-shaped plates being installed on the inner wall of the outer ring, and a groove being disposed between two adjacent arc-shaped plates, and a set of inclined plates disposed inside the groove on the inner side of the outer ring.

[0006] In one embodiment, the flow guiding mechanism further includes an inner ring, the inclined plate is mounted to the outside of the inner ring, and the inner ring is coaxial with the outer ring and can rotate along its own axis.

[0007] In one embodiment, a set of inclined guide grooves are provided on the inner side of the inner ring, and the inclination of the guide grooves is less than that of the inclined grooves.

[0008] In one embodiment, a bracket is provided on the outer side of the inner ring, a set of metal blocks is provided on the outer side of the bracket, a fixing ring is sleeved on the outer side of the heating pipe, and a set of electromagnets is provided inside the fixing ring.

[0010] In one embodiment, a flow guide ring is installed on the side of the outer ring near the support, and both the flow guide ring and the inner ring have a tapered side view.

[0011] In one embodiment, the heat pump unit includes an evaporator assembly, a compressor, and a condenser, which are connected via a four-way valve.

[0012] In one embodiment, a circulation pump is provided on the outside of the thermal storage tank.

[0013] Beneficial effects 1. By setting up inclined troughs, some of the medium is guided in a spiral manner, forming a heat insulation layer during the medium flow process. At the same time, the medium flow rate is increased, reducing the phenomenon of excessive heat loss. The spiral flow mode can also increase the shear force and the mixing effect of the medium, impact cleaning the inner wall of the pipe, reducing the accumulation of dirt and uneven temperature. 2.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a heat pump heating system.

[0019] In one embodiment, a heat pump heating system includes a heat pump unit 100 and a heat storage tank 200 installed on its outer side, with a heating pipe 300 disposed between the heat pump unit 100 and the heat storage tank 200; it also includes a flow guiding mechanism 400, which is disposed inside the heating pipe 300 and is used to guide the high-temperature medium in different ways to reduce heat loss and reduce the accumulation of dirt inside the heating pipe 300; wherein, the flow guiding mechanism 400 includes an outer ring 410 disposed inside the heating pipe 300 and a set of arc plates 420, the arc plates 420 being installed on the inner wall of the outer ring 410, a groove 421 being disposed between two adjacent arc plates 420, and a set of inclined plates 411 disposed inside the groove 421 on the inner side of the outer ring 410.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the flow guiding mechanism 400 also includes an inner ring 430, and an inclined plate 411 is installed on the outside of the inner ring 430. The inner ring 430 and the outer ring 410 are coaxially arranged and can rotate along their own axis.

[0021] In this embodiment, during the heating process, the inner ring 430 divides the medium into two streams, an inner and an outer one. A small amount of medium on the outer side flows spirally through the inclined groove 421, traveling along the inner wall of the heating pipe 300 to insulate the large amount of medium on the inner side. Depending on the heating situation, the user can drive the inner ring 430 to move, causing the inclined plate 411 to move and changing the medium flow range of the inclined groove 421. This results in different flow rates and volumes of the medium flowing within the inclined groove 421, forming spiral insulation layers of varying strengths to meet different insulation and medium flow requirements.

[0022] It should be noted that the location and number of the flow guiding mechanism 400 can be selected according to the heating demand and the actual use of the heat pump unit 100 and the heat storage tank 200. The inclined plate 411 and the inclined groove 421 have the same inclination, which reduces the turbulence phenomenon before and after adjustment.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, an inclined guide groove 431 is provided on the inner side of the inner ring 430, and the inclination of the guide groove 431 is less than that of the inclined groove 421.

[0024] The outer side uses inclined groove 421 to form a strong spiral flow to ensure the stability of the protective layer, while the inner side uses guide groove 431 to form a conventional spiral flow to increase the flow velocity of the inner medium and shorten the flow time of the medium. It should be noted that since the inclination of the guide channel 431 is less than that of the inclined channel 421, the spiral flow intensity on the inner side is lower than that on the outer side. This ensures that while the medium flow rate is increased, it is not easy to impact and damage the outer protective layer, thus ensuring the thermal protection effect.

[0025] like Figure 2 and Figure 3 As shown, a bracket 432 is provided on the outer side of the inner ring 430, a set of metal blocks 433 is provided on the outer side of the bracket 432, a fixing ring 310 is sleeved on the outer side of the heating pipe 300, and a set of electromagnets 311 is provided inside the fixing ring 310.

[0026] The operation of the electromagnet 311 inside the fixed ring 310 causes the corresponding metal block 433 to be attracted and moved, thereby causing the bracket 432 to be driven and driving the inner ring 430.

[0027] like Figure 2 and Figure 3 As shown, the docking points of a group of metal blocks 433 and the bracket 432 are different, and a group of electromagnets 311 are evenly distributed along the axis of the fixing ring 310 and can be magnetically connected to the metal blocks 433.

[0028] Since the installation points of each metal block 433 are different, the corresponding electromagnet 311 can be used to operate, so that the corresponding metal block 433 is attracted and moved, thereby completing the inner ring 430 to different degrees and changing the blocking range of the inclined plate 411 on the inclined groove 421.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a guide ring 434 is installed on the side of the outer ring 410 near the bracket 432. Both the guide ring 434 and the inner ring 430 have a tapered side view.

[0030] By utilizing a conical design, the resistance experienced by the medium during the flow guidance process is reduced, thereby reducing energy consumption.

[0031] like Figure 5 As shown, the heat pump unit 100 includes an evaporator assembly 110, a compressor 120, and a condenser 130, which are connected by a four-way valve.

[0032] The heat pump heating method utilizes the evaporator assembly 110, compressor 120, condenser 130, and a four-way valve to complete the medium flow and heat supply. This is a mature existing technology and will not be described in detail here. It should be noted that the condenser 130 in this application is a plate heat exchanger. The outer wall of the copper tube of the plate heat exchanger is coated with a nano-hydrophobic coating to extend the frosting cycle. The compressor 120 in this application is a dual-rotor design, which is more efficient and has lower noise pollution. This dual-rotor design is a mature existing technology. Its internal structure and actual application will not be described in detail here. The evaporator assembly 110 includes a main evaporator and an auxiliary evaporator. The main evaporator adopts a microchannel parallel flow structure, and the auxiliary evaporator is a spiral coil type. The dual evaporator design can still maintain the preset heat under ultra-low temperature conditions.

[0033] like Figure 1 As shown, a circulation pump is installed on the outside of the heat storage tank 200.

[0034] Start the circulation pump to drive the medium in the heat storage tank 200 to circulate; It should be noted that the heat storage tank 200 is filled with paraffin-based phase change material.

[0035] Working principle: The heat pump unit 100 and the heat storage tank 200 are installed in the preset position. When heating is used, the heat energy is discharged from the heating pipe 300. During the flow of the medium, the medium is diverted by the guide groove 431 and inclined groove 421 inside and outside the inner ring 430. The outer side forms a medium insulation layer and the inner side forms a medium acceleration channel. During the heat energy transfer, the user can start the electromagnet 311 at the corresponding point to make the metal block 433 at the corresponding point move, which drives the inclined plate 411 and changes the flow range of the inclined groove 421, forming a spiral insulation layer of different strengths. Then the heat energy is introduced into the heat storage tank 200. Subsequently, the circulation pump is used to complete the circulation flow of the corresponding medium.

[0036] It should be noted that the heat pump unit 100 and electromagnet 311 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the heat pump unit 100 and electromagnet 311 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
