Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat recovery device for a heat pump unit. Background Technology

[0002] The waste heat recovery device of the heat pump unit is a high-efficiency and energy-saving equipment. With heat pump technology as the core, it recovers and reuses the low-grade waste heat that was originally wasted in industrial production and building heating and cooling processes. The recovered heat is then reused in production and daily life, which not only reduces the energy consumption costs of enterprises, but also reduces carbon emissions, which is in line with the green and low-carbon development trend. It has application prospects in the fields of industry, commercial buildings and hotels.

[0003] A search revealed Chinese patent publication number CN218495220U, which discloses a waste water and waste heat recovery device for heat pump units and its usage method. The device includes a recovery tank with an inlet pipe connected to the upper end, an outlet pipe connected to one side of the lower part, and a hot water pipe connected to one side. In this invention, hot water passes through a curved pipe. Due to the flow-guiding and obstructing effect of a guide plate, the time it takes for the high-temperature hot water to pass through the curved pipe is extended. When the high-temperature hot water is delivered to the nozzle seat, a booster pump pressurizes the hot water inside the nozzle seat through a delivery pipe, causing the hot water to be sprayed onto the upper end of a separation disc. Simultaneously, a motor drives the separation disc to rotate. The impact of the nozzle seat and the rotation of the separation disc improve the utilization efficiency of the high-temperature wastewater. With the help of the waste heat recovery components, the device achieves energy recovery and reuse, avoiding resource waste. However, in actual use, the fixed size of the device's connecting components makes it impossible to match the waste water outlet of heat pump units with different pipe diameters. This makes it difficult to directly connect heat pump units of different specifications to the device, limiting its application scope. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waste heat recovery device for heat pump units, aiming to improve the problem that it is difficult to directly connect heat pump units of different specifications to the device in the prior art, which limits the scope of application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat pump unit waste heat recovery device, including a heat pump unit box, a positioning mechanism is provided on the right side of the heat pump unit box, the positioning mechanism is used to adapt to the interface of different models of heat pump unit boxes, a conduit is connected to the right side of the heat pump unit box, and an air-cooling mechanism is provided outside the conduit, the air-cooling mechanism is used for wind energy heat exchange.

[0006] The positioning mechanism includes a flange one, the outer wall of which is fixedly connected to the right side of the heat pump unit box. A flange two is fixedly connected to the left side of the duct. Multiple connecting blocks are fixedly connected to the outer wall of the flange two. The outer walls of the multiple connecting blocks are all fixedly connected to the same outer ring. Multiple positioning blocks are slidably connected to the inner wall of the outer ring. An adjustment component is provided inside the outer ring. Limiting components are provided outside the multiple positioning blocks. A driving component is provided on the right side of the positioning block in the middle of the front side.

[0007] Through the above technical solution: flange one in the positioning mechanism is fixedly connected to the heat pump unit box, flange two is connected to the conduit, and multiple connecting blocks support and fix the outer ring, allowing the positioning blocks to slide within the outer ring. The drive component, adjustment component, and limit component cooperate with each other to drive all positioning blocks to move simultaneously toward or away from the center of the outer ring. The limit component restricts the movement range of the positioning blocks to ensure their precise sliding. This achieves adaptive positioning for flange interfaces of different specifications, enabling precise docking between the conduit and the heat pump unit box. This improves the versatility and installation efficiency of the device, avoids installation difficulties caused by different interface specifications, and ensures the stability and sealing of the connection.

[0008] As a further description of the above technical solution:

[0009] The air-cooling mechanism includes an inner cylinder, the inner wall of which is slidably connected to the outer wall of the duct, and multiple flow dividers are fixedly connected to the outer wall of the inner cylinder. The outer walls of the multiple flow dividers are all fixedly connected to the same flow guide shroud. The outer wall of the flow guide shroud is fixedly connected to two supports, and the inner wall of the flow guide shroud is fixedly connected to a fan.

[0010] Through the above technical solution: the fan is installed on the inner wall of the guide shroud and generates axial airflow when it is running. The guide shroud is fixed by a bracket, and the inner cylinder is sleeved on the outside of the duct and connected to the flow divider block. The flow divider block is also fixed to the guide shroud, forming an annular heat exchange area. The airflow blown out by the fan is guided by the guide shroud and then divided into multiple branches by the flow divider block. In the annular area, it fully contacts the outer wall of the inner cylinder for heat exchange. Through the cooperation of the fan, guide shroud, flow divider block and inner cylinder, efficient air cooling heat dissipation of the duct is achieved, the heat exchange efficiency in the waste heat recovery process is improved, and the temperature of the medium inside the duct is kept stable.

[0011] As a further description of the above technical solution:

[0012] The adjustment assembly includes multiple gears, the outer walls of which are rotatably connected to the left side of multiple connecting blocks, the outer walls of which are provided with multiple tooth grooves, and the outer walls of which are meshed with the same toothed ring.

[0013] Through the above technical solution: the gear in the adjusting component is rotatably connected to the connecting block, and its outer wall meshes with the tooth groove of the positioning block. At the same time, multiple gears mesh with the gear ring. When a positioning block moves, it drives the gear meshing with it to rotate. Through the gear ring transmission, all gears rotate synchronously, thereby driving all positioning blocks to move synchronously. This achieves synchronous adjustment of multiple positioning blocks and ensures the consistency and accuracy of flange interface positioning.

[0014] As a further description of the above technical solution:

[0015] Each of the multiple limiting components includes a shortest limiting block, and the outer walls of the multiple shortest limiting blocks are respectively fixedly connected to adjacent sides of the outer walls of the multiple positioning blocks. The outer walls of the multiple positioning blocks that are far apart from each other are each fixedly connected to a longest limiting block.

[0016] Through the above technical solution: the shortest limit block and the longest limit block of the limiting component are fixed on the adjacent and distancing sides of the positioning block, respectively. The shortest limit block prevents the positioning block from getting too close to collide, and the longest limit block prevents it from moving out of the effective range. The two work together to limit the movement trajectory and range of the positioning block, ensuring the stability and reliability of the positioning mechanism.

[0017] As a further description of the above technical solution:

[0018] The drive assembly includes a drive block, the outer wall of which is fixedly connected to the right side of the positioning block in the middle of the front side, and the inner wall of the drive block is threaded with a screw.

[0019] The above technical solution involves fixing the drive block of the drive assembly to the front center positioning block, and threading the screw to the drive block. When the screw is rotated, the drive block moves along the screw axis, thereby driving the positioning block to move. This provides a power source for adjusting the positioning block, enabling manual control of the positioning process. The operation is simple and the adjustment is precise.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the conduit is provided with a three-way valve, and the rear side of the three-way valve is connected to a discharge pipe.

[0022] The above technical solution involves installing a three-way valve on the conduit, with its rear end connected to the discharge pipe. By controlling the opening of the three-way valve, the high-temperature refrigerant can be switched between the waste heat recovery path and the direct discharge path. When waste heat recovery is not required, the high-temperature refrigerant is directly discharged through the discharge pipe, ensuring the normal operation of the heat pump unit and improving the flexibility of the device.

[0023] As a further description of the above technical solution:

[0024] The right side of the three-way valve is connected to a spiral coil heat exchanger, and a water storage tank is fixedly connected to the outer wall of the spiral coil heat exchanger.

[0025] The above technical solution involves connecting the right side of the three-way valve to a spiral coil heat exchanger. High-temperature refrigerant enters the heat exchanger through the three-way valve and exchanges heat with the external medium. The heated water is stored in a storage tank, realizing the recovery and utilization of waste heat from the heat pump unit. This converts heat into storable thermal energy for subsequent heating, improving energy efficiency and meeting users' hot water needs.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the screw is rotatably connected to the inner wall of the outer ring, and the outer walls of the plurality of positioning blocks are slidably connected to the outer wall of flange one on adjacent sides.

[0028] Through the above technical solution: the screw is rotatably connected to the inner wall of the outer ring, ensuring the stability of the screw during rotation; multiple positioning blocks are slidably connected to the outer wall of flange one on adjacent sides; when the positioning blocks move, their inner sidewalls tightly fit the outer side of flange one of different specifications, realizing precise positioning and clamping of flange one, ensuring accurate alignment of the duct and the flange interface of the heat pump unit box, facilitating subsequent connection.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the screw and drive block are driven by a threaded transmission, and the gear and gear ring are linked together, so that multiple positioning blocks can move synchronously and accurately along the radial direction, realizing automatic centering and clamping of flanges of different sizes, ensuring the docking of the duct and the heat pump unit. This allows the device to quickly complete the installation of waste heat recovery systems of different models of heat pump units without complicated adjustments, reducing labor costs and installation errors, while enhancing the system's sealing performance and operating efficiency, and extending the service life of the equipment.

[0031] 2. In this utility model, an axial airflow is generated by a fan and forms a directional flow through a guide shroud, so that the airflow can enter the heat exchange area in an orderly manner. The sliding and tight fit between the inner cylinder and the duct allows the heat on the surface of the duct to be transferred to the inner cylinder. The splitting and guiding of the airflow by the diverting block causes the tributary airflow to form turbulent motion in the annular area, which increases the contact area and time between the airflow and the inner cylinder, improves the heat exchange efficiency, and enhances the practicality and reliability of the waste heat reuse device.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] See attached document Figure 1 Appendix Figure 2 and attached Figure 4 An embodiment of this utility model is provided: a waste heat recovery device for a heat pump unit, including a heat pump unit box 1 for accommodating the heat pump unit, a positioning mechanism 2 on the right side of the heat pump unit box 1 for adapting to the interface of different models of heat pump unit box 1, a conduit 3 connected to the right side of the heat pump unit box 1 for transporting the high-temperature refrigerant generated by the heat pump unit, and an air-cooling mechanism 4 outside the conduit 3 for air energy heat exchange.

[0041] The positioning mechanism 2 includes a flange 201, the outer wall of which is fixedly connected to the right side of the heat pump unit box 1, serving as the connection base between the positioning mechanism 2 and the heat pump unit box 1. A flange 202 is fixedly connected to the left side of the conduit 3, connecting to the conduit 3 and providing an installation carrier for subsequent components. Multiple connecting blocks 203 are fixedly connected to the outer wall of flange 202, supporting the outer ring 204. The outer walls of all connecting blocks 203 are fixedly connected to the same outer ring 204, providing a sliding track for the positioning blocks 205. Multiple positioning blocks 205 are slidably connected to the inner wall of the outer ring 204, for fitting different... The outer wall of the flange of the same specification achieves precise positioning. An adjustment component 206 is installed inside the outer ring 204 to drive multiple positioning blocks 205 to move synchronously. The adjustment component 206 includes multiple gears 2061, the outer walls of which are rotatably connected to the left sides of multiple connecting blocks 203. This converts the displacement of a single positioning block 205 into the synchronous movement of multiple positioning blocks 205. The outer walls of each positioning block 205 have multiple toothed grooves 2062 for meshing with the gears 2061 to transmit motion. The outer walls of all the gears 2061 are meshed with the same toothed ring 2063 to ensure the synchronous rotation of multiple gears 2061. Each of the multiple positioning blocks 205 has a limit component 207 on its exterior to limit the movement range of the positioning blocks 205, ensuring positioning accuracy and stability. Each limit component 207 includes a shortest limit block 2071 to convert the displacement of a single positioning block 205 into synchronous movement of multiple positioning blocks 205. The outer walls of each positioning block 205 have multiple toothed grooves 2062 for meshing with the gears 2061 to transmit motion. The outer walls of the multiple gears 2061 are all meshed with the same toothed ring 2063. A toothed ring 2063 is used to ensure the synchronous rotation of multiple gears 2061. Limiting components 207 are provided on the outside of multiple positioning blocks 205 to limit the movement range of the positioning blocks 205 and ensure positioning accuracy and stability. A drive component 208 is provided on the right side of the front middle positioning block 205. The drive component 208 includes a drive block 2081, which is used to convert the rotational motion of the screw 2082 into linear motion. The screw 2082 is threadedly connected to the inner wall of the drive block 2081. The displacement of the drive block 2081 can be controlled by rotating the screw 2082, thereby realizing the adjustment of the positioning block 205.

[0042] Specifically, the positioning mechanism 2 is installed between the heat pump unit box 1 and the conduit 3 to achieve rapid positioning of flanges of different specifications. Flange 1 201 is fixed to the right side of the heat pump unit box 1. The conduit 3 is connected to the positioning mechanism 2 through flange 2 202. The connecting block 203 on the outer wall of flange 2 202 supports the outer ring 204. Multiple positioning blocks 205 are arranged in a ring and slide along the inner wall of the outer ring 204. When flange 1 201 of different specifications needs to be installed, positioning is achieved by operating the drive assembly 208. The screw 2082 is rotated, and the rotational motion is converted into linear displacement by its threaded connection with the drive block 2081. This drives the positioning block 205 fixed to the front middle of the drive block 2081 to move along the inner wall of the outer ring 204. The toothed groove 2062 on the outer wall of the positioning block 205 meshes with the gear 2061. When the positioning block 205 moves, the drive gear 2061 rotates around the fulcrum of the connecting block 203. Since multiple gears 2061 mesh with the gear ring 2063, the rotation of a single gear 2061 is transmitted through the gear ring 2063, so that all gears 2061 rotate synchronously, thereby driving the corresponding positioning block 205 to move towards or away from the center of the outer ring 204 at the same time. During the movement, the limiting component 207 plays a role. The shortest limiting block 2071 on the adjacent side of the positioning block 205 prevents the positioning block 205 from getting too close, and the longest limiting block 2072 on the opposite side prevents it from moving out of the effective range. When the positioning block 205 moves to the appropriate position, its inner wall is attached to the outer side of flange 201, completing the positioning and clamping, realizing the alignment of flange 202 and flange 201, which facilitates subsequent connection operations.

[0043] See attached document Figure 1 Appendix Figure 2 and attached Figure 5 The air-cooling mechanism 4 includes an inner cylinder 405. The inner wall of the inner cylinder 405 is slidably connected to the outer wall of the duct 3, which can closely fit the duct 3 and conduct heat, realizing the efficient transfer of heat from the duct 3 to the inner cylinder 405. Multiple flow dividers 404 are fixedly connected to the outer wall of the inner cylinder 405 to divide the airflow generated by the fan 403 into multiple branches, thereby increasing the contact area between the airflow and the inner cylinder 405. The outer walls of the multiple flow dividers 404 are all fixedly connected to the same flow guide shroud 401, which is used to constrain and guide the airflow direction, so that the airflow forms a directional flow in the annular area between the inner cylinder 405 and the flow guide shroud 401. Two brackets 402 are fixedly connected to the outer wall of the flow guide shroud 401 to securely install the flow guide shroud 401 on the external structure and counteract the vibration generated by the operation of the fan 403. The inner wall of the flow guide shroud 401 is fixedly connected to the fan 403, which serves as the power source of the air-cooling mechanism 4 and generates axial airflow to drive the heat exchange process.

[0044] Specifically, when the air-cooling mechanism 4 is running, the fan 403 starts to generate axial airflow, which is blown out through the outlet of the inner wall of the guide shroud 401. The cylindrical structure of the guide shroud 401 constrains the airflow, forming a directional flow. The diverting blocks 404 evenly distributed along the outer wall of the inner cylinder 405 divide the main airflow into multiple branches. Each branch diffuses at a specific angle along the guide surface of the diverting block 404 to the annular area between the inner cylinder 405 and the guide shroud 401. The inner cylinder 405 is slidably connected to the outside of the duct 3, which can effectively conduct heat from the surface of the duct 3. The branches in the annular area The airflow makes full contact with the outer wall of the inner cylinder 405 to achieve heat exchange, carrying away the heat absorbed by the inner cylinder 405 from the duct 3. At the same time, the splitting effect of the flow divider 404 causes the branch to form turbulence in the annular area, increasing the contact area and time between the airflow and the inner cylinder 405, and improving the heat dissipation efficiency. During operation, the flow guide shroud 401 is fixedly installed by the brackets 402 on both sides to maintain the stability of the mechanism, counteract the vibration generated by the operation of the fan 403, ensure that the air-cooling mechanism 4 dissipates heat continuously and efficiently, and ensure that the working temperature of the duct 3 is within a reasonable range.

[0045] See attached document Figure 1 Appendix Figure 3 and attached Figure 4 A three-way valve 5 is installed on the outer wall of the conduit 3 to control the flow direction of the high-temperature refrigerant and switch between the waste heat recovery path and the discharge path. The rear side of the three-way valve 5 is connected to the discharge pipe 6, which is used to directly discharge the high-temperature refrigerant when waste heat recovery is not required, so as to ensure the normal operation of the heat pump unit. The right side of the three-way valve 5 is connected to the spiral coil heat exchanger 7, which is used to transfer the heat of the high-temperature refrigerant discharged by the heat pump unit to the external medium to realize waste heat recovery and utilization. The outer wall of the spiral coil heat exchanger 7 is fixedly connected to the water storage tank 8, which is used to store the water heated by the heat exchanger for subsequent heating. The outer wall of the screw 2082 is rotatably connected to the inner wall of the outer ring 204. By rotating the screw 2082, the drive block 2081 can be driven to move axially, thereby controlling the position of the positioning block 205. The outer walls of multiple positioning blocks 205 are slidably connected to the outer wall of the flange 201 on adjacent sides. By adjusting the position of the positioning block 205, it can be adapted to different specifications of flange 201 to achieve precise positioning.

[0046] Specifically, the three-way valve 5 is connected to the spiral coil heat exchanger 7, which transfers the heat of the high-temperature refrigerant to the outside. Together with the water storage tank 8, it stores the heat energy, completes the effective recovery and utilization of waste heat, and meets the subsequent heating demand. In the positioning mechanism 2, the screw 2082 and the drive block 2081 are driven by threads, which are linked to multiple positioning blocks 205 through the gear 2061 and the gear ring 2063, so that they slide along the inner wall of the outer ring 204 and fit the flanges 201 of different specifications to achieve precise positioning. This ensures the compatibility of the device with the interfaces of various heat pump units and improves the versatility and practicality of the device.

[0047] Working principle: In the initial state, flange 201 of positioning mechanism 2 is fixed to the right side of heat pump unit box 1. Pipe 3 is connected to positioning mechanism 2 via flange 202. Multiple connecting blocks 203 on the outer wall of flange 202 jointly support the outer ring 204. Multiple positioning blocks 205 are arranged in a ring along the inner wall of the outer ring 204 and can slide radially. When different specifications of flange 201 need to be installed, the operator starts the positioning process. First, the drive assembly 208 is operated, rotating the screw 2082. Since the screw 2082 is threadedly connected to the inner wall of the drive block 2081, the screw... The rotation of rod 2082 is converted into linear displacement of drive block 2081. Drive block 2081 is fixed to the right side of front center positioning block 205. Therefore, front center positioning block 205 moves along the inner wall of outer ring 204 along with drive block 2081. The movement of positioning block 205 triggers the operation of adjustment component 206. Each positioning block 205 has multiple toothed grooves 2062 on its outer wall. These toothed grooves 2062 mesh with gear 2061. When a positioning block 205 starts to move, the gear 2061 meshing with it will start to rotate around the rotation fulcrum on the left side of connecting block 203. As multiple gears 2061 mesh with the gear ring 2063, the rotation of a single gear 2061 drives all gears 2061 to rotate synchronously through the transmission of the gear ring 2063. Each gear 2061 meshes with its corresponding positioning block 205, allowing all positioning blocks 205 to move simultaneously toward or away from the center of the outer ring 204. During the movement of the positioning blocks 205, the limiting component 207 plays a crucial guiding and limiting role. The shortest limiting block 2071 is fixed on the adjacent side of the outer wall of each positioning block 205, and the longest limiting block 2071 is fixed on the side furthest away. Positioning block 2072, the shortest limiting block 2071 can prevent positioning block 205 from getting too close to the center of outer ring 204 and avoid collisions, while the longest limiting block 2072 can prevent positioning block 205 from moving out of the effective sliding range of outer ring 204 and ensure that it always moves along the correct trajectory. When multiple positioning blocks 205 move to the appropriate position, their inner sidewalls will fit tightly against the outside of flange 1 201, completing the positioning and clamping of flange 1 201. At this time, flange 2 202 of conduit 3 and flange 1 201 of heat pump unit box 1 are precisely aligned, which facilitates subsequent bolt fastening connection operations.

[0048] Furthermore, when the air-cooling mechanism 4 is started, the fan 403 begins to operate, generating a strong axial airflow. The airflow first blows out from the fan 403 outlet on the inner wall of the guide shroud 401. Since the guide shroud 401 has a cylindrical structure, the airflow forms an initial directional flow inside it. At this time, the diverting block 404 plays a key role. Its evenly distributed shape along the outer wall of the inner cylinder 405 divides the main airflow blown out by the fan 403 into multiple branches. These branches diffuse along the guide surface of the diverting block 404 at a specific angle and direction to the annular area between the inner cylinder 405 and the guide shroud 401. As the multiple branches flow in the annular area, they interact with the airflow surrounding the duct 3. The inner cylinder 405 is in full contact with the outer wall of the side, and the inner cylinder 405 is tightly attached to the duct 3 through a sliding connection, which can efficiently transfer the heat on the surface of the duct 3. At this time, the tributary airflow exchanges heat with the outer wall of the inner cylinder 405, taking away the heat absorbed by the inner cylinder 405 from the duct 3. At the same time, due to the division and guiding effect of the flow divider 404 on the airflow, the tributary airflow forms a complex turbulent motion in the annular area, which further increases the contact area and contact time between the airflow and the inner cylinder 405, significantly improving the heat exchange efficiency. Throughout the process, the bracket 402 always keeps the guide shroud 401 stably installed, avoiding the vibration caused by the operation of the fan 403 from affecting the performance of the mechanism.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
