DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0036] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0037] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0038] See also Figure 1 As shown, according to an embodiment of the present invention, the energy recovery device includes a cover body 1, a heat conductor 2 and a power generation component; the cover body 1 is arranged outside the heating element, and the cover body 1 includes at least one heat absorption layer 101; one end of the heat conductor 2 is connected to the heat absorption layer 101, and the other end of the heat conductor 2 is connected to the power generation component, and the power generation component is used to generate electricity using the heat transferred by the heat conductor 2.

[0039] The cover 1 is placed outside the heating element. During the operation of the heating element, the load on the heating element increases, generating a large amount of heat. The heat absorption layer 101 absorbs the generated heat. Since the heat conductor 2 is connected to the heat absorption layer 101, the heat is transferred to the heat conductor 2. The heat conductor 2 then transfers the heat to the power generation component, which fully utilizes the heat transferred from the heat conductor 2 to generate electricity. During the operation of the heating element, noise is also generated. The cover 1 can be used to soundproof it. The utility model can simultaneously reduce noise and absorb heat by providing the cover 1, thereby reducing the impact of the noise of the heating element on the environment and the impact of heat on the working efficiency of the heating element. It can also fully utilize the absorbed heat to achieve secondary use of heat.

[0040] It is worth noting that in this embodiment, the heat conductor 2 is a solid rod made of a metal material with good thermal conductivity, such as silver, copper, and aluminum. It can be sandwiched with copper wire with even better thermal conductivity to facilitate rapid heat transfer. According to heat transfer theory, as long as there is a temperature difference within an object, heat will be transferred from the high-temperature part of the object to the low-temperature part, or when there is a temperature difference between objects, heat will spontaneously transfer from the high-temperature object to the low-temperature object. In this embodiment, the heating element is a heat source. Since the heating element is enclosed in the housing 1, as the temperature within the housing 1 gradually increases, heat will be transferred to the heat absorption layer 101. As the temperature of the heat absorption layer 101 gradually increases, the heat will gradually be transferred to the heat conductor 2, and the heat conductor 2 will then transfer it to the power generation component.

[0041] See also Figures 1 to 5 As shown, the cover body 1 includes two heat absorbing layers 101 , a liquid layer is provided between the two heat absorbing layers 101 , and the heat conducting element 2 is connected to the outer heat absorbing layer 101 .

[0042] Thermal conduction refers to the transfer of heat between parts of an object with different temperatures, or between two objects with different temperatures, through the thermal motion of microscopic particles such as electrons in molecules and atoms. Thermal conduction is a property of matter and can occur in solids, liquids, and gases. In this example, two heat-absorbing layers 101 are provided: one is the outer layer, and the other is the inner layer. The inner layer 101 is located near the heat-generating element. The inner layer 101, the liquid layer, and the outer layer 101 form a three-layer sandwich structure. In this embodiment, the temperature of the air in the cover body 1 first rises, the inner heat absorption layer 101 contacts the hot air, the temperature of the inner heat absorption layer 101 first rises, the inner heat absorption layer 101 contacts the liquid layer, the temperature of the inner heat absorption layer 101 rises and then transfers the heat to the liquid layer, the liquid layer contacts the outer heat absorption layer 101, the temperature of the liquid layer rises and then transfers the heat to the outer heat absorption layer 101, and the outer heat absorption layer 101 then transfers the heat to the heat conductor 2.

[0043] The liquid layer in this embodiment is a layered structure formed by filling it with liquid and then vacuuming it. Once the housing 1 is installed and the heating element is operating, the air temperature within the housing 1 increases. The inner heat-absorbing layer 101 absorbs heat and transfers it to the liquid layer, causing the liquid in the liquid layer to heat up. The outer heat-absorbing layer 101 absorbs the heat from the liquid, gradually increasing its temperature as well. Liquid has a higher thermal conductivity and noise reduction effect than air, allowing it to absorb heat more quickly and to the greatest extent possible.

[0044] In a specific embodiment, the inner heat-absorbing layer 101 has a wavy structure, that is, the surface closest to the heating element is wavy. This wavy surface increases the contact area with the noise and heat generated by the heating element during operation, thereby maximizing noise reduction and heat absorption. Preferably, the outer heat-absorbing layer 101 has a smooth surface, but it can also have a wavy surface.

[0045] As a specific embodiment, the heat absorption layer 101 is made of sheet metal with good thermal conductivity. In order to avoid heat loss from the sheet metal, it is preferred to provide an insulation layer on the outer heat absorption layer 101 to reduce heat loss during the heat transfer process and enable more heat to be concentratedly transferred to the heat conductor 2.

[0046] Specifically, the thermal insulation layer is made of thermal insulation materials such as asbestos, mineral silica wool, diatomaceous earth, expanded perlite and ultra-fine ground glass wool, and the thermal insulation materials are porous structural materials with pores filled with air.

[0047] See also Figure 5As shown, the housing 1 is formed by a heat shield 11, a top cover 12, and a bottom plate 13. The heat shield 11 and the top cover 12 each include a liquid layer and at least two heat-absorbing layers 101. The top cover 12 is connected to the top of the heat shield 11, and the bottom plate 13 is connected to the bottom of the heat shield 11. Preferably, the bottom plate 13 and the heat shield 11 are connected by screws, and the bottom plate 13 is used to place the compressor.

[0048] See also Figure 5 and Figure 6 As shown, the heat shield 11 includes a first heat shield 111, a second heat shield 112 and a third heat shield 113 that are interconnected. One side of the first heat shield 111, the second heat shield 112 and the third heat shield 113 is respectively provided with a mounting groove 114, in which a first magnetic block is embedded, and the other side is respectively provided with a corresponding second magnetic block 115, which is embedded in the mounting groove 114.

[0049] In this embodiment, the side walls of the first, second, and third insulation panels 111, 112, and 113 are interconnected. When used in an outdoor unit 6, the circuitry of the outdoor unit 6 generates mutual magnetism with the impulse and potential energy of the first and second magnetic blocks 115. Before installing the heat shield 11, the first and second magnetic blocks 115 are separated. To install the heat shield 11, the corresponding second magnetic blocks 115 are aligned with the mounting slots 114. Once the circuit is established, the first and second magnetic blocks 115 are attracted to each other, and the second magnetic blocks 115 are embedded in the mounting slots 114. When the heat shield 11 is removed, the first and second magnetic blocks 115 are no longer attracted to each other, and the insulation panels are separated. In this embodiment, the first and second magnetic blocks 115 and the mounting slots 114 are arranged to secure and release the heat shield 11, facilitating installation and removal of the shield body 1 and preventing the panels from loosening during use.

[0050] See also Figure 7 As shown, as a specific embodiment, the top cover 12 can be connected to the heat shield 11 by screws. Preferably, the top of the heat shield 11 is provided with a mounting groove 114 and a first magnetic block embedded therein, and the bottom of the top cover 12 is provided with a second magnetic block 115. That is, the top cover 12 and the heat shield 11 are also connected by magnetic attraction, which facilitates the removal and installation of the top cover 12.

[0051] See also Figure 8 and Figure 9 As shown, the housing 1 is provided with a through hole 102 for the passage of a pipeline. A retractable or expandable blade assembly 4 is provided at the through hole 102. The diameter of the blade assembly 4 when retracted is the same as the outer diameter of the pipeline 3 of the heating element, and the diameter of the blade assembly 4 when expanded is larger than the outer diameter of the pipeline 3 of the heating element. When the heating element is a compressor, the through hole 102 is opened on the top cover 12 according to the exhaust of the compressor pipeline.

[0052] In this embodiment, the heating element is connected to a pipeline that needs to extend out of the housing 1. After the heating element is placed on the base plate 13, the heat shield 11 is connected to the base plate 13, the pipeline extends out of the through hole 102, and the top cover 12 is connected to the heat shield 11. The blade assembly 4 is retracted, and the blade assembly 4 wraps around the pipeline. Before removing the top cover 12, the blade assembly 4 is unfolded and stored in the top cover 12. Due to the gap between the pipeline and the top cover 12, the diameter of the blade assembly 4 is reduced when it is retracted, wrapping around the pipeline 3 of the heating element. The provision of the blade assembly 4 can reduce the heat dissipation from the housing 1 to the outside of the housing 1, so that the heat is concentrated within the housing 1 to the greatest extent possible, thereby allowing more heat to be reused.

[0053] Preferably, the expansion and contraction of the blade set 4 is also controlled by the circuit of the outdoor unit 6, and the heating element is a compressor. That is, when the outdoor unit 6 is powered on, the compressor works and the blades are in a contracted state; when the outdoor unit 6 is powered off, the compressor stops working and the blade set 4 is expanded. In this way, the expansion and contraction of the blade set 4 can be achieved according to the working state of the outdoor unit 6.

[0054] As a specific embodiment, the blade group 4 includes a gear ring and a plurality of blade bodies spaced apart on the gear ring. The blade bodies can be driven and controlled by respectively setting small motors, or a connecting rod structure can be set. Each blade body is controlled by the same motor, and the motor can drive the blade body to rotate at different angles to realize the expansion and contraction of the blade group 4. This is the existing technology and will not be repeated here.

[0055] As a specific embodiment, the top cover 12 includes a first cover body and a second cover body that are detachably connected. The first cover body and the second cover body are connected by a snap or magnetic connection at the connection point between the first cover body and the second cover body. The use of a split connection between the first cover body and the second cover body facilitates the removal and installation of the top cover 12 by avoiding pipe connections.

[0056] The liquid layer is an electrorheological material, and the liquid layer can change the material density by changing the size of the liquid current.

[0057] In this embodiment, since the operating frequency of the heating element varies, the noise and heat generated also vary. Therefore, this embodiment fills the liquid with electrorheological material. By varying the current flowing through the electrorheological material, and thereby varying its density, the noise reduction effect of the housing 1 can be improved in real time based on the operating frequency of the heating element. It is worth noting that adjusting the density of the electrorheological material is a prior art technique and will not be further elaborated here.

[0058] As a specific implementation method, refer to Figure 10As shown, the housing 1 includes two heat-absorbing layers 101, with a liquid layer disposed between the two layers. When the housing 1 includes a heat-insulating cover 11 and a top cover 12, the first, second, and third heat-insulating plates 111, 112, and 113 each include two heat-absorbing layers 101 and a liquid layer. Because the top cover 12 is provided with the blade assembly 4, the top cover 12 is provided with only two heat-absorbing layers 101, without a liquid layer. A certain space exists between the two heat-absorbing layers 101. When the blade assembly 4 is deployed, the blades themselves can extend in this space. The bottom plate 13 is a solid plate, without either a heat-absorbing layer 101 or a liquid layer.

[0059] The device also includes a sensor, which is used to detect the noise level of the heating element, and the density of the liquid layer changes with the noise level.

[0060] As a specific embodiment, the heat-conducting element 2 can be fixedly connected to the heat-absorbing layer 101 of any one of the first heat insulation board 111, the second heat insulation board 112 and the third heat insulation board 113, and the liquid layers between the partitions are not connected. The noise level of the heating element can be detected by setting a sensor, thereby changing the density of the electrorheological material. Each partition is a separate detection system, which is jointly coordinated and controlled by the outdoor unit 6 system.

[0061] It is worth noting that, because the housing 1 is relatively sealed, the heat-absorbing layer 101 is evenly heated, and a single heat-conducting rod is sufficient for heat transfer. To accelerate heat transfer, multiple heat-conducting members 2 can be provided to conduct heat from each partition to the energy conversion device. Furthermore, the contact area between the heat-conducting members 2 and the partitions can be increased, allowing more heat to be transferred to the heat-conducting members 2.

[0062] In this embodiment, the heat conducting member 2 is preferably in the shape of a solid rod. The heat conducting member 2 may also be in the shape of a hollow structure. When the heat conducting member 2 is in the shape of a hollow structure, liquid may be injected into the interior thereof to improve heat conduction efficiency.

[0063] See also Figures 1 to 3 As shown, the power generation component includes an energy converter 51 and a generator 52. The inlet end of the energy converter 51 is connected to the heat conductor 2, and the outlet end of the energy converter 51 is connected to the generator 52. The energy converter 51 uses the heat conducted by the heat conductor 2 to generate steam.

[0064] In this embodiment, the housing 1 absorbs heat and transfers it to the heat conductor 2 via the heat absorption layer 101. Since the temperature of the heat conductor 2 also rises, the energy converter 51 can fully utilize the heat to generate steam. The steam generated by the energy converter 51 is then transported to the generator 52 for power generation. In this embodiment, the energy converter 51 is configured to convert heat into steam, which is then transported to the generator 52 for power generation, achieving secondary utilization of the heat.

[0065] See also Figure 10 As shown, the energy converter 51 includes a water tank 511 and a one-way valve 512. The heat conductor 2 is in contact with the water tank 511 or the heat conductor 2 is in contact with the liquid in the water tank 511. The water tank 511 is used to hold a low-boiling-point liquid. The water tank 511 is connected to the generator 52 through a first pipeline, and the one-way valve 512 is arranged on the first pipeline.

[0066] In this embodiment, the heat conducting member 2 can be connected to the water tank 511 or extended into the water tank 511 to contact the liquid. As the temperature of the heat conducting member 2 rises, the liquid evaporates to form steam, converting heat into steam. The generated steam passes through the one-way valve 512 to the generator 52. The one-way valve 512 accelerates the steam, accelerating its delivery and delivering a large amount of steam to the generator 52.

[0067] See also Figure 11 As shown, the power generation component also includes a steam recovery component 53, which includes a water collection tank 531 and a one-way flow device. The inlet of the water collection tank 531 is connected to the generator 52, and the outlet of the water collection tank 531 is connected to the water tank 511 through a second pipeline. The one-way flow device is arranged at the outlet of the water collection tank 531.

[0068] In this embodiment, the water collecting tank 531 is funnel-shaped. The steam generated by the evaporation of the liquid in the water tank 511 will be transported to the generator 52. After the generator 52 works to generate electricity, the steam is cooled in the funnel-shaped water collecting tank 531 and turned into liquid. The liquid is then transported to the water tank 511 through a one-way flow device. It is worth noting that the steam is mainly generated by liquid with a low boiling point. At this time, the recovered liquid is only used as a backup liquid or mixed with a liquid with a low boiling point to ensure that there is liquid in the water tank 511 that can evaporate.

[0069] The generator 52 is a steam turbine generator 52 , and the generator 52 is connected to an external energy storage device.

[0070] In this embodiment, generator 52 is a steam generator. After steam is delivered to generator 52, it passes through the vortex structure of the generator's outer casing, driving the rotation of the single-piece impellers on each layer of generator 52. Simultaneously, the multiple layers of single-piece impellers can reuse the steam multiple times, improving power efficiency. The multiple layers of impellers drive the motor to generate electricity, which can be stored in an external energy storage device or directly used in the outdoor unit 6 system.

[0071] See also Figure 12 and Figure 13 As shown, an outdoor unit 6 includes an energy recovery device, the energy recovery device is the above-mentioned energy recovery device, and the heating element is a compressor.

[0072] When the energy recovery device is used in the outdoor unit 6, the specific process is: 1) the cover 1 is installed, and the compressor is now located in the cover 1, and the space of the cover 1 is moderate, and it is adapted to the volume of the compressor as much as possible to allow heat to be more concentrated; 2) the blade group 4 shrinks to wrap the pipeline, the cover 1 reduces the noise of the compressor and absorbs heat through the heat absorption layer 101 and the liquid layer; 3) the heat conductor 2 transfers the heat to the energy converter 51, and the liquid with a low boiling point in the water tank 511 evaporates due to heat to produce steam; 4) the steam is transmitted to the generator 52, and the impeller of the generator 52 uses the steam to generate electricity, which acts on the outdoor unit 6 system, and the excess electricity is stored in an external energy storage device; 5) the steam after work is transported to the water collection tank 531 for cooling and recovery.

[0073] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are only preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and variations can be made without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
