Description

Technical Field

[0001] The invention relates to the technical field of pumping system accessories, and in particular to a heat preservation and energy-saving device utilizing waste heat of an air compressor. Background Art

[0002] There are many existing design structures that can recycle the heat of air compressors. Most common waste heat utilization methods are to absorb and utilize the waste heat of air compressors through water cooling.

[0003] The structures of the water-cooling parts are mostly the same. They all install special water-cooling pipes on the outside of the air machine to absorb the waste heat generated by the air compressor through flowing liquid. The utilization process is also mostly similar. The liquid that absorbs the waste heat is discharged for utilization to achieve the needs of heat preservation and energy saving.

[0004] Traditional water cooling structures are mostly fixed in design, which continuously absorb the heat of the air compressor by continuously pumping in a single cooling liquid (usually water).

[0005] However, the heat around the air compressor is not constant. Under different working environments and different working powers, the heat around it will continue to change. The heat of the air compressor cannot be efficiently utilized through a single fixed water cooling structure, especially when the temperature is low. After water absorbs waste heat, the temperature rise range is limited, and this part of the heat is difficult to effectively utilize. By replacing the cooling liquid with a low-boiling point liquid, the waste heat at a lower temperature can be absorbed, but the low-boiling point liquid is easy to vaporize after absorbing heat, especially when the heat around the air compressor rises sharply, the low-boiling point liquid vaporizes in large quantities, causing the pressure in the cooling pipe to increase sharply, affecting the stability of the overall system.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Air compressors, also known as air machines, can use mechanical energy to compress air to meet the needs of cooling and heating. They are widely used in electrical equipment such as refrigerators and air conditioners.

[0032] When the air compressor is working, the density of the compressed air increases, and its internal temperature increases synchronously. At the same time, there is continuous friction in the air compressor during operation, which also generates a large amount of heat. Recycling this part of waste heat can achieve the purpose of heat preservation and energy saving.

[0033] There are many existing design structures that can recycle the heat of air compressors. Most common waste heat utilization methods are to absorb and utilize the waste heat of air compressors through water cooling.

[0034] The structures of the water-cooling parts are mostly the same. They all install special water-cooling pipes on the outside of the air machine to absorb the waste heat generated by the air compressor through flowing liquid. The utilization process is also mostly similar. The liquid that absorbs the waste heat is discharged for utilization to achieve the needs of heat preservation and energy saving.

[0035] Most traditional water-cooling structures are fixed in design, and the heat of the air compressor is continuously absorbed by continuously pumping in a single cooling liquid (usually water); however, the heat around the air compressor is not constant, and the heat around it will continue to change under different working environments and different working powers. The heat of the air compressor cannot be efficiently utilized through a single fixed water-cooling structure, especially when the temperature is low. After absorbing the waste heat, the temperature rise range of water is limited, and this part of the heat is difficult to effectively utilize; by replacing the cooling liquid with a low-boiling-point liquid, the waste heat at a lower temperature can be absorbed, but the low-boiling-point liquid is easy to vaporize after absorbing heat, especially when the heat around the air compressor rises sharply, the low-boiling-point liquid vaporizes in large quantities, causing the pressure in the cooling pipe to increase sharply, affecting the stability of the overall system.

[0036] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 8 A heat preservation and energy-saving device utilizing waste heat from an air compressor comprises a heat preservation shell 200 installed on the outside of an air compression component 300, wherein a heat exchange structure is installed inside the heat preservation shell 200, and the heat preservation shell 200 can wrap the air compression component 300 to achieve efficient heat preservation. Meanwhile, the heat exchange structure is installed inside the heat preservation shell 200, and the heat in the heat preservation shell 200 can be absorbed and converted in a centralized manner through the air compression component 300, and the waste heat emitted by the air compression component 300 in the heat preservation shell 200 can be efficiently utilized to achieve the purpose of energy saving and environmental protection; meanwhile, the temperature in the heat preservation shell 200 can be quickly absorbed through the heat exchange structure, so that the air compression component 300 can compress the air below a suitable temperature.

[0037] The heat-insulating shell 200 here is formed by a detachably connected lower shell 210 and an upper shell 220. Heat-insulating materials can be installed in the lower shell 210 and the upper shell 220 to improve the heat-insulating effect, avoid waste heat waste, and achieve efficient conversion and utilization of waste heat.

[0038] Specifically, during the air compression process, a high-temperature area and a low-temperature area are formed on the outside of the air compression component 300, and the high-temperature area is located on the side closer to the air compression component 300; the heat exchange structure includes a first heat exchange device 500 arranged in the high-temperature area, and the heat exchange structure also includes a second heat exchange device 600, and the second heat exchange device 600 can be moved in the high-temperature area and the low-temperature area; by arranging the first heat exchange device 500 and the second heat exchange device 600, the waste heat in the insulation shell 200 can be absorbed and utilized in a coordinated manner to achieve the purpose of cooling the insulation shell 200; at the same time, the second heat exchange device 600 can move in the high-temperature area and the low-temperature area to meet the insulation and energy-saving requirements under different temperature conditions in the insulation shell 200.

[0039] A normal temperature boiling point heat exchange medium flows inside the first heat exchange device 500, and a low temperature boiling point heat exchange medium flows inside the second heat exchange device 600. The boiling point of the normal temperature boiling point heat exchange medium is higher than that of the low temperature boiling point heat exchange medium, that is, the low temperature boiling point heat exchange medium in the second heat exchange device 600 is more sensitive to temperature and can absorb and utilize lower temperatures. However, the low temperature boiling point heat exchange medium absorbs heat and vaporizes at a higher temperature, causing excessive pressure in the second heat exchange device 600 and poor overall system stability. At the same time, after the second heat exchange device 600 is vaporized, the density of the low temperature boiling point heat exchange medium in the second heat exchange device 600 is reduced, thereby limiting the efficiency of absorbing excess waste heat.

[0040] In order to solve the above problems, when the temperature in the high-temperature area is lower than the set threshold, the second heat exchange device 600 is controlled to move to the high-temperature area to improve the heat exchange efficiency. At this time, the second heat exchange device 600 is moved to the high-temperature area, which can efficiently absorb and utilize the waste heat after the temperature is reduced, thereby improving the efficiency of waste heat absorption, conversion and utilization; when the temperature in the high-temperature area is higher than the set threshold, the second heat exchange device 600 is controlled to move to the low-temperature area, and the flow rate of the normal temperature boiling point heat exchange medium in the first heat exchange device 500 is increased. At this time, the second heat exchange device 600 is controlled to move to the low-temperature area outside to avoid the second The heat exchange device 600 continuously absorbs excess heat, causing its internal pressure to be excessive, thereby ensuring the stability of the overall system; at the same time, the position of the second heat exchange device 600 can be used as a detection unit, and the flow rate of the normal temperature boiling point heat exchange medium in the first heat exchange device 500 can be adjusted according to the moving position of the second heat exchange device 600. When the temperature increases, the flow rate of the normal temperature boiling point heat exchange medium is increased, and more normal temperature boiling point heat exchange medium can be pumped in to absorb excess waste heat, thereby ensuring the stability of the temperature in the insulation shell 200 and ensuring that the air compression component 300 compresses air within the rated temperature range.

[0041] It should be noted here that the temperature in the high-temperature area and the low-temperature area is a relative value, and it is not in a normal and unchanging state. When the working power of the air compression component 300 and the temperature of the compressed air increase, the temperature of the high-temperature area and the low-temperature area increase simultaneously, and vice versa. The temperature of the high-temperature area and the low-temperature area decreases simultaneously; generally speaking, the high-temperature area is located closer to the surface of the air compression component 300.

[0042] It should also be noted that the first heat exchange device 500 and the second heat exchange device 600 are independently designed heat exchange structures, each of which has a pump body for pumping liquid and a circulation structure independently designed therein, so as to independently and continuously absorb and utilize waste heat efficiently.

[0043] In summary, through the above-mentioned structural design, the combination of the first heat exchange device 500 and the second heat exchange device 600 can efficiently absorb and utilize the waste heat in the insulation shell 200; by designing the combination of normal temperature boiling point heat exchange medium and low temperature boiling point heat exchange medium, the waste heat outside the air compression component 300 under different conditions can be absorbed and utilized, while ensuring the heat dissipation requirements of the air compression component 300, the waste heat absorption and utilization efficiency is maximized; and the second heat exchange device 600 can be moved to the low temperature area after the high temperature around the air compression component 300, avoiding excessive pressure in the second heat exchange device 600 due to excessive temperature, avoiding local damage, and ensuring the stability and durability of the overall system. After the second heat exchange device 600 moves to the low temperature area, the flow rate of the normal temperature boiling point heat exchange medium in the first heat exchange device 500 increases, which can efficiently absorb the waste heat while avoiding the temperature in the low temperature area from rising above the warning value, further ensuring the normal operation of the air compression component 300 and the heat exchange structure as a whole.

[0044] Specifically, the first heat exchange device 500 is sleeved on the outside of the air compression component 300, and the first heat exchange device 500 and the air compression component 300 are eccentrically arranged in the heat preservation shell 200. A first installation area with a larger space is formed between the first heat exchange device 500 and the air compression component 300 and the inner wall of the heat preservation shell 200. The second heat exchange device 600 is located in the first installation area. By eccentrically designing the air compression component 300 and the first heat exchange device 500, a first installation area with a larger space can be formed in the heat preservation shell 200. Without adjusting the size of the heat preservation shell 200, the temperature difference between the high temperature area and the low temperature area can be made larger. When the temperature difference is larger, the temperature detection accuracy is higher. At the same time, the movable range of the second heat exchange device 600 is larger, which satisfies the efficient absorption of waste heat by the second heat exchange device 600, and can further avoid excessive pressure in the second heat exchange device 600 caused by excessive temperature, avoid local damage, and ensure the stability and durability of the overall system.

[0045] Furthermore, the second heat exchange device 600 includes a heat exchange body 610 and a driving body 620 for driving the heat exchange body 610 to move. The driving body 620 controls the heat exchange body 610 to move in a high temperature area and a low temperature area. The low-temperature boiling point heat exchange medium is located in the heat exchange body 610 and flows. The driving body 620 can control the heat exchange body 610 to move in the high temperature area and the low temperature area, thereby meeting the driving adjustment requirements. The driving body 620 here and the existing electrically controlled driving elements can also utilize the vaporization expansion of the low-temperature boiling point heat exchange medium to adjust the position of the heat exchange body 610.

[0046] The heat exchange body 610 here includes a mounting base 611 and a heat exchange pipe 612. The heat exchange pipe 612 is installed on the side wall of the mounting base 611 and extends along the axial direction of the air compression component 300. The mounting base 611 is slidably connected to the inner wall of the insulation shell 200, which can ensure the stability of the installation of the heat exchange pipe 612; the low-temperature boiling point heat exchange medium flows in a direction in the heat exchange pipe 612, and the heat exchange medium with a directional flow can efficiently absorb and utilize the waste heat.

[0047] The heat exchange pipe 612 here can be designed according to the selection. It can be designed as a separate tube as shown in the figure. The advantage is that it is easy to manufacture and control, and the internal structure of the insulation shell 200 is slightly changed. It can also be designed in a serpentine bending state. The advantage is that it can increase the contact area between the heat exchange medium and the waste heat, and enhance the absorption and conversion effect of the waste heat.

[0048] Specifically; as a first embodiment of the driving body 620, the driving body 620 includes an elastic hydraulic telescopic device, which controls the linear movement of the heat exchange body 610, and the hydraulic telescopic device is connected to the heat exchange body 610. The linear movement of the heat exchange body 610 can be controlled by hydraulic telescopic means. The hydraulic telescopic device is designed to be connected to the heat exchange body 610, and the low-temperature boiling point heat exchange medium inside the two can control the length of the hydraulic telescopic device to be telescoped, thereby realizing the control of the position of the heat exchange body 610.

[0049] When the low-temperature boiling point heat exchange medium in the heat exchange body 610 is heated, part of the liquid low-temperature boiling point heat exchange medium evaporates and becomes gaseous. At this time, the internal pressure of the hydraulic telescopic device increases, and the hydraulic telescopic device is controlled to extend or retract, thereby realizing the drive control of the position of the heat exchange body 610.

[0050] Through the above-mentioned structural design, the heat exchange body 610 itself can not only absorb waste heat, but also play the role of temperature detection and drive control; when the temperature in the high-temperature area rises, the low-temperature boiling point heat exchange medium in the heat exchange body 610 can be automatically controlled to evaporate, and the evaporated low-temperature boiling point heat exchange medium can be used as a power source to drive the hydraulic telescopic device to move, thereby realizing automatic detection and drive control process, simplifying the internal structure and control process, and there is no need to specially design a temperature detection unit and an adaptive electric control drive structure, with high control efficiency and good control stability.

[0051] Please refer to the attached Figure 7 And attached Figure 8 As a first embodiment of the hydraulic telescopic device, the hydraulic telescopic device includes an elastic telescopic bag 625, a first end of the telescopic bag 625 is connected to the heat exchange body 610, and a second end is connected to the inner wall of the heat insulation shell 200. A through opening 510 for the heat exchange body 610 to pass through is formed inside the first heat exchange device 500. The telescopic bag 625 is located on the side close to the high temperature area. The telescopic bag 625 is connected to the heat exchange body 610. The telescopic bag 625 is located on the side closer to the high temperature area. After the telescopic bag 625 is heated, the low-temperature boiling point heat exchange medium inside it vaporizes, causing the pressure in the overall system to increase. The telescopic bag 625 expands and extends, which can push the heat exchange body 610 to move toward the outside, push the heat exchange body 610 to move toward the low temperature area, control the temperature drop in the heat exchange body 610, and avoid excessive expansion of the telescopic bag 625.

[0052] At the same time, after the temperature in the high-temperature area drops, the bellows 625 is filled with liquid low-temperature boiling point heat exchange medium, and the pressure in the bellows 625 is reduced. Under the action of the bellows 625's own elasticity, the heat exchange body 610 can be pulled back as a whole and moved to the high-temperature area, thereby re-realizing efficient absorption of waste heat.

[0053] A guiding device is installed inside or outside the telescopic bag 625 to ensure that the telescopic bag 625 can expand and contract along a predetermined path, thereby meeting the control requirements of the heat exchange body 610.

[0054] Please refer to the attached Figure 4 And attached Figure 5As a second embodiment of the hydraulic telescopic device, the hydraulic telescopic device includes an elastic hydraulic telescopic rod, which is arc-shaped. The telescopic base 621 of the hydraulic telescopic rod is sealed and slidably connected with a control piston 622. The side wall of the control piston 622 is fixed with an arc-shaped telescopic end 624. A control chamber 623 is formed between the first side of the control piston 622 and the inner wall of the telescopic base 621. The control chamber 623 is connected to the heat exchange body 610. The control chamber 623 is still filled with a low-temperature boiling point heat exchange medium. By adjusting the pressure in the control chamber 623, the extension and retraction of the hydraulic telescopic rod can be controlled, and finally the position of the heat exchange body 610 can be controlled.

[0055] It should be noted here that the telescopic end 624 of the hydraulic telescopic rod is set toward the high-temperature area. When the hydraulic telescopic rod is extended, the heat exchange body 610 can be controlled to move to the inside of the high-temperature area, closer to one side of the air compression component 300, thereby achieving efficient absorption of waste heat.

[0056] At the same time, the control chamber 623 is located on the side close to the telescopic end 624, and the internal cross-section of the control chamber 623 is smaller. After the same volume of low-temperature boiling point heat exchange medium enters the control chamber 623, the telescopic end 624 can be controlled to shrink quickly, thereby realizing an efficient control process.

[0057] It should also be noted here that by designing the hydraulic telescopic rod to be arc-shaped, it can adapt to the circular chamber in the insulation shell 200, and effectively control the movement of the heat exchange body 610 between the high temperature area and the low temperature area; at the same time, an elastic element is installed in the hydraulic telescopic rod, which can control the hydraulic telescopic rod to reset under low temperature conditions, and the reset hydraulic telescopic rod is in a normally extended state.

[0058] Here, the arc-shaped hydraulic telescopic rod and the heat exchange body 610 can be designed as two groups, and the two heat exchange bodies 610 can be controlled separately at the two side positions to meet the requirements of efficient absorption and control of waste heat.

[0059] Please refer to the attached Figure 6 As a second embodiment of the driving body 620, the driving body 620 includes a traction roller 626, which is driven by an electric control device containing a temperature control unit. A first traction rope 627 is wound around the surface of the traction roller 626, and the first traction rope 627 is connected to the heat exchange body 610. A second elastic traction rope is connected between the heat exchange body 610 and the inner wall of the heat preservation shell 200. The second traction rope is a reset rope, which can control the heat exchange body 610 to reset to its initial position as a whole, that is, within the high temperature area.

[0060] During the driving process, the temperature in the high-temperature area is detected by the temperature control unit. When the temperature is too high, the electronic control device is controlled to drive the traction roller 626 to reel in. During the reeling of the traction roller 626, the heat exchange body 610 can be pulled toward the low-temperature area through the first traction rope 627 to achieve drive control. The above-mentioned driving method can still be selected as an electric slide rail, etc. By designing the traction roller 626, the heat exchange body 610 at different positions on both sides can be synchronously pulled by one traction roller 626 to achieve efficient synchronous control.

[0061] Furthermore, a positioning track 212 is opened on the inner wall of the insulation shell 200, and the heat exchange body 610 slides on the surface of the positioning track 212. A position detection component is arranged on the surface of the positioning track 212. A flow regulating component is arranged inside the first heat exchange device 500. The position detection component is electrically connected to the flow regulating component. The position detection component can send a control signal to the flow regulating component, thereby adjusting the flow rate.

[0062] The above-mentioned position detection component can select a position sensing element. When the heat exchange body 610 moves to the low temperature area, the flow rate in the first heat exchange device 500 is adjusted to increase to improve the efficiency of the first heat exchange device 500 in absorbing waste heat. Conversely, when the first heat exchange device 500 moves to the high temperature area, the flow rate in the first heat exchange device 500 is reduced, so that the first heat exchange device 500 and the heat exchange body 610 can fully absorb the waste heat, thereby improving the efficiency of waste heat absorption and conversion and achieving better thermal insulation and energy-saving effects.

[0063] Please refer to the attached Figure 2 And attached Figure 3 , further; a solid heat-conducting component 400 is installed on the surface of the air compression component 300, and the heat-conducting component 400 includes a heat-conducting ring 410 elastically rotatably connected to the air compression component 300 and a heat-conducting protrusion 420 fixed to the outer surface of the heat-conducting ring 410, and the heat-conducting protrusion 420 is located on the moving path of the second heat exchange device 600. The heat-conducting protrusion 420 is located on the moving path of the second heat exchange device 600, and the waste heat on the surface of the air compression component 300 can be conducted and concentrated through the heat-conducting ring 410 and the heat-conducting protrusion 420. In the process of the heat exchange body 610 of the second heat exchange device 600 moving toward the high-temperature area, the heat exchange body 610 can be pressed against the surface of the heat-conducting protrusion 420, and the waste heat can be quickly transferred between solids, further improving the effect of waste heat conversion, conduction and absorption.

[0064] Furthermore, it is preferred that the heat conductive component 400 is arranged in plurality, and the plurality of heat conductive components 400 are arranged along the axial direction of the air compression component 300, and the heat conductive protrusions 420 on the surface of the heat conductive component 400 are arranged according to different deflection orientations, and the plurality of heat conductive protrusions 420 can be arranged according to the same deflection angle. In the process of the heat exchange main body 610 moving toward the high temperature area, it can successively press against different heat conductive protrusions 420 to gradually improve the efficiency of waste heat exchange and improve the effect of the heat exchange main body 610 on absorbing waste heat.

[0065] Through the above-mentioned structural design, when the air compression component 300 generates less waste heat, the heat exchange body 610 moves toward the high-temperature area, and in the process of the heat exchange body 610 moving toward the high-temperature area, the number of the heat-conducting protrusions 420 pressed against the heat exchange body 610 gradually increases, so as to improve the effect of the heat exchange body 610 on absorbing waste heat; on the contrary, when too much waste heat is generated, the heat exchange body 610 is controlled to move toward the low-temperature area, and is out of contact with the multiple heat-conducting protrusions 420, thereby reducing the effect of waste heat conduction.

[0066] The present invention is further described below in conjunction with the method.
