Description

Technical Field

[0001] The present invention relates to the technical field of ultra-low temperature air heat pumps, and particularly to an ultra-low temperature air heat pump with quantitative flow guiding. Background Art

[0002] With the development of the economy, people's requirements for the quality of life are also getting higher and higher. Ultra-low temperature air heat pumps use the heat energy in the air to produce heat energy, and can provide different hot water and heating and cooling demands with large water volume, high water pressure, and constant temperature throughout the day. At the same time, they can consume the least amount of energy. The refrigerant is compressed by a compressor, and the temperature of the compressed refrigerant rises. The refrigerant after heat exchange in the condenser in the water tank is used to produce hot water, and the refrigerant after hot water exchange returns to the compressor for the next cycle. During this process, the air heat is absorbed by the evaporator and introduced into the refrigerant, and the refrigerant is then introduced into the water to produce hot water. The patent with the patent number CN218467882U discloses a mini air heat pump, including a pump body. An inner cover body is fixedly connected to the outside of the pump body. A dust filter net is fixedly connected to the front end of the inner cover body. An outer cover body is arranged in a circle outside the inner cover body. Two groups of connection ports are arranged through one side of the pump body. A water inlet pipe and a water outlet pipe are arranged on one side of the connection port. During the use of this mini air heat pump, it is necessary to inject refrigerant from the evaporator into the condenser. However, in the refrigeration system, the flow rate of the refrigerant is usually adjusted by a throttling device (such as a capillary tube or an electronic expansion valve), but these devices often cannot achieve precise flow control. Especially in complex working conditions, such as ultra-low temperature environments or variable working conditions, the fluctuation of the refrigerant flow rate causes the system performance to decline. In this way, due to the inaccurate control of the refrigerant flow rate, the refrigeration system will have problems such as low efficiency, compressor overload, or unstable refrigeration effect under certain working conditions. To solve the above problems, an ultra-low temperature air heat pump with quantitative flow guiding is proposed in the present invention. Summary of the Invention

Detailed implementation manners

[0064] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art in the field to which the present invention belongs. The words such as "including" used herein mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0065] In view of the problems existing in the prior art, the embodiments of the present invention provide a cryogenic air heat pump with quantitative diversion, as Figure 1 shown. A quantitative diversion mechanism 4 is added between the evaporator 2 and the condenser 3 in this embodiment, so as to ensure that the refrigerant can flow from the evaporator 2 to the condenser 3 quantitatively.

[0066] Specifically, the cryogenic air heat pump with quantitative diversion includes:

[0067] A heat pump housing 1; an evaporator 2 is arranged in the heat pump housing 1; a condenser 3 is arranged in the heat pump housing 1; a quantitative diversion mechanism 4 is arranged in the heat pump housing 1. The quantitative diversion mechanism 4 is arranged between the evaporator 2 and the condenser 3 and is used for connecting the evaporator 2 and the condenser 3. The quantitative diversion mechanism 4 is used to divert the refrigerant quantitatively from the evaporator 2 into the condenser 3.

[0068] In one implementation manner, asFigure 1 and Figure 2 As shown in Figure 2 , the metering and guiding mechanism 4 includes:

[0069] A metering and guiding pipe 41 is arranged between the evaporator 2 and the condenser 3, and both ends of the metering and guiding pipe 41 are fixedly connected to the outer side walls of the evaporator 2 and the condenser 3 respectively; both ends of a liquid inlet pipe 42 are connected to the evaporator 2 and the metering and guiding pipe 41 respectively, and the liquid inlet pipe 42 is used for communicating the evaporator 2 and the metering and guiding pipe 41; both ends of a liquid outlet pipe 43 are connected to the condenser 3 and the metering and guiding pipe 41 respectively, and the liquid inlet pipe 42 is used for communicating the condenser 3 and the metering and guiding pipe 41; a separating assembly 44 is arranged in the metering and guiding pipe 41, and the separating assembly 44 is used for separating the liquid inlet pipe 42 and the liquid outlet pipe 43; an intermittent blocking assembly 45 is arranged on the metering and guiding pipe 41, and the intermittent blocking assembly 45 is used for blocking the liquid inlet pipe 42 when a preset volume of refrigerant is stored in the metering and guiding pipe 41, so as to realize the quantitative control of the refrigerant.

[0070] Further, as Figure 2 shown in Figure 2 , the separating assembly 44 includes: a separating plate 441 is movably arranged in the metering and guiding pipe 41, and the separating plate 441 is in contact with the inner side wall of the metering and guiding pipe 41; a moving rod 442 is fixedly arranged on the side wall of the separating plate 441; a moving cylinder 443 is fixedly connected to the outer side wall of the condenser 3, and the moving cylinder 443 is movably sleeved outside the moving rod 442; a moving spring 444 is wound outside the moving rod 442, and both ends of the moving spring 444 are fixedly connected to the side wall of the moving rod 442 and the outer side wall of the moving cylinder 443 respectively.

[0071] During operation, the evaporator 2 injects refrigerant into the metering and guiding pipe 41 through the liquid inlet pipe 42 on the left side of the separating plate 441. As the amount of refrigerant increases (in this process, the refrigerant will not enter the condenser 3 through the liquid outlet pipe 43), it will push the separating plate 441 to move to the right. When the right side wall of the separating plate 441 contacts the liquid outlet pipe 43, the separating plate 441 will contact the intermittent blocking assembly 45. As the separating plate 441 continues to move to the right, it will push the intermittent blocking assembly 45 to block the liquid inlet pipe 42, preventing the refrigerant from continuing to enter the metering and guiding pipe 41, so that the refrigerant in the metering and guiding pipe 41 reaches the preset volume. It should be noted that when the intermittent blocking assembly 45 completes the blocking of the liquid inlet pipe 42, the left side of the separating plate 441 is misaligned with the lumen of the liquid outlet pipe 43, enabling the refrigerant to enter the condenser 3 through the liquid outlet pipe 43.

[0072] Furthermore, as Figure 3 shown in Figure 3 , the intermittent blocking assembly 45 includes:

[0073] The movable cavity 451 is opened on the quantitative guide tube 41, and the movable cavity 451 connects the inner cavity of the liquid inlet tube 42 and the inner cavity of the quantitative guide tube 41; the sealing plate 452 is movably arranged in the movable cavity 451; the elastic rod 455 is movably arranged in the movable cavity 451, and one end of the elastic rod 455 located in the movable cavity 451 (which can be understood as the left end) is interconnected with the sealing plate 452; the contact plate 453 is movably arranged in the quantitative guide tube 41, and the contact plate 453 is connected to one end of the elastic rod 455 located in the quantitative guide tube 41 (which can be understood as the right end).

[0074] The structural design of the intermittent blocking assembly 45 in this embodiment is simple and reasonable, and can be linked with the movement of the partition plate 441 without the need for an additional power source. This can not only ensure the high efficiency performance of the equipment, but also reduce the production cost of the equipment. During operation, as the partition plate 441 moves to the right, it will conflict with the contact plate 453, and the contact plate 453 will be moved to the right by the conflict. The rightward movement of the contact plate 453 will push the blocking plate 452 to the left through the elastic rod 455. The leftward movement of the blocking plate 452 will enter the liquid inlet pipe 42 and complete the blocking of the lumen of the liquid inlet pipe 42, preventing the refrigerant from continuing to be injected into the quantitative guide pipe 41, thereby achieving a quantitative effect. It should be noted that the blocking process is completed when the left end of the blocking plate 452 conflicts with the left side wall of the lumen of the liquid inlet pipe 42.

[0075] In order to ensure that the movement of the contact plate 453 is always in a horizontal state and the contact plate 453 can be reset to the initial position when the contact force is lost, the present invention also proposes the following example: Figure 3 As shown, the intermittent plugging component 45 also includes:

[0076] One end of the first telescopic component 454 (which can be understood as the left end) is fixedly connected to the side wall of the contact plate 453, and the other end of the first telescopic component 454 (which can be understood as the right end) is fixedly connected to the outer wall of the condenser 3. The first telescopic component 454 in the present invention is reasonably simple in design, which can not only ensure the linkage performance of the equipment, but also realize the guiding and limiting effect on the contact plate 453, so that the contact plate 453 only moves in the horizontal direction. At the same time, when the contact plate 453 loses its resistance force, it can also provide a reset force for the reset process of the contact plate 453.

[0077] Specifically, the first telescopic assembly 454 includes: a first telescopic rod 4541 fixedly arranged on the side wall of the contact plate 453; a first telescopic cylinder 4542 fixedly arranged on the outer side wall of the condenser 3, and the first telescopic cylinder 4542 is movably sleeved outside the first telescopic rod 4541; a first telescopic spring 4543 wound outside the first telescopic rod 4541, and two ends of the first telescopic spring 4543 are respectively fixedly connected to the side wall of the first telescopic rod 4541 and the outer side wall of the first telescopic cylinder 4542.

[0078] Preferably, the barrel cavities of the first telescopic rod 4541 and the first telescopic cylinder 4542 are both arranged as polygonal three-dimensional columnar structures, and such an arrangement can play a better limiting and guiding role. During operation, since the barrel cavities of the first telescopic rod 4541 and the first telescopic cylinder 4542 are both arranged as polygonal three-dimensional columnar structures, the movement of the first telescopic rod 4541 inside the first telescopic cylinder 4542 can limit the contact plate 453 to move only left or right in the horizontal direction. Due to the existence of the first telescopic spring 4543, it can play a resetting role. Specifically, when the first telescopic rod 4541 moves into or out of the first telescopic cylinder 4542, the first telescopic spring 4543 will be compressed or stretched. In this way, when the compression or stretching force is lost, under the action of the first telescopic spring 4543, the contact plate 453 will perform a resetting movement.

[0079] In order to enable all the refrigerant of a preset volume to enter the condenser 3 and make the equipment have a more accurate quantitative effect, in one embodiment, as Figure 4 shown, the cryogenic air source heat pump with quantitative diversion further includes a blowing mechanism 5 arranged on the partition plate 441, and the blowing mechanism 5 pressurizes the quantitative diversion pipe 41 to push all the refrigerant of the preset volume stored in the quantitative diversion pipe 41 into the condenser 3.

[0080] Specifically, the blowing mechanism 5 includes: a blower 51 arranged on the partition plate 441, and a plurality of air blowing holes 52 are formed on the partition plate 441, and the air blowing holes 52 are connected to the air outlet of the blower 51; a push-button switch 53 arranged on the side wall of the partition plate 441, and the push-button switch 53 is arranged on the side of the partition plate 441 close to the liquid outlet pipe 43.

[0081] The blowing mechanism 5 of the present invention has a rational structural design and can be linked with the movement of the partition plate 441. During operation, as the intermittent blocking assembly 45 completes the blocking of the liquid inlet pipe 42, the push-type switch 53 is triggered by contacting the outer wall of the condenser 3. The activation of the push-type switch 53 energizes the blower 51 and starts operating. The blower 51 blows air into the quantitative flow guide pipe 41 through the blowing hole 52, thereby pushing all the refrigerant in the quantitative flow guide pipe 41 into the condenser 3.

[0082] It is worth noting that when the blower 51 is working, a thrust to the right will be generated. In this way, even if the amount of refrigerant in the quantitative guide tube 41 is reduced, under the action of the gas thrust, the current state of the partition plate 441 will not change, that is, the sealing state of the intermittent sealing component 45, the state in which the liquid outlet pipe 43 is connected to the tube cavity of the quantitative guide tube 41 on the left side of the partition plate 441, and the power-on state of the blower 51 remain unchanged.

[0083] After all the refrigerant in the metered flow guide tube 41 has entered the condenser 3, the blower 51 is powered off. At this point, the partition plate 441 loses its rightward thrust. Then, under the action of the moving rod 442, moving cylinder 443, moving spring 444, and first telescopic assembly 454, the device returns to its initial position, preparing for the next refrigerant injection into the condenser 3.

[0084] In order to prevent the refrigerant entering the condenser 3 from flowing back, in one embodiment, Figure 5 As shown, the ultra-low temperature air heat pump with quantitative flow guidance further includes a backflow prevention mechanism 6 , which is used to prevent the refrigerant in the condenser 3 from flowing back into the quantitative flow guidance pipe 41 .

[0085] Specifically, the anti-backflow mechanism 6 includes:

[0086] A non-return tube 61 is provided at the liquid inlet of the liquid outlet pipe 43, and a trumpet-shaped tube cavity 62 is present in the non-return tube 61; a sealing plug 63 is provided in the trumpet-shaped tube cavity 62, and the sealing plug 63 is arranged to be in contact with the cavity wall of the trumpet-shaped tube cavity 62, and the sealing plug 63 has a cap-shaped structure; one end of the second telescopic component 64 (which can be understood as the upper end) is fixedly connected to the sealing plug 63, and the other end of the second telescopic component 64 (which can be understood as the lower end) is fixedly connected to the liquid outlet pipe 43, and the second telescopic component 64 is used to guide and support the movement of the sealing plug 63, and provide a reset force for the reset movement of the sealing plug 63.

[0087] Further, the second telescopic component 64 includes: a second telescopic rod 641 fixedly disposed on the lower end surface of the plugging block 63; a second telescopic cylinder 642 fixedly disposed on the liquid outlet pipe 43, and the second telescopic cylinder 642 is movably sleeved outside the second telescopic rod 641; a second telescopic spring 643 wound around the second telescopic rod 641, and two ends of the second telescopic spring 643 are respectively fixedly connected to the side wall of the second telescopic rod 641 and the outer side wall of the second telescopic cylinder 642.

[0088] In order to enable the refrigerant to work properly at ultra-low temperatures, in one embodiment, as Figure 6 and Figure 7 shown, the ultra-low temperature air source heat pump with quantitative diversion further includes a refrigerant temperature control mechanism 7 disposed on the liquid outlet pipe 43, and the refrigerant temperature control mechanism 7 is used to adjust the temperature of the passing refrigerant. The setting of this embodiment can preheat or precool the refrigerant to ensure the normal operation of the system in an ultra-low temperature environment.

[0089] Specifically, the refrigerant temperature control mechanism 7 includes: a temperature control box 71 fixedly sleeved outside the liquid outlet pipe 43; a temperature adjustment pipe 74 disposed in the temperature control box 71, and the temperature adjustment pipe 74 is used for connecting with the liquid outlet pipe 43; a refrigerator 72 fixedly disposed on the outer side wall of the temperature control box 71; a heater 73 fixedly disposed on the outer side wall of the temperature control box 71; a first heat transfer rod 75 fixedly inserted on the temperature control box 71, and the first heat transfer rod 75 is used for connecting the heater 73 and the temperature adjustment pipe 74, and the first heat transfer rod 75 plays a role in heat transfer; a second heat transfer rod 76 fixedly inserted on the temperature control box 71, and the second heat transfer rod 76 is used for connecting the refrigerator 72 and the temperature adjustment pipe 74, and the second heat transfer rod 76 plays a role in heat transfer; a temperature sensor 77 disposed on the inner side wall of the temperature adjustment pipe 74 for real-time temperature monitoring of the refrigerant in the temperature adjustment pipe 74.

[0090] It should be noted that the temperature adjustment pipe 74 is made of a heat-conducting material; the start of the refrigerator 72 and the heater 73 can respectively transfer heat to the temperature adjustment pipe 74 through the second heat transfer rod 76 and the first heat transfer rod 75.

[0091] In this embodiment, the structural design of the refrigerant temperature control mechanism 7 is reasonable, and it can preheat or precool the refrigerant. Moreover, a temperature sensor 77 is provided in the present invention, which can sense the temperature of the refrigerant in real time, so that the temperature of the refrigerant always remains at a constant temperature.

[0092] Further, as Figure 7As shown, the temperature control pipe 74 includes: a horizontal section, and there are two of the horizontal sections; a vertical section disposed between the two horizontal sections, and the number of the vertical sections is set to be several; an arc section disposed between the two horizontal sections, and the number of the arc sections is set to be several; wherein, the several vertical sections and the several arc sections are alternately connected, and two of the vertical sections are respectively connected to the two horizontal sections.

[0093] In this embodiment, the structural design of the temperature control pipe 74 is reasonable. Through the arrangement of two horizontal sections, several vertical sections and several arc sections, the movement path of the refrigerant in the temperature control pipe 74 can be effectively extended, so that the temperature regulation time of the refrigerant can be increased, and thus the temperature of the refrigerant coming out of the temperature control pipe 74 is more constant.

[0094] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and can be implemented or realized in various ways.
