Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0053] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0054] See also Figure 1-4An embodiment of the present invention provides a heat exchanger 1, which is applied to an air conditioner 2. The air conditioner 2 includes a compressor 21 and a chassis 22. The heat exchanger 1 includes a compressor pipeline 11 with one end arranged on the exhaust side of the compressor 21 and a chassis pipeline 12 with one end arranged on a water storage tank 221 of the chassis 22. The heat exchanger 1 also includes a pipeline separation component 13. The pipeline separation component 13 includes a first separation component 131 and a second separation component 132 that can be separated and contacted. The other end of the compressor pipeline 11 is connected to the first separation component 131, and the other end of the chassis pipeline 12 is connected to the second separation component 132. When the first separation component 131 contacts the second separation component 132, heat exchange between the compressor pipeline 11 and the chassis pipeline 12 can be achieved.

[0055] In this embodiment, the heat exchanger 1 includes a compressor pipeline 11, a chassis pipeline 12 and a pipeline separation assembly 13. One end of the compressor pipeline 11 is connected to the compressor 21, and is used to lead out the high-temperature gas generated during the exhaust process of the compressor 21. One end of the chassis pipeline 12 is connected to the water storage tank 221 of the chassis 22. The water temperature in the water storage tank 221 is relatively low and is suitable for absorbing heat. The pipeline separation assembly 13 includes a first separation component 131 and a second separation component 132, which are respectively connected to the other end of the compressor pipeline 11 and the chassis pipeline 12. When the first separator 131 is separated from the second separator 132, only the compressor pipe 11 is used, that is, the exhaust side of the compressor 21 can only transfer heat to the first separator 131 through the compressor pipe 11, but cannot transfer it to the second separator 132; when the first separator 131 is in contact with the second separator 132, a heat exchange interface is formed between them, and the high-temperature gas in the compressor pipe 11 releases heat to the second separator 132 through the first separator 131, and the chassis pipe 12 absorbs this heat through the second separator 132, thereby realizing heat exchange between the compressor pipe 11 and the chassis pipe 12. This embodiment uses the compressor pipe 11 to lead out the heat generated during the compressor exhaust process, thereby reducing the exhaust side temperature and exhaust pressure of the compressor, and by controlling the contact between the first separator and the second separator, the heat of the compressor pipe 11 is transferred to the water storage tank 221 of the chassis 22 through the chassis pipe 12, so that the chassis can be prevented from accumulating water and freezing without consuming electrical energy.

[0056] In the specific implementation, the compressor pipeline 11 and the chassis pipeline 12 can be a round tube or a flat tube, the inside of which is evacuated, and can be set with or without a liquid wick, and then the heat transfer medium is poured inside; the compressor pipeline 11 and the chassis pipeline 12 can be made of copper tube, aluminum tube, iron tube or glass tube, and copper tube is preferred for better heat transfer; the compressor pipeline 11 and the chassis pipeline 12 can be set in a ring shape, a zigzag shape or a straight strip shape, which can be specifically referred to Figure 6 and Figure 7 , Figure 6 The compressor pipe 11 is arranged in an annular shape. Figure 7 The chassis pipeline 12 is configured as a broken line. The compressor pipeline 11 and the chassis pipeline 12 can be configured as required, and the number of the configured pipelines ranges from 1 to 10.

[0057] In addition, the compressor pipeline 11 itself is a circulation pipeline, and the chassis pipeline 12 itself is also a circulation pipeline. The compressor pipeline 11 and the chassis pipeline 12 both include an evaporation section and a condensation section. The condensation section of the compressor pipeline 11 is connected to the first separation element 131, and the evaporation section of the compressor pipeline 11 is arranged inside the compressor. The condensation section of the chassis pipeline 12 is arranged in the water storage tank 221, and the evaporation section of the chassis pipeline 12 is connected to the second separation element 132. Figure 6 The annular part in the middle is the evaporation section of the compressor pipe 11. Figure 6 The middle straight strip portion is the condensation section of the compressor pipeline 11, and a heat preservation member is arranged at a part of the condensation section of the compressor pipeline 11 to prevent heat dissipation. Figure 7 The straight strip portion parallel to the ground is the condensation section of the chassis pipe 12. Figure 7 The straight strip portion perpendicular to the ground is the evaporation section of the chassis pipe 12, and a heat preservation member is arranged at a part of the evaporation section of the chassis pipe 12 to prevent heat dissipation.

[0058] Specifically, Figure 5 As shown, the pipeline separation assembly 13 further includes a driving member 133 , and the driving member 133 is used to drive the first separation member 131 and the second separation member 132 to separate and contact.

[0059] In this embodiment, by setting up a driving member 133, the automatic operation of the pipeline separation component 13 can be realized. The driving member 133 can quickly and accurately drive the first separation component 131 and the second separation component 132 to separate or contact, which makes the pipeline separation component 13 have higher flexibility and adaptability when facing different working conditions.

[0060] Specifically, Figure 5 As shown, the driving member 133 includes a first electromagnetic member 1331 and a second electromagnetic member 1332. The first electromagnetic member 1331 is arranged in the first separation member 131, and the second electromagnetic member 1332 is arranged in the second separation member 132. The first electromagnetic member 1331 and / or the second electromagnetic member 1332 form an attractive or repulsive magnetic field force according to the direction of the input current to make the first separation member 131 and the second separation member 132 approach or move away from each other.

[0061] In this embodiment, by respectively arranging electromagnetic components in the two separation components, when the direction of the current input to one of the electromagnetic components changes, the direction of the magnetic field generated between the first electromagnetic component 1331 and the second electromagnetic component 1332 will also change, so that the magnetic fields between the two electromagnetic components attract or repel each other. The magnetic field force of attraction or repulsion will act on the first separation component 131 and the second separation component 132, so that the two separation components are closer or farther away. This driving method realizes the separation and contact of the first separation component 131 and the second separation component 132 through the magnetic field force, avoiding the direct contact and friction in the traditional mechanical driving method, and helping to ensure the stability and reliability of the pipeline separation component during the separation and contact process.

[0062] Specifically, Figure 5 As shown, one of the first separating member 131 and the second separating member 132 is provided with a guide hole 1311 , and the other of the first separating member 131 and the second separating member 132 is provided with a guide rod 1321 , and the guide rod 1321 is slidably connected in the guide hole 1311 .

[0063] In this embodiment, in order to make the first separation member 131 and the second separation member 132 separate and contact more smoothly, a guide hole 1311 is provided in one of the first separation member 131 and the second separation member 132, and a guide rod 1321 is provided in the other of the first separation member 131 and the second separation member 132. The guide rod 1321 is inserted into the guide hole 1311, and a limiting member, such as a positioning convex ring or a nut, is provided on the top of the guide rod 1321, so as to realize the connection between the two separation members and limit the maximum distance that the two separation members can be separated. When the two separation members are separated or contacted, they can slide along the guide rod 1321, so as to control the precise separation or contact of the two separation members and avoid misalignment or excessive separation. In the specific implementation, refer to Figure 4 and 5 As shown, a plurality of guide holes 1311 are provided on the first separating member 131, and the same number of guide rods 1321 are provided at corresponding positions of the second separating member 132 toward the first separating member 131. When the guide rods 1321 are inserted into the guide holes 1311, the length of the guide rods 1321 is greater than the depth of the guide holes 1311, and the guide rods 1321 protrude a predetermined distance from the guide holes 1311. A limiting member is provided at one end of the protrusion, and the separation or contact of the two separating members can be achieved by sliding a predetermined distance.

[0064] In a specific implementation, the number of guide rods 1321 and guide holes 1311 can be set according to the specific scenario. If a single guide rod 1321 and a single guide hole 1311 are set, they can be set in the central area of ​​the first separating member 131 and the second separating member 132. If multiple guide rods 1321 and multiple guide holes 1311 are set, they can be set in the surrounding areas of the first separating member 131 and the second separating member 132, so that the sliding process is more stable.

[0065] Specifically, Figure 5 As shown, the first separation component 131 includes a first heat exchange component 1312 and a first thermal insulation component 1313 covering the first heat exchange component 1312, and the second separation component 132 includes a second heat exchange component 1322 and a second thermal insulation component 1323 covering the second heat exchange component 1322. Both the first heat exchange component 1312 and the second heat exchange component 1322 are made of heat conductive materials.

[0066] In this embodiment, the heat in the compressor pipeline 11 is transferred through the first heat exchanger 1312 and the second heat exchanger 1322. Therefore, the first heat exchanger 1312 and the second heat exchanger 1322 are preferably configured as heat-conducting materials to better transfer heat. Moreover, in order to ensure that the heat is transferred to the maximum extent, a first heat-insulating member 1313 is arranged on the outside of the first heat exchanger 1312, and a second heat-insulating member 1323 is arranged on the outside of the second heat exchanger 1322. When it is necessary to transfer heat to the water storage tank 221 of the chassis 22, the two electromagnetic members are input with corresponding currents to generate a magnetic force of mutual attraction to achieve contact between the two heat exchangers. The contacting side of the two heat exchangers is a smooth plane. Under the action of the magnetic force, the thermal resistance is very small when in close contact. Moreover, the first heat-insulating member 1313 and the second heat-insulating member 1323 are both unsealed box-shaped structures. The two heat exchangers are embedded in the box-mounted structure, and the two heat exchangers achieve heat exchange through the unsealed side. The insulation materials of the first insulation member 1313 and the second insulation member 1323 may be foamed rubber or foam with a thickness of 3-20 mm, thereby effectively preventing heat loss during the transfer process.

[0067] like Figure 1-3 As shown, an embodiment of the present invention further provides an air conditioner 2, including a compressor 21 and a chassis 22, and also including the heat exchanger 1 as described above.

[0068] In this embodiment, by setting up a heat exchanger 1, the heat generated by the compressor 21 during the exhaust process can be drawn out and directed to the chassis 22, thereby preventing the accumulated water in the water tank 221 in the chassis 22 from freezing. In this way, not only can the exhaust pressure of the compressor 21 be reduced, but it is also beneficial to discharge the accumulated water in the water tank 221.

[0069] Specifically, Figure 2-3 As shown, an electric heating component 23 is provided on the bottom plate 22 for heating the accumulated water in the water storage tank 221 .

[0070] In this embodiment, in order to prevent the temperature inside the air conditioner from dropping when the compressor 21 stops or the air conditioner is in low-temperature cooling mode, causing the accumulated water in the water tank 221 in the chassis 22 to freeze, an electric heating component 23 is additionally provided on the chassis 22. When the heat on the exhaust side of the compressor is insufficient and the heat exchanger 1 still cannot melt the accumulated water in the water tank 221 after heat exchange, the electric heating component 23 can be directly turned on to heat the accumulated water in the water tank 221, thereby effectively avoiding the problem of accumulated water freezing.

[0071] Specifically, a temperature sensor is also provided on the chassis 22 for detecting the water temperature of the water storage tank 221 .

[0072] In this embodiment, in order to prevent the water temperature in the water tank 221 from being too low and causing the accumulated water to freeze, it is necessary to always pay attention to the water temperature in the water tank 221 so as to timely increase the water temperature through the electric heating component 23 or the heat exchanger 1. Therefore, a temperature sensor is provided on the chassis 22, preferably in the water tank 221, and the water temperature of the water tank 221 is detected in real time by the temperature sensor. If the water temperature of the water tank 221 drops to a predetermined value, the heat exchanger 1 or the electric heating component 23 is directly turned on. The predetermined value can be set according to the specific implementation scenario.

[0073] like Figure 8 As shown, the embodiment of the present invention also provides a method for controlling an air conditioner, comprising steps S10-S20:

[0074] S10, when receiving a cooling mode instruction, obtaining the outdoor temperature, and controlling the separation or contact of the first separation element 131 and the second separation element 132 according to the outdoor temperature;

[0075] S20 , when a heating mode instruction is received, controlling the first separation member 131 and the second separation member 132 to contact each other.

[0076] In this step, the air conditioner includes two operating modes, namely, cooling mode and heating mode. In different operating modes, the working state of the first separator 131 and the second separator 132 is different. This is because when the first separator 131 and the second separator 132 are in contact, the heat of the compressor 21 can be drawn out and the water in the water storage tank 221 can be heated. The heat transfer process is as follows: the heat on the exhaust side of the compressor 21 is transferred to the first separator 131 through the compressor pipeline 11, the first separator 131 is transferred to the second separator 132 through the contact side, and the second separator 132 is transferred to the water storage tank 221 through the chassis pipeline 12; when the first separator 131 and the second separator 132 are in contact, the heat of the compressor 21 can be drawn out, so as to reduce the exhaust temperature of the compressor and the exhaust pressure. Therefore, it is necessary to judge whether the air conditioner needs to draw the heat of the compressor 21 to the water storage tank 221 in the current operating mode. If necessary, the two separators are driven to contact through the driving member 133, and if not, the two separators are driven to separate through the driving member 133.

[0077] In one embodiment, if Fig. 9 As shown, S10 includes:

[0078] S11, determining whether the outdoor temperature is greater than a first temperature threshold;

[0079] S12, if the outdoor temperature is greater than a first temperature threshold, controlling the first separation element 131 and the second separation element 132 to contact;

[0080] S13: If the outdoor temperature is less than or equal to a first temperature threshold, control the first separation element 131 and the second separation element 132 to separate.

[0081] In this embodiment, in the cooling mode, it is also necessary to make a judgment based on the outdoor temperature in order to more accurately control the separation and contact of the first separation element 131 and the second separation element 132. In a specific implementation, the first temperature threshold is the separation temperature value of the first separation element 131 and the second separation element 132, which is usually set to 35-50°C.

[0082] When the outdoor temperature is less than or equal to the first temperature threshold, the refrigeration load is not high. If the water in the water tank 221 is heated, the effect of the condenser using the accumulated water in the water tank for water cooling and heat exchange will be reduced. Therefore, at this stage, there is no need to direct the heat of the compressor 21 to the water tank 221, and the first separator 131 and the second separator 132 need to be separated. At this time, currents in opposite directions are input to the first electromagnetic component 1331 and the second electromagnetic component 1332, so that the first electromagnetic component 1331 and the second electromagnetic component 1332 generate mutually repulsive magnetic forces, thereby separating the first separator 131 and the second separator 132 through the mutually repulsive electromagnetic forces, and the separation gap reaches any value in the range of 5-50mm. At this time, the first separator 131 cannot transfer heat to the second separator 132, thereby blocking the exhaust side of the compressor 21 from releasing heat to the water tank 221.

[0083] When the outdoor temperature is greater than the first temperature threshold, the cooling load is very high, the exhaust temperature of the compressor 21 increases, and the compressor 21 is easily overloaded and shut down. At this time, the exhaust temperature of the compressor 21 needs to be reduced, that is, the first separator 131 and the second separator 132 are in contact. At this time, the first electromagnetic member 1331 and the second electromagnetic member 1332 are input with the same direction current, so that the first electromagnetic member 1331 and the second electromagnetic member 1332 generate a magnetic force that attracts each other, and the first separator 131 and the second separator 132 are tightly attracted together, so as to achieve contact. At this time, the heat of the compressor pipeline 11 is transferred to the second separator 132 through the first separator 131, thereby heating the chassis pipeline 12, and transferring the heat to the water storage tank 221. It should be noted that in this environment, the water storage tank 221 may not have accumulated water, but there is wind passing through the chassis 22. Therefore, after the heat of the exhaust part of the compressor 21 is transferred to the chassis pipeline 12 through a series of components, the chassis pipeline 12 dissipates heat through air cooling, thereby reducing the exhaust temperature of the compressor 21.

[0084] When the air conditioner cannot dissipate heat, it will not work after the exhaust temperature of the compressor 21 reaches above 54°C. Therefore, using an air conditioner with air cooling, the outdoor ambient temperature for normal refrigeration operation can be increased to about 60°C, thereby improving the high temperature resistance of the compressor 21, avoiding shutdown due to excessive exhaust temperature, and achieving the purpose of increased refrigeration.

[0085] In one embodiment, if Fig.10 As shown, S20 includes:

[0086] S21, obtaining the drainage mode of the air conditioner 2; wherein the drainage mode of the air conditioner includes a non-external drainage mode and an external drainage mode;

[0087] S22, if the drainage mode of the air conditioner 2 is the non-external drainage mode, obtaining the water temperature of the water storage tank 221, and controlling the on and off of the electric heating component 23 according to the water temperature;

[0088] S23. If the drainage mode of the air conditioner 2 is the external drainage mode, the outdoor temperature and the duration of the compressor 21 in the current operating state are obtained, and the turning on and off of the electric heating component 23 is controlled according to the outdoor temperature and the duration.

[0089] In this embodiment, in the heating mode, it is also necessary to obtain the drainage mode of the air conditioner 2, and determine whether to turn on the electric heating component 23 according to the drainage mode and the corresponding start-up conditions to heat the accumulated water in the water storage tank 221.

[0090] In one embodiment, if Fig.11 As shown, S22 includes:

[0091] S221, if the water temperature is less than or equal to a second temperature threshold, start the electric heating component 23;

[0092] S222: If the water temperature is greater than or equal to a third temperature threshold, turning off the electric heating component 23; wherein the third temperature threshold is greater than the second temperature threshold;

[0093] S223: If the water temperature is greater than the second temperature threshold and less than the third temperature threshold, the current state of the electric heating component 23 is maintained.

[0094] This embodiment shows the on and off conditions of the electric heating component 23 when the drainage mode is a non-external drainage mode, wherein the second temperature threshold is the on temperature of the electric heating component 23, and the third temperature threshold is the off temperature of the electric heating component 23. The on temperature and the off temperature of the electric heating component 23 can be set in advance, and the on temperature of the electric heating component 23 can be set to 0-10°C, and the off temperature of the electric heating component 23 can be set to 2-15°C. When the drainage mode of the air conditioner 2 is the non-external drainage mode (i.e., it cannot be discharged outdoors), there is water accumulation in the water storage tank 221 for a long time. By detecting the water temperature of the accumulated water and judging the magnitude of the current water temperature of the accumulated water and the second temperature threshold and the third temperature threshold, if the water temperature is less than or equal to the second temperature threshold, the electric heating component 23 is turned on and the electric heating component 23 is powered on. At this time, the electric heating component 23 works to generate heat and raises the water temperature of the water storage tank 221 together with the heat exchanger 1, so that the water temperature of the water storage tank 221 is above 0°C to prevent the accumulated water from freezing; when it is detected that the water temperature is greater than or equal to the third temperature threshold, the electric heating component 23 is turned off and the electric heating component 23 is powered off. At this time, the water temperature of the water storage tank 221 is maintained only by the heat exchanger 1 to save electricity. When the water temperature is greater than the second temperature threshold and less than the third temperature threshold, the current state of the electric heating component 23 is maintained, that is, the electric heating component 23 is powered on if it was powered on before, and is powered off if it was powered off before. In this embodiment, the electric heating assembly 23 is turned on in real time to achieve continuous and uninterrupted heat supply to the chassis 22, while maximizing the energy-saving effect of chassis ice-melting.

[0095] In one embodiment, if Fig.12 As shown, S23 includes:

[0096] S231, if the outdoor temperature is greater than or equal to a fourth temperature threshold, turning off the electric heating component 23;

[0097] S232: If the outdoor temperature is less than or equal to a fifth temperature threshold, start the electric heating component 23; wherein the fourth temperature threshold is greater than the fifth temperature threshold;

[0098] S233: If the outdoor temperature is greater than the fifth temperature threshold and less than the fourth temperature threshold, obtain the duration and determine whether the duration is greater than the time threshold;

[0099] S234, if the duration is greater than the time threshold, start the electric heating component 23;

[0100] S235: If the duration is less than or equal to the time threshold, turn off the electric heating component 23.

[0101] This embodiment shows the on and off conditions of the electric heating component 23 when the drainage mode is the external drainage mode, wherein the fourth temperature threshold value can be any value between 0 and 10°C, the fifth temperature threshold value is the off temperature of the electric heating component 23, the time threshold value is the upper limit of the compressor downtime, the off temperature of the electric heating component 23 and the upper limit of the compressor downtime can be set in advance, the off temperature of the electric heating component 23 can be set to any value between -15 and -1°C, and the upper limit of the compressor downtime can be set to any value between 15 and 120 minutes.

[0102] When the drainage mode of the air conditioner 2 is the external drainage mode (i.e., it can be discharged outdoors), there may not be much water in the water storage tank 221. At this time, the temperature sensor cannot effectively detect the water temperature, and the switch of the electric heating component 23 can be controlled by the outdoor temperature and the operating state of the compressor; when the outdoor temperature is greater than or equal to the fourth temperature threshold, the electric heating component 23 is directly turned off; when the outdoor temperature is less than or equal to the fifth temperature threshold, the electric heating component 23 is started to work with the heat exchanger 1 to increase the water temperature of the water storage tank 221, so that the temperature of the accumulated water is maintained above 0°C to prevent the accumulated water from freezing; when the outdoor temperature is greater than the fifth temperature threshold and less than the fourth temperature threshold, the current operating state of the compressor is obtained, if the current operating state of the compressor is running, the duration of the operation is obtained, if the current operating state of the compressor is shutdown, the duration of the shutdown is obtained, and then the duration in the current operating state is judged with the time threshold, if the duration is greater than the time threshold, the electric heating component 23 is turned on until the compressor 21 runs again and then shuts down, if the duration is less than or equal to the time threshold, the electric heating component 23 is turned off.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
