Detailed Embodiment

[0032] The following description and drawings fully illustrate the specific embodiments herein, enabling those skilled in the art to practice them. Parts and features of some embodiments may be included in or replace parts and features of other embodiments. The scope of the embodiments herein includes the entire scope of the claims and all available equivalents of the claims.

[0033] As Figure 1 shown, an embodiment of the present disclosure provides a fluid pipeline, including a pipe body 100 and an electromagnetic heating device; wherein, the electromagnetic heating device includes an alternating body part 310, and the alternating body part 310 is configured to generate an alternating magnetic field when an alternating current is passed through; the pipe body 100 is placed in the alternating magnetic field and is configured to generate an induced electromotive force under the action of the alternating magnetic field.

[0034] Optionally, the alternating body part 310 can be arranged near the side of the pipe body 100, such that the pipe body 100 is placed in the alternating magnetic field generated by the alternating body part 310. It can also be placed in other positions, as long as the pipe body 100 is placed in the alternating magnetic field generated by the alternating body part 310, and this embodiment does not limit this.

[0035] Adopting this embodiment, when the pipe body 100 forms a conductive loop with an external pipeline, such as the heating loop of an air conditioner, an induced current will be generated in the pipe body 100 under the action of the induced electromotive force. The direction of this induced current is opposite to the direction of the driving current (i.e., the input current of the alternating body part 310) in the electromagnetic heating device. Therefore, Joule heat is generated in the pipe body 100, and the pipe body 100 then transfers the Joule heat to the flowing medium inside the pipe body 100, thereby realizing the heating of the flowing medium, such as refrigerant, effectively improving the specific volume of the refrigerant in the heating loop, and further improving the low - temperature heating capacity of the air conditioner and the heating effect.

[0036] Optionally, the pipe body 100 is made of a conductor material and can generate an induced electromotive force under the action of an alternating magnetic field. When the pipe body 100 is connected to the heating loop of an air conditioner, the pipe body 100 and the heating loop form a conductive loop, and this conductive loop can generate an induced current under the action of the induced electromotive force.

[0037] Optionally, the pipe body 100 is a martensitic steel pipe.

[0038] Optionally, a conductive path is provided on the pipe body 100. When the pipe body 100 is connected to the heating circuit of the air conditioner, the pipe body 100 and the heating circuit form a conductive loop through the conductive path, and an induced current can be generated in the conductive loop under the action of the induced electromotive force.

[0039] Optionally, the electromagnetic heating device further includes a magnetic body part 320 that can surround the pipe body 100, and is arranged to concentrate the alternating magnetic field on the magnetic body part 320.

[0040] With this embodiment, since the magnetic body part 320 is arranged to surround the pipe body 100, when the alternating magnetic field is concentrated on the magnetic body part 320, the alternating magnetic field will also surround the pipe body 100, thereby enhancing the electromagnetic field around the pipe body 100 to enhance the induced electromotive force. When the pipe body 100 forms a conductive loop with an external pipeline, such as the heating circuit of the air conditioner, the enhanced induced electromotive force will cause an increase in the induced current, thereby generating more Joule heat, improving the refrigerant heating effect, effectively increasing the specific volume of the refrigerant in the heating circuit, further enhancing the low-temperature heating capacity of the air conditioner, and improving the heating effect.

[0041] Optionally, the alternating body part 310 is arranged on the magnetic body part 320.

[0042] Optionally, the alternating body part 310 is an induction coil wound around the magnetic body part 320. When an alternating current is passed into the induction coil, the magnetic body part 320 generates an alternating magnetic field.

[0043] Optionally, the magnetic body part 320 is of a closed structure or an open structure.

[0044] Compared with the magnetic body part 320 of the open structure, the magnetic body part 320 of the closed structure further concentrates the alternating magnetic field on the magnetic body part 320 to further enhance the induced electromotive force and the induced current, ultimately improving the refrigerant heating effect, effectively increasing the specific volume of the refrigerant in the heating circuit, further enhancing the low-temperature heating capacity of the air conditioner, and improving the heating effect.

[0045] Optionally, the magnetic body part 320 is rectangular or annular.

[0046] Optionally, the alternating body part 310 is wound around one rectangular side of the rectangular magnetic body part; the alternating magnetic field is concentrated inside the magnetic body part 320.

[0047] Optionally, a magnetic isolation layer is provided on the alternating body part 310.

[0048] Optionally, the magnetic isolation layer is arranged on the outer surface of the alternating body part 310.

[0049] With this embodiment, the alternating body part 310 avoids electromagnetic interference through the magnetic isolation layer.

[0050] Optionally, a heat insulation layer is provided on the pipeline body 100.

[0051] Optionally, the heat insulation layer is coated on the outer surface of the pipeline body 100.

[0052] With this embodiment, the alternating magnetic field directly heats the pipeline body 100 through the heat insulation layer, with very high thermal efficiency and almost no loss of heat energy. Moreover, since the pipeline body 100 generates heat by itself under the action of the alternating magnetic field, there is also no loss of heat transfer. The overall energy saving is about 30%-70% of resistance heating under the same conditions.

[0053] Optionally, an anti-magnetic leakage layer is provided on the magnetic body part 320.

[0054] Optionally, the anti-magnetic leakage layer is an anti-magnetic leakage paper coated on the outside of the magnetic body part 320, or an anti-magnetic leakage coating layer coated on the outside of the magnetic body part 320.

[0055] With this embodiment, the amount of magnetic leakage is reduced through the anti-magnetic leakage layer to ensure the electromagnetic induction heating effect.

[0056] As Figure 4 shown, this embodiment of the present disclosure also discloses a fluid pipeline, including:

[0057] A pipeline body 100;

[0058] A first flow disturbing member 210, which is configured to partially disturb the fluid in the pipeline body 100 and form a fluid flow;

[0059] A second flow disturbing member 220, which is configured to disturb the fluid flow formed by the first flow disturbing member 210.

[0060] In this article, the fluid flow refers to the fluid in a flowing state.

[0061] Optionally, the fluid flow is that the fluid flows in a straight line. For example, as Figure 8 shown, the first flow disturbing member 210 is a convex rib 211 extending along the circumferential direction of the inner wall of the pipeline body 100. A first channel 101 is formed in the center of the convex rib 211. In this way, the fluid flows in a straight line in the first channel 101. For example, the first flow disturbing member includes an annular baffle, and a channel is formed in the center of the annular baffle. In this way, the fluid flows in a straight line in the channel.

[0062] Optionally, the fluid flow is in a curved path. For example, the first spoiler 210 includes a baffle, and there are multiple first spoilers 210 which are arranged offset in the length direction of the pipe body. In this way, the formed fluid flow is in a curved path. For example, the first spoiler 210 includes a block with an outer diameter equal to the inner diameter of the pipe body, and the block has a curved channel penetrating the block in the length direction of the pipe body 100. In this way, the formed fluid flow is in a curved path.

[0063] In this embodiment, by arranging the first spoiler 210 and the second spoiler 220 in the pipe body 100, when the fluid in the pipe body 100 passes through the first spoiler 210, part of the fluid is disturbed, and then a fluid flow is formed. The fluid flow is further disturbed by the second spoiler 220, so that the positions of the various parts of the fluid can be changed, which is beneficial to the various parts of the fluid approaching the inner wall of the pipe body 100.

[0064] Optionally, the first spoiler 210 disturbs the fluid close to the inner wall of the pipe body 100.

[0065] Optionally, the first spoiler 210 disturbs the fluid close to the central axis of the pipe body 100. In this way, the disturbance of part of the fluid can be realized.

[0066] Optionally, the second spoiler 220 is arranged in the space through which the fluid flow formed by the first spoiler 210 passes. In this way, the fluid flow formed by the first spoiler 210 can be disturbed.

[0067] Optionally, the fluid flow formed by the first spoiler 210 passes through the central axis of the pipe body 100, or passes through the part between the central axis and the inner wall of the pipe body 100. In this way, the fluid close to the inner wall of the pipe body 100 is disturbed, and the fluid passes through the central axis part of the pipe body 100. For example, as Figure 8 shown, the first spoiler 210 is a convex rib 211 extending along the circumferential direction of the inner wall of the pipe body 100. A first channel 101 is formed at the center of the convex rib 211. In this way, the fluid passes through the central axis part of the pipe body 100. For another example, the first spoiler 210 includes a block with an outer diameter equal to the inner diameter of the pipe body 100, and the block has a channel penetrating the block in the length direction of the pipe body 100, and this channel is located at the part between the central axis of the pipe body 100 and the inner wall of the pipe body 100.

[0068] Optionally, the first spoiler 210 is perpendicular to the inner wall of the pipe body 100.

[0069] Optionally, the first spoiler 210 is inclined relative to the inner wall of the pipe body 100. In this way, the fluid can be disturbed.

[0070] Optionally, the first spoiler 210 is inclined relative to the longitudinal direction of the pipe body 100, or inclined relative to the direction perpendicular to the longitudinal direction of the pipe body 100. For example, the first spoiler 210 is plate-shaped and can be inclined relative to the longitudinal direction of the pipe body 100, or inclined relative to the direction perpendicular to the longitudinal direction of the pipe body 100, or can be perpendicular to the inner wall of the pipe body 100.

[0071] Optionally, the first spoiler 210 is inclined towards the flow direction of the fluid.

[0072] Optionally, the first spoiler 210 is inclined away from the flow direction of the fluid. In this way, it is beneficial to disturb the fluid.

[0073] Optionally, one or both ends of one or more of the first spoiler 210 and the second spoiler 220 are connected to the inner wall of the pipe body 100.

[0074] Optionally, as Figure 4 shown, the first spoilers 210 are arranged oppositely. Optionally, as Figure 4 shown, the first spoilers 210 are symmetrically arranged oppositely. Optionally, there are multiple second spoilers 220 and they are arranged oppositely. Optionally, there are multiple first spoilers 210 and they have different sizes. Optionally, there are multiple second spoilers 220 and they have different sizes. Optionally, there are multiple first spoilers 210 and multiple second spoilers 220, and one or more of the first spoilers 210 and the second spoilers 220 have the same or different sizes.

[0075] As Figures 4 to 6 shown, a fluid pipe includes:

[0076] A pipe body 100;

[0077] A first spoiler 210, arranged on the inner wall of the pipe body 100 and forming a first channel 101 for the fluid to pass through at the central axis part of the pipe body;

[0078] A second spoiler 220, arranged on the extension line of the first channel 101 along the longitudinal direction of the pipe body 100.

[0079] The first spoiler 210 forms a first channel 101 for the fluid to pass through at the central axis part of the pipe body 100. When the fluid flows through the first spoiler 210, the fluid near the inner wall of the pipe body 100 is disturbed, and the fluid converges at the central axis part of the pipe body 100 to form a through-flow, and the second spoiler 220 disturbs the formed through-flow.

[0080] During the actual working process, when the fluid passes through the first flow spoiler 210, the fluid converges to the central axis part of the pipe body; when the fluid passes through the second flow spoiler 220, the fluid diverges and approaches the position of the inner wall of the pipe body 100. During the process of confluence and divergence, the positions of the various parts of the fluid can be transformed, which is beneficial for the various parts of the fluid to approach the inner wall of the pipe body 100.

[0081] The fluid can be a liquid, a gas, or a gas-liquid mixture. For example, the fluid is a refrigerant. When the refrigerant passes through the fluid channel, the probability of each part of the refrigerant approaching the inner wall of the pipe body 100 is increased. In this way, it is beneficial for the refrigerant to absorb the heat outside the pipe body 100 or dissipate heat to the outside of the pipe body 100.

[0082] Optionally, the second flow spoiler 220 penetrates the pipe body 100 in the diameter direction and divides the inside of the pipe body 100 into two second channels 102. In this way, after the fluid is disturbed by the second flow spoiler, the fluid flows through the two second channels 102 respectively.

[0083] Optionally, the pipe body 100 is made of stainless steel. Optionally, the pipe body 100 is made of martensitic stainless steel. In this way, on the one hand, the pipe body 100 is prevented from being corroded by the internal fluid, and on the other hand, the heat exchange between the internal fluid of the pipe body 100 and the external environment of the pipe body 100 is enhanced.

[0084] Optionally, both the first flow spoiler 210 and the second flow spoiler 220 are made of stainless steel. Optionally, both the first flow spoiler 210 and the second flow spoiler 220 are made of martensitic stainless steel. In this way, the pipe body 100 is prevented from being corroded by the internal fluid.

[0085] Optionally, the width ratio of the first channel 101 to the second channel 102 is m, and 0.8 ≤ m ≤ 1.2. In this way, it is beneficial for the various parts of the fluid to approach the inner wall of the pipe body 100 during the flow process.

[0086] Optionally, the average width of the first channel 101 is a, the diameter of the column is d1, and the inner diameter of the pipe body 100 is d2, and 1 / 4d2 ≤ a ≤ 1 / 2d2; the average width of the second channel 102 is b, and 1 / 8d2 ≤ b ≤ 1 / 4d2. In this way, when the fluid flows through the first channel 101 and the second channel 102, it is beneficial for the various parts of the fluid to approach the inner side wall of the pipe body 100 during the flow process.

[0087] Figure 7 It is another schematic diagram of the internal structure of the pipe body provided by the embodiment of the present disclosure; Figure 8 is Figure 7 the A-A sectional view of Figure 9 is Figure 7 the B-B sectional view of. AsFigures 7 to 9 As shown, optionally, the first spoiler 210 includes a rib 211 formed by extending along the circumferential direction of the inner wall of the pipe body 100. The space surrounded by the rib 211 forms the first channel 101. In this way, the fluid can flow through the center of the fluid channel.

[0088] Optionally, the first spoiler 210 includes two baffles formed by extending towards each other from the inner walls of the pipe body 100 that are opposite in position. A first channel 101 is formed between the two baffles. In this way, the fluid flows through the first channel 101 between the two baffles in a concentrated manner.

[0089] Optionally, the baffle is bow-shaped, the arc edge of the baffle is connected to the inner wall of the pipe body 100, and the straight edges of the two baffles and the inner wall of the pipe body 100 enclose the first channel 101. In this way, the fluid is concentrated and passes near the central axis part of the fluid space.

[0090] Optionally, there are multiple first spoilers 210 arranged at intervals along the length direction of the pipe body 100, and the second spoiler 220 is arranged between two adjacent first spoilers 210. In this way, when the fluid flows through the pipe body 100, it is alternately disturbed by the first spoiler 210 and the second spoiler 220, so that each part of the fluid has the opportunity to approach the inner wall of the pipe body 100.

[0091] Figure 10 is another schematic diagram of the internal structure of the pipe body provided by the embodiments of the present disclosure. As Figure 10 shown, optionally, the second spoiler 220 includes a partition 221, and both ends of the partition 221 are respectively connected to the inner wall of the pipe body 100. In this way, the fluid channel can be divided into two second channels 102.

[0092] Optionally, the partition 221 is arranged corresponding to the first channel 101. In this way, when the fluid flows out of the first channel 101, the fluid concentrated at the central axis part can be split into the second channel 102 when it encounters the partition 221.

[0093] Optionally, as Figures 4 to 6 shown, the second spoiler 220 includes a column, and both ends of the column are respectively connected to the inner wall of the pipe body 100. The column has an arc-shaped side wall. When the fluid passes through, the resistance generated by the side wall of the column to the fluid is small, which is beneficial to the flow of the fluid.

[0094] Optionally, as Figure 4 shown, the diameter of the column is d1, the inner diameter of the pipe body 100 is d2, 1 / 4d2 ≤ d1 ≤ 1 / 2d2, and d2 ≥ 5. In this way, it is beneficial to the transportation of the fluid and the full contact with the inner wall of the pipe body 100.

[0095] Optionally, the distance between the first spoiler 210 and the second spoiler 220 is c, and a ≤ c.

[0096] Optionally, the second spoiler 220 is arranged corresponding to the first channel 101. In this way, when the fluid flows out of the first channel 101, it encounters the second spoiler 220 and can be diverted into different second channels 102.

[0097] Optionally, the fluid pipeline further includes a refrigeration device or a heating device, and the refrigeration device or the heating device is configured to refrigerate or heat the fluid pipeline. When the fluid flows through the interior of the fluid pipeline body 100, each part of the fluid has the opportunity to be close to the inner wall of the pipeline body, which is conducive to the fluid fully absorbing the cold generated by the refrigeration device or the heat generated by the heating device, thereby enhancing the refrigeration effect of the refrigeration device on the fluid or the heating effect of the heating device on the fluid.

[0098] An embodiment of the present disclosure further provides a fluid pipeline, including:

[0099] A pipeline body 100 and an electromagnetic heating device; wherein, the electromagnetic heating device includes an alternating body part 310, and the alternating body part 310 is configured to generate an alternating magnetic field when an alternating current is passed through; the pipeline body 100 is placed in the alternating magnetic field and is configured to generate an induced electromotive force under the action of the alternating magnetic field;

[0100] It further includes:

[0101] A first spoiler 210, which is configured to partially disturb the fluid in the pipeline body 100 and form a fluid passage;

[0102] A second spoiler 220, which is configured to disturb the fluid passage formed by the first spoiler 210.

[0103] Due to the skin effect of electromagnetic heating, that is, the heat generated by electromagnetic heating will concentrate on the outer surface of the pipeline body 100. When the refrigerant flows through the pipeline body 100 of the fluid pipeline in the heat exchange device, the second spoiler 220 is conducive to the refrigerant located in the middle of the pipeline body 100 flowing towards the inner wall of the pipeline body, that is, the refrigerant in the middle diffuses towards the inner wall. In this way, it is conducive to the refrigerant located in the middle of the pipeline body 100 absorbing the heat generated by electromagnetic heating on the pipeline body 100. The first spoiler 210 is conducive to the refrigerant close to the inner wall of the pipeline body 100 flowing towards the middle of the pipeline body, that is, the refrigerant near the inner wall gathers towards the middle, and then transfers the heat absorbed by the refrigerant from the inner wall of the pipeline body 100 to the refrigerant in the middle. Through the arrangement of the first spoiler 210 and the second spoiler 220, the refrigerant inside the pipeline body 110 can continuously gather and diffuse, and then absorb the heat generated by electromagnetic heating on the pipeline body more evenly, enhancing the heat exchange effect.

[0104] An embodiment of the present disclosure also provides a heat exchange device, including the aforementioned fluid pipeline.

[0105] Optionally, the heat exchange device is an outdoor heat exchanger of an air conditioner.

[0106] An embodiment of the present disclosure also provides a temperature regulation device, such as Figures 2 to 3 as shown, including a fluid pipeline, and the fluid pipeline includes:

[0107] A pipeline body 100 and an electromagnetic heating device; wherein, the electromagnetic heating device includes an alternating body portion 310, and the alternating body portion 310 is configured to generate an alternating magnetic field when an alternating current is passed through; the pipeline body 100 is placed in the alternating magnetic field and is configured to generate an induced electromotive force under the action of the alternating magnetic field.

[0108] The pipeline body 100 of the fluid pipeline is configured to provide a flow channel for the refrigerant to flow through.

[0109] Optionally, the temperature regulation device further includes one or more of a refrigeration circuit and a heating circuit, which form a conductive circuit with the pipeline body 100 of the fluid pipeline.

[0110] Optionally, one or more of the refrigeration circuit and the heating circuit include an outdoor heat exchanger 700; the fluid pipeline is arranged at the inlet of the outdoor heat exchanger 700.

[0111] Optionally, one or more of the refrigeration circuit and the heating circuit further include a throttling device 600, and the fluid pipeline is arranged between the throttling device 600 and the outdoor heat exchanger 700.

[0112] Optionally, one or more of the refrigeration circuit and the heating circuit further include a compressor 400 and an indoor heat exchanger 500.

[0113] Optionally, one or more of the refrigeration circuit and the heating circuit further include a four-way valve, and the compressor realizes the switching between the refrigeration circuit and the heating circuit through the four-way valve.

[0114] An embodiment of the present disclosure also provides a temperature regulation device, including a fluid pipeline, and the fluid pipeline includes: a first flow disturbing member 210, which is configured to perform partial flow disturbance on the fluid in the pipeline body 100 and form a flow-through;

[0115] A second flow disturbing member 220, which is configured to perform flow disturbance on the flow-through formed by the first flow disturbing member 210.

[0116] An embodiment of the present disclosure also provides a temperature regulation device, including:

[0117] A pipe body 100 and an electromagnetic heating device; wherein, the electromagnetic heating device includes an alternating body part 310 which is configured to generate an alternating magnetic field when an alternating current is passed through; the pipe body 100 is placed in the alternating magnetic field and is configured to generate an induced electromotive force under the action of the alternating magnetic field;

[0118] It further includes:

[0119] A first flow disturbing member 210 which is configured to partially disturb the fluid in the pipe body 100 and form a fluid passage;

[0120] A second flow disturbing member 220 which is configured to disturb the fluid passage formed by the first flow disturbing member 210.

[0121] When the pipe body 100 forms an electrically conductive loop with the heating circuit of the temperature regulating device, an induced current will be generated in the pipe body 100 under the action of the induced electromotive force, and then Joule heat will be generated. The pipe body 100 then transfers the Joule heat to the flowing medium inside the pipe body 100. The settings of the first flow disturbing member and the second flow disturbing member enhance the heat exchange effect of the flowing medium such as refrigerant in the pipe body 100, further increase the specific volume of the refrigerant in the heating circuit, further increase the low-temperature heating capacity of the temperature regulating device, and improve the heating effect.

[0122] Optionally, the temperature regulating device is an air conditioner.

[0123] Optionally, one or more of the refrigeration circuit and the heating circuit of the temperature regulating device include a gas-liquid separator.

[0124] Optionally, as Figure 11 shown, the gas-liquid separator includes a gas-liquid separator body 401 and an electromagnetic heating device; wherein, the electromagnetic heating device includes an alternating body part 310 which is configured to generate an alternating magnetic field when an alternating current is passed through; the gas-liquid separator body 401 is placed in the alternating magnetic field and is configured to generate an induced electromotive force under the action of the alternating magnetic field.

[0125] Optionally, the alternating body part 310 can be arranged near the side of the gas-liquid separator body 401 such that the gas-liquid separator body 401 is placed in the alternating magnetic field generated by the alternating body part 310. It can also be placed in other positions as long as the gas-liquid separator body 401 is placed in the alternating magnetic field generated by the alternating body part 310. This embodiment does not limit this.

[0126] With this embodiment, when the gas-liquid separator body 401 forms a conductive loop with an external pipeline, such as the heating circuit of an air conditioner, an induced current will be generated in the gas-liquid separator body 401 under the action of the induced electromotive force. The direction of this induced current is opposite to the direction of the driving current in the electromagnetic heating device (i.e., the input current of the alternating body 310). Therefore, Joule heat is generated in the gas-liquid separator body 401, and the gas-liquid separator body 401 then transfers the Joule heat to the circulating medium inside the gas-liquid separator body 401, thereby realizing the heating of the circulating medium, such as refrigerant, effectively increasing the specific volume of the refrigerant in the heating circuit, and further increasing the low-temperature heating capacity of the air conditioner and improving the heating effect.

[0127] Optionally, the gas-liquid separator body 401 is made of a conductor material and can generate an induced electromotive force under the action of an alternating magnetic field. When the gas-liquid separator body 401 is connected to the heating circuit of the air conditioner, the gas-liquid separator body 401 and the heating circuit form a conductive loop, and an induced current can be generated in this conductive loop under the action of the induced electromotive force.

[0128] Optionally, the gas-liquid separator body 401 is made of martensitic steel.

[0129] Optionally, a conductive path is provided on the gas-liquid separator body 401. When the gas-liquid separator body 401 is connected to the heating circuit of the air conditioner, the gas-liquid separator body 401 and the heating circuit form a conductive loop through the conductive path, and an induced current can be generated in this conductive loop under the action of the induced electromotive force.

[0130] Optionally, the electromagnetic heating device further includes a magnetic body part 320 that can surround the gas-liquid separator body 401 and is configured to concentrate the alternating magnetic field on the magnetic body part 320.

[0131] With this embodiment, since the magnetic body part 320 surrounds the gas-liquid separator body, when the alternating magnetic field is concentrated on the magnetic body part 320, this alternating magnetic field will also surround the gas-liquid separator body 401, thereby enhancing the electromagnetic field around the gas-liquid separator body to enhance the induced electromotive force. When the gas-liquid separator body 401 forms a conductive loop with an external pipeline, such as the heating circuit of an air conditioner, the enhanced induced electromotive force will cause an increase in the induced current, thereby generating more Joule heat, improving the refrigerant heating effect, effectively increasing the specific volume of the refrigerant in the heating circuit, and further increasing the low-temperature heating capacity of the air conditioner and improving the heating effect.

[0132] Optionally, the alternating body 310 is arranged on the magnetic body part 320.

[0133] Optionally, the alternating body 310 is an induction coil wound around the magnetic body part 320. When an alternating current is passed into the induction coil, the magnetic body part 320 generates an alternating magnetic field.

[0134] Optionally, the magnetic body part is a closed structure or an open structure.

[0135] Compared with the magnetic body part with an open structure, the magnetic body part with a closed structure further concentrates the alternating magnetic field on the magnetic body part 320 to further enhance the induced electromotive force and induced current, ultimately improving the refrigerant heating effect, effectively increasing the specific volume of the refrigerant in the heating circuit, and then enhancing the low-temperature heating capacity of the air conditioner and improving the heating effect.

[0136] Optionally, the magnetic body part 320 is rectangular or annular.

[0137] Optionally, the alternating body part is wound around one rectangular side of the rectangular magnetic body part; the alternating magnetic field is concentrated inside the magnetic body part.

[0138] Optionally, the position of the electromagnetic heating device is close to the compressor 400 inlet interface of the gas-liquid separator body 401.

[0139] By adopting this embodiment, the part of the gas-liquid separator body close to the compressor interface is preferentially heated, which is beneficial to concentrating heat to heat the refrigerant about to flow from the gas-liquid separator body into the compressor, thereby effectively increasing the specific volume of the refrigerant in the heating pipeline and enhancing the low-temperature heating capacity of the air conditioner.

[0140] Optionally, the gas-liquid separator body 401 is provided with a heat insulation layer. As an example, the heat insulation layer is coated on the outer surface of the gas-liquid separator body 401.

[0141] By adopting this embodiment, the alternating magnetic field directly heats the gas-liquid separator body through the heat insulation layer, with very high thermal efficiency and almost no heat energy loss. Moreover, since the gas-liquid separator body generates heat by itself under the action of the alternating magnetic field, there is also no loss of heat transfer. The overall energy saving is about 30%-70% of resistance heating under the same conditions.

[0142] Optionally, a magnetic isolation layer is provided on the alternating body part 310. As an example, the magnetic isolation layer is arranged on the outer surface of the alternating body part 310.

[0143] By adopting this embodiment, the alternating body part avoids electromagnetic interference through the magnetic isolation layer.

[0144] Optionally, a magnetic leakage prevention layer is provided on the magnetic body part 320. As an example, the magnetic leakage prevention layer is a magnetic leakage prevention paper coated on the outside of the magnetic body part 320, or a magnetic leakage prevention coating layer coated on the outside of the magnetic body part 320.

[0145] By adopting this embodiment, the magnetic leakage amount is reduced through the magnetic leakage prevention layer to ensure the electromagnetic induction heating effect.

[0146] Optionally, one or more of the refrigeration circuit and the heating circuit of the temperature adjustment device include the compressor 400 of the above-mentioned gas-liquid separator.

[0147] The embodiments of the present disclosure also provide a compressor, including the aforementioned gas-liquid separator.
