Detailed Implementation

[0068] The heating element in related technologies may include a housing cover component, a heating element, and an electrical connector, wherein the heating element and the electrical connector need to be installed into the housing cover component, such as... Figure 21 As shown, after the heating element and electrical connector are installed, the connection terminals of the electrical connector will protrude from the mounting cavity of the housing component. Therefore, during the installation of the assembly of the electrical connector and heating element, the position of the assembly needs to be adjusted, for example, as... Figure 22 As shown; after installation, adjust the assembly to its final position (e.g., Figure 21 Its assembly method is relatively complex. Furthermore, the assembly process requires rotating the assembly, necessitating a large opening in the end cap component (for connection to the connector and controller). This compromises the heater's structural strength, hinders processing, and affects sealing. The assembly can only rotate after being tilted and inserted into the designated position on the end shell assembly; premature rotation can damage the connecting terminals or cause the assembly to jam, thus potentially disrupting automated production processes.

[0069] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0070] like Figure 1 and Figure 2 According to an embodiment of the present invention, the heater 10 includes: a cover component 11, a heating component 12, and an electrical connector 13. The cover component 11 is used to provide a receiving space and protection for the heating component 12 and the electrical connector 13. The heating component 12 is used to heat the medium, and the electrical connector 13 is used to connect the heating component 12 to a power source.

[0071] The cover component 11 includes a mounting cavity 1101, and the cover component 11 may include one or more mounting cavities 1101. One end of the mounting cavity 1101 along the first direction has a mounting opening 1103 (e.g., Figure 23 (As shown). In other words, the cover component 11 includes a mounting cavity 1101 and a mounting port 1103 communicating with the mounting cavity 1101, the mounting port 1103 being opposite to the mounting cavity 1101 along a first direction.

[0072] The heating component 12 includes a first heating element 121a, a second heating element 121b, and a connecting portion 122. The first heating element 121a and the second heating element 121b are arranged side by side. The connecting portion 122 is located at one end of the heating component 12 along a first direction and connects the first heating element 121a and the second heating element 121b. The first heating element 121a and / or the second heating element 121b are provided with the heating portion 1212. The first heating element 121a and the second heating element 121b are located in the mounting cavity 1101. The first heating element 121a and the second heating element 121b have internal channels 1201. Medium can enter from the inlet of the heating component 12 and flow through the internal channels 1201. The first heating element 121a and the second heating element 121b can heat the medium flowing through the internal channels 1201. The heated medium can be discharged from the outlet of the heating component 12. At least a portion of the first heating element 121a and the second heating element 121b are located in the mounting cavity 1101. Electrical connector 13 is installed on heating component 12 and is electrically connected to heating element 1212. Electrical connector 13 is used to connect heating element 1212 to a power source, allowing heating element 1212 to heat the medium after being energized. At least a portion of electrical connector 13 is located in mounting cavity 1101. In the projection along the first direction, the assembly of electrical connector 13, first heating element 121a, and second heating element 121b is located within mounting opening 1103, allowing the assembly to be inserted into mounting cavity 1101 from mounting opening 1103 along the first direction. The projection along the first direction refers to the orthographic projection onto a projection plane along the first direction, where the projection plane is perpendicular to the first direction.

[0073] According to an embodiment of the present invention, the heater 10 is modularly designed, enabling the heating module to be quickly installed into the compressor 100 or other equipment, thus simplifying the assembly method of the heating module. Furthermore, the electrical connector 13 and the heating element 12 in the heater 10 can be assembled into a single unit and then installed into the housing cover component 11, thereby improving assembly efficiency and stability. Since the electrical connector 13 and the heating element 12 are assembled together before being installed into the housing cover component 11, the assembly space, assembly efficiency, and stability of the electrical connector 13 and the heating element 12 can be improved.

[0074] Referring to the accompanying drawings, the mounting cavity 1101 of the present invention extends along a first direction, and the first heating element 121a and the second heating element 121b extend along the first direction. Therefore, the extending direction of the mounting cavity 1101, and the extending direction of the first heating element 121a or the second heating element 121b can be set as the first direction. In the compressor 100, the heater 10 can be mounted to the end of the compressor, and the first direction can be perpendicular to the axis of the motor 40; the first direction can also be inclined at a predetermined angle to the normal plane (the plane perpendicular to the axis of the motor 40) of the motor 40.

[0075] In addition, the cover component 11 of the present invention may be configured to include a mounting surface 1102, which may be one or more. When the heater 10 is integrated into the compressor 100, the cover component 11 may be mounted to the outer shell of the compressor 100 body, and the mounting surface 1102 may be configured to face the body of the compressor 100. The cover component 11 may be connected to one end of the compressor 100 along the axis of the motor 40.

[0076] like Figure 2 In some embodiments, the first heating element 121a and the second heating element 121b are arranged side by side along the second direction. In the projection along the first direction, the ratio of the dimension L1 of at least a portion of the assembly along the third direction to the dimension L2 of the corresponding position of the mounting port 1103 along the third direction satisfies: 0.5 ≤ L1 / L2 ≤ 1, and the first direction, the second direction, and the third direction are mutually perpendicular. In other words, in the projection along the first direction, with a straight line Lo extending along the third direction and passing through the assembly as a reference, the dimension of the line segment formed by the intersection of this straight line and the mounting port 1103 is L2, and the dimension of the longest line segment formed by the intersection of this straight line and the assembly is L1. When L1 / L2 < 0.5, the ratio is too small. While the assembly can be easily inserted into the mounting cavity through the mounting port, the heating element 12 is small, resulting in limited heating efficiency and hindering the heating of the medium. Furthermore, the mounting port is too large, which is detrimental to the miniaturization of the heater. When L1 / L2 > 1, the ratio is too large, making it difficult to insert the assembly into the mounting cavity through the mounting port, which is detrimental to heater assembly. Therefore, in this invention, 0.5 ≤ L1 / L2 ≤ 1 not only improves space utilization but also facilitates the quick insertion of the assembly into the mounting cavity. For example, L1 / L2 can be set to 0.5, 0.55, 0.6, 0.64, 0.7, 0.76, 0.8, 0.83, 0.86, 0.9, 0.92, 0.96, or 1, etc.

[0077] Alternatively, setting L1 / L2 to 0.55≤L1 / L2≤0.65 can further maintain the heating efficiency of the heater and facilitate the installation of the heater onto the housing component.

[0078] like Figure 2 The first heating element 121a and the second heating element 121b are arranged side by side along the second direction. At least a portion of the electrical connector 13 is disposed between the first heating element 121a and the second heating element 121b. In the projection along the first direction, the maximum distance between the electrical connector 13 and the heating element 12 along the third direction is H1. In other words, in the projection along the first direction, the two ends of the electrical connector 13 and the two ends of the heating element along the third direction are respectively a certain distance in the third direction, and H1 is the larger of the two. The average value of the diameter of the first heating element 121a and the diameter of the second heating element 121b is D (see Appendix of this invention). Figure 2 In the example, the diameter of the first heating element 121a is equal to the diameter of the second heating element 121b, therefore the diameter of the first heating element 121a and the diameter of the second heating element 121b are both D (this is not a limitation on the scope of protection of this invention). The maximum dimension of the mounting port 1103 along the third direction at the middle of the second direction is H2, where H2 / H1 > 1; and / or, H2 / H1 > 2 - D / H1. This makes it easier to insert the assembly from the mounting port 1103 into the mounting cavity 1101. For example, H2 / H1 can be set to 1.1, 1.15, 1.18, 1.2, 1.25, 1.4, 1.5, 1.55 or 2, etc.

[0079] Alternatively, setting H2 / H1 to 1≤H2 / H1≤3.5 can further maintain the heating efficiency of the heater and facilitate the installation of the heater onto the housing component.

[0080] like Figure 1 and Figure 2 The first direction refers to the up-down direction in the attached diagram, the second direction refers to the left-right direction in the attached diagram, and the third direction refers to the front-back direction in the attached diagram.

[0081] like Figures 4 to 7 In some embodiments, the electrical connector 13 includes connection terminals (e.g., Figure 6 1324 and 1334 in the middle), the first terminal group (e.g. Figure 6 1321 and 1331 form a first terminal group) and a second terminal group (1322 and 1332 form a second terminal group). The first terminal group is electrically connected to the first heating element 121a, and the second terminal group is electrically connected to the second heating element 121b. The connecting terminal is electrically connected to the first terminal group and the second terminal group. The connecting terminal is used to connect the heating element 12 to the power supply.

[0082] Reference Figure 2 In the projection along the first direction, the connecting terminal extends out of the first reference surface 1051 along the third direction to facilitate a stable connection between the connecting terminal and the power supply, which is beneficial for the electrical connection of the heater 10 with other components. Through the above arrangement, it is possible to facilitate the connection of the heater 10 to the electrical control device, while also avoiding the connecting terminal from affecting the insertion of the assembly into the mounting cavity 1101, thereby improving the assembly efficiency and effect of the heater 10.

[0083] In addition, such as Figure 2 At least a portion of the electrical connector 13 is disposed between the first heating element 121a and the second heating element 121b. This facilitates the connection between the electrical connector 13 and the first heating element 121a and the second heating element 121b, and allows for convenient control of the power supply to the first heating element 121a and the second heating element 121b. Furthermore, it optimizes the space occupied by the heater 10 and improves space utilization.

[0084] Additionally, a connecting portion 122 may be provided at the end of the heating element 12. The connecting portion 122 may be connected to the first heating body 121a and the second heating body 121b, and the first heating body 121a and the second heating body 121b may be connected through the connecting portion 122. Optionally, one end of the first heating body 121a may be set as the inlet of the heating element 12, and the other end may be connected to the connecting portion 122; one end of the second heating body 121b may be connected to the connecting portion 122, and the other end may be set as the outlet of the heating element 12.

[0085] Among them, such as Figure 2 The connecting terminals extend along a third direction, facilitating connection to controllers or other devices and enabling modular production and assembly of the heater 10. An insulating frame 131 is located between the first heating element 121a and the second heating element 121b, with one end of the connecting terminal connected to the insulating frame 131 along the third direction. Furthermore, at least two connecting terminals are spaced apart along a first direction, and these terminals can be flush along the first direction. This simplifies the structure of the connecting terminals and facilitates connection.

[0086] The mounting cavity 1101 includes a first side, a second side, a third side, and a fourth side. The first and second sides are opposite each other along a third direction, and the third and fourth sides are opposite each other along a second direction. The first side connects to the third and fourth sides along its two sides in the second direction, and the second side connects to the third and fourth sides along its two sides in the second direction. The first and third sides have rounded corners, and the second and fourth sides have a curved transition. The first, second, third, and fourth sides extend along the first direction to be flush with the mounting opening 1103.

[0087] The mounting port 1103 includes a first side, a second side, a third side, and a fourth side. The first and second sides are opposite each other along a third direction, and the third and fourth sides are opposite each other along a second direction. The two sides of the first side along the second direction are respectively connected to the third and fourth sides, and the two sides of the second side along the second direction are respectively connected to the third and fourth sides. The first and third sides have rounded corners, and there is a rounded corner between the first and fourth sides. The second and third sides have an arc transition, and there is an arc transition between the second and fourth sides.

[0088] The placement of the first terminal group and the second terminal group in this invention may include, but is not limited to, the following embodiments.

[0089] In one embodiment, a first terminal group and a second terminal group are disposed between a first heating element 121a and a second heating element 121b, and the first terminal group and the second terminal group are located between a first reference surface 1051 and a second reference surface 1052. This facilitates the assembly of the heater, reduces the size of the assembly along a third direction, and is beneficial for the miniaturization of the heater. It also makes it easy to install the assembly into the end shell assembly.

[0090] In the second embodiment, at least a portion of the first terminal group is disposed on the side of the first heating element 121a along the second direction.

[0091] In the third embodiment, at least a portion of the second terminal group is disposed on the side of the second heating element 121b along the second direction.

[0092] The first reference surface 1051 and the second reference surface 1052 are spaced apart along a third direction and are tangent to the outer surface of the first heating element 121a and the outer surface of the second heating element 121b.

[0093] In combination with the foregoing, such as Figures 1 to 3 In one specific embodiment of the present invention, the cover component 11 has a mounting cavity 1101 extending in the vertical direction. The upper end of the mounting cavity 1101 is open to form a mounting opening 1103. The inner side of the mounting opening 1103 is flush with the inner side of the mounting cavity 1101. The heating component 12 includes a first heating element 121a and a second heating element 121b, which extend in the vertical direction and are spaced apart in the horizontal direction. The outer surface of the first heating element 121a is provided with a heating portion 1212. The outer surface of the second heating element 121b is provided with a heating part 1212. At least a part of the electrical connector 13 is disposed between the first heating element 121a and the second heating element 121b. The electrical connector 13 includes two terminal groups, which are electrically connected to the heating parts 1212 of the first heating element 121a and the second heating element 121b, respectively. The connecting terminal is electrically connected to the two terminal groups. The number of connecting terminals can be two or three. Multiple connecting terminals are distributed in the vertical direction. Multiple connecting terminals can be connected to other electronic components in the front-back direction to realize the connection of power supply.

[0094] like Figure 4 and Figure 5In some embodiments, heating portions 1212 may be provided on the surfaces of the first heating element 121a and the second heating element 121b. The heating portion 1212 may include at least two electrode patches 1213 to facilitate heating using electrical energy input from the electrode patches 1213. Both the first terminal group and the second terminal group include at least two electrode terminals, which are stacked and electrically connected to their corresponding electrode patches 1213. Achieving electrical connection between the electrode terminals and electrode patches 1213 through stacking simplifies the assembly structure of the heater 10, reduces the space occupied by the heater 10, and improves space utilization.

[0095] Optionally, the electrode terminals abut against the corresponding electrode patches 1213 and are electrically connected by soldering or spring clamping.

[0096] like Figure 12 as well as Figure 16 In some embodiments, the electrical connector 13 further includes an insulating frame 131, and the connecting terminal, the first terminal group and the second terminal group are disposed on the insulating frame 131.

[0097] The electrical connector 13 also includes connecting bridges (1323, 1333, 1342, 1352, 1363), which electrically connect the connecting terminals, the first terminal group, and the second terminal group. At least a portion of the connecting bridge is encased in the insulating frame 131, and at least a portion of the connecting terminals extends out of the insulating frame 131 for connecting to a power source. The connecting bridge is used to electrically connect the connecting terminals to the first terminal group and the second terminal group. By encasing the connecting bridge in the insulating frame 131, insulation can be achieved between the connecting bridge and other components, and the relative distance between different parts of the connecting bridge can also be maintained, thereby achieving relative insulation between different parts of the connecting bridge. In addition, the cooperation between the connecting bridge and the insulating frame 131 can maintain structural strength and stability.

[0098] Optionally, the connecting terminals include a plurality of terminals extending in the same direction and located on the same side of the insulating frame 131. For example, the electrical connector 13 includes two connecting terminals, both extending in the same direction (e.g., both extending in the front-rear direction in the figures), and both terminals are located on the same side of the insulating frame 131 (e.g., both located on the front side of the insulating frame 131 in the figures); or, for example, the electrical connector 13 includes three connecting terminals, both extending in the same direction (e.g., both extending in the front-rear direction in the figures), and all three terminals are located on the same side of the insulating frame 131 (e.g., all located on the front side of the insulating frame 131 in the figures); or, for example, two of the three connecting terminals extend in the same direction (e.g., both extending in the front-rear direction in the figures), and both terminals are located on the same side of the insulating frame 131 (e.g., both located on the front side of the insulating frame 131 in the figures), and so on. Of course, the above examples are merely specific examples of the present invention and are not intended to limit the scope of protection of the present invention. With the above configuration, it is convenient to connect electronic devices using the connecting terminals.

[0099] The first terminal group and the second terminal group each include at least two electrode terminals arranged in pairs, and the at least two electrode terminals arranged in pairs are located on the same side of the insulating frame 131. The conductive coating of the first heating element 121a and the second heating element 121b can be a continuous strip, so that each end of the conductive coating can be connected to an electrode terminal (a total of two electrode terminals) or the two ends and the middle of the conductive coating can be connected to an electrode terminal (a total of three electrode terminals).

[0100] like Figures 4 to 19 The electrode terminals of the electrical connector 13 are in one-to-one contact with the electrode patch 1213, which can connect the first heating element 121a and the second heating element 121b in parallel to realize synchronous electrical connection of the two heating elements, or asynchronous electrical connection of the two heating elements.

[0101] Some embodiments of the present invention will now be described with reference to the accompanying drawings.

[0102] Implementation Method 1 like Figures 4 to 12 The first heating element 121a and the second heating element 121b can be arranged side by side. The electrical connector 13 includes a first conductive bus 132 and a second conductive bus 133. The first conductive bus 132 and the second conductive bus 133 can be distributed along the extension direction of the first heating element 121a or the second heating element 121b. The electrical connector 13 also includes an insulating frame 131. The first conductive bus 132 and the second conductive bus 133 are connected to the insulating frame 131. The conductive bus can be a copper bus or other metal bus, etc.

[0103] like Figure 6 , Figure 9 , Figure 11 as well as Figure 12 The first conductive bus 132 includes a first electrode terminal 1321, a second electrode terminal 1322, a first connecting bridge 1323, and a first connecting terminal 1324, which are electrically connected. The second conductive bus 133 includes a third electrode terminal 1331, a fourth electrode terminal 1332, a second connecting bridge 1333, and a second connecting terminal 1334, which are electrically connected. The first electrode terminal 1321 and the third electrode terminal 1331 are connected to the first heating element 121a, and the second electrode terminal 1322 and the fourth electrode terminal 1332 are connected to the second heating element 121b.

[0104] The first electrode terminal 1321 and the second electrode terminal 1322 are disposed on both sides of the first connecting bridge 1323, and the third electrode terminal 1331 and the fourth electrode terminal 1332 are disposed on both sides of the second connecting bridge 1333. The first electrode terminal 1321 and the second electrode terminal 1322 can be respectively arranged on both sides of the extension direction of the first connecting terminal 1324, and the third electrode terminal 1331 and the fourth electrode terminal 1332 can be respectively arranged on both sides of the extension direction of the second connecting terminal 1334.

[0105] The first heating element 121a and the second heating element 121b are connected in parallel and synchronously electrically using the electrical connector 13. The first electrode terminal 1321 is electrically connected to the electrode patch 1213 of the first heating element 121a, the second electrode terminal 1322 is electrically connected to the electrode patch 1213 of the second heating element 121b, the third electrode terminal 1331 is electrically connected to the electrode patch 1213 of the first heating element 121a, and the fourth electrode terminal 1332 is electrically connected to the electrode patch 1213 of the second heating element 121b.

[0106] One of the first connection terminal 1324 and the second connection terminal 1334 constitutes the positive input terminal, and the other constitutes the negative input terminal. When an external power supply is input, the first heating element 121a and the second heating element 121b operate simultaneously. The first electrode terminal 1321 and the third electrode terminal 1331 are combined to form a first terminal group, and the second electrode terminal 1322 and the fourth electrode terminal 1332 are combined to form a second terminal group.

[0107] Implementation Method 2 like Figures 13 to 16The electrical connector 13 includes a third conductive bus 134, a fourth conductive bus 135, and a fifth conductive bus 136. The electrical connector 13 also includes an insulating frame 131. The third conductive bus 134, the fourth conductive bus 135, and the fifth conductive bus 136 are connected to the insulating frame 131. The conductive bus can be a copper bus or other metal bus.

[0108] The third conductive bus 134 includes a fifth electrode terminal 1341, a third connecting bridge 1342, and a third connecting terminal 1343, which are electrically connected. The fourth conductive bus 135 includes a sixth electrode terminal 1351, a fourth connecting bridge 1352, and a fourth connecting terminal 1353, which are electrically connected. The fifth conductive bus 136 includes a seventh electrode terminal 1361, an eighth electrode terminal 1362, a fifth connecting bridge 1363, and a fifth connecting terminal 1364, which are electrically connected. The fifth electrode terminal 1341 and the seventh electrode terminal 1361 are connected to the first heating element 121a, and the sixth electrode terminal 1351 and the eighth electrode terminal 1362 are connected to the second heating element 121b. The fifth electrode terminal 1341 and the sixth electrode terminal 1351 can be arranged on both sides of the third connecting bridge 1342 and the fourth connecting bridge 1352, and the seventh electrode terminal 1361 and the eighth electrode terminal 1362 can be arranged on both sides of the fifth connecting bridge 1363.

[0109] The third connection terminal 1343 and the fourth connection terminal 1353 constitute the first input terminal, and the fifth connection terminal 1364 constitutes the second input terminal. One of the first input terminal and the second input terminal is the positive input terminal and the other is the negative input terminal. The fifth electrode terminal 1341 and the seventh electrode terminal 1361 combine to form the first terminal group, and the sixth electrode terminal 1351 and the eighth electrode terminal 1362 combine to form the second terminal group.

[0110] The first heating element 121a and the second heating element 121b are connected in parallel via electrical connector 13 to achieve an asynchronous electrical connection scheme. The seventh electrode terminal 1361 and the eighth electrode terminal 1362 of the fifth conductive bus 136 are arranged away from the fifth electrode terminal 1341 of the third conductive bus 134 and the sixth electrode terminal 1351 of the fourth conductive bus 135. The third connection terminal 1343, the fourth connection terminal 1353 and the fifth connection terminal 1364 are arranged at intervals along the extending direction of the first heating element 121a and the second heating element 121b. The third connection terminal 1343 constitutes the first input negative terminal, the fourth connection terminal 1353 constitutes the second input negative terminal, and the fifth connection terminal 1364 constitutes the input positive terminal. When there is an external power supply input, the first input negative terminal and the input positive terminal can control the first heating element 121a to work; the second input negative terminal and the input positive terminal can control the second heating element 121b to work; when there are inputs to the first input negative terminal, the second input negative terminal, and the positive terminal, the first heating element 121a and the second heating element 121b can work simultaneously.

[0111] In some embodiments, the first terminal group is attached to the first heating element 121a, and the contact surface between the first terminal group and the first heating element 121a is not higher than the highest point in the diameter direction of the first heating element 121a; the second terminal group is attached to the second heating element 121b, and the contact surface between the second terminal group and the second heating element 121b is not higher than the highest point in the diameter direction of the second heating element 121b. This improves the space utilization of the heater 10.

[0112] Optionally, the electrical connector 13 also includes a fixing part, which is connected to the heating element 12. The fixing part can be used to stably install the electrical connector 13 to the heating element 12, effectively improving the stability and safety of the connection structure between the electrical connector 13 and the heating element 12.

[0113] The heating component 12 includes a first heating element 121a and a second heating element 121b, and a fixing part connects the first heating element 121a and the second heating element 121b.

[0114] like Figures 17 to 19In some embodiments, the electrical connector 13 further includes an insulating frame 131. A first terminal group, a second terminal group, and a connecting terminal are disposed on the insulating frame 131. The insulating frame 131 extends to form a first support 1311 and a second support 1312, which together constitute a fixing portion. The first support 1311 is connected to the first heating element 121a, and the second support 1312 is connected to the second heating element 121b. The fixing portion can be constructed using a portion of the insulating frame 131, which improves the connection strength between the insulating frame 131 and the fixing portion and simplifies the structure of the insulating frame 131. The first support 1311 can be connected to the first heating element 121a by adhesive or other means, and the second support 1312 can be connected to the second heating element 121b by adhesive or other means.

[0115] In addition, such as Figures 8-12 The fixing part may also include at least a portion of a metal support that is wrapped around the insulating frame 131, and the metal support is fixedly connected to the first heating element 121a and the second heating element 121b. Using the metal support to connect the fixing part and the heating element 12 can improve the connection strength between the insulating frame 131 and the heating element 12. The metal support has a first leg 1313 and a second leg 1314 exposed above the insulating frame 131. The first leg 1313 is fixedly connected to the first heating element 121a, and the second leg 1314 is fixedly connected to the second heating element 121b. The fixing part and the heating element can be fixedly connected by welding.

[0116] like Figure 1 and Figure 4 In some embodiments, the heater 10 further includes a mounting plate 14, which is integrally connected to the heating element 12. The mounting plate 14 covers the mounting opening 1103. The first heating element 121a, the second heating element 121b, and the electrical connector 13 are disposed on one side of the mounting plate 14 and in the mounting cavity 1101. The mounting plate 14 can be integrally connected to the heating element 12 by welding, integral molding, bolting, or adhesive bonding. Thus, during the installation of the heating element 12, after the assembly of the heating element 12 and the electrical connector 13 is inserted into the mounting cavity 1101, the mounting plate 14 naturally covers the mounting opening 1103, simplifying the structure of the heater 10 and improving its assembly efficiency.

[0117] like Figure 20Both the first heating element 121a and the second heating element 121b include a base 1211 and a heating element 1212. A medium channel is formed inside the base 1211, and the heating element 1212 is laid on the outer surface of the base 1211. The base 1211 can be configured as a tube, and the heating element 1212 can heat the medium passing through the base 1211. The heating element 1212 can be disposed on the inner surface and / or outer surface of the corresponding base 1211, or at least a portion of the heating element 1212 can be embedded between the inner surface and the outer surface of the corresponding tube.

[0118] Optionally, the heating element 1212 includes a stacked insulating coating, a heating coating, a conductive coating, and a protective coating, with the insulating coating stacked on the surface of the substrate 1211. The heating element 1212 is a thick-film heating element, and placing it on the surface of the substrate 1211 simplifies the structure of the heater 10 and improves heating efficiency and effect. The insulating coating can be stacked on the inner or outer surface of the substrate 1211. The substrate 1211 can be configured as a cylindrical tube, a square tube, or other shapes.

[0119] Optionally, the inlet and outlet of the heating element 12 are connected to the medium channels within the first heating body 121a and the second heating body 121b, and the inlet and outlet are located at the same end of the heating element 12. This simplifies the structure of the heating element 12 and facilitates the external piping of the heating element 12.

[0120] like Figure 2 After the electrical connector 13 is connected to the heating component 12, it is installed in the mounting cavity 1101 of the cover component 11. The height of the connection terminal of the electrical connector 13 must not exceed the mounting cavity 1101.

[0121] The electrode terminals of the electrical connector 13 are electrically connected to the electrode patches 1213 of the heating element 12. The electrode patches 1213 are disposed on the outer surfaces of the first heating element 121a and the second heating element 121b. The height of the mating surfaces between the electrode terminals of the electrical connector 13 and the first heating element 121a and the second heating element 121b does not exceed the diametrical height of the first heating element 121a and the second heating element 121b. The electrical connector 13 is provided with a fixing device to avoid stress on the electrode patches 1213 of the heating element 12 and improve the reliability of the heating element 12.

[0122] The present invention also provides a heater 10, comprising: a heating element 12, an electrical connector 13, and a mounting plate 14. The heating element 12 is used to heat a medium, and the electrical connector 13 is used to connect the heating element 12 to a power source. The heating element 12 includes a first heating body 121a, a second heating body 121b, and a connecting portion 122. The first heating body 121a and the second heating body 121b are arranged side by side. The connecting portion 122 is located at one end of the heating element 12 along a first direction and connects the first heating body 121a and the second heating body 121b. The first heating body 121a and / or the second heating body 121b are provided with the heating portion 1212. The first heating body 121a and the second heating body 121b have internal channels 1201, through which the medium can enter from the inlet of the heating element 12 and flow through the internal channels 1201. The first heating body 121a and the second heating body 121b can heat the medium flowing through the internal channels 1201, and the heated medium can be discharged from the outlet of the heating element 12. Electrical connector 13 is installed on heating component 12 and is electrically connected to heating element 1212. Electrical connector 13 is used to connect heating element 1212 to a power source, allowing heating element 1212 to heat the medium after being energized. First heating element 121a, second heating element 121b, and electrical connector 13 are located on one side of mounting plate 14. Wherein, as... Figure 26 In the projection along the first direction, the assembly of electrical connector 13, first heating element 121a, and second heating element 121b is located inside the outer periphery of mounting plate 14. The heater 10 of this invention can be installed into the mounting cavity 1101 of the cover component 11. When the heater 10 is installed into the cover component 11, the periphery of mounting plate 14 mates with the periphery of mounting opening 1103, and mounting plate 14 will close the mounting cavity 1101. Figure 23 The dimensions of the mounting plate 14 perpendicular to the first direction are similar to those of the mounting opening 1103. With the above arrangement, the heater 10 can be more easily installed into the mounting cavity 1101, thereby improving assembly efficiency.

[0123] In some embodiments, such as Figure 26The first heating element 121a and the second heating element 121b are arranged side by side along the second direction. In the projection along the first direction, the ratio of the dimension L1 of at least a portion of the assembly along the third direction to the dimension L3 of the corresponding position of the mounting plate 14 along the third direction satisfies: 0.5 ≤ L1 / L3 ≤ 1, and the first direction, the second direction, and the third direction are mutually perpendicular. In other words, taking the straight line Lo extending along the third direction and passing through the assembly as a reference, the dimension of the line segment formed by the intersection of this straight line and the edge of the mounting plate 14 is L3, and the dimension of the longest line segment formed by the intersection of this straight line and the assembly is L1. In this invention, 0.5 ≤ L1 / L3 ≤ 1 not only improves space utilization but also facilitates the quick insertion of the assembly into the mounting cavity 1101. For example, L1 / L3 can be set to 0.5, 0.55, 0.6, 0.64, 0.7, 0.76, 0.8, 0.83, 0.86, 0.9, 0.92, 0.96, or 1, etc.

[0124] Alternatively, setting L1 / L3 to 0.55≤L1 / L3≤0.65 can further maintain the heating efficiency of the heater and facilitate the installation of the heater into the compressor.

[0125] like Figure 26 The first heating element 121a and the second heating element 121b are arranged side by side along the second direction, and at least a portion of the electrical connector 13 is disposed between the first heating element 121a and the second heating element 121b.

[0126] In some embodiments, such as Figure 26 In the projection along the first direction, the maximum distance between the electrical connector 13 and the heating element 12 along the third direction is H1. In other words, in the projection along the first direction, the two ends of the electrical connector 13 along the third direction and the two ends of the heating element along the third direction each have a certain distance in the third direction, and H1 is the larger of the two. The average value of the diameter of the first heating element 121a and the diameter of the second heating element 121b is D (see Appendix of this invention). Figure 2 In the example, the diameter of the first heating element 121a is equal to the diameter of the second heating element 121b, therefore the diameter of the first heating element 121a and the diameter of the second heating element 121b are both D (this is not a limitation on the scope of protection of the present invention). The maximum dimension of the mounting opening 1103 along the third direction at the middle of the second direction is H3, where H3 / H1 > 1; and / or, H3 / H1 > 2 - D / H1. This makes it easier to insert the assembly into the mounting cavity 1101. The first direction, the second direction, and the third direction are perpendicular to each other. For example, H3 / H1 can be set to 1.1, 1.15, 1.18, 1.2, 1.25, 1.4, 1.5, 1.55, or 2, etc.

[0127] Alternatively, setting H3 / H1 to 1≤H3 / H1≤3.5 can further maintain the heating efficiency of the heater and facilitate the installation of the heater into the compressor.

[0128] like Figure 23 According to an embodiment of the present invention, the compressor 100 includes a first housing 21, a second housing 22, a compression section 30, a motor 40, an electronic control device 50, and the aforementioned heater 10; a cover member 11 is disposed on one side of the first housing 21, and the cover member 11 and the first housing 21 define a receiving cavity 201, and the electronic control device 50 is disposed in the receiving cavity 201; the compression section 30 and the motor 40 are disposed on the other side of the first housing 21 and are disposed between the first housing 21 and the second housing 22; an electrical connector 13 is electrically connected to the electronic control device 50, and the motor 40 is electrically connected to the electronic control device 50, and the electrical connector 13 and the motor 40 share the electronic control device 50.

[0129] In conjunction with the foregoing, the heater 10 includes a housing cover component 11, an electrical connector 13, and a heating component 12; the heating component 12 includes one or at least two heating elements, at least a portion of the first heating element 121a and the second heating element 121b are disposed in the receiving cavity 201, the first heating element 121a and the second heating element 121b include a base 1211 and a heating portion 1212, the outer peripheral wall of the base 1211 is provided with the heating portion 1212; the first heating element 121a and the second heating element 121b are electrically connected through the electrical connector 13, and can be electrically connected to an independent heater 10 controller. The compressor 100 includes a first housing 21, a second housing 22, a compression section 30, a motor 40, an electronic control device 50, and a heater 10. The cover component 11 of the heater 10 and one side of the first housing 21 define a receiving cavity 201. The electronic control device 50 is disposed in the receiving cavity 201 and electrically connected to the motor 40. The compression section 30 and the motor 40 are located in the area between the other side of the first housing 21 and the second housing 22, and the motor 40 is drively connected to the compression section 30. The heater 10 is electrically connected to the electronic control device 50 via an electrical connector 13. The technical solution provided by this invention aims to simplify and stabilize the electrical connector 13 connecting the heater 10 to the electronic control device 50, reduce the volume of the heater 10 and the compressor 100, and thus reduce installation difficulty.

[0130] like Figure 24 According to an embodiment of the present invention, a thermal management system 1000 is characterized in that it includes the aforementioned heater 10; or includes the aforementioned compressor 100. Figure 25 According to an embodiment of the present invention, the vehicle 10000 is characterized in that it includes the aforementioned heater 10; or includes the aforementioned compressor 100; or includes the aforementioned thermal management system 1000.
