Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of air conditioners, and in particular to a mounting bracket and an air conditioner having the same. Background Technology
[0002] The air conditioner in the related technology includes a compressor, a thermistor for detecting the compressor temperature, and a mounting bracket. The mounting bracket is fixedly mounted on the compressor end cover, forming an open mounting space together with the end cover. The thermistor is inserted into the mounting space through the open end. A pressure plate is provided within the mounting space to press the thermistor against the end cover, allowing heat from the compressor to be conducted to the thermistor. However, because the surface of the compressor end cover in the related technology is flat, while the thermistor is cylindrical, and an insulating sleeve is fitted on the outer circumference of the thermistor, the thermistor is pressed at an angle against the surface of the compressor end cover. This results in an excessively small contact area between the thermistor and the compressor end cover, severely affecting the heat conduction between them and causing a decrease in the accuracy of the thermistor. Utility Model Content
[0003] In view of the above problems, the present invention is proposed to provide a mounting bracket and an air conditioner having the above problems in order to overcome or at least partially solve the above problems.
[0004] One objective of this invention is to solve the problem of poor heat conduction between the thermistor and the compressor end cover in related technologies, so as to improve the detection accuracy of the thermistor.
[0005] Specifically, this utility model provides a mounting bracket for a thermistor.
[0006] This utility model provides an air conditioner having the aforementioned mounting bracket for a thermistor.
[0007] The mounting bracket for a thermistor of this utility model includes: a thermally conductive base, the thermally conductive base being made of a thermally conductive material, the thermally conductive base being provided with a groove for fitting against a portion of the outer surface of the thermistor; and a pressing member, disposed on the thermally conductive base and configured to press the thermistor onto the groove.

[0009] In some embodiments, the angle between the axial direction of the first region and the surface is 2° to 7°.
[0010] In some embodiments, the crimping member includes: a surrounding plate disposed on the thermally conductive base and defining a receiving space for mounting the thermistor, the groove being located on the bottom wall of the receiving space; the receiving space being open at one end away from the second region; and at least one pressing plate disposed within the receiving space and connected to the top wall of the receiving space.
[0011] In some embodiments, at least one of the compression plates includes a first compression plate and a second compression plate, the first compression plate being located at an open end near the receiving space relative to the second compression plate; one end of the first compression plate is connected to the top wall of the receiving space, and the other end is a free end; one end of the second compression plate is connected to the top wall of the receiving space, and the other end is a free end; the distance between the free end of the first compression plate and the bottom wall of the receiving space is greater than the distance between the free end of the second compression plate and the bottom wall of the receiving space.
[0012] In some embodiments, the line connecting the end of the first pressing plate near the surface and the end of the second pressing plate near the surface is parallel to the axial direction of the first region.
[0013] In some embodiments, the end of the heat-conducting base away from the second region has a clearance notch; and / or, the distance between the inner wall surface of the clearance notch and the first region is 0 mm to 3 mm.
[0014] In some embodiments, the thickness of the thermally conductive base is 0.8 mm to 1.5 mm.
[0015] The air conditioner of this utility model includes: a compressor, which includes an end cover; a mounting bracket as described in any of the above claims, wherein the base is fixedly connected to the end cover; and a thermistor, wherein the thermistor is mounted on the mounting bracket and the outer surface of the thermistor is in contact with the groove.
[0016] In some embodiments, a portion of the thermistor is abutted against a groove on the thermally conductive base; the ratio between the area of the portion of the thermistor abutting against the groove of the mounting bracket and the surface area of the thermistor is 1 / 8 to 1 / 3.
[0017] The mounting bracket for the thermistor according to this embodiment of the invention has a heat-conducting base made of a heat-conducting material, allowing the heat from the compressor to be normally conducted to the thermistor through the heat-conducting base. Furthermore, the heat-conducting base is provided with a groove that partially conforms to the outer surface of the thermistor. This significantly increases the contact area between the thermistor and the heat-conducting base, thereby improving the heat conduction effect between the thermistor and the heat-conducting base.

[0039] The air conditioner 20 of this utility model is described below with reference to the accompanying drawings.
[0040] like Figures 1-8 As shown, the air conditioner 20 of this embodiment includes a compressor 400, a thermistor 300, and a mounting bracket 10 for mounting the thermistor 300. The compressor 400 includes an end cover 410, and the base of the mounting bracket 10 is fixedly mounted on the outer surface of the end cover 410. The mounting bracket 10 can be fixed to the outer surface of the end cover 410 by welding; alternatively, it can be fixed to the outer surface of the end cover 410 by screws or bolts; or it can be fixed to the outer surface of the end cover 410 by other means. The thermistor 300 is mounted on the mounting bracket 10 to be mounted on the end cover 410 of the compressor 400, thereby detecting the temperature of the compressor 400.
[0041] The mounting bracket 10 for a thermistor 300 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0042] like Figures 1-7 As shown, the mounting bracket 10 for the thermistor 300 in this embodiment of the present invention includes a thermally conductive base 100 and a crimping member 200.
[0043] The thermally conductive base 100 is made of a thermally conductive material, such as copper, aluminum nitride, or graphite. The thermal conductivity of the material is greater than or equal to 100 W / (m·K). The thermally conductive base 100 has a groove 110 for contacting a portion of the outer surface of the thermistor 300. Specifically, the inner wall of the groove 110 is contoured to fit the outer surface of the thermistor 300, allowing for a large contact area between the inner wall of the groove 110 and a portion of the outer surface of the thermistor 300.
[0044] A crimping member 200 is disposed on the thermally conductive base 100. The crimping member 200 is configured to press the thermistor 300 onto the groove 110. That is, the crimping member 200 can apply a force toward the groove 110 to the thermistor 300, so that the thermistor 300 is pressed onto the groove 110. On the one hand, this ensures that a portion of the outer surface of the thermistor 300 is in close contact with the groove 110, guaranteeing that the inner wall of the groove 110 is in contact with the outer surface of the thermistor 300. On the other hand, this ensures that the thermistor 300 is stably pressed onto the groove 110, preventing the thermistor 300 from falling off the mounting bracket 10.
[0045] In related technologies, air conditioners use mounting brackets that directly press the thermistor onto the compressor's end cover. Because the thermistor itself is cylindrical and has an insulating sleeve on one end, it can only be pressed onto the end cover at an axial angle. Therefore, the thermistor and end cover only have point contact, resulting in an excessively small contact area and reduced thermistor accuracy. Even if the thermistor is not equipped with an insulating sleeve, and its outer circumference has line contact with the end cover, the contact area is still relatively small.
[0046] Compared with related technologies, the mounting bracket 10 for the thermistor 300 in this embodiment of the present invention has a heat-conducting base 100 made of a heat-conducting material, allowing the heat from the compressor 400 to be normally conducted to the thermistor 300 through the heat-conducting base 100. Furthermore, the heat-conducting base 100 is provided with a groove 110 that partially conforms to the outer surface of the thermistor 300. This significantly increases the contact area between the thermistor 300 and the heat-conducting base 100, thereby improving the heat conduction effect between the thermistor 300 and the heat-conducting base 100, allowing the heat from the compressor 400 to be more fully conducted to the thermistor 300, thus improving the detection accuracy of the thermistor 300.
[0047] In some embodiments, the ratio between the area of the portion of the thermistor 300 that contacts the groove 110 of the mounting bracket 10 and the surface area of the thermistor 300 is 1 / 8 to 1 / 3. That is, the ratio between the area of the portion of the thermistor 300 that contacts the groove 110 of the mounting bracket 10 and the surface area of the thermistor 300 is, but is not limited to, 1 / 8, 1 / 7, 1 / 6, 1 / 5, 1 / 4, or 1 / 3. This results in a larger contact area between the thermistor 300 and the thermally conductive base 100, improving the heat conduction between the thermistor 300 and the thermally conductive base 100.
[0048] In some embodiments, such as Figures 1-5 As shown, the groove 110 is disposed on the surface of one side of the heat-conducting base 100. That is, the heat-conducting base 100 includes a first surface 131 and a second surface 132 opposite to each other in its thickness direction, the groove 110 is disposed on the first surface 131, and the second surface 132 is in contact with the end cover 410 of the compressor 400.
[0049] The wall surface of the groove 110 includes a first region 111 and a second region 112. The first region 111 is an arcuate surface, inclined relative to the surface 131, and configured to contact the peripheral wall surface of the thermistor 300. That is, the axial direction of the arcuate surface of the first region 111 is inclined relative to the first surface 131, and the shape of the arcuate surface is a portion of a cylindrical surface consistent with the outer peripheral surface structure of the thermistor 300. The second region 112 is connected to the first region 111 and configured to contact the end face of the thermistor 300. That is, the second region 112 is connected to one axial end of the first region 111, and the second region 112 is adapted to the end face of one end of the thermistor 300. For example, the end face of one end of the thermistor 300 is a plane, and the second region 112 is also a plane.
[0050] The thermistor 300 includes a first segment 310 and a second segment (not shown) along its axial direction, with an insulating sleeve 330 fitted onto the second segment. When the thermistor 300 is installed in the groove 110, the first segment 310 is in contact with the groove 110, and the second segment is located outside the groove 110. The first region 111 is inclined to prevent the insulating sleeve 330 on the second segment from interfering with the contact between the first segment 310 and the groove 110.
[0051] When the thermistor 300 is installed in the groove 110, both the first region 111 and the second region 112 are in contact with the thermistor 300, thereby ensuring a large contact area between the thermistor 300 and the groove 110. Furthermore, the second region 112 can also restrict the axial movement of the thermistor 300 in the first region 111, thus limiting the thermistor 300 and improving the stability of its installation.
[0052] Optionally, the angle between the axial direction of the first region 111 and the first surface 131 is 2° to 7°. Optionally, the angle between the axial direction of the first region 111 and the first surface 131 is 3° to 6°. Optionally, the angle between the axial direction of the first region 111 and the first surface 131 is 4° to 5°. This not only ensures that the insulating sleeve 330 on the second segment does not interfere with the contact between the first segment 310 and the groove 110, but also prevents the difference between the distance between one end of the groove 110 and the compressor 400 in the axial direction and the distance between the other end of the groove 110 and the compressor 400 from being too large, ensuring that the thermistor 300 is heated evenly, thus further improving the accuracy of the thermistor 300.
[0053] The angle between the axial direction of the first region 111 and the first surface 131 is, but is not limited to, 2°, 3°, 4°, 5°, 6° or 7°.
[0054] In some embodiments, such as Figures 1-5 As shown, the crimping member 200 includes a surrounding plate 210 and a pressing plate. The surrounding plate 210 is disposed on the thermally conductive base 100 and defines a receiving space 220 for mounting the thermistor 300. A groove 110 is located on the bottom wall 221 of the receiving space 220. The receiving space 220 is open at one end away from the second region 112. At least one pressing plate is disposed within the receiving space 220 and is connected to the top wall 222 of the receiving space 220. The thermistor 300 is crimped onto the groove 110 using at least one pressing plate, thereby stably mounting the thermistor 300 in the receiving space 220.
[0055] The tablet can extend toward the open end close to the receiving space 220 or toward the open end away from the receiving space 220.
[0056] When there are multiple tablets, a portion of the tablets extends toward the open end closer to the receiving space 220, and another portion extends toward the open end farther from the receiving space 220. Alternatively, all the tablets extend toward the open end closer to the receiving space 220. Alternatively, all the tablets extend toward the open end farther from the receiving space 220.
[0057] In some embodiments, such as Figures 1-5As shown, at least one pressure plate includes a first pressure plate 230 and a second pressure plate 240, with the first pressure plate 230 positioned relative to the second pressure plate 240 at its open end near the receiving space 220. One end of the first pressure plate 230 is connected to the top wall 222 of the receiving space 220, and the other end of the first pressure plate 230 is a free end. One end of the second pressure plate 240 is connected to the top wall 222 of the receiving space 220, and the other end of the first pressure plate 230 is a free end. The distance between the free end 231 of the first pressure plate 230 and the bottom wall 221 of the receiving space 220 is greater than the distance between the free end 241 of the second pressure plate 240 and the bottom wall 221 of the receiving space 220. This ensures that after the thermistor 300 is installed in the mounting bracket 10, the pressure applied to the thermistor 300 by the first pressure plate 230 and the second pressure plate 240 is uniform, guaranteeing the stability of the thermistor 300 installation.
[0058] Preferably, the line connecting the end of the first pressure plate 230 near the surface and the end of the second pressure plate 240 near the surface is parallel to the axial direction of the first region 111, so that the pressure applied by the first pressure plate 230 and the second pressure plate 240 to the thermistor 300 is more uniform.
[0059] In some embodiments, such as Figure 4 and Figure 5 As shown, the end of the heat-conducting base 100 away from the second region 112 has a clearance notch 120. After the first segment 310 of the thermistor 300 is inserted into the groove 110, the clearance notch 120 can avoid the insulating sleeve 330 on the second segment, so that the first region 111 does not need to be tilted at a large angle. This prevents the difference between the distance between one end of the groove 110 and the compressor 400 in the axial direction and the distance between the other end and the compressor 400 from being too large, thus ensuring that the thermistor 300 is heated evenly.
[0060] Optionally, the distance between the inner wall surface 121 of the clearance notch 120 and the first region 111 is 0mm to 3mm. That is, the distance between the inner wall surface 121 of the clearance notch 120 and the first region 111 is, but is not limited to, 0mm (the inner wall surface 121 of the clearance notch 120 is tangent to the edge of the first region 111), 1mm, 2mm or 3mm.
[0061] In some embodiments, the thickness of the thermally conductive base 100 is 0.8 mm to 1.5 mm. That is, the thickness of the thermally conductive base 100 includes, but is not limited to, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm. This not only ensures that the thickness of the thermally conductive base 100 is large enough to allow the first region 111 of the groove 110 to be inclined, but also avoids excessive heat loss during heat conduction on the thermally conductive base 100 due to excessive thickness, thus ensuring the accuracy of the thermistor 300.
[0062] In other embodiments, such as Figure 6 As shown, a groove 110 is disposed on one side of the surface of the heat-conducting base 100. The wall of the groove 110 includes a third region 113 and a fourth region 114. The third region 113 is a cylindrical surface, and the fourth region 114 is a planar surface. The fourth region 114 is connected to one end of the third region 113 along its axial direction, and the other end of the third region 113 passes through the end face of the heat-conducting base 100 away from the fourth region 114. The axial direction of the third region is parallel to the surface. That is, when the thermistor 300 is installed in the groove 110, the first segment 310 is in contact with the third region 113 and the fourth region 114, and the second segment extends from the end of the heat-conducting base 100 away from the fourth region 114 to avoid the insulating sleeve 330 on the second segment interfering with the contact between the first segment 310 and the groove 110.
[0063] In some embodiments, the mounting bracket 10 of this utility model further includes two mounting plates 140. The two mounting plates 140 are respectively connected to both sides of the heat-conducting base 100, and are used to fix to the end cover 410 of the compressor 400. Each mounting plate 140 is provided with a connecting structure, such as a through hole for threaded parts or a recess for welding. The surface of each mounting plate 140 near the end cover 410 of the compressor 400 is farther from the end cover 410 of the compressor 400 relative to the second surface 132, thereby ensuring that the second surface 132 can tightly adhere to the end cover 410 of the compressor 400, ensuring the heat conduction effect of the heat-conducting base 100.
[0064] In this embodiment of the air conditioner 20, the thermistor 300 is mounted on the end cover 410 of the compressor 400 via the mounting bracket 10 as described in any of the above embodiments. The heat-conducting base 100 of the mounting bracket 10 in this embodiment of the air conditioner 20 is made of a heat-conducting material, allowing the heat from the compressor 400 to be normally conducted to the thermistor 300 through the heat-conducting base 100. Furthermore, the heat-conducting base 100 is provided with a groove 110 that partially conforms to the outer surface of the thermistor 300. This significantly increases the contact area between the thermistor 300 and the heat-conducting base 100, thereby improving the heat conduction effect between the thermistor 300 and the heat-conducting base 100, and thus improving the detection accuracy of the thermistor 300.
[0065] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
