Description
Technical Field
[0001] The utility model relates to the technical field of compressors, and in particular to a shell component and a compressor. Background Art
[0002] In order to ensure the reliable operation of the compressor, a temperature sensor is usually installed on the compressor casing to monitor the temperature status of the compressor during operation; the compressor casing includes a shell and an upper cover, that is, the temperature sensor is usually installed on the outside of the compressor casing or on the upper cover side.
[0003] Among them, the method of setting the temperature sensing package on the upper cover is relatively convenient to install and fix, but because the temperature sensing package set on the upper cover is far away from the motor in the shell, the response to abnormal conditions caused by excessive temperature rise of the motor is relatively delayed.
[0004] In addition, the temperature sensing packages commonly used at present are mostly cylindrical and are in linear contact with the object being measured. This contact mode results in relatively low test accuracy of the temperature sensing package. Utility Model Content
[0005] The main purpose of the utility model is to provide a shell assembly and a compressor to solve the problem in the prior art that the testing accuracy of the temperature sensing element is relatively low due to the line contact between the temperature sensing element and the casing of the compressor.
[0006] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a shell assembly is provided, which includes a temperature sensing element and a compressor casing, and a recessed portion is concavely provided on the outer wall surface of the casing; the temperature sensing element is arranged in the recessed portion, so that the temperature sensing element monitors the temperature of the compressor during operation; wherein, there is surface contact between the outer wall surface of the temperature sensing element and the recessed surface of the recessed portion.
[0007] Furthermore, the entire recessed surface is in contact with the outer wall surface of the temperature sensing component.
[0008] Furthermore, the concave surface is an arc surface.
[0009] Furthermore, welding spots are arranged on the concave surface, and the welding spots are located at the edges of the concave surface, so as to weld the temperature sensing element and the housing.
[0010] Furthermore, a plurality of welding spots are arranged on the concave surface, and the plurality of welding spots are distributed at intervals along the circumference of the concave surface.
[0011] Furthermore, a first matching portion is provided on the recessed surface, and a second matching portion is provided on the outer wall surface of the temperature sensing component; one of the first matching portion and the second matching portion is a protruding portion, and the other is a groove, and the protruding portion is clamped in the groove.
[0012] Further, the first matching portion is located at the edge of the recessed surface.
[0013] Furthermore, a plurality of first matching parts are arranged on the recessed surface, a plurality of second matching parts are arranged on the outer wall surface of the temperature sensing element, and the plurality of first matching parts and the plurality of second matching parts are arranged one by one; the plurality of first matching parts are distributed at intervals along the circumference of the recessed surface.
[0014] Furthermore, the recessed portion is arranged on the outer peripheral surface of the casing.
[0015] According to another aspect of the present invention, a compressor is provided, which includes the above-mentioned shell assembly.
[0016] By applying the technical solution of the utility model, the shell assembly includes a temperature sensing element and a compressor casing, and a recessed portion is concavely provided on the outer wall surface of the casing; the temperature sensing element is arranged in the recessed portion so that the temperature sensing element can monitor the temperature of the compressor during operation; wherein, there is surface contact between the outer wall surface of the temperature sensing element and the recessed surface of the recessed portion.
[0017] Compared with line contact, surface contact has a larger contact area; the larger the contact area, the more complete the heat exchange between the temperature sensing element and the casing, and the better the temperature measurement effect; therefore, when the temperature sensing element and the casing are in surface contact, the direct contact area between the temperature sensing element and the casing is increased, thereby making the test accuracy of the temperature sensing element relatively high, that is, improving the test accuracy of the temperature sensing element; it can be seen that the shell assembly of the present application solves the problem of relatively low test accuracy of the temperature sensing element in the prior art due to line contact between the temperature sensing element and the casing of the compressor.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.
[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0030] The utility model provides a shell assembly, please refer to Figures 2 to 5 The shell assembly includes a temperature sensing element 20 and a compressor casing 10, and a recessed portion 11 is concavely provided on the outer wall surface of the casing 10; the temperature sensing element 20 is arranged in the recessed portion 11, so that the temperature sensing element 20 monitors the temperature of the compressor during operation; wherein, the outer wall surface of the temperature sensing element 20 and the recessed surface 110 of the recessed portion 11 are in surface contact.
[0031] Compared with line contact, surface contact has a larger contact area; the larger the contact area, the more complete the heat exchange between the temperature sensing element 20 and the casing 10, and the better the temperature measurement effect; therefore, when the temperature sensing element 20 and the casing 10 are in surface contact, the direct contact area between the temperature sensing element 20 and the casing 10 is increased, thereby making the test accuracy of the temperature sensing element 20 relatively high, that is, improving the test accuracy of the temperature sensing element 20; it can be seen that the shell assembly of the present application solves the problem of relatively low test accuracy of the temperature sensing element 2 in the prior art due to the line contact between the temperature sensing element 2 and the casing 1 of the compressor.
[0032] It should be noted that when the compressor is running, at least some of the components in the casing 10 of the compressor generate heat due to the operation, thereby increasing the temperature of the casing 10. For example, the motor disposed in the casing 10 generates heat during operation.
[0033] Specifically, a recessed portion 11 is formed by stamping the outer wall surface of the casing 10 from the outside to the inside by a stamping process, thereby solving the problem of relatively low testing accuracy of the temperature sensing element 2 due to line contact between the temperature sensing element 2 and the casing 1 of the compressor in the prior art without substantially increasing the cost.
[0034] Specifically, the depth of the recessed portion 11 can be adjusted according to the thickness of the housing 10 and the layout of components in the housing 10 .
[0035] Specifically, the outer wall surface of the housing 10 includes an outer peripheral surface and two end surfaces, and the recessed portion 11 is provided on the outer peripheral surface of the housing 10 .
[0036] Specifically, the recessed portion 11 is arranged at a position of the casing 10 that is opposite to a preset space in the casing 10. The preset space in the casing 10 refers to a space in the casing 10 that is located above or below the motor, and there are no components in the preset space. In this way, the embedding of the motor is not affected, and the temperature rise caused by the heating of the motor can be monitored more accurately, thereby avoiding or reducing the problem of relatively delayed response to abnormal conditions caused by excessive temperature rise of the motor.
[0037] In this embodiment, the entire recessed surface 110 of the recessed portion 11 contacts the outer wall of the temperature sensing element 20 , that is, the recessed surface 110 fits closely with the outer wall of the temperature sensing element 20 . At this time, the contact area between the recessed surface 110 and the outer wall of the temperature sensing element 20 is the maximum contact area.
[0038] In this embodiment, the concave surface 110 is an arc surface.
[0039] In this embodiment, welding spots are provided on the recessed surface 110 , and the welding spots are located at the edges of the recessed surface 110 , so that the temperature sensing element 20 and the housing 10 are welded together, thereby fixing the temperature sensing element 20 on the housing 10 .
[0040] Since the welding point will increase the heat transfer loss between the temperature sensing element and the housing, thus affecting the temperature measurement accuracy of the temperature sensing element. For the line contact method in the prior art, the welding point can only be arranged on the contact line, and the welding point has a greater impact on the temperature measurement result; while the housing assembly of the present application sets the welding point at the edge of the recessed surface 110 to greatly reduce the heat transfer loss between the temperature sensing element 20 and the housing 10, thereby greatly reducing the impact of welding on the temperature measurement result of the temperature sensing element 20, which is conducive to ensuring the temperature measurement accuracy of the temperature sensing element 20.
[0041] Optionally, a plurality of welding points are provided on the recessed surface 110, and the plurality of welding points are all located at the edge of the recessed surface 110, and the plurality of welding points are distributed at intervals along the circumference of the recessed surface 110; in this way, the connection stability between the temperature sensing element 20 and the housing 10 can be increased to avoid or reduce the risk of the temperature sensing element 20 falling off the housing 10 when the housing 10 vibrates.
[0042] Furthermore, the plurality of welding points on the concave surface 110 include two welding points respectively disposed at two opposite side edges of the concave surface 110. Figure 5 As shown, the first welding point 31 and the second welding point 32 are two welding points on the recessed surface 110 , and the first welding point 31 and the second welding point 32 are respectively arranged at two opposite side edges of the recessed surface 110 .
[0043] Compared with the arrangement of solder joints in a line contact manner in the prior art, the arrangement of multiple solder joints in the present application can make the connection between the temperature sensing element 20 and the housing 10 more stable.
[0044] In this embodiment, a first matching portion is provided on the recessed surface 110, and a second matching portion is provided on the outer wall surface of the temperature sensing component 20; one of the first matching portion and the second matching portion is a protrusion, and the other is a groove, and the protrusion is clamped in the groove, thereby fixing the temperature sensing component 20 on the housing 10.
[0045] Specifically, the protrusion is a protruding column.
[0046] Specifically, the first matching portion is located at the edge of the recessed surface 110 to avoid or reduce the influence of the setting of the first matching portion on the temperature measurement result of the temperature sensing element 20 , which is conducive to ensuring the temperature measurement accuracy of the temperature sensing element 20 .
[0047] Optionally, a plurality of first matching portions are provided on the recessed surface 110, and a plurality of second matching portions are provided on the outer wall surface of the temperature sensing element 20. The plurality of first matching portions and the plurality of second matching portions are provided in one-to-one correspondence, and each protrusion is clamped in a corresponding groove; the plurality of first matching portions are all located at the edge of the recessed surface 110, and the plurality of first matching portions are distributed at circumferential intervals along the recessed surface 110; in this way, the connection stability between the temperature sensing element 20 and the housing 10 can be increased to avoid or reduce the risk of the temperature sensing element 20 falling off the housing 10 when the housing 10 vibrates.
[0048] In this embodiment, the temperature sensing element 20 includes a temperature sensing body and a sleeve 21 . The temperature sensing body is disposed in the sleeve 21 , and the outer wall surface of the sleeve 21 is the outer wall surface of the temperature sensing element 20 .
[0049] Specifically, the sleeve 21 and the recessed surface 110 are welded; and the second matching portion is disposed on the sleeve 21 .
[0050] Specifically, the outer wall surface of the temperature sensing element 20 includes an outer peripheral surface and two end surfaces. The outer peripheral surface of the temperature sensing element 20 is used to contact the recessed surface 110 , that is, the outer peripheral surface of the sleeve 21 is used to contact the recessed surface 110 .
[0051] Optionally, the outer peripheral surface of the temperature sensing element 20 is a cylindrical surface.
[0052] Specifically, the temperature sensing member 20 includes a temperature sensing package.
[0053] In this embodiment, a bracket 12 is disposed on the outer peripheral wall of the housing 10 .
[0054] In this embodiment, an air inlet 13 communicating with the interior of the housing 10 is disposed on the outer peripheral wall of the housing 10 .
[0055] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:
[0056] In the shell assembly provided by the present invention, the shell assembly includes a temperature sensing component 20 and a compressor casing 10, and a recessed portion 11 is concavely provided on the outer wall surface of the casing 10; the temperature sensing component 20 is arranged in the recessed portion 11, so that the temperature sensing component 20 monitors the temperature of the compressor during operation; wherein, the outer wall surface of the temperature sensing component 20 and the recessed surface 110 of the recessed portion 11 are in surface contact.
[0057] Compared with line contact, surface contact has a larger contact area; the larger the contact area, the more complete the heat exchange between the temperature sensing element 20 and the casing 10, and the better the temperature measurement effect; therefore, when the temperature sensing element 20 and the casing 10 are in surface contact, the direct contact area between the temperature sensing element 20 and the casing 10 is increased, thereby making the test accuracy of the temperature sensing element 20 relatively high, that is, improving the test accuracy of the temperature sensing element 20; it can be seen that the shell assembly of the present application solves the problem of relatively low test accuracy of the temperature sensing element 2 in the prior art due to the line contact between the temperature sensing element 2 and the casing 1 of the compressor.
