[0001] The utility model relates to the technical field of temperature sensing, in particular to a temperature sensor fixing clamp and heat exchange equipment. Background Art

[0002] In refrigeration or heat exchange equipment such as air conditioners, it's necessary to measure the refrigerant and air temperatures in the heat exchanger pipes. A temperature sensor clamp is typically used to secure the temperature sensor to the heat exchanger pipes. The clamp consists of a first clamp for securing the pipes, and a second clamp for securing the temperature sensor.

[0003] Traditional fixing clamps present several challenges. Manufacturers of air conditioners and other refrigeration or heat exchange equipment must first secure the temperature sensor to the second clamp during production, followed by securing the temperature sensor clamp to the pipeline. This can be cumbersome. Furthermore, the precise fit between the second clamp and the temperature sensor can be difficult to achieve. If the clamp is too tight, the sensor will be difficult to install. If the clamp is too loose, the sensor, while easy to install, can also become loose, making it susceptible to misalignment or even falling during transportation.

[0004] Therefore, it is urgent to solve the installation problem of the temperature sensor and the temperature sensor fixing clip. Utility Model Content

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 As shown, it is a temperature sensor fixing clip 10 according to an embodiment of the present invention, comprising a temperature sensor 130 and a fixing clip body; the fixing clip body comprises a clamping portion 110 and a connecting portion 120 connected in one piece;

[0029] The clamping portion 110 is cylindrical, and a clamping opening 111 is provided on one side of the clamping portion 110. The clamping portion 110 is used to be sleeved on the heat exchange pipe through the clamping opening 111.

[0030] The connecting portion 120 is connected to one side of the clamping portion 110 in the opening direction, and the connecting portion 120 is located on one side of the clamping opening 111 . The connecting portion 120 is fixedly connected to the temperature sensor 130 .

[0031] In the embodiment, the clamping portion 110 and the connecting portion 120 are integrally formed, and the fixing clamp body is made of elastic metal or elastic plastic. For example, the fixing clamp body is made of copper alloy, which has good thermal conductivity and toughness, can well conduct heat, and is clamped on the pipeline. For example, the fixing clamp body is made of aluminum alloy, which has good thermal conductivity and can well conduct heat. For example, the fixing clamp body is made of stainless steel, which has good toughness and elasticity and can be stably clamped on the pipeline. The fixing clamp body can also be made of other elastic metal materials.

[0032] In the embodiment, the clamping portion 110 is provided with a clamping opening, which can make the clamping portion 110 open. Here, the opening refers to making the opening width of the clamping opening 111 on the clamping portion 110 larger. The connecting portion is connected to one side of the opening direction of the clamping portion, which means that the connecting portion is located on one side of the opening direction of the clamping portion. For example, when the clamping portion is cylindrical, the clamping opening is circumferentially provided and extends along the axial direction of the clamping portion, and the opening direction of the clamping portion is the radial direction. For example, when the clamping portion is a triangular prism, the clamping opening is provided in the transverse (radial) direction and extends along the length direction of the clamping portion, and the opening direction of the clamping portion is the transverse direction. Since the connecting portion 120 is located on one side of the clamping opening on the clamping portion 110, the connecting portion 120 can move away from the other side of the clamping opening as the clamping portion 110 opens. When the clamping portion 110 is clamped on the pipeline, the connecting portion 120 can stably abut against the surface of the pipeline with the temperature sensor.

[0033] It is worth mentioning that the cross-sectional shape of the clamping portion 110 can be circular, square, rectangular, triangular, or polygonal, such as hexagonal or octagonal. The cross-sectional shape of the clamping portion matches the shape of the pipeline of the heat exchange device, thereby better fitting the surface of the pipeline and being clamped on the pipeline. For example, when the cross-sectional shape of the pipeline is hexagonal, the cross-sectional shape of the clamping portion 110 is also hexagonal.

[0034] In one embodiment, the clamping portion 110 is provided in a cylindrical shape, and the cylindrical shape of the clamping portion 110 matches the shape of the pipeline of the heat exchange device. The clamping portion 110 is used to clamp on the heat exchange pipeline. The clamping portion 110 is provided with a clamping opening 111 on one side in the axial direction, so that the cross section of the clamping portion 110 is provided in a semicircular or arc shape. Applying force to both sides of the clamping opening 111 can make the clamping portion 110 open, thereby being able to be sleeved on the pipeline. After the clamping opening 111 is loosened, the clamping portion 110 tightly abuts against the pipeline under the elastic action of itself, thereby clamping the fixing clamp body on the pipeline.

[0035] The clamping opening 111 provided on the clamping portion 110 facilitates the opening and clamping of the clamping portion 110 onto the pipeline. In one embodiment, a spacing groove is provided along the circumferential direction of one side edge of the clamping portion 110. Spacing grooves 112 are provided on the clamping portion 110, extending parallel to the radial direction of the clamping portion 110. This allows the multiple clamping sub-sections 114 on the clamping portion 110 to be spaced apart from each other, facilitating the opening of the clamping sub-sections 114.

[0036] In one embodiment, Figure 2 As shown, the clamping portion 110 includes a supporting portion 113 connected to the connecting portion 120 and a plurality of clamping sub-portions 114 connected to the side of the supporting portion 113 away from the connecting portion 120, and a spacing groove 112 is formed between adjacent clamping sub-portions 114. In this way, the supporting portion 113 and the clamping sub-portions 114 are both arranged in an arc shape, and the mutual spacing of the clamping sub-portions 114 is beneficial for the installer to apply force to the clamping sub-portions 114, thereby facilitating the opening of the clamping sub-portions 114.

[0037] In this embodiment, the connecting portion 120 is connected to one side of the circumference of the clamping portion 110, or in other words, the connecting portion 120 is connected to one side of the radial direction of the clamping portion 110. The connecting portion 120 is fixedly connected to the temperature sensor 130. This makes the connection between the connecting portion 120 and the temperature sensor 130 more stable. During production, the manufacturer of the fixing clamp 10 fixes the temperature sensor 130 to the connecting portion 120, eliminating the step of installing the temperature sensor 130 by the heat exchange equipment manufacturer. Alternatively, during production, the temperature sensor manufacturer fixes the connecting portion 120 of the fixing clamp to the temperature sensor, packaging the temperature sensor and the fixing clamp body into a single integrated temperature sensor. For the heat exchange equipment manufacturer, it is only necessary to clamp the clamping portion 110 to the pipeline, without having to adjust the position of the temperature sensor 130, thereby improving the installation efficiency of the heat exchange equipment manufacturer. In addition, the manufacturer of the fixing clamp 10 pre-installs the temperature sensor 130 on the connecting portion 120, making the installation of the temperature sensor 130 more accurate.

[0038] When the clamping portion 110 is clamped on the pipeline, the temperature sensor on the connecting portion 120 is brought into contact with the pipeline, thereby enabling the temperature sensor to detect the temperature of the pipeline.

[0039] In the above embodiment, the temperature sensor fixing clip 10 fixes the temperature sensor 130 on the connecting part 120 when leaving the factory, so that the subsequent heat exchange equipment manufacturer does not need to install the temperature sensor 130, saving the installation process of the heat exchange equipment manufacturer and simplifying its operation steps. In addition, by fixing the temperature sensor 130 to the connecting part 120, the installation is more stable and it is not easy to be dislocated or fall due to vibration during transportation, thereby improving reliability.

[0040] In order to ensure a stable connection between the connecting portion 120 and the temperature sensor 130, in one embodiment, the connecting portion 120 and the temperature sensor 130 are welded. In this embodiment, the connecting portion 120 and the temperature sensor 130 are fixed by welding, which can make the connection between the two more stable.

[0041] In one embodiment, see Figures 1 to 4 The temperature sensor 130 includes a temperature sensor body and a shell 131 . The temperature sensor body is disposed in the shell 131 , and an outer surface of the shell 131 is welded to the connecting portion 120 .

[0042] It is worth mentioning that, in addition to welding, the temperature sensor 130 and the connecting portion 120 may be fixedly connected using other existing fixed connection methods. For example, in one embodiment, the connecting portion 120 and the temperature sensor 130 are fixedly connected by screws. In another embodiment, the connecting portion 120 and the temperature sensor 130 are fixedly connected by rivets. In another embodiment, the connecting portion 120 and the temperature sensor 130 are fixedly connected by adhesive.

[0043] In one embodiment, the temperature sensor 130 includes a temperature sensor body and a housing 131 . The temperature sensor body is disposed in the housing 131 , and the housing 131 and the connecting portion 120 are integrally formed.

[0044] In this embodiment, the housing 131 and the connecting portion 120 of the temperature sensor are made of the same material, that is, the housing 131, the connecting portion 120, and the clamping portion 110 are made of the same material. In one embodiment, the housing 131, the connecting portion 120, and the clamping portion 110 are made of a metal material. The housing 131, the connecting portion 120, and the clamping portion 110 are integrally cast. In one embodiment, the housing 131, the connecting portion 120, and the clamping portion 110 are integrally stamped. In one embodiment, the housing 131, the connecting portion 120, and the clamping portion 110 are integrally milled using a machine tool. In this embodiment, forming the housing 131, the connecting portion 120, and the clamping portion 110 in an integrally molded manner can make the connection between the housing 131 and the connecting portion 120 more stable and further reduce production costs. In this embodiment, after integrally molding the housing 131, the connecting portion 120, and the clamping portion 110, the temperature sensor body is installed in the housing 131, and the housing 131 is sealed to achieve overall assembly.

[0045] In one embodiment, Figure 1 and Figure 2As shown, the connecting portion 120 is arranged in a cylindrical shape, and an installation cavity is formed on the inner side of the connecting portion 120. The temperature sensor 130 is arranged in a cylindrical shape and is arranged in the installation cavity. The inner surface of the connecting portion 120 is attached to the circumferential surface of the temperature sensor 130, and the inner surface of the connecting portion 120 is fixedly connected to the circumferential surface of the temperature sensor 130. A detection port is opened on one side of the connecting portion 120, and the temperature sensor is at least partially exposed to the connecting portion through the detection port 120.

[0046] In this embodiment, the temperature sensor 130 is set to a cylindrical shape, and the connecting part 120 is set to a cylindrical shape that matches the temperature sensor 130, so that the inner surface of the connecting part 120 can better fit the surface of the temperature sensor 130, thereby making the connection between the two more stable.

[0047] In this embodiment, a detection port is opened on one side of the connecting portion 120 along the axial direction, and the detection port extends from one axial end of the connecting portion 120 to the other end. By opening the detection port, the temperature sensor can be exposed, and the temperature sensor can be tightly attached to the surface of the pipeline, thereby improving the accuracy of temperature detection.

[0048] In one embodiment, the connection portion 120 has a detection port on the side facing the clamping portion 110, and the clamping portion 110 has a clamping opening on the side facing the temperature sensor. This allows both the detection port and the clamping opening to face the pipeline. When the clamping portion is clamped onto the pipeline, the temperature sensor adheres to the pipeline, making temperature detection more accurate.

[0049] In other embodiments, the temperature sensor may be configured in other shapes, such as a square, a triangular prism, an ellipse, a wedge, etc., and the connecting portion may be configured in a shape that matches the temperature sensor, such as a square cylinder (i.e., a cylindrical structure with a square or rectangular cross-section), an ellipse cylinder, a plate, etc. A detailed description of each of these is omitted in this embodiment.

[0050] In one embodiment, the length of the temperature sensor 130 is greater than the connecting portion 120. Specifically, the axial length of the temperature sensor 130 is greater than the axial length of the connecting portion 120. This can help increase the contact area between the temperature sensor 130 and the pipeline, thereby improving the measurement accuracy of the temperature sensor 130.

[0051] In one embodiment, Figure 1 and Figure 2As shown, the axial direction of the clamping portion 110 is parallel to the axial direction of the connecting portion 120. In this embodiment, the axial direction of the clamping portion 110 is parallel to the axial direction of the connecting portion 120, and the axial direction of the temperature sensor 130 on the connecting portion 120 is parallel to the axial direction of the clamping portion 110, i.e. the axial direction of the temperature sensor 130 is parallel to the axial direction of the pipeline, which is beneficial for the temperature sensor 130 to be closer to the pipeline and for the temperature monitoring accuracy of the temperature sensor 130 on the pipeline to be higher.

[0052] In order to make the temperature sensor 130 closer to the heat exchange pipeline and make the temperature measurement accuracy of the temperature sensor 130 on the pipeline higher, in one embodiment, the distance between the central axis of the clamping portion 110 and the central axis of the connecting portion 120 is less than the sum of the radius of the clamping portion 110 and the radius of the connecting portion 120.

[0053] In this embodiment, the distance between the central axis of the clamping portion 110 and the central axis of the connecting portion 120 is less than the sum of the radius of the clamping portion 110 and the radius of the connecting portion 120, and since the central axis of the clamping portion 110 coincides with the central axis of the pipeline and the central axis of the connecting portion 120 coincides with the central axis of the temperature sensor 130, it means that the distance between the central axis of the pipeline and the central axis of the temperature sensor 130 is less than the sum of the radius of the clamping portion 110 and the radius of the connecting portion 120, so that the pipeline and the temperature sensor 130 can be more closely fitted under the elastic force of the fixing clamp 10, and the temperature sensor 130 is closer to the heat exchange pipeline, and the temperature measurement accuracy of the temperature sensor 130 on the pipeline is higher.

[0054] In order to adapt to the straight pipe type pipeline, in one embodiment, as shown in Figure 1 and Figure 2 the central axis of the clamping portion 110 is arranged in a straight line.

[0055] In order to adapt to the curved pipe type pipeline, in one embodiment, as shown in Figure 3 and Figure 4 the central axis of the clamping portion 110 is arranged in a curved line.

[0056] In the above embodiments, the shape of the clamping portion 110 can be set according to the shape of the pipeline to be installed. When the pipeline is a straight pipe, the central axis of the clamping portion 110 is arranged in a straight line to better adapt to the straight pipe pipeline and fully fit the surface of the pipeline, so that the fixing clamp 10 is more stable when installed on the pipeline. When the pipeline is a curved pipe, the central axis of the clamping portion 110 is arranged in a curved line to better adapt to the curved pipe pipeline and fully fit the surface of the pipeline, so that the fixing clamp 10 is more stable when installed on the pipeline.

[0057] In one embodiment, as shown in Figure 1 and Figure 2 As shown, there are multiple spacing grooves 112, and each spacing groove 112 is distributed along the axial direction of the clamping portion 110. In this embodiment, the spacing grooves 112 are distributed along the axial direction, so that the multiple clamping sub-parts 114 are distributed in the axial direction, which facilitates the opening of the clamping sub-parts 114.

[0058] In one embodiment, Figure 1 and Figure 2 As shown, the cross-section of the connecting portion 120 is arc-shaped. In this embodiment, the radial cross-section of the connecting portion 120 is semicircular or arc-shaped, which is beneficial to reducing the material of the connecting portion 120 and saving the production cost of the fixing clip.

[0059] In one embodiment, a heat exchange device is provided, comprising the temperature sensor fixing clamp described in any one of the above embodiments.

[0060] In this embodiment, the heat exchange device can be an air conditioner, a refrigerator, a heating device, or other heat exchange device. The heat exchange device is used for heat exchange, so it can achieve both cooling and heating. The heat exchange device has a heat exchanger, which includes a pipeline, and the clamping part is clamped and fixed on the pipeline.

[0061] In this embodiment, the temperature sensor fixing clip fixes the temperature sensor on the connecting part 120 when leaving the factory, so that subsequent heat exchange equipment manufacturers do not need to install the temperature sensor, saving the installation process of the heat exchange equipment manufacturers and simplifying their operating steps. In addition, by fixing the temperature sensor to the connecting part 120, the installation is more stable and is not easy to be dislocated or fall due to vibration during transportation, thereby improving reliability.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
