Abstract
Description
Technical Field
[0001] The present application relates to the field of temperature measurement technology, for example, to a mounting bracket and a refrigeration device for a temperature measurement sensor. Background Art
[0002] Freezers and refrigerators are currently commonly used food storage and preservation equipment. Their working principle is to form a low-temperature environment inside the cabinet, so as to use the low-temperature environment to extend the preservation time of foods such as meat, eggs and milk. Among them, the refrigeration system is the core of this type of refrigeration equipment. Taking an air-cooled refrigerator as an example, the refrigeration system mainly includes components such as a compressor and an evaporator. The compressor is set in the compressor cabin at the bottom of the box, and the evaporator is set in the air duct at the back of the box, and can continuously transport cold air to the compartments of the box through the air duct.
[0003] At the same time, the refrigerator's cold storage compartment generally has a variable temperature adjustment function, and users can adjust the temperature within the range of 0℃ to 5℃ as needed. Accordingly, after the user changes the cold storage temperature, the refrigeration system can change the evaporation temperature of the evaporator by changing parameters such as the compressor operating frequency, thereby changing the temperature of the cold air sent into the cold storage compartment. Generally speaking, a temperature sensor (temperature sensor) is set on the evaporator to detect the evaporation temperature in real time. The refrigeration system can determine whether the temperature has been adjusted in place by detecting the real-time temperature.
[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:
[0005] Some temperature sensors in related technologies use temperature sensing tubes, which are attached to the evaporator to detect temperature. However, in actual applications, it is found that the vibration generated by the operation of the compressor will be transmitted to the refrigerator body, which may cause the temperature sensing tube to separate or misalign with the evaporator, thereby affecting the temperature measurement accuracy of the temperature sensor.
[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0062] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0063] The present application discloses a mounting bracket 100, which can be used for the installation and coordination of a temperature measuring sensor and a temperature measuring object, and enables the temperature measuring sensor to be relatively stably arranged at a predetermined temperature measuring position of the temperature measuring object without position deviation, thereby improving the temperature measuring effect of the temperature measuring sensor. Optionally, the temperature measuring object in the embodiment of the present disclosure includes components that play a heat exchange role, such as an evaporator and a condenser, used in a refrigeration device 400, and the types of the refrigeration device 400 include but are not limited to refrigerators, freezers, air conditioners, etc.
[0064] Combination Figures 1 to 8 As shown, the embodiment of the present disclosure provides a mounting bracket 100 for a temperature sensor, which at least includes a frame 110, a first limiting baffle 120 and a second limiting baffle 130. The frame 110 is used as a base for carrying the temperature sensor and the heat exchange tube of the heat exchanger 410. The temperature sensor and at least part of the pipe section of the heat exchange tube are assembled on the frame 110, and the temperature sensor is in contact with the part of the pipe section of the heat exchange tube, thereby realizing the temperature detection function. The first limiting baffle 120 is used to limit and fix the end of the temperature sensor, and can limit its lateral range of movement. The second limiting baffle 130 is used to limit and fix the part of the temperature sensor other than the above-mentioned end, and can make the temperature sensor close to the heat exchange tube, so that the two can quickly transfer heat in the form of "heat conduction", thereby improving the accuracy of the temperature sensor.
[0065] The mounting bracket 100 provided in the embodiment of the present disclosure limits and fixes the end of the temperature sensor and the part fitting with the heat exchange tube respectively by means of the first limit baffle 120 and the second limit baffle 130 arranged at different positions of the frame 110, thereby limiting the movement range of the temperature sensor and making it fit tightly with the heat exchange tube, thereby effectively reducing the misalignment problem caused by factors such as vibration, improving the tightness of the fit between the sensor and the heat exchange tube, and ensuring the working accuracy of the temperature sensor.
[0066] In some optional embodiments, the temperature sensor used in the mounting bracket 100 includes a temperature sensing tube 210 and a temperature measuring probe (not shown) built into the temperature sensing tube 210. The temperature sensing tube 210 can transfer the heat from the heat exchange tube of the heat exchanger 410 to the temperature measuring probe, and then use the temperature measuring probe to detect the real-time heat exchange temperature of the heat exchange tube.
[0067] In this embodiment, if Figure 5 As shown, the overall outer contour of the temperature sensing tube 210 is a long tube. The interior of the tube body of the temperature sensing tube 210 is a hollow structure, and the hollow space can be used as a space for accommodating a temperature measuring probe and / or a temperature sensing medium.
[0068] Optionally, for the former arrangement (only the temperature measuring probe is accommodated in the temperature sensing tube 210), the temperature measuring probe is built into the internal space of the temperature sensing tube 210, and the temperature measuring probe is in close contact with part of the inner tube wall of the temperature sensing tube 210 or forms a gap fit. In this way, the temperature sensing tube 210 can continue to conduct the heat transferred from the heat exchange tube to the temperature measuring probe through the inner tube wall (contact heat conduction) or the gap (air heat conduction), so as to realize the temperature detection function of the temperature measuring probe.
[0069] As for the latter arrangement (temperature probe and temperature sensing medium are placed in the temperature sensing tube 210), the internal space of the temperature sensing tube 210 is filled with the temperature sensing medium, and the temperature sensing probe can be covered by the temperature sensing medium after being inserted into the temperature sensing tube 210. In this form, since the temperature sensing medium fills the entire internal space of the temperature sensing tube, the heat of each section of the temperature sensing tube 210 can be transferred to the inside through the temperature sensing medium, so that the temperature of the temperature sensing tube 210 is more balanced, and the temperature detected by the temperature sensing probe can more accurately reflect the overall temperature of the temperature sensing tube 210, reducing the detection distortion caused by local overheating / overcooling of the temperature sensing tube 210.
[0070] Optionally, the temperature sensing medium is a liquid or gaseous medium type, which has good thermal conductivity to ensure the heat conduction rate between the temperature sensing tube 210 and the temperature measuring probe, thereby improving the sensitivity of temperature detection. Optionally, the type of liquid temperature sensing medium includes but is not limited to: methanol, xylene, glycerin or acetone, etc.
[0071] Alternatively, the temperature sensing tube 210 is made of a material with high thermal conductivity, such as a metal or alloy material. In an embodiment, the types of the above materials include but are not limited to: stainless steel, copper, titanium, tantalum-niobium alloy, and the like.
[0072] In some other optional embodiments, the temperature measuring probe is constructed as a thin rod-shaped structure, which can extend from one longitudinal end of the temperature sensing tube 210 into the temperature sensing tube 210 and be fixed to the temperature sensing tube 210. Here, the temperature sensing tube 210 can not only play a role in heat conduction, but also serve as a shell to protect the temperature measuring probe, so as to prevent the temperature measuring probe from being damaged by other surrounding structural parts, thereby extending the service life of the temperature measuring probe.
[0073] Optionally, the tube body of the temperature sensing tube 210 is formed with a second limiting pressure profile 212, such as Figure 5a The second limit pressure profile 212 is used to limit the depth of the temperature probe extending into the temperature sensing tube 210 .
[0074] The second limiting pressure profile 212 narrows the internal space channel of the temperature sensing tube 210, so that when the temperature measuring probe is extended to the position of the second limiting pressure profile 212, it is stopped, thereby preventing the temperature measuring probe from continuing to extend along the axial direction of the temperature sensing tube 210. Exemplarily, the second limiting pressure profile 212 is formed by squeezing a part of the tube body of the temperature sensing tube 210 and deforming the part of the tube body to partially sink inward and partially convex outward.
[0075] Combination Figure 1 , Figure 2 and Figure 3 As shown, the frame 110 of the mounting bracket 100 is constructed as a longitudinally extending strip-like structure, so that the temperature sensing tube 210 can be assembled in a form consistent with the overall longitudinal direction of the frame 110, and the longitudinal side wall of the temperature sensing tube 210 is attached to the corresponding side of the frame 110. Here, the frame 110 can also play a protective effect on the temperature sensing tube 210 to a certain extent.
[0076] Figure 3 The front view of the mounting bracket 100 frame 110 is shown, and it can be seen from the figure that the frame 110 is provided with a plurality of through holes 111 for the heat exchange tubes to pass through and fix along its longitudinal intervals, and the heat exchange tubes of the heat exchanger 410 are fixed to the mounting bracket 100 through the through holes 111. Here, the through holes 111 are formed through the frame 110 in the thickness direction.
[0077] exist Figure 6a and 6b In the illustrated embodiment, the heat exchange tubes of the heat exchanger 410 are arranged in a serpentine shape, and include a plurality of straight tube sections parallel to each other and a U-shaped tube section for connecting the ends of two adjacent straight tube sections. Optionally, the perforation 111 in this embodiment is used to fix the U-shaped tube section, and thus, the perforation 111 is constructed as a long strip hole that matches the cross-sectional size of the U-shaped tube section, so that the U-shaped tube section 411 can be inserted into the long strip hole as a whole. Here, the inner periphery of the perforation 111 is in contact with the tube section of the U-shaped tube section 411 adjacent to the U-shaped opening.
[0078] Optionally, the heat exchange tube of the heat exchanger 410 is a circular tube, and the cross-sections of the straight tube section and the U-shaped tube section are also circular. In order to improve the tightness of the fitting between the long strip hole and the heat exchange tube, the inner circumference of the hole of the corresponding U-shaped tube section of the long strip hole in the above embodiment is constructed as an arc shape, and the curvature of the arc shape is the same as the outer circumferential curvature of the U-shaped tube section, so that the inner circumference of the part of the long strip hole can fit the heat exchange tube circumferentially.
[0079] Alternatively, the through hole 111 is configured as a circular hole that can accommodate a single U-shaped tube end of the U-shaped tube segment, and the inner diameter of the circular hole is slightly larger than the outer diameter of the U-shaped tube end, so that each U-shaped tube end is correspondingly penetrated in the through hole 111. In this way, each U-shaped tube segment corresponds to a group of through holes 111, and the number of each group of through holes 111 is 2.
[0080] In addition, since the overall thickness of the frame 110 is relatively thin and the inner periphery of the through hole 111 is relatively sharp, the pressure at the contact part between the through hole 111 and the heat exchange tube is too high, thereby causing wear on the heat exchange tube. In view of the above situation, in some optional embodiments, at least part of the inner periphery of the through hole 111 is formed with an outer extension 112 extending outward along the penetration direction of the through hole 111, such as Figure 4 As shown, the outer edge 112 can extend the length of the through hole 111 in its penetration direction, thereby increasing the actual contact area between the inner periphery of the through hole 111 and the heat exchange tube, thereby achieving the beneficial effect of dispersing force and reducing wear.
[0081] Here, the inner periphery formed with the outer extension 112 at least includes the portion where the perforation 111 is in direct contact with the heat exchange tube. Figure 4 In the embodiment, the outer extension edges 112 are located at the two longitudinal ends of the long strip hole, so as to reduce the pressure effect of the long strip hole on the U-shaped pipe section.
[0082] Optionally, the outer edge 112 is formed by extending along a first direction parallel to the penetration direction of the through hole 111; or, the outer edge 112 is formed by extending along a second direction parallel to the penetration direction of the through hole 111; or, the outer edge 112 is formed by extending in a first direction and a second direction respectively parallel to the penetration direction of the through hole 111. Here, the first direction and the second direction are two opposite directions, for example, the first direction corresponds to the left direction of the thickness of the frame 110, and the second direction corresponds to the right direction of the thickness of the frame 110.
[0083] In an embodiment, the number of through holes 111 provided in the frame 110 may be determined according to the number of U-shaped pipe sections on the same side of the heat exchanger 410. The number of through holes 111 provided in the frame 110 may be sufficient to accommodate a part or all of the U-shaped pipe sections.
[0084] In some optional embodiments, the first limiting baffle 120 is disposed at a first longitudinal end position of the frame 110 , and can be used to limit and fix the corresponding tube end of the temperature sensing tube 210 .
[0085] Combination Figure 1 and Figure 1aAs shown, the first limit stopper 120 is protruded on the frame 110. In the embodiment, the temperature sensing tube 210 is mainly used to detect the temperature of the heat exchange tube close to the main body of the heat exchanger 410, so the temperature sensing tube 210 needs to be assembled on the side surface of the frame 110 facing the main body of the heat exchanger 410, so that the first limit stopper 120 is protruded toward one side of the main body of the heat exchanger 410, and the sheet of the first limit stopper 120 is perpendicular to the side of the frame 110.
[0086] Furthermore, the first limiting baffle 120 is provided with a first limiting hole 121 for the pipe section of the temperature sensing tube 210 to pass through. The first limiting hole 121 is used to circumferentially limit the pipe section of the temperature sensing tube 210 to reduce the deviation of the temperature sensing tube 210 toward the outer peripheral side.
[0087] Optionally, the first limiting hole 121 is a closed hole, which is formed through the thickness direction of the first limiting blocking piece 120 .
[0088] Here, the hole type of the first limiting hole 121 includes but is not limited to a circular hole, a square hole, a diamond hole, a triangular hole, etc. Among them, the inner diameter of the circular first limiting hole 121 is slightly larger than the outer diameter of the temperature sensing tube 210, so that the temperature sensing tube 210 can be inserted into the first limiting hole 121 relatively smoothly; or, for a non-circular hole form such as a square hole, the diameter of the inscribed circle of the non-circular hole needs to be slightly larger than the outer diameter of the temperature sensing tube 210, so as to ensure that the temperature sensing tube 210 can be inserted into the first limiting hole 121 as a whole.
[0089] Alternatively, the first limiting hole 121 is configured as a gourd-shaped hole. Here, the gourd-shaped hole includes a plurality of sub-holes, and adjacent sub-holes are connected via a contraction section.
[0090] In some embodiments, the apertures of the plurality of sub-holes are the same and the plurality of sub-holes are arranged in sequence along the protruding direction of the first limit stopper 120. In this way, the temperature sensing tube 210 can be selectively inserted into any of the sub-holes according to assembly requirements, so as to change the assembly spacing between the temperature sensing tube 210 and the frame 110 by assembling the temperature sensing tube 210 with different sub-holes.
[0091] In some other embodiments, the apertures of the plurality of sub-holes are different. Here, the sub-holes with different apertures can be used to assemble temperature sensing tubes 210 with different outer diameters, so that a single mounting bracket 100 can be adapted to the assembly needs of a variety of different temperature sensing tubes 210, thereby improving the universality and versatility of the mounting bracket 100.
[0092] Alternatively, the first limiting hole 121 is a non-enclosed hole, which includes a hole portion and a slot portion. Here, the hole portion of the first limiting hole 121 is formed through the thickness direction of the first limiting baffle 120, and the slot portion is formed by extending from the outer periphery of the first limiting baffle 120 to the hole portion. Here, the slot portion can be used as a path for the temperature sensing tube 210 to be assembled in the hole portion in a push-in manner, and the minimum slot width of the slot portion is slightly smaller than the outer diameter of the temperature sensing tube 210, so as to play a stopper role in limiting the separation of the temperature sensing tube 210.
[0093] Optionally, the first limit stopper 120 is formed by bending a portion of the plate surface of the frame body 110, thereby effectively reducing the overall consumables of the mounting bracket 100. The plate surface position corresponding to the first limit stopper 120 is formed as a first notch 122, such as Figure 1a As shown, the first notch 122 can enhance the structural strength of the frame 110 .
[0094] Alternatively, the first limiting blocking piece 120 is a separate piece independent of the frame body 110 , and is fixed to the first longitudinal end position of the frame body 110 by welding or other methods.
[0095] In some embodiments, the second stopper 130 is disposed at a position of the frame 110 away from the first stopper, so as to limit the main body portion of the temperature sensing tube 210. The second stopper 130 is located on the side of the through hole 111, and is used to make the temperature sensing tube 210 close to the heat exchange tube in the through hole 111 to ensure heat conduction between the two.
[0096] In some optional embodiments, the tube end of the temperature sensing tube 210 corresponding to the first limiting hole 121 is formed with a first limiting pressure profile 211, such as Figure 5a As shown; and, the aperture of the first limiting hole 121 of the first limiting baffle 120 is smaller than the outer diameter of the first limiting pressure profile 211, so that the two can form a stop fit in the axial direction of the temperature sensing tube 210.
[0097] When the temperature sensing tube 210 is assembled with the mounting bracket 100, the temperature sensing tube 210 extends upward from the lower part of the first limit baffle 120 into the first limit hole 121, and forms a stop fit with the first limit hole 121 when extending to the position of the first limit pressure profile 211. The stop fit can prevent the temperature sensing tube 210 from continuing to move upward, thereby limiting the axial extension length of the temperature sensing tube 210.
[0098] Optionally, the first limiting pressure profile 211 is formed by squeezing a portion of the tube body of the temperature sensing tube 210 and causing the portion of the tube body to partially sink inward and partially bulge outward.
[0099] Combination Figure 2aAs shown, the second stopper 130 is an elongated sheet structure as a whole, and the length direction of the second stopper 130 is consistent with the longitudinal direction of the frame 110, and it is formed by protruding perpendicular to the side of the frame 110. Here, the second stopper 130 is located on the same side as the first stopper 120, that is, the side close to the main body of the heat exchanger 410.
[0100] Here, the gap between the second limit baffle 130 and the perforation 111 serves as a space for accommodating the temperature sensing tube 210, wherein the spacing between the second limit baffle 130 and the perforation 111 is equal to the tube diameter of the temperature sensing tube 210, so that the temperature sensing tube 210 placed in the gap space can be in contact with the outer surface of the heat exchange tube in the perforation 111.
[0101] Optionally, similar to the first limit stopper 120, the second limit stopper 130 is formed by bending a portion of the plate surface of the frame 110, thereby also reducing the amount of consumables for installing the bracket 100. Alternatively, the second limit stopper 130 is a separate sheet body independent of the frame 110, and is fixed to the frame 110 by welding or other methods.
[0102] In some further optional embodiments, the mounting bracket 100 further includes a fixing pressing plate 140 , which can be used to limit and fix the tube body portion of the temperature sensing tube 210 away from the first limiting baffle 120 and the second limiting baffle 130 .
[0103] like Figure 1b As shown, the fixed pressing plate 140 is disposed at the second longitudinal end of the frame 110, and it can be bent toward the direction of the through hole 111. Optionally, the fixed pressing plate 140 is bent in a straight line, that is, the fixed pressing plate 140 forms an acute angle with the surface of the frame 110 after bending; another option is that the fixed pressing plate 140 is bent in an arc shape. By bending the fixed pressing plate 140 toward the through hole 111, the temperature sensing tube 210 can be pressed against the frame 110 or the heat exchange tube, thereby improving the tightness of the temperature sensing tube 210 and the frame 110 / heat exchange tube, thereby ensuring the temperature measurement effect of the temperature sensing tube 210.
[0104] Optionally, similar to the first limiting baffle 120, the fixed pressing piece 140 is also formed by bending a portion of the plate surface of the frame body 110, thereby also reducing the amount of consumables for installing the bracket 100. Similarly, the plate surface position corresponding to the fixed pressing piece 140 is formed as a second notch 141, such as Figure 1b As shown, the second notch 141 can also play a role in enhancing the structural strength of the frame 110 .
[0105] In some optional embodiments, the frame 110 , the first limiting blocking piece 120 , the second limiting blocking piece 130 and the fixing pressing piece 140 are an integrally formed structure.
[0106] In some alternative embodiments, Figure 1b As shown, the mounting bracket 100 also includes a wiring slot 150, which can be used for the wiring harness of the temperature sensor to pass through and access the interior of the temperature sensing tube 210. Here, the wiring harness is a temperature probe accessed inside the temperature sensing tube 210 to ensure the normal transmission of the detection electrical signal.
[0107] Combination Figure 1b As shown, the wiring slot 150 is opened at the second longitudinal end position of the frame body 110. Optionally, the wiring slot 150 is rectangular or circular in shape.
[0108] In some other embodiments, the present application further provides a refrigeration device 400, including a device body, a temperature sensor and a mounting bracket 100. The mounting bracket 100 is any of the mounting brackets 100 shown in the previous embodiments, and the temperature sensor is fixed to the device body through the mounting bracket 100 and is used to detect the temperature of the device body.
[0109] For example, the types of the refrigeration equipment 400 include but are not limited to refrigerators, freezers, and air conditioners. Figure 8 The type of refrigeration device 400 shown is a refrigerator.
[0110] Specifically, a heat exchanger 410 is disposed inside the device body, and the types of the heat exchanger 410 include but are not limited to an evaporator, a condenser, etc. Here, the heat exchanger 410 of the device body is used as the temperature measurement object of the temperature measurement sensor, such as Figure 6a and Figure 6b The temperature sensor shown is installed on the evaporator of the equipment body. The evaporator has a plurality of heat exchange tubes, and the plurality of heat exchange tubes are correspondingly arranged in the through holes 111 of the mounting bracket 100; and one end of the temperature sensing tube 210 of the temperature sensor is fixed on the first limit stopper 120 of the mounting bracket 100, and the middle part is fixed in the gap space between the second limit stopper 130 of the mounting bracket 100 and the heat exchange tube, and the other end of the temperature sensing tube 210 is pressed against the heat exchange tube by the fixing pressing plate 140.
[0111] In some optional embodiments, an air duct and a storage compartment are also constructed in the device body. The air duct can connect the evaporator and the storage compartment to continuously transport the low-temperature cold air around the evaporator to the storage compartment, so that the storage compartment can maintain a low-temperature storage environment for a long time. The evaporator (heat exchanger 410) in the present application is arranged in the air duct, and a fan is also provided in the air duct, which is used to drive the cold air from the evaporator to the storage compartment.
[0112] In this embodiment, the fan type arranged in the air duct is a centrifugal fan. Figure 7 The air velocity simulation test data inside the air duct is shown. Figure 7It can be seen that the air velocity in the air duct near the volute air outlet of the centrifugal fan is higher, and the air velocity in the air duct far from the volute air outlet is lower. In order to improve the temperature measurement accuracy of the temperature sensor for the heat exchanger 410 and reduce the adverse effect of wind speed on temperature measurement, the temperature sensor is arranged at the position of the heat exchanger 410 corresponding to the low wind speed area in the air duct in this embodiment. Specifically, the temperature sensor is arranged on the left side of the heat exchanger 410, such as Figure 7 As shown, the air flow rate here is low, and the temperature sensor is less affected by the interference of the air flow rate.
