Description

Technical Field

[0001] This invention relates to the field of sensor technology, and more specifically to a freeze-proof sensor holder. Background Technology

[0002] Existing air conditioner heat exchangers include refrigerant pipes and multiple heat dissipation fins arranged axially along the refrigerant pipes. To detect the ambient temperature around the air conditioner, an ambient temperature sensor is usually installed on the heat exchanger. In current temperature sensor mounting bracket designs, to facilitate fixing the temperature sensor mounting bracket to the refrigerant pipes, the axis of the mounting pipe on the bracket is generally set parallel to the axis of the refrigerant pipes. However, because frost does not easily melt completely when the air conditioner is heating, the condensate formed on the heat dissipation fins is blocked by the temperature sensor mounting bracket and cannot flow down the heat dissipation fins. When the next heating cycle begins, the condensate on the temperature sensor mounting bracket freezes, eventually causing the entire ambient temperature sensor and its mounting bracket to be encased in ice. Summary of the Invention

[0030] The present invention will be further described in conjunction with the following embodiments.

[0031] Depend on Figures 1 to 5As can be seen, the antifreeze sensor bracket described in this embodiment includes a mounting base 2; the mounting base 2 is provided with a mounting tube 21; the mounting tube 21 is provided with a mounting cavity; one end of the mounting base 2 is provided with a first clamping plate 61; the other end of the mounting base 2 is provided with a clamping assembly; the first clamping plate 61 and the clamping assembly are used to clamp the refrigerant pipe 11.

[0032] After the first clamping plate 61 and the clamping assembly clamp the refrigerant pipe 11 respectively, the axial direction of the mounting pipe 21 is inclined relative to the axial direction of the refrigerant pipe 11.

[0033] Specifically, in this embodiment, the sensor mounting bracket is used by first installing the sensor in the mounting cavity of the mounting tube 21, and then clamping it onto the refrigerant pipe 11 by the first clamping plate 61 and the clamping assembly. After the first clamping plate 61 and the clamping assembly are clamped onto the refrigerant pipe 11, the axial direction of the mounting tube 21 is inclined downward relative to the axial direction of the refrigerant pipe 11, so that the condensate formed by the heat dissipation fins 12 or outdoor rainwater can flow down quickly along the outer wall of the mounting tube 21, effectively preventing condensate from accumulating on the surface of the mounting tube 21. Secondly, the mounting tube 21 can be set in the shape of a frustum, which can enhance the inclination between the top surface of the mounting tube 21 and the axial direction of the refrigerant pipe 11, further preventing condensate from accumulating on the surface of the mounting tube 21.

[0034] The antifreeze sensor bracket described in this embodiment includes a clamping assembly comprising a first assembly plate 3 disposed at the other end of the mounting base 2; a second clamping plate 62 disposed on the side of the first assembly plate 3 away from the mounting base 2; the first clamping plate 61 and the second clamping plate 62 cooperate to clamp the refrigerant pipe 11.

[0035] Specifically, in this embodiment, the first clamping plate 61 and the second clamping plate 62 are used to clamp the refrigerant pipe 11 together, making the overall structure stable and reliable.

[0036] In this embodiment, an antifreeze sensor bracket is provided, wherein the mounting tube 21 is disposed on the first assembly plate 3; the axial direction of the mounting tube 21 is perpendicular to the plane on which the first assembly plate 3 is located; and a first tilt angle α1 is provided between the plane on which the first clamping plate 61 is located and the plane on which the first assembly plate 3 is located.

[0037] Specifically, in this embodiment, through the above-described settings, during installation, since the plane where the first clamping plate 61 is located needs to be perpendicular to the axial direction of the refrigerant pipe 11, and there is a first tilt angle a1 between the plane where the first clamping plate 61 is located and the plane where the first assembly plate 3 is located, the plane where the first assembly plate 3 is located cannot be perpendicular to the axial direction of the refrigerant pipe 11. In addition, since the axial direction of the mounting pipe 21 is perpendicular to the plane where the first assembly plate 3 is located, through the above-described settings, the axial direction of the mounting pipe 21 can be tilted relative to the axial direction of the refrigerant pipe 11, and the tilt angle is the same as the first tilt angle a1.

[0038] In this embodiment, a freeze-proof sensor bracket is provided with a second assembly plate 4 between the first assembly plate 3 and the second clamping plate 62; one end of the first assembly plate 3 is connected to the other end of the mounting base 2; a flexible plate 7 is provided between the other end of the first assembly plate 3 and one end of the second assembly plate 4; after the second assembly plate 4 is flipped through the flexible plate 7, the plane on which the second assembly plate 4 is located is parallel to the plane on which the first assembly plate 3 is located; a baffle plate 5 is provided between the other end of the second assembly plate 4 and the second clamping plate 62; the baffle plate 5 is used to abut against the heat dissipation fins 12.

[0039] Specifically, in this embodiment, by setting a first assembly plate 3, a flexible plate 7, and a second assembly plate 4, the second assembly plate 4 can be flipped at the flexible plate 7, thereby cooperating with the first assembly plate 3 to fix the sensor in the mounting cavity.

[0040] In addition, after the second assembly plate 4 is flipped over, the baffle plate 5 abuts against the heat dissipation fins 12, thereby effectively preventing the first clamping plate 61 and the second clamping plate 62 from rotating around the refrigerant pipe 11.

[0041] In this embodiment of the antifreeze sensor bracket, the plane of the baffle plate 5 is perpendicular to the plane of the first assembly plate 3, while the plane of the second assembly plate 4 is parallel to the plane of the first assembly plate 3, such that the plane of the baffle plate 5 is perpendicular to the plane of the second assembly plate 4; a second tilt angle α2 is provided between the plane of the second clamping plate 62 and the plane of the second assembly plate 4. In this embodiment of the antifreeze sensor bracket, both the first tilt angle α1 and the second tilt angle α2 are 1-10 degrees. At this angle, condensate formed on the heat dissipation fins 12 or outdoor rainwater can flow down quickly along the outer wall of the mounting pipe 21; at the same time, at this angle, the antifreeze sensor bracket can also be stably installed on the refrigerant pipe 11.

[0042] In addition, when the angle is greater than 10 degrees, the height difference between the first clamping plate 61 and the second clamping plate 62 will become larger. If the height difference is too large, they cannot be clamped onto the same refrigerant pipe 11. When the angle is less than 1 degree, the height difference will be too small, and an effective tilt cannot be formed.

[0043] Specifically, in this embodiment, a second tilt angle a2 is provided between the plane where the second clamping plate 62 is located and the plane where the second assembly plate 4 is located, and the first tilt angle a1 and the second tilt angle a2 are the same. Since the plane where the second assembly plate 4 is located is parallel to the plane where the first assembly plate 3 is located, the first tilt angle a1 and the second tilt angle a2 are the same. This allows the plane where the first clamping plate 61 is located to be parallel to the plane where the second clamping plate 62 is located, so that the first clamping plate 61 and the second clamping plate 62 can be stably fixed on the refrigerant pipe 11.

[0044] The antifreeze sensor bracket described in this embodiment has a first clamping plate 61 with a first clamping groove 63; a second clamping plate 62 with a second clamping groove 64; the first clamping groove 63 abuts against the top of the refrigerant pipe 11; and the second clamping groove 64 abuts against the bottom of the refrigerant pipe 11.

[0045] Specifically, when a first tilt angle a1 is formed between the plane of the first clamping plate 61 and the plane of the first assembly plate 3, and a second tilt angle a2 is formed between the plane of the second clamping plate 62 and the plane of the second assembly plate 4, the entire antifreeze sensor bracket is tilted. After the second assembly plate 4 is flipped, the height of the second clamping groove 64 is higher than that of the first clamping groove 63, so that the first clamping groove 63 abuts against the top of the refrigerant pipe 11; the second clamping groove 64 abuts against the bottom of the refrigerant pipe 11. Through the above-mentioned clamping method with height difference, compared with the traditional horizontal snap clamping method, the sensor bracket can be clamped on the refrigerant pipe 11 more effectively.

[0046] The antifreeze sensor bracket described in this embodiment has an inclined slope 24 between the top of the mounting tube 21 and the mounting base 2. This design accelerates the flow of condensate and prevents rainwater from accumulating at the joints between the surfaces.

[0047] In this embodiment, an antifreeze sensor bracket is provided. The first assembly plate 3 has a through mounting hole 31 communicating with one end of the mounting cavity. A mounting assembly for fixing the sensor is provided between the first assembly plate 3 and the second assembly plate 4. The mounting assembly includes a connecting hole 41 through the second assembly plate 4, an elastic connecting strip 42 provided in the connecting hole 41, and a fixing strip 32 provided in the first assembly plate 3. After the second assembly plate 4 is flipped by the flexible plate 7, the connecting hole 41 communicates with the mounting hole 31, and the fixing strip 32 protrudes into the connecting hole 41. The fixing strip 32 and the elastic connecting strip 42 are positioned opposite each other at both ends of the mounting hole 31.

[0048] Specifically, when installing the sensor in the mounting cavity, the sensor is first inserted into the mounting cavity through the mounting hole 31 of the first assembly plate 3. Then, the second assembly plate 4 is flipped at the flexible plate 7 so that the end of the sensor passes through the connecting hole 41 and is clamped between the fixing strip 32 and the elastic connecting strip 42, thereby completing the installation of the sensor.

[0049] The mounting assembly further includes a first fixing hole 33 on the first assembly plate 3 and a second fixing hole 44 on the second assembly plate 4; after the second assembly plate 4 is flipped over by the flexible plate 7, the first fixing hole 33 and the second fixing hole 44 are positioned opposite each other; wherein, a locking block can be provided at the position of the first fixing hole 33 or the second fixing hole 44 to fix the first assembly plate 3 and the second assembly plate 4; or after the first fixing hole 33 and the second fixing hole 44 are positioned opposite each other, the first fixing hole 33 and the second fixing hole 44 can be fixed by fasteners such as screws or cable ties, thereby fixing the first assembly plate 3 and the second assembly plate 4.

[0050] The second assembly plate 4 is provided with a clearance hole 43; the elastic connecting strip 42 is movably disposed between the clearance hole 43 and the connecting hole 41. This arrangement provides sufficient space for the deformation of the elastic connecting strip 42, thus enabling it to accommodate sensors of different sizes.

[0051] The frost-proof sensor bracket described in this embodiment has a vent hole 22 at the other end of the mounting tube 21; a limiting block 23 is provided inside the vent hole 22. By providing the vent hole 22, the air permeability of the mounting tube 21 can be enhanced, improving the accuracy of sensor measurements, and by providing the limiting block 23, the sensor can be prevented from falling out of the vent hole 22.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
