Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a temperature sensing bulb mounting structure on a heat exchanger tube. Background Technology

[0002] Temperature sensing bulbs are usually installed on heat exchange tubes by cable ties. This method is not secure, has poor reliability, and is prone to falling off. It can lead to poor contact between the temperature sensing bulb and the heat exchange tube, affecting the detection accuracy. In addition, the temperature sensing probe of the temperature sensing bulb is directly exposed to the outside, making it susceptible to the influence of the return air from the indoor unit, which can also lead to inaccurate measurements and low measurement accuracy. Summary of the Invention

[0003] The problem solved by this invention is that the temperature sensing bulb on the existing heat exchange tube is not securely fixed and is easy to loosen, which affects the detection accuracy. Moreover, the temperature sensing bulb is exposed and is easily affected by the return air of the indoor unit, which leads to inaccurate measurement.

[0004] To address the aforementioned problems, this invention proposes a temperature sensing bulb installation structure, which is installed on the heat exchange tube of a heat exchanger and includes an insulation box through which the heat exchange tube passes. The temperature sensing head of the temperature sensing bulb is located inside the insulation box and contacts the heat exchange tube.

[0005] The temperature sensor mounting structure on the heat exchange tube in this embodiment of the invention places the temperature sensor inside the heat insulation box, thus preventing it from being affected by the return air from the indoor unit and causing inaccurate measurements. Moreover, the temperature sensor is parallel and in line with the heat exchange tube inside the heat insulation box, resulting in a large contact area, which helps to improve measurement accuracy.

[0006] Furthermore, the heat insulation box includes a box body and a box cover that are snapped together. The heat exchange tube and the temperature sensor are respectively located inside the box body and the box cover. When the box body and the box cover are snapped together, the temperature sensor and the heat exchange tube are in contact.

[0007] In this technical solution, by fastening the box body and the box cover together, the temperature sensing head of the temperature sensing bulb can be easily and quickly brought into close contact with the heat exchange tube, making the installation simple, convenient and quick.

[0008] Furthermore, the box body and the box cover are provided with a slot for accommodating the heat exchange tube. When the box body and the box cover are fastened together, the slot on the box body and the box cover clamps the heat exchange tube.

[0009] In this technical solution, the design ensures that the heat insulation box can be firmly clamped onto the heat exchange tube, making it difficult to loosen or detach, and ensuring that the temperature sensing head has a long-lasting and good contact with the heat exchange tube.

[0010] Furthermore, the slot is semi-circular, and its diameter is equal to that of the heat exchange tube.

[0011] In this technical solution, the design ensures that the heat exchange tube and the slot fit tightly, and the return air from the indoor unit will not enter the insulation box through the slot. This avoids the problem of inaccurate measurement and low measurement accuracy caused by the return air from the indoor unit affecting the temperature sensor.

[0012] Furthermore, a sealing strip is provided on the groove wall of the first slot.

[0013] In this technical solution, the sealing strip further enhances the seal at the connection between the heat exchange tube and the slot, ensuring that the return air from the indoor unit will not enter the insulation box and affect the measurement accuracy of the temperature sensor.

[0014] Furthermore, the cover is provided with a wire hole for the wire of the temperature sensor to pass through, and the wire hole is connected to a slot on the cover.

[0015] In this technical solution, the connection between the wire hole and the slot on the cover facilitates quick and easy installation of the temperature sensor, eliminating the hassle of threading the wire through the wire hole.

[0016] Furthermore, the box body is provided with a slot for accommodating the heat exchange tube, and the box cover is provided with a wire hole for the wire of the temperature sensor to pass through. When the box body and the box cover are fastened together, the wire hole is connected to the slot.

[0017] In this technical solution, the heat exchange tube only penetrates the box body. With this design, during the installation process, the heat insulation box can be installed onto the heat exchange tube first, and then the temperature sensor can be installed, making the installation more convenient.

[0018] Furthermore, a pair of baffles are inserted into the wire hole, and the wire is clamped by the pair of baffles. The baffles are in close contact with the wall of the wire hole. When the box body and the box cover are fastened together, the baffles are in close contact with the outer wall of the heat exchange tube.

[0019] In this technical solution, the baffle clamps the wires and prevents the return air from the indoor unit from entering the insulation box from the connection between the wires and the baffle. On the other hand, the baffle, which is close to the wall of the wire hole, prevents the return air from the indoor unit from entering the insulation box from the connection between the wire hole and the baffle. More importantly, it is close to the outer wall of the heat exchange tube, preventing the return air from the indoor unit from entering the insulation box from the connection between the heat exchange tube and the baffle. This ensures that the temperature sensor is sealed inside the insulation box and can detect the temperature of the heat exchange tube normally without interference.

[0020] Furthermore, the baffle is provided with a second slot for the wire to pass through. The second slot is semi-circular and its diameter is equal to that of the wire.

[0021] In this technical solution, this design ensures that the wires and baffles are installed close together, preventing the return air from the indoor unit from entering the insulation box from the connection between the wires and the baffles.

[0022] Furthermore, the box cover is provided with at least one pair of retaining plates, and the temperature sensing head is secured between the pair of retaining plates.

[0023] In this technical solution, a clamping plate is set to secure the temperature sensor inside the cover, facilitating the quick installation and fixation of the temperature sensor.

[0024] Beneficial effects: The technical solution of this application uses a heat insulation box to wrap the temperature sensing head of the temperature sensor and isolate it from the outside world, so as to avoid inaccurate measurement due to the return air of the indoor unit. Moreover, the heat insulation box can make the temperature sensing head and the heat exchange tube tightly and firmly in line, which is not easy to loosen. The large contact area helps to improve the measurement accuracy. Attached Figure Description

[0032] like Figure 1 As shown, this invention proposes a temperature sensing bulb installation structure, which is installed on the heat exchange tube 3 of the ventilation heat exchanger. The temperature sensing bulb installation structure includes a heat insulation box, through which the heat exchange tube 3 passes. The heat insulation box is snapped and fixed to the heat exchange tube 3. The temperature sensing head 6 of the temperature sensing bulb is located inside the heat insulation box and makes line contact with the heat exchange tube 3. When in line contact, the contact area between the temperature sensing head 6 and the heat exchange tube 3 is maximized, which helps to improve the measurement accuracy. In addition, the heat insulation box is firmly and reliably fastened to the heat exchange tube, so the temperature sensing head 6 can maintain a long-term and reliable line contact with the heat exchange tube 3, is not easy to loosen, and ensures that the detection accuracy of the temperature sensing head 6 is not affected.

[0033] The temperature sensor mounting structure on the heat exchange tube 3 in this embodiment of the invention places the temperature sensor 6 inside the heat insulation box, thus preventing it from being affected by the return air from the indoor unit and causing inaccurate measurements. Moreover, the temperature sensor 6 is parallel and in line with the heat exchange tube 3 inside the heat insulation box, resulting in a large contact area, which helps to improve measurement accuracy. In addition, the heat insulation box can be quickly snapped and fixed to the heat exchange tube 3, making installation simple and convenient.

[0034] In this embodiment, as Figure 1 As shown, the heat insulation box includes a box body 1 and a box cover 2 that are snapped together. Both the box body 1 and the box cover 2 have heat insulation properties. The heat exchange tube 3 and the temperature sensor 6 are respectively located inside the box body 1 and the box cover 2. When the box body 1 and the box cover 2 are snapped together, the heat insulation box and the heat exchange tube 3 are firmly connected and not easy to loosen or separate, ensuring that the temperature sensor 6 and the heat exchange tube 3 have a long-lasting and good contact. The connection and installation of the heat insulation box and the heat exchange tube 3 is very simple, convenient and quick. Moreover, the temperature sensor 6 is completely wrapped by the heat insulation box and isolated from the outside world, avoiding inaccurate measurement caused by the return air of the indoor unit.

[0035] Furthermore, in this embodiment, as Figure 1As shown, the box body 1 and the box cover 2 are provided with a slot 4 for accommodating the heat exchange tube 3. When the box body 1 and the box cover 2 are fastened together, the slot 4 on the box body 1 and the box cover 2 clamps the heat exchange tube 3. When the box body 1 and the box cover 2 are not fastened together, the heat exchange tube 3 can be easily inserted into the slot 4 and the temperature sensor 6 can be fixedly installed inside the box cover 2. Of course, in other embodiments, the slot 4 can also be provided only on the box body 1. With this design, the heat exchange tube 3 only passes through the box body 1. During the installation process, the heat insulation box can be installed on the heat exchange tube 3 first, and then the temperature sensor 6 can be installed, making the installation of the temperature sensor 6 more convenient.

[0036] In this embodiment, as Figure 1 As shown, the cover 2 is provided with at least one pair of retaining plates 5, and the temperature sensor 6 is clamped between the pair of retaining plates 5. The retaining plates 5 are set to clamp and fix the temperature sensor 6 in the cover 2, so as to facilitate the quick installation and fixation of the temperature sensor 6.

[0037] Correspondingly, the cover 2 is provided with a wire hole 11 for the wire 9 of the temperature sensor 6 to pass through. If the cover 2 is provided with a slot 4, the wire hole 11 is connected to the slot 4 on the cover 2. Figure 1 As shown, this design makes it easy to quickly install the temperature sensor 6. If the wire hole 11 is not connected to the slot 4, the wire 9 needs to be passed through the wire hole 11, which is more troublesome to install. If the cover 2 does not have a slot 4, the wire hole 11 is connected to the slot 4 when the box body 1 and the cover 2 are fastened together.

[0038] In this embodiment, as Figure 1 As shown, the slot 4 is semi-circular, and its diameter is equal to that of the heat exchange tube 3. Furthermore, a sealing strip 7 is provided on the wall of the slot 4. The sealing strip 7 further enhances the seal at the connection between the heat exchange tube 3 and the slot, ensuring that the return air of the indoor unit will not enter the heat insulation box and affect the measurement accuracy of the temperature sensor 6.

[0039] In this embodiment, as Figure 1As shown, a pair of baffles 8 are inserted into the wire hole 11. Each baffle 8 has a slot 12 for the wire 9 to pass through. The slot 12 is semi-circular, and its diameter is equal to the diameter of the wire 9. When the two baffles 8 clamp the wire 9, the wire 9 fits tightly against the wall of the slot 12, preventing the indoor unit's return air from entering the insulation box from the connection point between the wire 9 and the baffles 8. This ensures that the indoor unit's return air will not enter the insulation box and affect the measurement accuracy of the temperature sensor 6. In addition, the outer wall of the baffle 8 can be tightly attached to the wall of the wire hole 11 to prevent the return air from the indoor unit from entering the insulation box from the connection between the wire hole 11 and the baffle 8. Moreover, when the box body 1 and the box cover 2 are fastened together, the outer wall of the baffle 8 can also be tightly attached to the outer wall of the heat exchange tube 3, preventing the return air from the indoor unit from entering the insulation box from the connection between the heat exchange tube 3 and the baffle 8, ensuring that the temperature sensor 6 is sealed in the insulation box and can detect the temperature of the heat exchange tube 3 normally without interference.

[0040] In this embodiment, as Figure 1 As shown, one end of the box body 1 and the box cover 2 are hinged, and the other end is fastened by a snap-fit ​​10. This design makes it convenient and quick to snap the heat insulation box onto the heat exchange tube 3. Of course, in other embodiments, the box body 1 and the box cover 2 can also be set as separate parts, and the connection can be achieved by snap-fit ​​alone.

[0041] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
