Description

Technical Field

[0001] This utility model relates to the field of air conditioning temperature acquisition technology, specifically an air conditioning temperature acquisition device. Background Technology

[0002] The normal operation of a bus air conditioning system requires the collection of numerous temperature parameters. The air conditioning control system uses these collected temperature parameters to calculate and determine the operation of refrigeration components such as the air conditioning compressor, fan, electronic expansion valve, and four-way valve, according to the corresponding operating logic.

[0003] Current methods for collecting temperature data from bus air conditioning systems involve fixing temperature sensors to the corresponding locations on the air conditioning system's pipes using metal cable ties or thermally conductive adhesive. This installation process is cumbersome and not very secure. Furthermore, because the contact area between the temperature sensor and the air conditioning pipes is very small and the thermal conductivity is low, this directly leads to delays and inaccuracies in the collected temperature parameters. Over time, oxide films or even corrosion can form at the contact points between the temperature sensor and the air conditioning pipes, severely affecting the collected temperature parameters and ultimately impacting the accurate operation of the air conditioning system.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0020] Please see Figure 1-5 In this embodiment of the present invention, an air conditioner temperature acquisition device includes a metal tube 1, a spring plate 2, and a temperature sensor 3. The metal tube 1 is made of copper and is welded to the pipeline of the air conditioner core 4. A spring plate 2, made of stainless steel, is installed inside the metal tube 1. The temperature sensor 3 is installed on the metal tube 1 at the location of the spring plate 2. The diameter of the metal tube 1 is 8mm, the length of the metal tube 1 is 30mm, and the thickness of the metal tube 1 is 0.5mm. The diameter of the temperature sensor 3 is 5mm, and the length of the temperature sensor 3 is 25mm. Because the copper tube is welded to the air conditioning system piping that needs temperature data acquisition, it has a large contact area, rapid and accurate heat conduction, and the contact surface will not loosen, oxidize, or rust. In addition, the temperature sensor is tightened and fixed inside the copper tube by a stainless steel spring sheet, making the installation firm, simple, and quick, eliminating the tedious installation process and improving the efficiency of workers. Compared with manual binding, it avoids the hidden dangers of loose binding and difficulty in controlling binding force caused by human factors. Similarly, the stainless steel spring sheet increases the heat-receiving contact area of ​​the temperature sensor, making heat conduction faster and more accurate, and making later maintenance and replacement more convenient.

[0021] The spring sheet 2 includes a first bending portion 21, a horizontal portion 22, a second bending portion 23, and a folded portion 24. The first bending portion 21 is provided at one end of the horizontal portion 22, and the second bending portion 23 is provided at the other end of the horizontal portion 22 in the opposite bending direction to the first bending portion 21. The folded portion 24 is provided at the end of the second bending portion 23 away from the horizontal portion 22. The first bending portion 21 is perpendicular to the horizontal portion 22, and the second bending portion 23 is inclined relative to the horizontal portion 22.

[0022] The working principle of this utility model is as follows: A section of copper tube with a diameter of ∅8×30×0.5T mm is brazed onto the air conditioning system pipeline where temperature needs to be collected. A stainless steel spring is then installed inside the copper tube, and finally, a ∅5×25 temperature sensor is inserted into the copper tube. Because the copper tube is brazed onto the air conditioning system pipeline where temperature needs to be collected, the contact area is large, heat conduction is fast and accurate, and the contact surface will not loosen, oxidize, or rust. In addition, the temperature sensor is tightened and fixed inside the copper tube by the stainless steel spring, making the installation firm, simple, and quick, eliminating the tedious installation process and improving the work efficiency of workers. Compared with the manual binding process, it avoids the hidden dangers of loose binding and difficulty in controlling binding force caused by human factors. Similarly, the stainless steel spring increases the heat-receiving contact area of ​​the temperature sensor, making heat conduction faster and more accurate, and making subsequent maintenance and replacement more convenient.
