Description

Technical Field

[0001] This utility model belongs to the field of temperature control box testing technology, and in particular relates to a temperature control box tester. Background Technology

[0002] Aircraft engines and other critical components generate significant heat during normal operation. Lubricating oil, as a crucial lubricant and coolant, needs to maintain its temperature within a specific range to ensure safe flight. This relies on the precise operation of the temperature control box. The WKH-27B temperature control box works by using an oil temperature sensor to monitor real-time oil temperature changes. The sensor transmits the collected temperature signal to the control box, which amplifies and processes it before outputting a corresponding control signal. This signal controls a reversible electric mechanism to adjust the opening of the oil cooler's damper, stabilizing the oil temperature within the specified range. When the temperature control box malfunctions, it requires repair using a temperature control box testing device.

[0003] Existing temperature control box testing equipment has several significant shortcomings. The equipment is typically bulky, making it inconvenient to carry and move between different locations, which greatly hinders maintenance and testing work. Current equipment cannot quickly test and troubleshoot aircraft lubricating oil temperature control boxes in emergency situations. With the continuous development of the aviation industry, the requirements for aircraft operation and maintenance efficiency are increasing, and traditional large, inconvenient testing equipment is no longer sufficient to meet the demands of rapid response and flexible operation in modern aircraft maintenance. Summary of the Invention

[0039] See appendix Figures 1 to 5 This paper presents an illustrative embodiment of the temperature control box tester proposed in this utility model. The temperature control box tester consists of a box body 1, a test interface 3, a potentiometer, a control circuit board, a touch screen display 5, a printer 6, a power supply, and a power switch 7.

[0040] The enclosure 1 can be made of aluminum frame. Aluminum has a relatively low density and sufficient strength. The aluminum frame structure of enclosure 1 is lightweight and has good load-bearing capacity. The dimensions of enclosure 1 are 320mm×220mm×180mm. The upper side of enclosure 1 is also symmetrically equipped with handles 13, which meets the requirements of small size and portability, and can quickly and flexibly complete the relocation and maintenance work.

[0041] The side surface of the chamber 1 is provided with multiple vent holes 11. During the operation of the temperature control box tester, the various components inside the chamber will generate heat. The vent holes 11 allow the heat to be dissipated through natural convection, preventing the temperature inside the chamber from overheating and improving the reliability and service life of the temperature control box tester.

[0042] The surface of the enclosure 1 is equipped with a control panel 2, which integrates multiple control functions of the temperature control box tester onto a single interface. Operators can achieve unified control of the temperature control box tester simply by operating the control panel 2, improving testing efficiency and saving time and effort. Specifically, the test interface 3, touch display screen 5, power switch 7, and potentiometer knob 4 (including the potentiometer) are all located on the control panel 2.

[0043] Test interface 3 connects to the temperature control box via a test cable. Since the temperature control box controls the operation of the damper's electric mechanism, a problem with the damper's electric mechanism may indicate a fault in the temperature control box. Therefore, it is necessary to test the damper's electric mechanism to determine if the problem lies with the temperature control box. In this embodiment, the test cable is a one-to-three converter cable provided according to usage requirements. The one-to-three converter cable connects to both the temperature control box and the lubricating oil radiator damper's electric mechanism. Connecting the damper's electric mechanism to the circuit allows for testing.

[0044] A potentiometer is located inside housing 1 and is used to connect to and test the temperature control box. Specifically, the continuously adjustable potentiometer replaces the temperature sensor and connects to the temperature control box to test the heating and cooling resistance values ​​of the temperature control box in automatic mode. The potentiometer includes a potentiometer knob 4, which is located on control panel 2. The operator manually rotates the potentiometer knob 4 to change the resistance value. The adjustment method of rotating the knob is very intuitive, and the operator can accurately adjust the resistance value according to the testing requirements.

[0045] The control circuit board is located inside housing 1. It is connected to a potentiometer to acquire detection data and output the results. Specifically, the control circuit board can calculate the adjustment point and the non-sensitive zone based on the heating and cooling resistance values ​​of the temperature control box measured by the potentiometer.

[0046] The touch display screen 5 is embedded in the control panel 2, ensuring a secure and stable installation. This embedded design provides physical protection for the touch display screen 5, preventing damage from accidental impacts or scratches. The touch display screen 5 connects to the control circuit board and is used to acquire and display detection results, presenting them intuitively. In this embodiment, the touch display screen 5 is an industrial touch display screen. Industrial touch display screens are more durable, effectively dustproof and waterproof, and can withstand accidental impacts and vibrations during operation. They can also operate stably over a wider temperature range.

[0047] The internal storage capacity of the temperature control box tester is limited. To expand the storage capacity, in this embodiment, a USB port 12 is provided on the rear side of the housing 1. The USB port 12 is used to connect an external USB storage device. Connecting an external USB storage device can effectively back up the test data, preventing data loss in the event of a malfunction of the temperature control box tester and ensuring data security.

[0048] Printer 6 is located inside housing 1 and is connected to touchscreen display 5 to obtain and print test results. In this embodiment, printer 6 includes a paper tray and a printer cover. The paper tray is located inside housing 1 and is used to hold printing paper. The printer cover is located on the rear side of housing 1 and has a paper outlet. When the printing paper runs out, it needs to be replaced with new paper. To facilitate the replacement, the printer cover is equipped with an arc-shaped lever. Pulling the arc-shaped lever outwards opens the printer cover and allows printing paper to be placed into the paper tray.

[0049] The power supply is connected to the potentiometer, control circuit board, touch screen 5, and printer 6 to provide operating power. The power switch 7 is located on the control panel 2 and is connected to the power supply to control the power on and off of the temperature control box tester.

[0050] To ensure the temperature control box tester can operate normally under different power supply environments, in this embodiment, the power supply has a DC 27V interface 8 and an AC 220V interface 9. The DC 27V interface 8 is located on the control panel 2, and the AC 220V interface 9 is located on the rear side of the enclosure 1. In locations with AC power supply, such as most indoor environments, the AC 220V interface 9 can be used for power supply, taking advantage of the convenience of the AC power grid. In some special situations, only DC power supply is available. In this case, the DC 27V interface 8 will function to ensure that the temperature control box tester is not unusable due to power incompatibility.

[0051] Since the DC 27V interface 8 is located on the control panel 2, on the upper surface of the housing 1, dust can easily enter when not in use. If dust enters the interface, it may cause poor contact, increase resistance at the interface, or even lead to electrical faults such as short circuits. To avoid this, in this embodiment, the temperature control box tester also includes a dust cover 81, which is located at the DC 27V interface 8. The dust cover 81 effectively prevents dust from entering the interface, ensuring the stable electrical performance of the DC 27V interface 8.

[0052] The power switch 7 is a rotary switch that can rotate around its central axis. When the power switch 7 is in the middle position, it is in the off state. Rotating the power switch 7 in the first direction connects to the DC power supply mode, and rotating the power switch 7 in the second direction connects to the AC power supply mode. Using a rotary switch to control the power supply on / off or power supply mode switching is convenient, and the position of the rotary switch can intuitively reflect the current power status.

[0053] The temperature control box tester can automatically detect whether the temperature control box is functioning properly. To handle automatic detection failures or malfunctions, manual detection should also be included. In this embodiment, the temperature control box tester also includes a resistance box interface 10, which is located on the control panel 2 and is used to connect an external resistance box. Specifically, in automatic mode, using the potentiometer located inside the box 1, rotating the potentiometer knob 4 will cause the control circuit board to automatically record the resistance when the oil radiator damper electric mechanism moves, and calculate the adjustment point and non-sensitive area after automatically recording the upper and lower points. In manual mode, an external resistance box is connected through the resistance box interface 10, and data is manually input into the temperature control box tester for saving via the touch screen display 5.

[0054] The temperature control box tester has open-loop and closed-loop functions, indicating whether a physical damper motor mechanism is connected. When no physical damper motor mechanism is connected, it can be adjusted to open-loop mode, and the temperature control box can be tested separately using a potentiometer or an external resistance box. When a physical damper motor mechanism is connected, it can be connected to the temperature control box tester to complete the physical testing.

[0055] In the above illustrative embodiment, all components of the temperature control box tester are integrated into the box, which is small in size and portable, making it easy to use in different locations and enabling quick and flexible maintenance of the temperature control box.

[0056] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0057] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
