Technical Field

[0001] The utility model relates to a temperature rise testing device, belonging to the technical field of temperature rise testing. Background Art

[0002] There are two general types of traditional temperature rise tests: leaded thermocouple testing and thermal imaging testing, which involves partially or completely removing the product casing. The traditional thermocouple test is wired, requiring complex procedures for attaching test wires and limiting the test range. Traditional handheld thermal imaging testing devices can only test the device under test after it is opened, making it impossible to accurately measure the temperature rise of the device after it is actually sealed. The measurement results can only be used as a reference.

[0003] Existing technologies face a series of problems when conducting temperature rise tests, such as the complexity of test preparation, the limitation of test scope and insufficient simulation of equipment working conditions. These problems lead to low test efficiency and inaccurate test results. Utility Model Content

[0009] A circuit board, on one side of which the temperature detection sensor unit, the signal processing unit, and the power supply unit are arranged in sequence from left to right;

[0010] A self-adhesive insulating tape layer is provided on the other side of the circuit board and is used to adhere the device to any adhesive position inside the product to be tested.

[0011] Furthermore, the temperature detection sensor unit adopts an infrared sensor array, and the infrared sensor array is used to receive infrared rays emitted by internal components of the product to be tested and convert them into electrical signals.

[0012] Furthermore, the signal processing unit converts the electrical signal from the infrared sensor array into a high-speed serial signal.

[0013] Furthermore, the power supply unit includes a wired power supply and a wired cascade interface. The power supply unit is connected to an external power source in a wired manner and realizes the cascade of multiple device circuits, and finally outputs to an external temperature display unit.

[0014] Furthermore, the power supply unit also includes a battery, and the battery is used to power the temperature measuring device and the wireless conversion module in the wireless mode.

[0015] Furthermore, the wireless conversion module is a wireless receiving module that converts the high-speed serial signal of the signal processing unit into a wireless signal and finally outputs it to the external temperature display unit.

[0016] Furthermore, the self-adhesive insulating tape layer is made of a heat-resistant and insulating material, specifically one of silicone rubber, chlororubber, and polytetrafluoroethylene.

[0017] Furthermore, the self-adhesive insulating tape layer allows the temperature rise test device to be installed at different locations of the product, including the inner wall of the device's housing, near a circuit board, or adjacent areas of a heat-generating component, to achieve wide-range temperature detection.

[0018] The beneficial effects of the utility model are:

[0019] When using a temperature rise testing device, the inspector first sticks the device around the object to be tested, and then starts the device, so that the infrared sensor array inside the temperature detection sensor unit can convert the infrared rays emitted by the internal components of the object to be tested into corresponding electrical signals. The received electrical signals are processed by the signal processing unit and converted into serial high-speed signals. Finally, the temperature information inside the product to be tested is displayed on the external temperature display unit through wired transmission or wireless transmission. In the wired transmission mode, the detection devices share signal lines in a cascade manner to achieve signal integration and transmission of multiple device units; in the wireless transmission mode, a wireless signal conversion module with a battery is used to power the temperature measuring device and the wireless conversion module, and the detection information is received through a wireless receiving module added to the external temperature display unit.
