Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat sinks, and particularly relates to a heat sink thermal efficiency full-detection test system. BACKGROUND

[0002] A heat sink is a passive or active thermal management device based on the principle of heat conduction. It is a physical structure made of high thermal conductivity materials such as metals. It transfers the redundant heat generated by heat sources in electronic devices, mechanical systems or heating systems to air or liquid cooling media through optimized design of finned surfaces with high surface area, and ultimately realizes the key heat exchange component of temperature control target. Its efficiency depends on the synergistic effect of three elements: material thermal conductivity, contact thermal resistance and convective heat transfer efficiency.

[0003] After the production of the heat sink is completed, it needs to be detected to ensure that its performance, safety and reliability meet the expected requirements; for example, detection can prevent overheating of equipment from causing fire or electric shock hazards by verifying that the heat source temperature is within a safe threshold; or testing the efficiency of the heat sink, such as heat dissipation and heat transfer coefficient, to ensure that heat can be effectively transferred.

[0004] Therefore, the Chinese patent document with publication number CN215492485U discloses an automobile heat sink product detection table, which includes a fixing module, the fixing module includes a detection table, a first clamping piece and a second clamping piece, a containing groove is arranged on the detection table, the first clamping piece and the second clamping piece are symmetrically arranged in the containing groove and have the same structure; and a detection module, the detection module includes a heat dissipation piece, a timing piece and a heating sheet, the heat dissipation piece and the heating sheet are arranged in the containing groove, the timing piece is arranged on the detection table, the timing piece is connected with the heating sheet, and the heating sheet is connected with the heat dissipation piece; the technical scheme disclosed by the patent document can detect how long the heat dissipation effect of the heat sink can be maintained under high temperature for a long time, so as to obtain a complete efficiency detection of the heat sink, and the heat sink will not have functional deviation when in use.

[0005] However, the disclosed automobile radiator product detection station still has the technical problem of being unable to detect the thermal efficiency of the radiator. Specifically, when detecting the thermal efficiency of the radiator, a standardized detection platform needs to be built based on the principles of thermodynamics and fluid mechanics, so that the core performance parameters of the radiator, including the heat dissipation, heat transfer coefficient, thermal resistance, and environmental adaptability, can be quantitatively evaluated through the integrated temperature control module, flow monitoring unit, and data acquisition system. The thermal efficiency test system can use a combination of steady-state and transient test methods to simulate the thermal load changes under actual working conditions, and record the heat medium flow, inlet and outlet temperature difference, and surface temperature distribution in real time using high-precision sensors, ultimately generating a full-dimensional detection report covering thermal performance, structural reliability, and energy efficiency ratio, providing data support for radiator design optimization and quality certification. Therefore, there is an urgent need for a high-efficiency detection system that can detect the thermal efficiency of the radiator. SUMMARY

Actual measurement: the error of the 5th iteration scheme is <2%. In addition, the present application also has a resource-saving design, with 10-second pre-test consuming only 0.8% of the energy of formal test, while the traditional scheme requires 30 minutes of preheating. The present application also has a fault fuse protection mechanism, such as real-time monitoring of dT / dt over-limit value, such as >10℃ / s, immediately terminating the test and alarming. As can be seen, the aforementioned process compresses the test scheme development time from the traditional manual estimation of 2 hours to 90 seconds through the closed loop of "parameter input → simulation rehearsal → data-driven decision → dynamic calibration", and the scheme failure probability is reduced to below 1%.

[0039] The AI-driven test process can automatically optimize formal test parameters such as step power value and sampling frequency through pre-test closed-loop iteration, and can reduce invalid test time by 40%. At the same time, the defect diagnosis performance can be enhanced, such as using multi-modal fusion analysis to synchronously process surface temperature field of infrared thermal imaging, ultrasonic flowmeter based on internal flow resistance, and abnormal sound detection data of microphone array, and through graph neural network, composite defects such as micro-channel blockage, positioning accuracy ±0.5mm, virtual welding of welding, recognition rate 99.2%, and material fatigue crack with minimum detection size of 50um can be located.
