Tool and method for testing heat transfer performance of vapor chamber

The invention discloses a vapor chamber heat transfer performance test tool and method, and the test tool comprises a test clamp, an upper cold plate, a lower cold plate, a fan assembly, a heating resistor, a first thermocouple and a second thermocouple, and the test clamp comprises a first clamp part and a second clamp part. A to-be-tested temperature-uniforming plate is fixed between the first clamp part and the second clamp part, the upper cold plate and the lower cold plate are fixedly arranged at the tops and the bottoms of the first clamp part and the second clamp part respectively, the fan assembly is fixedly arranged on the upper cold plate, and the heating resistor is installed in the center of the to-be-tested temperature-uniforming plate. The first thermocouple is fixed in the center of the heating resistor, and the second thermocouple is fixed in the middle of the rib of the test fixture. By designing the device for testing the structure and function integrated temperature-uniforming plate suitabl
