The overall coefficient K of heat transfer is an important parameter in the design of heat insulation cabinet. The cabinet performance of heat insulation can be tested rapidly and exactly by developing testing equipment which can detect k-value quickly and automatically. The paper emphatically explains the design scheme, testing principle and application example of a quick testing equipment for k-value. Testing results prove that the testing equipment can work steadily and accurately, and have a good application effect.
