Problems solved by technology

However, the bottom plate of the textile heat sink adopts a fabric structure, which determines that the heat sink has characteristics different from traditional heat sinks: the flatness of the bottom surface is low; when it is wrapped on the heat source surface with different curved surfaces, the spatial arrangement of the heat dissipation units changes; Even if the bottom surface is compounded with tin to improve its flatness, the bottom plate still has a certain degree of flexibility
Therefore, the traditional fixing method cannot be used when the textile structure radiator is fixed
In addition, due to the flexible characteristics of the textile structure radiator, it breaks through the limitations o

Description

technical field [0001] The invention relates to a testing device and a testing method for the thermal resistance of a radiator of a textile structure, belonging to the technical field of textile product performance testing. Background technique [0002] At present, in the development and application of power electronic controller products, thermal resistance, as an important parameter to evaluate the heat dissipation capability of radiators, has always been the object of attention and evaluation in the industry. In order to improve the heat dissipation performance and application range of electronic components, etc., a pin-finned textile heat sink with a flexible structure (publication number: CN104400371A) has been developed. As a new type of heat sink, the thermal resistance test of the textile structure heat sink is a prerequisite for its structural design and performance optimization. [0003] At present, when performing thermal resistance testing, traditional radiator ...
