Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to heat conducting gel testing tool field, more specifically, relate to a single component heat conducting gel anti vertical flow testing tool. BACKGROUND
[0002] The heat dissipation process of electronic components is from the device through the interface to the heat sink, and then the heat sink dissipates heat to the environment. Because the device and the surface of the heat sink are rough and uneven on the micro level, it is difficult to form effective surface contact between the two, and air with low thermal conductivity will fill the gap between the surface of the electronic device and the heat dissipation module, ultimately resulting in unsatisfactory heat dissipation effect. In addition, with the rapid development of modern electronic technology, electronic devices have begun to develop towards high power consumption, miniaturization and integration, and their energy density has increased significantly, which has led to more and more serious heat dissipation problems, rapid increase in heat output, and possible damage to circuit board components, which not only affects the normal operation of electronic equipment, but also may cause certain safety hazards.
[0003] Currently, the main method in the industry is to fill thermal interface material between electronic devices and heat dissipation devices to improve the surface heat dissipation efficiency of electronic equipment. Compared with other thermal interface materials, heat conducting gel has the advantages of high thermal conductivity, low stress and repeatability, and is a research hotspot in the field of thermal interface materials.
[0004] Single-component gel does not need to mix other components, and can be used immediately, which is convenient to use. And it remains in a gel state during use and does not solidify, has high fluidity and thixotropy, which allows it to come into close contact with the heat dissipation surface and reduce thermal resistance. At the same time, its good thixotropy makes it easy to apply single-component heat conducting gel, which can adapt to heat dissipation surfaces of various shapes. However, because of its weak cross-linking system, it may crack after cold and hot impact or long-term thermal aging. Therefore, it is necessary to test the anti-vertical flow of single-component heat conducting gel. The existing single-component heat conducting gel anti-vertical flow testing tool is mostly complex, not convenient to disassemble and assemble, and not convenient for comparative experimental observation of different components of heat conducting gel.
