Relatively speaking, the heat-conducting gel has the advantages of no stress, good plasticity, no oil separation, good storability, automatic dispensing and the like. The advantage of automatic point gluing makes the heat-conducting gel possess very high availability factor, and very convenient management.

The premise of automatic dispensing of the heat-conducting gel is to put the gel into a needle tube which can be matched with dispensing equipment, and the volumes of the needle tubes which are commonly used at present are 30cc and 300 cc. Because the heat-conducting gel has higher viscosity, a large amount of air is filled in the heat-conducting gel in the process of transferring the heat-conducting gel from the production equipment to the needle tube, and after the heat-conducting gel mixed with the air is dispensed along with the dispenser, the actual heat-conducting effect of the heat-conducting gel is greatly reduced due to the existence of the air. Most importantly, the existence of air can make the unit dispensing amount of the dispenser uncontrollable, and the dispensing efficiency is reduced.
