专利汇可以提供Electrokinetic heat pipe专利检索，专利查询，专利分析的服务。并且A heat pipe for transporting a large quantity of heat within a small temperature difference provided with a tube, a wick, and a fluid that can transfer heat. The tube includes an evaporator section at one end and a condenser section at the opposite end thereof. The wick is disposed uniformly against the side walls of the tube and provides a capillary action to transfer the fluid from the condenser section to the evaporator section. Heat at the evaporator section causes the fluid to evaporate, wherein the vapor is then transmitted to the condenser section where the vapor condenses, thus giving up its latent heat, and is again transmitted to the evaporator section by the wick to define a continuous flow within the heat pipe. Electrodes are disposed within the tube, one electrode being disposed adjacent to the evaporator section, and the other electrode being disposed adjacent to the condenser section. When a potential difference is applied to the electrode, an electro-osmotic flow pumping is effected within the pipe, thereby, increasing the maximum heat capability of the heat pipe or overcoming any vapor lock present in the wick. Without the applied potential difference, the heat pipe functions as either an electrokinetic power generator or as a potential generator.，下面是Electrokinetic heat pipe专利的具体信息内容。
