The invention discloses a method for demonstrating an influence factor of the heat-dissipating efficiency of a heat-conducting pipe heat dissipater. The method is specifically executed according to following steps of: measuring the temperature of a heat source and the temperature of environment when the heat-conducting pipe heat dissipater is not used; measuring the temperature of the heat source and the temperature of environment when the heat-conducting pipe heat dissipater is used; accurately measuring the heat-dissipating efficiency of the heat-conducting pipe heat dissipater according to a formula and clearly demonstrating the heat-dissipating mechanism of the heat-conducting pipe heat dissipater and an influence factor influencing the heat-dissipating efficiency of the heat-conducting pipe heat dissipater. Therefore, students may profoundly understand the heat-dissipating mechanism of the heat-conducting pipe and university thermotics teaching level is effectively enhanced.
Description
technical field [0001] The invention belongs to the technical field of physical measurement, and in particular relates to a method for displaying factors affecting heat dissipation efficiency of a heat conduction pipe radiator. Background technique [0002] Since the heat pipe technology was invented in 1964, it has received great attention from people, and nearly a thousand papers of this kind were published in the years before 1970. So far, heat pipe technology has been widely used in space nuclear power supply, aerospace vehicles, heat dissipation of electronic instruments, solar power generation, high-efficiency chemical reactors, etc. In recent years, high-efficiency micro-heat pipe technology, high-temperature large-scale heat pipe technology, high-efficiency heat pipe reaction equipment technology, and various high-efficiency heat pipe heat exchange technologies have all developed rapidly. However, domestic colleges and universities have not yet seen the experimental...
