Problems solved by technology
In this heat pipe, the material of the pipe body 10 is usually made of a uniform metal, such as copper. During the heat conduction process, after a certain period of time, the temperature T1 in the heat-absorbing area (that is, the end of the heat pipe that absorbs solar heat) will increase. It tends to be consistent with the temperature T2 of the heated area (close to the end of the heated body), so that there is no temperature difference between the heat-absorbing area and the heated area, which causes the gas flow inside it to slow down. As a result, the speed of heat conduction slows down and the efficiency decreases

Embodiment Construction
[0033] A preferred embodiment of the present invention is Figure 3 ~ Figure 5 As shown, the heat pipe 100 includes a long heat-absorbing shaft tube 200 and a heat conductor 300 for heat conduction. The heat-absorbing shaft tube 200 absorbs external heat (such as heat from the sun), and the heat conductor 300 conducts the absorbed heat to heated body. There is a cylindrical liquid flow space 201 in the heat-absorbing shaft tube 200 so that the liquid can freely flow and transmit heat energy. One end of the cylindrical liquid flow space 201 is sealed and the other end communicates with the inner space of the heat conductor. The heat conductor 300 is composed of a base 301, an inlay body 302 and a cap body 303, the base 301, the inlay body 302 and the cap body 303 are closely connected or integrated to form a heat conductor with an internal space 304 (see Figure 5 ), the base 301 is connected to the heat absorbing shaft cylinder 200 and the heat conductor 300, and the inner sp...

The invention relates to a heat conducting pipe which comprises a heat absorption beam barrel and a heat conducting device, wherein the heat conducting device comprises a base, a cap body and an rabbet joint body; and the rabbet and the base as well as the cap body are made of materials with different heat conductivities so as to form temperature difference in the direction of heat conduction, accelerate the conduction of heat and effectively prevent the heat from flowing backwards in the heat conducting process. The heat conducting pipe improves the heat conducting efficiency and can be widely applied to heat conducting apparatus of solar water heaters and various cooling devices.
Description
technical field [0001] The invention relates to a heat transfer device, in particular to a heat pipe for transferring heat under low pressure. Background technique [0002] Heat pipe is a device that uses the principles of capillary action and phase change to conduct heat. The heat pipe seals the working fluid in the heat pipe, and uses phase change to quickly transfer heat from high temperature to low temperature. [0003] Generally speaking, the working fluid of the heat pipe is water and alcohol. At a higher temperature, the working fluid will absorb heat from the high-temperature end, evaporate from liquid to gas, and flow through the entire heat pipe in the form of heat convection, taking heat away from the high-temperature end. When it reaches a low temperature, because the temperature at the low temperature end is low, the fluid will release heat energy at the low temperature end and condense from gas to liquid. The tube wall of the heat pipe has many small holes. T...
