Abstract
The utility model relates to a heat conduction device, particularly a thermosiphon pipe. A sealed fine and long pipe is integrally composed of a heat absorption end, a heat insulation end and a heat radiation end, and the vacuum of the sealed fine and long pipe is pumped out. The heat insulation end is positioned between the heat absorption end and the heat insulation end. Operation material is filled in the sealed fine and long pipe. The utility model is suitable for occasions with utilization of thermal diode efficiency of water heaters, etc., and is also suitable for various heat pipes.
Description
The utility model relates to a kind of heat conducting device, particularly a kind of thermal siphon.
Present siphon pipe, heat absorbing end and release end of heat are the same good elongated tubular of heat transfer coefficient, after vacuumizing, charge into operation material, closed port, because tube wall good heat-transfer, when the absorption edge temperature was lower than release end of heat or heat absorbing end temperature instability, heat was easy to pass to heat absorbing end from release end of heat, causes heat loss by tube wall, the thermal diode effect that is to say it is relatively poor, and heat transfer efficiency is corresponding not high.
The purpose of this utility model is a kind of heat transfer efficiency height of design, the siphon pipe that heat loss is very little.
The utility model is achieved in that it constitutes one by heat absorbing end, adiabatic section and release end of heat and the sealing elongated tubular that vacuumizes constitutes, and the adiabatic section is filled with operation material in the pipe between heat absorbing end and release end of heat.
Above-mentioned adiabatic section is made of the very little material of heat transfer coefficient.
The material of the utility model adiabatic section can be nonmetallic materials such as pottery, glass.
The material of the utility model adiabatic section can be the very little alloy material of heat transfer coefficient.
The utility model becomes the middle three stage structure that the adiabatic section is arranged with the siphon pipe of original one-part form, because the existence of adiabatic section, it is to be made by heat-insulating material or the very little material of heat transfer coefficient, heat loss by tube wall heat conduction just reduces greatly like this, simultaneously, when the heat absorbing end heat absorption, operation material in the pipe conducts heat rapidly in a vacuum to behind the release end of heat, when the heat absorbing end temperature is lower than release end of heat, the heat of release end of heat can not conduct to heat absorbing end because of the existence of tube wall adiabatic section yet, the thermal diode effect that is to say it is very good, has improved the thermal efficiency greatly, is a kind of enhancement mode siphon pipe.The utility model not only is applicable to thermal siphon, also is applicable to various heat pipes.Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is common siphonal organigram.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the position view that the utility model is used for solar water heater.
Among above-mentioned three figure, 1 is heat absorbing end, and 2 is operation material, and 3 is release end of heat, and 4 among Fig. 2 Fig. 3 is the adiabatic section, and 5 is the heat preservation zone of water heater among Fig. 3.Owing to having only the good material of a kind of heat conductivity, tube wall constitutes among Fig. 1, when heat absorbing end 1 temperature is high, the heat absorbing end heat absorption, operation material 2 gasifies in a vacuum rapidly and heat is conducted to release end of heat 3, the while tube wall is the conduction portion heat also, but when heat absorbing end 1 temperature is lower than release end of heat 3, also can conduct resorption hot junction 1 quickly by the tube wall heat, thermal diode effect is just very poor.And the utility model that Fig. 2 shows is because the existence of adiabatic section 4, and when heat absorbing end 1 temperature was lower than release end of heat 3, the heat of release end of heat 3 just can not passed heat absorbing end 1 back by tube wall, and thermal diode effect is just fine.Adiabatic section 4 is made of the very little material of heat transfer efficiency, can be nonmetallic materials, also can be the very little metal material of heat transfer coefficient.The adiabatic section is positioned at heat preservation zone among Fig. 3, because heat can be toward heat absorbing end 1 conduction, even heat absorbing end 1 is very low, even zubzero temperature, release end of heat 3 still can keep higher temperature the long period, solar water heater also can well be played a role in the winter of cold, adopt the thermal efficiency of water heater of the present utility model to improve more than 20%.The utility model is when being used as the thermal siphon of solar water heater, and the adiabatic section preferably is arranged at the edge of water heater heat preservation zone.
The utility model goes for heat pipe, and heat pipe is that above-mentioned siphon pipe inwall is provided with the net formation, adopts the utility model, and the thermal efficiency of heat pipe is improved equally.
