A kind of heat pipe being used on aluminium alloy melting furnace
Technical field
The utility model relates to aluminum alloy processing technology field, relates to specifically a kind of heat pipe being used on aluminium alloy melting furnace.
Background technology
Hot pipe technique is a kind of heat transfer element with high thermal conductivity growing up nearly decades, and heat pipe is applied to space industry the earliest, and even to this day, the equal gentle temperature control application extension from Aero-Space is to the other field application of industrial technology.Along with hot pipe technique uses in industrial circle in decades maturation and the reduction of cost, the utilization making it on kiln becomes possibility.Traditional heat pipe exchanger, the problem such as common to exist heat exchange efficiency not high, manufactures relative complex, and later stage heat exhaustion phenomenon is serious, has therefore restricted the further raising of heat exchange efficiency.
Summary of the invention
The utility model is low in order to solve conventional heat pipe heat exchanger effectiveness, and baroque defect provides a kind of heat pipe that can circulating transfer heat.
The purpose of this utility model is achieved through the following technical solutions: a kind of heat pipe being used on aluminium alloy melting furnace, comprise shell, return duct, vapor chamber, liquid-sucking core, insulating segment, evaporator section, condensation segment, wherein heat pipe can be divided into three phases vertically, it is evaporator section, insulating segment and condensation segment, form a high vacuum closed system, part before insulating segment is evaporator section, part is afterwards condensation segment, insulating segment is that evaporator section and condensation segment are separated, simultaneously for working medium provides passage and make intraductal working medium not carry out heat transmission with the external world, shell seals, return duct is between vapor chamber and shell, in vapor chamber, be provided with liquid-sucking core, on liquid-sucking core, soak completely can transferring heat working medium.
The beneficial effects of the utility model are: the structure manufacture of heat pipe is simpler, and cost is relative also lower, and heat constantly reaches condensation segment from evaporator section, form the heat transmission system of a circulation, have improved the efficiency of exchange heat.

The specific embodiment
Below in conjunction with embodiment, the utility model is described further.
The technical solution of the utility model is: a kind of heat pipe being used on aluminium alloy melting furnace, comprise shell 1, return duct 2, vapor chamber 3, liquid-sucking core 4, insulating segment 5, evaporator section 6, condensation segment 7, wherein heat pipe can be divided into three phases vertically, it is evaporator section 6, insulating segment 5 and condensation segment 7, form a high vacuum closed system, part before insulating segment 5 is evaporator section 6, part is afterwards condensation segment 7, insulating segment 5 is that evaporator section 6 and condensation segment 7 are separated, simultaneously for working medium provides passage and make intraductal working medium not carry out heat transmission with the external world, shell 1 seals, return duct 2 is between vapor chamber 3 and shell 1, in vapor chamber 3, be provided with liquid-sucking core 4, on liquid-sucking core 4, soak completely can transferring heat working medium.
During work, the heat of external heat source, shell 1 by evaporator section 6 rises the temperature of liquid working substance with the heat conduction of soaking the liquid-sucking core 4 of full working medium, fluid temperature rises, and at liquid surface evaporation, the vapour pressure until reach capacity, now heat is passed to steam in the mode of latent heat, the full vapour pressure of closing of evaporator section 6 is along with fluid temperature rises and raises, under the effect of pressure reduction, steam flows to all lower condensation segments 7 of pressure and temperature by steam cavity 3, and condensation on the gas-liquid interface of condensation segment 7, emits latent heat.Liberated heat by being full of the heat conduction of liquid-sucking core 4 and the shell 1 of working medium, is passed to the outer low-temperature receiver of heat pipe from gas-liquid interface, and the liquid of condensation is back to evaporator section 6 by return duct 2, completes a circulation.And so forth, constantly heat is reached to condensation segment 7 from evaporator section 6, adiabatic section 5, except providing passage for working medium, also plays a part evaporator section 6 and condensation segment 7 to separate, and makes intraductal working medium not carry out heat transmission with the external world.
