The bushing-type heat tube comprises an outer tube and a heat exchanging tube, wherein the heat exchanging tube is arranged inside the outer tube, the upper end and the lower end of the heat exchanging tube respectively stretch out from the upper end and the lower end of the outer tube, vacuum is formed between the outer tube and the heat exchanging tube after being sealed by an upper cover and a lower cover, and working substances are filled between the upper cover and the lower cover. The lower end of the heat exchanging tube is a cold water inlet, and the upper end of the heat exchanging tube is a hot water outlet. When the bushing-type heat tube disclosed by the utility model works normally, the temperature and flowrate of the cold water flowing inside the inner tube can be adjusted according to the temperature and the flowrate of the hot air blowing outside the outer tube, so ultra-high heat efficiency can be obtained. A plurality of heat tubes can be connected in parallel to use in the engineering.
Description
Technical field
The utility model relates to a kind of bushing type heat pipe, belongs to the heat power engineering field.
Background technology
Heat pipe is a kind of novel heat transfer element with high heat conductivility, and it transmits heat by the evaporation of liquid in the Totally enclosed vacuum pipe with condensing.Inside heat pipe is pumped into negative pressure state, charges into suitable liquid (being working medium), and this boiling point of liquid is low, easily volatilization.Heat pipe one end is evaporator section (abbreviation hot junction), an other end is condensation segment (an abbreviation cold junction), when heat pipe evaporator section is heated, liquid in the capillary evaporates rapidly, steam flows to an other end under small pressure differential, and discharges heat, and regelation becomes liquid, liquid flows back to evaporator section again, and so circulation is more than.Mix heat abstractor at condensation end when using usually, derive heat.Therefore, research uses the heat pipe of directly deriving heat to be of practical significance.
Summary of the invention
The purpose of this utility model is to propose a kind of bushing type heat pipe, changes the structure of existing heat pipe, to improve the thermal efficiency of heat pipe.
The bushing type heat pipe that the utility model proposes, comprise outer tube and heat exchanger tube, heat exchanger tube places outer tube, and stretch out from the top and bottom of outer tube respectively the top and bottom of heat exchanger tube, form vacuum by loam cake and lower cover sealing back between outer tube and the heat exchanger tube, charge into working medium between loam cake and the lower cover; The lower end of heat exchanger tube is a cold water inlet, and the upper end of heat exchanger tube is a hot water outlet.
The bushing type heat pipe that the utility model proposes, when operate as normal, the temperature and the flow of the hot gas of blowing over outward according to outer tube, the cold water temperature and the flow that flow in the pipe in regulating can obtain the high thermal efficiency.Can be on the engineering with the use in parallel of many heat pipes.

Among Fig. 1, the 1st, cold water inlet, the 2nd, lower cover, the 3rd, outer tube, the 4th, loam cake, the 5th, hot water outlet, the 6th, heat exchanger tube, the 7th, liquid refrigerant.
The specific embodiment
The bushing type heat pipe that the utility model proposes, its structure comprise outer tube 3 and heat exchanger tube 6 as shown in Figure 1, and heat exchanger tube 6 places outer tube 3, and stretch out from the top and bottom of outer tube 3 respectively the top and bottom of heat exchanger tube 6.Form vacuum by loam cake 4 and lower cover 2 sealing backs between outer tube 3 and the heat exchanger tube 6, charge into liquid refrigerant 7 between loam cake and the lower cover.The lower end of heat exchanger tube 6 is a cold water inlet 1, and the upper end of heat exchanger tube is a hot water outlet 5.
The bushing type heat pipe that the utility model proposes, interior pipe and outer tube be by up and down ring-like lid sealing, between liquid refrigerant is housed, by on the blast pipe that covers the gas between outer tube 3 and the heat exchanger tube 6 discharged form vacuum.During normal operating conditions, high-temperature gas is vertically blown over outer tube, and heat is exceedingly fast and is transferred to interior pipe, and heated water is by cold water inlet 1 input of heat exchanger tube 6 lower ends, from the hot water outlet 5 upper ends output of heat exchanger tube upper end.The bushing type heat pipe can many in parallel uses.The vapour of the liquid refrigerant 7 of inside heat pipe, liquid phase become conducts heat, and thermal resistance is very little, compares with metals such as silver, copper, aluminium, and the heat pipe of Unit Weight can transmit the heat of several magnitude more.Very high heat conductivility is arranged.The steam of heat pipe inner chamber is in saturation state, the pressure of saturated vapor is decided by saturation temperature, and it is very little that saturated vapor flows to the pressure drop that condensation segment produces from evaporator section, according to the equation in the thermodynamics as can be known, temperature drop is also very little, thereby heat pipe has good isothermal.Heat pipe can independently change the heating surface (area) (HS of evaporator section or cooling section, promptly with less heating surface (area) (HS input heat, and with bigger film-cooled heat quantity of heat given up, the heat transfer area input heat that perhaps heat pipe can be bigger, and with less film-cooled heat quantity of heat given up, so promptly can change heat flow density, solve the insoluble heat transfer difficult problem of some additive methods.
The bushing type heat pipe manufacture process that the utility model proposes is: diameter is that outer tube 3 and the diameter of L is D2 length greater than the heat exchanger tube 6 of L by lower cover 2 and loam cake 4 welding for D1 length, loam cake 4 is provided with a blast pipe, earlier between outer tube 3 and heat exchanger tube 6, pour into an amount of liquid refrigerant less than the pipeline of blast pipe internal diameter by blast pipe with external diameter, bleed with heating integral heat pipe or vavuum pump, gas is discharged from blast pipe, after the exhaust blast pipe is shut, between outer tube 3 and heat exchanger tube 6, formed vacuum.Hot gas is blown over from outer tube 3 outsides during use, and heated water enters from water inlet 1, and the heat exchanger tube 6 of flowing through flows out continuous operation from hot water outlet 5.
A kind of bushing type heat pipe that the utility model proposes, operation principle is: make full use of evaporation heat transfer, make that outer tube and heat exchanger tube two ends temperature difference are very big, heat is conducted fast.Inside heat pipe is pumped into negative pressure state, charges into suitable liquid (being working medium), and this boiling point of liquid is low, easily volatilization.The outer tube of heat pipe is an evaporator section, heat exchanger tube is a condensation segment, when heat pipe evaporator section is heated, liquid in pipe working medium is evaporated rapidly, and steam flows to an other end under small pressure differential, and discharges heat, regelation becomes liquid, liquid flows back to the bottom, space between outer tube and the heat exchanger tube again, and so circulation is more than, and heat is reached in the water of heat exchanger tube by the heat pipe outer tube.This circulation is carried out fast, and heat can be come by conduction continuously.
