[background technology]:
Heat pipe is the high passive heat transfer element of a kind of heat conductivility.Heat pipe utilizes Transformation Principle and capillarity, makes the heat transference efficiency of itself exceed hundred times to thousands of times than the fine copper of same material.Heat pipe is a vacuum tube, and the hydraulic fluid that annotate the inside is the media that heat is transmitted.In the heat pipe application, the hydraulic fluid kind is a lot.The heat pipe that uses cylindrical copper pipe or steel pipe to make is the most common.Liquid sucting core structure is arranged on the heat pipe wall.The capillary force that relies on the imbibition core to produce makes condensed fluid get back to evaporation ends from condensation end.Because after inside heat pipe is evacuated, the liquid that reinjected before sealing is so the pressure of inside heat pipe is to be determined by the steam pressure after the hydraulic fluid evaporation.As long as the heat hot tube-surface, hydraulic fluid will evaporate.The temperature and pressure of evaporation ends steam all is higher than the other parts of heat pipe slightly, therefore, has produced pressure differential in the heat pipe, impels an end colder in the steam flow heat pipe.When steam on heat pipe wall condensation the time, steam is emitted the latent heat of vaporization, thereby heat is passed to condensation end.Afterwards, liquid returned evaporation ends after the liquid sucting core structure of heat pipe made condensation.As long as the thermal source heating is arranged, this process will circulate and carry out.
The imbibition core is an important component part of heat pipe body interior.The version of imbibition core will directly have influence on the performance of heat pipe and heat exchange of heat pipe.Heat pipe body of the present invention has been used imbibition core technology, adopts typical axial slot formula tube core structure.
The solar energy heating air is as a kind of emerging typical solar energy optical-thermal conversion regime, and it is gone back prematurity at present and is applied to this field generation technology.Realization of the present invention will contribute to the development of solar energy heating air electricity generation system.
[summary of the invention]:
The purpose of this invention is to provide a kind of monomer multi-channel straight rib and jacket rib compound high temperature heat pipe heater, can utilize the solar energy heating air, make the realization of solar heat air generating become possibility, this is that a kind of emerging green energy resource utilizes method.
Monomer multi-channel straight rib and jacket rib compound high temperature heat pipe heater provided by the invention is to utilize the heat of the sun with the device of air from the low-temperature heat to high temperature, is a kind of thermal power transfer product.Comprise heat pipe, the heat pipe condenser section part radially is fixed with one group of straight rib, and the straight rib number is 6 to 9.Be installed with successively and the interior jacket rib of heat pipe arranged concentric, middle jacket rib and outer jacket rib by straight rib.The two ends of interior jacket rib, middle jacket rib and outer jacket rib are fixing with drive end bearing bracket and rear end cap welding respectively, be positioned at the drive end bearing bracket outside heat collection body that fits tightly with the heat pipe evaporator section periphery is installed, be inlaid with one group of thermal-arrest ring rib that closely contacts with heat pipe evaporator section in the heat collection body, outer jacket rib and heat collection body are followed successively by heat insulation layer and shell outward, shell and heat insulation layer are provided with one group of air inlet, air inlet equidistant placement near the circumference of drive end bearing bracket.Corresponding with the air inlet position, be provided with one group of ventilating opening at middle jacket rib equally near the circumference of rear end cap and the circumference of the close drive end bearing bracket of interior jacket rib, form the ring-type air flow channel of three flow processs, air flow channel is the long-pending design of uiform section.Be provided with air outlet at the rear end cap center, air outlet is interior big outer little cone shape.The side that is positioned at housing one end in the heat pipe evaporator section outside is equipped with lens.
Advantage of the present invention and good effect:
Heat exchange of heat pipe of the present invention and other forms of heat exchanger have many advantages by comparison, but the most essential and unique have following some:
(1) good heat-transfer, monomer multi-channel straight rib and jacket rib compound high temperature heat pipe heater has good heat transfer property, at first be all to have realized ribization easily at evaporator section and condensation segment, increased the heat exchange area of cold fluid and hot fluid, reduce the thermal-convection resistance of both sides greatly, thereby strengthened whole diabatic process; Under the condition that does not change EAT, increased the mean temperature difference of cold fluid and hot fluid heat exchange in this diabatic process; Is the flow design of air in passage the annular flow of three flow processs.The reason of this three aspect can make the heat transfer property of the more other forms of heat exchanger of this heater better.
(2) heat-transfer area can freely be arranged, the heat transfer element of monomer multi-channel straight rib and jacket rib compound high temperature heat pipe heater is a heat pipe, its evaporator section, condensation segment length and ribization are than determining independently that by each sides such as given heat output, fluid temperature (F.T.), flows both sides do not involve mutually.
(3) after this heater adopts the multi-channel straight rib and jacket rib compound high temperature heat pipe technology, following characteristics are relatively arranged with other heat exchanger of equal-wattage:
1) reduces heat exchange area, dwindle heat exchanger volume.
2) the deposit allowance of the transmission heat of increase heat exchanger.
3) pressure loss of reduction fluid reduces the fluid transmission power.
By implementing the present invention, make and concentrate the heater volume of high temperature heat source heated air stream to reduce, thermal transition efficient improves, and is specially adapted to the photo-thermal conversion field of solar heat air electricity generation system.
